This invention relates to machines forslicing meat and other material having areciprocating table for presenting the'material to the slicing knife.

The object of the lnvention is to provide means for readily disconnecting the driving Fig. 2 is a transverse section substantially on the line 1-1 of Fig. 1;

Fig. 3.is an elevation ofthe clamping device for locking the drive to the reciprocating table; H

Fig. 4 is a side elevation of the device shown in Fig. 3; and

Fig. 5 is atop plan view of the device shown in Fig. 3 with a bufier member carried thereon.

In the operation of slicing machines having rotary slicing knives and reciprocating tables it is sometimes desirable to be able to operate the drivingmechanism without reciprocating the table. For instance, during the grinding of the slicing knifethere may be dustfrom the grinding wheels which would fall upon the parts of the table or upon the meat carried by .the table if the table were permitted to continue its reciprocating movement past the slicing knife. If the table can be conveniently disconnected from its driving mechanism and permitted to remain at the forward end of itspath of movement. the table and the material carried thereby will not be subjected to the dust from the grinding wheels. This is referred to as an example of one occasion when it is desirable to disconnect the reciprocating'table from its driving mechanism. Many other occa sions mav arise when it will be advantageous to disconnect these parts. 7

Referring morespecificallv to the drawings. the numerals 1 and 2 designate the guide bars or ways on whichthe recipro' 9 to the knife spindle, not shown. The upcating table 3 is mounted to'slide. Themachine is provided with the usual rotary slicing knife 4, base or su'pportingframe 5 and hand wheel 6.". The base 5 carries'the usual upright studshaft having a beveled gear 7 mounted thereon drivenby a beveled pinion 13 securedto the end of the main drive shaft 12. The knife 4 is connected to the-gear 7 by a shaft 9, pinion. 8, and the usual connection extending upwardly from the shaft right shaft connected to the gear 7 carries a crank arm 10 tothe end of which the connecting rod 11 is journaled in the usual manner. The opposite end of the crank arm 11 instead of being pivoted to the forward cor her of the slidingtable 3 in the usual way,"

is pivotally connected to a swinging arm 14' having the opposite end pivotallv mounted FPATENTTOFFICE...

on the lower side of the table 3. The ends of the connecting rod 11 and arm 14 are pivoted together by means ofa hollow pivot pin 29. as shown in Fig.4. This pin has perfoe rated plugs threaded'into the opposite ends thereo throughwhich pins 15 and 16 pro ject. The pins 15 and 16 have po nted outer ends and are pressed outwardlv by means of a spring interposed between the inner ends of the pins. The lower faceof the-reciprocating table 3 at the forward corner thereof is provided with atapered recess for receivin the pointed end. of the pin 15., as shown n Fig. 2, and a bearing plate 17 isprovided having a tapered recess in its top face disposed in alinement with the recess, in the lower face of the table,3. I

. The be ring plate 17 is slidablv mounted between the arms of an H-sh aned supporting b acket 27 secured to the table 3. as shown in Figs. 1. 2 and 4. Guide p ns 20 and 21 are fixed. to the upperfaee of the'bearing plate 17, and are guided in openings in the crossbar 22 of the bracket 27. The table 3 is provided with openings for receiving the ends of the pins 20 and 2 1. Springs 23 and 24 surround the pins 20 and 21 and tend to force the hearing plate downwardly. A cam 19 is its operative position-the end of the connecting link 11 extends between the corner of the pins 15. and 16 extend into their respective table 3 and the bearing p1ate'17 so that the recesses so that the end of the connecting bar 11 is pivoted to the corner of the table. The arm 14: swings about its pivotal support, as shown in broken lines in Fig. 1, to permit'the connecting link to take" this position. The bearing "plate 17 is pressed upwardly by the cam 19 and handle 18 to hold the pins 15 and 16 in their sockets. lVhen it is desired to release the table 3 from its driving connection, it is only necessary to swing the arm 18, as indicated by the arrow in Fig. 4, until the restricted portion of the .cam engages the bearing plate .17. The springs 23 and 24 will force the bearing plate downwardly, releasing the pins 15 and 16 from their sockets so that the table 3 will remain stationary. and operation of the driving mechanism will only serve to swing the arm 14L about its pivotalsupport on the table 3. When it is desired to re-engage the table with its driving mechanism, it is only necessary to shove the table.

rearwardly until the pins 15 and 16 enter between .the bearing plate 17 and the portion of the table 3 provided with the recess for the pin 15. i The bearing plate 17 may be beveled on its forward edge, as shown at 28, to

assistin. lifting the pivotally connected heads of the bars 11 and 1a into position between the bearing block and table. Abuil'er 25 may be connected to the bracket 27 for engaging the heads of the arms 11 and 14 when the table is. moved forwardly to bring the parts into position to be clamped together. The table may be connected up with the connecting rod 11 at any position in the path of travel of the table The connection and disconnection is readily made since it is only necessary to swing the arm, 18 to clamp or unclamptlie head of the connecting rod 11 tothe tab e 3. Nhcnthe parts are disconnected the rod 11 is supported by the arm 14 and is guided in a fixed pathof movement during operation of the driving parts so that no parts are left loose to, be injured orv damage the machine.
