UNITED STATES JOHN J'. CATRON, OF BONHAM, TEXAS.

FLUID DISPENSER.

Application filed August 18, 1919.

To all whom t may concern.'

Be it known that I, JOHN J. CATRON, a. citizen of the United States, residing at Bonham, in the county of F annin and State of Texas, have invented certain new and useful Improvements in Fluid Dispensers, of which the following is a specification.

This invention relates to new and useful improvements in fluid dispensers.

The invention has to do particularly with improvements and additions relating to my Letters Patent No. 1,301,385, issued April 22, 1919.

One of the improved features is an automatic drain for the accumulating cylinder whereby said cylinder is drained when the dispenser is closed; and whereby the operating mechanism is unoperatable until the dispenser is again opened and the drain valve fully closed. Such an arrangement makes for safety as well as accuracy.

Another feature includes an accumulating cylinder to which the liquid is delivered under pressure after having been measured thru the meter; and from which cylinder the liquid is discharged by gravity thru an outlet valve. This arrangement obviates air pressure in the drain hose and makes for a smooth and rapid discharge.

One of the improvements over the aforesaid Letters Patent is the substitution of a hand valve for the foot operated air release valve, said hand valve being located close to the operating lever and making for greater convenience and simplicity. lIn this connection is also included a pressure relief valve, set to open at a given pressure and arranged so as to operate either when the controlling and air release valves are opened or closed.

Other features will be hereinafter more particularly brought out.

The invention will be more readily under stood from a reading of the following specification and by reference to the accom panying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is an elevation of a dispenser constructed in accordance with the invention,

Fig. 2 is a side elevation of the control-` ling ,and measuring mechanism,

Fig. 3 is a front elevation of the same,

Fig. 4 is a sectional detail of the liquid control valve,

Fig. 5 is a sectional detail of the air re lease valve,

Serial No. 318,339.

Fig. 6 is a sectional detail of the master air valve,

Fig. 7 is a detail of the liquid control valve, and

F ig. 8 is a detail of the air control valve.

In the drawings the numeral 1 designates aliquid discharge pipe and 2 a compressed air delivery pipe. These pipes are arranged to be connected with the gasoline discharge pipe and the air pressure pipe of a suitable storage tank, such as the storage tank shown in my co-pending application filed May 2, 1919, Serial No. 294,277, which has issued in Patent No. 1,352,788, or any other equivalent structure. The pipes 1 and 2 are connected to couplings 3 and 4 respectively. The couplings are connected by a hollow cross member 5 which, however, communicates only with the coupling 4. .A pipe 6 including a number of elbows extends upward in rear of the pipe 1 and is carried over and down in front thereof to a point of connection with the hollow cross member 5. This pipe provides a vent for the storage tank with which the dispenser is used; A normally open hand valve 7 is connected in the pipe 6 and includes a spring pressed valve plunger 8, which is shown in its de` pressed or closed position in Fig. 5.

A liquid control valve 9 is connected to the upper end of the coupling 3 and an air control valve 10 is mounted on the coupling 4. An air supply pipe 11 is bent at right angles and leads from a master air valve 12 to the valve 10. This master valve is shown in detail in Fig. 6. This valve has a spring pressed valve head 13 operated by a detent 14 which is engaged by the inner end of an arm 15 pivoted on the valve. The valve 9 has a tapered plug 16 with an opening 17 therethru; while the valve 10 has a tapered plug 18 provided with an air port 19 extending therethru and connecting with a triangular duct 20 in the surface of said valve. These valves are provided with an operating lever 22 mounted therebetween. The upper end of the lever engages the arm 15 of the master valve when the lever is swung to open the liquid and air valves as in said Letters Patent No. 1,301,385.

An elbow 23 leads from the top of the valve 9 to a suitable meter 24 from which a discharge pipe 25 leads to a T 26. A short pipe 27 connects the T 26 with an accumulatingrcylinder 28, preferably of glass. A discharge pipe 29 leads from one branch of llO (ill

the T 26 and has an ordinary globe valve 3() connected therein. An elbow 31 is connected to the end of the pipe 29 and a service Vhose 32 leads from the elbow; said hose hav ing a nozzle 33 `at its end. An air vent pipe 34 leads from the top of the elbow to the top of the cylinder.

In thel center of the cylinder an overiiow pipe,Y 35 isb arranged 'and has a section 36 leading down to an elbow 37 which is mounted on the upper end of ay section 37 leading back to the @orage tank. From the T 26 a second drain pipe 38 leads to the elbow 37. Anordinary rotary cutfoff valve 39 similar to the valve 9 is connected in the pipe 38 andy this valve is normally closed to prevent the'liquid from the cylinder draining back intothe pipe 37 A lever 40 is secured to the stem of the valve 39 and has its lower end pivoted to the upper end of a link 41 havingitslower end connected with an ear 42-proj ecting laterally from a vertically slidable rod 43, said rod being supported by the link, A cross-bar 45 is suitably fastened to ltheirmerside of the door 46 of the cabinet 7 inwhich themechanism is enclosed. The bar l45 is positioned so that the door 46 must beentirely lowered and the valve 39 entirely closed,to permit the handle lever 22 to pass said` bar. If the valve 39 remained partly open .liquid would flow back into the drain pipe37 when` it was being dispensed thus defrauding. the4 customer. Then the door is slid up. to close thecabinet the bar 45 engages the ear 42, and pushes the link 41 upwardly therebyswinging the valve lever 40 and opening the valve 39.

Asbeforestated the device is to beused in connection with, a suitable storage tank. 'I"l1e,master air valve 12 is connected with an ainsupply pipe 48; which receives compressed air from a suitable source and thru @pressure reducing valve 49.

In.,using the dispenser the operator depresses theplunger 8 of the valve 7 with one hand, and graspsthe handle lever 22 with the other.` hand. This closes the air vent or. exhaust. By swinging the lever 22 upwardsthe valve 9 is first openedL and when thelupper end of the lever engages the arm itlie ,master air valve12 is opened, whereby compressed air flows thru the pipe 11 and past the valve 10 and thru the pipe 2 toy thestoragetank. Liquid is forced out thru thepipe 1. The exact operation of these parts will be understood when considered in connection with the disclosure in the Letters Patent No. 1,301,385 before referred to. The liquid is forced by the compressed air thru elbow 23, pipe 25, T 26 and pipe 27 tothe accumulating cylinder 28. When a predetermined quantity of liquid has: passed the meter the handle 22 is swung down to cut-olf Athe supply of liquid and air and the operator releases the valve 7 whereby the air pressure below the valves 9 and 10 is vented. So long as the valve 7 is held closed by the operator the air in the cross-member 5 `and pipe 2, acts to elevate the liquid, but when the operator releases the valve, the air from the pipe 2 and member 5 passes out through the pipe 6.

The nozzle 33 having been placed in the receptacle to which the liquid is to be delivered, the operator opens the valve 30 whereby the liquid in the cylinder 28 flows by gravit-y down thru pipe 2 7, T 26, pipe 29, elbow 31, hose 32 and is discharged from the nozzle Itl will be seen that an absolutely safe dispenser is had. Theease and rapidity of operation is, apparent and the high degree oi' accuracy makes the dispenser eflicient;

`What I claim, is:
