Filed: 1919-07-25
Abstract: 141,586. Litchfield, T., Litchfield, W. E., and Vale, E. J. July 25, 1919. Projectors.-In a toy repeating pistol, a pea or similar shot is prevented, from falling out of the barrel by being held between the propelling spring and a lever that retains and releases the spring. A magazine b arranged above the barrel communicates at its front end with the barrel so that a pea falls from the magazine into the space c between the front end of the spring r and a lug h on a lever i and is prevented from falling out of the barrel. The spring r is secured to the trigger m so that when the trigger is pulled, the spring is compressed. Continued movement of the trigger raises the end t of the lever i thus lowering the lug h and permitting the projection of the pea.

Title: Improvements in or relating to vehicle link spring suspension means for curve compensation
IPC: E21F7/00
Filed: 1936-07-06
Abstract: 464,376. Vehicle spring-suspensions. KOLBE, J. July 6, 1936, Nos. 18722 and 18723. Convention dates, July 25, 1935 and April 22, 1936. [Class 108 (ii)] In vehicles in which the body is connected to the chassis by inclined links provided with springs in order to compensate for lateral forces, in the vehicle unloaded condition the springs on both sides are given an initial tension of sufficient magnitude to counteract the action of forces up to a predetermined magnitude which tend to displace the body from its normal position. As shown in Fig. 1, the links 3 are provided at 2 with rubber springs adapted to act under torsion. The spring comprises a number of rubber discs 6, the interior edges of which are rigidly connected to a hexagonal rod 7 non-rotatably carried by the axle 1 and the exterior edges are connected.to the link 3. A central disc 9 is also connected to the rod 7 through a sleeve 10 of length shown and peripherally to a ring 11 having a lug or stop 12. Upon the sleeve 10 are arranged stop members 13 having projections 14 and the disc 9 may be given a twist to impart initial tension which is maintained by means of the coacting members 12, 14 as shown in Fig. 8. The link 3 is pinned to a sleeve 15 having a recess 17 so that on motion in one direction the initial torsion has to be overcome, while in the other direction it is free to move except against the forces due to the other spring discs to which initial tension has not been imparted. Fig. 10 shows a modification in which a coiled spring is employed either at one end or both ends of the links 37. In normal position the ends of the links 37 engage by means of hooks 29 bearing members 27 on rods 22 which are connected to the ends of a coiled spring 21. The rods 22 are further provided with conical nuts 23 bearing against rubber bearings 24 held in the axle boxes 20. Initial tension is given to the spring 21 by the conical nuts 23 and before movement of the links can take place the initial tension of the spring 21 has to be overcome, but as shown the return movement of either of the links is free. When the spring 32 is employed it is put under initial compression, but in other respects acts in the same way as the spring 21.

[Class 89 (i)] Two-part lock-nuts of the type in which an inner part screws on the bolt and an outer part screws on the inner to effect locking, have both parts elastically deformable. The nut proper, 1, Fig. 1, has a conical extension 4 slotted at 6 and screw-threaded at 3. A groove 8 is formed at the junction of the extension and nut body, one wall of which is conical. The locking member 2 is tapped at 10 and coned at 12 to close in the part 4 and has a conical extension 9 slotted at 11, to enter the groove 8 and be closed in by it on the threads 3, thus giving a double lock. In a modification, the conical bore 12, Fig. 3, becomes parallel at 15 and the extension 9 is replaced by a counterbore 14 slotted at 16, the groove 8 being replaced by a conical shoulder 13.

Abstract: 1300498 Elevation overspeed brake CLARK EQUIPMENT CO 3 June 1971 [15 June 1970] 18733/71 Headings B8B and B8L An overspeed brake mechanism on a stacker vehicle elevator car 10 movable within frames 12, 14, comprises a generator 18 for providing a speed reference signal of the car, brakes 24, 26 on the car for interacting with the frames and brake actuating means triggered when the speed reference signal exceeds a particular value. Each brake comprises a pair of shoes 32, 34 spring biased apart for engagement with flanges on the frame 14, but normally held inoperative against this spring bias by a keeper 46 having pins 50, 52 engaged in holes in the shoes. The keeper pins are subjected to a bias out of engagement with the shoes by a tension spring 64 acting on a bar 48 of the keeper 46, the bar 48 being normally prevented from moving by a half shaft 86 engaging a notch 88 in the bar. The shaft 86 is movable clear of the notch 88 to permit brake actuation upon a fork 96 being retracted by the armature 94 of a solenoid 92 energizable by the generator signal. Movement of the bar 48 for the brake 24 causes movement of a similar bar 72 of the brake 26, through a sprocket 60 and racks 58 formed on the two bars. The generator 18 is mounted on the car 10 and has a toothed rotor 20 drivable by engagement with a rack 22 formed on the frame 14, to generate a D.C. voltage having a polarity according to the direction of movement of the car. The circuit including the generator and solenoid 92 comprises a unidirectionally conductive device and is arranged to operate the solenoid only during downward movement of the car, when the car exceeds a pre-determined speed.

A tubular member 14 screws into a central boss 7e on the lower plate 7 and carries a lock nut 18 adapted to be screwed up the tube 14 to press the lower end plate 16 of the cartridge 5 and through it the cartridge 5 against a packing ring 6f in the recess 6e of the plate 6. The softening medium is held between filter screens 21 backed by perforated discs 20 secured to the cartridge 5. Water to be softened enters through a cock A, flows up the tube 14 and lifts a flap valve 22 to contact the softening medium, purified water leaving past a ball valve 12 in a hollow boss 6g on the plate 6. A carrying handle 31 is provided in the cartridge 5. In a modification, the framing 6, 8, 7, Fig. 3, is tubular and provides an outlet passage and each end of the cartridge 5 comprises an annulus 25 secured thereto and a plug member 24 screwed into the annulus.
