'SLIGING-MACHINE.

Specification of Letters Patent.

Patented Sept. 21, 1920.

Application filed March 18, 1919. Serial No. 283,411.

To allwhom it may concern:

I Be it known that I, WALTER CHANDLER KNAPP, 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 following to be a full, clear, and exact description of the same, taken in connection with the accompanying drawings, forming a part of this specification.

My invention relates to slicing machines, more particularly to that kind of slicing machine employed for slicing bread and the like, in which the material being sliced is fed step by step to a revolving cutter or knife. The object of my invention is to provide a machine of this class with means for saving the crumbs which are usually scattered on the floor. A further object of my invention is to provide a chute at the lower side of the knife hood for directing the crumbs falling therefrom inwardly and downwardly to a' receptacle provided therefor beneath the machine.

To these and other ends my invention resides 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 showing the application of my improvement, the front end of the machine being broken away, and

Fig. 2 is a rear end elevation of the same.

Similar reference numerals refer to the same parts in all the figures of the draw- Iify slicing machine comprises a frame 1 in which is rotatably mounted a shaft 2 having a knife 3 secured thereto at its rear end. A collar 4 is secured to the shaft to engage the frame and constitutes a thrust bearing for the shaft. The rear end frame member has a rectangular opening 5 therein, through which the material to be sliced is fed to the knife which cooperates with the rear end of the frame to slice the material. A chute 6 is supported in the frame and serves to support the material, as it is fed to the knife. A pusher 7 is adapted to have a step by step movement in the chute to move the material to the knife. If desired the pusher may be provided with a plurality of points 8 adapted to positively engage the material to be sliced. A worm 9 is rotatively mounted in the frame beneath the chute, and is operatively connected with the pusher. Means, not shown herein, are provided for imparting a step by step rotary movement to the worm for moving the pusher forwardly step by step between successive strokes of the knife. If desired, a table or support 10 may be provided at the rear end of the chute 6 to catch and support the sliced material.

A hood or guard ll constructial of sheet metal. and of substantially inverted U shape is suitably secured to the rear end of the frame and incloses the knife. The hood comprises front and rear walls 12 and 13 connected at their outer peripheries by the wall 14, and open at the lower ends as at 15. The walls 12 and 13 are cut away centrally to provide a clearance for the material being sliced.

In practice it has been found that a large quantity of crumbs fall to the table from between the chute 6 and the support 10 and also from the hood or guard 11 especially from the right hand side as viewed in Fig. 2 of the drawings toward which the knife moves. These crumbs falling from the hood usually fall to the floor and are not only lost but cause an unsightly appearance. My invention consists in providing means for catching the crumbs falling from the hood and directing them into a receptacle adapted to receive them and also the crumbs fall ing from between the chute 6 and the support 10. To this end I provide a. chute or crumb catcher 16 substantially U shaped in cross section and adapted to cooperate with the front, rear, and side walls of the hood and projecting downwardly and inwardly to catch the crumbs falling from the hood and direct them to the receptacle 17 which may be provided to receive them. The chute 16 may be made integral v. iththe hood 11 or is preferably made separate therefrom and secured in position with its upper and side edges in contact with the walls of the chute by any suitable means, such as screws. While I show and describe only one chute or crumb catcher 16 applied to that side of the hood toward which the knife moves it is to be understood that I do not desire to be limited to the exact construction illustrated and described herein,

but that another chute 16 may be employed on the other side of the hood if desirable Without departing from the spirit or scope of my invention.

Having described my invention What 1 claim and desire to secure by Letters Patent 1. In a slicing machine, the combination of a frame. a knife revolubly mounted therein, a chute for guiding the materiel to the knife, a support for the sliced material, a hood for protecting the knife, an a crumb chute cooperating With the hood and adapted to direct crumbs to a receptacle adapted to receive them.

2. In a slicin machine, the combination of a. frame, a knife revolubly mounted therein, a hood for protecting the knife. and a crumb chute secured to the Walls of the hood renews and adapted to direct crumbs downwardly and inwardly to a point beneath the kngfc,

3. In a slicin mttchine, the combination of a, frame, a knife revolubly mounted therein, a hood for protecting the knife, and a crumb chute cooperating with the front, rear, and side walls of the hood and projecting inwardly to direct crumbs to a point beneath the knife.

4. In a slicing machine, the combination of a frame, a knife revolubly mounted there in, a hood inolosing the knife and open at its lower end, and a crumb chute projecting inwardly and downwardly from theopen end of the hood and adapted to direct crumbs into a receptacle adapted to receive them.
