SLICING-MACHINE.

Application iii-ed November '10, 1919.

To @ZZ iciom t 'may concern Be it known that I, Sonoiirox VILE, a citizen of the United States, and resident .of Rochester, in the countiv of Monroe and State of \lew York, have invented certain new and useful improvements in Slicing- Machines, of which the following is a specification.

The present invention relates to slicing machines and more particularly to the type in which a rotary knife is employed in connection with a table movinpf` transversely of the turning axis of the knife, an object 0f this invention being to provide an improved means through which may be effected a relative movement between the table and the knife in the direction of the axis of turning. Another object of the invention is to provide a novel feeding mechanism for feeding the knife in the direction of its axis. fi. further object of the invention is to provide an automatic means which will effect a. relative movement between the knife and the work support in the direction of the axis of the knife.

To these and other ends, the invention consists of certain parts and combinations of parts, allL of which will be hereinafter described, the novel features being pointed out in the appended claims.

Fig. 13 is a detail view of thc means for holding the material upon the support. Referring more particularly to the drawings, i indicates the frame of the machine which may be secured to any suitable supporting member suoli as a board 2. This frame embodies in this instance, two side members and carries a support 3 for the 1na terial to be sliced, and a rotary cutter d which preferably is in the form of a cutting disk with a peripheral cutting edge. The cutter and the work support are so formed that the work support may move transversely of the turning axis of the cutter while provision is made whereby a relative movement between the cutter and the support in the direction of thc axis of the cutter may take place. In this embodiment. this relative movement is effected by moving the cutter in the direction of its axis` but it will be apparent from some points of view. that the invention is not limited to producing this relative movement by a movement of the cutter.

In order that the support for the material may partake of its movement transversely of the axis of the cutter, this support may have two guides 5 preferably on its under side and secured at opposite ends in blocks 6. These guides, in this instance, travel in bearings T formed at the upper ends of the frame pieces, the blocks 6 cooperating with the side pieces to limit the movement of the support for the material in its two directions of movement.

The cutter 4 is preferably secured to a shaft 8 which connects to two frame pieces l and has a rotary as well as an axial movement in said frame pieces. This shaft may be provided with a screw 9 and on this screw a nut or internally threaded sleeve lil may operate. This sleeve is held against axial movement in fin v suitable manner as in the manner hereinafter described.

It is apparent that if the shaft is permitted to turn freely in the nut` the shaft will move axially whereas, if the nut is locked to the shaft, the nut will turn and at he same time the shaft will be held against axial movement. In order to effect this con nection and disconnection of the nut with the shaft. a breakable connection is provided which in this instance consists of i.

sliding key 11 movable in a longitudinal extending groove or way 12 in the shaft and adapted at one end to enter into a notch or opening 13 in the nut. For the purpose of operating this key, the latter has a collar 14 rigidly secured thereto and surrounding the shaft 8. rIhis collar is acted upon by a helical spring 15 which surrounds the shaft and abuts the sliding collar 14 at one end and at its other end a collar 1G is rigidly and adjustably secured to the shaft 8 by a set screw 1T. The spring normallv holds the key ll in connection with 'the nut 1d. in order to effect the disconnection of the nut with the shaft so as to permit the shaft to turn in the nut, the collar 14 may be provided with an annular groove 20. ln this groove a yoke 21 operates, said yoke beg ing secured to the upper end of an arm 22 which at its lower end is pivoted at to the supporting base 2. An arm 24 extends late ally from the lower end of the arm 22 and upon the depression of the arm 24th@ collar 14 will be moved to move the key 11 out of connection with the nut. Automatic means may also be provided for breaking the connection between the nut and the screw shaft, one embodiment of such means being hereinafter fully described. l

