- Specification of Letters Patent.
Patented @ct. 4t, 1910.
Application filed March 31, 1909. Serial No. 486,898.
sex and State of Massachusetts, have invented a new and useful Improvement in Vent-Tubes for Storage Batteries, of which the following is a specification.
My invention relates to vent-tubes for storage-batteries and its object is to provide a simple and eifective means for permitting the escape of gases from the battery and preventing the escape of the liquid therefrom.
With this object in view my invention comprises essentially a vent-tube carrying a plunger so constructed and arranged that the impact of the liquid of the battery against the lower end thereof will cause the plunger torise and thereby close a vent in the top of the tube thus preventing the escape of the liquid through the vent.
One embodiment of my invention whereby the foregoing object' has been successfully accomplished is shown in the accompanying drawings in which- Figure l is a vertical section of a storagebattery provided with my improved venttube and Fig. 2 is a horizontal section taken on the line 22.
In that particular embodiment of my invention selected for more fully disclosing the principle thereof, 1 represents the battery casing containing the plates 2 and provided with the usual closure 3 through which the binding posts 4: pass in the usual manner.
5 represents the vent-tube which as shown is screw-threaded into the cover or closure of the battery-cell and to which-the cap 6 provided with the chamber 8 may be secured by threading the same thereto The upper wall of said capis provided with the vent 9 and the lower wall thereof is provided with one or more vents 10 herein shown as four in number. A plunger 11 which may be of soft gumfrubber, passes through an aperture in and is supported by the lower wall 7 of the cap 6. The plunger termlnates 1n means such as the head 13 arranged to close the vent 9 and at its lower end it is provided with the downwardly extending flaring portion, 12 which fits loosely in the tube and which is adapted to receive the impact of the liquid in the battery and thereby cause the plunger to rise and close the vent 9.
It will be understood of course that I do not limit myself to the exact arrangement of parts-shown in the accompanying drawings and that the said plunger may be of any suitable shape for accomplishing its intended purposes.
The vent-tube herein described is adapted especially for storage-batteries which are subject to shock and jar, such for instance as the ignition batteries carried by motor vehicles. The gas formed in the battery will readily escape through the vents 10 and 9 during normal conditions and when the mo tion of the liquid in the battery is sufliciently violent to cause the same to splash against the lower end of the plunger the impact will cause the plunger torise thereby temporarily closing the vent 9 and preventing the escape of the liquid while the gas which thus is prevented from escaping will have ample room for expansion in the chamber 8 and. tube 5.
I claim:
1. A storage-battery vent-tube provided with a vent in its upper end for the escape of gases from the battery and a plunger inclosed within said tube and constructed and arranged to rise and thereby close said vent by the impact of the liquid of the battery against said plunger.
2. A storage-battery vent-tube comprising in combination a cap having a chamber therein, said cap being secured to the outer end of said tube, the upper and lower walls of said chamber being provided with pas sage-ways, and a plunger passing through the lower wall of said chamber, said plunger having a head, arranged to close the passageway in the upper end of said chamber and being provided at its other end wlth a downwardly extending flaring portion inclosed within said tube and arranged to receive the impact of the liquid in the battery and thereby cause the plunger to rise.
3. A storage-battery vent-tube provided with a Vent in its upper end for the escape subscribed my heme this 29th day of Mch.
of gases from the battery, a plunge? inclosed 1909. Within said tube and means Where y the impact of the liquid ofthe battery against said MELCHER EKSTROMEB 5 plunger will cause the latter to rise and Wit s:
thereby close said vent. GEO, K. WOODWORTH, In testimony whereof, I have hereunto E. B. TOMLINSON.
