turnover MEAT-enorme MAGHINE.

TO WHOM IT MAY CONCERN:

Be it known that ALFRED F. SPAULDING and SALMON M *Seor-r, of Winehendon, in the State of Massaohu. setts, have invented certain new and useful Improvements in Machines for Chopping Meat; and the following is declared to be a full, clear, and exact description of the same, reference being had to the accompanying .drawh ings, in whichl I Figure 1 is a top view of the machine with the tub-eover removed.

Figure 2 isa side elevation, and Figure 3 a. longitudinal vertical section of the same. Figure 4 is a transverse vertical section, taken through the shaft of the driving-wheel. Figure 5 is a like section of' the crank-shaft of the machine. The improvements which are the subject of this application relate chieiiy to the method ofA and means for Operating the cutters or knives of a'machine for chopping meat and other substances, and they consist inl-- First, the employment, insuch a machine, of one or more cutters, and their actuatingmechanism, when'k so arranged that the substance shall be cut witha draw cut, or by a drawing stroke of Athe cutters.

Second, the combination and arrangement'of mechanism for producing the necessary vibratory movement of the cutters, and for adjusting said cutters so as to regulate their stroke. V

Third,'rthe method of mounting the cutters in the machine. so as 'to enable them to yield to bones and other obstructions in the tub. l

Fourth, the combination, with the tub, of a removable cover.

AIn order to produce the draw cut, the vibratory cutters or knives are arranged so that they shall move dingonnlly,'or yin avcurvilinear path, towards lthe substance'to beichopped, .thus avoiding the up-and-downpounding action of the cutters -of ordinary machines. The substance is thus vminced or cutup much more eEectively and thoroughly than can otherwise be accomplished, and the time consumed in the operationY is greatly shortened.

vTo enable those skilled in the art to understand and usethe invention,the manner in which the same isA or may be carried into ell'ect will now be o lescribedr v In the drawings, A denotes the bed-plate of 'the machine, which-'may be constructed of wood, cust` iron, or any suitable material. To the upper face of the said plate,`and near'one end thereof, two curved posts or stands. ards, B, are secured, and extend upward at right angles therefrom, and have the form as shown 'in figs. 1 undA 2; Through holes a a, ymade through the front ends of the. said standards, ay shaft or rod, C, extends horizontally, and serves as a fulcrum for the two knife-carriers in levers D D, which areA so applied thereto as to be capable of having vertical movements -imparted to them by means of two connectingrods, E E, which are respectively hinged or jointed to or nearto the middle of the said carriers DD, as seen ings. 1 and 3. On the rear end of each of the levers D D, a tubular socket, e, is made, the same being for-the .reception ofthe ahanks b b of two adjustable knives or cutters, G G, formed las shown in Figure 6, (which is a. side view of one y of such cutters.) Each of the cutters Gr should be so formed and applied to its carrier that its cutting-edge, when brought into its lowest position, 'shall almost touch or be nearly in the same horizontal plane with the top surface of the bottom of the tub E in which the knives work. The said knives are made adjustable with respectto the bottom of the tub by means of pins ff, which pass through holes made through the sockets c a, and a series of holes, o o, nitide through the shanksofA the knives, (one series of such holes being shown in iig. 6.) Furthermore, the said knives are so arranged that when in operation their cutting-edges move in a curvilinear path, and thus are caused to act upon the meat or article to be chopped with a drawing stroke..

In order to prevent any injury to the knives or other part of the machine, in case any hard or lunyielding material should get between the edge of either knife and the bottom of the tub, a short tubular cylinder, 11, of Indio. rubber, is placed around each of the journals of the shaft or rod C, in manner as shown in Figure 47, (whichis a longitudinal section, taken through the shaft and its bearings.)

