UNITED STATEsf P TENT I QFFICE ROBERT H. HASENRITTER, OF HERMANN,Misso R L IMPROVEMENT IN OlL-CAN N OZZLES.
Specification forming part of Letters Patent No. 174,131, dated February 29, 1876: application filed January 2-2, 1876.
To all whom it may concern Be it known that I,-R. H. HAsENRIT'rER, of H erma'nn, in the county of Gasconade and State of Missouri, have invented certain new and useful Improvements in Nozzles for Oil- Cans; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form partof this specification.
0, which opens into the tube at one end, and
has its outer end closed by a screw-cap d. Passing through this cap is the operatingrod 6, upon which is placed the piston or plunger g, which-moves air-tight in the cylinder. Underneath this piston is placed the coiled spring '6, which is kept in its position by an extension, 0, of the rode, and which spring keeps the piston pressed outward against the cap (1. Inside of the cap 01 is placed asuitable packing, a, which prevents any leakage from the end of the cylinder.
The can having been turned so that the oil will run into the nozzle, by pressing slowly down upon the rod 6 the oil may be made to' drop or run slowly out, while," by pressing the plunger suddenly inward, the oil may be forced outward in a jet or stream.
By means of this invention the spring bottoms of cans,-which are always getting out of order and are so difficult to repair, are entirely done away with, while .almost any sort of a vessel to which this nozzle can be applied can be converted into an oil-can. The only part upon which there comes any wear is the packing of the piston, and this can be renewed at any time.
By making the screw-thread on the end of the nozzle tapering, the nozzle can be applied to vessels having different-sized mouths, and thus, the nozzle being complete in itself, it can be manufactured for the market independently of the vessel to which it may be attached.
Having thus described my invention, I
ROBERT H. HASENRITTER.
