BACKGROUND REFERENCES u.s. Pat: No. 1,343,667; us. Pat. No. 2,752,809.
BACKGROUND OF THE INVENTION It is, of course, a common experience to find that a bolt must be held against turning while a nut is removed therefrom. While there are many examples of bolt locations that make it difficult to secure a wrench to the head of a bolt and another wrench to the nut threaded thereon and to turn one relative to the other, the bolts THE PRESENT INVENTION The general objective of the present invention is to provide a tool to facilitate the removal of front shock absorbers, an objective attained with a tubular member of substantial length having a nut portion at one end and a socket at its other end shaped and dimensioned to fit the nut to be freed. A shaft slidable and rotatable within the tubuler member is connected thereto to limit the extent to which it may slide to two extreme positions. The shaft has a head provided with a channel shaped and dimensioned to fit the rib on the nutreceiving end of the shaft and in oneof said positions the head is within the socket while in the other position the head is within the tubular memberbut remote from the socket. Means are provided to enable the shaft to be held while the nut is turned.
Another objective of the invention is to provide a tool in which the shaft extends through the nut portion of the tubular member with its exposed end provided with a nut portion engageable by a second wrench.
Another objective of the invention is to provide a tool operable with a single wrench, an objective attained by providing the tubular member with a housing portion within which there is an internally toothed ring gear concentric with the shaft which is provided with a circumferential series of gear teeth. Idler gears within the housing are in mesh with the ring gear and said gear teeth which are of sufficient axial extent to maintain said meshing relationship in any axial position of the shaft. Preferably the shaft is spring-biased towards the first position of the head.
Other objectives of the invention, more fully detailed subsequently, relate to preferred means for interconnecting the tubular members and their shafts and to a preferred rib-receiving channel formation.

FIG. 2 is a section on an increase in scale, taken approximately along the indicated line 2-2 of FIG. 1;
FIG. 3 is a section taken approximately Along the indicated line 3-3 of FIG. 2;
FIG. 4 is a side elevation of a tool in accordance with another embodiment of the invention;
FIG. 5 is a section taken approximately along the in dicated line 5-5 of FIG. 4;
FIG. 6 is a section, on an increase in scale, taken lengthwise of the tool; and
FIG. 7 is a section taken approximately along the indicated line 77 of FIG. 6.
THE PREFERRED EMBODIMENT OF THE INVENTION The tool shown in FIGS. 1-3 has a tubular member, generally indicated at 10, andconsisting offirst and second sections 11 and 12 of the same inside diameter. One end of the section 11 has a counterbore 13 of substantial length establishing a shoulder 14 and has an axial bore 16 of the same diameter as the counterbore 13. A nut is welded to the end of the section 1 l. The section 11 has a flange 17 at its other end.
The secondsection 12 has a cylindrical chamber 18 at one end closed by the flange 17- of the first section 11 when secured thereto by screws 19. The other end of the section 11 is in the form of a socket wrench 20 dimensioned to fit the nut 21 threaded on the bolt 22 anchoring, by way'of example, one end of a frontshock absorber, generally indicated at 23, to the frame 24 of an automobile. The bolt 22 is of thetype having a rib 25 extending transversely of its nut-receiving end.
A shaft 26 is slidable and rotatable in the sections 11 and 12 and is provided witha cap 27 atone end that is a slidable and rotatable fit in the counterbore 13 thus to seat on the shoulder 14 and prevent itsescape of the shaft 26 through the socket 20 towards the-shaft which is resiliently urged by a compression spring 28 within the counterbore l3 and heldcentered by the head of the screw 29 securing the cap 27 to the shaft 26 and by a boss 30 on the undersurface of the backing plug 31 held captive by a snap ring 32 caught in an annular channel 33 in the counter-bore 13. The other end of the shaft 26 is formed with a channel 34, preferably inwardly tapered towards the bottom thereof, dimensioned to receive within it the rib 25 on the exposed end of the bolt 22.
The shaft 26 is provided with lengthwise channels that establish a circumferential series of teeth of a gear 35 of an axial extent such that, in any operatable lengthwise position of the shaft 26, the gear 35 will be exposed within the chamber 18 the interior surface of its side wall being formed as an internally toothed ring gear 36 concentric with the shaft 26. A series of three pinion gears 37 are spaced about the shaft 26 in mesh with the ring gear 36 and the gear teeth 35. Desirable and as shown, the teeth of the ring gear 35 extend to the rim of the chamber 18 and the flange 17 is shouldered to provide a boss 38 having splines 39 to receive the upper ends of the teeth of the gear 38.
In use, the mechanic places the tool with the socket 20 fitted on the nut 21. He then fits a wrench 40, usually of a ratchet type, on the nut portion 15 and as he turns it the shaft 26 turns until the channel 24 registers with the rib 25 at which time, the spring 28 forces the channel into holding engagement therewith so that further wrenching is effective to turn the nut 21 free. In practice, the gear train is in the order of 3:1.
The embodiment of the invention illustrated by FIGS. 4 7 requires the use of two wrenches and consists of a tubular member 41 having a nut 42 welded on one end, the nut having a bore 43 of the same diameter as that of the tubular member 41. The other end of the tubular member 41 has a counterbore 44 of substantial axial extent defining a shoulder 45 and opening into a socket 46 shaped and dimensioned for wrenching engagement with a nut 21.
A shaft 47 is slidable and rotatable in the bore of the tubular member 41 and has a head 48 dimensioned to be slidable and rotatable within the counterbore 44 and establishing a shoulder 49 engageable with the shoulder 45 to limit the retraction of the shaft 47 to a predetermined extent. The head 48 has a channel 50 shown as in the form of a socket and like the channel 24, its sides taper inwardly towards the bottom thereof, the channel 50 also dimensioned to fit over the rib 25 on the boltreceiving end of the bolt 22.
The shaft 47 is longer than the tubular member 41 and has a nut portion 51 on its exposed end. A snap ring 52 fixed on the shaft 47 between the nut portions 42 and 51 serves to limit the extent to which the shaft 47 may be advanced relative to the socket 46. In use the mechanic fits the socket 46 on the nut 21 and turns the shaft 47, if necessary, until the channel 50 fits over the rib 25. A first wrench, not shown, is used to hold the nut portion 42 and a second wrench is used to hold the nut portion 51 of the shaft 47 so that the shaft 22 may be securely held by one wrench while the nut 21 is wrenched free with the other.
