Title: Improvements relating to friction-grip fastenings for ropes, wires and the like
Inventor: CLEVERLY EDWIN GEORGE
IPC: F16G11/04
Filed: 1949-12-19
Abstract: 703,350. Cable stoppers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 18, 1950 [Dec. 19, 1949], No. 32538/49. Class 78 (2) A cable stopper comprises a wedge 11 slidable in a sheath 12, 13 and around which the cable 22 is passed so as to be gripped between the wedge and the inclined gripping portions 14, 15 of the sheath and is characterised in that a holding member 17 extends through a.hole 16 formed to receive it in the wedge 11 and through two holes 20, 21 formed in the faces or cheeks of the sheath, at least two of the three holes being elongated in the direction in which the wedge is slidable, and the holding member 17 being slidable through the holes throughout the travel of the wedge between its gripping and retracted positions. The stopper device, Fig. 3, is secured to a fixture by links 50 and secures the rope 22 in the gripping-right-hand position of the wedge 11, the wedge for rope-threading purposes being held in the left-hand retracted position by the engagement of heads 18 or 19 of holding member 17 in the respective hole 20 or 21 of a cheek 12 or 13. The rope, after being threaded therethrough, is lightly held by knurled nut 29 and the holding member 17 is then pressed by the thumb to release the wedge which slides into gripping position when the rope is pulled. Heads 18 and 19 are relatively offset so that head 19 does not fall into hole 21 to jam the wedge. Two devices (Fig. 1) like Fig. 3 are incorporated into the same stopper ; each wedge 11 having an additional peg 31 sliding in slot 32 to give orientation, and the rope surfaces being grooved.

Title: Improvements in or relating to object-manipulating apparatus
IPC: B25J18/06
Filed: 1963-08-19
Abstract: 1,048,288. Article handling devices. AMERICAN MACHINE & FOUNDRY CO. Aug. 19, 1963 [Sept. 7, 1962], No. 32654/63. Heading B8H. [Also in Division H2] An article manipulating device comprises load engaging means, such as a suction gripper head 318, mounted on the outer end of a coil spring 261 which passes between fixed guide rollers 262 and is secured at its inner end in a bore in a vertically movable carriage 20. A pair of cables 278 extend between a collar 270 rotatably mounted on the spring 261, and anchorages 282 slidable on rods 284 carried by a drum 54 which is rotatably mounted in a housing 1. The carriage 20 is raised and lowered by a ball nut which is secured to the carriage and which engages a screw shaft 10 rotatable, through gears 6, 8, by an electric motor. The outer surface of the drum 54 is provided at different level with stops 178 each adapted to engage one of a series of stops 176 when projected by a corresponding projection 146 adjustably secured to a rotatable shaft 114. In operation, the motor is actuated to rotate the shaft 10 to bring the carriage 20 to its lowermost position. As the carriage is lowered, a pin secured thereto and engaging in a slot 80 in a shaft 66 rotates the shaft and thereby, through gears 82, 94, 112 and a ratchet and pawl 130, 124, rotates the shaft 114 causing a prepositioned projection 146 to engage one of the stops 176 to stop counter clockwise rotation of the drum 54 when the spring 261 is in a desired sector of operation. The motor is then reversed to raise the carriage 20 and this rotation of the shaft 10 rotates, through gears 22, 30 and a unidirectional clutch, a shaft 32 and thereby rotates the drum 54 through gears 46, 52, until the appropriate stop 178 engages the corresponding stop 176. Continued upward movement of the carriage 20 raises the spring 261 and the cables 278 raise the anchorages 282 on the rods 284 until they engage stops 295, which are adjustable on screw shafts 300 in the housing 1, corresponding to the selected, sector of operation of the spring 261. The carriage 20 continues to move upwardly until a stop 196, adjustably mounted on one of a series of screw shafts 188 rotatably mounted in slots 186 in the drum 54 engages a cam which is carried by the carriage 20 and which is slidable on a square-suction rod 212. Engagement between the cam and the stop 196 causes rotation of the rod 212 thereby actuating switches at the lower end of the rod to stop the motor as a stop on the carriage 20 engages the stop 196, thereby bringing the gripper 318 to the required position. The cycle is then repeated to bring the gripper to a predetermined position in the next selected sector of operation. Switching means, Fig. 17 (not shown), are also provided for operating the gripper and for establishing time delays during the cycle of automatic operation (see Division H2).

