This invention relates to new and usefulimprovements in a uid dispenser. One object of the invention is to provide a dispenser for gasoline, oils, or other fluids,
and which may be operated to discharge a predetermined quantity of the liquid, through the instrumentality of a coin inserted into a suitablecoin slot, provided for the purpose,-
said coin constituting the purchase' price of thequantity to be delivered.
Another object resides in the provision of an apparatusof the character described which ,is normally locked against operation, so that no delivery can be made until a coin of the v proper denomination is placed in the coin slot and which becomes an element of the apparatus to permit the actuation thereof, to eifect' delivery.
Another feature of theinvention resides in the provision of means for regulating the amount of the liquid delivered, so that as the price of the merchandise varies, the quantity delivered for any xed price may be correspondingly varied.
With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation, and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein The figure shows a vertical sectional view of the device.
In the drawings the numeral 1 designates a suitable housing for the operative mechanism. Mounted on this housing there is a fluid container 2, constituting a measuring chamber. The numeral 3 designates a supply tank, preferably underground in which the Huid to bedispensed is under pressure. A supply line 4 leads up from the supply tank 3. The upper section 4 of this pipe enters the bottom of the measuring chamber 2 through a gland 5, and the-lowervend of this section telescopes in the supply line 4 through the gland 6. There is an overflow line formed of the lower and upper sections 7 and 7 the former of which is connected to, and upstands from, the tank 33, and the latter of which extends through the gland 8, in the bottom of the measuring chamber and has its lower end telescoping in the section 7 through the gland 9, said glands 5, 6, 8, and 9, forming Huid tight joints.
4' and 7', one side of which is formed with a There is a clamp 10 fastened to the sections rack face 10 which is in mesh with a spur gear 11, fixed on the shaft 12. This shaft is rotatable in suitable bearings in a frame 13, and may be rotated by the crank 14 to move the bracket 10, and the pipe sections to which it is secured, up or down, said pipe sections working through the glands above described.
A discharge or service line 15 leads from. the bottom of the measurin chamber 2, and preferably terminates in a exible hose 16.
The supply and discharge lines are controlled by suitable cut- oill valves 17 and 18 respectively, of conventional construction, and actuated through the respective stems 19 and 20. Actuating levers 21 and 22 are provided, the former of which has a sliding pivotal connection, at its upper end, with the stem 19 and at an intermedlate point is pivoted to the bracket 23, which is ixed to the casing of the valve 17, and the latter of which is pivoted at its upper end to a bracket 24, fixed to the casing of the valve 18, and at an intermediate point has a sliding pivotal connection with the stem 20, the lower ends of each of said levers being free. Coil springs 25, and 26, are attached at one end to the free ends of said levers, and at their other ends they are anchored to fixed anchors above the pivotal points of attachment, of said levers to said brackets.
Attached to the upper end of the inlet or supply pipe there is a valve casing 27, whose upper end has 'a valve seat 28, which is controlled by the downwardly opening valve 29 which is attached to the lower end of the valve stem 30. There is a lever 31, pivoted at one end to the upper endvo the overflow line and attached to the other end of this lever there is afloat 32. The valve stem is pivotally connected at its upper end to the lever 31.
When a predetermined amount of. the liquid to be dispensed enters the measuring tank, the float will be elevated, and the valve 29 thereby closed. Should there be any leakage past said valve, or an excess liquid in any way enter the measuring chamber, the excess will overflow back into an overflow tank 33, through the overflow line. If the price of the commodity should increase, a smaller quantity should ,be delivered, for a fixed price. and to bring this about the crank` ing relief valve 35 which is normally held closed by the pressure 'from the tank 3. At intervals the pressure may be cut olf from said tank 3, and thereupon the valve 35 will open and the contents of the overlow tank will drain into the supply tank 3.
The numeral 36 designates a manually operable valve actuating push bar, which 1s slidiible in the long bearing 37 in the hous.
ing, and whose outer end projects out from the front side of said housing and is formed into a push knob 38. A coil spring 39 1s 1nterposed between said knob and the housing, and surrounds the projecting -end of said bar. This bar is formed with a shoulderl 40, and there is a pivoted spring actuated latch 41 formed with a shoulder 42, spaced from, but in position, normally, to 1nterlock vwith the shoulder 40, to lock the bar 36 against operation. chute 43 in the housing which normally aligns with a side notch 44, in the bar 36, and when a coin, as 45, is inserted in the chute, it will drop into said notch, and upon actuation of the bar 36, the coin will contact with the upwardly beveled free end of the latch 41, and lift said latch to permit the further actuation of said bar.
There isa manually operable valve reversing bar 46, slidable in suitably aligned bearings, and one end of which projects out from the front side of the housing and is formed with a push knob 47, ald interposed between said knob, and the housing, and surrounding the projecting end of said bar there is a spring 48.
In operation the valve reversing gear 46 is first operated and the levers 21, and 22, are thereby moved from the positions indicated in dotted lines, to positions indicated in full lines by the lugs 49 and 50, carried by said bar 46.
The push bar 46 is then returned by the action of the spring 48, and the parts assume the position as shown in full lines in the drawings. The valve 17 is now open and the valve 18 is closed and the measuring chamber 2 will now fill and lift the float 32. When the required amount of liquid is in the measuring chamber, the ioat will lift the valve 29, and shut ofi th`e supply, any surplus that may have entered said chamber draining oil' through the drain pipe, as heretofore eX- plained. The coin is now inserted and the bar 36 actuated. There is a cross link 51 operable on a fixed pivot 51 intermediate its ends and the upper end of this link is connected to the bar 36. The lower end of link 51 is pivoted to the sliding bracket 52. When the bar 36 is actuated, it will move said bracket in the opposite direction, and the lugs 53 and 54, carried thereby, will contact against and actuate the levers 21 and 22, in reverse direction. When the springs 25, and 26 pass center they accelerate the movement of the valves There is a coin.
and cause a quick action thereof. The valve 17 is now closed, and the valve 18 is opened, the position of the lugs 53 and 54, relative to said levers being such that valve 17 will close before valve 18 opens. The liquid in the measuring chamber will now be discharged through-the service linc and delivered to the customer.
There is a safety lock consisting of the locking rod 55, which has a sliding pivotal connection at its upper end with the latch 41, and is vertically slidable in suitable bearings, provided for it, the lower end 56 forming a lock bolt. When the latch 4l is lifted, this bolt seats in an aligned notch 57, cut in the underside of the bar 46, and locks said bar against a second operation until the bar 36 has been returned to initial position, thus completing a cycle of movement.
Within the measuring, chamber there is a vertical gauge 58 by the use of which the overflow pipe may be accurately adjusted as is required on account of price variations, and on the outside of said chamber there is a similar gauge 59 for the inspection of customers.
The coin 45, upon actuation of the bar 36 is moved into alignment with the coin delivery chute 60, and passes therethrough, and falls into the coin receiving receptacle 61 provided to receive it.
