Description:

Abstract:

My invention consists in constructing the piston with a hollow chamber, which chamber is in combination with two "hollow piston- rods, so as to provide a means for the continuous circulation of a stream of cold water through the piston and its rods.

Claim:

The combination, with a piston having an interior chamber, of two separate hollow piston-rods, communicating directly with the chamber of the piston, one of which piston-rods is connected with a water-supply, whereby a continuous stream of water can flow through the piston for cooling the same.
