Abstract: 1,169,269. Interleaving sliced products. SWIFT & CO. 22 Sept., 1967 [25 Oct., 1966], No. 43217/67. Heading A4C. [Also in Division B8] In a machine for interleaving materials sliced at high speed the material (specifically bacon) is successively severed by a rotatory knife 12 of a bacon slicer 10 having a slab feed 11, from a first edge to a second edge of said slab, and then thrown forwardly to a take-off conveyer 16 in a shingled configuration. A frame 26 inclined at an angle upwardly from a point between the knife and the take off conveyer supports the interleaver 25, and on this frame is centrally located a spool 29 of interleaving material 30 from which the interleaving material is guided by the idler roller 31 and continuously drawn by a pair of power driven feed rolls 39, 40 that are mounted beyond the idler roll 31. A stationary anvil blade (54) mounted on 1,169,279. Vehicle seats. G. GRAMMER [trading as FIRMA WILLIBALD GRAMMER]. 31 March, 1967, No. 14795/67. Heading A4U. A tractor seat 10 is resiliently suspended by a pair of rubber rings 21, 22 extending between a fixed point on a base 3 and a rod 28 having a roller 29 which engages in a groove 30 in an inclined arm 7<SP>1</SP> of a two armed lever 7 pivoted by a pin 6 to a housing (5). The other arm 7<SP>11</SP> of the lever 7 is longer than the first arm 7<SP>1</SP> and is part of a parallelogram linkage supporting a support 9 for the bucket seat 10, and consesaid frame parallel to and beyond said feed rolls and a driven rotatable blade (55) co-operating with (54) shear interleaves from said stock fed from said feed rolls. The driven blade is connected to the slicer knife drive via a correction transmission unit 79 so as to be rotatable at a frequency proportional to the rate of rotation of said slicer blade and so as to allow the timing between the knives to be varied. A pair of ejector pinch rolls 59, 60 beyond said driven blade driven at a speed greater than the speed of said driven blade ensure that each severed interleaf is accelerated downward into the path of slices leaving said slicer knife, contacting the forward face of each slice. quently when the seat 10 is depressed the rubber rings 21, 22 are tightened. The tension of the rubber rings is adjusted by a control arm 33 which is pivoted at its lower end 34 to the base and at its upper end abuts a pair of guide rollers (31, 32) on the rod 28 on which the rubber rings are suspended. When the control arm 33 is pivoted by a threaded spindle 37 and a nut 36 pivoted to the control arm the roller 29 moves along the groove 30 in the inclined arm 7<SP>1</SP>. A pointer 39 on the control rod extends through a slot in the housing to indicate the tension of the rubber rings. The seat 10 is pivoted by means of brackets (45) to the ends of rods 42 which are slidable in pipes 41 welded to the support 9 and a projection (43) on the lower side of the seat engages one or another of a series of holes (44) in the support 9 to hold the seat in selected position. The front of the seat has a recess 46 into which the housing (5) projects when the seat is depressed. A piston and cylinder damper 26 and two rubber buffers 19, 40 are provided.
