Description

UNITED STATES PATENT OFFICE LEBBEUS W. LATHROP AND THEODORE A. WEBER, "OF NEW YORK, N. Y.
IMPROVEMENT IN ANTI-FRICTION COMPOUNDS FOR BEARINGS.
Specification forming part of Letters Patent No. 165,340, dated J uy 6, 1875; application filed May 17, 1875.
sugar; heat it gradually up to about 400, O
while being rapidly stirred. This process causes the largest portion of the hydrogen and oxygen to escape and increases in same proportion the carbon. Then add to this onequarter pound of graphite for the purpose of toughening. Then press it into solid shape, as desired, for anti-friction bearings.
We claim as our invention- The compound, consisting of carbonized sugar and graphite, as described, for purpose specified. i
