Abstract: 769,914. Piling material; endless conveyers. JARUZA AKT.-GES., CHUR. May 21, 1953, No. 14361/53. Class 78 (1) and 78 (4). Material is fed to a stock-pile of circular plan by apparatus mounted on a central mast 1 and is withdrawn through apparatus disposed in a circle concentric with the pile. The pile may be confined by walls 9, Fig. 1, forming an outer inverted frustum of the cone and an inner cone on which is mounted a structure 1, 2, 4 supporting conveyers and shoots by which material is deposited in the path. Gates 10 controlling the withdrawal apertures lead to a circular tunnel which contains an annular platform 11 mounted by means of wheels 12 running on a circular rail 13 to move around the tunnel so as to convey material from the gates 10 to a plough 14 which discharges the material on to a conveyer 16. The pile is formed by a conveyer 5 mounted on a luffing jib 4 carried by a slewing structure 3 above which is mounted a spiral shoot 7 fed through a hopper 6 from a fixed conveyer 2. A gate 8 in the wall 9 is disposed so that, when the stock-pile is exhausted, material may be delivered directly from the conveyer 5 to the conveyer 16. The walls 9 may be omitted and the material piled on a flat surface and more than one withdrawal tunnel and annular platform 11 may be arranged concentrically. A telescoping system of conveyers may be arranged on the jib 4. The platform 11 may be replaced by a train of independent platforms articulated in the ring. In an alternative construction a conveyer is mounted beneath the stock-pile so that it may be turned to register with any of a series of radial tunnels beneath the pile. It may then be moved along the tunnel to receive material from gates in the roof of the tunnel and deliver it to a central shoot. Specification 762,278 is referred to.

Title: Improvements in cutting-machines for leather and the like
IPC: C14B5/00
Filed: 1922-05-23
Abstract: 204,089. Sawyer, C. A. May 23, 1922. Cutting-out apparatus.-Relates to sole-blank cutting presses wherein the leather strips are fed by an endless belt or chain having an intermittent feed to the cutting-head, and comprises means for preventing overthrow of the feeding mechanism at the end of its stroke, adjusting means to enable cross-bars, which carry the work, to be kept parallel and perpendicular to the line of travel of the chain, and means for positioning and guiding the work passing to the cutters. A vertically reciprocating cutter head 15, driven in the usual manner, is supported on a pair of standards 11 mounted on a base 10. A pair of endless chains 72 are led over five pairs of sprockets 53, 69, 68, 55, 59, the pair 59 at the rear of the machine being mounted on a pivoted spring-pressed arm 57 to tension the chains; while the two pairs 68, 69 at the front are mounted in an extension 65 of a top frame 64 extending the length of the machine, pivoting about the rear sprocket shaft 54, and adjustably supported by studs 71 at the front end. An operating handle, not shown, prevents its detachment or displacement in the clamp as it turns, and a further guiding plate 116 removes the natural bend of the leather and passes it under the cutters. In order to prevent the relative displacement of the leather and the cutters by the inertia of the moving parts at the end of the feeding stroke, a friction brake is provided on the shaft 66 of the front sprocket 68. This brake consists of a stationary member 123 mounted on the shaft and having an extension 138, Fig. 8, bearing against the frame, while two discs, one on either side of the stationary member, and separated therefrom by leather discs, revolve with the shaft. one being adjustably mounted thereon to give the desired degree of freedom. As the cross-bars 74 pass over the cutting bed, a shoe 134, pivotally mounted on the top rail 119 by bell-crank levers 131 at each end, is alternately raised and lowered, this motion being transmitted through a bellcrank lever 137 to a sliding spring-pressed rod 37 which moves a cam-roller 45 into and out of the path of a cam 47 on the shaft 25 of the pinion 24. This cam-roller is mounted on a stub shaft secured to the shaft 27 operating the clutch-fork 28, hence should a cross-bar remain over the cutting bed, the cam-roll remains in the path of the cam, which is timed to withdraw the clutch before the cutters can descend.

Title: Improvements in and relating to Electric Furnaces.
IPC: H05B7/00
Filed: 1918-09-20
Abstract: 131,767. British Thomson - Houston Co., (General Electric Co.). Sept. 20, 1918. Electrode furnaces.-A regulator responding to changes in the current or pressure in a furnace is also controlled automatically in accordance with the temperature of the furnace, so that when the furnace or charge is cold, the regulator maintains a larger power input. In the arrangement shown, a thermo-couple 54 in the furnace, in the charges, or in the heater itself is connected, to a galvanometer 56. The pointer 57 of the galvanometer is supplied with direct current at intervals by a reciprocating blade 68, and moves between stationary contacts 66, 67, connected to reverse field coils 63, 63<1> of a motor 62. A cut-out 71 in series with the motor is provided with a dash-pot retarding closure of the circuit again. A switch arm 61 is moved one step at a time by the motor 62, so as to cut in or out sections of a resistance 58 in shunt to the primary operating electro-magnet 12 of the regulator, which thus responds to increased or diminished values of the current in a transformer 13 excited by the furnace current. The electro-magnet 12 closes a circuit from auxiliary mains 30 through a relay magnet 18 or 19, to send current in either direction through a motor 4 adjusting an electrode 3. When the current to this motor is cut off, a magnet 48 connected to the armature closes another circuit through the armature and a braking resistance 50. Interlocks 51 - - 53 prevent closure of the supply circuit and braking circuit simultaneously. A second upper electrode 3<1> is regulated by another motor, the circuit of which is controlled by a primaryelectro-magnet 20 in shunt between this upper electrode and the hearth or charge. A resistance 40 shunts the first electrode 3 and the hearth so as to allow current to reach the electro-magnet 20 when the arcs are broken. An electro-magnetic switch 26 opens the control circuits if the supply fails.
