PCT No. PCT/SE83/00170 Sec. 371 Date Dec. 28, 1983 Sec. 102(e) Date Dec. 28, 1983 PCT Filed Apr. 28, 1983 PCT Pub. No. WO83/03790 PCT Pub. Date Nov. 10, 1983.A device for driving fasteners such as nails, screws etc., including a fastener receiver and guide for receiving fasteners in a position for co-action with a fastener-driver and for guiding the fasteners toward the intended fastener-driving location. A fastener magazine having a fastener guide channel for guiding fasteners is arranged in side-by-side relationship toward the fastener receiver and guide and a feeder is provided for feeding fasteners arriving from the magazine to the fastener receiver and guide. The feeder includes a bifurcate member arranged to co-act with the guide channel in the magazine. The bifurcate member has an elongate groove formed by tines or legs of the bifurcate member. For the purpose of feeding fasteners one at a time, the bifurcate member is pivoted forwards and backwards from a fastener-receiving position, in which the groove is directed obliquely towards the magazine, through an intermediate position, in which the groove extends transversely over the whole of the guide channel, to and beyond a position in which the groove extends obliquely toward the fastener receiver and guide and the mouth of the groove extends across at least substantially the whole width of the guide channel. The edge defining the mouth of the groove located nearest the magazine in the fastener-receiving position of the bifurcate member forms an acute angle with the symmetry plane of the guide channel. |
