Filed: 1942-04-27
Abstract: 556,972. Sliding-clasp fasteners. LIGHTNING FASTENERS, Ltd. (Talon, Inc.). April 27, 1942, No. 5591. [Class 44] In a slider of a sliding-clasp fastener having locking means engaging automatically between adjacent fastener members to retain the slider against accidental movement the usual pulltab is omitted and the looking device is released by a plate-member 18 housed in a recess in the upper wing 6 of the slider and normally flush with the surface thereof. As shown the locking member housed in recess 8 comprises a spring plate 13 having at one end a prong 12 permanently secured in the slider body, and at the other end depending prongs 15 normally extending through apertures in the bottom of recess 8 into engagement between fastener members 2. The central portion of plate 13 has an upwardly bent loop 14. The plate 18 housed in a recess and flush with the upper surface of the slider has depending lugs 19, 20, the inwardly turned lower ends of which are snapped into engagement with the loop 14 to retain the plate 18 and provide operating connection between it and the locking device. To release the locking device plate 18 may be given a sliding movement in either direction longitudinally of the slider (which movement may be limited by ribs, not shown, on the under surface of the plate) this movement lifting the prongs 15 out of engagement by the cam action of lugs 19, 20 on the under surface of loop 14. Alternatively plate 18 may be tilted by lifting either end, or may be raised bodily by finger and thumb engagement with both ends, to disengage the prongs 15. To facilitate manipulation of the plate by the finger-tip or nail the body of the slider may have undercut recesses 22 and the lower face of the slider may be rounded or bevelled as at 23 to facilitate passage of the slider over any underlying object.

Title: Improvements in and relating to devices for transmitting indications of a measuring apparatus to a distance
IPC: G08C19/06
Filed: 1956-02-27
Abstract: 786,140. Counting-apparatus. COMPAGNIE CONTINENTALE D'APPAREILS DE MESURE. Feb. 27, 1956 [March 4, 1955], No. 6057/56. Class 106 (1). A device for transmitting the indications of a measuring apparatus to a remote point comprises means for storing energy supplied by the measuring apparatus, means actuated by the measuring apparatus for releasing the stored energy periodically and means including a magnet and an armature winding actuated by the released energy thereby to generate a voltage which is transmitted to a remote receiver incorporating counting mechanism. A meter (not shown) drives through gearing 4, Fig. 1, a shaft 5 which is connected to a shaft 7 by a spiral spring 6. The shaft 7 carries a permanent magnet 9 which is located between the polepieces of an armature 11 having a winding 12 connected by lines 3 to the electromagnet 13 of a remote receiver 2. A detent 8 normally locks the shaft 7 against rotation so that as the shaft 5 rotates the spring 6 is tensioned until an arm 10 releases the detent 8 whereupon the shaft 7 is suddenly rotated and a voltage pulse is induced in the winding 12. This pulse is transmitted via the lines 3 to the electromagnet 13 which attracts its armature 14 and through a pawl and ratchet 17, 16 actuates a counter 18. In a modification, Fig. 3, the shaft 5 carries an arm 20 which engages a crankarm 21 on the shaft 7 and slowly rotates said shaft until the crank-arm 21 reaches the position (b) whereupon the armature 9 is magnetically attracted to a stable position along the axis A-A. The sudden movement of the shaft 7 may be effected by a helical spring attached to the crank-arm, Fig. 2 (not shown). In another example, Fig. 4, the meter drives through a free-wheel mechanism a disc 30 connected by a crank-pin 29 and a connecting rod 28 to a rod 26 slidable in guides 27. The rod 26 carries a permanent magnet 23 which moves between the polepieces of an armature 24 having a winding 25. A spring 32 is periodically tensioned and released to move the disc 30 ahead of its driving means so that the permanent magnet 23 induces a voltage pulse in the winding 25.