Any suitable means may be employed for moving the support 3 for the material to be sliced transversely of the axis of turning of the cutter shaft. In this'embodiment, this support movement is produced through a connection with the cutter shaft and to this end the nut 10 is provided on its periphery with teeth Q5 which cooperate with upwardly presented teeth on a rack QG, this rackbeing suspended by brackets 2T from the under side of the support 3. it is apparent that rotation of the shaft S yhv any suitable means such as a crank handle 2S, when the nut 10 is interlocked with the shaft, will'produce a movement of the support transversely of the shaft through the rack 26 and the gear teeth 25. The rack bar 26 is utilized for preventing` the axial movement of the nut 10 and to this end, the nut is provided with annular flanges 10a on opposite sides of the teeth 25, these flanges cooperating with opposite sides of the rack bar to prevent the axial movement. Beneath the rack bar at a point directly below the nut, one of the frame members may be provided with a proj ecting portion 29 which cooperates with the under side of the rack bar to maintain cooperation between the rack bar and the teeth 25.

lith the end in view of effecting the automatic shifting of the cutter shaft in the direction of the axis of said shaft, the suptance between the collar 14 and the nut 10 when the collar is in the position to hold the nut so that the shaft is interlocked therewith, whereas, the thickness of the latchor detent in rear of said tapered portion is greater than the distance between the collar 14 and the nut 10. rIhe pivoted latch or detent 30 is so arranged on the support that when the latter has reached one end of its movement, the tapered end will pass between the collar 14 and the nut 1() and move said collar in the direction of the axis of the shaft S so as to break the connection between the shaft and the nut, permitting the shaft 8 to turn in the nut and in this way move the cutter axially toward the support 3 for the material. ln this embodiment, the shaft 8 makes only one rotation before the interlocking connection between said shaft 8 and the nut 10 is restablished. This restablishment is effected in this instance by projection 33 on the face of the collar 14 opposed to the nut. The Vprojection engages the under side of the latch 30 and moves said latch upwardly in the manner shown in Fig. l2, out of the position between the collar 14 and the nut 10, after 4which the spring 15 will move the collar 14 so that the key 11 will reestablish connection between the nut 10 and the shaft 8. The dog or latch being wider than the distance between the collar 14 and the nut 10, will rest upon these parts so that, when the shaft is rotated in a reverse direction, the dog will be carried away from such parts to Vthe other extreme movement of the support 3 to again separate theY parts upon the next approach thereto. 1n order to limit the axial movement of the shaft in two directions, two stops 34 and35 are provided, one of these stops cooperating with the collar 16 andthe other stop cooperating with a collar 36 on the shaft, both stops being in the form of screws and being adjustable. v

The material may be held on the support 3 in any suitable manner. It is preferred however, to provide the upper surface of the support with a plurality of projections 37 and'to mount on the support, a plunger 38 having a clamping head 39 at its lower end and a handle 40 at its upper end by which the clamping head may be elevated against the action of the spring 41 which surrounds the plunger 38. The plunger 33 may be guided in a bracket 42 which is supported from the support 3. The operation of the invention will be understood from the foregoing, but it may be summarized as follows:

The meat or other material is secured upon the support 3 under the clamping head 39 to project beyond the support 3 in the path of the cutter 4. The crank handle is then turned which moves the support 3 transversely of the cutter shaft 8 and causes the rotary blade 4 to slice the material on the support. Upon the return movement ofv -in the opposite direction another slice will be cut from the material. This operation is continued until the knife or critter 4 approaches the proximate edge of the support 3. lWhen this position is reached, the lever arm 24 is depressed, shifting the collar 14 to break the connection between the shaft and the nut l0. The shaft is then turned in a direction to cause the cutter or knife t'o be moved away from the support 3 and, when the desired position of the knife is reached, the lever 24 is released permitting the connection between the shaft S and the nut to be restablished.

lrom the foregoing it will be seen that there has been provided a rotary cutter movable axially and combined with a support for the material to be sliced movable transversely of the axis of rotation of the cutter. A driving connection is provided between the shaft of the cutter andthe support, this driving connection preferably being breakable so that the shaft may be moved axially independently of the support. Means is also provided whereby the cutter shaft may be moved automatically when the support reaches a certain position. This automatic means is preferably in the form of a dog carried by the support and coperating with the breakable connection.
