LIQUID-VENDING CHINE.

Application filed November 25, 1921. Serial No. 517,448.

able others skilled in the art to vhich it ap pertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part-of this specification.

This invention relates to liquid dispensing mechanism and it is particularly adapt- -ed for dispensing gasoline and the like, the primary object being to provide means whereby the dispensing apparatus will become efiective upon the introduction of a check, coin or token of appropriate denominationinto the machine.

The mechanism is such that it operates as a coin-controlled mechanism although the coin control chute and its complementary parts so far as the present! invention is concerned is not an important feature.

The specific construction of the device selected for illustration will be apparent by reference to the following description in connection with the accompanying drawings,'in which Fig. 1 is a perspective view of a dispensing apparatus constructed in accordance with my invention, parts being broken away to show the interior construction thereof. Fig.2 is a vertical, longitudinal, sectional view through the base casing, one of the dispensing tanks, the pump or supplying it, dand means for controlling the pump,

3 'is a detailview of the float-actuated, contact-carrying stem. I

The hollow base 1 supports a dispensing reservoir 2, adapted to be supplied with the liquid from a suitable source, (notshown). The source may consist 'of a tank or reser voir embedded in the ground'and adapted to communicate with an intake pipe 3, communicating with a pump 4, discharging through a pipej5 into the top of the reservoir 2. The impeller for the pump 4 may be connected to the drive shaft of a motor 6 supplied with current from a main service line consisting of the

conductors

7 and 8, 5 which is tapped in a switch box 9 connected to the motor through the conductors 10 and 11. The switch box is provided with a reversing switch, as will be well understood,

and it is adapted to be operated by a circuit I energized by certain contacts in response to a float within the reservoir 2. For example, on the stem 12 projecting through the stufling box 13 in the top of the reservoir 2 and within the contact casing 14 is a float 15, movable in response to variations of the oil level within the reservoir 2. Thefioat stem carries one contact 16, which is adjustable and adapted to be received in the notched portions 17 18 and 19 so that it will operate at various levels of oil in the reservoir 2.

The switch controlling-circuit consists of a conductor 20 in series with a battery '21. One end of the conductor is connected to the switch box 9 and the other end to the live contact 16. At the upper end of the casing 14 is a contact 22 connected to a conductor 23, also connected to'the switch box so' that when the" live contact 16 abuts 8 against contact 22, the switch will be operated to cut out the-circuit for the motor 6. When the live contact 16 rests on the lower contact 24, connected to the conductor 25 leading into the box 9, the motor will be en- 8 er ized.

hen the motor is energized, it will operate the pump-4 and pump oil into the reservoir until the level reaches the point at which the contact 16 is set, at which time. the contact 16 will contact with the contact 22, reversing the switch so as to break the circuit and causin the pump to stop.

The oil or liquid wi remain .in the reservoir until it is released by.a manuall operated releasing mechanism, which will now proceed to describe. i

The base 1 is divided into an upper comartment 26 and a,lower compartment 27 'y a lateral floor or partition 28. There is 1 I a pull bar 29 for each reservoir having a hand hold or knob 30 on its end extending through the front wall of the base, and the opposite end is provided with a lateral projection or hooked end 31, which overlaps a complementary hooked end 32 on a valveactuating rack bar 33. The valve-actuating rack bar has its upper-edge 34 meshing at all times with the teeth 35 of the pinion 36 on the valve stem 37 to operate the valve in the discharge pipe 38 in the bottom of the reservoir 2 and communicating with the nozzle 39 adapted to be introduced into the filler tube of the motor vehicle receptacle to be vfilled.

Above the

bars

29 and 33 is a coin chute 40, through which a coin, check or token may be introduced to drop in the space between the hooked end 31 and the hooked end 32, constituting a connector between said

bars

29 and 33. When the coin drops between the bars, it will connect them so that when the pull bar is moved outwardly, it will impart movement to the rack bar '33 and thereby open the valve on the valve stem 37 and allow the oil to discharge from the reservor 2 through pipe 38 and nozzle 39. When the rack bar 33 is moved forwardly, it will be held in that position by a pivoted pawl 41, carried by the floor 28 and having a rule joint connection 42 with a link 43 on the end of the eccentric bar 44 actuated by the eccentric 45 on the end of the drive shaft of the motor 6. i

The rule joint will permit the pawl to give when the bar 33 is pulled outwardly to open the valve for the discharge of the liquid but will engage one of the ratchet teeth 46 to.

a will be held in its outward position by the prevent a retrograde movement which .the tension spring 47 may impart to it when it is unobstructed. The pawl will hold the bar out to keep the valve'open until the contents of the reservoir 2 is discharged. When it has been discharged, the contact 16 will be resting on 24 so that the switch in the switch box 9 will close the circuit between the service line and the motor and cause the cam 45 to impart an oscillatory movement tothe bar 44 and to move the toe of the pawl out of engagement with the ratchet and permit.

pawl so that the valvein pipe 38 can remain open. I I The mechanism described is for but one of the reservoirs 2 and its complementary feeding and discharging mechanism, it being obvious that duplicate

reservoirs

49 and 50 will be operated by identically the same mechanism except that all of the reservoirs in any bank can be connected up to the discharge pipe 38. The pumpi mechanism,v

- other without waiting for a refilling of the reservoir which has just been exhausted and instead of connecting all of the reservoirs to v a single discharge pipe38, single discharge pipes can be provided if desired, so that more than one consumer can be supplied with gasoline at the same time.

What I claim and desire to secure by Letters Patent is:-

1. A fluid dispensing device comprising a reservoir, means for introducing fluid into the reservoir, a discharge pipe leading from the bottom of the reservoir, a valve in the pipe having a stem provided with a pinion, a spring-re-tractible rack bar engageable with said pinion, means for operating the rack bar in opposition to the spring, a pawl to normally hold the rack in extended position, and means for mov'ingthe pawl out of engagement with the rack.

2. A fluid dispensing device comprising a reservoir, means for introducing fluid into the reservoir, a discharge pipe leading from the bottom of the reservoir, a valve 'in the pipe having a stem provided with a pinion, a spring-retractible rack bar engageable with said pinion, means for operating the rackbar in opposition to the spring, a pawl to normally, hold the rack in extended position,

and motor-actuated means for moving the pawl out of engagement with the rack.

3. A fluid dispensing device comprising a reservoir, a motor-actuated pump for sup plying the reservoir withliquid, a pipe leading from the bottom of the -reservoir, a valve in the pipe having a stem provided with a .pinion, a spring-retractible rack meshing with the pinion, the spring being normally eflective'to hold the rack 1n aretracted position to maintain the valve closed, means for moving. the valve against the action of the spring, a pawl for holding the rack in its non-retracted position, means for actuating the pawl connected to the'motor, and means within thev reservoir for causing the motor, to operate when the means is-in one position and to cause the motor to cease operating when the means is in the opposite position.

4. A fluid dispensing device comprising areservoir, a pipe leading therefrom, a rack, a valve in the pipe'having a pinion meshing with the rack, a spring for moving. the rack in one position, an actuator for moving the rack in the opposite position, a pawl normally engaged by the rack, the pawl having ajoint whereby the rack may tilt the pawl when it is slid in one direction and whereby the pawl will actively engage the rack to hold it against movement in an opposite direction, and means for actuating the pawl to release the rack.

In testimony whereof I aflix my signature.
