Abstract

629,192. Valve accessories. CLOUDSLEY, J. L., and OYSTON, W. R. May 7, 1947, No. 12412. [Class 135] [Also in Group XXVII] A valve spring support comprises two conical annular members 2, 3 fitting coaxially one within the other and united at their peripheries as by a flange 2a and finger-pieces 4 slidably entrapped between the members 2, 3, these finger-pieces being symmetrically inclined with respect to the axis of the complete spring support and having radially disposed upper ends 4b which are moved into engagement with a shoulder 1b on the valve stem 1 when the fingers are moved bodily upwards with respect to the conical members. Such movement is effected by the lower ends 4a of the fingerpieces which project through slots in the flange 2a on the inner conical member. The fingerpieces are released by a conical ramp 1a on the valve stem when the spring support is pressed upwardly against the valve spring.
