A REVOLUTION IN ' AUTO .PISTON RINGS l Manager Byrne of the More Electric company46 East Fourth South street, local lo-cal distributors of Double Seal piston rings, gave out some valuable information informa-tion to auto and truck owners yesterday regarding the value of using properly machined ma-chined and designed piston rings in their motors. He said : "Double Seal plflton packing rins are a revolution in piston and cylinder packing pack-ing and their manufacture marks a new era in automobile efficiency, economy and power. They are the latest word in scientific scien-tific design and mechanical construction, deriving their name from both their form and function. They are property called the 'Double Seal' because they form a continuous ring in the piston groove, the double edge being down and making con- , tact against the bottom face, it seals the; joint in the groove, and also, being double dou-ble around the cylinder, It seals the wall, and it seals them absolutely. Hence the name, 'Double Seal.' "Leaky rings are the prolific source of such motor troubles as loss of compression, compres-sion, loss of power, excessive carbon deposits de-posits in cylinder, causing knocking or' back-firing when stopping the motor, sometimes breaking the crankshaft or bending a connecting rod. "Piston rings are really double-seated check valves and should be made to prevent pre-vent leakage through the inside of the ring, as well as between the outside of the ring and the cylinder wall. "The 'Double Seal' is the only two-piece two-piece ring on the market that seals the openings or joints both in the groove and around the cylinder wall, and that will not leak, regardless of how long they wear."
