Abstract: 1,228,830. Fastener driving tool. VERPA DRAADINDUSTRIE N.V. 20 Aug., 1968 [26 Sept., 1967], No. 39699/68. Heading B4C. A fastener driving tool having a driving member, and a fastener magazine includes a guideway which receives a fastener to be driven into a workpiece. One side of the guideway is defined by a flat portion of a resilient member. When a fastener, e.g. a staple, becomes jammed in the guideway a further actuation of the driving member will pivot the resilient member about an "effective" axis at or above the top of the guideway. As illustrated in Figs. 1 and 3, the driving member 5 is driven by spring 3 after the member has been moved upwardly, by a pawl 19 engaging with a cam 6. A rubber cushion 7 is provided. The resilient member comprises a plate 14 secured in position by a screw 17 and having lugs 16 engaging recesses 18 in extensions 12 of the magazine. Other forms of resilient members are described and illustrated, e.g. the resilient members may be of inverted U-shape with one leg of the U cooperating with the magazine to form the guideway (Figs. 5 and 9, not shown).

As shown there are a plurality of such sets of discs arranged along the track device, the sets of discs being interconnected for rotation together to maintain the slots in suitable relative positions for transfer of a bar or tube from a slot or slots in one set of discs to a slot or slots in another set of discs. The tubes are fed into the slots 6, 6 1  on the first set of discs by the action of a hopper 10. The latter includes two feed rollers 10a, 10b. Shafts 2 of adjacent sets of discs are connected by chain gearing 7, 8 and are driven by an electric motor. The resultant rotation of the discs in addition to providing the drive for the apparatus, causes rotating of the tubes in the hopper by the action of friction of the tubes acting on one another and by the leading tube being in contact with the first set of discs. The track 9 may be curved (Fig. 4, not shown). Rotating wire brushes (not shown) are arranged at each end of the tubes and the bristles of the brushes move over the ends of each tube in a downward direction.

The bases of the cells may be fluid-permeable or provided with capillary ducts, and may form a continuous layer 25 of porous material. Air under pressure may be applied to the interior of a plate cylinder to prevent ink from leaking inwardly and to assist movement of ink. A cylinder of opaque, electrically-insulating material with evenly-distributed gravure cells in it, running in an ink bath, may have porous layers of a photo-conductive material such as tin oxide, of electrically conductive material and of transparent glass or plastics material underlying the cells. Light from a central source is used to cast an image from a negative on the photoconductive layer and induce electrophoretic migration of pigment particles in the ink in the cells, so as to produce an image. Again, the pigment particles may themselves be photoconductive and the image may be produced pboto-electrophoretically.
