IMPROVEMENT IN MACHINES FOR COILING SPIRAL SPRINGS.
Specification forming part of Letters Patent N0. 209,254,
August 29, 1877.
f To all whom it may concern:
Be it known that I, GEORGE F. GonLEY, of in the county of Philadelphia useful Improvements in Ma hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l is a plan view of my improvements. Fig. 2 is a transverse vertical section. Fig. 4 is a detail longitudinal vertical section of one of the wheel-clamps. Fig. 3 is a broken plan, showing the tapered end of a bar before coiled into a spiral spring.
The object of my invention is to provide an adjustable clamp for holding spiral springs and the bars from which said springs are made while being coiled on the mandrel.
My invention consists of a clamp composed, essentially, of two guide-wheels, one of which is constructed and arranged so as to permit it to be adjusted to and from the other, so as to regulate the space between said wheels according to the varying thickness of the bar being coiled.
Referring to the accompanying drawings, A A represent two sides of a coiling-machine, and B the mandrel. G represents the carcaused to move in the usual manner parallel with the mandrel by means of a screw-spindle. (Not shown'in the drawing.) is an a r bor on the carriage O, sustaining a short shaft, E, having a head, 6, body 6, enlarged neck 6 and threaded end 6 by means of which it is secured in position by the aid ofa nut, 0 F is a wheel, having a hub or collar, f, which surrounds the enlarged neck 0 of the shaft E, turning freely thereon, and G is a loose wheel turning on said hub f H is a concave shield or plate, resting on the arbor D, and connected to the wheel G by clips h h, whose turned-down ends h enter an annular groove, 9, in the periphery of said wheel. I is a lever, pivoted on a standard, L, secured to the carriage 0, said lever having a pivotal connection at i with the shield H. By turndated October 22,1878; application filed ing the lever on its pivot L the wheel G may may be moved on the hub f to or from the wheel F, so as to diminish or increase the width of the annular channel M between said wheels, to conform to the varying thickness of the bar being coiled.
N represents a shaft parallel to the mandrel B, and sustained on the of a handle, 0. The body of said handle is extended toward the mandrel and affords support to a shaft, P, wheels Q R, and shield S, of the same construction as the shaft E, wheels F and G, and shield dimensions than the last named.
T is a lever, pivoted at t and connected to the shield S at s, to move the wheel It to and from the wheel Q to vary channel U.
The operation is substantially as follows: The end of the bar to be coiled is passed into the space M beneath the shaft E and above thelcarriage 0, when it is fastened to the mandre length wise, the bar is drawn through the space between the wheels F and G and coiled. s soon as the machine starts or the mandrel coil passes While thus progressing the wheel G is kept constantly held up to it, pressing it against the wheel F, and controlling its tendency to turn over on its side or twist, said wheel G being moved by means of the handle or lever I toward the wheel F, so as to diminish or increase the width of the channel M, according to the varying thickness of the bar, it being desirable to have said channel just wide enough to permit the passage of the bar, and
the principal necessity for the adjustment of the wheel G arises from the variation in the thickness of the bar caused by the tapered end of the latter, the bar diminishing in width toward the ends, as shown in Fig. 3. The sectional detail in Fig. 3 of the .bar in cross-section.
