SURFACE DISCHARGE APPARATUS FOR TANKS.

Specification of Letters Patent.

macaw filed Januar 22, 1913. Serial in. 743,431.

Apparatus for Tanks, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My present invention is in the nature of an improvement upon thatdescribed and claimed in Letters Patent of the United States No. 1,040,872, granted to me on Oct. 8th, 1912, as hereinafter more fully set forth and particularly pointed out in my claims. My present invention, like my former one, relates to a combined surface feeder and strainer for feeding gasolene from supply tanks to gasolene engines or the carbureters thereof, and has for its object the provision of an improved feeding device of this character by means of which the gasolene is not only withdrawn from the upper part of the supply in the tank near the surface thereof, instead of being withdrawn from the lower part thereof, which naturally holds the greatest amount of sediment and foreign matter, but effectively excludes from the supply withdrawn from the tank even such foreign matter as may be carried in the upper part thereof, as well as any water which may be contained in the gasolene.

In the accompanying drawings Figure 1 is a vertical section of one end of a. gasolene tank showing my novel feeding device in elevation therein; Fig. 2 a perspective view of the base plate of my novel device and some of the parts carried by it; Fig. 3 a vertical section of the parts shown in Fig. 2 in the plane indicated by the dotted lines 83 of Figs. 1 and 2; Fig. 4 a perspective view corresponding with Fig. 9-,but showing a modified construction in which the base plate supporting-the operating parts is detachably secured to the bottom of the tank; Fig. 5 a vertical section corresponding to Fig. 3, but showing the modified construction of Fig. 4; Fig. 6 a. sectional detail of Fig. 4 in the plane of the dotted lines 6- -6 of said figure; 7 a sectional detail of the float and strainer and upper end of the delivery pipe by which they are carried; Fig. 8 a perspective view of the strainer or filtering that figure.

9 a sectional dc tail of Fig. 3 on the dotted lines 9-9 of The same letters of reference are used to indicate corresponding parts in the several views. 7

The tank A, containing the supply of gasolene, is provided in its bottom with an Patented Nov. 7, leis.

opening B, circular in form in the present instance, the closure for which opening is formed byjwhat may be termed the base plate or supporting plate C of my novel feeding device. I This plate '0 is likewise circular in form in the present instance, and

is provided, at a suitable distance within its periphery, with an annular shoulder which projects into and fits within the. circular opening 13 in the bottom of thetank, the plate as-a whole being firmlysecured to the bottom of the tank'by brazing or sweating its uppersurface, outside the annular shoulder 0, to the under surfaceof the tank surrounding the opening B'therein. The plate C is provided upon-its under surface with two integral and internally threaded depending tubular bosses D, E, the former of which constitutes a drainage outlet for the tank and carries a drain-cock d, shown in Fig. 1, while the latter constitutes the deliveryoutlet through which the gasolene is fed from the tank to the engine or other point ofconsumption, the lower portion of the boss E being reduced and externally threaded at e, for the connection of the delivery pipe.

Screwed 'nto the internally threaded upper portion of the boss E of the base plate G is the short vertically extending tubular arm 7 of an elbow-shaped castingF whose laterally projecting arm or portion f consists of an enlarged cylindrical housing and bearing for a hub G which has secured in it the lower end of the delivery pipe H, Fig.

1, which carries at its upper end the float I.

The cylindrical member 7 of the casting F is. provided, in what may be termed its forwardside Figs. 2 and i, with a segmental slot f through which the lower end of the delivery pipe H projects and in which it may have vertical play (limited by the length of the slot), as the float I rises and ner end. with a reduced extension or projecting sleeve g, Fig. 3, which fits within a corresponding bore in the horizontal portion of the casting F and furnishes communication for the delivery pipe H through the hub G, to the delivery passage within the vertical arm 7 of the casting F and the coincident passage in the lower reduced end of the boss E. Under this'construction gasolene admitted to the upper end of the delivery pipe H may flow through the same and out of the tank through the hub G and the passages in the casting F and boss E. A packing washer G interposed between the hub G and the end wall of the housing f", around the sleeve 9, prevents escape of gasolene from the tank except through the delivery pipe H andits communicating passage through the hub G and casting F.