Abstract: 334,118. Eichhorn, E., and Thieme, R. Oct. 29, 1929. Wheels, facilitating detachment of.-In detachable wheel mountings for cycles, of the type wherein the rear wheel is separable from the sprocket ring and connected thereto by coupling elements which allow the wheel to be detached after the axial removal of a supporting axle from the free-wheel hub, the coupling elements are carried by the ball bearing ring to which the sprocket ring is secured and by the inner bearing cone of the hub. The cone o of the free-wheel hub a is normally clutched at r to a ring c carrying the chain wheel b, the ring c being mounted by a ball bearing d on a ring e rigid with a sleeve f, which is secured in the slot of the fork limb h by means of nuts i, k. An axle v passes through the sleeve f and through a sleeve l within the hub a, its threaded end v' screwing into a sleeve s, which is flanged at u and is secured in the fork limb h' by a nut t acting as the mounting step. A flange g on the sleeve f serves to position the adjacent parts. In order to detach the wheel, the back-pedalling brake anchor lever n is loosened, the axle v is unscrewed from the sleeve s by means of a lever or spanner w, and the clutch r between the cone o and the chain wheel ring c is disengaged by slightly spreading apart the fork limbs, thus leaving the hub free for removal.

Abstract: 849,566. Winch control gear. ELBA-WERK, ETTLINGER BAUMASCHINEN - UND HEBEZEUGFABRIK G.m.b.H. Oct. 23, 1957 [April 26, 1957], No. 33011/57. Class 78 (5). A hand-propelled scraper-shovel (or trench digging appliance) is of the type wherein the shovel is pulled by pull cable 11 towards the winch 100 and the cable is then released so that the shovel may be retracted manually by means of handle 50, the pull cable 11 carrying internally the electric control cable 10 and the operator controlling the electromagnetic clutch 1 by push-button 16 positioned on the said handle. The improvement lies in an additional control cable 21 whereby the push-button 16 may control clutch 1 when cable 10 is broken. The normal clutch circuit includes clutch 1, direct source 5, switch 7, slip ring 9, cable 10, socket 9, switch 11 and socket 14, the return being by earth. If this circuit is broken, the operator moves over switch 7, so that connection is made by cable 21 to press-button 16, which restores the operator's control over the clutch.

Abstract: 795,783. Resilient mountings. WELLS & CO., Ltd., A., and UNITED-CARR FASTENER CORPORATION. Oct. 9, 1956 [Nov. 22, 1955], No. 33399/55. Class 108(3) An anti-vibration mounting comprises a colunnar member 24 extending through an opening in a base member 12, and two sets of closely coiled helical springs 38, 40, each extending between the member 12 and a respective spring retainer 32 which is free to rotate on, but is restricted against axial movement relative to, the member 24, the springs 38, 40, being under no longitudinal tension, and having their points of attachment to the spring retainers 32 offset circumferentially, and to a uniform extent, in relation to their points of attachment to the member 12 when the mounting is unloaded. In operation, on receiving a downward load upon the member 24, the springs 38, 40, are deformed into the position shown in Fig. 8. This is accompanied by rotation of the retainers 32, the consequential frictional resistance providing a measure of damping. Further damping is provided by frictional engagement between adjacent springs, and by the provision of a damping cage consisting of discs 46, 48, and a spring 50. In a modified construction of damping cage (Fig. 15, not shown), the discs 46, 48, are replaced by respective cups, and the spring 50 acts on the cups through the intermediary of abutment washers or further cups. The peripheries of the cups may be radially slotted. Deflection is limited by the provision of radially extending pairs of resilient stop members 28, 30, the latter being the more resilient. In a modification (Figs. 13 to 16, not shown) the more resilient stop underlies the more rigid stop 26. Specifications 571,026 and 740,519 are referred to.
