This invention relates to water-proof joints and its principal object is to provide a water-proof joint between a sheet metal tank or container, and a pump or other object mounted thereon. Many attempts have been made to provide water-proof joints for this purpose, but they are expensive in construc-. tion, diflicult to install and not entirely reliable. One object of the present invention is to provide an imperforate reinforcement member at the place where a pump base or other object is to be secured to a sheet metal tank, said imperforate reinforcement member being welded to. the sheet metal tank and serving to hold the bolts or screws that fasten the pump base or other object, to the tank, in such manner that no liquid may possibly pass to the interior of the tank. Another object is to provide means for a sheet metal tank, to which a pump base or other object is to be bolted, whereinthe bolt holes are not exposed, in any manner, to the interior of the tank. The invention consists in the several novel features hereinafter fully set forth and claimed.
The invention is clearly illustrated in the accompanying drawing, in which 2- Fig. 1 is a vertical section through fragments of a tank and pump base, showing a simple embodiment of the invention applied thereto; Fig. 2 is a fragmental, vertical section showing the parts disassembled, and Fig. 3 is a bottom view of the parts seen in Fig. 1.
Referring to said drawing, which illustrates one embodiment of the invention, the reference character 5 designates a fragment of the top wall of a sheet metal tank, such as is commonly used for dispensing gasoline, oils and other liquids. Upon the top of the tank is a pump base or other object 6 which is in open communication with the interior of the tank through an opening 8. The pump base is ordinarily secured to the tank by bolts and nuts, but as soon as any bolt or nut becomes loose the joint becomes leaky and water may enter around the bolt and through the bolt hole in the tank. To eliminate this possibility I provide a ring or collar 7, which completely surrounds the opening 8 in the tank, and is welded to the tank along the inner. and outer edge portions 9, 10, of the ring or collar. The welding may be done with a gas flame or by electric welding process as desired. The tank 5 and ring or collar 7 are then drilled and tapped at various places along the ring or collar as at 11. The holes 11 are drilled only part way through the ring 7 so as to leave a closed end 12 below the hole. By drilling the holes only part way into the ring there is no possible way for water to enter the tank throughthe bolt holes. A comparatively'thin ring 7 may be used if desired,'.
but in such case it is preferred to increase its thickness at the places where the bolt holes are formed, and this may be done by forming lugs 20 on the underside of the 7,.
ring. idelativelylong bolt holes may be made 1n the lugs as Wlll be seen from the drawing.
' or recess 19 for the reception of said raised ing ring 18, may be interposed between the tank and flange 13 of the pump base.
Any water that collects on the top of the tank cannot enter the tank through the bolt holes 11 because the edge portions of the ring or collar 7 and tank wall are welded together. Moreover, the water cannot enter between the tank and pump base because of the raised flange portion 16. In case one or more bolts become loose, water is still prevented from entering the tank, for the same reasons. v
,More or less variation of the exact details of construction is possible without de parting from the spirit of this invention; I desire, therefore, notto limit myself to the exact form of'the construction shown and described, but intend, in the following claim, to point out all of the invention disclosed herein. I
I claim as new, and desire to secure by Letters Patent:
A water-proof joint comprising a sheet metal tank Wall having an opening therein,
the marginal edge portion at the opening being bent upwardly, a ring surrounding said opening and Welded along its inner and outer edges to the underside of said sheet metal-tank Wall, there being bolt holes extending through said tank Wall and only part Way through said ring, a pump base over said opening, recessed upwardly to receive said upturned edge of the tank Wall, and having a flange, overlying said ring, 10 and bolts threaded in said bolt holes and having heads bearing upon said flange.
EDWIN ARNOLD.
