J. ILER & W. PITZPATRIOK.

NAIL PLATE FEEDER.

PATENTED JUNE 13, 1854,

JOSEPH ILER AND WILLIAM FITZPATRIGK, OF TROY, NEW YORK,

FAIL-PLATE FEEDER.

Specification of Letters Patent No. 11,053, dated June 13, 1854.

To all whom it may concern:

Be it known that we, JosEPH ILER an WILLIAM FITZPATRIGK, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Machines for Feeding Nail-Plates to Nail-Machines; and we do hereby declare that the following is afull, clear, and exact description of the same,

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.

B is the nipper barrel or guide tube; the upper or back end of the barrel is made with a groove (a) around its circumference, and into said groove is fitted a saddle or bearing (6) upon which the barrel turns; this bearing is provided with journals (0 c) which play in bearings (d d) in the yoke O,

which yoke has motion on a pivot in the socket (6); this arrangement is to permit of any lateral motion of the-other'end of the barrel when necessary; a reciprocating motion is given to the barrel by means of the segment pulley D and communicated to the barrel by means of the belt (f). The

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.

The arrangement of the cam and its bearing, the saddle guide and its spring, is for the purpose of allowing t-he nose pieces or jaws, to clear the bed knife in the reciprocating rotary movements of the barrel and nippers. The cam as it slides upon its bearing or rest plate raises the end of the barrel and with it the jaws or nose pieces and nippers, sufficiently high to clear the surface of the bed knife, the saddle guide by means of the spring which retains it, over the barrel,

yielding to the upward motion of the barrel,

while still retaining its guiding power over the barrel.

The advantages of our invention consist, in the very close manner of Working up the nail plate scrap iron, thereby effecting a saving of time and iron; also in saving from three quarters to an inch of steel on the bed knife, as well as a saving in the wear of the nose pieces, and surface of the bed knife by means of the cam raising the nose pieces high enough in their reciprocating rotary movement, to clear the bed knife; and a farther advantage is gained by removing the spring and guide from the bed knife, and combining them with the nose pieces, as described, so that an unobstructed surface is obtained on the bed knife, thereby removing all liability of the nail plates catching against the guide or spring, and a clip or false nail being made, as is frequently done in the old arrangement of the guide and spring on the bed knife,

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.

Having thus fully described the nature of our invention, what we claim as new and desire to secure by Letters Patent, is:

1. We claim giving a rising and falling motion to the end of the nipper barrel and nose pieces attached thereto, by means of the cam F, bearing G, and guide saddle H, in combination with the nipper barrel B,

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.
