Abstract: 372,330. Slicing-machines. DAYTON SCALE CO., 468, Huffman Avenue, Dayton, Ohio, U.S.A.-(Assignees of Peddicord, P. G. ; 468, Huffman Avenue, Dayton, Ohio, U.S.A.) Jan. 27, 1931, No. 2688. Convention date, Feb. 1, 1930. [Class 28 (ii).] Refers to the clamping means for a slicing machine and is described with reference to a disc knife machine with a handreciprocated carriage and hand-f e e din g means for moving the meat against an adjustable gauge plate or fence. As shown in Fig. 1, the reciprocating carriage 80 is slidable along a guide-bar 78 and is prevented from rotating thereon by the engagement of a guide 72 with a rail 79. The meat is clamped between two spiked plates 88, 92 which are connected together to move in unison towards the slicing plane. The spiked plate 88 slides over a porcelain plate 91 and is secured by screws 89 to a ledge 90 of a carriage having rollers 87 engaging with a guide rail 85. The carriage supports a bracket 86 in which the rod 96 for adjusting the plate 92 is slidably mounted. The reciprocating carriage 80 is actuated by the handle 84 and the slice feed is effected by pressing on the handle 99. The rod 96 is slidable in a sleeve 97 on the bracket 86 and is secured in its uppermost position by a spring- pressed lever 109 engaging a notch 110, Fig. 3, on the side of the rod. This lever 109 is released by pressing with the thumb on the end 107 whilst the handle 99 is being manipulated. The spiked plate 92 is secured to a rod 93 which is pivoted at 94 in a recess in the lower end of the rod 96. The plate 92 has two operative positions, one vertical for engaging the end of the meat and the other horizontal for engaging the top. It is engaged in either of these positions by a pivoted latch member 104 which is pressed by a spring 103 in both positions to engage the rod 93 in locking position. The horizontal position of the rod 93 is determined by a stop 98 thereon engaging with the end of the handle 99. In a modification of the clamp the bracket 86 is replaced by linkage, the pivot pins of which are provided with adjustable friction means for maintaining the linkage in any desired adjusted position. The knife 17 is provided with a pulley 16 at its rear side and is driven by a belt 18 from a motor 11. The knife is provided with a coverplate 22 which is secured to the machine frame by bolts 23, 24. The slice thickness adjustment of the fence or gauge plate 60 is effected by the rotation of a sleeve 65 by a handle 66, this sleeve carrying a number of cam surfaces 56 which engage rollers 58 mounted on the back of the gauge plate. The gauge plate carries, on its rear side, sleeves 61 which slidably engage plungers 64. Coiled springs 63 are fitted under the heads of the plungers 64 and tend continually to withdraw the gauge plate from the cutting plane. The tendency of the. springs to rotate the cams 56 and the handle 66 therewith is overcome by spring-pressed pads frictionally engaging the flat rear surfaces of the cam member. The gauge plate is supported in cantilever fashion by a frame 20 secured by screws 21 to the main frame 12, Fig. 6, thereby allowing the slice receiving tray to rest thereunder. The slice deflector 116, Fig. 6, is carried by a stud 118 extending from the frame 12, the deflector being slidable on the stud but normally clamped thereto by a set-screw 119. The Specification as open to inspection under Sect. 91 (3) (a) states that the bolt 24 has a button head which is turnable to align with a slot in the plate 22, in which position the plate 22 may be slipped off. Additional support may be given to the gauge plate by a cranked member 122, Fig. 2. The knife is cleaned by a scraper secured to the frame 12 but concealed from view by the cover-plate. A scrap pan may be positioned beneath the scraper. The rear of the knife 17 is enclosed in a housing containing grinding means. These means comprise a grindstone 30 and burr-removing disc 38. The grindstone 30 is journalled in a screwed sleeve 28 having an adjusting knob 31 at its outer end. The stone is advanced towards the knife by rotating the knob 31 and during its rotation a trigger 41 contacts with a pin 40 on a disc 39 mounted on a shaft 38 carrying a cover 35 for the dirt-excluding housing 34 for the grindstone. The cover 35 is thus swung out of the way to allow the grindstone 30 to emerge from the housing 34 into the grinding position. When the stone is retracted the trigger 41 acts in the reverse manner upon a pin 401 to swing the cover 35 into the closing position. In a modification, Fig. 9 (Cancelled), the trigger and pin cover-operating mechanism is enclosed within the housing 34. The burrremover 38 is also moved towards or away from the knife by a screwed sleeve. This subject-matter does not appear in the Specification as accepted.
