Description: |
| Abstract:
This invention relates to and is an improvement on the peculiar form of up-feed sight-lubricator seen in Letters Patent No. 463,320, granted to me November 17, 1891, and also represented in Letters Patent No. 534,006, issued to me February 12, 1895, and the first part of the present case includes a novel arrangement of pipes, channels, &c., which effectually insures a current of live steam in a 0o downward direction to act as an equalizing-supply that drives the lubricant through the oil-discharge pipe to the cylinder or steam- chest or other part to be greased, while at the same time means are secured not only for supplying steam in an upward direction to the condenser for the purpose of condensation, but to prevent undue flooding of said oil-discharge pipe by an overflow of condense water within the live-steam pipe of said condenser.
Claim:
The combination, in a sight-feed lubricator, of a reservoir; a condenser; a sight-feed chamber; an oil-discharge pipe communicating with said chamber; an external steampipe leading into the base of the condenser; a pipe within the latter, for conveying an upward current of steam; and, near the junction of said steam - pipe and con-denser, a duct that conveys another current of steam down to said oil-discharge pipe. |
