WILLIAM HENRY WARD, on AUBURN, NEW YORK.
IMPROVEMENT IN THE MANUFACTURE OF COIL-SPRINGS.
Specification forming part of Letters Patent No. 136,473, dated March 4, 1873.
- ends coiled in the same direction, so that the ends terminating at the same end of the coil will perfectly balance each other throughout the coil, and thus obtain in a single coil acompact torsion-spring in which one coil will not overlap or be within the other, but each will be equal and each fold made in the same direction; by which construction the two ends are not only balanced throughout the length of the spring, but the springs may be made of rights and lefts, which is a great advantage for certain purposes, and which could not be obtained by springs coiled in opposite directions.
In the accompanying drawing, Figure 1 represents a view in perspective of my improved balanced torsion-spring; Fig. 2 represents an end view of the same, showing the diameter bar; and Fig. 3 represents a side elevation thereof, showing its coils separated, when adapted as a yielding support.
The spring is made of asingle wire, a, bent first in the middle of its length so as to form a cross-bar, 6, equal in length to the diameter of the coil, and having its ends coiled in the same direction, so as to terminate at the opposite end of the coil in arresters' c d to receive and resist the action of the torsion force. When used as such, the thing to be operated is connected to the cross-bar b, and the ends 7 means for attaching it to the thing which is to be supported.
Having described my im'ention, I claim The coil-spring a b c d, having its coils a b and its ends 0 01 so arranged as to perfectly balance each other and allow of formation into right-and-left springs, as described.
