This invention relates to meat slicing machines of the general type disclosed in my copending applicati n, SBI ial No. 129,325., filed August 16, 1926, and directed to means for receiving and assembling the slices as they are formed by a machine for slicing meat an oth mat r a nd has f r it bjec he pro is on a su a d ce which hall e o improved construction and operation; which shall be Simple and economical to manufacure; which sha l r quire a minimum a un of power to operate; and which will assemble the slices in a stack suitable for wrapping. The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed in the appended claims.

The numeral 10 designates the frame of a slicing machine having the usual reciprocating table 11 mounted on a guide bar 12 and movable pasta rotary slicing knife 13 for presenting the material to the knife to be sliced. Projecting forwardly from the base 10 is a bracket 15 having a perforation 16 therein for holding bearing bushings 17 and 18 which are fined therein. A spider 19 is journaled on upwardly projecting portion of the bushing 18 while the bushing 17 is j ournaled in a bracket 20 secured to the spider 19 by screws 21 and extending downwardly below the lower face of the bracket 15. The

bracket 15 is, provided'with a. recess for receivingav ratchet wheel 22 inte pos d b t en he ends off-the bu hings 7 an 18- A spring detent 23 engages the teeth of the ratchet wheel 22 to hold it against rotation in one direction and a second pawl 24 is carried by a sleeve 25 mounted in the bracket 20 and engages the ratchet wheel 22 to rotate the ratchet wheel when the spider 19 is rotated in a counter-clockwise direction, as Viewed in Fig. 2. A screw 2.6 extends through the openings in the bushings 1 7 and 18and is provided with a flange 27 at its lower end to limit rip ward movement ofthe screw. A ball 28 is carried in a sleeve 29 in the ratchet wheel 22 and engages the threads of the screw 26. The

ball 28 is held in yielding contact with the threads of the screw 26 by a spring '20. The spider 19 is connected to the reciprocating table 11 by means of a connecting rod 31 having one end pivoted to the spider at 32' and the opposite end carried by a ,d owhwardly projecting pivot pin 33 mounted on a bracket 34 secured to the end oi the reciprocating table 11 by screws It will be apparent from Fig. 2 that reciprocation of the table 11 will be transmitted to the spider which will reciprocate about the axis of the screw 26.

The edge of the spider 19 adjacent the ma chine frame is curved about the axis of the screw 26 and is provided with an upright plate 36 which extends upwardly to a posi tion just below the edge of the reciprocating table 11. The ends of the plate 36 are continued forwardly in straight portions 37. The upper end of the screw 26 carries a horizontal plate 39 fixed to the screw 26 and shaped to iit'within the contour of the plate 36. The shape of the plate 39 fitting within the plate36 constrains the screw 26 'tooscillate in unison. withthe spider 19. It will be seen from Figs. 2 and 4 that when the table 11 moves forwardly on a cutting stroke the spider 19 will bemoved in, a counter-clock.- wise direction and will carry the ratchet 22 with it, the ratchetteeth moving idly over the detent 23. There will be no relative movement between the ratchet wheel and screw 26 at this time since they all travel in unison with one another. During thereturn movement of the feed table and spider.19, however, the ratchet wheel 22 will be held against reverse rotation the detent 23,. while the pawl 24 will ride idly over the teeth of the ratchet wheel. This will permit the screw 26 to rotate relative to the ratchet wheel 22 and impart a downward movement to the screw. l/Vhen the screw 26 reaches its lowermost position the ball 28 will register with a circum ferential notch 40 so that further reciprocation of the spider 19 will not afiect the verti cal position of the screw. The threads of the screw 26 are rounded so that the ball 28 will yield when upward tension is exerted on the knob 41 at the top end of the screw. This makes it possible to return the plate 39 to its uppermost position by lifting the knob 41 with suflicient force to overcome the resistance of the ball 28.

A slice deflector 42 is secured to an upright post 43 which is swiveled in a bracket 44 con nected to the chain box 45 of the slicing machine. The inner edge of the deflector 42 bears against the beveled face of'the knife 13 closely adjacent the edge of the knife. The

deflector is yieldingly held in its operative position by a spring 49 secured to the bracket 44 by cap screws 50. against a squared face of the post 43 and when outward force is exerted on the deflector 42 it may be swung away from the knife 13 and the spring 49 will engage the side 51 of the post 43 and hold the deflector in its.

open position, thus permitting cleaning of the knife and deflector. It will be seen from the drawings that the operative face of the deflector is provided withcorrugations forming limited contact lines for engaging the slices. The corrugations are provided with narrow edges forming substantially line contacts with the slicesas they move away from the slicing knife.

