UNITED STATES PATENT OFFICE.

CHARLES B. UN DERHILL, OF LANCASTER, NET YORK.

oit-CAN.

SPECIFICATION forming part of Letters Patent No. 459,320, dated September 8, 1891.

Application filed October 31, 1890. Serial No. 369,974. (Nolmodel.)

To a/ZZ whom it may concern.-

Be it known that I, CHARLES 13. UNDER- HILL, of Lancaster, in the county of Erie and State of New York, have invented a new and useful Improvement in Oil-Cans, of which the following is afull, clear, and eXact description.

My invention relates to oil-cans, and has for its obj ect to provide such cans with means whereby when the can is comparatively'empty a small quantity of oil from that left therein may be forced out with equal facility and power as when the oil nearly fills the can, and whereby, also, the moment the springbottom of the can is released the air-inlet will be automatically opened, which inlet has no connection with the nozzle, and at the same time produce a can which may be used in any position.

A further object of the invention is to simplify the construction set forth in the patent for oil-can nozzles granted to myself August I27, 1889, No. 409,311.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim. 4

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in both the views.

Figure 1 is a central vertical section through the improved can, and Fig. 2 is a horizontal section taken on the line cc @c of Fig. 1.

The body 10 of the can maybe of any suitable contour and is provided with the usual spring-bottom 11 and an interiorly-threaded neck 12, surrounding an opening formed in its upper end, through which opening the oil is introduced into the body. At the bottom of the opening surrounded by the neck 12 a strainer 13 is located, whereby the oil is'iiltered before entering the body of the can.

The upper opening of the can is closed by a cap A, which cap virtually comprises an upper knob-section 14 and a lower annular eXteriorly-threaded flange-section 15, the latter being screwed into the threaded surface of the neck 12, as shown in Fig. 1. Theknob- 5o section 14 of the cap has a vertical chamber 16 formed therein, which extends through the upper end of the section, and an aperture 17 connects the chamber 16 with the space within the flange-section of the cap, as is likewise best shown in Fig. 1.

A valve is iitted in the cap, consisting ot' a stern 1S, which passes upward through the aperture 17 into the chamber 16 and has attached to its upper end a plug 19, which plug is preferably screwed upon the stem, and is of a diameter approximating the diameter of the chamber and of the disk 21, secured to the lower end of the stem and adapted to close the aperture 17, below which it is located. Between the base wall of vthe chamber and the under surface of the plug aspring 20 surrounds the stem, which spring normally forces the stem upward and causes the disk 21 to normally close the aperture 17 /Vhen the bottom 11 is pressed, it forces out more or less oil, and when the bottom goes back there is a vacuum produced in the can, which causes the valve to open and admit air. Air is admitted into the chamber 16 through side vents 22, and when the valve is in its normal position the air passes downward through the aperture 17 into the body of the can. The moment, however, that the necessary air has passed into the can the disk 21 is forced upward and closes the aperture 17.

The nozzle 23 is located at one side of the can, and to that end a vertical tube 24 is formed integral with the side of the body and interiorly threaded at its upper end, and the nozzle 23 is screwed into the said tube. The nozzle 23 is provided with a tubular extension 25 atits lower end of considerably less diameter than the diameter of the tube 24 of the body into which it projects, the tubular eX- tension 25 being of such length that when the nozzle is screwed to place the lower end of the said extension will be but a short distance removed from the spring-bottom of the can, as is clearly shown in Fig. 1. As the nozzle is located at one extreme side of the can-body and extends downward to Within such ashort distance of its bottom, it is obvious that almost the last drop of oil contained in the can may be forced out through the nozzle and with the same degree of facilityand power as if the can were comparatively full. Thus the oil-can may be more readily manipulated IOO than if the nozzle were located at the center of the body, and a great economy of oil is obtained.

Having thus described my invention, I claim as 1pew and` desire to secure by Letters Pat.- en

As an improved article of manufacture, an oil-can provided with a spring-bottom, an opening` in its upper surface, a tube constituting a port-ion of one side of the can-body, a nozzle secured to the tube and extending within the oil-can at its lower end nearly to an engagement with the spring-bottom, acap