The construction of the combined float and strainer or filter which 1 preferably employ is best shown in Figs. 7 and 8, where the body of the float I is shown as consisting of a sheet metal cup I, approximately square in longitudinal section in the present instance, whose circular. wall, adjacent its open end, is spun outwardly, at z", to form a receptacle and seat for the, closed end or bottom of a shallow cup I" which is brazed or otherwise secured in the enlarged end of the first mentioned cup. The strainer 01' filter J, Fig. 8, is in the present instance of similar size and shape to the shallow cup I", of the float, being of sufliciently less diameter than said cup to fitsnugl'y within the same as shown in Fig. 7, with its open end abutting against the bottom ofsaid cupand its closed end serving to close the open end of the cup.

I and serve as astrainer for the gasolene entering said cup. The strainer J is provided with anopening j for the passage through it of the upper end of the delivery pipe H, which is externally threaded and. screwed into the outer end of an internally threaded boss or sleeve I which is secured at'its inner end, by brazing or otherwise, to the bottom of the shallow cup I. The boss or sleeve-I is providedin its opposite sides, adjacent the bottom of the cup I, with openings i througl'i which the gasol'ene may flow from the cup 1 into the upper end. of the delivery pipe H.

'l-he combined float and strain-er, together with the delivery pipe H, are of such gravity that the float will rest in the upper portion of the gasolene within the tank A at such depth as to sufficiently submerge the strainer J and open end. of the cup 1 within the gasolene, as shown in Fig. l, and the latter will flow through the strainer J and into the upper end of the delivery pipe H, and

- pass thence. through the same and its supporting. hub G to the passages in the cast?- ingF and boss E, and the pipe leading to the engine; and as the supply of gasolene is used and its level within the tank A cor- 'respondingly lowered, the combined float and strainer will fall with the level of the gasolene, the oscillating hub G, in which the lower end of the delivery pipe H is secured, and. the segmental opening f in the cylindrical housing which incloses and supports said hub, permitting such movement of the parts. The gasolene is obliged to pass through the strainer J, in order to escape from the tank A through the delivery pipe H, and said strainer not'only serves to exclude all sediment and similar foreign matter from the'gasolene delivered from the tank, but all water as well, since when the surface of the strainer J is once wet with gasolene no water will pass through it.

In the construction shown in Figs. 1, 2 and 3, andabove described, the base plate 0, whichcarries the casting F and delivery pipe H and float and strainer J, is secured directly and permanently to the bottom of the tank A, so that access to the float and strainer, or the other parts carried by the plate C, can be had only through some other opening in the tank A. In the modified construction shown in Figs. 4:, 5 and 6, however, the base plate C is detachably se cured to the bottom of the tank A, and can be readily removed, and the parts carried by it, including the delivery pipe and float and strainer, be withdra-wn. through the opening in the bottom. of the tank which is closed by said plate when the latter is in place. To this end, in the construction shown in Figs. 4, 5 and 6, I permanently secure to the bottom of the tank A, by brazing or otherwise, an annular attaching plate K having around its inner edge a circular shoulder 72 which projects upward into and fits snugly within the opening B in the bottom of the tank A, as shown in Figs. 5 and 6. This-attaching plate K is provided upon its underside with a series of'integral depending threaded bolts L which pass through coincident holes formed for them in the base plate C, which latter is securedin position upon said bolts by nuts'M. A. packing ring N, formed of a. material impervious to gasolene, such as pigskin, is interposed between: the upper surface of the plate C and theattaching plate K, to prevent escape of gasolene from the tank through the joint between said plates. The lower ends of the nuts M are radially notched, as shown in Figs. t and 5, and the bolts L are provided with diametrical holes through which cotter pins, fitting in the notches in the nuts, are passed, to prevent unscrewing of thenuts.

-As will be understood from the foregoing description, I have provided, in. the modified construction shown in Figs. 4, 5 and 6, a construction in which the advantages of that shownin Figs. 2 and 3. are retained, and in which the additional advantage of havingthebase plate detachable, and permittion, I claim tank, is attained, which is a matter of very considerable convenience in some instances.