A slice support 54 is arranged adjacent the edge of the reciprocating table 11 in position to support the projecting portion of the material which is severed by the knife 13 to form the slice. The support 54 is carried by a bracket 55 which is fastened to the top of the base 10 by screws 56. A projection 57 extends outwardly from the support 54 adjacent the cutting edge of the knife 13 in position to support the slice as it passes away from the cutting edge. A projection 58 is formed at the bottom edge of the deflector 42,

the projection 58 being slightly below the top face of the support 54 and in position to receive the lower edge of the slice as it moves away from the projection 57 It is found de sirable to have the projections 57 and 58 spaced a slight distance from each other to prevent any material which is drawn downwardly by the knife 13 from being held between the projecti-ons. The projections should be sufliciently close together, however, to form a substantially continuous support for the lower edge of the slice. 7

Resting on top of the plate 39 is a slice supporting plate 60 which is curved to con- This spring bears form to the curvature of the upright plate 36 and is inclined forwardly so as to support the slices, as they are formed, on edge in an inclined position. The plate 60 is arranged to move forwardly at the same time that the plate 39 is fed downwardly so that the plate 60 is given both a downward and forward movement to accommodate the additional slices as they are deposited against the inclined face of the supporting plate. The plate 60 is provided with abottom web 61 which rests on the plate 39 and may be held in position by a screw 62 which travels on a slot 63 in the plate 39. The end portions 37 of the curved plate 36 are provided with inclined slots 64 and the ends of the plate 60 are provided with studs 65 projecting through the slots 64. Rollers '66 may .be mounted'on the studs 65 to reduce the friction of the studs in the slot 64.

At the beginning of a slicing operation, the parts are in the position shown in Fig. 3. As

the machine is operated, the first slice is de-. posited on the inclined face of the support 60, being directed against the face by the deflector 42. The lower edge of the slice will the slice as it is deposited upon the supporting plate 60. During the return movement of the table 11, the plate 39 Willbe fed downwardly by the ratchet and screw mechanism, previously described. The downward movement of the supporting plate 39 will cause thestuds 65 to travel in. theinclined slots 64 so that the plate 60 will be drawn forwardly away from the upright plate 36 at thesame time that the plate 39 is moved downwardly. This will provide space for the succeeding slices formed by the next operation. As the successive slices are formed, they will be deposited with their broad sides against one another and will be held in inclined position by the plate 60, will be supported by the plate 39, and held from displacement by centrifugal force by the plate 36. When it is desired to return the plate 39 to its upper position, it is only necessary to lift upwardly on the knob 41 and the plate 60 will be automatically moved toits initial position shown in Fig. 3 as the plate 39 is restored to its uppermost position. The end portions 37 of the plate 36 are in position to hold the slices from sliding on the receiving table when the diis reversed.

In place of theslice support 60, it may sometimes be found desirable to use an inclined slice support having ribs or other means for preventing curling of the slices.

This is especially desirable for some grades of bacon, the slices of which have a tendency to roll or curl. Such a device is shown in Figs. 4 and 5. A metal plate is shaped to fit over the plate 39 and is provided-with a cap 7l'which fits down over the knob 41. It

will be understoodthat the plate 60 is not used when the plate 70 is employed. The plate 60 may be readily removed by loosening the screw 62 and lifting the plate 60 off of the plate 39. The plate 7 0 is provided with fins or ribs 72 which are cut from the body of the plate and bent into upright position, as indicated in the drawings. The top edges of the ribs are preferably inclined so that the ribs are higher near the center than they are adjacent the periphery of the plate 70. When-the plate 70 is in place on the plate 39, it, of course, will rotate with the receiver 39 and will be fed downwardly but will not be fed horizontally. It will be understood, of course, thatthe plate 'TO-might be mounted in a manner similar to the plate'60 to provide for horizontal movement,or, what is the same thing, ribs similar. to those shown at 72 couldbe provided on the plate 60; In'operati'on, the slices will be deposited on the edges of the ribs 72 and if there is a tendency for the slices to curl, they will be caughtby the ribs 72 and curling prevented.

The inclination of the receiving surface formed by the-ribs 72 permits-the slices to take a curved position conformingsom'ewhatand lift the stack by raising the plate 70.

They may then be dumped from the plate onto the wrapping paper without the necessity of touching the slices.

The receiver shown in'Figs. 6 and 7 is similar in operation to that shown in Figs. 4 and 5, but its construction is slightly different. In Figs. 6 and 7. a strap 73 forms the periphery of the receiver and this outer strap or band is connected'by rods 7% to the central cap 75 which corresponds to the cap 71 in the form shown in Figs. 4 and 5.

That portion of the forward end of the first slice which overlaps the first rib contacting with the slice, hangs downwardly somewhat over this rib, and this rib can therefore exert a positive pull onthe slice to straighten it out when the receiver moves faster than the meat table. The remaining ribs could therefore be omitteda'nd the slice rearwardoi the part overlapping the rib permitted to rest on a plane rece1v1ng surface. However,

I find it more desirable to support the entire slice on aseries of ribs so perfectlystraight.
