IPC: A43D15/00
Filed: 1920-09-06
Abstract: 172,700. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Sept. 6, 1920. Lasting.-Machines for shaping shoe uppers to the shape of the last in which a length of binding material is used to secure the toe portion are organized so that mechanism of the machine acts to present an end of the binding length to the shoe and effects anchorage therein. The invention is shown applied to a hand-method lasting- machine of the type described in Specification 14453/97. The general arrangement is shown in Fig. 1 comprising an edge rest 10 and work rest 12 for the shoe in lasting and binding. Wire is looped by revolving apparatus within a bracket 101, then tacked by drivers 54, and passed round the toe as the shoe is lasted, then looped again as before and finally tacked and cut off. A driving-shaft has a toothed wheel 16 geared through an idler 20 to a wheel 18, which operates a shaft 22 through a one-revolution clutch 26, Fig. 3. The clutch is operated on drawing down a rod 29 attached to a treadle. The rod 29 operates telescopic parts 33, 32 urged apart by a light spring 36 but forced together by a strong spring 34 acting through a lever. When the rod 29 is drawn down, the part 32, bevelled as shown, releases a spring pivoted clutch 28 which then moves inwards to engage a projection 24 on the wheel 18 which revolves the shaft 22 till the clutch 28 again engages the part 32. This part is drawn down by a latch 38 which'is tripped as it passes a fixed pin 46. The part 32 then flies up again to engage the clutch 28. Wire is fed from a reel 80 past a spring friction device 90, Fig. 6, to prevent back-lash through a guide 89 to a spring gripping-device 104. This device is carried in a slide 72 reciprocated in fixed guides 82 by an arm 92, Fig. 5. The arm is oscillated by a pivoted lever and cam mechanism (not shown in the Figure) on the shaft 22. The wire passes. between fingers 107 on a rod 106 which is pressed upwards for the purpose into a cavity 70 in the slide 72 by a bell-crank 120, Fig. 1, operated by a cam 124 on the shaft 22. The fingers 107 are rotated by rack teeth 114 cam and lever driven from the sbaft 22 engaging a pinion 108 splined to the rod 106. The wire, twisted as shown in Fig. 6, is then tacked by drivers 54, Fig. 5, to the shoe, the tacks being fed from raceways indicated in Fig. 1 by a slide joined to a rod 126 on the bell-crank 120. The toe is then lasted and the wire drawn round. As the wire is engaged the second time by the fingers 107 it is drawn very taut across a spring pivoted anvil 132, Fig. 6, a part 134 of which engages beneath the wire in the path of a cutter 140 which severs it. Specifications 13609/12 and 15953/15 also are referred to.

Abstract: 917,549. Power steering. HEACOCK, F. H. July 10, 1961 [July 25, 1960], No. 25765/60. Class 79(5). A power-assisted steering gear for motor vehicles comprises a steering box housing in which is pivotally mounted a fluid pressure actuated cyclinder operatively connected to a pitman arm shaft which extends across the housing, there being a valve for controlling the supply of fluid to the cylinder unit mounted on or connected to the housing so as to be spaced apart from the cylinder unit. The steering gear comprises a steering shaft 14 having a worm co-operating with a threaded sleeve 15 contained within a steering box 10 to which is pivoted at 12 a double acting cyclinder 11 having a piston rod 13 pivoted at 21 to a lever 20 which is a forging integral with or connected to a shaft 19 connected to a pitman arm to which is connected the vehicle steering gear. A lever 22 is pivoted at 23 to the lever 20 and at 27 to the sleeve 15 and passes through a slot 25 in the lever 20 so that limited angular moves ment relative therewith is permitted. The lever 22 is pivotally connected to an actuating arm 26 of a control valve 16 which is disposed on the opposite side of the steering shaft to the cylinder 11 and may be mounted on the exterior of the housing or within the housing or, as shown, an extension thereof having a removable cover 18, and may be enclosed in a fluid-tight manner. The stuffing box 10 may comprise a fluid reservoir and fluid may be directed to the valve 16 by a pump or from a hydraulic accumulator and in the neutral position of the valve is returned to the reservoir. When the steering shaft 14 is rotated, the sleeve 15 moves the lever 22 relatively to the lever 20 thereby actuating the valve 16 and directing fluid to one side or other of the cylinder 11 through appropriate conduits thereby moving the lever 20 until the neutral position of the valve is again reached. In the event of a power failure, the sleeve 15 will operate the lever 20 from the limit positions of the relative movement between the levers 20 and 22 which may alternatively be achieved by a pin and slot connection therebetween. The pivotal connection between the levers 20 and 22 may alternatively be at the mid-length of lever 20 and the pivotal connection of the latter to sleeve 15 being at its end. The valve 16 may also be connected to a supplementary power cylinder acting on the steering linkage to provide additional power assistance.

