Abstract: 328,541. Berkel & Parnall's Slicing Machine Manufacturing Co., Ltd., and Thomas, H. Feb. 7, 1929. Divided on 328,966. Cutting slices in succession. - In a slicing- machine, the substance is gripped between lateral members of which at least one is adjustable laterally with its clamping-surface maintained parallel or approximately parallel to the line of feed so that it can exert a clamping pressure at any part of its length. The member may also be arranged for angular adjustment. As shown in Fig. 2, the meat is clamped on the feed table G between a last-slice holder 81, swung on an upright 82 into the side position, and a plate 85 which is movable bodily towards the holder 81 by levers 86, 87 pivoted at 88 to the feed table, the levers 87 being also pivoted at 87a to the plate 85. The lever 86 is pivoted to a block 89 slidable on a guide bar 90 and looked thereon by a friction ring which is releasable by a finger member 95. Angular adjustments of the plate are effected by rotating an eccentric pin 91 which is journaled in the levers 87 and is slidable in a slot 92 in the lever 86. The holder 81 is adjust. able into various angular positions in which its locating pin 83 engages one of a number of holes 83<a> in the table G. The holder 81 may be swung into the usual last slice holder position when desired. The holder 81 mav be made in flexible form as described in Specification 324,254, [Class 79 (v), Motor vehicles &c., Steering &c.]. In another modification, the adjustment of the levers 86, 87 is effected from the operator's side of the machine, a jointed rod, running across the machine, being pulled by the operator to move the levers and consequently the plate 85. A friction ring clutch prevents the jointed rod, and consequently the plate 85, from moving under the pressure of the meat, until the ring is released by the operator. The angular adjustment of the plate 85 is effected by an eccentric pin connection between one of the levers and the sliding block 89. In a further modification, the plate is constrained to move bodily in a straight line by a pin and slot arrangement, and by a bar sliding through a stationary guide. The levers carrying the plate are locked by a pivoted spring-pressed finger carried by one of the levers which frictionally, but releasably, engages a grooved circular member on one of the hinge pins between the levers. In Fig. 8, the plate 140 is carried by levers 141 - - 144 pivoted at 146 to the feed table and at 145 to the plate. Adjustment is effected by a rod 149 hinged at 147 to the levers 141, 142 and passing through the hinge pin 148 of the levers 143, 144. A screw clamp 150 clamps the rod 149 in its adjusted position in the pin 148. As shown in Fig. 10, a last sliceholder 161 is angularly adjustable on the upright 163 and is located by opposed toothed members 169, 170. The plate 160 may be of any suitable construction and is mounted on an upright 162. The members 160, 161. are carried on a U.shaped frame 164 extending beneath the undertable K, the limb 164<a> having a projection 165 which works in a guide. The feed screw L passes through a bearing 166, the feed nut being controlled by a handle 168. In a further modification, the meat may rest on the undertable, and a band or anti-friction rollers may be arranged in the face of the undertable to facilitate the feeding motion.
