Improvement in Oil-Cans.

UNITED STATES CLARK J. BROWN, OF PLYMOUTH, NEW HAMPSHIRE.
IMPROVEMENT m OILrCANS.
Specification forming part of Letters Patent No. 129,783, dated July 23, 1872.
I, CLARK J. BROWN, of Plymouth, in the county of Grafton and State of New Hampshire, have invented a certain Improvement of a Self-Checking Oil-Gan Spout for filling metallic lamps, to obviate running themover,
of which the following is a specification:
My invention relates to the combination of a' small metallic tube and gage to a spout of an ordinary coal-oil can, in such a manner that said tube will control the flow of oil out of the can when the oil reaches a certain height in the metalliclamp, as it is very diflicult to see when a metallic lamp is nearly full, or as full as it ought to be without running over.
i The accompanying drawing represents an oil-can, one side of the upper part removed so as to show the attachment. I
A is the reservoir or can. It has only one opening, into which the spout B is screwed. Can A is so put together as to form an airtight chamber when the end of spout B is closed. D is a small curved tube, fastened onto the insideof spout B, extending through spout B into reservoir A. Tube D is bent in such a manner that the end will be above the fluid, and not to strike or interfere in unscrewing the spout B. 0 serves as 'a gage, and is made of a piece of wire soldered to the under side of spout B to regulate the height of oil in the lamp.
. In filling a lamp the spout B is placed into filler of lamp as far as gage 0 permits it; the can A raised sufficient to let the oil flow out. Tube D supplies the necessary air to the reservoir. As long as the oil has not yet reached the end of spout B or end of tube D the oil will continue to flow; but the instant the oil raises to that height the tube D will cease to furnish the necessary air, and the oil as shown.
