w. HADDON ELECTRIC ACCUMULATOR CASING Filed Jan. 15, 1926 Patented June 21, 1927.
UNITED STATES WALTER HADDON, OF LONDON, ENGLAND.
ELECTRIC ACCUMULATOR CASING.
Application filed January 15, 1926, Serial No. 81,575, and in Great Britain January 19, 1925.
This invention relates to, and has for its object the provision of improvements in, electric accumulator casings.
The invention resides in the arrangement according to which while there is a ventilation or sweating hole for the gas in the closure of the casing, any of the acid which may well or splash to the outside of said closure tends to run back to the interior of said casing.
One embodiment of the invention is illustrated in the accompanying drawings and the same will now be described, it being understood that the particular construction illustrated is susceptible of various modifications without departing'from the scope of the invention as defined in the appended claim.
In these drawings Figure l is a side elevation of an accumulator casing and closure therefor.
Figure 2 is a section on line AA of Figure 1.
Figure 2 15 a part sectlonal view of a modification.
Figure 3 is a plan with closure removed.
Figure 4c is a plan of the closure.
In these drawings the casing 1 and the closure 2 (from the latter of which the accumulator plates may be supported) are both made of lead or lead alloys and the closure 2 is adapted to rest on a horizontal ledge 3 formed around the interior of the casing at such a distance below the rim thereof that when the closure is in situ the said rim of the casing extends to a level above the upper surface of the closure.
This arrangement has the advantage inter alia that by providing a recess 7 in the wall of the container or casing 1 and a packing ring 8 carried in a co-operating recess 9 in the closure 2 a leak-proof joint is formed when the closure is applied and pushed down on to the ledge 3. This arrangement is shown in Figure 2 The closure furthermore is provided with a filling hole in which a closing plug 4 isadapted to screw, and the upper end of this filling hole-terminates in an enlarged concave recess 5 formed in the upper side of the closure. Finallythe closing plug 4 is formed with a ventilation or sweating hole 6 which comes out sideways at a level a little above the level of the surface of the closure.
From the above it will be seen that, should any of the accumulator acid splash or well to the outer side of the closure it will be prevented from spilling by the rim of the easing (which as aforestated extends above the upper surface of the closure) and will tend to run back into the casing either by gravitating into the enlarged recess 5 and thence draining through the screw threads of the closing plug or else by draining between the, contacting surfaces of the closure and the casing.
With regard to the construction of this embodiment the casing and the closure consist each of one integral lead casting, and'for constructional convenience and also for purposes of economy the thickness of these castings is maintained small and largely constant throughout. Thus the ledge 3 around the interior of the casing is formed as shown by the whole portion of the walls above said ledge being outwardly set with respect to the remainder of said walls and similarly the enlarged recess 5 at the upper side of the closure is formed by a bodily downward displacement of the material of the closure.
The closure moreover is formed with downwardly extending vertical flanges 2 which rest on the aforesaid ledge 3. The closing plug 4, moreover, is preferably dished at its inner end.
What I claim and desire to secure by Letters Patent is In combination, an accumulator casing proper formed with an interior horizontal ledge, a cover formed with a filling hole adapted to rest on said ledge, and a plug, formed with a vent hole, adapted to fit removably in said filling hole, the upper surface of said cover being below the upper edge of said casing proper, said filling hole at its upper end being expanded so as to provide a sunken annular clearancearound said plug and, at its lower end, being'adapted to provide a sufficiently inexact fit with said plug to permit of the draining back of acid from said upper surface of said cover, and said vent hole coming out above said upper surface of said cover so that acid cannot drain back through said vent hole.
In witness whereof I afiix my signature.
WALTER HADDON.
