Abstract
This invention is a unique mechanical combination devised to effect the rapid and efficient removal and replacement of the upper nut on the stem of the front shock-absorbers used in motor-vehicles. A round member, having a squared top, is scored in two places on the circumference thereof, which scores are adapted to receive and hold two snap-rings. The bottom part of the round member is relatively larger in exterior diameter than the body thereof and is interiorly oblongularly hollowed to fit over and to hold the stem of the shock-absorber. The round member with one snap-ring attached is adapted to be placed inside of and to move up and down in, a hollow cylindrical member for a distance governed by the position of the other snap-ring. The hollow cylindrical member has an exteriorly hexagonal hollow top section, the interior diameter of which is fractionally larger than the exterior diameter of the body of the round member and which holds the round member in movable working positions. The squared end of the round member, in place in the cylindrical member, is adapted to be held by a T-shaped handle, with an interiorly squared tail, by set-screw means in the tail of the handle. The cylindrical member has another section directly under the hexagonal top section, which is relatively larger in diameter than the top section. The bottom section of the cylindrical member is relatively smaller in exterior diameter than the diameter of the body of the cylindrical member and the bottom section is interiorly ridged to form an interior hexagon, designed to receive and hold the upper nut of a front shock-absorber.

Description
This invention is a unique mechanical combination which is entirely novel and is devised as a new means for the removal and replacement of the upper nut on the stem of the front shock-absorbers used in all conventional motor-vehicles.
It has been the experience of mechanics and service station and garage operators engaged in the repair and maintenance of motor-vehicles, that it normally takes from 10 to 30 minutes to remove or install the upper nut on the stem of the front shock-absorbers used in motor-vehicles, as these shock-absorbers are generally located and installed in a relatively inaccessible section of the motor-vehicle, which results in difficulty in the removal and installation of same and which, in turn, results in loss of time and in increased labour costs.
My invention makes it possible to remove or install the upper nut on said front shock-absorbers in less than 60 seconds.
It is thus an improvement over the presently known art, in that it is a time and labour saving device of great service in the motor-vehicle industry and is thus of genuine public interest and is a benefit to the economy generally.
My invention is simpler to produce and less costly to manufacture, than the means presently used to achieve the same purposes.
In the drawings which illustrate the embodiments of this invention and in which the same numbers are used to indicate the same parts:
FIG. 1 illustrates a perspective view of this invention, with all its parts combined.
FIG. 2 is a sectional side view of the device, taken on line 2--2 of FIG. 1.
FIG. 3 is a sectional front view of the device similar to FIG. 2, with the device in a position preparatory to use.
FIG. 4 is a sectional view of the device taken on the line 4--4 of FIG. 3.
FIG. 5 is a bottom view of the device taken on the line 5--5 of FIG. 4.
FIG. 6 is a plan view of the handle portion, partly in section.
FIG. 7 is a bottom view of the device's handle portion, taken on the line 7--7 of FIG. 6.
FIG. 8 is a plan view of the round metallic member.
FIG. 9 is a bottom view of the round metallic member taken on the line 9--9 of FIG. 8.
FIG. 10 is a plan view of the snap ring.
In the drawings the number 1 indicates a T-shaped solid handle having a truncated tail 1a, made of circular pieces of metal welded together, the handle 1 is interiorly provided in its truncated tail 1a, with a squared aperture 1b, FIG. 2. The tail 1a is further provided with a threaded aperture 1c in one side, this aperture 1c is designed to receive and hold a set screw 2, FIG. 3, (use position).
The number 3, FIG. 2, indicates a unitary solid round metallic member having one end squared 3a, and having its outer end 3b, relatively larger in diameter than the round member 3, the end 3b being oblongularly hollowed with rounded corners 3c, FIG. 2, on the inside of its larger end 3b.
The body of the round member 3 is provided with two circular indented scores 3d and 3e, disposed and adapted to receive two snap rings 4 and 4a, FIGS. 1, 2 and 3.
The number 5, FIGS. 1, 2 and 3, indicates a unitary, hollow, round, metallic cylindrical member, hereafter called the cylinder 5, having a circularly hollow top section 5a, FIG. 2, which top section 5a is exteriorly hexagonal in configuration, FIGS. 1 and 2, and is designed to receive and hold a wrench and having a section 5b, FIGS. 1, 2 and 3, relatively larger in exterior diameter than the cylinder 5, and situated under the hexagonal end 5a, this section 5b is designed to prevent a wrench from slipping down. The cylinder 5 is provided with a bottom section 5c, FIG. 2, relatively smaller in interior and exterior diameter than the interior and exterior diameter of the body of the cylinder 5, this bottom section 5c is interiorly provided with ridges, forming therein an interior hexagon 5d, FIG. 2. The hollow top section 5a, FIG. 2, is relatively smaller in interior diameter than the interior diameter of the body of the cylinder 5 FIG. 3, both views, and the interior diameter of section 5a is fractionally larger than the exterior diameter of the round member 3 and is designed to receive and movably hold the round member 3 and to allow the round member 3 to move freely up and down in the cylinder 5, FIG. 3, for a distance governed by the position of the snap rings 4 and 4a, installed in the two circular scores 3d and 3e in the body of the round member 3, FIG. 3, (both views).
The mode of use and operation of this invention is as follows:
Install the first snap ring 4a in score 3e, in the solid round member 3, FIG. 2, then push round member 3 into the hollow cylindrical member 5 from the bottom, until the score 3d on the round member 3, is above the top of cylinder 5 and then install the second snap ring 4 in the score 3d, in the solid round member 3, FIG. 3.
Then the T-shaped handle 1 is installed by placing the rectangularly hollowed aperture 1b, FIG. 2, in its tail 1a, over the squared end 3a of the round member 3 and pushing same down over the squared end 3a, of round member 3, FIG. 2. The set screw 2 is then screwed into the threaded aperture 1c in tail 1a of the handle 1, and is tightened against the squared end 3a of the round member 3, until the handle 1 is securely held on the top 3a of the solid round member 3, FIG. 3, (use position).
The invention is then ready to be used as follows:
The interiorly hexagonal bottom section 5d of the cylinder 5, FIG. 2, is placed over the upper nut of a front shock-absorber. The oblongularly hollow end 3c of the bottom section of the round member 3 is manually pushed down by the handle 1, over the stem of the shock-absorber, the handle 1 being attached to the round member 3 as described, the oblongularly hollow end 3c, FIG. 2, of round member 3 holds the shock-absorber stem from turning; the handle is held by one hand during this process.
With the other hand, an open-end wrench is then placed around the hexagonal top section 5a of the outer cylinder 5, FIGS. 1, 2 and 3, and the wrench is turned, which results in turning the outer cylinder 5, then holding the nut of the shock-absorber as described, which very quickly turns the nut off of the shock-absorber and allows the shock-absorber to be removed, repaired or replaced.
The process may be used to install the upper nut on the shock-absorber by placing the nut in the interiorly hexagonal part 5d, FIG. 2, of cylinder 5 and pressing the handle 1 down which results in the oblongularly hollowed section 3c, FIG. 2, of the round member 3 holding the stem of the shock-absorber and then tightening the nut by turning the top 5a, FIGS. 1, 2 and 3, of the cylinder 5, with the wrench as described, until the nut is tightly held on the shock-absorber.
The above disclosure and specification embodies my invention and discovery and all matters contained therein should be deemed to be illustrative and not to be in a limiting sense.
As this invention may be embodied in forms other than, or varying from, my invention, I claim as my invention and discovery all the forms of same which may be deemed to fall within the spirit and scope of my appended claims.
