<p>344,553. Slicing-machines for bread &c. LITTLEFIELD, C., Merrill Park, Battle Creek, Michigan, U.S.A. Dec. 16, 1929, No. 38548. [Class 5 (i).] Comprises a slicing-machine having a slicing table and sets of spaced blades arranged in crossed relationship and means for reciprocating and rocking the sets of blades. Frames 1, Fig. 4, are held together by cross members 2, 3 on which is mounted a horizontal table formed from strips 6; the articles to be sliced are moved along this table by means of flights 5, mounted on a moving band 4 and projecting through slots in the table. Tables 7 are arranged at each side of the machine for feed purposes and guides 8, 9 are provided, of which guide 8 extends rearwardly to form a stop. The conveyer is driven with a step by step movement by means of chain drive 20 from the geneva gear 19. Each set of blades is mounted in a frame 46, Fig. 5, having cross-bars 40, 41 and blades are kept in tension by means of springs; the frame is pivoted to levers 43 on shafts 44, 45. Shaft 45 is rocked by means of a lever 49 connected by a link 48 to a crank, so that the blades are given a reciprocating and a slight rocking movement. The article leaves the endless band and is engaged by fingers 71 attached to an arm 72 pivoted at 73 to a lever 74 and also by fingers 59 mounted on a plunger 36 which feeds the loaves along the slicing table 37 past the knives on to the receiving table 39. The plunger 36 is mounted to move horizontally in blocks 61 mounted on vertical slide bars 62. The plunger is given a horizontal movement by bellcrank lever 67 and a vertical movement by a bellcrank lever 63, the levers being rocked by a cam 66. The plunger thus moves in an elliptical path, the fingers being lifted clear of the next loaf on the return stroke. The plunger and carriage are actuated in timed relationship. An arm 81 attached to the plunger engages a stop 82 on a lever 79 on the working stroke and rocks the lever 72 so that the fingers 71 move with the loaf being cut. The holders 60 for the reception of the cut loaf are mounted on a right and left handed screw 87 fitted with a hand-wheel 89 by which their position may be adjusted. To afford access to the cutters the frame 83 carrying the slotted slicing table 37 is pivoted at 84 so that it may be swung clear and the fingers 71 may be moved away by means of the lever 79. The Specification gives details of a clutch and driving mechanism.</p> |
