The lower end of the cavity 6 is preferably provided Wit-li e eiosure or bushing 9 which may be screwed into the end of the body Q to close the cavity and whose inner end forms en abutment l0 against which re-acts the spiral spring ll, the other end of which aliuts against 'the mide; side of the out 'i'. l; will oe apparent 'wiih the constructie@ jusi described that the gemis, for bending. stioifflieniiig, u

elle 'cool provi-led il t) threads being avoided. The spindle is provided with a head 12 to enable it to be Irotated and above the same with a heavy removable cap 13 provided with relatively yielding material 14, as liber, for contact with the end ol' the spindle, the purpose of this cap being to prevent the end of the spindle from being upset. The other end of the spindle is provided with a removable terminal 15 which may take any one ot' several lerirs and is preferably provided with relatizely yielding material as fiber, as indicated at 1G, in contact with the end of the spindle.

At each side of the spindle S. and body 2 ai'e mounted rods 17 which are freely movable endwise through blocks 18 and whosel effective length is adjusted and maintained by the nuts 19, 20 located respeetirely above and below the said blocks. These rods whose function is ordinarily to exert a pull are provided with removable terminals 21 which may be of any of the forms shown or of other desired character. 1t will be understood that in the use of the tool the terminal 15 on the spindle 8 presses against one part of the work as, for instance, the end of a shaft and that the terminals 21 are in contact with other parts of the work as, for instance, the under side of the wheel or gear to be removed from the shaft. The turning of the spindle would thus result in the removal ot' the wheel or gear from the shaft and if the parts were a very tight lit, they might be jarred loose by striking the cap on the end of the spindle, the spring 11 permittingr the spindle to more with its nut. Where the work might otherwisefbe marred, the terminalsnniy be providedwith comparatively soft material as liberin the manner indicated at 2Q, Fig. 1.

1t is obviously important that the rods 1T should be readil' adjustable and I have ar- `anged them so that they may take up any position within the total range of adjustment and that they may do this automatically to accommodate work of different sizes and in accordance with the straip on the rods. the' rods thus linding their best position without the necessity of manual adjustment b v the user ot' the. tool. The construction which makes this possible is illustra ted clearly in Figs. 3 and l. the blocks 1S acting as there shown as trunnions extendii g across the slots 3 of the cross-head and having` in their ends cavities 23 in which are located spiral springs Qt, the outer ends of which are in contact with opposite faces 25 within the cross-head between the ledges 4 and t. rThis arrangement wauses sufficient friction on said faces so as to hold the trunnion blocks yieldingly in place at any point in thc slot 3 and the trunnions permit each rod to turn around the axis of its trunnion. Furthermore, sutlicicnt play is permitted between the ends of the trunnions and the faces l5 and'betwcen the springs 2l and the cavities 2B in the ends of the trunnions so that the ods may also turn in an v other plane, the result being an eifeetive universal jointe, 1n the construction shown. the movenient of the rods is limited by the width of the slots but is quite sullicient for the purpose intended. The fact that the rods i7 may be adjusted without turningr by merely nninipulating the nuts 19, 2O makes quick adjustment possible and the arrangement of the trunnion blocks and related parts insures the correct location of the rods automatically in accordance with the requirements of the work in any given case.

In `Fig. 5 the tool takes the form of a inachine having the bed plate 2G supported hy the rods or legs 27 which may be secured to the floor by feet 28. -The rods 1T are screwed into the bed plate 26 when the tool is used in this way, the terminals 21 having been removed for the purpose. The tool :ia'y then be used as an arbor press.

r1`hree different forms of terminals 21 for the rods 17 are illustrated, the forni shown in Fig. 1 being as already stated. provided with the strip of fiber QL to protect the work,

the form shown in Fig. 6 being in the nature of the double elav' 21 to retain the chain 29 in place as, for instance, when tubing or rods are to be bent or straightened and the form shown in Fig. 7 which takes the shape of a foot 21b provided with concentric corrugations for co-action with the work.

1n 'order to permit the insertion and removal ofthe blocks 18 and their springs 24; an opening is made at the inner ends of the upper ledges l adjacent the body Q so that the slots 3 are T-shaped at the top. the head of the T being wide enough for the purpose suggested. It may also be noted that the bottoms of the cavities 2B are inclined orbeveled to facilitate movement between the blocks and the springs. the ellect being` on the order of a ball and socket joint. The bottoms of thesaid cavities may be curved.
