Part 13

FOLDING AND EXTENSION TABLE.--C. Mayer, Sullivan, Ill.--This invention relates to improvements in tables, and consists in arranging the side rails of the top of the frame, which are enlarged at the center and hinged to the posts for folding against the cross rails, when the top, which is detachably connected, is removed, for economy of space and convenience, in packing for transportation or storage; also in arranging the legs for folding up against the under edge of the cross rails; also in an improved arrangement of the side rails for extension.

MANUFACTURE OF SCOOPS.--S. Geo. Knapp, Woodhaven, N.Y.--This invention relates to an improved mode of manufacturing sheet-metal flour, grain, and other scoops, and consists in forming the bowls in one piece of metal, without seams or joints, by stamping up sheets of metal into the form of a trough, with a flange around the top, and cutting the same transversely in the center, with blanks for the bowls of two scoops, to be finished by trimming or shaping the cut ends, turning down the flange at the top, for stiffening either over wire or not and attaching the handle; the object being to produce scoops with bowls formed in one piece, and shaped at the base or in the part where the handles are connected, and to smoothly effect an economy of labor by stamping two blanks at one blow of the drop press, and also to control the metal under the action of the drop better in shaping the deep curved part of the base so as to upset and stiffen the blanks thereat.

BORING MACHINE.--E.C. Barton, Bloomsburg, Pa.--This invention relates to improvements in wood-boring machines, whereby it is designed to provide a simple and efficient arrangement of frame operating devices and feeding table for boring light articles to be presented to the machine by hand.

HASP LOCK.--E.R. Culver, New London, Conn.--This invention relates to improvements in that class of locks where the locking devices are incased within a hasp, and a hook is used in connection with the hasp for locking, or independently for fastening the door without locking.

WATER WHEELS.--W.J. Thompson, Springfield, Mo.--This invention relates to improvements in that class of horizontally running wheels, which receive the water from above or below on curved buckets taking the water at one side and discharging it at the other, and it consists of an improved arrangement of vertically oscillating gates, which, when open, form chutes for the water; it also consists of an improved means for working the gates.

PIPE COUPLING.--J.D. Ware, Savannah, Ga.--This invention relates to improvements in pipe couplings, and consists in forming a dovetailed groove across the end of one part, with an annular recess in the bottom around the bore for a packing ring, and fitting on the other part a dovetailed projection for engaging in the groove, and in arranging on one of the parts an eccentric ring to work against the head of the projection and force it tightly into the groove.

FIRE GRATES.--G.W. Everhart, Louisville, Ky.--This invention relates to improvements in that class of fire grates used for heating rooms, and consists in so arranging them as to provide a clear air space between the basket and the walls of the fire-place, both at the back and ends, for the admission of air more directly at these parts, for the better combustion of the coal and the gases arising therefrom; it also consists in providing a recess in the hearth or bottom of the fire-place under the grate, for the reception of ash pans of greater capacity than can be contained on the top of the hearth, whereby a much larger quantity of cinders and ashes may be received and retained, so that less frequent removals of the same will be required.

APPARATUS FOR SEWING SADDLERY AND OTHER LEATHER, OR STRONG MATERIALS.--Auguste Jacques Hurtu and Victor Joseph Hautin, Paris France.--This invention relates to apparatus more especially applicable for sewing leather, saddlery, harness, and other similar work with waxed thread, and consists first, in the improved apparatus of this invention, two needles are employed, the one sewing as an awl, and the other carrying the thread; the two needles have at the same time a vertical movement and also an adjustable horizontal movement. The needles are operated alternately, so that the needle may pass the thread through the hole made just previously by the awl, before the leather has been moved forward. By this means the sewing may be carried on with great regularity, and the material be turned in any direction in order to execute small designs. Secondly, the invention relates to improvements in the arrangement of the shuttle, whereby it is caused to pass through the loops formed by the waxed thread without touching it.

PACKING AND ATOMIZING CAN.--F.L. Palmer, Sr., New York city.--This invention relates to improvements in cans for packing insect powder and other like finely powdered substances which, in use, require to be delivered in atomic jets for penetrating crevices where insects secrete themselves, and it consists in providing such cans with stoppers having nozzles, through which stoppers or nozzles the passages are temporarily closed in a way to be readily opened for use; also, in providing the cans with nozzles at or near the bottom temporarily plugged in which tubes may be connected so that the powder may, when required for use, be readily blown out in atomic jets, whereby the said cans are made to subserve the uses of packing cans and discharging atomizing cans, with but trifling additional expense, whereas, at the present time, users of such powders are compelled to buy expensive atomizing cans, to which the powder must be transferred from the packing cans, before it can be properly used, or in the absence of such cans the powder is scattered in an ineffectual and wasteful way in or about the resorts of the insects.

REMEDY TOR RHEUMATISM.--H.H. Munroe, Louisville, Ky.--This invention relates to a new and useful improvement in a remedy for rheumatism.

