DRUGGISTS DISPENSING OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 732,620, dated June 30, 1903.

Application filed August 13, 1902. Serial No. 119,557. (No modela f To a/ZZ whom it' may concern.:

v Be it known that I, J osEPH A. DINKLER, a citizen of the United States, residing at Anadarko, in the county of Caddo and Territory of Oklahoma, have invented new and useful Improvements in Druggists Dispensing Oil- Cans, of which the following is a specification.

My invention has relation to new and useful improvements in dispensing vessels, and particularly to that type or kind wherein the fiow of the-liquid contents from the vessel is assisted or augmented by means of air forced within the vessel by means of asuitable pump and compressed upon'the surface of the liquid.

The object of the invention is to provide an improved vent which will be normally open to permit the egress of air and which will be so associated with the faucet or outlet of the vessel as to be closed while the liquid is being drawn, thus allowing the full force of the compressed air to be exerted upon the liquid, and which will be opened by the-closing of the faucet, whereby the compressed air remaining in the vessel will be permitted to escape. f

A further object is to so connect the vvent device With the faucet that upon the closing of the faucet the excess of compressed air in the reservoir will be exhausted through the faucet-spout and blow out the liquid which may adhere thereto after the flowhas been stopped, thus keeping the interior of said spout clear of deposits, which may become objectionable.

The invention is designed to be used especially in connection with dispensing vessels where the contents of said vessels consist of heavy liquids, such as oils, which How slowly, and is particularly useful when the contents have become congealed or thickened by changes of temperature and the iow by gravity thereby retarded or rendered uncertain.

I have fully and clearly illustrated my invention in the accompanying drawings,where 1n- Figure 1 is a vertical central sectional view of a vessel having my improved vent attached thereto. Fig. 2 is a logitudinal sectional View of the preferred form of faucet in connection with which the vent is operated and showing the faucet closed and the vent open.

Eig. e

isa longitudinal section of a slightly-modified form of faucet and vent, the faucet being shown open and the vent closed. Fig. 4 is a `view similar to Fig. 3, but therein the faucet lindrical in form and may be of such capacity 6o as may be desired or required. Atits lower portion this vessel is provided with an annular supporting-flange 2, of suiicient height to support the bottom of the vessel well above the surface upon which it rests, thus preventing the oil or other contents from becoming unduly affected by the temperature of the said surface. vessel is provided with a suitable handle 3, by which it may be lifted and conveyed from place to place as desired. In the top of the vessel is provided an air-inlet 4,which opens into the interior thereof and is provided with a vertical annular flange 5, having exterior screwthreads, substantially as shown in the draw. ings. Upon the flange 5 is secured a cap 6, formed with a central vertical nipple 7, over which is seated and held the neck of a bulb- Upon its top portion the pump 8, which is of a Well-known construction and is provided with the usual checkvalves (not shown) to control the inlet and outlet of the air. By means of this' bulbpump air is forced into the interior of the vessel and compressed upon the surface of the contents,which are ejected with increased force from the faucet when it is opened.

9 designates the faucet through which the contents of the vessel are drawn. This faucet consists of a body portion or shell 10, provided with the usual duct or channel 11, which communicates with the interior of the vessel. At its rear portion this shell is provided With a nipple 12, which ts snugly within an aperture in the wall of the vessel. The faucet-shell is also provided at a point adjacent the nipple 12 with an annular flange 13, arranged to abut against the vessel and by means of which it may be fastened in position. At a suitable point the faucet-shellis provided with-a vertical transverse valve-seat 14, which is circular in cross-section and the walls of which taper from top to bottom, substantially as shown in the drawings. Within this valve-seat is rotatably arranged a turn- IOO plug 15, the upper end of which is provided with a handle 16, by which the plug is rotated. Through the turn plug extends a transverse opening 17, which is adapted to register with the duct in the faucet-shell to permit the outflow of the liquid in the vessel. This turn-plug is also formed upon its front portion-that is, the portion which is in front when the faucet is closed-with a recess or by-pass 18, the purpose of which will be hereinafter set forth.

Suitably secured within the wall of the vessel 1 and opening into the interior thereof is a pipe 19, which pipe is arranged upon the exterior of the vessel and extends downwardly from its connection therewith to a point adjacent the front of the faucet, where it is bent at the proper angle, as at 20, and inserted in a channel 21, formed in the faucet-shell and which communicates with the by-pass 18 in the turn-plug when the plug is turned to close the faucet.

In Figs. 3 and 4 of the drawings I have shown a slightly-modified form of the invention,wherein the pipe 19 is carried in a straight line down the face of the can and inserted in a channel 22, formed in the faucet-shell in rear of the turn-plug, substantially as shown. Instead of providing the turn-plug with a bypass, as shown in Fig. 2, it is formed with a transverse aperture 23, which is so disposed as to register with the channel 22 when the faucet is closed, and thus provide the receptacle with an outlet for the compressed air and to close the vent when the iow through the faucet is cut off.

The operation of the device is as follows: When it is desired to withdraw the contents of the can, the turn-plug is rotated to provide a continuous duct through the faucet. By

opening the faucet it will be observed the bypass 18 is thrown ont of register with the channel 21, formed in the faucet-shell, and the escape of air from the can be prevented. Air is then pumped into the can .by means of the bulb-pump, and pressure being thereby eX- erted upon the surface of the liquid it will be forced from the faucet. When the desired amount is drawn, the faucet is closed, thereby placingr the by-pass in register with the vent-pipe and permitting the excess of air in the can to escape.

It will be seen that by means of the device above described the oil or other liquid may be readily and' rapidly forced from the can even after it has become too thick to flow freely by gravity. Itwill also he perceived that byeX- hausting the compressed air through the faucet all liquid which remains therein will be blown out and the danger of the spout becoming uncleanly or clogged by dust or other particles which may adhere thereto be obviated.

In a device of the class set forth, the combination with a receptacle, of an air-pump attached to the top thereof and exteriorly accessible, a faucet secured to the bottom of the receptacle and having a channel therein, a turn-plug in the faucet havinga by-pass which communicates with the said channel and the interior of the faucet when the plug is closed, and an eXteriorly-located pipe connected at its opposite terminals to the channel and the upper portion of the receptacle whereby the air under pressure in the receptacle Will be permitted to escape through the discharge faucet upon stopping the liow of the liquid.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH A. DINKLER.
