VALVE LIFTER Filed; March 5, 1929 1 www lullmmllmE Patented Feb. 17, 1931 UNrsn STATES OTTO BLOMBERG, OF CHICAGO, ILLNOIS VALVE l LIFTER Application filed March 5, 1929. Serial No. 344,171.

This invention relates to a valvelifter.

One object of the invention is to provide a valve lifter by means of which the valve may be r'aised from its seat to make possible the loosening of a tight valve spring collar.

Another object is to provide a valve lifter whereby the valve may be lifted in an easy and simple manner for examining and renewing the tappet screws.

Another object is to provide a practical valve lifter having a selective arrangement of parts whereby the litter is adapted for universal use on motors of various sizes and styles.

Another object is to provide a valve lifter in which the various operative parts cooperate to provide a balanced action and in which the litter when moved beyond a given point will remain in any adjusted position when released.

Another object is to provide a valve litter to meet the various requirements for the intended use.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in whieh- Figure 1 is a side elevation of the valve lifter, shown in operative association 'with valve mechanism of an internal combustion engine;

Figure 2 is an end view of the same valve lifter;

Figure 3 is a sectional View taken in the plane of line 3 3 of Figure 1; and

Figure 4f is a detailed enlarged view of fastening means for some of the adjustable parts.

The various novel features of the invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, it will be noted that my valve lifter includes a relatively stationary main body member having a vertical leg 10 and a horizontal leg l1. Slidably or movably mounted with respect to the main body member 10 is a horizontally extending member 12 having adjustably and detachably connected to its outer end an extension member 13, the outer end of which is forked at 14L to straddle the lower end ot the associated valve stem 15, and more particularly, to vunderlie the valve spring washer 16'. The inner end of the movable member 12 is secured at 17 and 18 to a slide'member 19 which embraces and is slidably mounted upon the vertical leg 10` of the main body member. A link 20 at its lower end is connect-ed at 18 to the slide 19 and the upper end of said link 20 at 23 is connected to the spaced arms 21 of a hand lever 22. By actuating the hand lever 22 from the dotted line position to the full line position shown in Figure 1, the movable member 12 of the lifter'will be raised for compressing the spring 24 surrounding the valve stem 15.

rlhe forward end of the horizontal leg 11 oi the litter is provided with an extension 25 having a plurality of

openings

26, 27 and 28. Mounted in the lirst opening is a valve engaging member 29, the lower end of which is pointed for engaging a complementary part in the upper part of the associated valve 30. Not only is the valve engaging member 29 slidably mounted within the opening 26, but it is also slidably mounted within an elongated groove 31 of a bolt 32 which may be drawn and tightened by a wing nut 83 mounted upon its threaded end for regulating the frictional gripping action of said bolt upon the rod 29. It is intended that the rod 29 shall have a slipping movement in the relatively stationary member of the lifter to permit the whole valve 30 to move upwardly, as the spring 24 is compressed, in the event that the valve spring collar 16 is rusted or otherwise stuck to the valve spring segmental collar key 34: which is mounted within a reduced portion or groove 35 in the valve stem 15. Also by permitting the rod 29 to yield, distortion of the valve lifter is prevented.

1t is necessary to have a fixed ulcrum for the tool. ln this connection, there is provided a fulcrum including a saddle-shaped member 36 which overlies the valve 30 and having an aperture through which the rod 29 extends. Extending upwardly from the saddle is a rod or holder 3'? which extends through the opening 27 in the stationary valve lifter member and which is secured in fixed posi- Il( LA P1 La tion with respect to said member by a lock bolt 38.

As shown in full lines in Figure 1, the levei` 22 has been moved into a position to raise the relatively movable valve litter meniber 12 ior compressing the valve spring 24. Normally the bottom ci the valve stein would remain in engagement with the head of the associated tappet screw 39, but it' the spring collar 16 is rusted to the valve spring collar key 35, not only will the valve spring 24 be compressed but the valve will move upwardly, provided the rod 29 is permitted to yield under pressure. rlhis the rod is adjusted to do. 1il-litii the valve 30 thus raised, it will be apparent that the rusted collar 16 and the valve spring collar key may be separated by delivering a blow upon the head of the rod 29 whereupon the segmental valve spring collar liey 24 ina i be removed from the stem and the other parts dissociated.

By this saine arrangement, the valve spring may be compressed, leaving the valve iii a free or ioating position so that the tappet nuts 41 and tappet screw 3S) may be adjusted, removed and renewed.

As shown, the valve lifter is associated with an internal combustion engine 42 having a manifold 43 extending outwardly quite a distance from the body ot the engine 42. Under such cii'cuinstances, it will be noted that the extension member 13 is just substantially at its outer position and the rod 29 occupies the outermost opening 26 in the extension member 25. It the manifold 43 does not extend so t'ar out, it will be appreciated that extension member 13 may be adjusted to a position inwardly from that shown and the rod 29 transferred from the hole 26 to the hole 2S, in which event the saddle 36 will be swung through an angle of 180 so that the opening 44 vvi'll be in a position to receive the rod 29 when it is releasably locked in the opening 28. This makes the tool universal for manifolds having various sizes.

There may be various modifications of the invention as herein particularly shown and described, and it is my intention to cover all such modiiications which do not involve a departure from the spi `it and sco-pe of the invention as defined in the following claims.
