This invention -relates to improvements 13 for the engagement ofthe flange 14C of a in the construction of a valve spring comnut 15 which. is internally threaded or enpressor employed more especially to aciligagement with an arm 16 shaped angularly tate the removal of motor valves, and the in crossA section to prevent vrotation Yf the object of this invention is to provide a simarm in the frame 4and adapted to extend ,55

It is often found diiicult to withdraw the valve spring from position after the valve has been remo-ved and in order that this may be readily done, I have provided a support 34 as shown lin Figure 5 which is bowlshaped or suitably'rounded for engagementv with the valve seat and which is provided with a central hub 35 having an opening 36 therein tov receive and support,i the spindle for lifting the shoe to compress the valve spring, 'after'which the shoe portion 2l and the lower end ofthe valve spring may be swung outwardly by rocking the support 34 von the valve seat due to its curved contour and* they spring removed from the engine by the operation ofthe handle 32 to release the compression of the spring.

Inthe event the spindle 29 might become stuck in position, I have provided a boss 37 on the upper end of the handle 32'for receiv-y ing th'e'tap of a hammer to dislodge any inf crustation and free the spindle in its bearing 28;

It will be further observed that when the arm 16 is placed in the outermosty opening l1 of the' frame it will be engaged. by the extended bearingk leg 38 to support the arm against undue springing of the parts' due to the increased; leverage when thegarm is in this outermost position.

My improved valve compressing device is rvvery simple in construction.` and yet is effective in its operation andl is so,` designed that it maybe quickly appliedtoan engine' 'solely towards the construction illustrated,

butI -desire it to be understood' that I reserve the privilege of resorting to all the `mechanical changes to which the device is susceptible, the invention being deiined and limitedonly by the terms of the appended claims.

I claim: y Y

l. A valve springk compressor comprising a framedisposedat substantially right angles to the. valve stem when usedand having aplurality of spaced apart openings thereyin,anY armcarried by said frame and adapted to be positioned in any one of said openings, means for adjustably holding said arm in its opening, a shoe on the lower end oi said arm for engaging the spring to be oompressed, and a threaded spindle for engagement with the t-op of the valve rotatable in saidV trame for drawing` said shoe towards saidv spindle to compress a valve spring.

2'. A valve spring compressor comprising a frame having a` plurality of spaced apart annular openings therein, an arm angular in cross section adapted to be positioned in any one of said openings, a shoe on the lower end oii'saide arm if'oraengaging the spring to be compressed, and a threaded spindle for engagement with the top otfthe valve rotatable in said frame for drawing said shoe towards said spindle to compress a valve spring.

'3, A valve springcoinpressor comprising a trame havingv a plurality of spaced apart openings with slotsfadjacent thereto,` an arin threaded at its`V upper endz adapted toy be positioned iii any one ofI saidi openings, al nut havinga flangeI adaptedto be positioned inone of said slots :for adjustably supporting said, arm in said frame, a" laterallyeextending foot on the lower end of said' arm, ashoe of suitable length removably securedftolsaid foot `forl engaging the springV to beV com-l pressed, and aa threaded spindle rotatable in said framel for eng/aging4 the upper endloi said valve tov liftI the frame and its lshoe whereby the springmay be compressed.

4. A valve spring compressor comprising a traine having a T-shaped slot' therein with an opening through, said-'frame leading Vfrom said slot and at substantially right; angles thereto, an arm extending throughv saidv op`en`- ing and threaded at its upperendg'anut having a flange in saidslot and in threaded engagement withy said arm vto adj ustably support said arm, abifurcated shoejon'the lower endofl said arm for straddling avalve stein and engaging a spring, and meansffor engaging the upper end yof thevalve and raising said shoe for compressingayvalve spring. In a valve spring compressor, a. shoe having a bifurcated end toistraddle a valve stem, and upstanding projections onl said l end located fory engaging beneath' s'ubstan tiallyv diainetrically opposite pointsoftlie valvespring throughpwhich pressure to said :spring is applied; y

6. In a valve spring compressor, a shoe having a bifurcated end to straddle a valve stem having a recess in said end to lity the lower end of said spring and projections in said recesses located to engage'substanltially diainetrically opposite' points on thelo'wer end of the valve spring throughwhich the compressing pressure ofy the spring is applied. Y n i 7. In a valve spring compressor, a shoe having a bifurcatedendto straddleavalve Kicc i i Vn stem and having a recess in said end to [it the lower end of said spring, and projections in said recesses located to engage substantially diametrically opposite points on 5 the lower end of the valve spring through which the compressing pressure of the spring is applied, said projections being located .in

substantially axial alignment with Ithe Vvalve stem and the point of application of lifting pressure whereby the lifting pressure is applied in alignment with the axis of the Valve stem.
