Description

No. 888,951. PATENTED MAY 26, 1908. T. A. WILLARD.
STORAGE BATTERY PLATE. APPLICATION FILED MAR 29, 1907.
UNITED STATES PATENT OFFICE.
THEODORE A. WILLARD, OF CLEVELAND, OHIO, ASSIGNOR TO WILLARD STORAGE BATTERY COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF WEST VIRGINIA.
STORAGE-BATTERY PLATE.
Specification of Letters Patent.
Patented May 26, 1908.
To all whom it may concern.
Be it known that I, THEODORE A. W1L-' LARD, a citizen of the United States, residin at Cleveland, in the county of Ouyahoga an State of Ohio, have invented a certain newand useful Storage-Battery Plate, of which the following is a s ecification.
- The principal ob ect of the present invention is to prevent increase of the overall length of a one-piece plate such as is brought about by the rowth or expansion due to the formation and use of the plate.
Another'object of the invention is toprolon the useful life of the plate.
. transverse sectional view taken on the line 2-2, of Fig. 1.
.The plate consists of a blank all of which is of like metal, or in other words, of a onepiece blank. Upon the opposite faces of the lank there are rows or stripes 1, of ribs with flat spaces or stripes 2, between them. The ribs are shown to project outward beyond the flat arts 2. -3 are holes or openings arranged m the stripes or rows of projecting ribs and they extend clear through the late. As shown they are of oval form arranged with their longest axes crosswise of the rows of ribs and the openings in one row or stripe of ribs are arranged out of line with the openin s in the adjacent stripe or row of ribs. In
.this way the plate is not weakened. The
openings 3, afford space which, by receiving a the growth of the material, prevents an increase of overall length of the plate, and the oppositel disposed sets of ribs are expanslvely ba anced or in other words on each side of the plate the correspondin sets of ribs are so constructed and arrange that in use they expand or tend to grow equally. One, but not the only way of doing this is to make the ribs in each set identical in cross section. Furthermore under these conditions the tendency of plates to buckle is obviated. The ribs and material in the stripes between the o enings may grow'endwise and more or less the openings so that there are not created in the late undue strains while at the same time t e overall length of the plate does not increase and it is not subject to buckling, bending and twisting. In consequence of this the useful life of the plate is materially increased.
What I claim is:
1. A battery plateconsisting of a one-piece blank having rows or stripes of projecting ribs alternatln with rows or stripes of flat spaces arrange on opposite faces of the plate and havin oval openings arranged crosswise of the ribbed stripes and out of alinement with each other, substantially as described.
2. An integral battery plate consisting of a blank having on its opposite faces sets of projecting ribs alternating with unribbed spaces and the oppositely disposed sets of ribs being expansively balanced, and said.
plate having crosswise openin 's intermediately intercepting said ribs, substantially as described.
In testimony whereof I have hereunto signed my name in the presence of two witnesses.
THEODORE A. WILLARD.
