The cross-head G, reciprocated by the shaft D, is provided with antifriction rollers e e, adapted to guides ƒ ƒ, secured to the under side of the table A, so that the reciprocation of this cross-head may be accompanied with as little friction as possible.

To the under side of a wooden chopping-block Jis secured an annular rib h, adapted to and bearing in an annular groove i in the table A. (See Figs. 1 and 2.) This annular groove or channel is not of the same depth throughout, but communicates at one or more points (two in the present instance) with pockets or receptacles j j deeper than the groove and containing supplies of oil, in contact with which the rib h rotates, so that the continuous lubrication of the groove and rib is assured. The rod H passes through and is guided by a central stand K, secured to the table A, and projecting through a central opening in the choppingblock without being in contact therewith, the upper portion of the said stand being contained within a cover k, which is secured to the block, and which prevents particles of meat from escaping through the central opening of the same.

The cross-head I, previously referred to, and shown in perspective in Fig. 4, is vertically adjustable on the rod H, and can be retained after adjustment by a set-screw x, the upper end of the rod being threaded for the reception of nuts, which resist the shocks imparted to the crosshead when the knives are brought into violent contact with the meat on the chopping-block.

The knives d d are adjustable independently of each other and of the said cross-head, so that the coincidence of the cutting-edge of each knife with the face of the chopping-block may always be assured.

I prefer to carry out this feature of my invention in the manner shown in Fig. 4, where it will be seen that two screw-rods m m rise vertically from the back of each knife and pass through lugs n n on the crosshead, each rod being furnished with two nuts, one above and the other below the lug through which it passes. The most accurate adjustment of the knives can be effected by the manipulation of these nuts.

A circular casing p is secured to the chopping-block, so as to form on the same a trough P for keeping the meat within proper bounds; and on the edge of the annular rib h, secured to the bottom of the block, are teeth for receiving those of a pinion q, which may be driven by the shaft D through the medium of any suitable system of gearing, that shown in the drawing forming no part of my present invention.

This shaft D may be driven by a belt passing round the pulleys 8, or it may be driven by hand from a shaft W, furnished at one end with a handle t, and at the other with a cog-wheel R, gearing into a pinion on the said shaft D.

A platform T may be hinged, as at w, to one edge of the table A, to support a vessel in which the chopped meat can be deposited. The means by which it may be supported, and the most convenient method of disposing of it when not in use, are shown in Fig. 1.

I am aware that prior to my invention meat-chopping machines have been made with vertically-reciprocating knives operating in conjunction with rotating chopping-blocks. I therefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by letters patis

ent,

1. The combination, in a meat-chopping machine, of a rotary choppingblock having an annular rib h, with a table having an annular recess i and a pocket j communicating with the said recess, all substantially as set forth.

2. In a meat-chopping machine, the combination of a rotary choppingblock with a reciprocating cross-head carrying knives d d, each of which is vertically adjustable on the said cross-head independently of the other, substantially as described.

3. The knife d, having two screw-rods, m m, attached to its back, substantially as shown, for the purpose specified.

4. The combination, in a meat-chopping machine, of the reciprocating rod H, carrying the knives d d, the cross-head C secured to the said rod, and having anti-friction rollers e e, with guides ff, adapted to the said rollers, all substantially as set forth.

14. FOR A COMPOSITION OF MATTER.

To all whom it may concern :

A. B.

Be it known that I, A. B., a citizen of the United States, residing at L., in the county of M., and State of N. [or subject, etc.], have invented a new and useful composition of matter to be used for the removal of hair and grease from hides preparatory to tanning (for which I have obtained a patent in Great Britain, No., dated February 25, 18-), of which the following is a specification.

My composition consists of the following ingredients, combined in the proportions stated, viz:

These ingredients are to be thoroughly mingled by agitation. In using the above-named composition the hides should first be freed from all salt and impurities, by soaking green hides one day and dry hides eight days, and then placing the hides so cleaned in the said solution, and allowing them to remain in it forty-eight hours. The hides are then to be removed from the solution and unhaired in the usual way.

By the use of the above composition the hair is speedily and thoroughly loosened, and the hides, while retaining all of that portion of the substance which can be converted into leather, are at the same time entirely cleaned from grease and other substances which would prevent them from being tanned quickly.

I am aware that a composition consisting of soda-ash, water, lime, and sulphur has been used for the same purpose, and that a patent therefor was granted to C. D., July 10, 18—, No.- I am also aware that saltpeter has been used in depilatory processes; but I am not aware that all of the ingredients of my composition, in the proportions stated, have been used together.

What I claim, and desire to secure by letters patent of the United States, is

The herein-described composition of matter to be used for depilating hides and preparing them for being tanned, consisting of water, unslaked lime, soda-ash, saltpeter, and flowers of sulphur in the proportions specified.

15. FOR A DESIGN.

To all whom it may concern :

Be it known that I, A. B., a citizen of the United States, residing at L., in the county of M., and State of N. [or subject, etc.], have invented and produced a new and original design for watch-cases or lockets, of which the following is a specification, reference being had to the accompanying drawings, showing a part thereof.

Figure 1 is a sectional view of a watch-case showing ny design; Fig. 2, a side elevation of same, and Fig. 3 an edge view, these three views being deemed necessary to fully illustrate my design.

The leading feature of my design consists in a raised scalloped surface, the outlines of which, when viewed in elevation, as in Fig. 2, will fall entirely within the circular outline or circumference in the center.

A is the center of the case, which is circular in its general contour, and B B are the lids. These are also circular in their outer contour where they meet the center, but have scallops C C C on them substantially as represented in the several figures. The irregular outline of the scalloped surface falls within the outer contour line of the case, thus presenting to the eye the combined effect of a smooth circular outline and a scalloped outline within it.

Within the smooth open field of each of the lids, centrally set thereupon, is the shield-shaped figure D, having upon its outer periphery also a scalloped outline harmonizing with the scalloped outline outside thereof.

What I claim is—

1. The design for a watch-case herein shown and described, the same comprising the circular lid B, the shield-shaped figure D, bordered by the connected series of raised scallops C C C, the contour of the latter being within the contour of the lid, as set forth.

2. In the design for a watch-case herein shown and described, the centrally-set shield-shaped figure D, having upon its outer periphery a scalloped outline, as set forth.

16. FOR A CAVEAT.

To the Commissioner of Patents :

Be it known that I, A. B., a citizen of the United States, residing at L., in the county of M., and State of N. jor subject, etc., see Rule 202], having invented an improvement in velocipedes, and desiring further to mature the same, file this my caveat therefor, and pray protection of my right until I shall have matured my invention.

The following is a description of my newly-invented velocipede, which is as full, clear, and exact as I am able at this time to give, reference being had to the drawing hereto annexed.

This invention relates to that class of velocipedes in which there are two wheels connected by a beam forming a saddle for the rider, the feet being applied to cranks that revolve the front wheel.

The object of my invention is to render it unnecessary to turn the front wheel so much as heretofore, and at the same time to facilitate the turning of sharp curves. This I accomplish by fitting the front and the hind wheels on vertical pivots, and connecting them by means of a diagonal bar, as shown in the drawing, so that the turning of the front wheel also turns the back wheel with a position at an angle with the beams, thereby enabling it easily to turn a curve.

In the drawing, A is the front wheel, B the hind wheel, and C the standards extending from the axle of the front wheel to the vertical pivot E in the beam F, and D is the cross-bar upon the end of E, by which the steering is done. The hind wheel B is also fitted with jaws G and a vertical pivot H.
