FLUID-DISPENSING 1?.PPARATUS.

Application filed December 16, 1921.

T0 all w/iom it may concern.

Be it known that 1, JOHN J. CATRON, a citizen oi the United States, residing at Bonham, in the county of Fannin and State of Texas, have invented certain new and useful improvements in l luid-Dispensing Apparatus. of which the following is a specification.

This invention relates to new and useful improvements in "fluid dispensing apparatuses.

The object of the invention is to provide means tor automatically operating a drain valve for draining the measuring receptacle ot a visible dispenser, when the door oi said dispenser is fastened in its closed position; as well as for releasing said valve when the door is untastened.

A. further object is to provide a dispenser of the character described in which the parts are compactly. economically and conveniently arranged and their number reduced in a practical manner.

In carrying out the invention a drain pipe is extended from the measuring receptacle and connected with the overflow or other pipe which returns fluid to the underground tank. A self closing valve is connected in the drain pipe and located so that its stem is engaged by the fastening element or the dispenser door, the said valve being normally closed. Vhen the door is closed and its fastening element swung into its locking position the valve stem is depressed and the valve opened, whereby the receptacle is au tomatically drained.

A construction designed to carry out the invention will be herein'atter described together with other features of the invention.

The invention will be more readily understood from a reading of the following speciiication and by reference to the accompany ing drawings in which an example of the invention is shown and wherein:

Fig. 1 is an elevation of a dispenser CO11- structed in accordance with my invention,

Fig. 2 is an enlarged vertical sectional view of a portion of the dispenser,

Fig. is a similar view at right angles to Fig. 2,

Fig. 4 is a cross sectional view taken on the line 4l4-. of Fig. 1,

Fig. 5 is a cross sectional view taken on the line 5-5 of Fig. 1,

Fig. 6 is a cross sectional view taken on the line 6-6 of Fig. 3, and

Serial no. 522,897.

Fig. 7 is a sectional detail of the drain valve.

in the drawings the numeral 10 designates a cylindrical cabinet having a base :tiange ll. a doorway 12 and a door 13 mounted to slide vertically in the doorway. A. hasp 1%- is hinged to the upper outer side of the door and is adapted to engage an eye 15 mounted on the cabinet immediately over the doorway.

A base plate 16 is mounted on top of the cabinet and has an annular flange overhang ing the same. A transparent cylinder 1? preferably of glass is mounted on the plate within the flange and may be surrounded by an open mesh guard 18. A cap or dome 19- is mounted on top of the cylinder and is tastened by vertical rods 20 having their lower ends secured in the base plate, whereby the cylinder is held in place. Suitable fluidtight joints (not shown) are provided at each end of the cylinder, which with the base and cap form a visible measuring receptacle. An electric lamp globe 21 may be mounted on top oi": the cap.

The base plate 16 is preferably cast with a depending boss 22 having a passage 28 ex.- tending from the centerto rear side of said plate. An overflow tube or column 24: is mounted centrally of the cylinder 17 and has its lower end screwed into the plate in registration with the passage his tube is fixed against movement and has its upper end terminating below the upper end of the cylinder, whereby fluid delivered to the cylinder will overflow into the tube at a predetermined level, thus assuring an accurate measure which cannot vary. '1 1e cylinder may be subdivided within the length of the tube by placing on said cylinder graduation marks at the proper elevations to measure the difierent units into which the measure is divided. 4

A return or ove'rilmv pipe 25 has its upper end screw threaded into the rear of the boss 22 so as to connect with the passage 2 This pipe is suitably connected with the urderground or storage tank which contains the fluid which is dispensed by the device. A supply pipe 26 extends upwardly within the cabinet at one side thereof and the liquid may be elevated in said pipe in any suitable manner by means which is not considered necessary to illustrate. This pipe is connected with a T 27. A pipe 28 extends Cal from the T 27 and is extended upwardly at right angles so as to enter the bottom of the plate 16. The gasoline or other liquid supplied thru the pipe 26 passes thru the T 27 and by way of the pipe 28 into the measuring receptacle. When the measuring receptacle is closed the gasoline will overflow at the top of the tube 2 1 so that an accurate measure will be had.

