Filed: 1926-10-20
Abstract: 265,508. Sp³hl, E., and Sp³hl, J. Oct. 20, 1926. Angular bending; twisting wires together.-A machine for twisting the ends of upholstery springs round the last coil and forming a kink beyond the knot, as shown in the left-hand portion of Fig. 5, comprises a movable clamp member 11 adapted to engage the second coil 8 of the opening 6 beyond the knot and urged upwardly at a predetermined time during the twisting of the knot, the first coil 7 of the spring being held down on a fixed clamping member 10 by a pivoted clamping member 9. The second coil 8 of the spring is located in a notch 19 in the clamping member 11 which is pivoted to the table 15 and rests on a stop 20. A recess 21 in the clamp member 11 is engaged by a nut 1 with adjustable bolt 18 having a spherical lower end entering a socket 2'2 on a bell-crank lever 5 carrying a roller 24 co-acting with a cam 4 on the main shaft 1. The knotting wheel 7 is driven by a wheel 3 on the shaft 1. The clamping member 9 which holds the first coil 7 of the spring down on the fixed member 10 is actuated by a treadle rod 13 and lever 12. After the knot has been partly twisted the cam 4 actuates the movable clamp member 11 and forms a kink beyond the knot: the height, c of the kink may be varied by adjusting the bolt 18 in the nut 17.

Filed: 1950-10-30
Abstract: 706,695. Toasting apparatus SIMPLEX ELECTRIC CO., Ltd. Jan. 29, 1952 [Oct. 30, 1950], No. 26406/50. Class 28(1) In toasting slices on edge on a conveyer in which the slices are conveyed between radiant heaters 19, the dropping of the slices through a hopper 35 on to the conveyer 16 is controlled by a shutter which may be in the form of an apertured drum 36, Fig. 5, rotated in timed relation with the conveyer so that the slices cannot be overlapped on the conveyer. The arcuate parts 38 of the shutter drum 36 normally span and close the openings in the toasting chamber 18 to prevent loss of heat upwards. When the drum is rotated to open position a slice in the hopper is allowed to drop through on to the conveyer 16 being guided by wires 33, and then is conveyed forward by pusher arms 70 on the conveyer chain. The arms 70 are channeled to receive the slice edge and hold it vertical. The drum is rotated from the sprocket and shaft 47 of the conveyer through a cam and connecting rod 50. The conveyer &c. is driven by an electric motor 42 through two worm reduction gears 42, 43. The motor is housed in a lower compartment under a crumb tray 26. The endless conveyer, Fig. 4, has rollers 62 running on a support rail 61 on its upper run. Crumbs are deflected into the crumb tray 26 by shedding plates 73. Other crumbshedding plates 77 are provided beneath the heaters 19. Current is picked up from bus bars 69. Heat loss is minimized by an inverted U-shaped casing 22 containing asbestos lagging 23. The heating elements may be carried in slots in depending supports. They are arranged to provide a variation in heat distribution. At the inlet end they occupy the lower 1/3 to 2/3 of the total height of the chamber and then diverge to occupy the full height. Baffles 81 reduce the amount of heat applied to the leading edge of the bread slice to prevent it being over-toasted. Guide wires prevent the slices from inclining towards the heaters. The lower chamber may be used for control devices, fuses, an indicator light 88, mechanical or electrical speed control for the motor 40 and a thermostat, all with exterior control knobs.

Abstract: 260,613. Fostinis, E. Oct. 31, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Machines, utilizing inertia to obtain movements in.-The apparatus is stated to be for the purpose of augmenting the power developed by a motor of any kind by utilizing the centrifugal force of an eccentrically loaded disc driven by the motor. In the apparatus shown in Fig. 1, electric motors E, E<1> drive discs A, A<11> eccentrically loaded by weights D, D<1> and geared together by a wheel A<1>. The discs A, A<11> are mounted on a pivoted beam C which is oscillated by the centrifugal pull of the weights, the movement being transmitted by segments through free-wheels to a shaft I. In the device shown in Fig. 2, the, apparatus of Fig. 1 is modified by mounting the beam U on a gear-wheel L which meshes with a gear-wheel G on a shaft I, ratchet wheels being interposed which inhibit rotation in one direction so that the beam C is compelled to revolve. The motor E in this modification drives the wheel A<1>. In the device shown in Fig. 4, weights D, D<1> rotated by a motor E through bevel gearing reciprocate a carriage M which rotates a shaft I through ratchet wheels G. In the device shown in Fig. 6, a mass D rotated in a horizontal plane reciprocates a carriage M running in a groove Q.

Abstract: 816,477. Centrifugal separators; washing granular materials. DORR-OLIVER Inc. Sept. 23, 1955 [Sept. 23, 1954], No. 27167/55. Classes 23 and 82(2) A separation system comprises at least one hydrocyclone stage having a pump (14), a hydrocyclone unit (18) with a feed inlet and at least two discharge conduits (20, 22), a conduit (16) leading from the exhaust of said pump to the feed inlet of said cyclone unit, a pump supply conduit (12) for delivering to the intake of said pump a liquid-borne feed material for separation; a wash liquid conduit (44) for supplying wash liquor to the stage said conduit being in hydraulic communication with one of said discharge conduits (22), and an " isolation leg " conduit (28) connecting the wash liquid conduit to said pump supply conduit for passing wash liquid and recirculating the cyclone unit discharge from said discharge conduit (22) to the pump intake, thus maintaining the rate of flow from the pump substantially constant. The " isolation leg" should have its length at least in excess of four times its internal diameter. Its function is to prevent direct passage of feed slurry into the wash liquid unless the feed exceeds the capacity of the separation system when the feed will flow in the leg countercurrent to the wash liquid; turbulence also is thus said to be reduced or prevented. Fig. 1 shows a diagrammatic arrangement of a two-stage system. Feed slurry enters at 10 and is pumped by pump 14 into cyclone 18; wash liquid also enters the pump from " isolation leg " 28. Overflow traction leaving at 22 discharges at 24 but a portion may recirculate via conduit 26 to leg 28. The underflow fraction at 20 enters a second stage having " isolation leg " 48 with wash liquid supply 30, pump 34 and cyclone 38 giving a final underflow fraction at 40, and an overflow serving as wash liquid 44 for the first stage, whilst a portion may re-circulate via conduit 46 and leg 48. In Fig. 2 feed slurry supplied at 111 reaches cyclone 118 via pump 114, underflow passing at 120 to the second stage pump 134 and cyclone 138, the overflow leaving at 122 and entering wash liquid conduit or header 130 to discharge at 124 or be part re-circulated in the " isolation legs " 128, 126.
