Abstract: 371,431. Slicing- machines. DAYTON SCALE CO., 468, Huffman Avenue, Dayton, Ohio, U.S.A.-(Assignees of Wood, G. R.; 112, Westmount Avenue, Toronto, Canada.) Jan. 19,1931, No. 1735. Convention date, Jan. 22, 1930. [Class 28 (ii).] In a slicing-machine in which a gauge-plate or fence is used for regulating the slice thickness, the fence is supported by means which permit the insertion of a slicereceiving tray under the fence. As shown, the fence comprises a plate 52 advanced or retracted by mechanism housed in a casing which is supported by screws 38 from a frame 21 secured in cantilever fashion to the main frame 12. A slice-receiving tray may thus be interposed between the fence and the base 10. The fence casing may be steadied by a cranked member 60 extending from a vertical post 61 which with another post 63 supports a guide-bar 64 for the reciprocating carriage 66. The adjustment of the fence is effected by a knob 46 which, when pulled out against a spring 45, disengages a pointer 49 from a notched slice thickness scale 48 and is then free to revolve. Rotation of the knob 46 rotates the cam 42 on which rollers 50 carried by the fence 52 bear. The fence is guided and kept in engagement with the cam by plunger headed pins 56 which slide in casings 53 and are associated with compression springs 54. When adjustment has been effected, the knob 46 is allowed to move inwards, the cam then being locked by the engagement of the pointer 49 with the scale 48. The carriage 65 is guided by the rod 64 and a lower track 65 and is reciprocated by the handle 82 which is oscillated to effect the slice feed. The Specification as open to inspection under Sect. 91 (3) (a) states also that a roller journalled in the depending end 70 of the carriage 66 bears against the track 65 to prevent tilting of the carriage. The handle 82 is secured to a shaft 81. which is connected by a one-way ball clutch 83 with the gearing 101 which meshes with a rack 100 on the slice feed carriage. Stops 131 limit the extent of the oscillations and the ball clutch is disengaged by pressing in a knob 91. The substance to be sliced is rested in a trough-like member 78, 79 which may have a porcelain facing 125. It is gripped either by the " last-slice spikes of the clamp 115 or between the clamping spikes 119. The clamp 115 is pivotally mounted in an arm III and is frictionally held in any desired angular position. The arm 111 is pivoted to a feed carriage which is guided along rods 105, 107. The knife 17 is driven by a motor 11 and a belt 18 which wraps a pulley 16 on the back of the knife. The knife is sharpened by a stone 28 and a steel disc 29 removes the burr. The sharpening means are enclosed within the main casing 12, and to prevent grease &c. from being deposited on the stone whilst inoperative, it is enclosed in a casing 30 having a swinging closure 31 actuated by the knob 33. The stone is advanced to the grinding position by rotating the screwed journal sleeve 24 by a knob 26, and the disc 29 is similarly adjusted by a knob 26. This subject-matter does not appear in the Specification as accepted.
