WIRE-POlN-TING MACHINE.

SPECIFICATION forming part of Letters Patent No. 279,124, dated June 12, 1883,

Application filed January 4, 1883. (No model.)

' To all whom it may concern Be it known that l, OURTIs B. BRAINARD, a citizen of the United States of America, residing at J oliet, in the county of lVill and State of Illinois, have invented certain new and use ful Improvements in ire-Pointing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a perspective vie Fig. 2, a central vertical sectional view; Fig. 3, a crosssectional view on line 1;, Fig. 2; and Figs. 4 and 5, detached enlarged views of the upper ends of the beaters.

y This device is for the purpose of pointing wire or rods of metal, and is intended to be used in connection with wire-drawing niaehinery, for the purpose of reducing or pointing the end of the wire or rod so it can be started on through drzuv-plates to reduce the wire in size.

The general construction of this device is shown in Fig. 1; and it consists of the shaft K, mounted in suitable boxes, D, at either end, and provided with the fly-wheel \V, and at about its central portion with a fast pulley, E, and loose pulley E, the power being applied to the fast pulley E to drive the machine. On the other end of the shaft K is a wheel or disk, H, firmly keyed to it, so it revolves with said shaft. This wheel or disk H is provided at its periphery with a projecting flange or rim, x, of the form shown in cross-section in Fig. 2, and which stands next to and revolves against the vertical plate B, which is firmly attaehed at its lower end to the frame A of the machine, as is shown in Fig. I.

In Fig. 1 the vertical plate B is shown as broken off at its upper end to show the parts between it and the rotating disk H. The vertical plate B is provided 011 its side next the disk H with an. annular projection, B, being an integral portion of said plate, as shown in Fig. l, and arranged concentrically within the projecting flange of the disk H. This ring or projection B, being smaller in diameter than the projecting flange of the disk H, leaves sufficient space between it and said flange for the. swiveled cams c to operate, in, as shown in Fig. 3. The ring Bis cut across at equal distances its entire depth for the reception of the four beaters a, in which channels they are caused to slide to and from each other toward a connnon center, as shown in said Fig. 3, so that as they approach each other they may, compress any object that is placed between their approaching points and beat it to a pointon accomit of the form of the ends of the beaters (0 shown in Fig. 3. The inner side of the projecting rim of the disk H is provided with the four swiveled cams a, corresponding in number with the beaters a, and at equal distances from each other, and attached to the face of the disk H by the pins 2' for a hinge, and on which they tilt, as shown in Fig. 3. The coilspring s, in a recess in said rim of the disk H, presses on the outer end of said swiveled cam and holds the other end up against the lower end of the set-screw 40. The outer ends of the beaters A are provided with friction-rollers R to roll along on said swiveled cams and cause less friction than if the beaters themselves came in contact with said cams, which are thicker at their rear end than at the other, so that as they pass along over the ends of the heaters when the disk H rotates they will gradually force all the beaters c simultaneously toward a common center to compress anyrod or wire placed in between them in the opening shown at I Fig. 2. The set-screws 10 set the rear ends of the camsc near or farther from the ends of the beaters a, so they may be forced nearer together or farther apart, as may be desired, to point the wire or rod between them much. or little. The springs S serve to draw the beaters aapart from each other after their upper ends are free. The annular plate 911,

Fig. 3, serves to hold the beaters in their respective channels in the ring B, so they may not become displaced.

The wire to be pointed enters the machine in the tapered aperture P within the machine, as shown in Fig. 2, where the pressure of all the beaters (I, brought to bear upon it simultaneously from all sides, reduces it to a point. It is intended that the disk His to run fast, so it will cause the beaters a to act like hammers on the wire to hammer it to a point.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. In a wire-pointing machine, the combination of the shaft K, disk H, having the pro jeeting rim ac, swiveled cams c, set-screws w,

coil-springs S, heaters a, having the frictionrollers R and operating in the channels of the ring B, and face-plate 13, having the tapered aperture 1, all adapted to operate as and for. the purpose set forth.

2. In a Wire-pointing machine, the combination of the heaters a, tapered swiveled cams c, set-screws w, and disk B, as and for the purpose set forth.

8. In a wirepointing machine, the series of radial heaters a, adapted to move simultaneously toward a common center, in the manner and for the purpose substantially as set forth.

4. In a wire-pointing machine, the Vertical plate B, having the integral ring. 13, provided with radial channels, in combination with the heaters a, springs S, disk H, and swiveled cams c, as and for the purpose set forth.

In testimony whereof I affix my signature, in presence of two Witnesses, this 28th day of December, 1882.

CURTIS B. BRAINARD.
