AUTO-VALVE LIFTER.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed August 25, 1919. Serial No. 319,524.

To all whom it may concern:

Be it known that I, Enunn E. I'IARRIS, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Auto-Valve Lifters, of which the following is a specification.

This invention relates to devices for lifting automobile valves, and the principal object of the invention is to provide an adjustable device adapted to be placed between the spring cup of the automobile and an adjacent part of the engine so that it is not necessary to provide suspending means for attaching the device to a part of the engine as is now the case.

Another object of the invention is to provide two jaw members and a third member provided with a wedge part for forcing the jaw members apart.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a View of the invention with the jaw member in closed position;

Fig. 2 is a view of the device with the jaws in open position;

Fig. 3 is a top plan view;

Fig. l is a bottom view;

Fig. 5 is a section on line 5-5 of Fig. 2;

Fig. 6 is a section on line 6-6 of Fig. 2.

In these views 1 indicates the stationary or main jaw member which is provided with the handle part 2 and the ears 3 which are located intermediateits ends. 4 indicates the movable aw member which has its rear end curving downwardly and is pivoted between the ears, as shown. Each jaw part is forked, as at 5, to receive the valve stem and the outer face is roughened or corrugated as at 6 to prevent slipping. The main jaw part is provided with the rack teeth 7 and the movable part is provided with the semicircular grooves, and said movable part is also provided with a curved recess 9 on its inner face which is formed by curving the jaw part as at 10. This movable part is slotted, as at 11 and the shank 12 of the actuating member 13 passes through this slot. This actuating member carries at its end the wedge-shaped block 14 which is rounded at its upper end to engage the grooves 8 and recess 9 and has a square edge at its lower end for engaging the teeth 7.

The parts are assembled by passing the shank of the actuating member 13 in the slot 11 of the movable jaw 4 before the same is connected to the ears. Said movable jaw is then pivoted to the ears so that the parts are all connected together. In using the device the actuating member 13 is swung upwardly so as to permit the jaw members to contact with each other as shown in Fig. 1. The ends of these jaw members are inserted between the spring cup and the adjacent part of the motor and then by pressing the actuating member 13 downwardly to cause the block 14 to assume a substantially vertical position, the jaw members will be forced apart and thus raise the cup and spring to permit the removal or replacement of the pin which holds the cup in position so that the valve may be removed. The device may remain in this position while the valve and its seat is being ground. It will be seen that by placing the block in the different grooves and teeth the extent of movement of the jaws may be varied. lVhen the jaws are closed the block will engage the recess 9.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

lVhat I claim is 1. A device of the class described comprising a pair of jaw members, a handle connected with one member, an actuating device slidably connected with one jaw and means carried thereby for forcing the jaws apart.

2. A device of the class described comprising a main aw member having a handle connected therewith, a movable jaw member pivoted to the main jaw member intermediate its ends, an actuating member, a block thereon engaging between the members and adapted to be tilted by the actuating men1- ber for forcing the jaws apart.

3. A device of the class described comprismg a mam aw member havmg a handle thereon, a movable aw member plvotecl to said main jaw member and having a slot 5 therein, said members having recesses formed thereln and an actuatmg member extencllng through sand slot and havmg an enlargement at its end resting between the jaw members and adapted to engage the reeesses When the acne-ting member is moved 10 to force and hold the jaws apart.

In testimony whereof I affix my signature.

ELMER EARL HARRIS.
