This invention relates to an improvement 7 in valve-springlifters such as are commonly employed for lifting the valve-spring of explosive engines to remove the valvepin, theobject being a simple arrangementof parts whereby the device will remain in position and through which sufiicient force may be easily applied to readily compress the spring for an adjustment of the valve; and the invention consists in the construction as hereinafter described and particularly recited in the claims. V
In carrying'out my invention, I employ a cuplike member 8 either round or rectangular, formed on one side with an outwardly projecting fork 9. (lo-acting wlth this cup is a cap member 10 corresponding in shape to the cup member so as to telescopically slide therein or thereon. This cap member.
is also formed with an outwardlyprojecting fork 11. Within the 'cup and bearing upon the spring-seat collar 17,
