Title: Improvements in fastenings
IPC: F16B5/10
Filed: 1934-05-23
Abstract: 419,926. Fastenings. CHOBERT, J. F. G., 3, Avenue President Faure, St. Etienne, Loire, France. May 23, 1934, No. 15428. Convention date, May 29, 1933. [Class 44.] A fastening for securing two overlapping elements by pressing the overlapping surfaces of said elements into contact with one another comprises a spring-stressed stem extending through at least one of the elements and having, at the free end of the stem, a manually operable device displaceable relatively to the stem so as to release a yieldingly controlled locking device which normally locks the stem against rotation. The device shown in Fig. 5 comprises a spring-urged stem having a wing handle 21 which is inserted through a slot in the plate member 28 that is to be fastened to the plate member 23. The stem is then rotated 90 by the wing so that the wing lies across the slot and the wing is then turned down to lie flat. A ridged plate 24 slidingly fitted on the stem by a square aperture inserts its ridge into the slot of the plate member 28 to lock the stem against inadvertent movement. When the wing is raised, cam lugs 27 thereon cause the bottom edge of the wing to move away from the ridged plate 24 so that during the rotating of the wing through 90 to the open position the plate 28, no longer being pressed down rises to allow the ridged plate to move out of the slot and so to permit the rotation. Fig. 10 shows a fastening of the cupboard-turn type wherein a double-ended bolt arm 42 acted on by a spring 45 on the stem brings into firm contact the plates 32, 44 which are to be fastened. The wing handle 21 when raised from the flat position causes, by its cam lugs 27, the stem 33 to rise slightly and so allows a spring-urged locking disc 34, Fig. 12, to remove its locking lug 37 from a notch in the housing 30 whereby the stem, which passes through the square aperture 35 of the disc, is released for rotational movement ; such rotational movement is limited to 90 by reason of the longer lug 36 on the disc 34 being constrained to move in a slot in the housing 30. Fig. 24 shows the stem locked by a spring-urged locking bar 69 which is mounted to slide in the stem and has lugs to engage notches in the housing 30. The stem is rotated by a screwdriver or a coin which on insertion in the groove 65 on the head of the stem depresses the bar out of locking engagement with the housing 30. Figs. 32 and 34 show an arrangement in which a milled-head push-button 87 slidable on the head of the stem is projected out of the housing 30 to permit finger rotation of the stem and on depression into the housing a hook lug 90 on the button can be locked in a forked aperture so maintaining the button within the housing and preventing rotation of the stem. By disposing the stem so as to pass centrally through a slot in the member to be fixed and then rotating the stem 90 the two ends of the bolt arm 42 may press on such member.

Abstract: 297,008. Hailwood, E. A. June 10, 1927. Miners' safety lamps. - In combustion-tube fittings as described in Specifications 18694/13, 104,326 and 196,647, a spring arranged above the bracket B carrying the inner glass G is provided to press the bracket upwardly into engagement with the glass to retain the glass in position, depression of the bracket against the spring allowing release of the glass. In Figs. 1 and 2 an extension B<1> from the bracket B, in the form of a strip or tube (comprising an apertured shield B<8> and a centralizing tubular or semi-tubular part E<10>) passes up through the chimney C and carries a ring H<1> encircling the chimney and forming the upper abutment of a spring S bearing at its lower end on a ring F mounted on the chimney. The glass G is thus gripped between the bracket B and the seating ring R at the base of the chimney. In a modification, the ring R, which carries the bracket B in a manner allowing up and down movement, can be adjusted on the chimney and fixed by a set screw. In two other modifications, of which Fig. 7 shows one, the upper spring abutment encircles the chimney near its base and downward releasing movement is restricted to a particular angular position (or positions) of the bracket by means such as a vertical slot B<6> and corresponding projection B<7>. Positioning serrations B<5> may be provided, this construction, as also that of Fig. 6, providing ready means for angular adjustment of the bracket to position the opening in it with respect to the wick tube. A similar effect is obtained with the modification of Fig. 1 by a positioning spring on the bracket or on the chimney.
