To (1H whom it may concern.'

Be it known thatl, Jo'im JAMES Carnon, a citizen of the United States, residing' at Bonham, inthe county of Fanni'n and State of TexnsLhave nvcntedcertein new and useful improvements u FluidfDispensing Apparatus, of which' the following is a specifi cation.

This' invention as speciucd relates to new and useful improvements in fluid dispensing apparatus. l

The object of the invention is to provide an apparatus for dispensingl liquids such as oils and comprising a storage tank, a pressure tank, an air pressure pipe connected .to the pressure tank a discharge pipe having connection with lioth tanks, and a valve mechanism arranged to simultaneously open.

the discharge pipe and admit compressed air lo the pressure tank and to simultaneously close the discharge pipe, cut off the supply of compressed air to the pressure tank and open the pressure tank to atmosphere, thus relieving all pressure from the oil and eliminating danger in case of surrounding` fire.

Another feature resides in the provision of a small pressure tank whereby acomparatively' small amount of oil is placed under pressure and a high degree of safety maintained. A

A further object is to provide a compound valve mechanism arranged so that it is impossible to eut ofi' the discharge of oil without cutting ofi the air ressure and relieving the )ressure on the oil).

Finally the object of the invention is to provide n. device of the character described that will he strong, durable, eilicient, and simple and r-.omparativclv inexpensive to construct, also one in whic the several parte will not be likely to get -out of working order.

With the above. and other objects in view tho invention has relation to certain novel features of construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawings, wherein:

Figure l is an'elevation of the apparatus,- ccrlain parts being' shown in section, Fig. 2 is a horizontal cross-section of the liquid diecharge valve, and Fig. 3 is a similar view of the air volvo. l 4

1n the drawings' the numeral 1 designates a a atoragetenkamtebly located under ground 'and rovded with la'.suitablefilling connection 'small pressure tank 3' is connected under ground' to the lovver politiomof the storage tank by a pipe' d and may be located at any desirable point The-tank'is connectcd:to the pipe thy @piped This only a. small amount of oil is 'placed under pressure at atime. i f

Annair line pipe 6 entere the top of the pressure tank 3. In' the pipe 4 between the twotanks a checkvalve. 7 is located and arranged to permit the passage of the liquid from the storage tank 1 to .the pressure tank 3, but closes against back iovv and back pressure.

A* iuiddischarge pipe 8 is connected to the pi )e 4. Between the pipo 5 and the pipe 8 -a e eek valve 9 is located in the piped liquid-to the discharge pipe, but to prevent back flovv and hack pressure from the dis-- charge pipe l l lt 1s obvious that the 1i uid will normally and ipe. 8 and pressure in the not lorce the li uid back throng the valve 7; neither coul pressure in pipe 8 force liquid hack past the valve 9. Air under pressure being admitted to the pipe 6 places a pressure on the liquid in the small tank B, but does not` affect the liquid in the tank 1, as the valve 7 is held to its seat. Such pressure forces the liquid past the valve 9 and `into thediseharge pipe 8 from which it is dispensed. Only a comparatively small quantity of oil is placed under pressure and before additional oil can be admitted to the tank 8, the pressure must be relieved'to permit the valve 7 to open. This maintains the liquid in the storage tank 1 free from ressure at all times and reduces the fire ris At the u per end. of the discharve pipe'S a compound comprises onecut-oi valve plug 11 and one three-way valve 12, each havin the ordinary construction egcept as iereinaftcr ointed out., The plug 11 is provided with a andle 14 and controls the passage of liquid to a pipe 15 in which a suitable measuring meter 21 is connected andivhich in turn is connected to the usual dispensing hose 16.' IThe valve 10 has a'. dependingx housing 17 l, conncted .to-a valve-cas'ipir 1,8 mvvhich the 'plug 12 is arranged. e plugs ape conand is arranged to permit the tiow' of the' reach the same level in t e tank 1, pipe 6, f

pressure tank iscOmparatively small so that ilfl f. v messes nested in the housingJ es shown in Fig. 1, and so arranged that others turned simulteneously. The valve casing 18 is connected to the sir pipe 6 sind hes connection by means of s pipe 19 with s suitable source of compressed air supply (not shown). At right angles to the entrances of the pipes 6 and 19, which are slined, the casing 18 has s port 20-openin to the atmos here.

Should it be esired to disc arge the liquid ns before described, the handle' 14 1s swung to ivethe plugs a. quarter turn,

which este lishes communication bet'viveenthe piges 8 and 15 and between the pipes 6 and 1 and closes the port 20. This permits sir under pressure to iiow to the tank und force'the liquid out through pipe 8 to the meter und hose 16. When the handle is swung beck to its normal position the plugs nre turned so that the dow of liquid is cut ofi and the flow of sir from the pipe is also cut of?. At the same time connection is established between the pipe 6 and the port 20, thus relieving,r nll'pressure in the tunk 3 and pipoi.k

'it will be apparent that the plugs are simultaneously operated and it is impossible to open the discharge pi o without admitting sir to the tank 3, an also the discharge con not be cut o' without also cutting ofi' the supply 'of compressed air to the tank 3 and opening said tank to atmosphere, thus relievmg the pressure on the liquid.

. 'Whitt I claim is:

A'uid dispensing apparatus, comprxslru7 a. fluid storage tank, n supplementary tank disposed at a level lower than that of the storage tank, a. uid conducting connection between the two tanks, a check-valve interposed in said connection, permitting a 'dow of uid only from the storage tank to the supplementary tank, n. discharge ipe, hsvingcommunication with the supp ementery tank and extending to an elevation above the storage tank, a. check-valve interposed in the discharge pipe, ed'acent to the supplementory tank, permitting fluid to ow through said pipe from but 'not to the supplementary tank, an air pipe communicating` with the supplemento. tank, and a volvo normally closing the discharge pige and openino' tho air pipe to the atmosp ere, the discharge pipe being open und the air pipeconnected with a source of compressed air in the other .limiting positlon of the .valve In testimony whereof I hsve signed my nume to this specification in the presence of two subscribin witnesses.
