Title: Improvements in or relating to fastening devices
IPC: F16B5/02
Filed: 1958-08-06
Abstract: 855.652. Screw fastenings: nuts and bolts &c. ZAHODIAKIN, V. F. Aug. 6, 1958 [June 2 1938], No. 25243/58. Classes 44 and 89(1). A fastening-device includes a hollow receptacle 26 adapted to receive a threaded stud 24 so that the receptacle and stud have a common axis when operatively assembled, there being in the receptacle movable-opposedjaws 35 which are with concave-faces directed towards the central-axis, the faces presenting screw-threads for co-operation with screwthreads on the stud, the jaws and the receptacle having corresponding inclined segmental cylindrical-surfaces of equal radius to one another, in full surface-to-surface contact. As shown, the device is used to clamp together two panels 20, 21. The receptacle 26 is predominantly circular in plan view but with chordal lands 29 which form opposed inclined part-cylindrical channels 32 between the lands, for the jaws 35. The outer surfaces 37, 38, of the jaws engage channels 32 and the lands 29 respectively, while the confronting faces of the jaws are also part-cylindrical and parallel to the major-axis of the receptacle. Also, the jaws 35 are biased by a spring 46 towards one-another and towards the open-end of the receptacle, the degree of movement being limited by a guide-cylinder 43 slidable in a cap 47 enclosing the receptacle 26 and the spring 46. In plan-view, the threads and the jaws are crescent-shaped, the maximum-depth of the threads being equal to the depths of the studthreads. The threads of the jaws and of the studs are so shaped as to provide a ratcheting- action between them when the stud is moved axially-inwardly between the jaws, prior to a final rotary-movement of the stud which locks the stud and the jaws within the receptacle. The stud is releasable by rotary-movement in the reverse-direction, but is held captive on the panel 21 by a split-ring 56 which is engageable with grooves 55 and a terminal-washer 54 on the stud. In another arrangement, (Fig. 10, not shown), a modified form of cap is used and the jaws have interengaging-portions on their marginal-edges, which obviates the need for the guide-cylinder described above. In an alternative arrangement, (Figs. 11 and 12, not shown), the marginal-edges of the jaws are slotted to receive flat-keys.

A packing gland for a plunger 1 in a cylinder 2 of, for example, a liquid spring, comprises a resilient packing ring 13 supported by a metal backing plate 12, a backing ring 21 of porous metal disposed between the packing ring and the backing plate and in engagement with the plunger, and a source 6 of lubricant which communicates with the backing ring 21 whereby lubricant enters the pores thereof and lubricates the engaging surfaces of the plunger and backing ring. The packing ring 13, which may be of natural or synthetic rubber preferably having a filling of fibrous material, is compressed between the plate 12 and a pressure plate 11 from which pegs 15 project through the ring 13 and enter bores 17 in the plate 12.

Filed: 1919-10-16
Abstract: 157,546. Mendel, S. Oct. 16, 1919. Safety-pins; retaining- devices. - Relates to fastenings, additional to the securing pin, to guard against loss of brooches, safety-pins, and the like, and consists (1) in means for slidably attaching and securing the additional fastening to the brooch pin, and (2) in a link or the like connected to the bar of the brooch and linked to the additional fastening to retain the brooch even if the brooch pin becomes detached at both ends. As shown in Fig. 3, a spring loop 3 is secured at one end by a wire coil 4 to the brooch pin 2 either 'by friction or by soldering, and is hooked on to the outer end of the pin after the latter has been passed through the material 6. The loop 3 is connected to the brooch bar 1 by the link 7, or by a chain, to guard against loss of the brooch if it becomes wholly detached from the pin 2, as shown. Instead of a wire loop, a chain 10, Fig. 2, comprising a spiral spring 11 and a ring 12, may be secured to the pin 2 and passed through the link 7. After the pin has been passed through the material, the spring 11 is stretched and the ring 12 passed over the outer end of the pin. In modifications, the loop 3 is hinged or connected to a tubular member frictionally or otherwise held on the pin 2; or the loop, or chain, is retained on the pin by a bent friction plate 20, Fig. 10, or is connected to lugs or the like on the friction plate.

Abstract: 857,479. Electric indicating systems. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION]. Aug. 12, 1958 [Sept. 10, 1957], No. 25897/58. Class 40 (1). [Also in Group XL (c)] In a system for producing a control or warning effect when an alternating error signal exceeds a prescribed amplitude, the error signal is applied to the input of a transistor which is biased so that the transistor conducts to produce the control or warning effect only when the instantaneous amplitude of the signal exceeds the prescribed value. In Fig. 2, 101 and 102 are rotor windings of two compass systems, having stator windings 110 and 112, whose outputs are combined in a transformer 62 to produce a resultant error signal proportional to the angular difference between rotors 110, 112 without ambiguity at 180 degrees. This signal is amplified by transistor 30 and applied to a transistor 40 biased by resistors 19 and 10 so that it conducts only when the A.C. error signal exceeds the bias value. The output current of this transistor renders a further transistor conducting so as to cause a winding 87 to saturate its core and so permit A.C. from a source 97 to flow through tuned windings 88 and 89 to operate a warning lamp 108.
