Application led June 23, 1918. Seri'al lim/105,390.

To all whom z't may concern:

Be it known that I, LOUIS KBssLER, a citizen of the United States residing at Chicago, in the county of dook and State of Illinois, have invented certain new and useful Iinproven'uents in Filler-Tubes and Closures Therefoi' for Receptacles, of which the following is a description.

My invention belongs to'that general class of devices known as filler tubes, and particularly vrelates to an improved tube and closure for the same. The invention has among its objects the reduction of a device of the kind describe that is safe, simple, eiicient, durable, com act and satisfactory for the purpose, whic may be used wherever found applicable. The invention has particularly among its objects the production` of a closure that may be used in connection with any suitable form of Iiller tube or filling opening of a receptacle for closing the opening where the tank is lilled, whereby excessive pressure in the tank may be re-- lieved, and Where as the contents of the tank are drawn off air may be admitted to fill the space formerly occupied by the liquid. The creating of avacuum in the tank, and consequent impairing of the discharge is pre-- vented, and at the saine time the escape of gas from the tank due t0 evaporation, 1s prevented. Other objects and advantages of the construction herein set forth will be 0bvious to those skilled in the art from the disclosures herein 'veiL To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and -described, and more in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fi re 1 is a sectional view taken substantially on line 1-1 of Fig. 3.`

Fig. 2 is a sectional View taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a sectional View taken substantially on line 3 3 of Fig. 1

particularly pointed out` Fig. 4 is a sectional view taken substantially on line -l1 of Fig. 1, and

Fig. 5 is a sectional view taken substantially on line 5 5 of Fi 1.

Referring to the drawings, 1 is'a tube of suitable material provided with an extending flange 2 at the upper end, formed integral therewith, if desired, the same being suitably formed in any desired manner for attachment to a tank 3, or the equivalent. The tube 1 is preferably extended as at 2 above the flange 2, and is shown threaded at the exterior. Where'the tube is made for threaded engagement with .the tank, the Harige 2 may be formed similar to a nut, so as to plermit its being engaged by a suitable wrenc when desired. The lower end of the tube is open, and the same being covered with a lWire gauze 4:, which may be reinforced and protected by the coarser wire gauze 5, thereby preventing the gauze 4 froml being easily fractured. The tube is also preferabl formed with openings or apertures 6 t ereabout. near the bottom, which are lcovered with wire gauze 7. I have shown a flanged collar S'arran ed at the bottom, forming a convenient met od of securing the gauze parts to the tube, it being `understood that the same maybe soldered or otherwise securedn place. I also provide the tube with a series of openings or o ertures 9, arranged adjacent the to this Ieilig covered by gauze 10, secured'lie. placein any desired manner.

Arranged within tube 1 and spaced from, is an inner tube 11, which is formed with a iange 12 of a size to closely fit the inner wall or tube .1,- the same being ribbed as at 14eV if desired to provide spaces 13 above the flange and aid 1n maintaining the parts in position. The inner. tube in the preferred construction is of such length that the upper end 11 is adjacent the upper end 2 on the outer tube, and the partition 12 is' heilig of any desired size and shape, and the bottom is closed as at 16.

The closure for the tube consists of a neck part 18 arranged to be secured to the end of the outer tube, the same having one or more openings 19 through the same, and preferably recessed as at 20. Arranged on the part 18 is aoap 21, the same being chambered as at 22, and arranged to sealt on the top 23 of part 18. As moet clearly shown in Fig. 1, the part 21 is extended as at 24 to fit the recess `2.0, and internally flanged as at 25. Projecting through the part 18 and the part 21 isl a tubular stem 27, the saine being flanged as at 28 to overlie the flange 25. Arranged about the same is a spring 29, which bears against pant 18 and the tubular part 39 carried by fthe tubularpirt 27, the

spring normally maintaining the cap. part 2.1

in the position shown in the drawings, so that the ange of .the part is seated on the top or seat 23 of part 18. As I have mentioned, part '27 is tubular, the same having a chamber 30 communicating with the inlet duct 31, fthe part being formed with a valve seat 32.

Arranged on the end of stem 27 is a cap 33, which is chambered and provided with ducts 35, extending therefrom to the exterior, preferably at the sides. Within the chamber 30 is arranged a valve 36, which is normally maintained closed or against its seat 32, by the member 37 and spring 38, or equivalent means vfor the purpose. Part 39 is formed with a duct 40, the pant being shouldered 'so as to support the end of the Spring 38.

When it is desired to fill the tank to which the 'tube is applied, part 18 is removed, carrying with :it the several parts described as iforming the closure. The liquid may then be poured into the tank, from whence the same passes through the openings 15 into the space between the tubes, and tluiough the wire ganzes 4, 5 and 7 to the interior of the tank. The air displaced within the tank passes through ythe wire gauze 10 and openings-9, through the Spaces 13 between the tubes rte the exterior. Any dame is prevented rom ente-ring the tank by the gauze 4, 5, 7 and 10, so that the tank cannot explode at the ller opening while the closure is removed for fill-.ing the tank, or when the closure is replaced. In case of any pressure within the tank for any reason whatever the same will be relieved by the raising of .the part 21, Ithe gas passing through the chamber out thiough the opening 19, and under the cap between the same and ite seat. As the fuel is used up the forming of a vacuum within the tank is prevented by the admission of air through 'theopenings 35, duct 31, past the valve 36, through the chamber 30,

als

11 into chamber 13, and through the openings 9. The valve 36 prevents the escape of any fumes or gas from the interior of the tank. This is important, asin practically all garag the fumes from the fuel tank fill the places, subjecting the same to possible fire and explosion. Of course where the tubes shown are not employed, the closure may be used in place of the ordinary cap, the lpressure in thetank being relieved or air admitted, etc., as described, but the tank, however, is not explosion proof.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same Without depanting from the spirit of my invention; hence I do not wish to be understood as lim'- iting myself to the exaot form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
