Y. APPARATUS FOR HANDLING FLUIDI FUEL.

9 au whom 'tt may concern:

lie it known that I, Riemann S. MrrCHnLL, citizen of the United States, residing at lorgantown, in the county of Morgan an'd tate of Indiana, have invented certain new .1d useful Improvements in Apparatus for landling Fluid Fuel, of which the followlg is a specification. Y

T he object of my present invention is to. rovide an apparatus whereby fluid fuel, specially gasolene, can be supplied for con- .unption in a safe, economical and easily egulated manner.

l have illustrated this appamtusas aranged to supply gasolene to an ordinary asolen cooking stove; but it may obviusly be also utilized in supplying the fluid nel to gasolene engines, or to any other sort f burners, or for any other purpose which nay be desired. y l

Referring to the accompanying drawings, figure l is an elevation of a gasolene stove n position for use with my improved fluid uel supplying apparatus arranged in suit- Lble relation thereto and connected therewith; Fig. V2 a detail sectional view, on a '.onsiderably enlarged scale, of the tank con- .aining the fluid fuel and the pipes ilnme- `liately connected therewith-the float for ,ndicating the condition of the contents of .whe tank being also shown, and F ig. 3 a derail vertical sectional view of those portions af the pipes or tubes and immediately adjacent parts which are arranged in proximity to the point of consumption.

In the illustration given an ordinary gaso lene stove 21 is connected, by means of a e 22 having branches 23 and 24, with the luid fuel supply, which replaces the tank commonly used to contain such fluid fuel. The upper portion of the supply apparatus consists of a tube. 3l having a branch 32 to which the pipe 22 is immediately connected. `Within the member 3l is a float 33 from `which a small rod 34 extends up through cap 3.5 of art 31. From the lower end of part 31 a py ain tube 3G leadsto the upper end of the main fluid fuel vsupply tank, lor to a tube extending upwardly therefrom. This fluid fuel Vsupply tank 41 is shown as cylindrical' in form, with ends of conical shape. From the upper cone-shaped tank-end a (pube 42 extends; and, in the construction sh Wn, the supplyfpe 36 branches off from this tube a short ist-ance above the point Where it joins the tank. Another pipe 43 also leads Specification of Letters Patent.

from said tank, preferablyv its lower end,

and returns upwardly to a point alongside the lower portion of pipe ortube For purposes of protection and rigid and durable construct-ion this pipe 43 is shown as passing through one side of tank 41; but, obviously, it might. (without'in any way affecting its` functions) pass up outside of and free from said tank. Near its upper ond a branch pipe 44 leads up to the vicinity of the point of use, near the part 3l. rlhe up pei` part 45 of this pipe 44 `should be of rubber hose (or some such flexible material) for. pur oses which will presently be explained. Sai pipe 44-45 terminates in a connection with a funnel 4G; and said funnel, as best shown in Fig. 3, is usually suspended to the wall of the building, as by means of a loop 47 connected to said funnel and a suitable nail or pin 4S driven into the wall. Tater is' introduced into this funnel for the purpose of displacing the fluid fuel in the tank 4l and forcing the same up to the point of consumption.

Il am able to produce the proper results with this apparatus in the following inanner: Fluid fuels (such as gasolene) and water, are of diiferentspecitic gravities, the fluid fuel being lighter than the water. The two substances will not cominingle, therefore, when placed in the same vessel. take advantage of this fact in the manipulation of this apparatus. I will first describe the introduction or renewal of the supply of fluid fuel into the tank 41:

'ith the parts in the condition shown in Fig. 2, the caps closing the upper ends of the pipes 42 and 43 being removed, and the pipe 42 extending to a considerable dist-ance above the `upper end of pipe 43, the branch pipes 3G and 44-45 being either closed or leading to a still higher level, l am able, by pouring the fluid fuel into lthe upper end of pipe 42 to displace the water which may be'in the lower portion of t-he tank and cause the vsame to'flow out of the top of pipe 43. The pipe 42 has a removable cap 42', and the pipe 43 a removable cap 43. These are kept closed while the apparatus is in use, but are removed when the supply of fluid fuel in the tankis to be renewed in the manner above described. Then the'cap 42' is removed I preferably att-ach a funnel in its place, as is indicated by dotted lines in Fig. 2.

In order to know the character of the tanks contents, and thus avoid Wasting, the

lluid fuel, l provide a float 5l of such character and construction that it will float on water and will sink through the liuid fuel. When the upper end of ltube l2 is opened,

therefore, the rod o2. which extends up froin float 5l will project out frein the top of tube p 42 a distance equal to the depth of the water in the lower portion of the tank ell. When t tube it indicates that the tank has been fully i supplied with the liquid fuel. When this is f done the caps should be screwed on tightly onto both the tubes -lZ and e3, and there reinaiii until a new supply of -luel is iiecesi sary. ln the consumption of the liuid l also 1 take advantage of this saine dill'crence in the specific gravities of the two substances.

'l` he branch 32 through which the fluid fuel liows to the point of consumption is Sulliciently higher than the funnel -lti to substantially balance this difference; and, in

stop; and, iiivthe case of a stove (as illustrated) the lii'e niust go out. This is a inatter ol' considerable consequence, asin case of carelessly leaving the lire unattended it will become extinguished in a short tinie.

'lhe lioat 33 enables ine to position "the funnel -lo in exactly the proper relation to the discharge branch 32 when setting up the apparatus. I move said funnel until the. fuel will just. flow into said branch. This causes the tloat 2323 to raise; and, when at this .xact point, l bend the small rod or wii'e 34, and this point is thus delinitely ascertained and preserved to indicate the correct position of the ioat in future adjustments.

llaving thus fully described my said iiivention, what l claim as new, and desire to secure by Letters Patent, iszl. 'The'combination, in an al'iparatus for handling liquid fuel, of a tank, a fuel pipe connected, to the upper end of said tank, a water pipe also connected with said tank, die upper ends of said pipes being at diflferent levels whereby the liquid fuel is eli-- abled to displace the water when introducen and cause said water to flow up to the upper end ot its said pipe, means for tightly closing said pipes when the tank has been setting up this apparatus, l adjust this dif- 1 ference to exactly the amount necessary to attain the proper pressure to secure the desired flow 0f fuel. ln installing the appai'atus the iexible portion 45 ofthe pipe lla-l5 beconics of service. ln supplying the fuel for. consumption l inake use of a vessel (5l. r[his vessel is shown as (and is preferred to be) 'a transparent vessel, as a bottle of suitable capacity, it being thus` easy to obsei've the condition ofits contents.
