VALVE-SPRING LIFTER.

Application filed March s0, 1s22. Serial No. 548,097.

To all whom it may concern:

lie it known that I, CLIFFORD C. vYOUNG, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Valve-Spring Lifter, of which the following is a specification.

The object of my invention is to provide a valve spring lifter of simple, durable and inexpensive construction.

A further object of my invention is to provide a device of the kind mentioned having a "forked end adapted to rest on the engine block of a Ford car or the like, so as to allow access to the valve, and having a portion adapted to abut against the block below the valve spring, said device being provided with a pivoted valve spring engaging and holding member and a cam lever for operat ing and locking said last described member.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical sectional view through an engine block, having my valve spring lifter installed thereon, one of the upper arms of the tool being shown in section.

Figure 2 shows a perspective view of my valve spring lifter; and

Figure 3 shows a detailed, sectional view taken on the line 38 of Figure 1.

One of the great purposes of my invention is to provide a valve spring lifter having its parts so constructed and arranged that the device may be quickly and easily installed in position and manipulated for raising the valve spring and left in its installed position with the parts locked for holding the valve spring raised.

The device, which I have constructed for accomplishing this purpose, comprises what I may call a main body, indicated in the accompanying drawings at A, and comprising preferably two strips of metal, indicated by the reference character 10, fastened together by screws or the like 11 having generally the form of a large C, as shown for instance in Figure 1.

At its upper end, the free ends of the strip 10 are spread apart, forming the por tions 11, which areadapted to rest on the top of the engine block 12 on opposite sides arm 14:, one end of which projects forwardly and the other rearwardly from the strips 10,

as illustrated in Figures 1 and 2.

The forward end of the lifting arm lt has the bifurcated fingers 15. Pivoted between the strips 10 above the other end of the arm 14 is a cam 16, extending away from which is an arm or lever or handle 17.

The parts are so arranged that in the actual use of the valve spring lifter, the two members 11 are placed in position on the top of the engine block 12, after the head has been removed. The members 11 are placed in such position as to straddle the valve 13.

The fingers 15 are slid in under the valve spring 18 and the lower ends of the strip 10 are placed against the sides of the engine block, as illustrated in Figure 1.

Th device is then supported in three points and is readily and easily held in position.

The device is thus installed with the arm 17 in the position shown in Figures 1 and 2, extending upwardly. The arm 17 is then lowered to its dotted line position shown in Figure 1, whereupon the cam 16 will engage and force downwardly the rearward end 0 the arm 14, thus raising the fingers 15 and compressing the spring 18, whereupon the pin 19 in the valve stem will be readily accessible, so that it can'be removed for permitting the removal of the valve and its stem 20.

The members 11 are so arranged spaced on opposite sides of the valve and inclined away therefrom, as to permit the manipulation of the valve on its seat, without any interference on the part of the valve spring lifter with the grinding tool or the like.

When the valve has been repaired or replaced or ground, the pin 19 is replaced, and the arm 17 raised to permit the fingers 15 to lower until the valve spring washer 21 rests against the pin 19, whereupon. the valve tally.
