SPECIFICATION forming part of Letters Patent No. 780,472, dated January 17, 1905.
Application filed October 14, 1903. Serial No. 177,069.
To @ZZ whom, it may concern: Be it known that we, JOSEPH BARDSLEY,
residing'at'Montclair, in the county'of Essex,l
and THOMAS N. MON ISH, residing at Kearney, inthe county of Hudson, State of New Jersey, citizens of the United States, have invented a new and useful Oil-Can, of which the following is a specification.
Our invention relates to oil-cans and fluidcontainers of various kinds; and-its object is to provide means for preventing1 leakage of the contents of such vessels through the spout `or other outlet thereof when not in use.
The invention further consists in the improvements in construction and arrangements of parts, as will be fully described hereinafter and pointed out in the claims.
To these ends our improvements comprise, in brief, the formation of a valve-chamber intermediate the exit and the containing portion of an oil-can or the like, said chamber' being bounded inwardly by a diaphragm or closure having an orifice therethrough. A valvestem extends through said oriiice and has a head that is normally seated against said diaphragm or closure, closing the orifice therein from within the valve-chamber, while a helical spring surrounding said stem within the vessel exteriorly of said valve-chamber ex- .erts pressure between said diaphragm or closure and a yielding member that is located near 'the opposite end of the vessel, and to which the opposite end of the valve-stem is connected to normally tensionally hold said valve seated against the diaphragm or closure to close the orifice therein.
When ejecting oil from the vessel by the application of thumb-pressure directly applied to a flexible wall thereof, means are provided whereby such pressure is communicated to the helical spring aforesaid to compress same and to move the valve-stem to open the valve, the subsequent retraction 'of said spring serving to again close said valve.
In the drawings accompanying this application, Figure l is a vertical sectional view through an oil-can provided with our improvements. Fig. 2 is a top plan view of the flexible base of an oil-can, showing the tensional is capable of a wide application with fluid containing and ejecting vessels, we have for convenience illustrated its employment in conjunction with an oil-can such as is commonly employed for containing and applying lubricating-oil.
The drawings show an oil-can having a iiat base upon which it stands, with its spout disposed vertically. Were these oil-cans always placed upon their'base when not in use, there, would be no danger of leakage; but they are very often laid down sidewise with the spout Vinclined downwardly, when there is nothing to prevent the oil from flowing outwardly through the unobstructed spout. With our improvement such loss of oil is entirely obviated, as will be perceived from the following detailed description: v
A indicates a usual conical form of oil can or receptacle having the interiorly-threaded neck a and a spout B, having a threaded end screwed into said neck over a gasket or washer Disposed within the'neck portion a iS a transverse diaphragm or partition, as C, having a circular orifice c therethrough, forming, with the wall ofthe neck portion a, an isolated chamber for the passage of oil from the body of the receptacle to the spout. A valve-stem, as D, disposed vertically within receptacle A, is introduced through the orifice c and has an annular head or valve, as OZ,
that is adapted to be seated upon the upper surface of diaphragm C about the edge of oriiice c to close the latter. The lower end of stem D is secured to a strip of fiat spring metal, as E, that extends transversely across the receptacle A, near the iiexible base a thereof, said strip E being preferably provided with an intermediate depending curvature, as at e, which lies in close proximity to the base a', whereby when the base is pressed inwardly to expel the oil the stem D will be moved forwardly and will move its head away from the valve-seat, permitting egress of oil through the orifice c and thence through the spout B. A helical spring, as F, surrounds the stem D and abuts at its opposite ends, respectively, against the diaphragm C and strip E, being sufficiently contracted therebetween to exert tension necessary in firmly holding the valve CZ against its seat. rlhe strip E, as seen in the drawings, is secured at its opposite ends to the base a; but it may instead be secured against the lower side wall of the can, asis obvious.
Instead of the strip E we may employ a spider-frame, as E, (see Fig. 3,) composed of a central portion a, having' the radial arms c2, which may be three or more in number, to permit pressure directed against the portion e' through the medium of base a to be communicated in a true axial line to the stem I), whereby the operation of the valve is rendered more certain and effective. An important function pertaining to both the strip E and spider E is to relieve the base a' of a major part of the strain developed by the tension of the valve-closing spring F.
In Fig. 4 we have shown the oil-can as terminating' in a contracted exteriorly-threaded portion, as Gr, having a transverse closure g, provided with an orifice, which latter, as seen in Fig. 5, may be square, as at g, to receive a valve-stem It, that is circular in cross-section, or, as seen in Fig. 6, that is circular, as at g2, to receive a square valve-stem, as 71,. The valve-stem is headed with a valve, as h2, that is adapted to be seated against the outer surface of closure g to close the orifice therethrough. `I indicates a discharge nozzle or spout whose inner end is provided with an exterior thread, and J indicates a tubular union or coupling member having an interior thread. It will now be perfectly obvious that through the provision of the thread upon said union or coupling J the nozzle may be screwed thereto, and also the oil-can, by its contracted threaded portion G, may be screwed into the opposite end of said union or coupling. The advantage of this form of our invention is that it is economical to manufacture, as the can may be pressed out of sheet material or otherwise cheaply produced, and by means of the simple form of coupling indicated the members may be easily and quickly united, the coupling I also serving as the valve-chamber. By constructing the valve-stem of a section 'different from the orifice in the closure, as indicated, or otherwise, a passage is provided in said orifice past said stem, whereby the orifice serves as a contacting guide for the stem and also forms a passage for the iiuid contents of the oil-can when the valve if is removed from its seat. A helical spring, as t', surrounds the valve-stem I and exerts pressure between the closure g and the base of the oil-can to hold said valve normally seated to close the orifice in said closure.
Having now described our invention, we declare that what we claim is* 1. In an oil-can having a discharge-outlet and a thumb-operated fiexible base to eject its fiuid contents, a valve-passage anterior to said outlet, and a valve to close said passage, together with a valve-stem, a helical spring, an upper, rigid support therefor, and a lower, retractile support for said valve-stem and helical spring arranged to yield in the plane of movement of said fiexible base.
2. In an oil-can having a discharge-outlet and a thumb-operated fiexible base to eject its iiuid contents, the combination of a diaphragm anterior to said outlet, an orifice in said diaphragm, a valve to close said orifice, a valvestem, a helical spring surrounding said valvestem and bearing upwardly against said diaphragm, and a transverse, retractile support for the lower ends of both said valve-stem and helical spring, said support being arranged in the path of movement of the thumb-operated base, to communicate pressure therefrom to unseat said valve.
3. In a Huid-containing vessel having an integral interiorly-threade(l, contracted portion near its outlet, a discharge-nozzle fitted therein, a diaphragm integral with said vessel across the contracted portion thereof, forming a valve-chamber between said diaphragm and nozzle, said diaphragm having an orifice, a tensionally-seated valve normally closing said orifice, and pressure means to hold said valve unseated during egress of the Huid.
4. Inavessel having an integral interiorlythreaded, contracted portion provided with an outlet, and a wall capable of being iiexcd to eject fluid matter therefrom, an integral partition having a valve-orifice disposed interiorly of the vessel providing a valve-chamber intermediate said vessel and said outlet, a valve normally closing said passage, and means for automatically opening said passage with the flexing of said wall.
5.
