Title: Improvements in or relating to power transmission mechanism and variable speed gearing
IPC: F16D67/00
Filed: 1930-05-02
Abstract: 353,109. Variable speed gearing. MARTIN, P. and DAIMLER CO., Ltd., Daimler Works, Coventry. May 2, 1930, No. 13559. [Class 80 (ii).] Transmission mechanism including an hydraulic coupling C having a primary vane wheel directly driven from the vehicle engine A. and a secondary vane wheel directly connected to epicyclic toothed change speed gearing H, is provided with means controlled by the driver for preventing rotation of the secondary vane wheel and consequently of the toothed gearing when the engine is running, even when the gearing is set in its neutral position. This arrangement overcomes the tendency for the secondary vane wheel to rotate the gear wheels when the engine and primary vane wheel are idling or rotating at a low speed insufficient to drive the vehicle. In the construction shown a brake drum L is mounted on the shaft connecting the secondary vane wheel to the epicyclic gear and brake shoes M are applied thereto by the hand-lever O which operates the ordinary hand brake of the vehicle. Specifications 164,042, [Class 80 (ii), Gearing, Variable-speed &c.], and 353,108 are referred to.

Title: Improvements in electrical variable speed gears
IPC: F16H61/40
Filed: 1951-06-07
Abstract: 695,245. Electric control systems. DELETAILLE, E. June 7, 1951 [July 6, 1950], No. 13580/51. Class 40 (i) [Also in Group XXIV] The preselector element of a continuouslyvariable speed gear positions correspondingly the control element of a follow-up switch, the follower element of which is driven with, and controls the stopping position of the means for adjusting the gear 'ratio. As shown, Fig. 1, an electric motor 3 drives the output shaft 11 through belts 6, 10 and a change speed device 8 of known type in which the output to input speed ratio is varied by translation of a member 12 in-direction A or B according to the sense of the change. The preselector element comprises an arm 40 which is rotated to the desired gear-ratio position as indicated by a pointer 41, and through a cable drive 37, pinion 35.and a rack 34 moves a spindle 33 axially to a corresponding position. A ring 47 rigid with the spindle accordingly moves one or other ot two spring biased collars 43, 44 along the spindle out of engagement with its associated switch contact pair 26-28, 27-29 carried by the member 12. The switch pair so released, close, when, provided the preselector lever 40 has been also rocked in the direction of arrow C to close the gear changing switch 22, a relay 18 is energized, locks, and closes the stator circuit of the three-phase motor 16 over the closed switch pair 26-28 or 27-29. The motor 16 then drives through worm gearing 15, a nut 14, which engages the threaded portion 13' of shaft 13 and thereby moves this shaft axially to follow up the axial movement of the spindle 33, and at the same time effect the gear change. The motor 16 is stopped and relay 18 is released when the member 12 has moved the actuated switch pair into engagement with the associated collar 43, 44 to open the switches. Four switches 26-29 are used, two for each direction of rotation of motor 16 since reversal is effected by reversing the connections to two of the stator phases. In a modification one pair of switches 57-58 only is used Fig. 6 to control two relays 51, 52 to effect change over of the phases of motor 16. The spindle 33, may in this case carry rigid therewith  a sleeve 60 ending in conical portions 61, 62 for actuating the respective switches 57, 58 the normal position being as shown with the switch actuating elements 63, 64 spaced apart a distance equal to the length of the cylindrical portion of the sleeve 63 and engaged thereby to hold the switches open. Further embodiments, are described Figs. 7, 8 (not shown) using a D.C. motor for effecting the gear change with the follow-up switch arrangement of Fig. 1 or Fig. 6.

Title: Rod mill switch
IPC: B21C47/24
Filed: 1964-04-02
Abstract: 992,912. Rolling. MORGAN CONSTRUCTION CO. April .2, 1964 [April 5, 1963], No. 13606/64. Heading B3M. A rod mill switch, for directing successive lengths of rolled stock alternately into one of two discharge channels, comprises a rigid support 26, on which is clamped a block 40 formed with two delivery channels 52 and 54, and an arm pivotally attached to the support to enable a nozzle 142, attached to the upper end of the arm, to be aligned with either of channels 52 or 54. The arm is held by pivots 68 and 78, Fig. 4, in an extension 76 of the support, the pivot 78 being spring loaded to the right to accommodate wear. A support bracket 128, bolted to the top of the arm, is internally threaded to adjustably support the nozzle, and locates a guide tube 12 in an integral ring 132. Clearances between the tube, the nozzle, and the block 40 accommodate expansion of the parts due to heating. For pivoting the arm a transverse rod 112 is attached to the lower end of the lever, a water bucket being attached to each end of the rod. In operation, a rod A from rolls 2 passes from a tube 10 to the guide tube 12, its leading end activating photo electric cells 16, and thence to the nozzle 142, the channel 52, and a delivery tube 53. The rolls 16 cause a valve 124, supplying water to the bucket 116, to open, and a valve 122 to close. Each bucket is provided with holes which drain the water at a desired rate when the supply is cut off. The bucket 116 thus fills while the bucket 114 empties, the nozzle being urged to the left. The nozzle is prevented from moving into alignment with the channel 54 by the rod itself, the rod being pressed against a central guide 58 of the block 40. However, as soon as the end of the rod reaches the channel 52, the nozzle moves to the left into alignment with channel 54. This sequence is repeated for following lengths. The pivotal movement of the nozzle is restricted by its contact with the

