"This invention has relation morespecifically to a device for compressing coiled valve springs of explos'iveenginesY l In regrinding the" intake exhaust valves of explosive engines, and jrefacing" their seats, it is necessary; to remove the: coiled compressing springs. After the'valves have been reground and the seats'refaced:
the springs have to be compressedin order to again mount the same onthe valve stems.
This spring compressing operation not only i v invol vestheexpenditure of considerabletin'ie on the part of the mechanic, but oftentimes bends the valve stems if thes'ame 'arecom'f pressed thereon. j
By means of myspring compressing de-' 7 Vice coiled valve springs maybe quickly compressed to the desiredextent, andheld by retainers in such condition until the same are properly seated and secured on'thevalve stems, thus notonly effecting a considerable,
