Abstract
Abstract A device for lubricating an internal combustion engine with powdered graphite including a housing having an inlet opening for connection with an outlet opening in the crankcase of an internal combustion engine. The housing also has an outlet opening for connection with an inlet opening of the crankcase of an engine together with means for connecting the inlet opening to the outlet opening of a crankcase and means for connecting the outlet opening to the inlet opening of a crankcase. The housing is also formed with a breather opening and has formed internally thereof a series of baffles for collecting graphite in the housing at areas therein prior to the outlet and the breather opening. Further provided is a one-way valve means in conjunction with the baffles for causing collected graphite to exit out the outlet of the housing and into the crankcase as the crankcase breathes.

Claim 1
Independent Claim
181 words
In combination with an internal combustion engine having a crankcase, a device for lubricating the internal combustion engine with powdered graphite comprising: a. a housing connected to the crankcase of the internal combustion engine externally thereof and having b. an inlet opening at one end of the housing for connection with an outlet opening in the crankcase of an internal combustion engine and c. an outlet opening at the other end for connection with an inlet opening of the crankcase of an engine; d. means for connecting said inlet opening of said housing to the outlet opening of a crankcase of an engine, e. means connecting said outlet opening of the housing to the inlet opening of a crankcase, f. a breather opening formed in said housing, g. means in said housing for collecting graphite carried by airflow through the housing from the inlet opening to the outlet opening and prior to said outlet of said housing and said breather opening, and h. valve means for causing the collected graphite in the housing to exit out said outlet of said housing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
28 words
The device of claim 1 in which a. said collecting means includes a multiplicity of baffles secured within said housing between said inlet opening and said outlet opening.
Claim 4
Dependent Claim
52 words
The device of claim 2 in which said valve means for causing the collected graphite to exit out said outlet includes a one way valve located at said outlet of said housing adapted to pass collected graphite from the housing into a crankcase upon upward travel of the piston of the engine.
Claim 5
Dependent Claim
51 words
The device of claim 1 in which said means for causing the collected graphite to exit out said outlet includes a one way valve located at said outlet of said housing adapted to pass collected graphite from the housing into a crankcase upon upward travel of the piston of the engine.
Claim 6
Dependent Claim
61 words
The device of claim 2 in which said collecting means includes a. a wall mounted in said housing, b. said wall having a series of spaced openings, c. A one way valve mounted on said wall at each of said openings adapted to pass collected graphite from the housing into a crankcase upon upward travel of the piston of the engine.
