Abstract: 19,247. Allison, C. A., [Williams Wire Hinging Machine Co.]. Sept. 7. Stapling.-Relates to improvements on the invention described in Specification No. 6064, A.D. 1903. Staples are inserted, so as to interlock and serve as hinges, into boards constituting the parts of boxes and the like, or other boards which require to be hinged. The two parts to be hinged are placed on a table or anvil 2 having a base-part 2<c> which moves vertically in a block 11 adapted to be moved laterally in a block 12 moving vertically in guides 1. The block 12 has a roller 14 against which a cam 15 on a shaft 16 abuts to raise the table. The shaft 16 is provided with a spring clutch, which gears with a loose driving-pinion 18 when a spring cam 24, by which the clutch is normally pushed out of gear, is drawn out of the way by a treadle 26. The table or anvil has suitable stops 3, 4 which are held in position by suitable adjusting-blocks 5, 6. Above the table is a shaft 35 which is rocked by connection, as shown in Fig. 1, with the shaft 16. On the front end of the shaft 35 are arms 40<a>, 40<b>, by which the stapling-mechanism, carried on heads 1<d>, 1<e> is operated. The staples are fed from a casing or hopper 43, or by hand, to tracks 41, 42, down which they fall by gravity, the track 41 conveying staples which are inserted into one part in a vertical position, and the track 42 conveying staples which are inserted into the other part in a horizontal position so as to interlock with the vertical staples. The tracks consist of vertical plates having side ribs on which the staples straddle. The track 41 leads to a vertical guideway 45 in alignment with a guideway 45<a> in a carrier 47 by which the front staple is brought to position for insertion by a driver moving in the guideways. The front staple before it drops into the guideways is held by a spring pivoted lever, which is depressed by the driver. The driver, which is adjustably connected with a sliding-block 49, is actuated by the arm 40<a>. The block 49 on its descent actuates a star-wheel 63, Fig. 26, by which the carrier is brought to position. The anvil clenches the vertical staple, as shown in Fig. 2<a>. A pivoted spring lever 55 is actuated by the driver to feed the staples along the track. The foremost staple in the track 42 is carried from its vertical position into a horizontal position by an oscillating plate 77 having a spring sliding finger which, when the plate is turned into the position shown in Fig. 10, engages with the staple and carries it into the horizontal position along suitable guides when the plate is turned downwards. The plate is suitably fitted with guides to direct the staple, which is driven along the groove 71 in the carrier 72 by the driver 66<a> on the slide 64, actuated by the arm 40<b>. The driver is adapted to push back the carrying-finger of the plate 77, thus releasing it from the staple. The slide 64 is provided with a pivoted dog and guideways for oscillating the plate 77 through suitable mechanism. It also actuates a device 74, Fig. 26, which actuates the wheel 63 to bring the carrier 72 into position. The horizontal staple is clenched, as shown in Fig. 2<b>, by means of the cheek A<2> of an adjustable, angular top plate against which the parts are pressed by lifting the anvil 2 before inserting the staples. The vertical and horizontal staples are thus inserted alternately.
