To all whom it may concern:

Be it known that 1, TBA l t/BUCHANAN, a citizen of. the United ,7 States, residing at Yelm, in the countyofsThurstonand State of Washington, have inventedcertainanew and useful Improvements in Valve-Lifting object to provide a simple and easilyvapplied device for the purpose of compressing the valve spring and allowmg the valve to move downwardly to its open position so that itmay be easilyicleaned-orremoved for the purpose of regrinding the valveand its seat. it i It is another important object of the invention to provide a device for the above purpose which is so constructed that bo-th hands of the mechanic are free, whereby the Work may be greatly expedited. 1M1 I It is alsoone of the detail olojeets of the invention to provide a valve spring lifting lever, and an adjustable fulcrum tfo-rsaid lever, Wherebyitanay be operatively applied to motor valves having stems of various lengths.

With the above and other objects in view,

the invention consists in the improved construction, combination and relative arrangement of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate corresponding partsthroughout the several views; and wherein- Figure 1 is a side elevation showing one embodiment of my improved tool as applied in practical use;

Fig. 2 is a section taken on the line 22 of Fig. 1;

Fig. 3 is a plan view of the foot plate of the lifter; and

Fig. f is a detail perspective view of the adjustable fulcrum plate for the lever.

Referring in detail to the drawing, 5 'designates a vertically disposed body bar having a laterally off-set portion 6 formed with a longitudinally extending slot 7 therein. To one end of this bar, a horizontally dis posed handle 8 is integrally connected. The other end of the body bar is curved, as shown at 9, and is formed with a gradually widen- Pate ted June 24, 1919.

iingr"horizontally disposed foot plate 10.

.iThis 110013 plate at t its extremity recessed, .las-zatzll, and formed with a countersink 12 attthe ledge of saidmrecess, which is adapted to receive the lowervalve spring Washer. Thus; lateral shifting movement of: the awasheriplate and its frictional contact with the valve stem 5 or a. rod will "be prevented.

lever l3lextends through the slot? of the i'bod-y bar Stand is fulcrumed 1 upon a I pin F15: conn-ectingithe arms of a bifurcated plate 14, Xbetween which :saidlever extends. A i. ilhOlilli 161 hasr its headed end engaged 1 in the slot 7 and extends through anopening in the opposite end of the plate 14 and through a "reoinciding :opening'inthe washer 17 which is interposed betweensaid plate andthe side '1 ofthe body bar 5. A clamping nut lS of any suitalble type is threaded upon the other end 0f. SELlClllflJOlh to: securely clamp the plate 1 1 .ill'lj itsadjusted position upon the body bar. :adijusting said plate, it will-be readily understoodthat the fulcrum 15 for the lever may be disposed at the requisite distance ifromthe fo ot=plate12so that" the end of the lever13ican e properly applied to the valve springs: j j

iAiring or link 19 is permanently engaged in an eye 20 on the end of the handle 8. T-hedistancebetweenthe fulcrum 15 andthe bolt lo is such that in any adjustment of the plate 14 upon the 'body bar, the lever 13 is normally disposed at such an angle relative to the handle 8 that the end thereof, corresponding to the end of the handle provided with the link 19, is disposed an appreciable distance below said link.

In the application of the device, it will be understood that the foot plate 10 is operatively engaged with the lower valve spring washer, as above explained, and the lever 13 properly adjusted so that its shorter end will extend above the valve stem. The operator now forces the opposite end of said lever toward the handle 8 so that the valve is forced downwardly and the spring compressed. The ring or link 19 is then engaged over the end of thelever 13 so that both hands of the mechanic will be free for the purpose of grinding the valve face or its seat. The device may be very easily and quickly removed to permit the return of the valve to its normal position 'by simply disengaging the link from the end of the lever 13.

From the foregoing description, taken in connection with the accompanying drawlng, the construction, manner of operation and several advantages of the device Will be clearly and fully understood. The several parts of the invention are all of very simple and durable construction and can be easily and quickly assembled or disassembledl Owing to the provision of the adjustable fulcrum for the valve lifting lever, the device can be readily applied to different types of motor vehicle engines. In view of the simplicity of the construction of my improved valve lifter, it Will further be appreciated that the device can he manufactured at relatively small cost.

While I have herein shown and described the preferred construction and relative arrangement of the several parts, it is to be understood that the device is susceptible of considerable modification and I, accordingly,

reserve the privilege of adopting all such legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

I claim 1. A valve lifting tool including a body bar having an angular intermediate porbar having an angular intern'lediate portion and a foot plate extending in one direction from said intermediate portion recessed to receive the valve spring Washer, a handle extending in a relatively opposite direction from the intermediate portion of the body bar, said medial portion of the body bar having a slot therein, a valve spring compressing lever extending through said slot, a fulcrum for said lever mounted upon the body bar, and said fulcrum being provided With means whereby said fulcrum may be adjusted to position the same relative to the foot plate.

3. A valve lifting tool including a body bar having an angular intermediate portion and a foot plate extending in one direction from said intermediate portion recessed to receive the valve spring Washer, a handle extending in a relatively opposite direction from the intermediate portion of the body bar, said medial portion of the body bar having a slot therein, a valve spring compressing lever extending through said slot, a bifurcated plate arranged on one side of the body bar, a fulcrum pin for the lever connecting the spaced arms in said plate, and a clamping bolt for the plate adjustable in the slot of said body bar, whereby the fulcrum of the lever may be positioned relative to the foot plate.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