Abstract: 735,569. Press button retractive switches. BEER, D. C. Sept. 8, 1952 [June 8, 1951], No. 13642/51. Class 38 (5). A snap-action switch has a leaf spring 51 held in compression between a contact arm 33, fulcrumed at 39, and an operating member 34, the spring fitting into notches 50, 52 in the arm and member respectively. The member 34 is fulcrumed at 43 and when acted upon by a member 57 attached to a push-button 69, moves the spring 51 across dead-centre, moving the contact 49 up with a snap-action against a further contact 44. The comparatively large movement of the end 53 of the member 34 for small push-button movement results in large contact-pressure, so that the switch may be constructed as a micro-switch. The pushbutton is encased in a rubber sheath 73 to exclude moisture. In a modification (Provisional Figure not shown), the operating member is slotted to pivot on a projection on an anchoring plate, and the contact arm pivots about a bent-up portion of the anchoring plate. The contact member has a metal bridging barcontact inserted in it.

Title: Improvements in and connected with liquid bottling machines
IPC: B67C3/06
Filed: 1936-05-14
Abstract: 457,312. Bottling-machines. WORSSAM & SON, Ltd., G. J., and FOX, D. P. S., Wenlock Road, City Road, London. May 14, 1936, No. 13703. [Class 125 (ii)] The invention comprises mainly the automatic filling of bottles with liquid under control of counter-pressure due to counter-head wherein a counter-pressure charge is admitted to the bottle and the bottle is filled with liquid under a constant head of pressure, while permitting the escape of gas, and admitting to the bottle a counterpressure due to an adjustable counterhead for determining the liquid level in the bottle, and finally permitting discharge into the bottle of the liquid column in the filling tube. A further feature of the invention consists in the automatic maintenance of correct counter-head by the control of gas pressure supporting the counter-head. An apparatus for carrying out the invention is shown in Fig. 2, wherein a circular reservoir a is supported on a rotary column a<1>. Filler-heads b are provided with revoluble cocks c. Each cock has a star-wheel t, t<1> for turning the cock step by step. A pipe d extends from each cock into the gas space and admits counter-pressure to the bottle to be filled. A tube e likewise extends from each cock c and permits displaced gas or fob to pass from the bottle to the reservoir. Ports f in the reservoir admit liquid to the cocks which pass the liquid to the fillerheads b. The liquid supply pipe h is fitted with a head h<1> from which a short pipe o<2> depends which has a larger bore than the pipe h. The pipe o<2> opens into a box w suspended from the cover. The pipe h passes through a hole in the box w. Thus the cover a<2> can revolve in a gastight manner around the pipes o<2> and h. The chamber for the gas bell k is formed in the upper part of the column a<1> and the bell k is vertically adjustable in the chamber, the degree of adjustment being indicated. A pipe n communicates with the chamber l and the gas space of the reservoir a. Communication between the pipes S, S' is controlled by a float valve j. The gas supply to the ball k comes via the pipe o and the float valve p, which admits gas to the pipe each time the float rises to normal level. Each time pressure is lowered in the reservoir a, the gas escapes through holes k<1> and bubbles up through the liquid column. In order to accommodate bottles of different heights adapters 17 are provided with tubular extensions 18. The bottles g are elevated by a small circular platform 23 on a rod 24. Airlift pistons may be used for this purpose. The bottles may be fed to the machine by a conveyer. The top of the bell k is connected by a pipe q and each cock c is connected to a manifold q<1>. A trigger device 25 operated by the extension 18 in the adapter 17 operates the star-wheel t<1> and the cock c to initiate a sequence of cock operations. These operations which are described in detail in the Specification give the results set forth above. Specification 284,748, [Class 125 (ii)], is referred to.
