SLICING MACHNE.

Application filed June 18,

Tol all whom t may concer/n.'

Be it known that I, Josnri-r C. PRINS, a citizen of the United States, residing in Hornell, in the county of Steuben 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 a slicing machine and more particularly to the means whereby the article to be sliced is fed for ward to new parts thereof to the cutter as the slices are successively cut from the body of the article.

It is the object of this invention to provide simple, eflicient and reliable means for feeding the article to the cutting line which .are so constructed as to permit of quickly and easily either advancing or retracting the article supporter and also wholly removing the latter from the machine when the same is to be cleaned. f

In the accompanying drawings:

Figure 1 is a top plan view of a part of a slicing machine equipped with my invention. `Figure 2 is a rear end elevation of the saine. Figure 3 is a fragmentary vertical transverse section, on an enlarged scale, taken on line 3 3, Fig. 1. Figure 4 is a fragmentary horizontal section taken on line 4-45 Fig. 3.

Similar characters of reference refer to like parts throughout the several views.

The carriage or table of the slicing machine forming part of the means for presenting the article to be sliced to the cutterV or blade which cuts the article into slices may be variously constructed but in the form shown in the drawings the same comprises a marginal frame 10 and a panel 11 secured to the central part of the frame by bolts 13 or similar means. This table may be reciprocated so that its front end moves back and forth relatively to a cutter, or the table may be fixed and the cutter moved back and forth past the front end of the table beyond which the article to be sliced projects.

Above the table is arranged the supporting plate 14 upon which the article to be sliced is fastened by holding or clamping means of any suitable and approved character which however form no part of the present invention.

y The means containing my invention for guiding the plate on the table and holding' 1920. Serial No. 389,798.

the same normally against lateral displace ment but permitting the plate to be readily removed for cleaning are constructed as follows 15, 16 represent two longitudinal guideways arranged lengthwise on the upper side of the table adjacent to the opposite longitudinal edges, the guideway 15 being preferably fiat and horizontal and the guideway 16 being constructed in the form of a longitudinal groove which is preferably rounding in cross section, as shown in Figs. 2 and 3. On the underside of the supporting' plate adjacent to one of its longitudinal edges the same is provided with feet or bearing points 17 of fiber or similar material which slidingly engage with the flat horizontal guideway 15 of the table and on its underside adjacent to its opposite longitudinal edgethis plate is provided with a longitudinal guide rib 18 which is preferably rounding in cross section and engages with the groove of the table. By this means the supporting plate will he guided in its longitudinal movement on the table but held against lateral displacement so that the article supported on the plate will always be properly presented to the cutter and insure cutting uniformly thin slices. The radius upon which the guide groove is formed is preferably less than the radius upon which the guide rib is formed so that when the rib en- 'gages the groove the lowest part of the i'ibiwill notwtouch the bottom of the groove and thus permit the rib to constantly center itself in the groove and take up wear between the co-operating surfaces of the guide rib and groove without causing any looseness between these parts and avoiding noise in operating the machine or uneven cutting of slices from the article 0n the supporting plate.

A downward pressure is constantly exerted against the upper side of the supporting plate adjacent to that edge thereof which has the guide rib so as to keep the latter in proper engagement with the guide groove during the normal operation of the machine. The preferred means for this purpose shown in the drawings comprise a presser plate or bar 19 mounted lengthwise on the table adjacent to the outer side of the guide groeve therein and engaging with the upper side of the adjacent longitudinal edge portion of the supporting plate. 'flic outer longitudinal edge of the presser plate preferably rests upon a raised bead on the table upon which the presser plate can tarn vertically as a fulcrum while the inner odge of this presser plate bears against a longitudinal flange 2l j )rojectinglaterally from the supporting plate beyond the guion rib thereof. This presser plate is constantly pressed downwardly b v tension means which in the present case comprise a plurality of npright bolts 22 arranged in a lon! 't-udinal row and passing through i openings in the table and presser plate adjacent to the guide rib and groove, each of these bolts engaging the head at its upper end with the top of the presser plate and being` drawn downwardly by a spring` 23 which surrounds the bolt and bears at its ripper end against the bottom of a recess or pocket 24 in the underside of the table while its lower end bears against the nut of this bolt, as best shown in Fig.

