Abstract: 225,342. Berkel, C. F. M. van, and Thomas, H. Oct. 31, 1923. Cutting slices in succession. - In a slicing- machine, the meat table is guided by a narrow guide comprising a fixed surface and a spring- pressed displaceable surface whereby canting of the table is prevented and removal of the table is facilitated. In Fig. 4, the meat table 1 is provided with a tongue 3 which moves in a guide formed by the wall 5 of the under carriage, a sliding bar 13, supported by pins 14 projecting from the under carriage, and a movable plate 9, mounted on pins 10 carrying springs 11 which normally urge the plate 9 towards the under carriage. The plate 9 has a tongue 8 which engages the top face of the tongue 3 and is secured to an angle plate 9<a> which bears against the wall 5. The bar 13 is provided with recesses which engage projections 33 on the plate 9 which is displaced, as shown, for removal of the table 1, by sliding the bar 13 longitudinally. The bar 13 is recessed to engage, and is moved by, a lever on the shaft 15 which is operated by a handle retained in position by a spring-pressed detent engaging indentations in a quadrant. The shaft 15 carries an arm 18 which is connected by a bar 19 to a corresponding arm on a pivot shaft projecting from the under carriage. A small movement of the handle on the shaft 15 raises the bar 19 and lifts the feed nut, which is carried on a member 35 slidable on pillars 36, 37, without moving the plate 9, thereby allowing adjustment of the meat table. Further movement of the handle slides the bar 13 to an extent which raises the projections 33 out of the corresponding recesses and the plate 9 is displaced for removal of the table 1, as in Fig. 4. The arrangement may be modified by forming the tongue 3 on the under carriage and the plate 9 on the meat table, the releasing mechanism being carried by the meat table. In Fig. 8, the under carriage 2 carries a fixed tongue 40, flanged at 41 to engage a groove 42 in the table 1 and having a bevelled face 44 of a vertical slidable retaining plate 43 carried by the table 1 and operated bv wipers 50 which are carried on a shaft 51. The wipers 50 are disposed in recesses in the meat table and project through slots 46 in the plate 43 whereby they contact with adjusting-screws 48 and lift the plate 43 for removal of the table 1. The plate 43 may be raised by eccentrics on the shaft 15 and on the pivot shaft of the arm carrying the bar 19. The tongue 40 may be mounted on the meat table to engage a groove in the undercarriage which would carry the plate 43, the mechanism for moving the plate 43 being arranged in the undercarriage. The plate 43 may be arranged for lateral movement. In Fig. 9, the tongue 53 is circular in section and is secured to the under carriage by bolts 54. The meat table is formed with a curved seating 57 to engage the tongue, and a vertically displaceable, spring-pressed retaining-plate 58 also engages the tongue. In Figs. 11 and 12 the meat table 1 is provided with aT-shaped tongue 62 which is engaged on one side by a retaining- plate 63 disposed in a recess 68 in the under carriage, and on the other side by a retaining-plate 64. The plates 63, 64 are normally pressed, by springs 80, 85, against the tongue 62. The flanges 69, 74 prevent the meat table from lifting. The plates 63, 64 have cam faces 71, 76 which respectively engage with a pin 81 on the shaft 78, corresponding with the shaft 15, Fig. 4, and with a pin 84 nn the shaft 82 which together with the shaft 78 carries the feed-nut lifting-bar 19. Rotation of the shafts 78, 82 moves the plri'e,s 63, 64 against the springs and allows the meat table to be removed. In Fig. 13, two laterally displaceable. flanged retaining-plates 90 91, carried by the feed table, are pressed by springs 97, 98, on pins 92, 93, against the opposite flanges of a T-shaped tongue secured to the un.der carriage, and a lever 101 pivoted at 102 between the plates 90, 91 is provided with a lateral projection 103 which is engaged by means which swing the lever 101 about its pivot, thereby displacing the plates 90. 91 for removal of the meat table, the said means comprising a lever 104 pivoted on a shaft 105 and abutting against the projection 103, a spring-returned rod 106 engaging the lever 104 and an operating-lever 113 having a roller 115 vhich engages notches 110, 111 in a quadrant.
