MATTHW F. vMAURY, OF RICHMOND, VIRGINIA.
IMPROVEMENT IN PNEUMATIC SPRINGS.
Specification forming part of Letters Patent No. 125,7 49, dated April 16, 1872.
Specication describing a Gar-Spring, invented by MATTHEW F. MAURY, ofRichmond, in the county of Henrico and State of Virginia.
The invention will rst be described in connection with all that is necessary to a full understanding thereof, and then be clearly pointed out in the claim.
Figure l is a plan, Fig. 2 a vertical central section, and Fig'. 3 a side elevation of a pneumatic car-spring.
A represents the lower and C the upper section, the upper sliding up and down in the lower.
Pneumatic springs have long been used in machinery, but the great obstacle to their general employment has been the inability to secure a packing sulicently tight to prevent the escape of'air when under pressure. I think that I have accomplished this object in a perfect and economical manner as follows:
I construct the lower section A with a central and upward convexity, A', which produces a narrow channel, a, between it and the wall of said section. I till this channel with oil or other equivalent substance, while into the up.
per part of the chamber formed by the two sections is forced the proper quantity of air or other gas. The lower edge of the upper In pneumatic springs, I claim the oil-channel a, applied as and, for the purpose set forth.
MATTHEW F. MAURY.
