SLQW-FEED CAN.

Specification of Letters Patent.

Patented Dec. 29, 1914.

Application filed September 17, 1913. Serial No. 790,222.

To all to]: am it may concern Be it known that I, WILLIAM H. MoNU'r'r, a citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Slow-Feed Cans, of which the following is a specification.

This invention relates to the closures of receptacles or containers of the type known as printers cans, that are used for holding a cleaning fluid such as benzin or gasolene; and which devices are inverted for the purpose of discharging a small quantity of the fluid on the desired object, or at the required place; and which are also frequently em ployed by tailors and others for cleaning garments; or in fact, by persons generally when it is desired to discharge a small quantity of such fluids upon various objects or places.

The principal object of the invention is to provide in a device of this character, a form of valved member closing the outlet of the bushing, which is so constructed that when the can is inverted and the bushing merely pressed against the object, the valve will open a very slight extent and discharge a small quantity of the gasolene or other fluid: but immediately upon the can being withdrawn from contact with the article, the valve will automatically close and prevent further discharge of the fluid, even in the inverted position of the can.

A further object of the invention is to provide in conjunction with the device as set forth, an arrangement whereby the valve and seat are located at the extreme upper end portion of the bushing or outlet, and in which the fluid, when the can is returned to normal position after having been inverted, can all pass down from the bushing into the body of the can; whereby it follows that there will be practically none of the fluid whatever exposed above the valve and seat, subject to evaporation. D

Another object of the invention is to provide an improved arrangement of the several parts, whereby the usual finely apertured disk at the lower end of the bushing is rigidly secured in position by the simple operation of turning or inn ng over a thin flange; which disk will orm a support for the coil spring that serves to hold the valve seated.

In the accompanying drawing illustrating one embodiment of my invention, Figure l Isa vertical section through a can equipped with the said invention. Fig. 2 shows the bushing member detached and before having the disk secured thereto; and Fig. 3 is a lower end view of the bushing and parts as shown in Fig. 1.

In the drawing I show the device applied to a can 5 of the form usually employed by printers and others; the can having an opening at the top in which is secured by suitable means a bushing (i. This bushing is somewhat elongated, and at its upper or outer end it is made tapering, and of globular configuration, having a small opening 7 at said end.

At the lower or inner end of the bushing 6 is arranged a disk 8 of sheet metal provided with minute flame-proof apertures, which disk is strongly secured in this position and has an opening 9 at its center. I preferably secure this disk in position by providing an annular extension 10 on the lower end of the bushing 6 forming a shoulder 12 above the extension in the bore of the bushing, and after inserting the disk thatsnugly fits in this extension against the shoulder, I bend or spin the thin extension inwardly around the margin of the disk, as shown in Fig. 1, so as to very strongly secure the disk in this position. A rod 13 is inserted in the opening 7 at the top of the bushing, into and through the bushing and through the opening 9 in the disk 8, having a snug fit in the latter opening, but being somewhat free in the opening 7, or oll'sot from the wall thereof in order to permit outflow of the fluid from the bushing when the can is inverted. ()n this rod 13 is socurcd a valve 14 of rounded or globular form, for the purpose of engaging the inner globular portion or bore of the bushing surrounding the opening 7. A coil spring 15 isplaced on the rod 13 engaging the disk 8 at one end and being compressed thereby, so as to cause the valve 14 that is engaged by its opposite end to be forced upward and seated on the bore of the bushing around the opening 7, to thereby close the outlet of the bushing. ln the norn'ial closed position of the valve 14, the rod 13 to which the valve is rigidly secured hasits outer extremity 16 projecting a short distance beyond the top or end portion of the bushing (3, whereby lbi) when this projecting portion of the rod is brought to engage an object and the rod is depressed to bring its end flush with the end of the bushing, the valve 14 will be moved inwardly from its seat a comparatively short distance, and thus provide a comparatively small or constricted outlet for the fluid in the can.

In the use of the device the can is merely grasped by the operator and inverted with the projecting valve rod pressed against the article or place upon-which it is desired to discharge a small quantity of the fluid, and it will be readily understood that the valve will be retracted a small distance from its seat, permitting the fluid to flow out by gravity; but immediately upon the can being lifted or withdrawn from the object, the coil spring will close the valve and prevent any further outflow of the fluid in the can. Upon now restoring the can to its normal or upright position, it will be seen from Fig. 1 that the valve is pressed against the extreme upper portion of the bushing, so that practically none of the fluid whatever is retained above the valve and thereby exposed to evaporation; while the fluid that passed I down into the bushing during the inversion of the can can now flow down through the apertured disk 8 and be returned to the body of the can.

The bushing 6 is shown as provided with an external flange 17, below which the bushing is threaded at 18, for the purpose of screwing the bushing into a ring or sput 19 in the can.

Having thus described my invention, what I claim is: Y

A. can closure comprising an elongated bushing having its upper end tapering spherically to an opening, and its lower end externally flanged and screw threaded below the flange to screw into a threaded opening in a can, the latter end of the bushing having a comparatively thin extension with a shoulder inside of the extension, a disk of finely perforated sheet metal resting on said shoulder with said extension bent around the margin of the disk to secure it in such position, said disk having a central opening, a valve rod slidable through the openings in said bushing and disk and ofi'set from the bushing at the opening to permit outflow of the fluid through the same, a globular valve fast on said rod, and a coil spring on the rod engaging the said disk at one end and having its other end pressing the valve against the bushing to normally'close the outlet from the bushing, the rod in the closed position of the valve projecting a short. distance from the bushing whereby its depression flush with the bushing will cause said valve to open.
