Patent GB-259096-A (GB)
Title: Improvements relating to electrical means for controlling lifts and the like
IPC: B66B1/44
Filed: 1926-02-09
Abstract: 259,096. Etablissements Vernes, Guinet. Sigros, et Cie. Dec. 3, 1925, [Convention date]. Electric plant. - In order to stop a lift A accurately at a landing C, the point at which the feed. circuit of the hoisting motor B is broken is varied automatically in accordance with the load in the lift by means of a wattmeter relay D of known type having a movable member 7 whose argular displacement is strictly proportional to the energy absorbed by the motor B, and hence to the load. When the cam b on the lift opens the contacts a, the relay 15 is de-energized and opens the contacts 13, 14 and 17, 18. The opening of the latter contacts cuts out the coil 2 of the relay D and the member 7 returns to its initial position, the time taken to return depending on the displacement and hence on the load. When the member 7 reaches its initial position, an arm 9 carried thereon opens the contact 10 and the relay 21 is cut out, thereby opening the contacts 19, 20 and cutting out the relay 12 which opens the contacts 23, 24 and cuts off the supply of current to the motor. A disc 8 on the member 7 and a permanent magnet 11 control the speed of return of the member. The relay D includes a coil 5 adjusted for effecting the usual balance of the half load by a rheostat 6.

Filed: 1947-02-08
Abstract: 621,235. Scoop arm machines. FAURE, A., and FAURE, A. Feb. 8, 1947, No.- 3788. Convention date, Jan. 28, 1946. [Class 68 .(i)] In a scoop bucket excavator the bueket G, which is not provided with a door, may be pivotally -connected to the bucket arm B by either of connections 12 or 13 on the back of the bucket, depending whether it is required to be used as a drag or face shovel. The rope 20 controls the movement of the bucket about the connection to the bucket arm B, and ropes 18 and 19 control the boom A and the bucket arm B respectively. A locking device 11 is provided on the arm B for securing the bucket G thereto during digging and consists of a peripherally-flanged disc 25 mounted on a rotatable shaft 23 carried between cheeks on the arm. The peripheral flange has portions 26 cut away, and in a horizontal rib 33 on the back of the bucket an opening 34 is formed, corresponding in section to the uncut peripheral flange 27 of the disc so that, when the bucket is in its digging position, by rotating the disc the bucket is locked to the arm A. Rotation of the disc is caused through ratchet wheels 28 mounted on the shaft 23 being turned by pawls 40 carried on a casing 28, which overcomes and moves against the action of a spring 37 when tension is continued on the rope 20 after the bucket has come against a stop. To release the bucket, tension is again applied to the rope 20, causing further rotation of the wheel to a position in which the rib 33 may move out through a space 26 in the flange.

Title: Improvements in or relating to electric switches
IPC: H01H15/02
Filed: 1920-02-12
Abstract: 164,799. Waterhouse, E. Feb. 12, 1920. Switches, quick-action; contacts; covers and lids.-In electric switches of the enclosed or ironclad type in which the movable contact members are carried by a rod sliding at rightangles through a hinged lid or cover, the rod is adapted inwardly of the lid to operate a transverse bar capable of relative motion axially of this rod against the resistance of a quick-break spring, the transverse bar co-operating with guides provided on the internal surface of the switch casing. The rod a slides through the cover b of the switch case, and carries a loose sleeve h to which is secured a transverse metal bar c, a spring f being interposed between the transverse bar and a washer g. Around the bar c, insulating-material d is wrapped, contact knives c being clamped to the bar c by means of U-shaped clamps e<2> secured over the insulating wrapping, flanges e' of the clips e<2> being riveted to the switch blades c. Alternatively, suitably recessed and flanged parts of the switch blades may serve also as portions of the clamping members. The ends of the bar c are slotted to co-operate with guide-ribs k on the inner sides of the switch casing, preventing rotation of the transverse bar and preventing opening of the cover with the switch in the closed position. A bent spring member j, secured to the inner side of the cover b, serves to grip the bar c or an attachment thereto retaining the switch in the open position, the reaction between the spring j and the bar c or its attachment giving the switch a quick action in its closing operation. In the closed position of the switch, the blades e form a connection between pains of fixed contacts l, and in a modified form the contact bars e may be replaced by fuses, the contacts of which are secured to, but insulated from members which may form parallel sides of an H-shaped metal casting, the cross-piece of which forms the transverse bar c.
