FEED MECHANISM FOR SLICING MACHINES.
Application led October 8, 1927, Serial No.
This linvention relates to mechanism for producing a step by step movement of the Work support for feeding the material toward the slicing machine knife and has for its object the provision of a feeding mechanism having, in addition to the usualL adjustment for thin and medium slices, a ooarser adjustment than has heretofore been possible for thicker slices. Other objects and advantages will appear from the following description.
Theinvent-ion is exemplified in the combination and arrangement of parts shown in the accompanying drawing,'and described in the following specification, and it is more particularly pointed out in the Y appended claims. 1
In the drawing z- Fig. l is an elevation of a slicing machine having one embodiment of the present invention applied thereto; Y
Fig. 2 is an elevation of the feed mechanism on a larger scale thanv that shown in Fig. 1;
Fig. 3 is a somewhat diagrammatic approximately horizontal section View of the feed mechanism.
In the drawing, the numeral 10 designates the base of a slicing machine having a rotary circular slicing knife 11 and a feed table 12. The feed table 12 is reciprocated in the usual way by a crank 13 and connecting rod 14 operated .by a handr wheel 15. A feed screw 16 is journaled in a bearing 17 on the table 12 and is provided with a projecting spindle 18 having an arm 19 pivoted thereon. The arm 19V is held against a stop pin 20 by a 'spring 21 and is arranged to engage an adjustable fixed sto 22 by means of which the arm 19 is swung cijownwardly and rearwardly against the tension of the spring 21 when the table 12 moves to its forward position. A gear segment 23 is formed integral with the arm 19 and meshes with a pinion 24 carried by a stud sha-ft 25 journaled in a link 26 pivotally mounted on the spindle 18. The opposite end of the stud shaft 25 from the pinion 24 carries a gear 27 which meshes with a pinion 28 ournaled on the spindle 18. An arm 29 is formed integral with the pinion 28 and carries a pawl 30 pivotally mounted at 31 thereon. The pawl 80 engages a ratchet wheel 32 fixed tothe spindle 18. The
224,828, and in Germany Decembei` 23, 1926.
Then it is desired to cut thick slices, the pin 84 will be withdrawn from thc opening 35 and inserted in an opening 36 in the stop pin 20. This will hold the link 26 in fixed position so that when the cam arm 19 is oscillated upon its spindle 18, the pinion 24- will be rotated by the gear segment 23 causing the gear 27 to drive the pinion 28 which carries the pawl arm 29. It will be seen from F ig. 8 that the gear ratio is such that the rotation is increased by the interposed gears 24 and 27 so that a` much greater movement will be imparted to the pawl arm 29 and consequentlq/l to the feed screw 16 than would be the case if the arms 19 and 29 were' moved in unison. In this way, a much coarscr adjustment is provided for cutting thick slices.
It is apparent that the coarser slices may be varied in thickness by adjusting the stop 22 in the same way that the thickness of the ner sliccsis adjusted.
