' andthe handle member constitute the principal parts and portions of our wrench in its preferred form of construction.

The outer wrench member or socket lis preferably made cylindrical or slightly ta- "pered toward'its lower end and is preferably provided with a hexagonal recess 1'" extending inwardly from its lower or small end. I The wrench or socket- members 2, 3 and t are of similar construction the latter fitting respectively wit-hinthe former and the'wrench or so'cketinember 2 fitting within the wrench member 'Said wrench members 2, 3 and 4t are preferably made of hexagonal tubes of such sizes that the inner tubes may be readily shifted z'txiallyfivith respect to the adjacent outer'tubes. It will be here noted that the wrench or socket members are adapted to fit hexagonal nuts, bolts, or other members.

It is obvious that the tubes or wrench members of other cross section may be similarly used I and combined to fit nuts, bolts or other mem- The outer or normally lower ends of all of the wrench members are preferably slightly tapered or bers of difieren't shapes.

rounded at said ends so as to permit the wrench members to be inserted into small recesses. l

Spaced from the outer or lower end of the wrench member 1 and extending transversely through the central portion thereof, is a guide and stop member 5 which is secured in position by means of ascre w 6 extending through a flange portion 5? at the one end of the member 5 and int othe member 1, asshown best in Fig. 5. Said member e-extends also through longitudinal slots in'the wrench or socket- members 2, 3 andt, as'shown in'Figs. 5, 6 and 10, permitting said wrench or socket members to be shifted axially with respect to the member l but also prevents said wrench or socket members to be withdrawn from the member 15 The guide and stop member 5 also takes the torsional strains from the adjacent outer wrench member from the'wrench member 0 ,which-theinitial strain is applied. l ""'The upper enlarged end of the wrench member'l is reduced and provided with a reversible ratchet 7 having rectangular longitudinal grooves in itsperiphery. Around the ratchet is rotatably mounted the wrench rotatlng member 8 which is in the form of an annular collar having extended portions 8 at its-diametrically opposite sldes. The rotating member or collar 8 is retained-in position'against theshoulder, formed by the reducedportion of the member 1, by the retaining member 9;, which, together with the retaining member 10, is secured to the upper end of the wrench member 1 by screws 11.

In the extended portions of the collar 8,

are provided slots which extend transversely with the axis of rotation of the collar. In

of the springs 15 engage the opposite ends of e the pawls and normally force said ends out wardly from thecollar. 8, as shown bestin F 1 and 8. The outer ends of said pawls are provided with enlarged portions lQ fand 13 respectively, which portions extend transversely with the pawlsand parallel with their 7 pivotalalxes and are considerably rounded at their outer sides, as shown in Figs. 1, 41,8

and 11. I g I The handle 16 is bifurcated'at its'one end and is'adapted to receive in the bifurcated portion the collar 8.. The ends ofthe furcations are provided with pivot pins or trun nions 17, which extend into diametrically opposite holes 8 in the annular member or collar 8, said holes being positioned intermediate the extended portions of the annular member or collar, as shown in Fig. 8. Thus the handle 16 is pivotally conneeted'to the annular member or.collar 8 so that the former may swing to either side of the latter, or to any intermediate positionrelative to the latter. WVhen the handle is shifted to the position shown in Figs. 1, 2, 6 and 8, thesame is adapted to engage the outer end of one of the pawls'and disengage said pawl from the ratcl1et,as shown in Fig. 8, and when the handle isshiftedto the opposite side of the annular member or collar,

the same is adapted to release the formerly depressed pawl and engage the other pawl,

correspondinglydepressing the sameanddisengag ng the opposite end thereoffrom the ratchet, thus permitting the ratchet to be rotated in either direction bythe ratchetand pawl means when the' handle is shifted to its opposite positions relative to the member *8, as stated. The handle-16 is provided with a cam or rounded portion 16 at the point ofengagement thereof with the outer ends of the pawlsso that the pawls are more readily depressed when engaged by the handle, asshown in Figs. 8 and 11.

The arms orfurcationslti of the handle are 4 preferably made of separate-mem'bersjand secured to the main portions 16 'of'the handle by means of screws 16, so that the pivot pins or trunnions 17 may be readily renewed when necessary. i j I h In the upper orheadend of the wrench or socketv member 1, are rotatably mounted the head ends of a plurality of wrench member adjustingscrews 18, 19 and 20, respectively for adjusting the wrench members 2,3 and 1.

At the upper or inner ends of, the wrench or socket'members 2, 3 and 1, are provided in- Wardlyextending portio is'or sockets 2, 3 and a respectively, into which the adjusting screw-s extend for adjusting said wrench mem- 7 here, said portions 2 '3 and P being also ill.

' adapted to prevent the removal of said wrench members from the mainyor outer wrench member 1; portions 2 3? and 4 are alsov so shaped as to readily slide past each other when adjusting the separate wrench. members inwardly or outwardly. The screwsl8, 19 and20 are provided with large pitch or multiple threads so that the wrench meinbersinay be quickly adjusted inwardly or outwardly.

The retaining member 9 at the upper end ofgthe wrench member-l is provided at upper-side with a transverse groove 9 in which is reciprocallyinountcd the slide2l,

said slide being retained inposition in said groove by the retaining member or plate 10 positioned at the outer side of the member .9.

The retaining member 10 is provided with a transverseslot 10, coincident with the groove 9, through which the outer. end of the slide 21 extends. 1 At the inner portion of the slide 21 is reciprocally mounted a plunger or screw adjusting key 22 which is provided with a reduced stein extending beyond the upper end of the slide and to which is secured a knob 28. Around t-he stem 22 is positioned a com-- pression spring 24: which engages the shoulder at the lower portion ofthe key and is adapted to force the key portion 22 at 'itsinn'er, end into the slots in the heads of the adjusting screws, as shown best in Fig. 5. It will be here by means of the screw20, isshown in its outer oroperative position for rotating a small nut or bolt. In order to adapt the wrench for alarger si'ze nut or bolt, the member 4 screwed inwardly rotating the screw 20 in the properdirection; then the knob 28 is with drawn, disengaging the key 22 from the head of the screw 20. and shifted opposite the head of the screw '19 and released the knob 23 then rotatedin the'properdirection so that the wrench orsocket ineniber'3 is forced out wardly, as shown by dotted lines in Fig. 5 Iii the wrench is to be adapted for the next size. nut or bolt, the wrench member 3 is shifted inwardly and the member 2 forced outwardly.
