DESlGN FOR A BATTERY-PLATE.

SPECIFICATION forming part of Design No. 31,368, dated August 8, 1899.

Application filed July 3,1899. Serial No. 722,764- Term of patent 7 years.

To all whom. it may cancer/t.-

Be it known that I, HENRY C. PORTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Design for Battery-Plates,of which the following is a specification.

My invention is illustrated in the accompa nying drawings, in which-- Figure 1 represents a perspective view of a battery-plate embodying my design. Fig. 2 is a detail elevation of a portion of said plate, and Fig. 3 is a sectional view on the line 3 3 of Fig. 2.

The essential feature of my design isa rectangular frame, the side bars of which are connected by a series of parallel bars spaced a distance apart slightly greater than the width of said bars, each of which bars is provided in its opposite inner faces (as shown, in its upper and lower faces) with substantially V-shaped grooves and a central web of a thickness equal to that of said bars extending from the top to the bottom bars of the rectangular frame between the grooved cross-bars.

Referring now to the drawings, the rectangular frame consists of the top and bottom bars A B and the side bars C, all of said bars being rectangular in cross-section and the side bars being somewhat longer than the top and bottom bars. Extending between the side bars of said frame is a series of parallel cross-bars D, spaced apart a distance slightly greater than the width of the bars, the thickness of the bars being equal to that of the bars A B and C of the rectangular frame. Each of the cross-bars D has formed in its opposite inner or upper and lower faces substantially V-shaped grooves E, the inclined walls of the grooves being substantially at an angle of forty-five degrees and extending from the outer side faces of the bars in opposite direction and meeting at the longitudinal center of the bars, the opposing inclined walls merging into each other on a curved line at their point of conjunction. This gives to the two parts of each bar, at each side of the vertical longitudinal center thereof, substantially a triangular cross-section, the two parts being united at the apexes thereof. The inner faces of the top and bottom bars A and B also have Vshaped grooves formed therein, substan tially corresponding with those in the crossbar. This disposition of the grooved crossbars and the grooved top and bottom bars, with the space between said bars and between said bars and the frame, gives a novel shape to the spaces thus formed, being so bstantially the shape of an irregular hexagon, two opposite sides thereof being longer than the others. Between each pair of cross-bars and between the end cross-bars and the end bars A B of the frame extends a web at the center of length of the bars and of a thickness corresponding to that of the bars, the series of webs giving the appearance of a continuous barat the center of the rectangular frame between the top and bottom bar thereof and giving to the openings in the frame the appearance of two rows of narrow rectangular openings.

My design gives to the battery-plate a characteristic and distinguishing appearance.

Having thus fullydescribed my invention, what I claim, and desire to secure by design Letters Patent, is

The design for a battery-plate, as herein shown and described.