NEW BOOKS AND PUBLICATIONS.

ELOCUTION AND ORATORY. Giving a Thorough Treatise on the Art of Speaking and Reading. With numerous Selections of Didactic, Humorous, and Dramatic Styles.

The author of this valuable treatise is Prof. Charles A. Wiley, of Fort Plain, N.Y. The instructions are valuable and the selections admirable; and we can very cordially recommend it to all who would improve either in speaking or reading. Such a book is worthy a place in every family.

SPECIMENS OF FANCY TURNING EXECUTED ON THE HAND OR FOOT LATHE. With Geometric, Oval, and Eccentric Chucks, and Elliptical Cutting Frame. By an Amateur. Illustrated by Thirty exquisite Photographs. Philadelphia: Henry Carey Baird, Industrial Publisher, 406 Walnut Street.

The beauty of these photographs is indescribable; they must be seen to be appreciated. The designs from which they were taken were executed by a gentleman well known to us, and who is undoubtedly one of the most expert turners on this continent. The price of the work by mail, free of postage, is $3.00.

THE NATIONAL WAGES TABLES, Showing at a glance the Amount of Wages, from Half an Hour to Sixty Hours at $1 to $37 per Week, also from One Quarter of a Day to Four Weeks, at $1 to $37 per Week. By Nelson Row, Publisher, No 149 Fulton street, New York.

This little work, which our readers will find advertised in another column, must prove an almost indispensable help in the counting rooms of establishments employing large numbers of workmen at varying rates of wages. It is one of the best things of the kind we have ever seen, and we give it earnest commendation.

DIRECTIONS FOR COOKING. By Miss Leslie. Price, by mail, $1.50.

Henry Carey Baird, of Philadelphia, has just published a new edition of Miss Leslie's "Old Standard and Renowned Cookery," being the sixtieth edition of a book which has stood the test of time and practice, and is a valuable aid in every household.

BENNY.

S.R. Wells, of this city, has published in pretty form "Benny," a Christmas ballad, by Annie Chambers Ketchum, a poem which has already appeared in the _Phrenological Journal_.

The prospectus of EVERY SATURDAY, for 1870, by Fields, Osgood & Co. of Boston, promises to give us that excellent journal in a new and enlarged form, with the additional attraction of illustrations, engraved from designs by leading European artists. This publication will therefore hereafter present weekly, not only the cream of European literature, but the cream of European art. The high character of the publishers of this journal is an ample guarantee that this promise will be fulfilled in the most satisfactory manner.

LIPPINCOTT'S MAGAZINE, for January, also presents a varied and select bill of fare, containing among other things, Part XIII. of Robert Dale Owen's novel "Beyond the Breakers," "The Fairy and the Ghost," a Christmas tale, with six amusing illustrations; a curious and interesting article on "Literary Lunatics," by Wirt Sikes, "Our Capital," by William R. Hooper, and very much more excellent matter in the way of stories poems, and essays.

The "Mobile Weekly Register," the oldest Democratic paper in the South, is said to have reached a larger circulation than was ever attained by any journal South of Mason and Dixon's line. It is full of interesting varied matter, having an able agricultural department, presided over by the veteran editor and successful agriculturist, Hon. C.C. Langdon. Its general literature, poetry, stories, etc., make it highly acceptable to the ladies. The year will open with a new continued story, of deep interest, by one of the most distinguished writers of the day. The price was recently reduced to $3.00 per year, which, for so large a paper (12 pages), is extremely cheap.

We have received the January number of "Demorest's Mirror of Fashions," a work that interests the ladies. Also "Demorest's Young America," a fine magazine for boys and girls. Both these serials are well published by Mr. and Madame Demorest of this city.

U.S. Patent Office

How to Obtain Letters Patent for New Inventions.

Information about Caveats, Extensions, Interferences Designs, Trade Marks; also, Foreign Patents.

For a period of nearly twenty-five years, MUNN & CO. have occupied the position of leading Solicitors of American and European Patents, and during this extended experience of nearly a quarter of a century, they have examined not less than fifty thousand alleged new inventions, and have prosecuted upward of thirty thousand applications for patents, and, in addition to this, they have made, at the Patent Office, over twenty thousand preliminary examinations into the novelty of inventions, with a careful report on the same.

The important advantages of MUNN & CO.'S Agency are, that their practice has been ten-fold greater than that of any other Agency in existence, with the additional advantage of having the assistance of the best professional skill in every department, and a Branch Office at Washington, which watches and supervises, when necessary, cases as they pass through official examination.

CONSULTATIONS AND OPINIONS FREE.

Those who have made inventions and desire a consultation are cordially invited to advise with MUNN & CO. who will be happy to see them in person at the office, or to advise them by letter. In all cases, they may expect an HONEST OPINION. For such consultations, opinion, and advice, NO CHARGE is made. A pen-and-ink sketch and a description of the invention should be sent.

