' Inventor r Zu/wan @QMmfi-h Attorney Patented Sept. 17, 1929 UNITED STATES CARL J. MURNAN, OF INDIANAPOLIS, INDIANA VALVE REMOVER Application filed July 23, 1928.

The present invention. relates to a valve remover and aims to provide a structure which is simple, durable and inexpensive to manufacture.

A further object is to provide a valve remover adapted to be used on internal combustion engines or motor vehicles, and so arranged and constructed that part of the tube may remain fixed in position with relation to an engine while the other parts may be moved for raising the valve spring or compressing; it in such a way as to permit ready access to the parts of the valve stem.

With the above and numerous other objects in view aswill appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination. and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of the tool embodying the features of my invention showing a portion in section,

Figure 2 is an edge elevation thereof,

Figure 3 is an end view thereof,

Figure 4 is a perspective view of the cam lever, and

Figure 5 is a detail section. taken substantially on the line 5---5 of Figure 1.

Referring to the drawing in detail, it will be seen that the numeral 17 indicates a vertical member having at its lower end two series of openings 18, the series extending longitudinally. At the lower end of the member 17 there is a laterally extending member 19 having a flat horizontally en- Serial No. 294,923.

In connection with theuparts 'just described, there is provided a lever 24 having atone end two parallel cam plates 25, the adjacent ends of which are adapted to straddle the arms 17 so that a pin 26 may be inserted through openings 29 in the plates, 25 and a registering opening is provided so that the wider ends of the plates may engage in the under surface of the arm 22.

,a. spring 27 is d sposed about the upper end of the arm 17 and is anehoredat its upper end as is indicated at 28 to the arm 17 adjacent its juncture withthearm 19 while the other end in'lpinges against the upper end of the bearing sleeve 16.

1V h en the extension 23 is engaged with the recess in the valve head and the end 20 of the arm 19 straddles the valve stem and is engaged with the valve spring it will be seen that by rocking the lever 24 the arms 22 will remain. stationary while the arm 17 is drawn through the bearing thereby compressing the springi'.

I appreciate that numerous tools of. the same general nature have been previously patented but the novelty of my structure] resides particularly in the elongated bear-' ing 16 on the arm 17 in conjunction with the spring 27 and further in the two rows of openings 18 andthe specifically described lei "(if and cam construction associated therewit head valves used in conjunction with detachable heads. It will be noted that my tool has the arm 2-2 with the elongated bearing 16 so that the arm 17 slides therethrough without binding when the pressure of the compressed valve springs is on the tube. i a

The cam lever is an improvement because it pushes down on the arm 17 and is always out of the way and the point where the cam pushes against the arm 22 is nearer to the valve than the other tube thus making this tube easy to operate and having a less tenden cv to cramp the sliding arm 17'.

Furthermore the coil spring 27 is very useful because it keeps the arm 22 against the cam lever after each :valve spring has This tool is especially designed for overbeen removed and thus this arm 22 is in just the right place to slip over the next spring.

It is thought that the construction, operation, utility and advantages of this inven- 5 tion will now be quite apparent to thoseskilled in this artwithout a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what Iclaim as new is:

A tool of the class described including an L-shaped bar formed with a relatively short arm at'right angles to a relatively long arm,

an elongated bearing sleeve slidable on the long arm and having an arm projecting laterally therefrom a spring anchored on the long arm and impinging against the sleeve, a cam lever, means for rockably 3 mounting the cam lever on the long armto engage with the arm of the sleeve, the short arm terminating ina forked end, the arm of the sleeve being offset toward the short arm and terminating in a flat end having an extension rising therefrom, said long arm having two rows of longitudinally extending openings, said cam lever having a pair ofspaced cam plates on one end thereof to straddle the long arm, a pin insertible through openings in the cam plate and through one of the openings of the two rows so that the other ends of the plates may bear against the under surface of the arm ofthe bearing sleeve.

In testimony whereof I affix my signature.

CAR-L J. MURNAN.
