turned serrated inneredge 36 is removably The meat or other material to be cut is adapted to be placed upon this tray.

The carriage is provided with a pair of arms 37 extending upwardly either side of lthe plate 32 and pivotally mounted in the upper ends of these arms above the plate are the bell crank arms 38, the inwardly ex tending' members of which are providedwith pivotally serrated gripper members 39.

The outer and upwardly extending members of thebell cranks are connected Aby a link 40 and a lever 41, the link being connected to the lever intermediate of `its length. When the lever is thrown inwardly both o f the bell crank members swing outwardly thus throwing the inner members carrying the grippers away from the table to allow the placing of the meat to'be cut.

Thel bell crank members are provided with spiral springs 42 which tend to force the gripper membersdownwardly to hold the meat securely in place.

The carriage is provided with a downwardly extending arm 43 inwhich is pivotally supported an arm 44 carrying a pin 45 projecting downwardly to engage a spirally threadedfshaft 46 extending longitudinally thereunder. The rotation of this shaft moves the carriage forwardy as the knife moves clear of the material to be cut. The shaft is operated by a pair of clutch memsection in Figure V7.

The form of clutch shown is of the ball type, the spring held balls'49 engaging the cone 50vwhich is' Vsecured to the shaft. The

' clutch 47 is adapted to grip and hold the shaft from backward rotation, it being held in a stationary position by the rod 51 illustrated in'Figure 3 or the rod 52 illustrated in Figure 6. This clutch member is provided with a pin 53 extending toward the member 48 and the member 48 is provided with a pin 54 adapted to engage the pin 53.

In the mechanism illustrated inFigure 3y l'the clutch 48. has connected to its outer side a bar 55 which extends upwardly and is pivotally connected to a bar 56 extending rearwardly and pivoted .to the casing 2.

The arm 14 is provided with a pin 57 on.`

its inward side` which is adapted to engage the underside of the bar 56 t o lift it following the backward swing of the knife arm and on being lifted the movement is transmitted through the rod 55 to turn the clutch 48 to grip the shaft and turn it, thus through the worm and pin construction described, advancing the carriage.

The degree of advance is regulated by the

rods

51 and 52 to bringthe pin 53 on the clutch v47 vinto such a position as to engage the pin 54 to limit the return movement of the clutch 48. This adjustment can be regulated so that the feed shaft may be turned a very slight amount in orderto produce a very thin slicing or may be turned to any degree to produce an extra heavyV slice. Y

l.The adjustment of the rod 51 is eected through a thumb lnut 58 but a more deinite karrangement of graduation may be effected by means of a quadrant lever 59 as illustrated in Figure 6. l

' In the construction shown in Figure 6 the clutch 48 is operated by a link 60 connected to an arm 61 pivotally mounted within the casing and engaged by a roller. pin 62 mounted on the spur gear 8. The pin being mounted on the spur gear will operate with a smoother action than will the mechanism operated by the pin on the swinging arm, which may be more desirable, and will not convey the shock incident to the other transmission.

In the operation of this machine the meat to be sliced is placed upon the tray 34 and the gripping levers are thrown down, the springs holding the gripper members in flexible contact therewith. They meat projects' beyond the grippers and beyond the tray and slides on the longitudinally corrugated plate 32 and is fed up to the knife.

The rotation of the hand wheel then revolves the knife through the train of gears described and as the spur gear 8 revolves the roller pin carried' therebyoperates the knife carrying arm to swing forwardly and as the carriage is Varranged considerably below the axis of the knife, the cutting will be effected mostly, if not entirely, below the centre and as the knife swings forwardly it also swings downwardly, thus making a downward cut which is most desirable as itV cuts toward the solid support of the carriage aid thus avoids cutting slices thick on one s1 e. Y

The knife feeds forwardly at a moderate rate of speed as the operating pin travels around the outer portion of the orbit of the spur' gear and following the completion of the forward movement, the pin moves inwardly toward the pivot and thus swings the knife back with an accelerated movefrom said base, a rotatable knife and means for rotatmg the knife, of an arm rigidly connected with said pivotal knife arm, a wheel Vlongitudinal slot therein, a gear wheel 4operating the knife rotating means and arranged in eccentric relation to the pivot of the knife arm, a pin arranged upon said gear engaging the longitudinal slot in said slotted arm, a casing enclosing said gear and slotted arm arranged at one end of said base,A
