MACHINE FOR DRAWING WIRE.
SPECEEIGATION forming part of Letters Patent No. 321,478, dated July 7, 1885.
Application filed May 8, 1894.
To @ZZ whom t may concern,.-
Beit known that I, ALEXANDER R. BEN- TON, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Forming Metal Wire; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a top View of my improved machine for spirally grooving wire. Fig. 2 is a longitudinalverticalsection of the same. Fig. 3 is a detail view showing the recessed casting and the anti-friction balls. Figs. 4 and 5 are similar views showing slight modications in the manner of securing the anti-friction balls, and Fig. 6 is a view of thc grooved wire.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to machines for spirally grooving wires; and it consists in the improved construction and combination of part-s ofthe machine shown and described in the patent to Gorham Gray, No. 276,391, granted on the 24th day of April, 1883, as hereinafter more fully described and claimed.
In the above-mentioned machine there has been a drawback that in grooving very thin wire the friction of the shoulder of the die against the end of the bearing has been so great as to break the wire in passing through the die and turning it, and there has also been a drawback in the shape of the wire not having any guide for its passage between the cutting-rollers, the spirals having not been cut evenly or correctly; and for the purpose oi' overcoming these difficulties I construct the machine as follows:
In the accompanying drawings, the letter A indicates the bearing in which the die B, having the revolving cutters C, rotates, the general construction oi' which parts, as well as of the remaining parts of the machine, have been described in the above-mentioned patent, and need no further description. The forward end (No model.)
of the bearing has an annular recess, D, in the bottom of which a. flat ring, E, of steel is placed, and inside which recess a number of larger balls,F, of steel or other hard material, are placed, having a number of smaller balls, G, placed between them, the large balls projecting slightly out of the recess. A dat ring, H, of steel or similar hard metal, is placed between the shoulder of the die and the end of the bearing, bearing against the exposed portions of the balls; and it will be seen that the said balls, bearing against the hard rings, will offer very little friction, allowing the rotating die to turn without obstruction. In place ol' the smaller balls, segmental strips or blocks I may be interposed between the pio jecting or larger balls, the balls and the blocks revolving freel y in the recess in the same manner as the larger and smaller balls, which construction is shown in et, and, if desired, the recess may be dispensed with and a number of recesses, J, as shown in Fig. 5, may be made in the end of the bearing, in which recesses the anti-friction balls may be placed, the shoulder of the die and the dat ring revolving against the balls; or a ring may turn upon the reduced portion of the die between the end of the bearing and the dat ring, and have a number of perforations similar to the recesses in the end oi' the bearing, in which perforations the balls may be placed, this construction appearing similar to the aforemen tioncd construction when seen from the forward end of the bearing. An upright, K, having a longitudinal perforation, L, in its upper end, is secured to the bed-plate of the machine, and the said perforation registers with and is concentric with the bore in the die, and with the space between the revolving cutters, and a guide sleeve or tube, M, having a perforation or bore of a diameter slightly in excess of the diameter of the wire to be grooved, is secured in the perforation of the upright by a set-screw, N, or similar means, a guide-tube having a bore of a certain diameter being used for each diiierent thickness of wire to be spiraled. It will thus be seen that the die will revolve without any friction or with very slight friction, preventing the wire from breaking, and enabling the IOO machine to be used for any thickness of wire, and that the wire will be fed perfectly true centrally to the space between the cutters, causing the spirals to be cut perfectly regular, the wire passing perfectly straight to the cutters, being guided by the guidc-tnbe in the upright.
Having thus described my invention, I claim and desire to secure by Letters Iatent of the United States- 1. In a machine for spirally grooving wire of the described construction, the combination of the bearing recessed in its forward end, the anti-friction balls placed in the said recess or recesses, the dat ring bearing against the exposed portions of the balls, and the shouldered die, as and for the purpose shown and set forth.
2. In a machine for spirally grooving Wire of the described construction, the combination of the bearing having an annular recess in its forward end, a flat ring placedin the bottoni of the said recess, anti-friction balls of a diameter greater than the depth 0f the recess, anti-friction balls of a diameter smaller than the dept-h of the recess placed in the intervals between the larger balls, the rotary die having the shoulder, and the fiat ring placed between the shoulder of the die and the forward end of the bearing, as and for the purpose shown and set forth.
In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
