SLIGING-MAGHINE.

Specification of Letters Patent.

Patented Sept. 21, 1920.

Application filed March 21, 1919. Serial No. 284,037.

To all whomz't may concern:

Be it known that I, 'aurnn CHANDLER KNAPE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Slicing-Machines; and I do declare the followin to be a full, clear, and exact desoription of the same, taken in connection with the accompanying drawings, forming a art of this specification.

y invention relates to slicing machines, more particularly to that kind of slicing machines employed for slicing bread and the like, in which the material being sliced is y step by means of an intermittently rotated worm in the base of the machine beneath the guideway. The object of my invention is to provide means for protecting the worm from falling crumbs which interfere with its freedom of action. Another object of my invention is to provide a machine of this kind with an improved form of pusher which is freely movable from end to end of the chute without binding. More specifically the object of my invention is to provide a pair of arms for connecting the pusher with the worm which pass through a pair of slots provided therefor and so arranged that crumbs falling through the slots cannot by any possibility fall into the worm. To these and other ends my invention consists in the arrangement and combination of parts illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings;

Figure 1 is a side elevation of a slicing machine in which one embodiment of my invention is incorporated.

Fig. 2 is a plan view of the same, parts being sectioned away to more clearly show the construction of the chute and the pusher, and

Fig. 3 is a transverse section on the line 3"-3 of Fig. 2.

Similar reference characters refer to the same parts in all the figures of the draw- 1n T have illustrated a slicing machine embodying my invention which comprises a frame composed of end members 1 and 2 having hearings in which a shaft 3 is revolubly mounted. At its forward end the shaft 3 has a ulley or fly Wheel 4 secured thereto by whlch the shaft is driven either by a belt connected with a source of power, or manually by means of the handle 5. Adacent the base of the machine a worm 6 is revolubly supported in the frame members 1 and 2 and atits forward end has a clutch member 7 secured thereto. A cooperating clutch member 8 is reciprocated by means of the rod 9 enlargwl at its upper end to form a ring 10 which is seated on an eecentric secured to the shaft 3 to rotate there with. A thumb screw 11 is connected with the eccentric and is operable to adjust the ec centric transversely of the shaft 3 to vary the throw of the rod 9. The rod 9 is pivotally connected with the clutch member 8 and a dog or other suitable means is adapted to connect the member 8 with the member 7 when the former moves in one direction but is released when moved in the reverse direction. By this construction rotation of the shaft 3 reciprocates the clutch member 8 and imparts a step by step or intermittent turning movement to the worm 6.

A substantially U shaped chute or guideway 14 is supported in the frame members 1 and 2 and overlies the worm 6. The chute 14 serves to support the material being sliced and the rear frame member 1 has an opening communicating with the chute 14 through which the material is fed to the knife 15 secured to the rear end of the shaft 3 and adapted to cooperate with the rear side of the member 1 to slice the material fed through the frame member 1.

Slidably mounted on the worm shaft 6 is a block or collar 16 having an upwardly extending portion 17 having two laterally extending branches 18 and 1,9 which are bent upwardly at substantially right angles and extend upwardly through longitudinal slots 20 and 21 in the bottom of the chute 14. A pusher 22 is suitably secured to the upper ends of the arms 18 and 19. Means are provided for releasably connecting the collar 16 with the worm 6. Said means comprises a bolt or pin 23 slidably mounted in the collar and having its inner end formed to engage the worm groove in the shaft 6. A spring 24 is coiled about the bolt 23 and tends to press the same into engagement with the worm. A finger piece 25 is ivoted to the collar, adjacent the handle 26 formed integral therewith, and has an arm 27 to which the outer end of the bolt 23 is pivotally connected. By pressing the finger piece 25 when graspinr the handle 26 the pin 24 is withdrawn from the Worm and the collar 16 together with the pusher 22 carried thereby is free to be moved longitudinally of the machine. In operation when the pusher has been moved to the rear end of the machine intermittently to feed the material to the knife 15, by grasping the handle 26 and withdrawing the pin 23 by means of the finger piece 25, the pusher can be returned and a new loaf or other material to be sliced placed in the chute 14. .By providing two slots 20 and 21 ad'acent the lateral edges of the chute 14 an two arms 18 and 19 to which the pusher is secured, the pusher may be moved more freely longitudinally of the machine with less binding action, than when a single slot immediately over the worm is employed.

It will be noted that the worm G is located near the middle of the machine and immediately beneath the chute 14. \Vith the pusher 22 carried by a single arm extending through a single slot in the chute, the slot must be near a point immediately over the worm with the result that crumbs falling through the slot catch in the worm groove and interfere with the free movement of the pusher and also tend to clog the worm groove and prevent the bolt 23 from sliding freely therein. I have overcome this diiliculty by providing two slots 20 and 21 laterally of: the worm 6 and having the bottom of the chute to protect the worm from crumbs.

Having described my invention, what I claim and desire to secure by Letters Patout is:

1. In a slicing machine, the combination of a frame, a cutter, a chute for the material to be sliced, a worm rcvolubly mounted in the frame beneath the chute, a pusher in the chute for feeding the material to the cutter, a pair of arms to which the pusher is secured adjacent its lateral edges, and means for operatively connecting said arms with the worm.

2. In a slicing machine, the combination of a frame, a cutter, a chute having longitudinal slots ad acent the lateral edges of its bottom wall in which the material to be .llll'ctl is supported, a collar having a pair of arms extending upwardly through the slots in the chute, a revoluble worm beneath the chute and between the slots in its bottom on which said collar is mounted, and a pusher in the chute carried by said arms.

3. In a. slicing machine, the combination of a frame, a cutter, a support in said frame for the material to be sliced having slots adjacent its lateral edges, a worm rcvolubly supported in said frame beneath the chute, means for rotating said worm, a collar supported on said worm and operatively con-- nected therewith, a pair of arms on said collar extending upwardly through the slots in the support, and a pusher carried by said arms and adapted to cooperate with the material on the support.

4;. In a slicing machine, the combination of a frame, a cutter, a support in said frame for the material to be sliced having slots adjacent its lateral edges, a worm revolubly supported in said frame beneath the chute, means for rotating said worm, a collar movably supported on said Worm, means for releasably connecting said collar to the worm to be operated thereby, a pair of arms on said collar extending upwardly through the slots in the support, and a pusher secured to said arms.

5. In a slicing machine, the combination of a frame, a cutter, a support for the material to be sliced having slots adjacent its lateral edges, a worm revolubly supported in said frame beneath the chute, means for rotating said worm, a collar supported on said worm, means on said collar adapted to engage the worm groove to operatively connext the collar with the worm, a pair of arms on the collar extending upwardly through the slots in the support, and a pusher securedto said arms.

6. In a slicing machine, the combination of a frame, a cutter, a support for the material to be sliced having slots adjacent its lateral edges, a worm revolubly supported in said frame beneath the chute, means for rotating said worm, a collar on said worm adapted to be operatively connected therewith, a pair of arms on said collar extending laterally outwardly and upwardly through the slots in the support, and a pusher secured to said arms.
