Abstract: 267,152. Saio, A. March 6, 1926, [Convention date]. Cutting slices in succession.-In a disc knife reciprocating table slicing-machine of the kind in which the guiding and driving-mechanism for the reciprocating carriage is enclosed in a hollow base frame provided with a cover, and the feed screw is positioned beneath the reciprocating table, the guides for the carriage consist of two parallel cylindrical rods secured in position at their ends in recesses in the frame of the machine and in the removable cover, the cover and frame being joined in a plane passing through the axes of the guide rods, and an element which supports the stop for the feed ratchet is slidable on one of the guide rods. As shown in Fig. 3, the table 1 is carried on sleeve members 2, 2<1> slidable on guide rods 3 housed within the frame 4 the sleeve 2 having a projection which is secured to one side of the table 1 and reciprocates in a slot in the side of the frame 4, whilst the sleeve 2' has an upwardly projecting portion which reciprocates in a slot in the frame cover 15 and supports the other side of the table 1. The connecting-rod 5 is connected to the sleeve 2 which has considerably more bearing surface than the sleeve 2<1>. The knife 11 is driven through bevels, sprockets and chain, a tensioning- jockey being provided. The meat is placed directly on the meat table 10 or upon a plate adapted to slide between the flanges 14 of the table 10. The feed screw 16 is journaled in brackets 1<1>, depending from the underside of the table 1, and has a ratchet wheel 21 freely revoluble thereon. The non-circular end 16<1> of the screw 16 is engaged by a correspondingly shaped sleeve 22 slidable thereon and pressed into engagement therewith by a spring 23. The sleeve 22 has a serrated end which engages similar serrations on the boss of the ratchet wheel 1. By this means, the ratchet wheel 21 is coupled to the screw 16 unless the sleeve 22 is pulled back by the knob 22<1> to effect hand adjustments &c. A pawl lever 24, under the influence of a spring 20, oscillates on the screw 16 and contacts with a stop 27 which is slidable on a guide rod 3 and is adjustable, for slice-thickness regulation, by rack and pinion gear operated by a graduated hand-wheel 30, the graduations being visible through a window in a member 31<11>. Rotation of the stop 27 on the rod 3 is prevented by a projection 28<1> which works in a slot in the frame 4. The feed nut segment is disengaged, against spring pressure, by a revoluble member having an inclined cam face co-operating with a similar cam face on the meat table. The meat clamp comprises posts 32, 32<1> mounted at opposite corners of the meat table 10, sleeves 33<1>, 35<1> slidable on the posts and locked thereon by the upward pressure of the meat forcing cam-faced members 37, Fig. 4, pivoted to the lifting-handles 36 and forming parts thereof, into frictional locking contact with the posts. Springs 39 tend to press the members 37 downwardly. The clamp 35 is pivoted to the sleeve 35<1> and is connected by a ball and socket joint 34 to an arm 33 projecting from the sleeve 33<1>.
