IMPROVED WIRE-POINTING MACHINE.

Specification forming part of Letters Patent'NO. 48,283, dated June 20, 1865.

To all whom t't may concern:

Beit known that I, C.`JILLSON, ofthe city and county of Worcester, and State ot' Massabeing broken away. Fig. 2 represents alongitudinal vertical section through the same. Fig.

' 3 represents a detached view, hereinafter to be referred to.

To enable others skilled in the art to make and use my invention,I will proceed to describe its construction and operation.

A represents the table or stand which supports the working parts of my machine. The

. hollow Wire shaft B, in which the wire G to be pointed is secured, has its bearings a b supported upon the stands D E, and a hollow arm or frame, K, extends from the box Z) over the length of the table A, and its end is supported by the upright F. t"

Gr represents an adjustable bed-plate, which is hinged at d to the table A, and which can be set at any desired inclination by means of the setscew g, whose end bears on the table A. The bed-plate Gr is provided with ways It, which serve to support the sliding,` bed II, to which the cutter-frame I is secured.

I use in this machine two cutters, one for pointing the wire and the other for cutting off the points. wire is secured to the frame I, and can be adjusted in its position by means ofthe set-screw m, and the cutter 0 for cutting off the points is secured within a sleeve, 1J, of the cutterstand, wherein it can be moved longitudinally by means ofthe thumb-screw q, which passes through the-lugs r and s of the cutter and sleeve,for the purpose of cutting off the points.

The cutter L operates upon the lower side ofthe wire in pointing the same, and it is evident that the taper which it cuts upon the wire must be in proportion to the inclination of the bed-plate G, ou which the bed H and The cutter L for pointing theV cutterstand are moved during the operation of the machine. V

The bed Hand cutter-stand are moved longitudinally during the operation of themachine by means of the lever M, which turns uponits fulcrum N, and to whose arm the connectingrod P is secured, whichis pivoted at n to the bed H of the cutter-stand. The end of the wire to be pointed is supported by the eye t ofthe sliding block Q. The latter is provided with suitable grooves, 2, which iit over the guiding-edges 3 of the con. cave arm K, and an elastic band or spring, u, is secured to the block Q and to the inner side of the arm K, which forces the supporting-eye t constantly against the sideof the cutter L during the opera-tion of the latter.

R represents an adjustable cam-plate, which is secured to the side of the table A. Its position can be adjusted by the fastening-screws w, which pass through slots w in the cam-plate It. A toe, y, secured to the bed H, at the proper time comes in contact with the oblique edge 1 of the cam-plate R, thus causing the cutterstand to assume an inclination' by which the cutter, as it proceeds, cuts a second taper upon the wire, which, in conjunction with the rst taper, results in a double-poiuted`pin,as shown on the drawings, the pin during both operations of pointing being supported by the eye t. When the pin is pointed it is cutoff byforcing the cutter o forward by means of the screw q.

It is evident that with this machine a single or double pointed pin can be made by adjusting the cam-plate It accordingly.

In the operation of the machine the wire C is turned by operating the pulleys Sand the cutter-stanti and cutters are fed forward by means of the lever M.

The hinged platform Gr can be let down level and the cam-plate R arranged so that pieces of wire can be single or double pointed, if preferred, and by having a little curved projection on the middle of the cam-surface the same configurations can be turned upon the wire, i
