Chapter 8

The batten _B_ is in two pieces. The top piece serves as a brace for the spring (Fig. _G_, 209) and the bottom piece as a support for the bolt (Fig. _H_, 209 and 212). The battens may be made of a piece of board. The bolt (Fig. _H_, 212) works free upon a nail in the left-hand end and rests in the catch (Fig. _K_, 215) on the door-jamb.

The guard (Fig. _J_, 216) fits over the bolt and keeps it in place. The notch in the guard must be long enough to give the bolt free play up and down.

The spring (Fig. _G_, 209) is fastened with a nail to the door in such a manner that its thin end rests upon the top of the bolt with sufficient force to bend the spring and hold the bolt down in the catch (Fig. _K_, 215).

The thumb-latch (Fig. _L_, 213) is whittled out in the form shown, and fastened in a slot cut in the door by a nail driven through the edge of the door (Fig. _M_, 213) and through a hole in the thumb-latch (Fig. _L_, 213). On this nail the latch works up and down.

Fig. 217 shows the outside of the door and you can see that by pressing down the thumb-latch on the outside it will lift it up on the inside, and with it the bolt lifts up the free end of the latch and thus unfastens the door.

The handle (Figs. 217 and 214 _N_) is used in place of a door-knob. It is made of yellow birch bent in hot water.

The Deming Twin Lock

E. W. Deming, the painter of Indian pictures, the mighty hunter, and fellow member of the Camp-Fire Club of America, is a great woodsman. Not only is he a great woodsman but he is the father of _twins_, and so we have thought that he possesses all the characteristics necessary to entitle him to a place in this book, and after him and his twins we have named the twin bolts shown by Fig. 208.

The lower or Hall bolt is shot into a hole in the door-sill, and the upper or Billy bolt is shot into a hole in the door-jamb above the door. The holes should be protected upon the surface of the wood by pieces of tin or sheet iron with holes cut in them to admit the bolt. The tins may be tacked over the bolt-hole in the sill for the Hall bolt and on the bolt-hole overhead for the Billy bolt, and it will prevent the splitting away of the wood around the holes.

Guards

Two guards, _A_ and _B_ (Fig. 208), made as in Fig. 216, protect the bolts and act as guides to keep them from swinging out of position; two springs _C_ and _D_ (Fig. 208), made of well-seasoned hickory and attached to the battens on the door by nails or screws, force the bolts down and up into the bolt-holes (Fig. 208). To release the bolts, the spring must be drawn back as shown by the dotted lines in Fig. 208. This may be done by means of a string or picture wire, which is fastened in the ends of the bolts and runs through a hole in the ends of the spring and is attached to the lever _E_ (Fig. 208). When the end of this lever is pushed down into the position shown by the dotted line and arrow-point, it lifts up the Hall bolt at the bottom of the door and pulls down the Billy bolt overhead, thus unfastening the door.

Fig. 208. Fig. 209. Fig. 210. Fig. 211. Fig. 212. Fig. 213.

Fig. 214. Fig. 215. Fig. 216. Fig. 217.

But, of course, if one is outside the door one cannot reach the lever _E_; so, to overcome this difficulty, a hole is bored through the central batten of the door and the latch-string is tied to the top end of the lever and the other end is run through the hole bored in the door (Fig. 208).

The end outside of the door is then tied to a nail; by pulling the nail you pull down the lever _E_, which undoes the bolts and opens the door.

When it is desired to leave the door locked, after it is closed, push the nail into the latch-string hole so that only the head will be visible from the outside. When the nail and string are arranged in this manner, a stranger will see no means of opening the door, and, as there are many nail-heads in all rough doors, the one to which the latch-string is attached will not attract the attention of any one who is unacquainted with the Deming twin bolt.

THE AURES LOCK LATCH

THE Aures lock differs from the preceding ones in the use of metal springs, but wooden ones may be substituted; for instance, a wooden spring like the one in Fig. 209 may be put under the bolt or latch shown in Fig. 219, which is practically the same latch; that is, if you turn the latch in Fig. 209 upside down it will make the latch shown in Fig. 219; also, if you take the bolt or lock _B_ in Fig. 219 and make it of one piece of wood with a spring to it, like the one shown in Fig. 208 or Fig. 209, or make it exactly like the one shown in Fig. 201, the Aures lock can be made altogether of wood. But with this lock, as described below, metal springs were used (Figs. 219, 220, and 221).

The Door

The door shows the two strings _H_ and _K_ coming through gimlet holes near the top. Fig. 218 represents the outside of the door. The strings may be concealed by covering their ends with a board as shown in this diagram, but even if they are not concealed, one unacquainted with the lock will not know how to work them in order to open the door.

