The member 24 is also provided 110 with a plurality of slots 26 registering through the two partsk of the member 21d-,and through these slots and through nuts 25 disposed WithinV the member 24: pins 27 are threaded. These pins Q7 carry pivoted 4heads 28 similar to the heads 1S on the pins 17 and adapted to be likewise adjusted by the application of a Wrench or like implement to the squared ends 29. This adjustment is arranged so that the pins 27 may be set to correspond to the several leaves of the spring, as indicated more particularly Vat Figs. l and E2.

shown at .Figure l, and the spring in its original or straight condition placed upon its edge Vbetween the heads .18 and 2S the member 24% with its associated parts may be f moved by the actuation of the device to the position shown at Fig. 2 whereby the spring is formed to the required curvature.' lt will be understood, of course, that the spring will be in heated 'condition when being so formed and will vremain in the acquired form until cooled and `Will .then be further processed by tempering or lthe like as occasion may make necessary.

From the foregoing description of the de-V vice, it is believed that the operation Will be clearly understood and further description Will be unnecessary. p Y

Whatvve claim to be neivis: l A spring-forming device comprisingv base, frames mounted upon said base, means to move the ramestotvard and from each other in continued parallelism, means canV red by the frames for setting to adjustment to provide curvature of-aninterposed spring, and a plurality of shims mounted Vadjacent the frameV "corresponding in thickness to half the standard variations in widths of springs adapted to be .insertedand superposed selectively beneath the Vframe to raise` the frame adjustably to accommodate springs of diilerent standard Widths.
