i TATES PATENT OFFICE AUSTIN D. HOFFMAN, OF CHIC/AGO, ILLINOIS, ASSIGNOR TO JOHN E. WHITTLESEY AND JOURGEN W. O. PETERS, OF SAME PLACE.
IMPROVEMENT IN `WIRE-COILING MACHINES.
Specilication forming part of Letters Patent No. 190,139, dated May l, 1877; application filed` March 22, 1877.
To alt Iwhom 'it may concern:
Be it known that I, AUSTIN D. HOFFMAN, ot' Chicago, in the county of Cook and State ot' Illinois, have invented a new and useful Iml'iroveinent in Wire Coiiing Machines, which is i'ully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is a top or plan viewV ot' that part of' the machine which contains my invention. Fig. 2 is a detached View of' the revolving spindle, and Fig. 3, a detached view ol" the` tubular case C.
The nature of my invention consists in a roller and revolving spindle in a spiral-wirc machine, so arranged that the roller forces the wire coiled on the small portion ot the spindle onto the large part of it, as hereinafter described.
In the accompanying drawings, A represents abcd-plate, attached to any ordinary frame or bench. B is a spindle,upon which the wire D is wound to produce the spiral coils.
The spindle B has a shoulder, E, where the smaller part F joins the larger-part G. v
H is a revolving head that has bearings I,
Y `and is revolved by the band-pulley, J.
The spindle B is secured to this revolving head H by means of the set-screw K.
L is a roller, mounted on a shaft or spindle, which revolves in a bearing, M.
C is a tube that passes over the large part G of the spindle B. The inside of this tube 4 is provided with spiral grooves N. The tube G is so arranged on the spindle B that it will not revolve with it.
The operation of my machine is as follows: The Wire is wound on the smaller part F of the spindle B, from a spool placed at any convenient place to deliver the wire to the spindle. As the spindle B turns to coil the wire upon the smaller portion F of the spindle, the roller L striking against the coil passes it from the smaller portion F of the spindle over the shoulder E, upon the larger portion G of the spindle. This roller constantly feeds the coil from the smaller portion to the larger portion of the spindle; and the grooves in the tube C force it along and deliver the wire in a uniform spiral coil from the end of the spindle.
My machine is especially adapted to coiliug two or more Wires together.
The roller L raises the two wires together over the shoulder E, and passes them along in the same spiral coil, without their being separated. p Having thus fully described the construction and operation ofmy invention, what I cla-im, and desire to secure by LettersPatent, 1s-
The spindle B, provided with a shoulder, E, in combination with a roller, L, for feeding the coil from asmaller to a larger circumference, substantially as speciled and shown.
AUSTIN D. HOFFMAN.