TO APPLY FOR A PATENT,

a model must be furnished, not over a foot in any dimension. Send model to MUNN & CO., 37 Park Row, New York, by express, charges paid, also, a description of the improvement, and remit $16 to cover first Government fee, and revenue and postage stamps.

The model should be neatly made, of any suitable materials, strongly fastened, without glue, and neatly painted. The name of the inventor should be engraved or painted upon it. When the invention consists of an improvement upon some other machine, a full working model of the whole machine will not be necessary. But the model must be sufficiently perfect to show with clearness the nature and operation of the improvement.

PRELIMINARY EXAMINATION

is made into the patentability of an invention by personal search at the Patent Office, among the models of the patents pertaining to the class to which the improvement relates. For this special search, and a report in writing, a fee of $5 is charged. This search is made by a corps of examiner of long experience.

Inventors who employ us are not required to incur the cost of a preliminary examination. But it is advised in doubtful cases.

COST OF APPLICATIONS.

When the model is received, and first Government fee paid, the drawings and specification are carefully prepared and forwarded to the applicant for his signature and oath, at which time the agency fee is called for. This fee is generally not over $25. The cases are exceptionally complex if a higher fee than $25 is called for, and, upon the return of the papers, they are filed at the Patent Office to await Official examination. If the case should be rejected for any cause, or objections made to a claim, the reasons are inquired into and communicated to the applicant, with sketches and explanations of the references; and should it appear that the reasons given are insufficient, the claims are prosecuted immediately, and the rejection set aside, and usually WITHOUT EXTRA CHARGE TO THE APPLICANT.

MUNN & CO. are determined to place within the reach of those who confide to them their business, the best facilities and the highest professional skill and experience.

The only cases of this character, in which MUNN & CO. expect an extra fee, are those wherein appeals are taken from the decision of the Examiner after a second rejection; and MUNN & CO. wish to state very distinctly, that they have but few cases which can not be settled without the necessity of an appeal; and before an appeal is taken, in any case, the applicant is fully advised of all facts and charges, and no proceedings are had without his sanction; so that all inventors who employ MUNN & CO. know in advance what their applications and patents are to cost.

MUNN & CO. make no charge for prosecuting the rejected claims of their own clients before the Examiners and when their patents are granted, the invention is noticed editorially in the SCIENTIFIC AMERICAN.

REJECTED CASES.

MUNN & CO. give very special attention to the examination and prosecution of rejected cases filed by inventors and other attorneys. In such cases a fee of $5 is required for special examination and report, and in case of probable success by further prosecution, and the papers are found tolerably well prepared, MUNN & Co. will take up the case and endeavor to get it through for a reasonable fee, to be agreed upon in advance of prosecution.

CAVEATS

Are desirable if an inventor is not fully prepared to apply for a Patent. A Caveat affords protection, for one year, against the issue of a patent to another for the same invention. Caveat papers should be carefully prepared. The Government fee on filing a Caveat is $10, and MUNN & Co.'s charges for preparing the necessary papers are usually from $10 to $12.

REISSUES.

A patent when discovered to be defective, may be reissued by the surrender of the original patent, and the filing of amended papers. This proceeding should be taken with great care.

DESIGNS, TRADE MARKS, AND COMPOSITIONS

can be patented for a term of years, also, new medicines or medical compounds, and useful mixtures of all kinds. When the invention consists of a medicine or compound, or a new article of manufacture, or a new composition, samples of the article must be furnished, neatly put up. Also, send a full statement of the ingredients, proportions, mode of preparation, uses, and merits.

PATENTS CAN BE EXTENDED.

All patents issued prior to 1861, and now in force, may be extended for a period of seven years upon the presentation of proper testimony. The extended term of a patent is frequently of much greater value than the first term; but an application for an extension, to be successful, must be carefully prepared. MUNN & Co. have had a large experience in obtaining extensions, and are prepared to give reliable advice.

INTERFERENCES

Between pending applications before the Commissioners are managed and testimony taken; also, Assignments, Agreements, and Licenses prepared. In fact, there is no branch of the Patent Business which MUNN & Co. are not fully prepared to undertake and manage with fidelity and dispatch.

FOREIGN PATENTS.

American inventors should bear in mind that five Patents--American, English, French, Belgian, and Prussian--will secure an inventor exclusive monopoly to his discovery among ONE HUNDRED AND THIRTY MILLIONS of the most intelligent people in the world. The facilities of business and steam communication are such, that patents can be obtained abroad by our citizens almost as easily as at home. MUNN & Co. have prepared and taken a larger number of European Patents than any other American Agency. They have Agents of great experience in London, Paris, Berlin, and other Capitals.

A Pamphlet, containing a synopsis of the Foreign Patent Laws, sent free. Address

MUNN & CO., 37 Park Row, New York.
