This invention has for its object a particuthe upper sides of the sections as shown, the larly simple and eflicient device or tool for flanges are located on the lower side of the. holding pistons or for taking hold of pistons sections. The flanges are preferably conof various sizes so that they can be held in a nected together and as here shown, one of 50 5 vise or other apparatus for the purpose of them as the flange 5 is formed with a laterally working on or repairing the same. extending hinge leaf 7 extending over the The invention consists in the novel features edge of the other flange 6 and between lugs and in the combinations and constructions or leaves 8 on the flange 6, and a hinge pin 9 hereinafter set forth and claimed. extends through the lugs and the leaf, this 0 In describing this invention, reference is hinge pin being preferably a loose fit so as had to the accompanying drawings in which to permit a somewhat.rectilinear movement like characters designate corresponding parts of the sections toward and from each other, in all the views. particularly toward each other when the aws Figure 1 is a plan view of this piston 10 of a vise are clamped toward each other.

I Preferably,.a spring 11 is interposed be- Figure 2 is a transverse sectional View, the tween the flange which tends'to separate the contiguous portion of the aws of a vise being sections 1. 'Also, sufiicient clearance is proshown in sections and the piston being individed at 12 at, the end of the hinge leaf 7 to cated in dotted lines. permit the pivotal or relative movement of This piston holding device comprises body the flanges toward each otherwhen they are sections which are substantially flat and proclamped beween the jaws of the vise.

25 ing projections on the opposite side thereof of jaws 2 and then the piston holder placed for entering between the jaws of a vise, these between the jaws of the vise andthe aws projections being preferably movably fastightened on the flanges 6, 7 thus snugly holdtened together and also preferably, a spring ing the piston so that a workman can work is interposed between them tending to sepon the same. Obviously, the tool may be 30 arate them. made with only one series of jaws 2.
1 designates the body sections which are What I claim is: semi-discoidal lngeneral form. A piston holding device compr sing semi- 2 are the spaced apart jaws, there being discoidal body sections formed with a plu preferably three jaws in each series so that rality of spaced'apart piston engaging aws the piston 3 is engaged at three points. Also, on one side thereof, opposing flanges extendthe sections 1 are provided on the side thereing diametrically of the sections respectively of formed with the jaws with a recess 4 for and located on the opposite sides of the secaccommodating or forming a clearance for tions to those on which the jaws are located, projections that might be on the head of the the flanges being opposed to each other and 4 piston. adapted to be received between, the jaws of a The -semi-discoidalseetions 1 are provided vise.