As the article supjiorting 7)late slides forwardly or bacliwardly on the table the guide rib and groove between the same are held firmly in engagement with each other by this tension device and any wear between the same is automatically'taken up thereby. When however, it becomes necessary to re move the supporting plate from the table for cleaning, inspection or repairing, this can be easily done by first lifting that edge of the supporting plate opposite its guide rib, as shown by dotted lines in Fig, and

then moving the supportingf plate tothe unribbed edge thereof when these members may be quickly and easily separated or dismembered for'any desired purpose, Assembling of these members be easily effected by manipulating the same in reverse order of that just described. A

For convenience in manipljllating the supporting plate the same is provided on its upper side adjacent to its opposite longitudinal edges with handles Q5, 26.

The improved means for moving the article supporting plate lengthwise of the table in accordance with my invention are constructed as follows:

27 represents a screw threaded feed shaft arranged lengthwise and horizontally along that side of the table and supporting plate at which the rib and guideway` between the same is located. This shaft is journaled in bearings 28, 29 on the adjacent partof the table so as to be capable of turning but held against 'lengthwise movement. This screw shaft maybe Ytnrned in any suitable manner but '1n -prfactice'means arev usually provided for Yturning the same forwardly either man iuatlly or automatically and also turning the Asame -backwardly manually, but the mecha.-

nism for operating this shaft forms no part ofthe present invention. l

it/lounted on the screw threaded shaft is a shifting member 'which is operatively connected therewith. This member in the preferreifl construction has the form of a shifting member 30 having the form ofy a sleeve which surrounds the screw shaft and is pro vided with an upwardly projectingl boss 3l which contains a cylindrical radial guidewaiv opening at its inn-er end to the shaft while its outer end is closed. `Within this cylindrical guide way, a cylindrical follower is movable toward and from the screw and also turning in this guideway. represents a shifting rod arranged in the cylindrical guideway and having its inner end connected with the follower while its outer part extends through the outer end of the boss and is provided externally of the latter with a nger piece or handle for manipulating the same. The follower is yieldingly held in engagement with the thread of the screw shaft by a spring 36 arranged in the cylindrical guide and engaging at one end with the bottoni of said guide while its other end engages with'said follower. Vifhen the latter engages the thread of the screw shaft than a turning movement of the latter causes the shifting member or sleeve to move lengthwise of the shaft but when the follower is withdrawn from the screw shaft then the rotation of the shaft does not affect the shifting Vsleeve and the latter may be moved lengthwise of the shaft to the desired position. 'For the purpose of retaining the follower in its operative and inoperative position at will the outer end ofthe guide boss is provided with an elevated flat face 37 which is perpendicular to the axis of the shifting rod and at another part of the outer end of this boss the same is provided with a recess 38.' On its inner or underside the finger piece is provided with a retaining pin or projection 39 which may be engageifl with recess 38 and permit the follower to intermesh with the thread of the screw shaft, as shown in Fig. 3, when it is desired to move the shiftingsleeve by the rotation o-f this shaft, When however this sleeve is to 'be retained temporarily in disconnected condition from "the v screw shaft then the shifting rod and follower are pulled outwardly by the finger piece until the follower is withdrawn from'jthe thread of the screw shaft after lwhich ,the finger piece is turned and its retaining pin '39 engages with the elevated face '37 of the boss whereby the shifting sleeve and shaft will be uncoupled,

'In order to permit of moving the article supporting 4plate forwardlybythe forward movement of the shifting sleeve the latter is provided with an 'inwardly projecting tappet 4-0 which is adapted to engage with abutment ll on the'supporting plate, this abutment being preferably formed ini/i/iaeeo tegrally with the adjacent handle 26 olf the supporting plate, as shown 'in Fig. l. The contact surface of the tappet is preferably formed by means of a hardened screw -lZ arranged in a. threaded opening in the tappet and engaging the abutment.

'For the purpose of guiding` the shitting sleeve in its longitudinal. movement and holding the same against turning relatively to the screw shai't this sleeve is provided with two guide arms 43, 44, projecting therefrom at an angle relatively to each other, and adapted to engage two longitudinal guide surfaces 45, 46 arranged at an angle relatively to each other on the table and associated parts, the guide surface 45 for the upper arm 43 being formed on the upper side of the presser plate 19 and the guide surface 46 for the lower arm 44 being formed on the outer side of the table, as shown in Fig. 3. To prevent noise and undue friction the guide arms 43, 44 are provided with contact plugs 47 of ber or the like lor engagement with the guide surfaces, which plugs are seated in recesses in the respective arms.

Bymeans of the construction the article supporting plate may be freely removed i'rom the table and reassembled therewith without disturbing the mechanism whereby JOSEPH C. PRIMS.
