MEAT-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 694,951, dated March 11, 1902. Application ined reti-nary 20,1901, saturo. 43,036. cromati.)

To all whom t may concerne:

Be it known that I, J AooB EMIG, a citizen of theUnited States, residing at Buffalo, in the county of Erie and State of New York, have Y invented new and useful Improvements in Meat-@hopping Machines, of which the following specification, taken in connection with the accompanying explanatory drawin gs,will fully and clearly disclose the invention, so as to enable others skilled in the art to which it pertains to make and use the same.

This invention relates to that class of meatchopping machines in which a horizontallyrevolving chopping-block is used in conjunction with vertically movable choppingknives; and it has for its object the production of a practical, durable, and effective device particularly applicable for kitchen use and also to improve the mechanical construction, arrangement, and combination of the several parts; and to this end it consists in "the detail construction and arrangement of the parts, all as hereinafter more fully described, and pointed out in the claim. n

Inthe drawings, Figure l is a front elevation of my improved meat-chopping machine. Fig. 2 is a vertical section taken on line 2 2, Fig. l. Fig. 3 is a vertical section taken on line 3 3, Fig. l. Fig.v 4 is a horizontal section taken on line e l, Fig. 3. Fig. 5 is a horizontal section, on an enlarged scale, taken on line 5 5, Fig. l. Fig. 6 is a horizontal section, on a still further enlarged scale, taken on line 6 6, Fig. 1.

Referring now to the drawings in detail, like letters of reference referto like parts in the several figures.

The letter A represents the stationary table, which is supported by standards B, connected together at their lower ends bya bedplate C, which latter is secured to a base D, constructed of wood or any other suitable material. Said table, standards, and bed-plate constitute the framework of the machine and support the operating mechanism.

E designates a revoluble table having two concentric bearing-ribs e formed on its under side, which are smoothly finished or machined and which coact with two concentric bearing-ribs a, formed on the upper face of the stationary table, said bearing-ribs also being machined to make a perfect bearing between the stationary table A and the revoluble table E. Oil-ducts e' are formed in the table E, through which oil is passed to lubricate the machined faces of the bearing-ribs, and thereby reduce friction. A bushing Fv is passed through the stationary table A and is screwedinto the revoluble table Eto turn with the same, it being provided with an an- 6o nular flange, which bears against the under side of the stationary table and holds the revoluble table in position on the same. This bushing serves as a guide for the vertically-reciprocating rod, as will presently appear, and when worn can be unscrewed and replaced by another bushing.- By this construction a perfect-fitting guide can always be had at a slight cost and withoutreplacing other parts of the machine and aperfect ver- 7o tical movement given to the knives without A lateral sway, thus. assuring even contact of the chopping-knives with the chopping-block at every point of their cutting edge.Y

G designates the chopping-block, and G the curbnor casing, secured thereto by means of screws g or in any other suitable manner. This curb or casing extends below the lower surface of the chopping-block and has inverted- L- shaped slots H formed therein at 8o diametrically oppositepoints, which receive pins H', projecting from the sides of the revoluble table at points'coinciding with the position of the slots H. It is therefore apparent that the chopping-block and its curb or casing can be readily disconnected from the revoluble table to facilitate cleansing.

To the operating-shaft I, which is journaled in the framework, the fly-wheel J is secured, the latter being equipped with a handle J 9o whereby thel machine is operated. The gearwheel K is secured to the shaft I and meshes with a pinion K', secured to an auxiliary or counter shaft L, also journaled inthe frame-l Work below the operating-shaft I. This shaft has a grooved cam M secured thereto, which operates a cam-lever M', pivotally helden the operating-shaft land which is equipped at its upper end with a pawl m, pivotally secured thereto and adapted to engage the' ratchetroo teeth e', formed on the upper face of the revoluble table at its circumferential edge. A spring M2 is secured at one end to the lower end of the cam-lever M and at its other end to the base D, its purpose being to keep the lower end of said cam-lever against the camv and cause the pawl secured to its upper end to ride back over the ratchet-teeth, the cam giving the paWl mits stride or push to revolve the table. On revolving the counter-shaft the cam is revolved also and causes the camlever to oscillate on the operatingshaft,which causes the paWl m to engage the ratchet-teeth and intermittently revolve the choppingblock, which is securedto the revol uble table.

N designates a vertically-reciprocating rod which passes through a guide N', formed on the framework, and fn designates a guide pin or screw which is screwed into the guide to enter the longitudinal groove N2, formed in the rod N, the purpose of said groove being to prevent the turning of the rod. This rod passes upv through the bushing F, which guides the same, and also through a tube o, secured in an aperture formed centrally in the chopping-block. The tube o serves as a curb to prevent particles of meat from passing down through said aperture. The upper end of the reciprocating rod is reduced in diameter and carries a cross-head P, secured thereto by a To this cross-head verticallyadjustable chopping-knives R are secured, the adjustment of the same to the choppingblock being effected by the vertical adjusting-screws r, which pass through the crosshead and bear against the upper edge of the knives, Which latter are held in their adj usted position by thehorizon tally-disposed bindingscrews i, passing through the cross-head, and

the vertical slots fr?, formed in said choppingknives.

To the end of the counter-shaft L a crank S is secured, which is pivotally connected by a crank-pin s to a pitman T, also pivotally connected at its opposite end to an adjustable collar T', secured to the reciprocating rod N by aset-screw V, The chopping-knives may be adjusted to the chopping-block by raising or lowering the collar T on the reciprocating rod, as the case may require; but for a ne adjustment, which may be necessary When the chopping-block or the edges of the knives are Worn uneven, the adjustingscrews r must be resorted to. l

Having thus described myinvention, what I claim isv In a meat-chopping machine, the combination with the framework, of a stationary table secured thereto, a revoluble table supported on said stationary table, a bushing passing through said stationary table and having a ange bearing against the under side of the same, said bushing entering the revoluble table and bein g held therein bya screw-threaded connection, a chopping-block secured to said revoluble table, a reciprocating rod guided in said bushing, chopping-knives carried on said rod, and mechanism for operating said rod and revolving said revoluble table, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

JACOB EMIG.
