l'o all-urhom'it may concern: Be it knowii tliat I, STANLEY C. Nomar, a citizen of the United .States and resident of Elmira, in the County of Cliemung andA State offNew. York have-invented certain new and .useful Improvements iii Tools for4 'Reinovin'f Engine-Valves of which Ihereby declare the following to be la full, clear,
lOl
and exact description, .suchas will enable others skilled in the ii1`t `to which it appertaiiis to make and use thosame.
'iT his invention relates. to an improved tool for use when makinar re airs to the valves of internal combustionr engines, .or whenfor any. reason 4it becomes` desirable to remove thev'a'lve'sand my objectfis to provide a siinple' and effeetie tool for this purpose -whiclrcan be quickly. and readily applied `to lift the valvespring so as to vfree-the val-ve retaining washer on the valve stern v from pressure, so that itv can be removed, and to `retain the spring in i'aisedposition Vuntil.,tlie'valve has been replaced in opera- .tionposition again. v
I 'attain my .object byv constructing the tfool in the manner illustrated, iii the. accom-` z. an infr drawines inwhichs- Figure. 1 Jie'seiits a .side elevation of the side elevation showing-the tool "ijn-closed.

Likeniiineials,designate like parts' in the several' views.v v
The` tool consists of twoarms l `an'd2 .pivo'ted together hva suitablepin satlone end.. .Attheii' other eiidsthe ai'insare pro` vided with' upper and 4lower. transverselyt Yflattenedprojectionsoi' blades.4 and `5 re" spectively.`
.These` blades arepreferably l pointed at their outward ends and are' proj vwashers used upon valvev stems to receivev 50 vided with Acorresponding longitudinal slots 6, which permit them to passvalve stems of ordinary diameters. .The 'slotLG' on the. upper blade 4 terminates in a circularopeir ing 7 which corresponds in diameter tothe Y'theV springs So that the blade c :aiilpaSbyv the .washer to engage 'the spring engaging =`ring 14 above it intermediate'of the hiige' and" blades. Y A
' An operating lever8 is pivote'd at 9 to the arm 1.l This leverpassesthrough a slota in the arm and is provided between the arms with' an extension 0r link 10 towhich iSA piveted at I; a second link 11 which in turn is pivot-ally mounted at 12 in the'arm 2 thus forming a toggle, by means of which the arms are torcedfapart in operating the tool. The lever 8 is provided with aihandle portion and with a shoulder 1S thereon and 'the arm l with'a shoulder a so formedvthat` arms are brought together as in Fig. 2 and inserted betweenthe supporting ring for the' spring andthe top of the valve'oper'ating rnd a or its guide. In Fig. l'the top of the valve operating .rod is inthe form o'f'an ad justable sei-ew having a hexagonal head 13. When the blades have been inserted with the valve rodpassed into the slot 6 the lever is operated sto spread the arms apartythus. pressing upward on the springring 14 to.
p'usliy itoverthe iaslier17 on `the Valvefstem" li; A-tlia V.opening 7 in the blade 1 permits. the;A
blade to 'pass said washer. vVllieii .the arms are in fully distended position and locked bythe action of the toggle tli'e tool may be the valve stein, as in some makes of engines. When the Vpin has been removed or' the is 'free so that..the valve may be liftedv from its seat' and removed from the engine andv cleaned or repaired. Vlieii the valveis re- A`released and both hands used in removing-' 'the-pin 16 to release the washer 17, orjto Vseparate the part-s of the washergA wherel the washer is divided and set into al grooveon instated and the .washer replaced in posiltion the arms of the tool are thrown to- .getlieig permittingthe parts to expand, and
