Abstract: 28,868. Smith, E. J. Dec. 11, 1909, [Convention date]. Attaching spiked plates etc.; stapling.- A machine for attaching hooks and eyes, of the type described in Specification 507/06, [Class 43, Fastenings, Dress], comprises a base-plate C and standard D, Fig. 1, having a guide E for the upper plunger F, which is depressed by a cam I on a handle H pivoted at G, the cam acting against a lever J pivoted at K at the rear of the machine. The plunger F, which is held raised by a spring L abutting against a screw M passing through slots N, N in the plunger, carries the upper die O, the lower die being secured to the base-plate. The die O, Figs. 7 and 8, has a flaring mouthed slot Q for the bill d of the hook, Fig. 9, a stop R for positioning it, and working edges Q<1>, Q<2> forming a slot for the body of the hook. The lower die P, Fig. 6, has two inclined guiding faces S, T and a central groove U. The faces S, T bend the prongs into the groove U, the edges Q', Q<2> bending them sharply and forcing their ends out of the groove to lie flat against the body of the hook. To attach an eye, Fig. 10, the upper die O<2>, Fig. 12, has a groove for the body of the eye and two stops R<2>, while the lower die P<2> is provided with two oppositely-inclined faces S<2>, T<2>, Fig. 14. The hooks straddle and are fed down a slide X, Fig. 5, having two guide-plates Y held sufficiently apart by plates A<1>, B<1> to receive the bills, the lowest hook being held by a spring catch G<1>. The end of the slide tapers, and is turned horizontally, having fixed to it an arm D' which extends along the lower side of a guide-block E<1> provided with a groove F<1>. The lowest hook is .fed to the die O by an arm I' pivoted to a bell-crank K<1> a spring M<1> surrounding the pivot holding the arm I' in a raised position. Two lugs N<1> engage the lowest hook, and a lug O<1> engages the second hook on the slide X, so that one hook is fed to the die 0 and the second moved from under the catch G' to position in the guide-block E'. The arm I' is moved forward on actuating the handle H by a slotted link R<1> connecting the lever J and bell-crank K', and is returned by a spring S<1>. While the plunger F is being depressed, the arm I' is kept in position under the die O by a spring-pressed catch T' engaging with a tooth on the end of the bell-crank K<1>, and is released just before the prongs are clinched by engaging with an adjustable screw B' when depressed to a proper position. The arm I' is prevented from rising on its return till it engages the next two hooks by a pin W<1> on the standard contacting with its upper surface, a slot in the arm finally allowing the pin W<1> to be disengaged. In feeding eyes to the setting-mechanism, one guide-plate Y is omitted. and two spring catches are placed at the bottom of the slide X, one for holding back the eyes and the other to press on the eyes as they are fed forward to the dies. The guide-block is substantially flat on its under surface; and the feeder arm is slightly modified to engage the eye better.