A drain pipe 29 extends downwardly from the plate 16 and is turned at right angles so as to connect with a drain valve 30, which is illustrated in detail in Fig. 7. The valve comprises a spring pressed valve 31 normally closing on a seat 32. A plunger pin 33 is mounted in the valve so as to engage the stem thereof and to project forwardly from the valve casing. hen the pin is pressed inwardly the valve is unseated and opened. Normally the valve is closed so as to prevent the passage of liquid therethru. A pipe 34: leads from the valve and extends rearwardly as is best shown in Fig. 6. This pipe is bent at right angles and connected with the overflow pipe 25. It will be seen that when the valve 30 is opened the liquid from the measuring receptacle will pass down thru the pipe 29, thru said valve and by way of the pipe 3 1 into the overflow pipe 25, whereby the receptacle will be drained. Before the receptacle can be filled the valve 30 must be closed.

The mechanism for elevating the liquid thru the pipe 26 is, of course, mounted in the cabinet 10 and is accessible thru the doorway 12. When the door 13 is closed said mechanism is not accessible and liquid can not be elevated in the pipe 26. In order to automatically drain the receptacle when the door 18 is fastened I provide a stud 85 on the rear of the hasp 14- and locate the same so that it will pass thru an aperture 36 in the cabinet immediately above the doorway. The plunger pin 33 is located so as to register with the aperture and to project into the path of the stud 35. Thus when the hasp is swung upwardly to engage the eye 15, the stud will penetrate the aperture and engage the pin 33 so as to force the same inwardly, whereby the valve 81 will be displaced from its seat 32 and the valve opened. By this arrangement any gasoline or liquid remaining in the cylinder 17 will be drained thru the pipes 29 and 34, and conducted into the overflow pipe 25. This is a safety feature makes it impossible to fasten the door without automatically draining the visible measuring receptacle.

When the hasp is swung away from the eye 15, the pin 33 will be released so that the valve 31 may automatically close and thus when the cylinder 17 is filled the gasoline will fill the pipe 29, but cannot pass the valve 30 which will be closed. It is, of course, impossible to obtain access to the controlling means for elevating the gasoline until the door 12 is opened. The T 27 has connection with a dispensing valve 37 which may be' of any suitable type, and is provided with an actuating lever 38. A hose 39 is connected with the valve by means of a coupling 40, and this hose is equipped with the usual nozzle, not shown. When the hose is not in use it may be inserted within the cabinet and thus enclosed when the door is shut.

I connect a vent tube 41 to the coupling below the dispensing valve 37 and extend this tube upwardly so that it enters the cap 19 above the over-flow level of the liquid. The purpose of this vent tube is to prevent an airlock in the hose 39 and to provide a free passage of air so that the dis pensing operation may be efficiently carried out. This vent device is fully described in my Letters Patent No. 1,391,245, issued September 20, 1921.

Various changes in the dimensions and shape of the various parts as well as modifications may be made without departing from the scope of the appended claim. It is obvious that a device of this character permits of alterations and the substitutions of different parts as for instance the dispensing valve 37, the type of drain valve 30 and the specific connection of the supply and drain pipes.

What I claim, is:

In a fluid dispenser, the combination of a cabinet, a liquid measuring receptacle carried by the cabinet, means for supplying a liquid to the receptacle, means for dispensing liquid from the receptacle, a drain pipe extending from the receptacle, an overflow pipe connected with the receptacle and having connection with the drain pipe below the receptacle, a normally closed drain valve interposed in the drain pipe and having a pro jecting operating element, a vertically sliding door mounted in the cabinet, the drain valve being located above the doorway of the door, and a hasp mounted 011 the upper end of the door and engaging the valve cu erating element to open the valve when the door is elevated and fastened.

In testimony whereof I afliix my signature.-

JOHN J. CATRON.
