Description

Sep't. 23, 1930. w. RIENKs SLIGING MACHINE Filed May 10, 1928 Patented Sept. 23, 1930 UNITED STATES PATENT oFFicE WILLIAM RIENKS, OF ROTTERDAM, NETHERLANDS, ASSIGNOR TO U. S. SLICING MA- CHINE COMPANY, OF LA PORTE, INDIANA, A CORPORATION F INDIANA.
SLICING MACHINE Application filed May 10, 1928, Serial No. 276,555, and in the Netherlands June 9, 1927.
This invention relates to an actuating device for imparting reciprocating movement to a carriage of sub plate of machines for slicing food.
An obj ect of this invention is to replace the expensive gearing usually found in the kdrive of these machines with amore simplified and economical driving mechanism in which gearin@ is eliminated. Y
Fig. 1 is a plan view of the machine with parts broken away.
Fig. 2 is an end elevation as viewed from the left of Fig. 1. I
Rising from the bed plate 20 are brackets supporting the slide rods 22 and 23 upon which the carriage 1 isslidably mounted. The knife 12 is journaled in a bracket 21 and is driven through the engagement of a ratchet 9 with a chain 10'which in turn drives vthe chain 11 on the knife sprocket. The ratchet 9 engages the chain 10 only during the movement of the carriage 1 toward the knife, the ratchet sliding idly over the chain in the reverse direction. This arrangement saves the energy that would be wasted in reversing the direction of rotation of the knife at every back and forward movement of the carriage. The carriage is provided with guides 18 to slidably receive a meat table, movable by well known mechanism not shown, toward the plane of the knife. Bearings 13, 14 and 16 are secured to the frame of the machine and in the bearings 13 land 14 is journaled'a shaft 2 having a hand wheel 3 secured toits end.l The end of the shaft 2 opposite the wheel 3 has an angularly disposed part 2 which may be integral with the shaft 2 or it may be a'separately formed element. The bearing 16 alined with the bearings 18 and 14 slidingly and rotatably receives the shaft 17. The shaft 17 has an angular disposed end 15 similar to the end 2 on the shaft 2.
The faces on the angularly disposed portions 2 and 15 are parallel and extend from opposite sides of t-he common axis of the shafts 2 and 17. A crank pin 4 is normal to and connects the faces of the offset parts 2 and 15 and on the crank pin 4 is journaled the bearing hub 5 of a connecting rod 6. A pin orfroller 7 extends upward from the opposite end of the rod 6 through a slot 24 in the hed plate 20. The upper end of the roller'or pin 7 engages a recess 8 in the carriage 1. The recess 8 is sufficiently long to accommodate the movement of the pin 7 lin the direction of the recess, this motion of the pin 7 being due to the rotation of the end of the rod 6 about the common axis of the shafts 2 and 17. The pin pin 7 extends through an arcuate slot 24 formed in the bed plate 20.
When the hand wheel 3 is rotated, the end 5 of the connecting rod 6, in addition to its rotative movementaround the axis of the shaft 2 or 17, is constrained to follow the inclination of the faces on the offset parts 2, and lsince the rod is at all times held parallel with the offset parts 2 and 15. Considering Fig. 1, it will be seen that when the shaft 2 is given another half revolution, the offset parts 2 and 15 will be inclined so as to direct the rod 6 toward the other end of the slot. Revolving the hand wheel 3 therefore causes the carriage 1 to be reciprocated back andv forth past the edge of the slicing knife 12. I
Although I have illustrated a specific embodiment of myinvention, I donot wish to be limited to the particular details shown. An effect similar to that obtained in the illustrated apparatus may be attained by securing on the shaft an angular disc co-operating with a lug or roller on the carriageor 'by mounting upon the shaft a drum which is provided with a helical groove or rib which, however, is closed in itself and which coopera-tes with la pin or'groove respectively onthe carriage. f
