This invention relates to improi-fements in two arms and 6 which extend at right valve litters. Y y K v angles to each other. V rlhis member is ar- In repairing automobile.engines and esy ranged with the base oi' the- U towards the peciallyfivhen the valves are to be ground or inside. The end ot the arm 5 is cut diagonal 60 i', removed forthis or any other purpose7 it is ly inv the manner indicated by line' p and necessary to compress the valve springs so terminates in projections Sthatare perfothatj `thep'ins orother means may be re-` rated for the reception ot therivet 9 which movedirom the valve stems. in some makes is adapted to engage the notches in the oi automobile engines the valve springs are bar 11. lt will be noted fromFig. 1 that if. 65 l0 very powerfuland can be .compressed only the end of the arm 5 were cut at right angles by using'tools especially constructed tort linstead of on a diagonal that the member this purpose.: y 11 could not be moved Without irst removing- It is` the object 'of this invention to prothe rivet7 but by the simple expedient of the Y Y duce a :valvejcompressor which shall be so diagonal cut it is possible jto remove the70 constructed that it can be employed for comrivet 9 from the notch lO'by merely moving `pressing the springs on any motor and which the bar 11 downwardly out of alignment into shall be adjustable to any size necessary. In the position indicated by the dotted line 12. addition to this it is a further object of this A iiat metal loop 13 encircles thearm 5 and invention to produce a vdevice that can be when it is in the position shown inl? ig. 1 75 ,20p readily assembled and disassembled so that the part 11 will be positively held against it will occupy only a smallspace and Which relative movement with arm 5. The outer` can therefore'be readily packed and carried end ol bar 11 is enlarged vas indicated by in `the jivorlrn'ians tool box. The above and numeral 14 and is provided Wit-h a threaded other object that Will becomeapparent as the opening 15 for the reception of the threaded descriptionproceeds are attained by means of tubular member 16. This member has a a constructionthat will Vno'W be described in diametrical slot 1? that extends downwardly v detail, reference for the purpose being had to from the upper end. A vcam '18 is pivoted the accompanying drawing in which the preat 19 and is provided with a handle f2() by ferred form of this invention hasbeen shoivn means olZ which it can be rotated vabout the 85 and in which: v l 1 v pivot. rlhe extreme end of the cam 18 is Fig. 1 is a side elevation of the valve litter, providedwith a head or thickened portion parts being broken away to better disclose 2'1 which serves as a stop when it engages the constructioin a portionof thevvalveeand the bottom ot' the` depression or notch-22 valve spring beingshown for the purpose or" Slidable Within the tubular. member 16`is a 90 illustrating the'manner oifusingthe lifter;` plunger 23 of smaller diameter than the FigQ is a section taken on aline that coropening in the tubular member.'` The responds to lineQ-Q, `Fig. 3; upper end 24 oi" this plunger has sub- Fig. 3 is a "section taken ron line 3 3, stantially the same diameter as the open# y Fig. 2; f ing in the tubular! member 16.

The upper end that is tobe compressed. As the construcof the cylindrical portion 2e? has a transV tion ofthe engineis immaterial for the purverse slot Q9 Within which' is pivotedr the 105 poseyof illustrating this invention, it has not roller 30 Whose periphery is forcedV against been shown'buta portion thereof hasbeen ythe outer surface oi the cani 18 by the acindicated by Vadotted line that has been tion of thel spring 27.. The cam 18 has a designated byV numeral3.'v notch 31 near its tip for the reception oit The* spring compressor is formed from the roller 30 (Figs. 1 andQ). It is now H0 'several parts and consists ot-a member of evident that when the cam 18 is moved Ushaped cross section. Thisv member has from the position shown in Fig. 1 to that Cil shown in Fig. 2, the plunger will be projected Jfrom the tubular member. Secured to the arm G in exactly the same manner as bar 11 is secured to the arm 5 is an angular connecting member l? having armsQ and 32) each of which has notches l0a 'for receiving and cooperating with the `rivets Sr. Flat metal loops 13 surround the arm (3 and the U-shaped connector Bet andv operate like the loop 13 to hold t-he parts in alignment. Secured .to theend of the connector Si is a removable part 35 whose outer end is forked andcomposed ot two areuatearms ilo. Attached to the. arms 3G by means of pivots 37 is a U-shaped abutment 3S formed from a` pieceof metal pressedv into an l..shaped cross section. The lower `end ot' the spring` 2 rests on the upper surface. ot the member 38. i n Letns nowassume that the parts are assembled in the ymanner shown in Fig. l and that it is desired to compress the'spring so as to remove the pin or other means that is employed `for holding the valve-in place. The U-shaped member 8S is placed underneatlrthe lower end ot ,the springT and the sharp end oi the plunger Q3 is put into position against the upper endfofvthe valve. rlhe handle Qtlis now grasped and moved from the position shown in Fig. l `to that shown in Fig. 2 .whereby the cam 1S moves the plunger downwardly .and thereby7 decreases the distance between the end of the plunger and the member BS'thei-eby compressing` the spring.

Then the tool is not in use it may be separated into tive parts and can then be placed in atool box along with the other tools of the kit. I have shown the member 35 as being,` separate .from vthe part 34 but/this is not necessary as they may be formed from a singlepiece it desired.

llVhen the device is to be used lor different makes of engines it may be roughly adjusted by moving the parts 32, 4,11 and relative to each other until the device assumes the proper size. By turning the 'tubular member 16 it may be adjusted to the most desirable position.

Havingnow described my invention what I claim as new is:

l. valve sprinzgr compressor comprising a trame having two parts, each o't which has two arms extending` at right angles to each other, one oit said parts having a chan nel along its outer surface, which is'adapted to receive the other part, the ends ot the channeled part. to which ythe other part' is attached being' cut diagonally so that'the closed side` shorter than the open side,y the tips oi cach ol the end portions ot said channeled parts being connected by a rivet7 the other part ha ving a width substantially equal to the depth ot the channel and-having its outer edge provided with notches adapted to be engaged by the rivet when the parts are in aligned position and from which ythe rivets become disengaged when the parts are moved aneularly with respect to eachother. Y 2. .A valve .spring` compressor' composedot tive separate relatively movable and adjust-r able parts,-two ot' which are of belll crank shape and the others substantially straight", one oitE said bell crank shaped partsl having a vU-shaped cross section with theopen side' towards the outside whereby a channel is formed, and the other havingr a rectangular cross `section and being of the proper size to tit the channel ot the section having the oshaped cross section means lor holdingr the two bell crank memberstogether so as to form a ytrame havingl parallel side members, `a threaded plug,` a` member adjustably connected with each ot said parallel side members. one of said members having a threaded opening', for the reception ot' the threaded plu;r and a U-shaped sprinrr engaging' means attached to the outer end ot thecothery adjustable member.
