FOOD-CHOPPER.

SIRECIFIGATION forming part of Letters Patent No. '71 1,837, dated. October 21, 1902.

I Application filed May 11,1901, Serial No. 59,821. (No model.)

T0 to whom it mayconccrn:

Be it known that'I, HENRY O. EVANS, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and'useful Improvement in Food-Choppers, of which the following is a specification.

My invention consists of an improved construction of a food-chopper wherein'I provide novel means for enabling the cutting device and itsadjuncts to be withdrawn from the casing in an assembled condition in an expeditious manner, whereby the parts can be frequently inspected and cleaned, according to requirements.

It also consists of a novel construction of devices for locking the parts in assembled position.

It also consists of 'a'novel construction of a pivotal jaw for holding the bracket which supports the casing or body of the chopper in position, whereby the device is rigidly held to the table or bed during the action of the chopper.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a vertical sectional view of a food-chooper embodying my invention, certain of the partsbeing shown in elevation. Fig. 2 represents an end elevation of the chopper. Fig. 3 represents a plan View of the locking device seen in Fig. 2.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the chopper, consisting of a casing or body 2, having the mouth or inlet 3, said casing being supported upon the bracket or post 4, which is secured'to a table, bed, or other support 5 by means of the stationary jaw or jaws 6 and the movable jaw 7, which has the thumbscrew 10, bearing upon a recess in the under portion of said movable jaw, the extremity of said thumb-screw being seated in saidrecess or channel.

11 designates a crank or other handle having the squared or polygonal seat 12 and the opening 13 in the upper portion thereof, in which seat and opening, respectively, are received the parts 14 and 15, of corresponding contour, which extend from the forcer 16, which preferably'consists of a Worm or spiral 17, which is adapted-to force the material to be chopped along thebottom 18 of the easing 2. The bearing 19 of the handle 11 is retained in position within the casing by means of the washer 20 and the retaining-ring or similar device 21;

22 designates a plate having the openings 23 therein, said plate being detachably mounted on the discharge end 24 of the easing 2, the upper portion of the plate 22 being provided with an inwardly-projecting lug 25, which has the recess 26 therein, which engages the upward projection or lug 27 of the casing, said. lug 27 having the dog or catch 28 pivotally mounted thereon by means of the pin 29. The'nose30 of said dog engages a recess 31 in the periphery of the plate 22, whereby the latter is prevented from rotation and is detachably coupled in a simple and efiective manner to the discharge end of the casing 2.

I desire to call especial attention to the feature of having the dog 28 projecting in longitudinal alinement with the forcer and having its under side 28 extended, so as to project beyond the plate 22 in the manner seen in Figs. 1 and 3, since the under side of said dog serves as a species of Wiper and prevents clogging of the food which is being chopped around the outlet-openings 23 of the plate 22, as will be apparent. The under side of the plate 22 is provided with a recessed lug 32, which is similar to the lug 25 seen in Fig. 3 and is adapted to engage the lug or projection33 on the under side of the body 2, said lug 32 being provided with a recess 34., so that the nose of the dog 28 is adapted to engage therein with the same facility as with the recess 31.

35 designates a thumb-screw which is adapted to be screwed into the forcer 16 in the manner indicated in Fig. 1, said forcer having the cylindrical journal 36 formed thereon, which has its bearing in the plate 22, and said forcer being continued to form the squared extension 37 ,which engages a squared or polygonalshaped opening in the cutter 38, whereby it will be seen that when the parts are assem bled, as in Fig. 1, the forcer 16 has its hearing in the stationaryplate 22, while the cutter 38, mounted on the squared extension 37 of said forcer, revolves in unison therewith.

I desire to call especial attention to the location of the cutter 38, exterior to the plate 22. By reason of said location all of the material is cut and none of the same is left inside of the chopper, as is the case when the cutter is located interiorly of the apertured plate.

40 designates a lug projecting from or cast on the side of the casing or body 2 and adapted to support the cutters 41, 42, and 43 when not in use.

It will be apparent that the rotation of the forcer 16 will force the material to be chopped through the openings 23 in the stationary plate 22 and that said material will be cut by the contiguous cutting edges of the cutter 38 during the revolution thereof.

When itis desired to clean the apparatus, (seen in Figs. 1 to 3, inclusive,) it is only necessary to lift the dog 28 and turn the plate 22, whereupon the forcer 16, the parts 14 and 15, as well as the stationary plate 22, and the retary cutter 38 can be readily withdrawn in assembled position or as in one piece from the body 2, while the bearing 19 of the handle remains within the casing, thus producing a two-part chopper, as it were, which is readily accessible at all times and not liable to get out of order. The cutter 38 can be readily removed after taking off the thumb-screw 35, and the plate 22 can also be readily disconnected from the forcer 16, as will be evident.

In assembling the parts it is immaterial whether the recess 31 or the recess 34 is up permost, as the nose of the dog 28 can engage either one with equal facility.

I desire to call especial attention to the fact that the contiguous faces of the cutter 38 and the apertured plate 22 are fiat, whereby the same can be easily sharpened when desired by simply rubbing said contiguous faces upon a fiat piece of emery-cloth or similar material, so that the sharpening of the device can be much more readily effected than it can where the contiguous faces, as of the plate 22 and cutter 38, are conical or arc-shaped.

Having thus describedmy invention, what I claim as new, and desire to secure by Letters Patent, is-
