' This Vinvention relates .to improvements in f tools especially designedforholding piston rings, whereby the ringsm'aybe conveniently and accurately iitted' [j l An object of the present invention is lto provide a'v tool for this purposewhich will accommodate ringsv of different "sizes and l'by meansof which the ends ofthe rings may be held in proper relative position for .filing and Athe operation accomplished in a manner to insure proper parallelism for the opposed faces of the ring ends.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described,

Each pair of arms is spaced ,apart to provide ring receiving vgrooves 12 and for this purpose they free'ends of they arms 10 have secured between them spacing blocks 13, -they latter acting to space' the arms apart'and formA end walls yfor the grooves 12. The

blocks are Secured in place by means of p Y 1n reserved to make such changes as proper- 4.ly Vfall within thescopeof the appended in the slotsv 12 adjacent the block 16vis a the drawings whereslidable gripping jaw"which` comprises a substa'ntialy l-l-shapedl head 17.

claims.

Having describedv they invention Vwhat isv claimed is The invention is susceptible `of various f V1. A tool of the class described including Y a plurality of pairs of divergent arms of slidable member located in one. end of thev slots to engage and force the ringsinto .con-

tact With the opposite end Walls of the slots andcompress ther rings and means whereby theslidable -member may be operated.

Y k2. A, tool of ,the class described including a plnralifty of pairs of divergent arms ot' substantially Vshaped formation and arranged in spaced relation to provide spaced slots adapted to receive piston rings, spacf ingy blocks between the ends of the arms, a pin connecting the opposite ends of the arms, a slidable member located in vone end of the slots to .engage and force the rings into Contact with the opposite end Walls of shaped .head adapted ,to engage and force the rings into contact withfthe opposite end Walls .of the slots and'compress the rings,

a slotted arm extending from the head, YaV

guide pin carried .by the divergent arms and extending through the slotted arm and an eccentric mounted upon the guide pin for engagement with the "head whereby the slidable member may be operated.