being chopped. i

The tub E is of a cylindrical form, and has a diameter a little less thandouble the lengthot' the cuttingedge of either of the knives, inv order that as the -tub is revolved every portion of the material to be chopped shall be brought under the action of the cutters.r l The said tub is supported upon an annular frame, I, having l the form as shown in Figure'S, (which is a top view of such frame.) On the nppcr surface of the said frame,

four or any other suitable 'number of projections, g g, are disposed,fand bear against therchnes 'of the tub,

andare for th'e'purp'ose of holding rthe tub on the `frame while the tub may be in revolution. Thefsaid frame is formed with or is supported by a vertical spindle or roll, K, which extends down through a.' slot'made through the bed-plate A, and is secured to the latter by a nut screwed upon'the lower end of the spindle, as seen in fig. 4. i Directly underneath the annnl'arpart of the frame I, and so as to work in Contact therewith, a rubber friction-wheel, L, is located, the same being laizredto said shaft, as seen in iig. 2. The said gear-wheel M engages with a pinion, o, mountedon one -eud ot' the vsecondary driving-shaft P, oil-which a balance-wheelrR, is arranged, as shown in figs; 1 and2; the object of this arrangement of the said wheel R being togive a uniform movement to the'cutters G G. rlhc saidshaft P vhas formedA upon and near its opposite end, two wrists or cranks, S S, to which the lower ends ci' the'connecting-rod's E are'rcspectively united. V is a crank or handle applied to the driving-wheel. By the application oi' a suitable motorV thereto, the machine maybeput in operation. W is a removable cover for retaining the meat within-the tub while suoli meat is in the act. ot'

By taking holdof the handle Y, and turning the driving-wheel or lpinion M, rotary motion may be imparted I to the`-drivingwheel shaft, andot'course to the fricticn-driving wheel L, which, in turn, will communicate a continuons rotary movement to the tub II.V ,'Ihe said. pinion M, at the same time acting on the gear o, also i gives rotary motion to the shaft P, andas thel connecting-rods which are attached to the knife-carriers are jointedrto cranks disposed inlopposite sides of the` said shaft, at angles of one hundred and eighty degrees from each other, reciprocating alternate movements will be imparted to the knives G G, in vertical planes, at cach revolution of thosaid shaft P.v

Thus it will be seen that laythe vabove-de'scri'ocd,peculiar construction and arrangement of the'parts ofthe machine, by simply putting. the driving-Wheel;iurevolntion, not only a continuous rotary motion is imparted to the tuband the contents thereof, but the knives are given-alternate vertical movements inthe arcs of' circles, whereby the said knives are made to operate to the vbest advantage (viz, with a. drawing stroke) upon `the meat or material tobe' chopped.' Furthermore, by ,giving` tothe tub a continuous rotary motion, every portion of the material to be chopped will be brought uniformly under Athe-action ofthe knives.

What is claimed as the invention'ot' the said ALFRED F. SPAULDING and SALMON M. Soo'rr, is as follows:

l. Theemp'loyrnent, in a'n organized machine for chopping meat, vegetables, and other substances, of a revolving'tub, and one or more-cutters, and 'actuating-mechanism, under an arrangement substantially as described, so that the` meat or othensubstance shall be cut with a draw cut, or by a drawing stroke of therk said cutters.

2. The arrangement of theirame, and methodjoi' hanging the cutter or cutters in said frame, so that, when operated, the cutters shall travel towards the bottom of the revolving tub in a curvilinear path, .substantially as herein described. l v i 3. AThe combinatiomiwith the cutter audits vibratory arm, and mechanism whereby it isl ,made to operatev with a drawing-cut, of the means foradjustin'g the cutter in said arm for the purpose of regulating the `stroke of the said cutter, substantially as set forth.

4. The method herein described, or its substantial equivalent, of mounting the vibratory arms ofthe cutters upon 'a padded pin, or sol that the cutters may yield to intervening obstructions, as herein set forth. l

5. The combination, with one or more vibratory cutters, and a tub, oi' a removable cover overlianging the tub, substantially as herein shown and described. y

6. 'A mahhine for cutting meat and other substances, composed of the following elements combined: first, a support for the tub, mounted on a central pivot; second, one or more cutters hung in such manner as to produce, when vibrated, a drawcutg third, a mechanism to impart vibrating motion to the cutters, and a. rotary movement to thetub.
