l o R EN A. Ross ATTORNEYS United The present invention relates to improvements in a socket wrench turning device. It consists of the combinations, constructions, and arrangement of parts, as hereinafter described and claimed.

In the automotive art, it is a conventional practice to employ studs for removably securing wheels in place. These studs are difficult to remove, especially from the heavier types of wheels, due to rusting of the studs and accumulation of corrosive substances. Moreover, these studs must be applied tightly; consequently, considerable force must be used in removing the studs.

Socket wrenches are employed for removing these studs, and mechanics often insert a length of pipe through an opening in the wrench in order to obtain the necessary leverage. However, thepipe bends frequently before the stud will loosen.

In my United States Patent No. 2,577,157, issued on December 4, 1951 on-a Socket Wrench Turning Device, I show a section of a link chain with a wrench-engaging rod at one end and a handle at the other end. The rod is insertable into a transverse opening provided in the socket in the socket wrench, and then the link chain is wound around the wrench. A swinging'of the handle causes the rod to rotate the wrench for loosening the wheel nut. However, the cost of the link chain made the device too expensive to manufacture and sell.

In the present invention, the socket wrench turning device is simplified. In place of the link chain, I provide an elongated leverage casing that has a transverse opening near one end, which is adapted to receive a socket wrench, and has a leverage rod at its other end that extends substantially at right angles to the length of the casing in order that the operator may apply the desired leverage in loosening or tightening the sleeve-like bolts and the nuts of the truck wheel. Moreover, a pin is slidably carried by the casing, and it is mounted in the area lying between the socket Wrench receiving opening and the leverage rod. Therefore, the distance between the casing opening and the leverage rod serves two purposes: one, to create the necessary leverage distance between the leverage rod and the socket wrench; and, two, to provide space to house and protect the pin that is designed to enter a bore in the socket wrench.

A further object of my invention is to provide a device of the type described, which is simple in construction, durable and efficient for the purpose intended. It does not take up much space, and can be carried as a tool for attaching the truck wheel or removing the wheel from the truck axle.

Other objects and advantages will appear as the specification proceeds, and the novel features of the invention will be set forth in the appended claims.

While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made Within the scope of the appended claims without departing from the spirit thereof.

Detailed description In carrying out my invention, I illustrate a transverse cross-section of a pair of standard dual wheels in Figure 1, which are designated generally at A and B. A series of sleeve-like bolts C are used for holding the innermost wheel B in place, and these bolts are threaded both internally and externally as shown in Figure 1. These sleeve-like bolts arescrewed upon studs C and have enlarged double-cone heads Id at their inner ends that bear against walls of openings formed in the wheel B through which the studs C extend. The outer ends of each of these sleeve-like bolts is fashioned with a square head 1. It will be noted that a hexagon nut D is screwed upon the external threads of each of the bolts C so as to bear against the outer wheel A so as'to hold the latter in place. The studs C are anchored to the flange E of the wheel hub, as clearly shown in Figure 1. Thus, the sleeve-like bolts C hold the inner wheel B in place, while the nuts D are utilized for holding the outer wheel A in place. The parts thus far described are conventional.

It will be noted that a conventional socket wrench F is shown in Figures 1 and 2. The right-hand end of this wrench is formed with a socket G therein, with the side walls 2 of this socket forming a hexagon that is adapted to receive the hexagon nuts D. The left-hand end of the wrench F is provided with another socket H, and its side walls 3 define a square designed for receiving the square ends I of the sleeve-like bolts C. The outer surfaces enclosing the sockets G and H are made cylindrical in shape as indicated at 4 and 5,.respectively. These cylindrical ends 4 and 5 serve the purpose hereinafter described. The socket wrench is further provided with a' transverse bore 6 which is placed near the hexagon socket G, while a second transverse bore 7 is placed near the square socket H. The parts of the socket wrench F are conventional and form no part of my invention, except insofar as they cooperate with the parts now to be described.

