1 Claim. 1

This invention relates to garage tools and has more particular reference to a tool for lifting the generator of an automobile motor to tighten its driving belt.

)ne of the objects of the invention is to provide a simplified lifting tool of the type set forth, which will enable a single mechanic to make the necessary adjustments of generator driving belts and fan belts, particularly on V-type motors, without requiring the assistance of a helper.

Another object of the invention is to provide an adjustable lifter of the type set forth, so constructed that it can be used on V-type motors for lifting their generators and a mechanic can operate it with one hand, leaving his other hand free to make the necessary adjustments.

Other objects and advantages of the invention will appear in the following specification, when considered in connection with the accompanying drawings, wherein:

Fig. 1 is a perspective view, partly in phantom, illustrating the manner in which the lifter is used;

Fig. 2 is an enlarged perspective view of the lifter shown in Fig. 1; and

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2.

Referring more particularly to the drawing, the lifter there shown is particularly designed and constructed for use in tightening generator belts by lifting the generators on the motors of automobiles, such as the late model Fords, Mercurys and Lincolns having V-type motors. Heretofore, the job of tightening generator belts and fan belts on such motors has required the services of two men, one to lift the generator and hold it in adjusted position, and the other to tighten the bolts to clamp it in its adjusted position. The work is further complicated by the fact that both the generator belt and the fan belt require adjustment at the same time. The present invention provides a simplified lifter which enables a single mechanic to do the whole job.

In Fig. 1, the preferred type of lifter is shown as being applied to a motor M of the V-type, such as is installed in Ford, Mercury and Lincoln automobiles. It will be noted that the lifter is in the form of a prying tool which has a standard I0, shown as being made of strap metal, and has a forked foot H bent at its lower end adapted to engage the head of one of the stud bolts on a cylinder head of the motor. The standard acts as a fulcrum for a lifting lever l2, shown as being made of a straight piece of strap metal and pivotally connected to the standard by a pivot bolt l3. The lever is shown as having a removable tubular handle 14 which is bent upwardly and outwardly to be operated by one hand of a mechanic. It has a flattened socket to telescope over the outer end of the lever I2, as shown. The bent handle permits it to be operated without striking a fender or other obstacle. The lifting end of the lever is shown as having a curved or saddle-shaped hook l5, also formed of strap metal and welded or PATENT OFFICE otherwise secured to an offset end of the lever to fit under and conform to the curvature of the generator housing. I

It will be understood that such generators are adjustably mounted on the motor housing by means of a supporting bracket having vertical slots in it, and bolts clamp the bracket in its adjusted position to keep the generator driving belt tight. The belt requires periodic tightening, due to wear, and the job of making the adjustments requires a skilled mechanic to avoid the possibility of making the belt too tight and causing undue wear of the water pump bearings, which are also driven by the generator belt.

In the present embodiment of the invention, the standard It is shown as having a series of spaced openings IE to enable the lever l2 to be pivoted thereto at different heights above the foot piece ll, so that the lifter can be applied to generators on motors of different sizes. The lever I2 has a series of spaced openings ll to change the lever arm and enable the lifting fork to reach under generators in such motors.

It will be noted that the lower end of the standard is twisted at a right angle and the foot piece I l is bent at a slight angle so that it corresponds with the inclination of the cylinder head on V- type motors. The twist in the standard also strengthens it against lateral bending.

From the foregoing description, it will be apparent that the tool is very simple in construction and can be made economically. It is also easily applied to motors of various sizes and serves a real need in garages which are short of help.

Obviously, the invention is not restricted to the particular embodiment thereof herein shown and described.

What is claimed is:

A generator lifting tool of the character described, comprising in combination, a standard having a fiat foot piece with a notch in its end adapted to engage one of the bolts on the cylinder head of a motor; a lever pivotally connected intermediate the ends to the standard having a saddle-shaped lifting end adapted to conform to and engage the bottom portion of a generator housing to apply lifting movement thereto, wherein the standard is made of strap metal and is twisted at right angles adjacent to its lower end to provide a foot piece, said foot piece being bent at an angle corresponding to the inclination of the cylinder heads of V-type motors.
