VALVE-SPRENQ LIFTER.

Appliceiion filed. spill 2'7, 192%. Serial .l'lo. 'vveeeo.

Z '0 aZZ whom it may concern:

Be it known that I, FRANK M. BUTLER, e citizen of the United States,- residing at Elke, in the county of Ellie eild State of Nevada, have invented certain new and useful limprovemenl; in Valve-Spring Lifters, of which the following is e. specification, reference being had therein to the accompanying drawing.

This invention relates to valve lifters and has for its principal object the provision of a device of this character adapted for lifting the valve spring for removing the cross pin, for raising the valve to remove the same,

endlfoz' removing the valve spring.

Another object iesioes in the provision oi means for holding the j awe of the lifter either in closed or open position.

With these end, other objects in view, my invention consists in she novel details of construction em errenge'nent of parts which will be move clearly understood from the following specification and drawings, in

which Figure 1 is a. side elevation showing the initial position of the valve lifter.

Figure 2 ise side elevs'eion of the valve lifter showing the'spring pressed for re movsl of the cross pin.

Figure 3 is is top plan view of the valve lifter.

Figure 4 is a detail jaws of the velvelifter.

In can ying out my invention 1 provide the levers A and B which are pivotelly con:

perspective of the nested as l. The lever A. is curved as shown and one en is provided with e hifurcstecl jaw 2, the under side of. which if proviclecl with teeth or comiigetions 3. The opposiiso of this level" A is foi'mell with the righv angle extensions 4 for purpose to he later described. v

The lever B is curved, as shown, w provide a recess 02' concevecl porlgion will, adjeeemfi the pivot poise 1. Cone soil of ihis lever B is pro ided with. e bifurcated jaw e, "she upper fees of which. is provicl'ecl with '2 The opposite sell o f ihis lever provideclfvvilsle the sigh?) angle extension 8, eclsififleel to oooperete with the extension on the lever A fee? e purpose to be later cle'scrilaed. Theends of the levers having the eight angle exieiisioes slightly offset towards another, as shows el' 9,

the veelh, or ooiiqugeiiess' ss olhei the end of the lever will, Q'verlie the end of the lever A. The encl of the lever B having the bifurcated jaw is also slightly curved, as shown at 10 and offset so thee the jev; 6 will overlie she isvv of the lever A. h i

A ring 11 enciroles the levers anti will normally rest in ihe'recess 5 formed in the lever B. This ring may be slid in either direction on the levers encl if iowercls ehejews will hold the jaws in closed position, while if 66 iowards the opposite ends will holol the jaws 111 open position. The jaws 2 enol 6 will prevent the ring from sliding off one end of the lovers Whereas the right single extensions and 8 will preve'nfi it opposite end.

'lVhen in use the bifurceted .3; ewe 2 and 6 will behroughi together and foreecl between she casting 12 and she piste 13 carried on the valve seem Ll. "lhen by pressing on ihe opposite encls of the levers, the jaw 6 will be raised and will compress the coiled spring 15 surrounding the valve stem" 1-2;. When the spring has been compressed to the desired point the ring 11 will he slid tovverdsw the ends of the levers having the right engle extensions l ancl 8 end will hold the jevvs open so thee the cross pin' 16 may he re moved from the valve stem. After the pin has been renioveal the ring 11 is again slid into; the recess 5 and the spring 15 is allowed to expend and carry the plate 13 downwardly on the jaw 6. When in its lflwflli most position the plate 13 will engage under the encl or" the valve stem 14 and then by again opeistiiia she levers to reoompress the spring, the vel ve 17 will he raised and can; he removed. Aile the valve has lo'eeirfe} move& she spring will egeizg. he ellowecl to expand and by slightly lilting the lovers the spring. may he removed.

From the above detailed description it will. he seeii. thee I have provkleol 9. tool which may he used for lifting the-valve springfoiremoving she cross pin from the sem,.:for removing} the valve, and for .re moving the spring. ll; will also he noted iiheiimeeiis have been provided for holding the jevvs either in closed or open position so she-t the hsncle of the user will be freefor removing ville cross pip, valve, or spring. having the ones ofthe levers oi'l'eet, es

' shown all; 9, the movement of fiche levers will be limited is will he imgoessihlelov she end of she levee pose one from sliding on? the) or the lie lever A. By curving and olisetting the opposite end of the lever B, the java will overlie the jaw of the lever A. Particular stress is laid on the provision of the recessed or concaved portion 5 in the lever B which allows the ring 11 to be so held, when not in use, as not to inter-fer with the manipulation of the levers. The teeth or corrugations on the jaws will allow the jaws to have a more secure grip.

While I have described the preferred form of my invention, it will be understood that minor changes may be made in the construction without departing from the spirit of the invention.

. Having fully described my invention, What I claim as new and desire to secure by Letters Patent is .form a recess adjacent the pivot, and a ring normally received in the recess but adapted to he slid towards either end of the levers. 2. A valve litter comprising two levers pivotally connected intermediate their ends, one of said levers being curved upwardly towards each end, from the pivot point, to form a recess adjacent the pivot, an enlarged bitur' cated portion on adiacent ends of each lever, an outwardly extending projection formed on the opposite ends of the levers, a ring normally received'in the recess but adapted to he slid towards either end of the levers, the movement of said ring being limited in one direction by the bifurcated enlarged ends and in the opposite direction by the outwardly extending projections.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.

FRANK M. BUTLER.