_A_ in Figs. 219, 220, and 221 is the latch which is made of a piece of wood about eight or nine inches long by about one and one half inches wide by an inch or three quarters of an inch thick. A hole is drilled near the centre of the latch and a screw placed through which is screwed into the door so that the latch will extend about two or three inches beyond the end of the door.

_D_ (Figs. 219, 220, and 221) is a catch or stop which is fastened to the door-jamb and keeps the end of the latch from flying too far up to lock the door.

_B_ (Fig. 219) is the key which is made of the same sort of wood as the latch; a hole is drilled in this also but it is here placed about one inch from the top. A screw is run through this, as in the hole in the latch, and screwed into the door (Fig. 219).

Fig. _C_, 219 is a small block of wood on which a steel-band spring has been screwed to keep the key in its proper place. The block is screwed to the door a short distance above the top of the key.

Fig. _J_, 219 is a nail or peg placed in the door close beside the key when the key is vertical; this is intended to prevent the key from being shoved over too far by the force of the band spring _F_.

Fig. 219 _L_ is a steel wire spring (a window-shade spring will answer the purpose), fastened to the door at one end and to the latch at the other end, and serves to keep the latch down and in place when locked.

Fig. 219 _K_ is the latch-string, one end of which is fastened to one end of the latch and the other end run through a hole near the top of the door and extending outside the same as the latch-string (Fig. 218).

Fig. 219 shows the positions of the latch and key when the latch is locked; to open the lock from the outside it is necessary to pull the key string first (_H_, Fig. 220), which releases the key; then pull the latch-string, thus lifting the latch while still holding the key string. The key string is now let go; the spring forcing the key into the position shown in Fig. 221 will keep the door unlocked.

When leaving the room, all that is necessary is to pull the key string which lifts the key, then let go the latch-string, and the latch will spring back to its locked position and the key will also fly back into its position as in Fig. 219. Any one not knowing the combination will be unable to open the door.

The Compass Lock

This lock is made on the same principle as the combination safe lock, but it is a lock any bright boy can make for himself. In the first place, instead of numbers, use compass divisions; that is, use a disk with the points of the compass scratched on it and an ordinary door-knob with an index mark filed on its base, as shown by Fig. 224 where the finger is pointing.

Hunt up three old door-knobs like those shown in Figs. 222, 224, and 225. When you take one of the door-knobs off one end of the shaft you will find several small screw holes in the steel shaft (Fig. 222). Over this end you set a block of hardwood which you fashion out of a square block (Fig. 223) by first cutting off the corners as shown by the dotted lines, then whittling the angles off until it becomes rounded like a compass face; after which saw off an arc, that is, part of a circle, as shown in Figs. 224, 226, and 227. Next make a square hole through the centre of the circle to fit the square end of the steel shaft of the door-knob. The square hole is not the centre of the block as it is now cut, but it is the centre of the block as it was when it was round; that is, the centre of the circle. Insert the square end of the steel shaft into the square hole in the block, and, through a hole carefully drilled for the purpose, put a screw down through the hole in the end of the steel shaft (Fig. 224); this will firmly fix the block on the end of the knob. Of course, the knob must be inserted through the door before the block is permanently fastened upon the end of the shaft. Fig. 225 shows the edge of the door with the three knobs in place. If these knobs are so turned (Fig. 226) that their flat edges are parallel with the crack of the door, there is nothing to prevent you from opening the door; but if the knobs are so turned (Fig. 227) that the blocks overlap the crack of the door, the door cannot be opened without breaking the lock.

It is evident that we must have some sort of a mark to tell us how to make the proper combination so that the door may be opened. To do this, take the metal washer of the door-knob (the upper figure in Fig. 228) or a circular piece or disk of tin and divide it up like a compass (Fig. 228). Fasten these disks securely on to the door with nails or screws; place all of the disks with the north point pointing to the top of the door and in line with each other. File in the circular base of each door-knob (Fig. 224) a little notch at the black mark where the finger is pointing, then put the door-knobs in place and fasten them there (Fig. 225) by screwing the block on their ends (Fig. 224) and securing the screws in the blocks by running them through the shaft. Carefully turn the knobs so that the block on the inside fits like those shown in Fig. 226. Jot down in your notebook the position of the index on each knob (finger point, 224); one may read northeast, another may read southwest, and another may read south. When one wants to open the door one must turn the knobs so that they will read according to the notes and the door may be opened; but unless the indexes read as noted some of them will be turned as in Fig. 227, locking the door, and it may not be opened.

When the door is closed, twist the knobs around and it will lock them so that no one else can open the door unless they know the combination. The fact that there _is_ a combination will not be suggested to a stranger by the compasses, although it might be suggested if there were figures in place of compass points. But even supposing they did suspect a combination it would take a long time for them to work it out, and no one would do it but a thief. A burglar, however, would not take the time; he would pry open the door with his "jimmy" and, as I have said before, these locks are for the purpose of keeping out tramps, vagrants, and inquisitive boys.

