This invention relates to improvement in ready path for the transference of heat from removable valve-cages for either the intake the seat to the cylinder head. or exhaust ports oi an internal combustion en- Another factor responsible for the close gine particularly designed `for air-cooled encontact between the neck of the valve-cage, gines. The object of this invention is to prothe annular valve-seat, and the cylinder-head, vide a valve-cage which `may be readily reresides in the fact that in operation the three movable if desired but which will closely tit parts in the order named are maintained at the cylinder head to which it is attached, ant diii'erent degrees of temperature, for instance, the invention consists in the construction as the Valve-cage being maintained at the highhereinafter described and particularly recited est temperature the valve-seat at the interme- 0u in the claims. i diate temperature; and the cylinder-head at In the accompanying drawings: the lowest temperature, relative to the others, Fig. l is a sectional view illustrating a res0 that the highlyheated neck of the valvemovable valvecage for internal combustion Cage expands to a relatively-great degree engines constructed in accordance with my and tightly engages the inner periphery ofthe ce' invention; and valve-seat which, Ain turn, is stretched int-o FigQiSaperspective view of the valve-seat close engagement with the opening lin the detached. cylinder-head by the expansion of the said In carrying out my invention I employ a neck.
