GB Patent: 189,730,636 http://www.datamp.org/patents/displayPatent.php?id=55970&pn=189,730,636 Improvements in Sight-feed Lubricators Patentee: James Lionel Grandison - Manchester England Granted:1898-10-29
Manufactured by Steam Cylinder Lubricator Co., Ltd. - Manchester England

Note: Early English patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January. The patent # used in DATAMP represents the year of issue and the patent #. This patent is #30,636 of the year 1897. Abstract: The condenser e is mounted on the reservoir a, and the sight-tube b and a gauge glass are on opposite sides of the reservoir. A pipe leads from the top of the reservoir to the bottom of the sight-tube. A passage h in the top of the reservoir connects the sight-tube with the oil-delivery pipe k. This pipe k projects through and beyond the end of the pipe m, which screws into the steam pipe and admits steam to the condenser.

Manufactured by Steam Cylinder Lubricator Co., Ltd. - Manchester England

Note: Early English patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January.

Abstract: Lubricators, sightfeed, specially suitable for cylinders of air-compressors but applicable also to steam engines. Oil passes through the passage p, controlled by the valve g, to the nozzle m in the sight-tube l. In order that the pressure above the oil may be equal to that below it, a second passage p<1>, controlled by the valve h, is provided. A tube q extends from the passage p<1> to the top of the oil vessel a.
