Title: Improvements in and relating to fastener driving tools
IPC: B25C1/04
Filed: 1970-06-25
Abstract: 1,274,377. Fastener driving tools. SPOTNAILS Inc. 25 June, 1970 [24 Nov., 1969], No. 30928/70. Heading B4C. A pneumatically actuated fastener driving tool comprising a double loaded or spool shaped fastener driving piston 51 reciprocable within cylinder 30, and a buffer 58 for normally limiting the travel of the piston on a drive stroke, includes apertures 57 whereby compressed air may pass into the cylinder between the heads 52, 54 of the piston, and bores 64, 65 whereby air trapped between the heads 52, 54 may escape to atmosphere should seal 56 on the head 54 pass beyond the lower part of the cylinder 30 due to failure of the buffer. In operation actuation of trigger 47 causes space 42 above valve 31 to be exhausted to atmosphere via passage 43 and bores 45a, 44c, 44b. Air in space 40 acting on under surface 31a of the valve causes the valve to move against bias of spring 33 thus closing communication between bore 34a and atmosphere and opening upper end of the cylinder to the space 40. The piston is thus driven on a driving stroke. The piston is stopped by the buffer, and the air between the heads 52, 54 will in this driven position, be at a higher pressure than that of the air acting on the upper surface of the piston due to seal 53 passing the apertures 57. Release of the trigger will cause return of the valve 31 to its illustrated position, and the air between the heads will initiate a piston return stroke. Shoulder 30a compresses the seal 53 so that the piston, when returned, is positively held in its illustrated position. Buffer failure will result in venting of the space between the heads so that the piston will not be returned to its illustrated position. When a buffer has failed housing part 23c can be removed to permit buffer replacement. During movement of the piston the seal 53 engages the wall of the cylinder. In a modified embodiment instead of apertures 57 the piston includes a bore 355b (Fig. 12) which communicates via a one-way valve with the space between the piston heads.

Title: Improvements in or relating to electric relays
IPC: H01F7/08
Filed: 1923-12-17
Abstract: 230,557. Reyrolle & Co., Ltd., A., and Mirrey, J. Dec. 17,1923. Electromagnetic relays.-An overload relay, which resumes the off position when the current falls off slightly, has a magnetic circuit the reluctance of which changes a minimum amount when the armature is attracted, and variations of setting are brought about by varying the air gap between the armature and the magnet poles, the armature being adjustable relatively to a movable member on which it is mounted. The movable member carries the movable contacts of the relay so that, in altering the setting, the operative stroke of the armature is not changed. As shown in Figs. 1 and 2, the armature, which co-operates with the poles A of a horse-shoe magnet, is a light plate of strip iron bent up with wings B<1>, B<2> so as to maintain substantially constant reluctance in all positions. It is pivoted at B<4> to a movable balanced member C pivoted at C<1> and is adjustably attached thereto by the engagement of the spherical head B<6> with an eccentric groove in a disc E mounted on the member C. The disc may be rotated bv means of the knob F to adjust the position of the armature in respect of the poles. The operative movement of the armature is the same for all settings and serves to carry the strip contacts J mounted on the member C, from the normal position shown in Fig. 1 upwards into engagement with fixed spring contacts K with a wiping movement. The relay may be closed by hand through the intermediary of the push rod L<2> the bell-crank L<1> and the plunger L.