Title: Improvements in or relating to means for operating a winch, windlass or like apparatus on ship board
IPC: B63H23/00
Filed: 1919-10-24
Abstract: 158,066. Beardmore, Sir W., Chorlton, A. E. L., and Doig, J. S. Oct. 24, 1919. Driving-arrangements for screw propellers. - The power of a marine internal-combustion engine can be proportioned between the propulsion of the vessel and the driving of a winch or windlass through suitable change-speed gear. Fig. 1 shows one arrangement in which the engine is divided into two power groups A, B, operating separate lengths of shaft which can be coupled by a clutch E. One end of the main crank-shaft is connected to the propeller G and the other to a change-speed gear K through a clutch J. The change-speed gear is controlled by hand-operated gear K<1> and drives a winch N through a safetyappliance M<1>, for example a slipping clutch. When both clutches E, J, are closed, the whole or any proportion of the engine power can be applied to drive the winch by regulating the feathering blades of the propeller from the setting-appliance H, thus varying the power absorbed in propulsion. Opening the clutch E causes the winch to be driven by the power group B, while the opening of the clutch J cuts out the winch and leaves the whole engine power available for propulsion. In a modified construction, the engine is composed of a single power group with a governor acting as a speed-regulator. In this case, the regulation of the blades of the propeller forms the sole means of varying the power supplied to the winch.

Filed: 1963-07-02
Abstract: 983,949. Automatic temperature control systems. OWENS-CORNING FIBERGLAS CORPORATION. July 2, 1963 [July 2,1962],Nc. 26255/63. Heading G3R. The temperature of a glass melting furnace is automatically maintained constant by a controllable rectifier assembly connected in the A.C. heating supply of the furnace and triggered by a signal of the same frequency as the A.C. supply but having a phase difference therewith representative of the temperature error signal. Fig. 2 shows this part of the temperature control system wherein a silicon controlled rectifier assembly 88 comprises rectifier pairs 90, 91 and 92, 93 controlled respectively by the secondary windings 86b, 86c of a transformer 86 whose primary winding 86a forms part of a circuit including a secondary winding of a transformer 85 whose primary is energized from the A.C. heating supply and including the output windings of an auto-self excited parallel magnetic amplifier 84 whose control winding is supplied at 80, 82 with D.C. signal proportional to the temperature error. This signal controls the time, in each half cycle of the voltage applied from the transformer 85, at which the amplifier 84 becomes conductive to initiate a pulse in transformer 86, which pulse causes an appropriate rectifier pair to conduct. The potential distribution across the assembly 88 is controlled by resistors R 1 ---R 4 , capacitors C 1 ---C 4  acting as transient suppressors and C 1  C 3  also coupling the firing pulse of rectifiers 90, 92 to rectifiers 91, 93. Each pair of rectifiers controls the proportion of one half of each cycle of an A.C. supply 60, 62 allowed to flow through the primary winding of a transformer whose secondary supplies low voltage heating current to a feeder containing molten glass, Fig. 1 (not shown). Operation of rectifiers 90, 91 for example, occurs when the voltage drop across resistor R 1  is sufficient to fire rectifier 90, consequent discharge of capacitor C 1  producing current through a coupling resistor R 5  which, with the voltage across resistor R 2 , fires the rectifier 91. Voltage stability is effected by feedback to the input of the amplifier supplying the error signal at 80, 82, this feedback being provided by members 104,106 and an integrator network. The other elements of the temperature control system are conventional, and the level of molten glass in the feeder is automatically controlled by a variable speed motor driving the mechanism supplying marbles to the feeder, Fig. 1 (not shown).
