The operativeposition of'these socket openings is illustrated in Fig. 53 in which the bolt I and the nut Il are-shownimd'ot and dash lines. A means is provided for' turning the tubular `member in one direction or the other for tightening orloosening .the nut Il l.relative to the bolt l0. This means includes a wheel i! havinga dual set o f ratchet teeth, One set of ratchet ,teeth I!! extend in one 'direction and `the other set of teethfb extend. in the other direction.`

A means is .provided for removably but nonrotatively supporting the wheel I 9 upon the tubular member I1. This means comprises a dovetailed projection |9 formed on the wheel I9 which engages a complementary dove-tailed cutout I1' extended inwards `from the end oi' the tubular member I1. A portion of the metal I1 removed from the tubular member I 1 for formis desired to remove the wheel I9 itis merely necessary to remove the set screw 20 and the piece of metal I1 and slip the wheel oil.' the end of the tubular member` |15.

A handle portion 2| is cooperative with the lwheel I9 for permitting the tubular member I1 to be turned. 'Ihis handle 2| is formed oi' adjacent halves 2 I* which are held together by means v of `a. plurality of screws 22.l The top portion of that part of the handle which engages around the tubular member I'I is provided with a pair of oppositely directed pawls 23 and 24 which are adapted to cooperate with the oppositely directed teeth I9 and I9b of the wheel I9. These pawls 28 and 24 are pivotally supported upon a bolt 25 and are adapted to be selectively engaged with the teeth |9 and I9.

The pawl 2l is cooperative with the teeth I9l for permitting the tubular member I1- to be turned clockwise and the pawl 23 is cooperative with the teeth I9!J lior permitting the tubular member I1 to be turned counter-clockwise. When the pawls 23 and 24 are pivoted to the inoperative position they are adapted to be main tained out of contact with the teeth I9* and I9b by means of pins 28 which extend from Vtheir respective side walls oi' the handle 2|.

A means is provided for holding the rod I2 and the tubular member I1 in various longitudinal adjusted rotative positions with relation to each other for. permitting the square socket opening I8 to be engaged upon the square projection IIIb and the hexagonal socket opening I8 upon the nut II regardless of the relative position oi' the nut I I and the square projection Illb. This means comprises an enlarged portion I2l formed on the rod |2 adjacent the free end of the tubular member I1. This enlargement I2* is formed with a plurality of circular grooves 21 extending completely therearound. A screw 28 is passed through the end of the tubular member I1 and is adapted to engage the grooves 21 for rotatively non-slidably supporting the tubular member l1 upon the rod I2. However, a means is provided for preventing the screw I8 to be moved from one groove 21 to another groove 21 to permit the longitudinal positions oi' the tubular member I1 and the rod I2 to be shifted.

'This means comprises al plurality of connecting passageways 21l extended `between the grooves 21. Springs 29 are extended across the passageways 21* on both sides thereof for retaining the screw 28 in position within its groove 21.

When it is desired to shift the position of the tubular member I1 and the rod I2 it is merely necessary to align the screw 28 with the springs 29 and force the same through the connecting passageways 21n to the desired groove 21 for holding the tubular member against further 1ongi' tudinal movement with relation to the rod I2.

These springs 29 are extremely ilexible for permitting ilexing when the screw is moved from one groove to the other, but are rigid enough to `of the rod |1'in aligned positions with the passageways 29. Likewise, the end of the tubular member I1 is formed with a mark 3| in aligned position with the screw 28 and which is adapted to be selectively aligned with eitherl of the marks 30-for complementarily aligning the screws 28 with either o1' the diametrically opposite passages 21 formed on the rod I2.

'I'he operation of this invention is as follows:

The square socket opening I3 is engaged upon the square projection |91 of the nut of the bolt I0 and the triangular bracket I6 is rested on the ground or other surface for maintaining the rod in a horizontal position. `The mark 8| is aligned with either of the marks 80 for permitting the screw 28 to be shifted into a proper groove 21 for engaging the socket opening I8 of the tubular member I'I upon the nut II. held against rotating by means 'of the rod I8 and the tubular member I1 is rotated by means of the handle 2| for tightening or loosening the nut re1- ative to the bolt I0. To cause the tubular member I1 to be turned in a proper direction, to accomplish either the tightening or loosening, the proper pawl 23 or 24 is engaged with its respective teeth of the Wheel I 9 for properly locking the handle 2| to the tubular member |1.
