WILLIAM J. WYATT AND CLAUDE 0'. REED, Q11 MANSFIELD, ARKANSAS-.

LIQUID-VEN=DING MACHINE.

Application; filed. February 10, 1923. Serial No. 618,275. i

T0 (6 whom it 17mg concern-i Be it known that we, TI'LLIA'M J. lVYA'rr and CLAUDE 0-. REED, citizens of the United States, residing at Mansfield, in the county of Sebastian and State of Arkansas, have invented certain new and useful Improvements in Liquid Vending Machines; and we do hereby declare the following to be a full, clear, and exact description of the in vention, such as enable others skilled in the art to which it appertains to make and use the same. 1

The invention l las relation to a machine for dispensing a liquid, such as gasoline, toilet water, perfume and other liquids, the dispensing mechanism being released by depositing a coin of predetermined value, and the dispensing. mechanism beingactuated by movement of a plunger.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

WVhile the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing fromthe nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is a vertical longitudinal section of a vending machine of the character aforesaid embodying the invention,

Figure 2 is a horizontal section on the line 2-2 of Figure 1,

Figure 3 is a transverse section on the line of Figure 2,

Figure 1 is a transverse section 011 the line 14 of Figure 2,

Figure 5 is a detail view, and

Figure 6 is a. detail sectional view taken on the plane indicated by the line 6-6 of Figure 8. v

Corresponding and like parts are referred to in the following description and desig nated in the several views of the drawings by like reference characters.

The numeral 1 designates a suitable cabinet for receiving the working parts. Associated with the cabinet 1 is a container 2 for holding the perfume or other liquid to be dispensed. The dispensing tube 3 is of rubber and connects with the bottom of the nta ner 2- A ever t c nt l t 11 w of the liquid through the dispensing tube 3 and is pivoted at one end and has a spring 5 in cooperative relation therewith i whereby to yieldiinigly holfd the lever 4 in a given position to cut off the flow of'liqni-di A bar 6 coacts-with the lever 4 and limits the downward movement thereof. Thebar 64oz:- tends across the cabinet as shown most clearly in Figures 2 and 3. Two valves, A and B, are interposed in the length of. the tube'3 and their handles areuconnectedi by a link U for simultaneous movement to control the delivery of the liquid. The: link G connectswith the lever 4:. to be-operated thereby. A trip bar 7 pivoted at one end to the bar 6, has itsopposite end extending across the path of the lever 4: whereby upward-movement of the trip bar effects a corresponding movement of the lever 4 where bv to operate the valves A and B to permit delivery of the liquid to: be dispensed. A

push bar 8' is provided with a cam 9 which is adapted to operate the trip: bar 7 and lever 4, whereby to actuate thevalve mechanism and release the amount of liquidv tobe discharged. The push. bar 8 is spring'actuated and is normally urged forwardly by means Offi a spring 10 Bearward movement of. the pushbar 8. is

normally prevented by means of a lock bar 11 which engages a notch 8 providedflin a side of. the push bar. The lock bar, 11 is pivoted intermediate its ends, as shown at 11, and is adapted to be tripped by a coin D of determinate value depositedin a coin way 12, across which an end of the lock bar 11 extends to be engaged by the coin. when deposited in the machine. A stop bar 13 pivoted at 13 limits the upward movement of the lock bar 11 when actuated by the coin D deposited in the machine, whereby the coin is held in the coin way until the push bar 8 is pressed inward to effect a delivery of the liquid to be dispensed. A cord or flexible connection 14: is connected at one end to the stop bar 13 and at its opposite end to the push bar 8 and passes over a guide 15 intermediate its ends. When the pushbar 8 is moved inward, the cord or flexible connection. 14 is drawn upon to lift the stop bar 13, whereby to permit of a movement of the lock bar 11 under the weight of the coin D to release the coin which drops from the coin way into the bottom ofthe cabinet. As the push r 8 mo es inward, the l er t r e 19 the cam 9 and operates the valves A and B with the result that the liquid to be dispensed is delivered. On the outstroke of the push bar 8, the parts assume a. normal position to be again actuated when depositing another coin into the machine.

In use, with the parts in closed position as shown in the drawings and the tube 3 properly applied, a coin is dropped in the Way 12 which contacts with the lock bar 11, tilting it as suggested by the dotted lines in Figure 4, to the limited extent permitted by the stop bar 13 so that it will move out of the notch of the push bar or operating member 8 but still retain the coin. The push bar or operating member 8 is then pushed inwardly which causes the element 14 to raise the stop bar 14: so that lock bar 11 may further swing and the coin be completely released, and so that the cam 9 will engage and) elevate the trip bar 7 at its distal end which accordingly elevates the control lever or element 4: at its distal end which shifts link 0 in order to actuate the valves A and B to release the appropriate quantity of liquid. During such movement, the springs 10 and 5 are tensioned and hence when the push bar or operating member 8 is released, suchl springs react to restore the parts to normal position preparatory to the next operation. It will be noted that one of the valves is open while the other valve is closed which enables measuring of the quantity to be dispensed for the coin to be controlled and uniform.

What is claimed is:

1. A machine of the class described having a dispensing means, a control lever operatively associated therewith, an operating member, a pivoted lock bar for said member having an initial movement through deposit of the coin to release said member while retaining the coin, a stop bar to limit said initial movement, a pivoted trip bar overlapped by said control lever, means operable through movement of said operating member to shift the trip bar so that it will shift the control lever to actuate the dispensing means, and an operative con-- nection between said operating member and said stop bar to displace the latter to permit further movement of the lock bar to release the coin.

2. A machine of the class described having a dispensing means, a control lever operatively associated therewith, an operating member, a pivoted lock bar for said member having an intial movement through deposit of a coin to release said member while retaining the coin, a stop bar to limit said initial movement, a pivoted trip bar overlapped by said control lever, a cannon said operating member adapted to engage said trip bar to lift it and the control lever aforesaid, and a flexible member connecting the operating member and the stop bar to actuate said stop bar to permit further movement of the lock bar and the releaseof the coin.

In testimony whereof we afiiX our signatures in presence of two witnesses.
