Title: Improvements in apparatus for operating electric lifts
IPC: B66B1/42
Filed: 1926-10-28
Abstract: 279,634. Etchells, Congdon, & Muir, Ltd., and Muir, F. Oct. 28, 1928. Electric plant.-In an electric lift the main driving shaft A from the motor A is connected to the shaft D of the hoisting drum by a magnetic clutch M and also by spur reducing gear B, F, E, G, or chain reducing gear, which is brought into operation by a magnetic clutch N which is energized as soon as the clutch M is de-energized. An annular disc m which forms the centre member of the clutch M is secured to the gear B which is fast on the shaft A. The magnet casing of the clutch is keyed to the shaft D and can slide thereon, and carries the armature m'. The disc n of the clutch N is secured to the rear of the magnet casing of the clutch M, and the magnet casing of this clutch is secured to the gear G which is free on the shaft D. When only the clutch H is energized, the shafts A, D rotate together at the same speed. When the clutch M is de-energized and the clutch N is energized, the shaft D is driven at a slow speed from the gear B, through the gears F, E, G, clutch N and the magnet casing of the clutch M. Two cone or other friction clutches actuated by solenoids may be substituted for the magnetic clutches. In a modification, Fig. 6, the magnet casing of the clutch M is keyed to the shaft A, and the disc m is secured to a spider S keyed to the shaft D. The magnet casing of the clutch N is free on the shaft D and the disc n is secured to the spider S. The gear G is free on the shaft D. The spider and discs may be replaced by a double cone clutch, the movable members of which are operated by solenoids. The clutch M is energized simultaneously with the main controller. On approaching the floor at which it is desired to stop, a discriminating clutch relay is energized, which disconnects the high speed clutch and simultaneously puts into operation the low speed clutch.

Title: Device for operating automatically a telephone dial
IPC: H04M1/274
Filed: 1954-09-24
Abstract: 768,955. Impulse transmitters. DEMEULE-NAERE, M., and DEMEULENAERE, R. Sept. 24, 1954 [Oct. 10, 1953], No. 27624/54. Class 40 (4). Trains of impulses representing a predetermined multi-digit number are transmitted by a normal telephone dial-type impulse transmitter under the control of a device in which the number has been registered by a dialling operation, this dialling operation also serving to cancel any number previously registered in the device. As shown, the device comprises a plurality of buttons 43, each carrying on its shaft nine stops 15, Fig. 9. During the operation of the device, a shaft 1 is driven by an electric motor (not shown). This rotates, through a gear train, a depressed button 43 until it is stopped by the engagement of one of the stops 15 with a projection 14 on a plate 13, the shaft 1 then driving a finger 41 which is in engagement with the normal telephone dial. When the rotations of the button 43 and the dial total one complete revolution, an arrangement of cams disconnects the shaft 1 from the motor and withdraws the plate 13 from the path of the stops 15. The dial returns to its normal position, driving the button 43 to complete one revolution, whereupon it rises one step on an escapement 79 and the process is repeated under the control of the next stop 15, and so on until nine steps have been completed. To set the stops 15 to the required positions, they are set free to rotate on their shaft by slightly unscrewing the button 43 which is then depressed. The first digit of the required number is dialled on a finger-plate 91, which drives the button 43 through the same angle in the reverse direction. When the operator's finger reaches and depresses the finger-stop 101, Fig. 1, the motor is started and drives the button 43 through one revolution in the forward direction. During this process the first stop 15 is stopped by a projection 14, which is withdrawn on completion of the motordriven revolution of the button 43. The operator then releases the dial which returns to normal, driving the button 43 with its stops 15 through the same angle in the forward direction. The button 43 advances up the escapement 79 as before, and each stop 15 is set in turn by means of the finger-plate 91. Finally, the button 43 is screwed up to hold the stops 15 in the positions to which they have been set. If fewer than nine digits are required to be set, the finger-plate 91 is held stationary during the unwanted steps of the button 43, the circuit of the motor being maintained by pressure on the finger-stop 101.

Abstract: 749,979. Subaqueous structures; piles. MAUNSELL, G. A. Sept. 27, 1954. No. 27848/54. Class 68(2) A structure such as a section of an underwater subway S is anchored to the bed of a river or estuary by pitching a pile P above the water level H, passing it through the water so as to pass through a hole which is preformed in the structure, thereafter passing the pile through water and into the ground K, the pile being subsequently rigidly connected to the structure and the portion which protrudes above the structure being cut off underwater. As shown the section S of a subway has galleries F, G in which men can work at atmospheric pressure: Each hole through which a pile is to pass is formed by a steel sheath T around which the concrete, such as that forming wall W, is cast. The pile P comprises a point V, which is driven in to the ground K by means of a drop hammer R operated by mechanism above water and a hollow tubular shank I. When the pile has been fully driven a rubber tube housed in a slot 7 in sheath T is inflated and grout passed from gallery F through a tube, not shown. into the small annular space between the pile P and sheath T. Gun propelled rivets may be used to secure sheath T and pile shank I before the grouting is done. Where each pile emerges from the roof of subway S, a diver burns off the projecting part thereof and the piles may subsequently be filled with concrete C as pile Q, a reinforcing cage being lowered into the pile before concreting if desired.

Abstract: 740,860. Retreading tyres. HAMILL PROPRIETARY, Ltd., B. A. Oct. 9, 1953 [Oct. 13, 1952], No. 27887/53. Class 87 (2). A tyre, retreading mould comprises complementary segmented sections 6, 7, 8, the section 8 being fixed to a base support 11 and the sections 6 and 7 being hinged at their lower ends upon horizontal axes 9, 10 so that air cylinders 30 having piston rods 33 attached to lugs 39, 40 on sections 6, 7 open them to the position shown in Fig. 4. The tyre is ejected by the upward movement of bar 63 operated from air cylinders 67 and guided by shaft 61 attached to rectangular plates 73, 74 moving on spaced roller pairs 77 on parallel upright members 71a, 71b and having further rollers 79 located within the space 71d so as to contact laterally the members 71a, 71b. The members 71a, 71b have an upstanding bracket 71f to which is attached a transverse bolt 32 to which projecting lugs 31 of cylinders 30 are pivoted. Each mould section has three annular mould cavities 80 each containing a matrix 81 with removable segmental members 82, fitting the cavity 20a defined by a steam chamber 20, which are retained in place by end flanged member 83. Steam is fed to the chamber 20 via feed pipes 21, 22 connected to swivel couplings 23 so that sections' 6, 7 may be fed via pipes 24, 25, the steam then passing to section 8 via pipes 26b, 26d and swivel coupling 26c. The air is controlled by valve 50, pipe 51 communicating with a source of pressure air which is fed to parts 43, 44 to open the mould segments 6, 7 and to ports 46, 47 to close the segments. In operation, the segments 6, 7 are opened by valve 50 which admits air to the cylinders 30 to open the segments 6, 7. The tyres T to be retreaded are then placed in the mould cavities over the tyre engaging bar 63 and the valve 50 operated to close the mould, bolts 55 retaining the sections in place. Steam is then admitted to vulcanize the retread, the mould opened and the valve 50 further operated to feed air to cylinder 67 which moves shaft 61 and thus bar 63 upwards to disengage the tyre. Hydraulic means may replace the air pressure means, and electrical heating replace the steam heating.
