WILLIAM H. FIELD, OF TAUNTON, MASSACHUSETTS.
IMPROVEMENT IN NAIL-PLATE FEEDERS.
Specification forming part of Letters Patent No. 171,005, dated December 14, 1875 application filed November 27, 1875.
To all whom it may concern:
Be it known that I, WILLIAM H. FIELD, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and Improved N ail-Plate Feeder, of which the following is a specification:
This invention consists of feeding-jaws in i which the griper-rod rests, and which are made to close on the rod, and then move forward the breadth of one nail by a rod moved forward by the machine and backward by a spring, and in its backward movement allowing thejaws to open, and moving them backward along'the rod for a new hold to feed again.
Figure 1 is a side elevation of my improved nail-plate feeder. Fig. 2 is a front-end elevation, and Fig. 3 is a section on line as a; of Fig. 1.
Similar letters of reference indicate corresponding parts.
A is a supporting-bar bolted to the machine at B, for supporting the feeding-jaws O D, and the lever F and rod G for working them. The arm of jaw O is provided with a broad bearing-disk, H, in the center of which it is pivoted by the bolt 1, having a tension-spring, J, to the stationary disk K, attached to bar A. v On this pivot the two jaws swing forward and backward to feed the nail-plate. The jaw D has a friction -roller, E, at the lower end, against which the cam-shaped endof lever F is pushed by the rod G when moved outward by the machine, which causes the jaws to gripe the griper-rod and. carry it forward to feed the plate, the forward movement of the jaws being effected by the rod Gr still pushing back after cam-lever F closes the jaws. Bod G. which is moved in the reverse direction by the spring M, first releases the gripe of the jaws on the feeding-rod, by withdrawing lever F from the friction-roller, and then swings the jaws back by pulling the lever against the shoulder of a bracket, N, of feeding-jaw O.
The length of the feed is regulated to the required size of nails by the adjusting-screws O and P in the bar A, and bracket N, which may be set to allow the jaws to swing back more or less, the rod G being free to stop, as required.
Having thus described my invention, I claim as new and desire to secure by Letters Patcut-- 1. The combination of rod G and cam-lever F with jaws O and D, when said rod is arranged to be moved forward by the machine and backward by a spring, and jaw O is pivoted suitably for swinging forward and backward to feed the rod, substantially as specified.
. 2. The combination of bracket N and adjusting-screws O P with lever F and jaw G, substantially as specified.
3. The combination of supporting-bar A, actuating-rod Gr, cam-lever F, and the feedingjaws, the latter being pivoted to the supportin g-bar, substantially in the manner described.
