Spaced vertically above these projeeting members are similar iiai'row projecting members c, vertically adjustable upon t4 depending extremities ot' the opposed series of fingers by means of slotted stems n and studs c?.

These extremities grip orpinch the upper margins of the spring platesI and pattern and exert a pressure thereon eorrespending to that of the lower projections t," upon the lower margins ot' the spring and pattern.

Each upper projecting member upon the stationary series of fingers is provided with an extended shoulder e whieh extends over thel pattern t) and rests upon the upper edge of the spring plate N. thus preventing the plate from wai-'ping in the direelion ot its plane. y

The spring is thus einbrared upon sides and upper edge, b rigid linger members and forced into elose engagement with the depending grating at its lower edge. and in this position while piiiehed into liiial shape by the pressure bet\veen"the stationary and movable series ot lingers, tht-'tempering tank is elevated until the platform and tingers inelosing the spring plate and pattern are immersed in the tempering luid, which 'sets the spring until it' will retain its litted shape al`tei2it is released t'rom the lingers.

.1. ln a machine, for fitting' vehicle springs, a traine. a series of stationary shaping fingers and a series of movable lingers opposed thereto, a depressed platform upon which the spring rests, depressed engaging extremities for the lower margins of said spring` and upon theextremities 0l said series ot' fingers, engaging means for the upper margins ot said spring, said upper engaging extremities vertically adjustable upon said fingers, and a tank of' tempering lluid in which said finger extremities, depressed platform aiid sprint,r are iiniiiersible. and means for reciprocating the movable series ol lingers and for elevating said tank.

ln a maehine tor fitting vehicle spring plates. a traine or bed plate, a series ot shaping lingers. stationary thereon, an opposed series ot' tingers movable upon the bed plate to and from the first mentioned lingers. depressed extremities for the series ot' lingers. a depressed support for the spring plate engaging means for theI lower margins ot said spring attaelied to the depressed extremities ot' said opposed series of lingers. engaging means for the upper margins of said spring. and vertieall)v adjustable. upon said depressed extremities, and extended niei'nbeTs upon some otE the stationary fingers tor engaging` the upper edge otl said spring.