In Figure 1, there is shown a one-piece elongated stand J, which has one end 8' arranged to rest upon the ground K. The stand, when in this upright position, has a number of steps or ledges 9 and the top step has been illustrated as rotatably supporting the outer cylindrical end 5 of the wrench F. There are usually eighthexagon nuts D to be loosened, when freeing the outer truck wheel A from the sleeve-like bolts C. The nuts D that are on the upper half of the wheel A can be loosened by the wrench F, with the cylindrical end 5 resting on the proper step 9 which is disposed at the correct height for supporting the wrench. The stand I may be inverted, when the nuts -D on the lower half of the wheel A are to be loosened. This will bring the end 10 of the stand I into contact with the ground K, and cause a second group of steps 1:1-to face upwardly and different ones of these will be used for supporting the outer end 5 of the wrench F, as the various nuts D are loosened.

The socket wrench turning device is indicated generally at L in Figures 1, 3 and 4 of the drawings. This device comprises a leverage casing which has two elongated plates M of the same size and these plates are spaced a predetermined distance and lie parallel to one another. It will be observed that three spacing members N, P and Q are placed between the plates M and are secured thereto for holding them together to form the casing. The spacing members N, P and Q have aligned

openings

12, 13 and 14, respectively, for slidably receiving a pin R. The latter may be moved by hand in either direction, and the pin is provided with a head 15, which may be manually grasped for this purpose. A coil spring S may be mounted on the pin R, with one end bearing against the spacing member N, and the other end of the spring bearing against a stop 16 carried by the rod R. This spring yieldingly urges the pin R in a direction to cause the end of the pin disposed opposite the head to enter the opening 14 in the spacing member Q.

As clearly shown in Figure 4, the spacing members P and Q are arranged on opposite sides of a wrenchreceiving opening 17 provided in each of the plates M. These openings 17 are aligned with each other, and the edges of these openings disposed nearest the outer surfaces of the plates M are chamfered, as at 17a, in order to make it easy to move the socket wrench turning device L over the wrench F and have the cylindrical end 5 enter the openings 17.

At the end of the socket wrench turning device L opposite that of the openings 17, I mount a leverage rod T. The latter has an end 18 received between the plates M, and this end is preferably welded or otherwise secured to the plates M. The axis of the leverage rod T extends substantially at right angles to the lengths of the plates M. It will be observed that a tubular or hollow leverage pipe or handle U has a bore large enough to receive the exposed end of the rod T. The handle U may be three or four feet long in order that the operator may exert considerable force in rotating the socket wrench F for either loosening or tightening the sleeve-like bolts C and the nuts D.

Operation Figure 1 shows the socket wrench F as being applied to one of the hexagon nuts D preparatory to loosening this nut. The Wrench turning device L has been applied to the cylindrical end 5 of the socket wrench F, and the pin R has been moved into the bore 7 in the wrench. The exposed end of the cylindrical end 5 rests on the top step 9 on the one-piece stand I. The handle U is mounted on the leverage rod T and the device is now ready to operate.

The handle U is swung for rotating the socket wrench F in a counterclockwise direction for loosening the hexagon nut D. When a half revolution is made by the wrench F, the pin R is withdrawn from the opening 7 to permit the handle U to be returned through a half circle swing, whereupon the pin R is again inserted into the bore 7. Another half circle swing in a counterclockwise direction is made to rotate the nut D through a similar arc.

Usually, only one or two swings of the handle U are necessary to free the nut D to a point where the remainder of the turning to free the nut from the sleeve-like bolt C can be done by hand. Each nut D is loosened in this same manner, and the different steps 9 and 11 are used on the stand I in order to keep the wrench F in substantially a horizontal position. This will allow the outer wheel A to be removed.

When it is desired to remove the sleeve-like bolts C to thus permit the inner wheel B to be taken off, the wrench turning device L is applied over the Wrench F as indicated by dot-dash lines in Figure 2. At this time, the square socket H should face toward the wheel 'B, while the cylindrical end 4 is supported by the stand I The socket H is engaged over the square ends 1 of the sleeve-like bolts C, and the device operated so as to remove these bolts from the studs C. When this has been accomplished, the inner wheel B may be taken oft". The reverse steps are taken when tightening the sleeve-like bolts C and the nuts D for holding the dual wheels in place.
