The Lathe & Its Uses Or, Instruction in the Art of Turning Wood and Metal. Including a Description of the Most Modern Appliances for the Ornamentation of Plane and Curved Surfaces. With an Appendix, in Which is Described an Entirely Novel Form of Lathe for Eccentric and Rose Engine Turning; a Lathe and Planing Machine Combined; and Other Valuable Matter Relating to the Art.

Among the various uses to which a lathe may be put, wheel-cutting is one of the most important, so many pieces of mechanism requiring cogged wheels of various pitches and forms...

There are also many cheaper firms than those alluded to, where the work is rather of rough-and-ready style; all depends on what _class_ of work the would-be purchaser proposes t...

The following is a very excellent self-centering chuck now coming into extensive use. It has been noticed in more than one periodical. The description annexed is extracted from...

A modification of the latter, communicated to the _English Mechanic_, is shown in Fig. 16A. Its construction and mode of application is sufficiently evident without a detailed d...

The remarks of the above eminent mechanic upon this subject, as also those of Professor Willis and Mr. Babbage have been embodied in a very excellent paper by Dodsworth Haydon,...

The first requisite for fitting up a lathe for screw-cutting and plain turning is the fitting a guide-screw, and adding a saddle to the slide-rest. But it must be observed that...

Principle may be looked upon as the essence of practice, and in connection with this particular subject, the reduction of practice to principle is of comparatively modern growth...

The faults in the above simple machine are many. In the first place no provision is here made for the advance of the tool towards the work. In the second place the requisite fir...

The instrument just described is evidently unsuited for the drills and bead tools which present a concave edge like 246 A, B, C, enlarged sketches of tools copied from Holtzapff...

Thus tools may be broadly divided into two classes--viz., single-edged and double-edged--remembering always that this distinction refers to the manner in which they should act,...

Most of the steel cutters may be made by the amateur, the metal being turned to the required shape and the teeth cut by small files or punches while the material is in a soft st...

The way of using the spherical rest is thus described by Mr. Hoblyn:--"When altogether, and the point of tool adjusted by means of a square exactly over centre of pivot, it is e...

Fig. 130 is another form of boring tool for large and heavy work. A boss, A, is fixed to the cutter bar, having a series of dovetailed grooves, or slots, on its surface, in whic...

"I think the plan to be described will produce to a certainty any required number of screws and turns to the inch. The screws are entirely cut with a common comb tool, but start...

The slide rest used by the watch case turners is almost identical in form with one figured and described by Bergeron. It is necessary that the tool holder should have a circular...

There seems no reason why the same result should not be arrived at by communicating a movement to the rest supporting the cutting tool in the following manner:--Let A, A, be lat...

Although the title of this work is sufficient to declare its contents, a few prefatory remarks may not be superfluous as to its design and the manner in which that design has be...

We must now return from this digression to speak of other applications of the slide rest. It is evident that when connection is made between the overhead and a pulley on the scr...

Fig. 299 is a section of the chuck which carries the rosette, the latter being shown in position. A, is the body of the chuck; B, the inside screw to fit the mandrel. On the out...

We will now return from this explanatory digression to the work in hand. Having cut down the flange for the cover to nearly the required size, proceed to hollow out the box. Wor...

The next class of spirals is that in which no central core exists, but the coils stand separate and distinct, two or more rising from the same base. The coils are sometimes flat...

The proper chuck for this work is the capped ball chuck already described, by loosening the cap of which any one of the six openings may be brought under the action of the tool,...

It has been already stated that for the production of spiral work revolving cutters are preferable to fixed ones, unless, indeed, it is required to finish up a perfectly round t...

The outside must be turned in a similar manner, and a hole drilled to receive a pointed bar or wrench, for the purpose of unscrewing it when screwed up tightly. To turn up a fac...

These two castings, 401 and 402, are bolted together with two bolts and nuts through the holes 5 and 6, as shown in Fig. 400. Fig. 403, is a back view of the additions, showing...

The following remarks on the work of this cutter frame on flat surfaces only, will be useful to the reader in designing and working out the various combinations of circles, inte...

The Machines usually on hand consist of large and small Boring and Drilling Machines; Universal Shaping, Planing, Slotting, Bolt-screwing, Single and Double ended Punching and S...
