Abstract
A recording compression testing meter having a measuring cylinder connected to the spark-plug hole of an engine cylinder by means of a tube and having an indicator arm movable by the piston of the measuring cylinder over a portion of recording paper fed from a roll of paper carried in a removable cartridge, the paper being fed from the roll by a drive mechanism carried by the cartridge so that tests of a large number of cylinders can be recorded on the continuous sheet of recording paper fed from the paper roll before it is necessary to reload the meter and the test of the cylinders of each engine can be torn off and stored separately.
