Title: Improvements relating to slicing machines
IPC: B23Q11/08
Filed: 1927-10-15
Abstract: 279,112. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen. Oct. 15, 1926, [Convention date]. Cutting slices in succession.-The feed table of a slicing-machine is movable across the under table and is positively constrained against skewing or lifting by guides, one of which is axially fixed and another of which is movable and is characterized by the fixed guide being in the form of a tubular casing which embraces or substantially embraces the movable guide, or is embraced thereby. As shown in Figs. I. and IV., the feed table 1 is detachably locked to a guide block 17 by a revoluble handle 16 having a wedgepiece 16<1> engaging in a recess in the block which is accurately positioned by upstanding pins on the block registering with holes in the feed table. The block embraces a casing 18 substantially surrounding the feed screw 2 and secured at its ends to brackets on the under table, the bracket remote from the knife, if desired, being shaped to allow the feed table, in its rearmost position, to overhang the feed table. The feed nut 3 slides in a slot 22 in the casing 18 and is carried on a bell-crank lever 3<1> pivoted on a bolt 8 and engaged by the tapered end of a sliding rod and which has a square collar 5 to prevent rotation, and is pressed towards the bell crank by a spring 7. When the rod 4 is pulled back by the handle 13, a spring 6, bearing on an arm of the bell crank, disengages the feed nut. When the rod 4 is released, the tapered end engages the bell crank and re-engages the feed nut against the action of the spring 6. The block 7 is split and play between it and the casing 18 is removed by bolts of which the bolt 8 is one. The side of the feed table remote from the feed screw is prevented from lifting by a resilient angle plate 15 which engages a groove in the side of the feed table. In a modification, the feed screw is tubular and a guide rod, supported by brackets on the feed table, slides through it. In a further modification. Fig. VII, the feed screw is journaled in brackets on the under table which also carries a slotted cylindrical guide 26 engaged by a correspondingly formed guide surface 27 on the meat table. In any of the modifications the guide surface may be non-circular in section, and the embracing member, instead of being continuous, mav be formed in two or more spaced parts. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification similar to that shown in Fig. VII., except that a stationary guide bar secured to the under table parallel to the feed screw is completely embraced by a tubular portion of the feed table. This subject-matter does not appear in the Specification as accepted.
