To all whom it may concern:

Be it known that I.,- CoRNELrs F. M.- VAN BERKEL, a subject of the Queen of the NethofLaporte, and State of Indiana, have invented certain new and useful Improvements in Clamps for Slicing-Machines, of which the following is a spebification.

This invention relates to a device for hold} ing material to be sliced by the blade of a; slicing machine, and has for its object the provision of a clamp of the character mentioned which shall be of improved construction and more efiieient in its operation than slmilar devices previouslyknown.

The invention is exemplified in the combi-' I nation and arrangement of parts shown in the accompanying drawings and described in the following specification and i ismore particularly pointed out in claims. a

the appended In the drawings: Figure 1 is a top'plan view of a clamp showing one embodiment of the present invention; Fig. 1 is a frag. mentary section showing details of the clutch collar; Fig. 2 is a front elevation of.

the clamp shownin Fig. 1, Fig. '3 is a fragmentary top plan view of a modified form of theinvention, Fig. 4; is a front-elevation with parts broken away of the device shown in Fig. 3, Fig. 5 is a fragmentary elevational view showing the post grip and operating lever therefor, and Fig. 6 is a section on line %6 of Fig. 5.

Th s invention comprises a clamp of the same general character as that shown in Patent No. 1,175,025,'granted May 1st, 19 16 land includes features of improvement over the structure shown in that patent.

Referring first to Figs. '1 and 2 of the drawing the numeral '10 designates the plate on which the meat, or other substance to be sliced, is held while. it is being presented to the slicing knife. Atone corner of the plate 10, adjacent the front edge'thereof, is an upright post or standard 11 and on the diagonally opposite corner is a second similar standard 12. Surrounding the post 11 is a sliding grip collar 13 which fits the post somewhat loosely. The grip collar 13 is p'r rvided with av laterally extending arm 1% on which the clamping bar 15- is mounted byflinean's of a pivot pin 16. The clutch sleeve 13 is" provided with an upsuch movement since it is held with i tical sides parallel with the sides of the post I Specification of Letters'Patent.

vents the sleeve from gripping the post 11.

. when downward pressure is exerted on the pivot pin 16. Ifv pressure is exerted up? wardly on the pin 16 the long bearing surface 15 is thrown inwardlyaway from the post 11 and, the sleeve will grip the post and resist upwardmovenient. The uppen part of the be'aring portion 17 is providedwith a forwardly extending finger 18 which overlies the upper edge of the clamp 13 so that when the clamp is tilted upwardly, as shown in Fig. 2, the upper edge of the clamp will j come into contact with theloWer surface of the finger 18 and .thus tilt the ip sleeve 13 the collar to slide upwardly. It will be ap parpnt that if theclamp 15 is held" at the an gle shown in Fig. 2and moved bodily in' an to release its hold upon the po .t and permit I upward directiom the sleeve 13.Will ermit;

Iver

11 under these conditions.

The endof the clamp 15, opposite the post -11, 'i's supportediby the arm 19 carried by a sleeve 20 arranged to slide upon the post 12. The movement of the sleeve 20 upon the post 12is controlled by a handle 21 and a clutch grip 22. The clamp 15 is secured to the for-- I passes, has a limited swiveling movement about a horizontal axis relative to the arm' 19, so that the clamp. 15 is free to swing about the horizontal .aXis extending'inthe' direction of the arm 19.

This. swingingward end of the arm 19 by a bolt '23 which movement, however, is so limited, that the end ofthe clamp. adjacent the post 11 will .l

not swing downwardly below the position shown in Fig. 2, in which position the finger 18 will bear upon the upper surface of the" clamp. It. will be apparent, therefore, then when upward pressure is exerted upon thm handle 21 and the arm 19,-the clamp 15 will, assume the position shown in Fig. 2. in

which positionthe clutchsleeve 13 will be free. to slide upon the post 11 and therenicy-upward pressure-on the handle 21. In a tire device may be raised upwardly simply similar way, the entire clamp may be moved downwardly by simple downward movement of the handle 21, because the sleeve 13 does not resist downward pressure upon the pivot pin 16, as previously explained.

In operation, when the clamp has been brought intoposition to contact with a piece of meat 25, or similar material, further downward movement will tilt the clamp tending to force the pivot pin 16 upwardly. This will be resisted by the clamp sleeve 13, however, and the result of such downward pressure upon the handle 21 will be to bring the clamping bar firmly into engagement far described, is all shown in the prior patent referred to.

