The spring may be removed and replaced,.the device act- Having thus describedmy invention,what .I claim as new and desire to securebyLee tersPatent, is: 1. A valve spring compressing device comprisinga yoke-like bodyjhaving parallel." arms with opposed'iinwardly projecting". 4

spaced spring engagingfingers'at their outer ends, the cross member of said body being longitudinally slotted, a bifurcated" thrust member provided witha cross member slidably engagingthe arms of'lthe body, the legs ofsaid thrust'member terminatingin outwardly-projecting spring engagingfeet; slidably engaging the arms of said body, anda-n I eccentric pivotally mounted in the said slot;

tocoactwith said cross member and provided with a handle and with a plurality of-spaced e lecti vely engaged to vary the throw of said Q eccentric; the outerof said holes benig elonpivot holes with which the pivot may be segated facilitating the engagement ofthe'pivot thrown by the center. i

therewith and permitting the eccentrichtobe I legs of said thrust member terminating in outwardly projecting spring engaging feet slidably engaging the arms of said body, and an eccentric pivotally mounted in the said slot to coact with said thrust member.

' 3. Avalve sprin compressing devic egcomprising a yoke-like body having parallel arms with opposed inwardly pro eeting spaced spring engaging fingers at their outer ends, the cross member of said bod being longr tudinally slotted, a bifurcate thrust member provided with a cross member slidably eiwa projecting spring engaging feet slidably engaging the arms of said body, andan eccentric pivotally mounted in the said slot to 00- act with said cross member and rovided with a handle and with a plurality c spaced pivot holes with which the pivot may be selectively engaged to vary the throw of saideccentric.

In witness ,whereof I have hereunto set my hand. i