We have no locks yet invented which will keep out a real, professional burglar if he has reason to suppose there are valuables inside.

The safety of your log cabin depends principally upon the fact that valuables are not kept in such shacks, and real burglars know it.

THE AMERICAN LOG CABIN

NOW that we know how to make doors and door-latches, locks, bolts, and bars, we may busy ourselves with building an American log cabin. It is all well enough to build our shacks and shanties and camps of logs with the bark on them, but, when one wishes to build a log cabin, one wants a house that will last. Abraham Lincoln's log cabin is still in existence, but it was built of logs with no bark on them. There is a two-story log house still standing in Dayton, O.; it is said to have been built before the town was there; but there is no bark on the logs. Bark holds moisture and moisture creates decay by inviting fibrous and threadlike cousins of the toadstool to grow on the damp wood and work their way into its substance. The bark also shelters all sorts of boring insects and the boring insects make holes through the logs which admit the rain and in the end cause decay, so that the first thing to remember is to peel the logs of which you propose to build the cabin. There is now, or was lately, a log cabin on Hempstead Plains, L. I., near the road leading from Mineola to Manhassett; it is supposed to have been built when the first white settlers began to arrive on Long Island, but this was what was known as a "blockhouse," a small fort. In 1906 Mr. I. P. Sapington said: "I think that I am the only man now living who helped build General Grant's log cabin." Grant's house was what is popularly known in the South as a "saddle-bag" log house, or, as the old Southwestern settlers called it, a "two-pen," the pens being two enclosures with a wide passageway or gallery between them, one roof extending over both pens and the gallery.

General Grant was not afraid of work, and, like a good scout, was always willing to help a neighbor. He had a team of big horses, a gray and a bay, and the loads of cord-wood he hauled to St. Louis were so big that they are still talked of by the old settlers. In the summer of 1854 Grant started his log cabin, and all his neighbors turned in to help him build his house.

American Log House

The American log house differs from the Canadian log house principally in the shape of the roof. Our old settlers made steep gambrel roofs to shed the rain.

"Gambrel! Gambrel? Let me beg You'll look at a horse's hinder leg; First great angle above the hoof, That's the gambrel, hence the gambrel roof."

The Canadians put very flat roofs on their log cabins, usually composed of logs laid over the rafters, making them strong enough to support the heavy weight of snow. The American log cabins, as a rule, are built in a milder climate, and the flat sod roof is peculiar to our Northern boundary and the hot, arid parts of our country. We build the chimneys outside of our log cabins because, as the old settlers would say, "thar's more room out thar" (see Figs. 271, 273).

One-Pen Cabin

Fig. 229 is a one-pen cabin. To build it we first snake our logs to a skid near the site of our proposed cabin (Fig. 167), from which we can roll our logs to our house as we need them. Lay out the corners and square them (Fig. 180); notch the logs with a rounded or U-shaped notch (Fig. 165). Remember that all the logs should be two or three feet longer than the walls of the proposed building, but the notches must be the same distance apart in order to make even walls. The protruding ends of the logs may be allowed to stick out as they happen to come, no matter how irregular they may be, until the cabin is erected; then with a two-handed saw and a boy at each end they can be trimmed off evenly, thus giving a neat finish to the house.

Fig. 229. Fig. 230. Fig. 231. Fig. 232. Fig. 233. Fig. 234.

Sills

The largest, straightest, and best logs should be saved for sills or foundations. If you are building a "mudsill," that is, a building upon the ground itself, the sill logs will be subject to dampness which will cause them to rot unless they are protected by some wood preservative.

Wood Preservative

If the logs are painted with two or three coats of creosote before they are laid upon the ground, it will protect them for an indefinite time and prevent decay. Hugh P. Baker, dean of the New York State College of Forestry, writes me that--

two or three applications of warm oil with a brush will be very helpful and will probably be all that the ordinary man can do. Creosote is the best preservative because of its penetrating power and the way it acts upon the fibres of wood, and in the end is cheaper than a good many other things which have been used to preserve timber. In fact, various forms of creosote are best-known preservers of organic matter. There is no advantage in using charcoal at all and I presume suggestions have been made for using it because we know that charred wood is more durable. Linseed-oil is good; ordinary white-lead paint will be better, but neither of them is as effective as creosote, and both are more expensive. You will find that carbolineum and other patent preparations are recommended very highly; they are good but expensive and the difference in price between these patent preparations and ordinary creosote is much larger than is justified by their increased value. Creosote can be procured in large or small quantities from a number of concerns. I think we have been getting it for about ten dollars per barrel of fifty or fifty-three gallons.

