Abstract: 380,124. Slicing-machines. DAYTON SEALE CO., 468, Huffman Avenue, Dayton, Ohio, U.S.A.-(Assignees of Breaden, C. E. ; 628, Yale Avenue, Dayton, Ohio, U.S.A.) June 10, 1931, No. 16938. Convention date, June 13, 1930. [Class 28 (ii).] In a slicing-machine having a disc knife 14 disposed parallel to a gauge plate or fence 33, an abutment plate or plates 45, 46 are disposed at the side of the knife opposite to the fence and in the plane of the knife to engage the article after it passes the rear of the knife to prevent movement of the article towards the knife. The centre of the knife is guarded by a plate 40 detachably secured by slotted lugs 83, to arms 19, 20 extending radially from the knifesupporting frame 18. The bottom is detachably secured by a slotted lug 88 to the frame 18. The plate 40 is held in position by spring- loaded headed pins 86 and by spring-loaded turnable pins 80 having heads which may be registered with the slots 82. The abutment plate 45 is removably secured to the frame 18 by latch members 90 and the abutment plate 46 forms the side of a housing 50 for the knifegrinding means, which comprise a grindstone 51 having a stem 52 screwed into the front of the housing and a burring-stone 54 having a stem 55 likewise screwed into the housing. Adjusting-knobs 53, 56 are provided. The housing 50 has an integral sleeve 57 rotatable and slidable on a stud 58 carried by ears 59 secured to the frame 18. The ears 59 each carry a plunger 62 which engage in notches 63 on opposite sides of the sleeve 57. The housing 50 is moved from the position in which the plate 46 is flush with the cutting edge of th knife 14 by withdrawing the right-hand plunger 62, Fig. 6, and rotating the housing away from the knife about the stud 58. The housing is then pushed along the stud 58 into the position shown in Fig. 6, and is again moved towards the knife in which position the housing is held by the left-hand plunger 62. The grinding means may then be engaged with the knife. The knife is cleaned by a scraper comprising a fibre block 66 which engages the knife, carried on a strip 65 fastened to a stud 67 rotatable on a pin 68. A leaf spring 69, fastened to the stud 67 presses the block against the knife. The stud 67 is set in position by a pin 70 engageable with a series of depressions in the supporting bracket 72 which is secured to the frame 18. A scrap pan 75 is slidably arranged beneath the scraper and is retained in position by a spring latch. The top of the knife is guarded by a tubular guard 93 pivoted at 92 and retained by a pin 95. The fence is adjustable by a handle 34 and is supported by the arm 19 to which it is bolted, and by a foot 32 carried by a post 26 which also supports a round rail guide 25 for the carriage 28. The slice-receiving tray 102 has an upstanding flange 101 which is held by the lower end of the slice deflector 96 which is slidable on a rod 98 and clamped by a screw 99. A protuberance 100 on the knife support produces a wedge action on the deflector to grip the receiver 102. A flat rail 27 under the round rail 25 assists in guiding the carriage 28. The knife is belt driven from a motor 11 and has a roller-bearing journal.
