COIN-CONTROLLED LIQUID DISPENSER.
Application fi1ed June 2, 1921. Serial No. 474,362.
To all whom it may concern: 2
Be it known that I, EDWIN F. KRoss, a. citizen of the United States, and resident of Horicon, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Coin-Controlled Liquid Dispensers; and I do hereby declare that the following is a full, clear, and exact description thereof. 1
My invention relates to new and useful improvements in a coin controlled liquid dispenser, and is more especially adapted for use in connection with an oil' and gasoline station for supplying the automobile trade. It is the general object of my invention to provide a dispensing device which is entirely controlled by a coin inserted therein so that the constant presence of an attendant will be unnecessary. i
It is a more specific object of the invention to provide a measuring pump which upon the insertion of a coin may be operated to dispense a predetermined amount ofgasoline or oil.
It is a further object of the invention to provide a double acting or a double cylinder pump which may be operated successively in opposite directions bythe insertion of successive coins.
With the above and other objects in view, my invention consists in certain structural details which will be fully described in connection with the accompanying drawings, in whichv Figure 1 is a front elevation of the device with a portion of the housing broken away to show the-interior thereof.
Figure 2 is a vertical transverse sectional View onthe line 22 of Figure 1, and
Figure 3 is a detail sectional view on the line 83 of Figure 2. i
Referring now to the drawings. 'by reference characters, the numeral 1- designates a suitable sup-port on which is mounted a housing 2 which contains one ormore pumps 3. Each pump, as shown in Figure 2, comprises two oppositelydisposed aligned cylinders 4: and 5 'which are connected by a pipe line 6 to the supply tank 7 which may contain oil, gasoline or the like. The liqu'id'to be dispensed is drawn in through the pipe line 6 into one of the cylinders and expelled through the pipe line'8, which is connected with the usual hose line, the end of which is supported by the hook 10 when not in use. Cooperating with the cylinders are the p1s- Yent instance for this purpose.
tons 11 which are mounted on the ends of a rod 12, which is provided with the usual packing" glands 13. The liquid is drawn into the cylinder through the port 14 which is controlled by a check valve15 and its cooperating spring 16. It is expelled through the outlet port 17, past the check valve 18 which is controlled by the spring 19.
' For the purpose of operating the pump, ll
h ave in the present instance, provided a reciprocating bar which is mounted in the aligned bearings 21 and 22 and connected' with the piston rod 12 by the cross arm 23. This bar may be reciprocated by any suitable means, a handle 24: being shown in the presis normally held against movement in either directionby the pa-wls 25 which are held by the coil springs 26 in engagement with the ratchet teeth 27 on the sides of the bar. In connection with each pawl, I have provided an electromagnet 28 which when energized will retract the pawl in opposition to the spring 26. The electromagnets are connected in parallel to the source of electric energy 29 and the circuit through the mag- The bar 20 net is completed by connecting the terminals 30 or 31 respectively. These terminals are in the form of spring arms which are so arranged as to be connected by a coin 32, in-
troduced through the slot 33'. 'A coin insertedv in the slot '33 passes downwardly through the chute 84; and is directed-by the switch 35 into one of the branches 36 or37 to the corresponding terminal. The switch 35 is provided withspurs 38 so that each to throw the switch so thatthenext coin will be directed into the other branch of the chute. I
"When the coin has been inserted and the bar approaches, the limit of its movement in.
.coin as it passes engages one of the spurs this direction, passes through the slot 40 and engages the coin 32,-forcing it out-past sition until the next coin. closes the circuit through the other magnet, permitting the bar "to be moved in the opposite direction.
' the ends of the terminal arms and interrupt- 'opposedj-n ieasuringcylinders, a piston recip rocable therein, locking means normally rendering said locking means again opera-- The housing 2 may be provided with as many pumps as may be desired. In'the present instance, in addition to pump which is controlled through the slot 33 by a 50 coin, I have shown a slot 41 for dispensing 25 worth of. gasoline, the pump which is controlled by this slot being actuated by the handle 43. I have also shown a slot 42 which controls a pump actuated'by the handle 44 for dispenslng oil. For the purpose of adjusting the amount of liquid which may be dispensed in accordance with'the prevailing market price, I have provided the end of the piston rod 12 with threads 45 and a lock nut 46 so that the capacity of the pump may be varied by adjusting the position of the pis-,
ton head 11. 1
From the foregoing description,- it will be seen that I have provided a co nv enient and practical device by which oil or gasoline or other liquids may, be automatically dispensed. Thus the automobilist mayobtain his supply at any time ofthe day or night and it will be unnecessary to maintain an attendant to care for the same.
I claim as my invention:
