CUTTER.

Specification of Letters Patent.

Patented July 30, 1912.

Application filed November 30, 1910. Serial No. 595,958.

To all 'LU/LOWL it may concern Be it known that I, ELLIOTT W. Jones, a citizen of the United States, residing at Opeli-ka, in the county of Lee and State of such as will enable others skilled in the art I to which it appertains to make and use the same.

in cutters, particularly of that type in which a pivoted knife is operated by one hand, while the article to be sliced is being fed to the knife by mechanism operated by the other hand of the operative. In my former Patent No. 927,247, of July 6, 1909, I have disclosed a machine of this type, and in the present invention, I have made a substantial change in the general arrangement and construction of the operating parts to more particularly adapt the machine for slicing meats such as sides of bacon and similar meats having bones therein, or otherwise.

A further object of the invention is to provide means for controlling the feed of the feeding means whereby slices may be cut of uniform thickness, which thickness may be varied in accordance with the desiresof the customer to be served.

While the invention is not restricted to the exact details shown and described, still for the purpose of disclosure, reference is had to the accompanying drawings illustrating a practical embodiment of the same, in which drawings like characters designate the same parts in the several views, and in which:

Figure 1 is a plan view; Fig. 2 is a view in end elevation; Fig. 3 is a view in end elevation looking from the opposite side of the machine from that shown in Fig. 2; Fig. a is an enlarged view of the operating apparatus shown in Fig. 2; and Fig. 5 is a local view in cross section on the line 5-5 in Fig. 1.

1 designates a table or base which may be mounted on legs if desired and on its base is pivotally mounted a swinging knife preferably of curved construction, associated with a sliding abutment adapted to feed the article being sliced to the knife. The knife may be located in any position relatively to the cutting edge on the base, but in the drawings I have shown the base 1 provided with a slot 2 adjacent which may be arranged metal plates 3 secured to the base 1 of wood or. other suitable material, and the knife 4:, shown in its elevated position in Fig. 1 is pivoted at one end to a suitable standard or bracket 5, and is preferably of a construction having a substantial curve at its pivoted end thence extending in the form of an elongated continuation of said curved end, terminating in a handle 6. The This invention relates to improvements sliding abutment 7 is disposed transversely over the top of the base and may be provided with impinging hooks 8 if the cutter is to be used as a meat cutter. The movable abutment is of course arranged parallel to the knife slot;

One of the particular features of novelty of the presentinvention is the construction and arrangement of parts whereby the abutment is fed toward-the knife and by the present invention this is accomplished by providing a shaft 9 extending transversely of the base and having on its ends pinions 10 and 11, which pinions mesh with rack bars 12, to which aresecured the ends of the movable abutment, and which rack bars are of channeled construction having their re cessed sides disposed outwardly, with the top horizontal web 13 lying substantially flush with the top of the base, and the lower horizontal web being provided on its underneath side with rack teeth 14: adapted to register with the pinions 10 and 11, to feed the. rack bar forwardly or rearwardly together with the sliding abutment 7. I also provide guiding means for mounting and maintaining the rack bars in position and in the present case this means is shown as consisting of a pair of elongated plates 15 held slightly spaced or offset from the sides of the base in order to allow the channeled rack bars to lie alongside of said base with their vertical webs disposed between said base and said elongated plates 15, the latter being adapted to seat within the channeled rack bars and hold same in their proper position. This elongated plate 15 is held spaced from the base at its forward end (Fig. 5) by means of vertical securing members comprising laterally projecting loops 16, terminating at their lower end in a vertical strip 17, secured to the sides of the base 1, and it will be observed from Fig. 5 that the elongated plate 15 is offset a little to the left of the securing strips 17 providing for a space bet-ween the elongated plates and the base 1, as before stated.

At the rear of the apparatus the elongated plates project beyond the rear of the base and are bent back upon themselves to form rearwardly disposed looped extensions 18 and at their extreme ends bent at right angles and secured to the base as at 19. The space 20 between the walls of the looped ex tensions corresponds with the space between the elongated plates and the sides of the base, so that the movable abutment can be shifted rearwardly beyond the base a considerable distance if desired or until the vertical webs 12 of the channeled rack bars abut against the ends of the looped extension, which will limit the rearward movement of the sliding abutment.

lVith the construction described, any suitable means may be employed for feeding the movable abutment forward, but it is generally desired, however, to feed the movable abutment forward with a step by step motion and in the drawings I have illustrated a lever and ratchet arrangement for accomplishing this movement. To this end I pro vide a gear wheel 21 near the end of the shaft 9 and on the shaft 9 I also loosely pivot a lever 22, carrying a reversible pawl 23 of a peculiar construction pivoted at one end as at 24 to the lever and at its other end adapted to coact with the teeth of the gear wheel 21.

It'will be understood that while this machine may be used for slicing various articles, the same is particularly designed for slicing sides of bacon and similar meat, and it will be clear that with the arrangement of the feed mechanism, the meat may be fed up to the knife and the knife swung in its plane to completely sever each slice. This may be done without bending over, and at the same time providing sufficient leverage on the knife to properly sever the slices of meat without requiring a great amount of exertion. In actual practice, the base of the cutter may be placed substantially on the ground or floor, where the operative may operate the machine in an upright position.

From the foregoing, it is believed that the operation is quite clear. If the abutment is to be fed forwardly the pawl is thrown to the position shown in full lines in the figures and if the abutment is to be fed rearwardly,

the pawl is reversed with the finger 26 thrown into engagement with the gear wheel as shown in dotted lines in Fig. 2.

Any suitable means may be employed for guiding the stroke of the lever, as well as means for limiting its stroke in the direction of its forward feed, to regulate the feed and the thickness of the cut, and in the drawings I have shown a'retainer comprismg the vertical arms 27 secured to the base 1, the upper ends of the arms being subtended by the retaining bar 28, on which is slidingly mounted a stop 29 disposed in the path of swing of the lever, and held in its ad justed positions by means of a set screw 30.

Having thus described a practical and preferred embodiment of my invention, the particular features of novelty will now be pointed out more succinctly in the following claims 1. In a cutter, the combination of a base, a knife secured thereto, a slidable abutment extending across said base parallel to said knife, racks secured to the ends of said abutment, a shaft journaled in said base parallel to said knife, pinions secured to said shaft in mesh with said racks, a ratchet wheel secured to said shaft, a lever journaled on said shaft, a reversible pawl pivoted on said lever, a stationary retainer for guiding said lever and limiting the rearward swing thereof, and an adjustable stop on said retainer for limiting the forward swing of said lever.

In a cutter, the combination of a base, a knife secured thereto, a slidable abutment extending across said base parallel to said knife, hooks extending from the upper surface of said slidable abutment, racks secured to the ends of said abutment, a shaft journaled in said base parallel to said knife, pinions secured to said shaft in mesh with said racks, a ratchet wheel secured to said shaft, a lever journaled on said shaft, a reversible pawl pivoted on said lever, a stationary retainer for guiding said lever and limiting the rearward swing thereof, and an adjustable stop on said retainer for limiting the forward swing of said lever.

In testimony whereof, I aiiix my signature, in presence of two witnesses.
