J. ILER & W. PITZPATRIOK.
Specification of Letters Patent No. 11,053, dated June 13, 1854.
reference being hadfto the annexed drawings, making a part of this specification, in which Figure 1 is aside elevation. Fig. 2 is a top view, and Fig. 3 is an end view of the barrel, showing the end of the nose pieces, cam, saddle, &c.
The same letters refer to like parts in each of the figures.
The nature of our invention consists, first, in the employment of a cam, which is attached to the barrel, and works on a bedplate or bearing, in such a manner that the nose pieces in the reciprocating rotating movement of the nipper barrel, are raised and made to clear the bed knife; secondly, in constructing the nose pieces in such a manner, so as to permit the jaws of the nippers passing between the nose pieces far enough, to feed the scrap end of the nail plate as close up as possible, the nail plate being kept sufliciently tight, and is guided in the jaws or ends of the nose pieces by an arrangement of spring and guide for that purpose.
This nail late feeder is intended for and adapted to the use of any ordinary cut nail machine.
The description and operation of the feeder is as follows, viz: A A is the frame work.
pulley receives a reciprocating motion by means of a connectlng rod'E, connected in pieces and nail the usual manner to some moving part of the nail machine.
F is a cam firmly secured to the barrel.
G is a bearing or rest plate for the cam to slide upon.
H is a saddle guide placed over the barrel, and kept in proper position by means of the spring (g) and arm or support (2).
J J are the nose pieces orjaws, which are made with an opening, so as to permit the jaws and head of the nippers (y) passing through the opening far enough to feed the nail plate as far up to the cutter as possible; the rivet (m) of the nippers striking against the inner edge of the jaws prevents the nippers from slipping'through under the cutter.
(h') is a spring, and (it) is a guide, attached to and passing through slots 2') and the grooves (j j) in the jaws of the nose pieces; this arrangement of guide and spring, is for the purpose of guiding and holding the nail plate i L is a bed, knife upon which the nose plate rest while the cutter is acting.
while still retaining its guiding power over the barrel.
We wish it to be understood that we do not claim the revolving cylinder through which the nail plates are fed as that device is not ne'w,and is to be found in several devices for the purpose, among others it will be found in the patent granted to Caleb Isbister dated the 31st December 1844.
substantially in the manner, and forthe purpose, as herein represented and described.
2. We claim constructing the nose pieces J, J, with an opening between them, so as to permit the jaws of the nippers (3 passing into this opening for the purpose of feeding the scrap end of the nail plate as close up to the cutter as possiblethereby leaving less scrap iron, as described and shown.