Creosote

may be purchased in large or small quantities from various manufacturing companies, such as the Barret Manufacturing Company, 17 Battery Place, New York City, and the Chattfield Manufacturing Company, Carthage, O., handle it in large quantities.

Openings

Build the pen as if it were to have no openings, either doors, windows, or fireplaces. When you reach the point where the top of the door, window, or fireplace is to be (Fig. 229) saw out a section of the log to mark the place and admit a saw when it is desired to finish the opening as shown in the diagram and continue building until you have enough logs in place to tack on cleats like those shown in Figs. 229, 230, and 231, after which the openings may be sawed out. The cleats will hold the ends of the logs in place until the boards _U_ (Fig. 232) for the door-jambs, window-frames, or the framework over the fireplace can be nailed to the ends of the logs and thus hold them permanently in place. If your house is a "mudsill," wet the floor until it becomes spongy, then with the butt end of a log ram the dirt down hard until you have an even, hard floor--such a floor as some of the greatest men of this nation first crept over when they were babies. But if you want a board floor, you must necessarily have floor-joists; these are easily made of milled lumber or you may use the rustic material of which your house is built and select some straight logs for your joists. Of course, these joists must have an even top surface, which may be made by flattening the logs by scoring and hewing them as illustrated by Figs. 123, 124, and 125 and previously described. It will then be necessary to cut the ends of the joist square and smaller than the rest of the log (Fig. _A_, 229); the square ends must be made to fit easily into the notches made in the sill logs (_B_, Fig. 229) so that they will all be even and ready for the flooring (_C_, Fig. 229). For a house ten feet wide the joists should be half a foot in diameter, that is, half a foot through from one side to the other; for larger spans use larger logs for the joists.

Foundation

If your house is not a "mudsill" you may rest your sill logs upon posts or stone piles; in either case, in the Northern States, they should extend three feet below the ground, so as to be below frost-line and prevent the upheaval of the spring thaw from throwing your house "out of plumb."

Roofing

All the old-time log cabins were roofed with shakes, splits, clapboards, or hand-rived shingles as already described and illustrated by Figs. 126, 128, 129, and 130; but to-day they are usually shingled with the machine-sawed shingle of commerce. You may, however, cover the roof with planks as shown by Fig. 233 or with bark weighted down with poles as shown by Fig. 234. In covering it with board or plank nail the latter on as you would on a floor, then lay another course of boards over the cracks which show between the boards on the first course.

Gables

The gable ends of the cabin should be built up of logs with the rafters of the roof running between the logs as they are in Figs. 229 and 233, but the roof may be built, as it frequently is nowadays, of mill lumber, in which case it may be framed as shown by Figs. 49, 51, and the gable end above the logs filled in with upright poles as shown in Figs. 173 and 247, or planked up as shown in the Southern saddle-bag (Fig. 241), or the ends may be boarded up and covered with tar paper as shown in Fig. 248, or the gable end may be shingled with ordinary shingles (Fig. 79).

Steep Roof

Remember that the steeper the roof is the longer the shingles will last, because the water will run off readily and quickly on a steep surface and the shingles have an opportunity to dry quickly; besides which the snow slides off a steep roof and the driving rains do not beat under the shingles. If you are using milled lumber for the roof, erect the rafters at the gable end first, with the ridge board as shown in Fig. 263 and in greater detail in Fig. 49. Put the other rafters two or three feet apart.

Let your roof overhang the walls by at least seven or eight inches so as to keep the drip from the rain free of the wall. It is much easier for the architect to draw a log house than it is for a builder to erect one, for the simple reason that the draughtsman can make his logs as straight as he chooses, also that he can put the uneven places where they fit best; but except in well-forested countries the tree trunks do not grow as straight as the logs in my pictures and you must pick out the logs which will fit together. Run them alternately butt and head; that is, if you put the thick end of the log at the right-hand end of your house, with the small end at the left, put the next log with the small end at the right and thick end at the left; otherwise, if all the thick ends are put at one side and the small ends at the other, your house will be taller at one end than at the other as is the case with some of our previous shacks and camps (Figs. 190, 191, and 192) which are purposely built that way.

If it is planned to have glass window lights, make your window openings of the proper size to fit the window-frames which come with the sashes from the factory. In any case, if the cabin is to be left unoccupied you should have heavy shutters to fit in the window opening so as to keep out trespassers.

Chinking

If your logs are uneven and leave large spaces between them, they may be chinked up by filling the spaces with mud plaster or cement, and then forcing in quartered pieces of small logs and nailing them or spiking them in position. If your logs are straight spruce logs and fit snugly, the cracks may be calked up with swamp moss (Sphagnum), or like a boat, with oakum, or the larger spaces may be filled with flat stones and covered with mud. This mud will last from one to seven or eight years; I have some on my own log cabin that has been there even a longer time.
