SLICING-MACHINE.

To all whom it may concern.'

Be it known that l, Jol-1N I. MCCORMICK, citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and usefullmprovements in Slicing- Machines, of which the following is a specification.

This invention comprehends certain new and 'useful improvements in apparatus for use in slicing bread or meats such as ham or bacon, and the invention has for its ob- ]ect, a simple, durable and e'Ilicient construction of apparatus of this character which will clamp and release the article being cut at each slicing operation, and which will also slide the article forwardly after each slicing `operation and immediately subsequent to the movement of the clamping means to the released position. And a further object of the invention, is an apparatus of this type embodying an improved construction and arrangement of parts whereby the stroke of the clamp may be easily regulated according to the thickness of the meat or like being cut and whereby also, the stroke of the feeding device may be regulated so asto secure thick or thin slices.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is a perspective view of an apparatus constructed in accordance with my invention; Fig. 2 is a transverse sectional view; Fig. 3 is a side elevation of the front portion of the apparatus; and, Fig. 4 is a detail horizontal section of one side of the apparatus.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accom anying drawings by the same reference c aracters.

Referring to the drawings, the numeral 1 designates the base of my improved slicing machine, said base comprising an elevated relatively stationary bed 2 formed with a sloping front end 3 and with a recess 4 at the upper end of the sloping portion 3, said recess defining a forwardly facing cutting edge Specification of Letters Patent.

5. Standards or brackets G are secured to the sides of the base 1 and project upwardly therefrom said standards being formed in their opposing faces with channels 7 in which the recessed side edges or guide rails 8 of a plate 9 are mounted for movement. This plate constitutes a portion of the clamp which also embodies a horizontally disposed plate 10 which is formed at its front edge with a series of teeth 11 designed to engage the `meat or other article to be cut immediately back of the cutting edge 5 of the base.

12 designates springs that are secured to the clamp and to the standards so as to normally hold the clamp at the upper limit of its movement and to return it to its upper position after it has been depressed for a clamping action.

The plate 0 of the clamp carries a stroke regulating screw 18 which is formed with a forked head 141 designed for engagement by a handle 157 the said handle serving to force the clamp downwardly into engagement with the meat or the like. lf the meat, for instance, be thick, the screw 13 is lowered in its socket so as to lengthen the stroke of the clamp. The actuating handle 15 of the clamp is mounted upon a transversely extending shaft 16 that is journalcd to turn about its longitudinal axis in the upper ends of the standards 6. This shaft 16 is provided at one end with a crank arm 17 adjustably held thereon by means of a set screw 18 as shown. The crank arm I7 eX- tends downwardly and carries at its free lower end a roller 19 designed to engage a lever 20. This lever 20 is mounted in and extends upwardly from a stub shaft 21 journalcd on lone of the standards G, and is connected to a pull spring 22 exerting a tension on the lever 2O to swing it in a forward direction. The said lever carries a push pawl 23 which -is designed to engage a ratchet wheel 24 mounted rigidly on the stub shaft 21. Within the base, said shaft 21 carries a pinion 24 which meshes with a gear wheel 25 secured to a transversely extending feed shaft 26 journaled in standards near the lower ends thereof. A series of feed disks 27 is mounted upon the shaft 26, said disks being provided with a continuous set of s urs 28 designed to project upwardly throng 1 slots 29 formed in the bed 2 of the base so as to continuously engage the article being sliced.

30 designates a stroke regulating bar that is secured to one of the standards 6, and

vie

which is formed with a series of holes any one of which is designed to receive a pin 31 so as to limit to diiferent degrees the forwardly swinging movement of' the lever 20. Rods 32 preferably of glass are secured to the front edges of the standards 6 so as to rovide a bearing surface for thel knife which will not dull it, said rods, in the resent instance, having their lower ends tted in sockets 83 formed in the standards and b eing secured at their upper ends to the standards by means of metallic straps 34.

For the purpose of describing the practical operation of myv improved ap aratus, it may be assumed that bacon is to lle sliced. The bacon is placed on the base 1 With the rind down so that the spurs 28 of the feed disks or wheels 27 enetrate the rind and secure a grip upon t e bacon. As. the operator resses the handle 15 downwardly with one land, the clamp is pressed into engagement with the Abacon and the knife is t en so pressed against the rods or tubes 32 as to cut through to the rind. After each slice is cut, the handle l5 is released whereupon the springs 12 raise the clamp and release it from the bacon. lt is to be particularly noted that in thismovement of the clamp to the released position, the bacon is released before the crank arm 17 comes into engagement with the lever 20 to swing the same in a direction to turn the feed disks 27 and thereby feed the bacon forwardly for the next slice. Obviously the changed from one hole'of t e stroke regulatingbar 30 to another so as Vto vary the swing of the lever20 and thereby regulate the forwardly feeding movement of the bacon and the thickness of the slices that are formed.

lt is to be noted that with the construction and arrangement of the parts illustrated in the accompanying drawings and described labove, it is not necessary to remove the rind from the bacon reparatory to slicing the same which would involve a loss to the merchant, and the apparatus does not require that the rind be cut through at ,every operation of the knife. lt will also be understood that my apparatus operates to cut the whole piece in uniform slices regardless of length without the necessity of an readjustment, the rind bein left on, until it is desired that it be remove Having thus described the invention, what is claimed as new is: l. An apparatus for use in slicing, comprisinga base, standards secured thereto and projecting above the same, a clamp mounted tojslide up and down in said standards, a stroke regulating screw mounted in said clamp, a handle arranged to en age said screw to move the clamp downward y, means for moving the clamp upwardly and a support for said handle.
