FIDL CAP FOR GASOLINE TANKS Filed May 29, 1929 a j Z ag wmew Patented May 31, 1932 UNITEn srarss GEORGE W. ISBELL, F BALTIMORE, MARYLAND FILL CAP FOR GASOLINE TANKS Application filed May 29,
This invention relates to fill caps for gasoline tanks and more particularly to that type of structure wherein the gasoline tank is p0- sitioned beneath the surface of the earth and is provided with a fill pipe extending upwardly from said tank, the upper end of said pipe being fitted with a cap the top of which is flush with the ground or the surface of a pavement.
The primary object of this invention, is therefore, the provision of a fill cap, which is simple in construction, easy to manufacture, and eflicient in operation. ther objects of this invention will become apparent as the description thereof proceeds, reference being had to the accompanying drawings wherein Figure 1 is an elevational sectional view of the fill cap as applied to a fill pipe and gasoline tank.
Figure 2 is a partial sectional view taken on line 2-2, Figure 1, looking in the direction of the arrows.
A gasoline tank 1 is placed in the ground and has attached thereto a fill pipe 2, the upper end of which terminates short of the sur face of the earth or the pavement 3. Attached to the upper end of the fill pipe 2 is a fill cap 4, said fill cap comprising an upper cylindrical portion an intermediate cylindrical portion 6 and a lower cylindrical portion 7. The lower cylindrical portion 7 is interiorly screw threaded as at 8 so that the fill cap 41 may be threaded on the upper end of the fill pipe 2, which is adapted to abut the open partition or stop 9 when the fill cap 41 is screwed all the way down. The stop 9 separates the intermediate cylindrical portion 6 and the lower interiorly threaded cylindrical portion 7. said intermediate portion 6 being adapted to receive a lock (not shown) and is provided with a recessed portion 10 the purpose of which is to receive the latch or bolt of the lock when the same is locked in place.
The upper cylindrical portion 5 is larger in d ainr-ter than either the intermediat or lock portion 6, or the lower or screw threaded portion 7, the upper end thereof being open as at 11 and the lower end thereof being formed with a circular shelf 12, said cylindrical por- 1929. Serial No. 366,929.
tion 5 being adapted to receive a closure plug 13. Positioned within the plug receiving portion 5 of the fill cap l and in press-fitted engagement therewith is a brass sleeve or bushing 14, the fill cap 4 being preferably made of steel or other suitable material.
The closure plug 13 comprises two connect ed upper and lower members 15 arid 16. The lower member 16 is cylindrical in shape and formed with an upper extension 17 of a reduced diameter said extension 17 being provided with a screw threaded opening 18. The upper member 15 is also cylindrical in shape and is provided with a depending portion 19 of reduced diameter said portion 19 being provided with a threaded extension 20 adapted to fit within the threaded opening 18 in the member 16, so that the extension 17 will abut the depending portion 19, forming between the members 15 and 16 a peripheral recessed portion 21. i
Positioned within said peripheral recess 21 and seated on the lower member 16 is a cup shaped washer 22 of leather or rubber, or any oth r suitable material, the vertical wall of said washer 22 being substantially flush with the cylindrical surface of the members 15 and 16. A helical spring 23 of circular shape is positioned between the wall of the washer 22 and the depending portion 19 of the member 15 and is adapted to press said wall into tight engagement with the sleeve 14: and to maintain the plug 13 in fluid tight engagement with the wall of the fill cap 41. It is apparent that the coil spring 23 and washer 22 are positioned on the respective members 15 and 16 before the same are attached to eacn other.
To facilitate ready removal of the plug 13, the upper member 15 is provided with a circular recess 2-1 in its top, and a pin 25 is inserted transversely through said member and adapted to pass through said recess 24:, said pin being rigidly secured to said member 15, The pin 25 in the recess 24; provides a means for pulling the plug 13 out of the fill cap When it is desired to put gasoline in the tank, the plug 13 is first removed, then the look (if in place), and the nozzle of the gasoline hose is inserted into the plug receiving portion 5,
the gasoline then flowing through the fill cap into the fill pipe 2 and into the tank 1.
WVhile a preferred embodiment of the fill cap has been shown and described, it is obvious that the same is susceptible of various modifications within the scope of the appended claims.
I claim 1. A vapor tight closure for hollow cylindrical members, said closure comprising an upper cylindrical member and a lower circular member, a depending extension on said upper member of reduced diameter, a threaded opening in said lower member, a threaded extended portion on said extension of said upper member adapted to be threaded into said threaded opening, a cupped washer positioned in the peripheral recess defined by said upper and lower members, and a circular helical spring disposed between said cup washer and said extension on the upper mem ber adapted to hold said washer in engagement with the hollow cylindrical member.
2. A vapor tight closure plug for hollow cylindrical members, said closure plug comprising an upper cylindrical member and a lower circular member, a depending extension on said upper member of reduced diameter, a threaded opening in said lower member, a threaded extended portion on said extension of said upper member adapted to be threaded into said theraded opening, a cupped washer positioned in the peripheral recess defined by said upper and lower members, and a circular helical spring disposed between said cupped Washer and said extension on the upper member adapted to force said washer into tight engagement with the hollow cylindrical member.
3. A vapor tight closure plug for fill boxes, comprising an upper cylindrical member and a lower cylindrical member, extensions on each of said members of reduced diameter, a threaded opening in the extension of said lower member, a threaded extending portion on said extension of said upper member adapted to be threaded into said threaded opening, a cupped washer positioned in the peripheral recess defined by said upper and lower members, and a circular helical spring disposed between said cupped washer and said extension on the upper member adapted to force said washer into tight engagement with the fill box.
In testimony whereof I atfix my signature.
GEORGE W. ISBELL.
