LIQUID-DISPENSING APPARATUS.

Original No. 1,309,505, dated July 8, 1819, Serial No. 293,103, filed April 28, 1919.

filed l'ctober S, 1920.

To all whom it may concern:

Be it known that I, MERRILL A. Bnacier a citizen of the United States, residing at Penn Yan, in the county of Yates and State of New York, have invented new and useful Improvements in Liquid-Dispensing Apparatus, of which the following is a specification.

This invention relates to liquid dispensing apparatus and more particularly to inr proved device for the purpose of dispensing gasolene in garages, public service stations and at other points at which automobilists may stop to secure quantities of gasolene.

One of the objects of the invention is to provide an improved apparatus which will automatically dispense predetermined quantities of the gasolene.

A further object of the invention is to provide an apparatus which may be employed to forcibly eject the gasolene from the source of supply and which will employ electrical apparatus to control the quantity of gasolene dispensed.

The above and additional objects are accomplished by such means as are illustrated in the preferred embodiment and accompanying drawings, wherein like characters of reference denote like or corresponding parts throughout the several views, in which Figure 1 is a side view of the apparatus constructed in accordance with my invention, showing the same partially diagrammatlcally, parts being broken away to more clearly indicate the construction.

Figure 2 is a section taken approximately on the line 2-2 of Figure 1.-

Referring to the drawing, wherein is illustrated the preferred form of my invention, in which like numerals of reference indicate like or corresponding parts throughout the several views a supply tank 1 is buried-in Specification of Rcissued Letters Fatent.

mounted at intervals in the pipe 4 and has a weight 6 attached to its free end, the weight being disposed so as to be suspended by the cable from one of the pulleys 5 which is held in an elevated position. This weight 6 is light in comparison with the weight of the float 2 and is merely heavy enough to maintain the cable or flexible element 3 under aroper tension. A scale 7 attached to one of the pipes is graduated and provided with numerals and the cable carries a pointer 8 which indicates the graduations on the scale as the float 2 varies in position with the changing level of gasolene in the storage tank 1. An air vent pipe 9 is at tached to the storage tank and projects considerably above the ground level to supply air to the tank.

A supply pipe 10 has one end submerged in the gasolene in the storage tank and its opposite end connected to a pump 11 which is operated by a belt 12 driven from a motor 13 which motor is connected by a conductor 1 to a suitable point. From the opposite side of the pump 11 the supply pipe 16 eX- tends to the auxiliary supply receptacle indicated generally at 17. This receptacle is mounted upon a standard 18 and comprises the container 19 adapted to contain a relatively large quantity of gasolene and which "nay be supplied with a glass panel 20 if so desired. This receptacle is also provided with a float 21 connected by a flexible cable 22 to a small weight 23; this cable 22 passes over pulleys 2% arranged in a system of piping 25 which leads from the interior of the receptacle 19 to a register board or panel 26. This board or panel is disposed so that the cable 22 passes over its base longitudinally as shown to advantage in Figure 1 and this board has its face raduated to indicate 5 the gallons and half gallons as shown. Ob viously the board maybe of any desired length and the graduations may be carried out as far as is desired. A plurality of openings 27 are provided in the board at the graduation which indicates each gallon, and each opening is provided on its interior with spaced apart contact members 28 as in Fig; ure 2. These members 28 have their en exposed on the back of the board and are connected in series through a conductor 29 leading to the source of current 15 and by another conductor 30 leading to the motor 13. A removable rotatable plug 31 is adapted to be inserted in any of the openings and this plug is provided on its outer end with an arm 32 which is disposed at right angles to the longitudinal edge of the board when the plug is in operative position as in dicated in Figure 1. The inner end of the plug 31 has oppositely projecting fingers 33 which are adapted to engage the contact 28 in order that the circuit'will be completed. Obviously a turning movement of the plug will cause the finger 33 to disengage the contact members 28 and consequently break the circuit. The flexible cable or cord 22 is pro vided with a pointer or indicator 35 which moves with the cable across the board 26 as the float 22 varies or changes its position in the receptacle 19. This indicator 35 is adapted to engage the arm 32 of the rotatable plug so that the same will be turned for breaking the circuit.

Assuming-that a person desires to secure a quantity of gasolene, the plug will be insorted in the opening having the numeral corresponding to the number of gallons desired. In Figure 1 the plug is illustrated as being disposed in the opening for two gallons. This insertion or" the plug with the arm 32 extending transversely with respect to the board 26 completes the circuit and starts the motor 13 whereupon the pump 1.1 is actuated for pumping the gasolene trom the storage tank to the auxiliary supply tank 19 through the pipes 10 and 16. As the gasolene enters the receptacle 19 the that 21 rises therein and exerts a pull on the cable 22 thus causing the indicator 35 to move across theboard until one end of the indicator engages the arm 32 and turns or rotates the rotatable plug 31, causing the tingers 33 of the plug to disengage the contact members and thereby breaking the circuit whereupon the pump immediately stops. No more gasolene can be secured until the plug is again inserted in the opening for causing .the circuit to be closed across the contact member 28.

The foregoing description and accompanying drawings have reference to what might be considered to be the approved or preferred form of my invention. I desire it to be understood that I may make such changes in the construction, combination and arrangement of parts, materials, dimen sions, et cetera, as may prove expedient and fall within the scope of the appended claims.
