Abstract: 920,452. Vehicle-handling trollies. SIMON-CARVES Ltd. Aug. 23, 1961 [Sept. 28, 1960], No. 14868/60. Class 78 (4). A dolly 52, which may be mounted as shown on a traverser 51 movable between the lift shaft or shafts and storage cells of a mechanical garage and ejectable from such traverser to pick up or set down a vehicle, consists of a platform which may pass beneath a vehicle between its opposite side wheels and which embodies roller-carrying arms which are operated to lift the rear wheels of the vehicle clear of the ground for carriage by the dolly and also to align the front wheels of the vehicle. The rear wheels are lifted by two pairs of pivoted arms 59 which comprise spindles 105 enclosed in rollers 106 and are movable between an initial position in which these arms abut the longitudinal sides of the dolly and a wheel-engaging position as shown. Such movement is effected through the linkages 104, 106, 107 of Fig. 5 under the control of a rod 112 longitudinally reciprocable through the agency of a cable 120, conveniently acted on by a fluid pressure operated piston-cylinder unit 99, Fig. 1. A similarly operated cable-rod-linkage-pivoted arm system 97, 91, 88 and 87, 60 (Fig. 2) effects outward movement of a pair of roller-encased rods 61 which when operated engage the inner side walls of the vehicle's front wheels to align them and steady the vehicle on the dolly. The projection of the dolly 52 from its traverser 51 is effected by means which allow for its displacement to either side of the traverser. In the form shown this means comprises two further fluid pressure members 64, 65 connected to sheaves 69, 70 around which are passed cables connecting the traverser to a subframe 75 which is in turn similarly connected to the dolly 52. In a modification (Fig. 8, not shown), the cables are replaced by endless multiple chains, one of which endless multiple chains is mounted on the dolly and driven by an electric motor. This chain engages to move bodily and also rotate a shaft which drives a second endless chain on the subframe, and a further shaft in the second endless chain system has a pinion engageable with a rack on the traverser. This system may be automatically controlled by an electric switching system (Fig. 14, not shown) making use of limit stops on the dolly, subframe and traverser to govern the extent of movement of the dolly.

Abstract: 593,871. Liquid meters. WILKS, M. F. C., ROVER CO., Ltd., HURST, W. F. F. MARTIN-, and BUSH, E. J. June 18, 1945, No. 15456. [Class 69 (ii)] In a device for metering liquids, e.g. the flow of fuel to a carburetter, a piston 33 completes an electrical circuit at either limit of its stroke to cause operation of a change-over valve mechanism and at one end of its stroke energizes solenoid operated means to transmit impulses to a counting mechanism. Liquid enters a float chamber 1 through a filter and is distributed by a solenoid operated slide valve 3 to opposite ends of a cylinder 2 and is exhausted through a passage 31 to an outlet port. At the end of a stroke, the piston engages contacts 38, 42 to energize a relay coil 46, thereby 'moving a pivoted magnetic armature 49 to close with contact 51 and thus energize the valve operating solenoid 18 to move the valve into a position to reverse the flow of liquid to the opposite cylinder end. The piston returns and at the opposite limit of its travel closes another switch 42 to energize relay coil 47 which moves armature 49 to make contact at 50 and energizes the solenoid 52 which actuates arms 53, 54 for progressing the drums 55 and 56 of a counter. At the same time the solenoid 19 is energized and 18 de-energized, thereby causing the valve to return and the fluid flow is again reversed. A float in chamber 1 carries a needle valve for venting the chamber to atmosphere through a port 14. According to the Provisional Specification, the filter consists of a wash-leather filter arranged around a cylindrical metal shield.

Abstract: 595,225. Charging trucks into mine cages. INTERNATIONAL COMBUSTION, Ltd., and DAVIDSON, G. W. June 19, 1945, No. 15564. [Class 78(iv)] A method of operating winding apparatus in mines wherein the loaded trams are hauled up the pit shaft in two cages which are arranged so that when one cage is at the bottom of the shaft ready for loading, the other which has previously been loaded is at the top of the shaft ready for unloading is characterised in that a loaded tram is discharged from the top cage by an empty tram moved into the cage and, before or after being emptied, is transferred laterally to a position in alignment with the position taken up by the second cage when this reaches the top of the pit shaft, this tram subsequently being pushed into the second cage to displace a loaded tram from this cage and then be lowered to the bottom of the shaft for loading. Figs. 1, 2 show an embodiment in which loaded trams are dis-. charged from double-deck cages 1a, 2a into tipplers 3, 4 and the latter are subsequently rotated to discharge the contents of the tram on to a conveyer. The top deck of cage 1a is first brought into alignment with the tippler 3 and the loaded tram on the top deck is discharged into the tippler 4 by pushing one of two previously emptied trams in the tippler 3 into the cage by a hydraulic ram 5. The lower deck of the cage 1a is then raised into alignment with the tippler 3 and the remaining tram in this tippler pushed into the cage by the ram 5 so as to transfer the loaded tram on the lower deck into the tippler 4. Both tipplers are now moved laterally into alignment with the position occupied by the second cage when at the top of the shaft by rams 3a, 4a and the tippler 4 rotated to empty the trams. When the second cage reaches the top of the shaft its trams are displaced into the tippler 3 by pushing the empty trams in the tippler 4 into the cage by the ram 8. The tippler 3 is then rotated to empty the trams and both tipplers then moved laterally into their.original position and the cycle repeated.
