DEVICE FOR COILING METAL RODS.

SPECIFICATION forming part of Letters Patent No. 428,971, dated May 27, 1890. Y Application filed December 7, 1889. 'Serial No. 332,927 (No model.) Y

T0 @ZZ whom t may concern:

Be it known that I, FRANK G. TALLMAN, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented new and useful Improvements in Devices for Ooiling Metal Rods; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to'the accompanying drawings, and to the letters of of reference marked thereon, which form a part of this specification.

My invention relates to improvements in devices for coilin g metallic rods as they emerge from the rolls.

The object of my present invention is to provide a device by which metallic rods are thrown into coils as they emerge from the rolls, said coils being arrested by a suitable standard.

In the drawings, Figure 1 is a View in perspective of a set of rolls, guide-tubes, coiling devices, and the standard for catching the coils. Fig. 2 is a sectional view of my improved coiling device. Fig. 3 is a view in perspective of the coiler. Fig. 4 is an edge view. Fig. 5 is a front view. Fig. 6 is a rear view. Fig. '7 1s a sectional view of the guidetube. Fig. is a view in perspective of a modiiication of the coiler. Fig. 9 is a longitudinal sectional View of the device shown in Fig. 8. Fig. lO is an end view of the same.

A indicates the housings, and B the rolls mounted therein, which are of the ordinary construction of rolls for rolling metallic rods.

C is a guide-pipe mounted in suitable supports in front of the finishing-grooves D in the rolls B.

E is a supplemental guide-pipe adj ustably mounted in the standard or support F by means of an inverted-U -shaped bolt and nuts, so that it can be adjusted longitudinally to direct the rods into the coiling device at any suitable angle.

G is the coiling device mounted in a sleeve or bearing H in the upper portion of the support F, said coiling device consisting of a sleeve I, having a grooved pulley-wheel K at its outer end adapted to receive a drivingbelt L, by which the coiling device is driven from any suitable source of power.

The central portion of the pulley-wheel K is provided with a series of openings M, which are separated by the spokes or division-plates terminating in the pyramidal guide O, which projects toward the rolls, and the guide-tubes O and E. i

The pyramidal guide O may be made concave, as shown in Fig. 3, so that there will be no possible chance of theA end of the rod catching and doubling up in the coiler; but the rod will be invariably directed through one or the other of the openings M. The rod in its coiling motion is held against the spokes or division-plates M by the concave surfaces of the pyramidal-shaped guide O; but as soon as the forward motion of the rod ceases by reason of its exit from the rolls B the end of the rod is free to move within the coiler without subjecting the same to a twisting action. The openings M on the outer face of the coiler are provided with bosses P, so as to increase the surface and thus prolong the life of the coiler.

R indicates a standard or catcher for receiving the coils as they are formed by the coiler G. Each standard may be mounted in pairs on a revoluble shaft S, and of the construction described and claimed in my patent, No. 412,565, dated October 8, 1889, and a further description of them being deemed unnecessary in this connection.

I do not wish to be understood as limiting myself to the number of holes M or spokes N used in the coiler, nor to the form or section of the holes or spokes shown, for the reason that a common pulley with a pyramid or other like device for holding the rod out toward the end of the spokes or the sides of the holes will work equally as well.

The supplemental guide-tube E enables the operator to direct the rods and also to adjust the shape of the coil by moving the said pipe to or from the coiling-wheel, so that the angle formed by the rod in going through the coiler will be greater if the outer end of the pipe E is nearer the wheel than it would be if th'e end of the pipe was farther removed from the coiler.

In Figs. 8, 9, and 10 I have shown a modification of the coiling-wheel shown in Figs. 1, 2, 3, 4, 5, and G, and, instead of -using the pyramid al central portion- O, I employ a U-shaped guide B', bolted to the wheel L on IOO the side next the nishing-rolls and of such Y a shape as to insure the delivery of the front end of the rod into a particular opening M in the Wheel. vhen this opening opposite the guide B is Worn out, the tap-screwpB" is unscrewed and the guide B moved around to another opening, and so on until the wheel is Worn out. It will be readily seen that this construction absolutely prevents the front end of the rod from striking anywhere except at the proper point on the cone to direct it into and through the opening in the coilingavheel, and gives me the advantage of the Whole Wheel with the holes M, of such shape that the back end of the rod will not twist up.

That I claim, and desire to secure hy Letters Patent, is-

l. In a device for eoiling metal rods as they emerge from the rolls, a rotating wheel or pulley having openings, and a guide or guides secured to or formed with said wheel placed in the path of the rod as it emerges from the rolls, the sides of said opening in the wheel adapted to engage thc rod and deflect it, thus imparting to the same by the rotation of the Wheel a ceiling or spiral motion, as set forth.

2. In a device for coilingmetal rods, a rotating wheel or pulley to impart a ceiling or spiral movement to the rod as it passes therethrough from the rolls, the spokes of said pulley constructed of substantially oval or of triangular section with the edges of the oval or triangular spokes inclined toward the advancing rod, as set forth.

3. In a device for eoiling metal rods as they emerge 'from the rolls, the eoiler G, provided with a series of openings M, and a pyramidalshaped central portion O, for directing the rod to one of the openings.

4. In a device for ceiling metal rods as they emerge from the rolls, the coiler G, provided with a series of openings M, and a pyramidalshaped portion 0, iu combination with the adjust-able supplemental guide-tube E, as set forth.

5. In a device for ceiling metal rods as the)y emerge from the rolls, the adjustable supple mental guide tube E, placed between the guide-tube C and the coiler G, as set forth.

In testimony whereof I affix my signature in the presence of two subscribing witnesses.

FRANK G. TALLMAN.
