Abstract: 1,136,210. Slicing and cutting machines. LAB-O-MATIC CORP. 20 June, 1967 [28 June, 1966], No. 28519/67. Heading A4C. A slicing machine for severing sections from a comestible work body, such as a meat body product, especialy one that has bones or is frozen, comprises a rectangularly-shaped support assembly B having vertically extending bosses 20 and 21 with openings 22 and 23, which rotatably support the knife assembly E and the product assembly D or G on shafts 36 and 67 respectively which are rotated at different speeds through the gears 80 and 81 by a reversible electric motor 51, and a vertically adjustable table C, with an aperture 144 in which is located the knife assembly. The knife assembly in the embodiment shown, comprises an annular blade 40 with a relatively thick cutting edge portion for example, defining an included angle of approximately 45 degrees (Fig. 13, not shown) detachably connected by screws (46) to a disc-shaped member 42, mounted by means of hub (43) so that it is skewed in respect to the axis of rotation of the shaft 36 to impart a "wobble" to the knife blade, and a deflector 47 for deflecting the slices or sections severed by the knife blade into a shoot or conveyer (not shown). The product carrier D comprises an annular base 70 and a vertically extending support frame 71 welded to it, whose side walls 73 converge towards each other and each have upper and lower pairs of spaced rails 75 extending horizontally thereacross to which are fixed different shaped receiving receptacles 90, 91 and 92 whose interior surfaces or surfaces are inclined so that they direct the work bodies downwardly through aligned openings in the base 70 on to the table C and rearwardly in a direction opposite to the direction of rotation of the product carrying assembly, and by virture of the sloping walls 73 in a direction radially outwardly of its axis of rotation. The receptacle 90 is a cylindrically-shaped chamber 95 and the receptacle 91 and 92 comprise stationary members 101 and 135 and movable members 102 and 136 which move from a retracted position to allow a work body to be positioned against the stationary member and a locked work holding position. Alternatively receptacle 92 (Fig. 10, not shown) can be adapted to be loaded from the front rather than the side by pivoting the door (136<SP>1</SP>) to the sides of the U-shaped stationary member (135<SP>1</SP>) at the lower end of the latter by pivot pins (141). The product carrier G comprises a horizontally disposed rectangularly-shaped member 251 to which is welded a vertically extending sleeve 252 adapted to be drivingly connected and supported by the shaft 67, a receptacle 255, the interior surfaces of which are slanted in the direction opposite to the direction of rotation of the assembly G, consisting of a stationary member 256 and a movable member 257 pivotally connected to the sleeve 252 by members 258 (259) and a releasable locking means 270 (Fig. 15, not shown). If desired or necessary a mechanically operated hold down device 180 may be used for urging the work bodies against the table C. The device may be operated manually by means of a foot pedal 178 and a handle 187 or automatically by a spring (Fig. 12, not shown) with one end fixed to the base 13 and the other end connected to a bearing means (194) carried by rod 172. One and more vertically extending stationary knives 150 carried by table B and projecting to the desired depth through arcuately slots (152, Fig. 7 not shown) in the table C may be provided to vertically cut the work bodies prior to then being sliced by the knife assembly E. The knife blade 40 may be sharpened by a sharpener 220 which includes an electric motor 220, a grinding wheel 223, an adjusting screw 224 for moving the grinding wheel toward and away from the blade and a handle 225 for reciprocating the wheel relative to the blade during the sharpening operation so that the grinding face moves in the plane of the lower surface of the blade. Reference has been directed by the Comptroller to Specification 1,057,052.
