Abstract: 368,062. Slicing - machines. RUBIN, A., 5326, Neosho Street, St.. Louis, Missouri, U.S.A. March 4, 1931, No. 6710. [Class 28 (ii).] In a slicing-machine, the food is supported on a reciprocating carriage and is fed intermittently towards the knife 16 which is in the form of an elongated. blade which is reciprocated longitudinally in guides by a swash-plate mechanism, described below, driven by the shaft 27. The knife 16 is disposed at an angle to the surface of the reciprocating table as shown in Fig. 2, and the guide members are formed in and secured to a part 15 of a plate 12 arranged flush with and extending upwardly from the edge of the machine base. As shown in Fig. 3, the knife 16 is guided in a recess in the part 15 in which it is confined by a back strip 21 and a cover strip 23, both strips being secured by bolts 22. The knife has an openended longitudinal slot 59 at its upper end and a transverse slot 46, also open-ended, at its lower end. The slot 46 is hooked over a pin 45 on the reciprocating rod 43 and the slot 59 is engaged by a pin 58 carried by an L-shaped member 56 which is clamped in position by a screw 61 which passes through an adjustment slot 60. In the position shown in Fig. 5, the member 56b is clamped so that the pin 58 remains in the slot 59 during the reciprocations of the knife. When it is desired to remove the knife, the member 56 is unclamped and pushed up so that the pin 58 leaves the slot 59. The knife is then free to tilt into the dotted line position, Fig. 2, in which position it may be freed from the pin 46. Finger holes 63 in the guide members facilitate the manipulation of the knife. The lower end of the rod 43 carries a fork 47 with a pin 48 having a transverse aperture into which projects an extension 50 of a yoke 40 which is prevented from rotating by lugs 52. The shaft 27 carries a flywheel 31 to the inner face of which is secured a member 33, having a skewed shaft portion 35. A sleeve 36 is carried on the shaft 35 and rollers 39, carried on the yoke 40, run between the flange 37 of the sleeve and a washer 38 screwed on to the sleeve and kept screwed up by a coil spring 53 anchored to the washer and to a nut 54 screwed on the end of the shaft 35. As the shaft 27 rotates, the yoke 40 wobbles and reciprocates the rod 43 and the knife 16 therewith.

Filed: 1946-03-05
Abstract: 609,075. Photo-electric machine control. HUGHES, W. March 5, 1946, No. 6836. [Class 40 (iii)] [Also in Group XII] To ensure that two machines are correctly positioned relatively to each other before operation as for example a coke guide and ram, the operating circuit of one is controlled by a relay system which operates only when a certain value of current flows in a relay control circuit due to a definite value of resistance having been inserted in this circuit by the correct relative positioning of the two machines. In the form shown in Fig. 1, machines 9 and 10, arranged to feed ovens 1 to 30, have contacts 35 and 36 which travel over resistors 6 and 7 connected in series by wire 8. A supply from trolley wire 3 passes through ammeter 12, through the resistors and is returned to trolley wire 2. When the two machines are opposite each other the current in the ammeter 12 is such that a disc 13 on the shaft of the ammeter is rotated until a slot 13a in it is aligned with a fixed slot 15a enabling light from a source 14 to impinge on a photo-cell 16, the current from which is amplified in a valve 17 to close a relay 18 and a switch 19 in the operating circuit of machine 10. The ammeter positions the disc correctly only when the machines are opposite each other although actual machine position does not affect it. In further embodiments the relay circuit is closed by a contact arm carried in the ammeter and the resistances are mounted on the machines, wiping contacts being operated by gearing carried by the machines and actuated from fixed rack gearing beside the track. Specification 565,865, [Group XII], is referred to.