If a pieceof meat to be clamped is of the shapp and firm nature of a piece of bacon, for instance, it will be apparent from Fig. 2 that the clamp will first strike the corner of the meat adjacent the post 11] Further downward pressure upon the handle 21 will 5 tend to bring the end of the clamp 15 at the right in that figure into contact with the right hand side of the piece of meat, but it is readily apparent that the greatest pressure will be exerted on the edge of the meat adjacent the post 11 and if the meat is very firm in character, it may happen that the operator will not be able to bring the opposite end of the clamp into contact with the meat at all. To remedy this difliculty, applicant has provided a bar or plate 26 which ispivotally supported on the pin 16 between the clutch sleeve 13 and the end of the clamp 15. Theplate 26 is provided with an upwardly extending shoulder 27 the upper 40 surface of which normally extends to a position level with the upper surface of the clamping .bar 15, as shown in Fig. 2. In this figure, a portion of the clamping bar 15 is broken away to permit the plate 26 to be seen. The portion of the clamp 15 that has been removed is shown in broken lines. The plate 26 is provided with an extension rod 28 which is provided with an upwardly bent portion 29 which rests upon the upper surface of the end of the arm 19 and forms a finger piece by which the plate 26 may be tilted upwardly about the pivot pm 16.

lVhen the clamp has been brought into the position shown in Fig. 2, the operator may raise the end of the rod 29 and thus force the finger 18 upwardly and release the clamping action of the collar 13 on the post 11. If downward pressure is now exerted upon the handle 21, the pivot pin 16 may be tilted upwardly about the polnt of contact of the bar 15 with the meat until the clamping bar has been brought into a position to contact with the entire upper surface of the meat. The bar as 19 may then be released wh ch W111 permit about the point of contact with the meat,-

with the piece of meat. The clamp, as thus the clutch sleeve 13 to again clamp the post 11 and further downward pressure upon the handle 21 will cause the bar to exert pressure on the meat along its entire upper surface. It will be apparent that the position of the clamp 13 upon the bar 11 may be adjusted to any desired position and caused to grip the post in this position for releasing the extension rod 29 when the proper position has been obtained.

In the form of invention shown in Figs. 3 to 6, inclusive, the manually operated plate 26 is replaced by a bell crank lever 30 pivotally mounted on one side of the bar 15, as shown at 31 in the drawings. One-end of the bell crank lever 30 is provided with a cylindrical lug 32 extending betweenprojections 33 and 31 carried by the clutch collar 13. The other arm of the bell crank lever 30 extends to a position adjacent the lower edge of the clamping bar 15 and carries a forwardly extending bar or rod 36 which supports a tripping plate 37 positioned beneath the clamping bar 15 and between the downwardly extending teeth thereof, as best shown in Fig. 6. A notch 38 (Fig. 5) is cut in the bar 15 to permit pivotal movement of the bell crank 30 about the support 31. hen the clamping bar 15 has been moved into the position shown in Figs. 4 and 5, the tripping plate 37 will contact with the upper surface of the meat 25 slightly in advance of the teeth of the bar 15. hen this occurs the bell crank lever 30 will be thrown upwardly, as shown in broken lines in Fig. 5, and the clutch sleeve 13 will be prevented from gripping the bar 11. This will leave the end of the bar 15 carried by the pin 16 free to tilt upwardly the amount necessary to bring the bar 15 into a horizontal position. This upward movement of the pin 16 will carry the sleeve 13 with it and hence tilt the bell crank lever 30 upwardly at the same time that the clamping bar 15 is swinging downwardly about the pivot 16. This will cause the rod 36 to swing upwardly in its groove 38 and bring the tripping plate 37 into position between the downwardly extending rows of teeth of the clamping bar 15. The parts are so proportioned that when the bar 15 has reached a horizontal position, the plate 37 will be located between the rows of teeth of the bar so that it will no longer interfere with the gripping action of the collar 13 which will thus be free to hold the pin 16 from upward movement so that the clamp ing bar may be made to exert pressure in a horizontal position across the entire upper surface of the meat to be clamped. It will be seen that in this forni of the invention, the clamping bar is automatically caused to aline itself with the upper surface of the material to be clamped, so that it is not necessary to manipulate the clamping loop 13 :by hand; as isdone in "the form previously described;
