WILSON MARTIN KNOWLES, OF BROOKLYN, NEW YORK.

SLICING-MACHINE.

Specification of Letters Patent.

Patented Nov. '7, 1911.

Application filed August 5, 1910. Serial No. 575,718.

T 0 all whom it may concern:

Be it known that I, WILSON M. KNOWLES, a subject of the King of Great Britain, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Slicing-Machines, of which the'following is a specification.

This invention relates to improvements in slicing machines and more particularly to a machine for slicing tobacco.

One object is the provision of a device capable of having difierent attachments secured thereto so that relatively thin or thick slices may be cut from a slab of tobacco.

Another object is the provision of a means for automatically feeding the object to be sliced to the cutting blades.

With these and other objects in view, which will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size, and minor details of the device may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, forming part of the specification ;-Figure 1 is a plan view of the device. Fig. 2 is a side elevation thereof. Fig. 3 is a longitudinal section taken on the line 3-3 of Fig. 1. Fig. 4 is an end view.

Similar numerals of reference are employed to designate corresponding parts throughout.

In the form illustrated in Figs. 1 to 7 inclusive the device includes an oblong base plate designated by the numeral 5. Rising from the upper face and at one end of the base plate 5 is an upright 6. The outer face of the upright 6 is co-lncident with the end surface of the base plate 5 and formed on the lower end portion of the upright 6 is an oblong horizontally extending opening 7, of a size to permit the object operated upon to be passed therethrough. Formed integral or otherwise secured to the inner face of the upright 6 are a pair of spaced guides 8 and 9, the said guides extending longitudinally of the base plate 5 and terminating at a point adjacent to that end of the base plate remote from the upright 6. The upper faces of these guides are in a plane with the lower side of the opening 7, for a purpose to be presently described. Rising from that end portion of the base plate remote from the upright 6 is an upright 10, having its medial portion in alinement with the medial portion of the upright 6, as clearly shown in Fig. 1. The main shaft is designated by the numeral 11 and has its opposite end portions journaled in openings adjacent to the upper ends of the uprights 6 and 10, one end portion of the shaft 11 extending beyond the outer face of the upright 6 and has keyed or otherwise secured thereto a cutting blade 12, said cutting blade 12 having its cutting edge portion flexed toward the upright 6, so that when the said blade is rotated the cutting edge will coiiperate with the outer edges of the opening 7 to form a shear, whereby an object extending through the opening 7, will be cut by the blade 12 when the latter passes ove the opening 7. The free end of the on ting blade is provided with a lateral handle 13, providing a grip for the handle of the operator when rotating the blade 12 and shaft 11.

The follower is shown to include what will subsequently be termed a head portion 14. This member is preferably formed of an oblong piece of metal corresponding in width to the width of the object to be operated upon. Depending from the medial portion of the lower end of the head 14 is a boss 15, which bears on the opposed inner faces of the guide bars 8 and 9. vThe upper end of the block is medially provided with a depending recess 16, the lower end of which is rounded and which forms a bearing for the shaft 11, the sides of said recess bearing on the shaft and forming supplemental guides to prevent displacement of the head. A feed screw is designated by the numeral 17 and corresponds in length to the length of the shaft 11, or approximately so, and has one end fixedly secured to the central portion of the head 16, said screw being slidingly fitted in an opening formed in the upright 10 below the bearing of the shaft 11.

Keyed or otherwise secured to the shaft 11 and at a point adjacent to the upright 10 is a pinion 18, and threaded onto the feed screw 17 is a pinion 19. The pinion 19 has its opposite ends provided with circular flanges 20 and 21, the peripheries of which are beyond the ends of the teeth 22 of the pinion. The teeth 22 of the pinion 19 mesh with the pinion 18, while the flanges 20 and 21 bear on portions of the opposite faces of the pinion 18, so that when the handle 13 is turned in one direction the pinion 19 will be rotated, whereby the head 16 of the follower will be moved toward the upright 6, while the flanges 20 and 21, by virtue of their engagement with the pinionv 18 will prevent disengagement between the pinions 18 and 19.

From the foregoing, it is evident that I have provided a device which is comparatively simple in structure and inexpensive in manufacture, embodying few parts and these so arranged that the danger of derangement will be reduced to a minimum.

I claim 1. In a slicer, a base, end supports thereon, a shaft journaled in the end supports, guides extending on the base between the end supports a head slidable on the shaft and between the guides, a gear on one end of the shaft, a screw extending through the one of the end supports and connected to the head below the shaft, a gear on the shaft engaging the first gear having means to prevent disengagement therewith, the opposite end support having a delivery opening and being arranged flush with the adjacent base end, and a curved knife mounted on the shaft to work against said end support and base end.

2. In a tobacco cutter, a base, end sup ports located on the base, one of said end supports having a delivery slot therein and being flush. with one end of the base, a shaft journaled on the upper ends of the end sup- 40 ports, an arcuate handle having a cutting edge and mounted on the shaft whereby said cutting edge will engage the edges of the delivery opening in one of the end supports,

a gear on one end of the shaft, a screw movable through the other end support and provided with a member slidable on the base and on the shaft, guideways on the base for said member, and a gear mounted on the screw and in mesh with the first gear and provided with edge flanges.

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