' Application le March 3,

.To all wim/m t may concern.'

lle it known that l, 'lnnrono Siinnnnun, e citizen et the United States, residing at lloonoke, in the oountj,T oi loanolte and State of Virginie, have invented eertain'new end useiul improvements in l-elve-Li'tters, of which the 'Following' is a specification.

rlhls invention relates to tools, and the primary object el the invention is to provide en improved tool for lifting and eonipressing the springs oi the inlet ond exhaust vn ves ot un internal combustion engine so as to permit the lconvenient removal of the velves repairs or for the regrinding or the valve seats.

Another object of the invention is to provide on improved valve spring compressor which con he` adjusted and held in any ad justed position so es to permit the springl to be held in e. compressed position While the valve and stein is being removed.

Afurther object oil the invention is to provide a tool 'for compressing' and lii'tine; valve embodying' a pair oi jaws for engag'ingiv the valve spring` ond the valve litt-V rod andan iingroved ineens for edjusting the jews in relation to eeeh other so as toperinit the convenient and easy operation ol the tool.

fr 'turtner object ot the invention is to provide :in innkiroved ineens for operatively'oon`- neef" the adiusti nieohsnisin to tie handles or iones-so to permit the s' ringing oit the handles or aWs in relation to the s.d-V justinko; njieans.

1 still further oh'ieot of the invention is to provide en improved valve spring con,-

sor and lifter oit the shove Character, li is elurslile and in use? one that is siniple and easy to inanuliaoturep end one C-Jhioh een. he nleoed upon the inarliet at e. reasonable cost.

@ther objects and edvantsges ot the invention will appear in the 'following' detailed description token in connection .with the drawings, 'forming s port of this speeltoel'ion, in which drawings:

Referring to the drawings in detail,l Wherein similar reference characters designate ooriespoinfling parts throughout the several views?` the letter nl indioetes tl e internal combustion engine of the ordinary or any iirelierred type molte and lf3 the valve and C the improved tool ier lifting' 'and oompressing;` the valve spring.

The `valve ineludes the valve which is norinallji/7 held in o lowered position for holding' the valve on its seet (not shown) by the compression spring; S, which' is coiled around the stein 5. The lower end o'Q the spring (i rests on the cup shaped sprino' Z which is slidsolv mounted on the valve stein in the ordinary inennerend is held against displeeenient from oil the lower end of the stein by any preferred 1 ineans suoli as e pin or the like. The velve stein is liited in the ordinary manner by the usuel volvo stein rod e hai/ingr the adjusting sereni :ind nuti 9 and l@ arranged on i the upper endwthereot1V tor aljustinil; the stroke et the rod.`

rllhe improved spring' lifter and Coinpressor incl udes' the ps nllel arranged spaced Shanks l1 sind which. have their `inner en'ls lient inwardly toward each other and crossel 13 and then brought out Wsrdly and rearwsrdlv in parallel relation to form the ,operating handles lll a* d' 15. The shfinlrs lll end llivith lthe integral.

handles let and l5 are preileraloly Aformed of" one piece o'i` inetol Whieh is oent along spaced longitudinsl lines to provide the ontwsrdli,1 e-tendinggv edge 'flanges 1G which serve to reintorno tie'shsnlzs ll end l2 with their handles lei and y providing the shsnlrs and handles with the oppositely extending; side Vflanges 1G e substantially Usshaped ooniiguretion in Cross section is ohteinech and these side flanges not only forni rneans for reinforcing and strengtheningt the shsnlts` end handles but also form ineens for ongeging' the valve stein, spring' seat end litter rod. The shank ll and its handle ll is termed its handle l5 and the inwardly lient 'iortion A CD ritl-3 ofthe shank which connects the shank and relire the inwardly extending` bei connecting the shank 11 and the handle The flanges 16 of the shanks are` connected together at this point by a suitable pivot pin 18, as clearly shown in Fig. 2 of the drawings. v

Y The outer terminals of the shanks l1 and V12 are provided with inwardly extending notches 19 and 2O and these notches are adapted respectively to receive the valve stem 5 and the lifting rod- 8. The rearvends of the handles 1a and 15 are also provided with inwardlv7 ,extending notches 21 and 22` in whichVV are fitted fthe oppositely threaded

nuts

23 and 24. rihe rear terminals of the flanges 16 of the handles 11i and 15 are provided with inwardly extending lugs 25 Vwhich are rotatably mounted in suitable oppositely Vdisposed inwardly extending openings 26 formed in the opposite faces of the nuts 23 and 2a.k This permits the nuts 23 and 2a to turn in relation to the

handles

14 and 15 and thus conform to all inclinations thereof.V The oppositely threaded nuts 23 and 2a receive the oppositely threadedv terminals of the vrod 27, the central portion of which carries the adjusting hand wheel 28.

ln operation of lthe improved tool, the forwardend of the shank 12 is slid between `the adjusting screw-9 and the nut 10 of the valve lifting rod 8, and the forward end of the shank 11 is pushed into engagement with the valve stein 5, and below the valve stem seat 7 which rests on the vupper standards of the flanges l1G.` The hand wheel 28 is then rotated so as to bring the `

handles

14 and 15 toward each otherv which will move thek outer ends of the Shanks 11 and 12 in. yopposite directions and lift and compress departing from the spirit or scope of my invention; but,

I claim: l Y

1. A valve spring compressor comprising a pair of members substantially U-shaped in cross section have a body portion and'side flanges, said members each includinga shank,

an offset-handle portion, and aninclined connecting bight portion, means pivotally connecting the bight Vportions together, the outer ends of the shanks having the body portions thereof provided with notches for,

engaging the valve stems, and means ad- `justably connectingthe handle portionsV of the members together for permitting the adjusting of the Shanks toward or away from each 'other and the holding thereof in any preferred adjusted relation.

2. A valve Spring compressor comprising a pair of members substantially Ufshaped in cross section havinga bodyportion and side strength fianges, each of said members cluding a shank portion, an oifset handle portion, and an inclined connecting portion, one of the connecting portions being slotted to receive the connecting portion of the other member, a pivot pin extending through the side iianges of the members at the connecting portions thereof and adjacent to saidV slot, means formed on the outer ends of the shanks for engaging the valve stem,l and means. connecting the outer ends of the handles for permitting the Shanks to be adjusted toward and away from each other.

3. A valve spring compressor comprising a pair of Shanks arranged to engage respectively tlie spring seat of a valve structure and the lifting rod for the valve stem, means pivotally connecting the Shanks together `intermediate their ends, nuts pivotally carried by the rear ends of the Shanks, and an oppositely lthreaded rod threaded into said nuts. Y

le A valve lifter and spring compressor comprising a pair of Shanks having their inner ends bent inwardly toward each other, handles formed on said bent ends, means for pivotally connecting the shanks together at the inwardly bent portions thereof, notches formed in the inner ends of the Shanks, notches formed infthe outer ends of the handles, nuts pivoted in said last mentioned notches, for swinging movement, the bores of' the nuts being oppositeiy threaded, an oppositely threaded rod fitted in the nuts, and a hand wheel on said rod.

5. A spring compressor and valve lifter `comprising a pair of relatively long shanks having handles formed on one endthereof, the Shanks and' handles being formed of sheet metal and having inwardly extending TELFORD SANDEFUR.
