SPECIFICATION forming part of Letters Patent No. 240,547, dated April 26, 1881.

Application filed July 29, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE RIEsEcK, of

Allegheny, in the coun tyofAlleghen y and State of Pennsylvania, have invented certain new and useful Improvementsiii Meat-Choppers; and I do hereby declare the following to beafull,c1ear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in meat-choppers; and it consists, first, in placing the boxes for the cranked driving-shaft 1 5 upon a vertically-movable rod, and guiding the boxes in their movements by means of slots in the frame, and attaching the pitmen for operating the cutters, and the valve-rod to the cranked shaft, so that when the shaft is raised upward the machine will be stopped; second, in the combination of the cranked shaft having a vertical movement, the pitmen which operate the cutters, the valve-rod and valve, which are operated by the shaft, a valve for controlling the admission of steam to the steamchest, and which valve has a rod attached to it for passing up through a frictional stuffingboX, with the tub, cutter, and frame, third, in the combination of the cranked shaft, which is journaled upon a vertically moving bar, connecting-links, and levers which are pivoted together at their inner ends and to the frame at their outer ends with the pitmen, cutters,

and tub; fourth, in the arrangement and com 3 5 bination of parts, which will be more fully described hereinafter, whereby the driving mechanism is thrown in and out of gear with the revolving rack upon which the tub is placed.

The accompanying drawings represent my invention.

Figuresland2 are side elevations of myinvention. Fig. 3 is an inverted view of the same. Fig. 4 is a vertical section taken through the frame. Fig. 5 are detail views of the valves.

4 5 Fig. 6 is a side elevation.

The frame A consists of the standards a, braced by I), cast with the former, having braces 11, b and 11 between them.

Between the sides of the frame A, near the '50 bottom, are the horizontal braces d, which support the meat-block B upon rollers in advance of the standards a.

Under the block'B, and attached thereto, is a rack, 00, that is engaged by a pinion, D, rotated by a pulley, E, on the end of its shaft, outside of the frame A. The shaft of this pinion moves in a sleeve, 6, to which a lever, f, whose fulcrum is on the inside of the frame A, is attached. The handle of the lever f extends forward, and if depressed raises the sleeve and pinion, engaging thereby the rack under the meat-block; but when raised up it throws the pinion out of gear, whereby the rotation of the block is stopped. Between the lever f and the inside of the frame A is the guide as, with shoulders that limit the up or down motion of the lever; and pivoted on it is a dog,g, which, when the lever is depressed and the pinion in gear with the bevel-wheel, catches on top of a triangular block, it, near the handle of the lever, and prevents it from rising; but when the pinion is thrown out of gear, by raising the lever the dog catches under the block h and secures it in that position. By this means the meat-block may, for any purpose whatever, be stopped, turned back or forward, and again set in motion by hand while the engine is running.

In the standards a, between the braces b and 15 are slotsi, in which rest the ends of a flanged bar, 0, and under the slots, 'at the inside of the standards, are vertical guides K,in whichthe ends of the flange under the bar Gare confined. On top of the bar, at its ends and in the middle, are pillow-blocks N, in which the crank-shaft F is journaled. The ends of the. crank-shaft protrude beyond the standards a, and on one of them is a belt that runs the pulhey E, and on the other is the fiy-wh'eel G.

Thepitmen w on the crank-shaft are rigidly attached by wrists to vertical rods Z, that have their lower guides on a brace, m, between the standards, and at their upper ends to the slides a, in front of the upper cross-piece connecting the standards.

From the attachment of the pitmen to the vertical rods lforward, extend the-arms at a right angle with the rods. The arms are supported by braces attached to the slides n, and to or near the outer ends of the arms p, 100

thus forming a rectangular triangle over the meat-block. The knives H are adjustably attached to the forward ends of the arms 1), and

are raised or depressed by the rotating crankshaft.

One (or both) of the rods 1 is prolonged upward beyond the slides a, and acts as a pistonrod to the steam-cylinder P, placed on top of the upper brace, between the standards a.

At the side ofthe cylinder is a steam-chest. S,into which enters,from below, the valve-stem U,joined to a cam-rod on an eccentric of the crank-shaft F. The valve-stem U operates the slidingvalve within the steam-chestin the usual manner.

Steam is admitted into thechest through a valve, q, attached to the chest, which valve is operated by the rod 0), that is brought in contact with it when the crank-shaft is lifted up from its ordinary position.

On top of the valve (1 in the valve-chamber is a rod, 1, which passes out through a stuffing-box, and holds the valve when it has been pushed up by the rod underneath the valve in that position. The steam is shut off when the valve "is pushed up, and the friction on the rod in the stuffing-box keeps it from reopening itself, and will have to be pushed down by hand to read mit steam.

The valve q, with its rod 1", may be placed in nected with the crank-shaft are raised up and the valve admitting steam is closed. Thus the machine is brought toa standstill, when a continued motion would unavoidably cause some of its parts to be broken.

To prevent an oblique o r unequal motion of the bar 0 when only one of the knives meets an impediment, a pair of links, t, are jointed to the flange under the bar, which links form fulcrums to two levers, J, that are pivoted to the insides of the standards a. The ends of the, levers meeting at the middle, under the bar O,'are joined together, and by this device the motion of the bar, be it rising or falling, is made to be always horizontal.

The object of my invention is to prevent oil, grease, or dirt, from falling on the meatblock and being chopped with the meat, by placing all parts of the machinery employed to operate this meat-chopper away from over the meat-block. Many of the meat-choppers now in use have a great part of the working machinery immediately over the meat-block andknives,anditis consequently nexttoimpossible to prevent things from becoming mixed in with the meat that should be kept separate from it. The automatic action of the valve, whereby the steam is cut off at a moment when continued motion would inevitably cause some part of the machine to be injured, I also consider of importance. An advantage is furthermore gained by the use of the lever and dog, since by stopping the rotating block access to it is obtained, whethcrto clean its surface or for other purposes.

Having thus described my invention, 1 claim 1. In a meat-chopper, the combination of the frame provided with guiding-slots, the crank-shaft having its ends journaled in boxes which move in slots, the bar (J, having the boxes or bearin gs for the shaft secured to its top, the pitmcn for operating the cutters H, the slide-valve, valve q, the operating-rod 'v, and the tub in which the meat is cut, substantially as shown.

2. In a meat-chopper, the combination of the cranked shaft F, having a vertical movement, the pitmcn w, for operating the cutters, and the valve-rod 11, attached to the shaft, with the valve q, rod r, and stuffing-box, tub. cutters, and frame, the parts being combined to operate substantially as described.

3. In a meat-chopper, the combination of the links t, levers J, pivoted to the'frame at their outer ends and to each other at their inner ends. with the vertically-moving bar 0 and shaft F, mounted thereon, pitmcn, cutters, I00 and tub, substantially as set forth.

4. In a meat-chopper, the combination of a revolving rack upon which the tub is placed, the pinion D, placed on the same shaft as the driving-wheel E, with the sleeve 0, lever f, dog g, and guide 00, substantially as shown.

In testimony that I-claim the foregoing I have hereunto set my hand this 24th day of June, 1880.

GEORGE RIESEOK.
