Abstract: 205,331. Golby, F. W., (U. S. Slicing Machine Co.). Oct. 9,1922. Cutting slices in succession.-In a machine for slicing bread or the like, a disc-knife 25 rotates about its axis and bodily about an eccentric axis, the two rotations being opposed in direction, means for preventing the bodily rotation during grinding are provided and the loaf during the slicing passes through apertures in the knifecasing. Frames support bearings for a shaft 14, enclosed in a sleeve 27 and actuated by a hand-wheel 15, which is connected with an arm 31 by a counterbalance weight 34. The arm 31 rotates on a shaft 29, having a crank-handle 41 and a coaxial spur-wheel 30, which is normally locked against rotation by engaging a screw 43 with a recess 45 in the casing 18. The knife 25 is journaled on the arm 31 and is rotated; during the rotation of the arm 31, by a pinion 37 and an idler pinion, the gear ratio being such that a different portion of the cutting edge first engages the loaf. At each slide the arm 31 is locked during grinding by a screw 117 which engages a cam 86, on the wheel 15, and the crank 41, being released, the knife is rotated by gears 30, 37 and the idler pinion at a greater speed than during the slicing. The top 112 of the casing is displaced to allow the grinder 115 to operate. A plate 109 presses against the knife and prevents crumbs &c. from entering the gear-space. The loaf 17 is fed along a guide 16 and is gripped in advance of a flange 50 on the feed-member 49 by pins 51 on the same and pins 52 on a lever 53 which is pressed down by a spring-member 56. The member 49 has brackets 57, 47 which engage a guide-bar 58 and the feedscrew 46 respectively. A spring-pressed pin on the spindle 60 engages the screw 46 and may be retracted by a wheel 61, pin 62 and cam-surface 63. The intermittent feed is derived from a bell-crank 83. Fig. 3, having a roller 84 which engages a groove 85 in the cam 86. The bellcrank 83 is connected to a lever 81 which is thereby oscillated and oscillates, by a link 80, a disc 78 which, with a cupped disc, encloses a ballclutch which rotates intermittently, through an intermediate pinion, a wheel 67 secured tc the feed spindle 46, retrograde movement being prevented by detents and ratchet-wheel 64. The slice thickness is adjusted by sliding the member 89, to which the link 80 is pivoted, along the lever 81, a rack and pinion being provided for this purpose. A pointer 99 and scale 98 indicates the slice thickness. The slices are stacked against a sliding member 103. The loaf is held near the cutting position by a spring-plate 100 and the door 106, which normally closes the loaf-receiving aperture in the knife-casing, is held in an elevated position by a spring-catch 108. Access to the gearing is permitted by removing the plate 110.

In the arrangement shown in Fig. 1, the network 12 comprises windings 15, connected to form a hexagon, and interconnected with star-connected windings 16, the network being connected to the circuit 10 through valves 20-31, which are preferably of the vapour electric discharge type. The grids of the valves are excited from a source of control potential 17 through a grid transformer 18, 19, the latter being preferably self-saturating or other means being provided for supplying the grids with an excitation of peaked wave form, as described in Specification 390,184. In order to commutate the current between the several valves under any desired power-factor conditions on the circuit 11, a commutating transformer 32 is connected between the D.C. circuit and the valves, and a harmonic commutating potential is introduced by means of a winding 35 energized from the circuit 17 through a frequency changer comprising a synchronous motor 36 driving a synchronous generator 37. In a modification, Fig. 2 (not shown), the geometrically rigid network comprises a group of windings connected to form a hexagon and two groups of delta-connected windings joining the middle points of alternate windings of the hexagon. In another arrangement, Fig. 3 (not shown), the hexagon is formed by the middle sections of two groups of delta-connected windings which are interconnected to form a symmetrical star. In another arrangement, Fig. 4 (not shown), each of the triangles of the network of Fig. 1 is subdivided by further windings connected between the mid-points of the triangles. The equivalent number of phases in the network may be increased by providing intermediate terminals on the windings. In one arrangement, Fig. 8, the intermediate terminals 54 are spaced to give 12 phases, while in Fig. 9 the equivalent of an 18-phase network is obtained by intermediate terminals 55, 56.
