' STORAGE BATTERY PLATE AND METHOD or BUILDING.

APPLICATION FILED DEC. I b1917- 1 ,295, 365. Patent ed Feb. 25, 1919.

STOPJAGE-BATTEHJY PLATE AND I'JEETI'IDZB OE BUILDEH T '0 (ZZZ whom it may concecn:

iie it hno'ein that-we, dons M. Pmsnsou and Ann: 0. RETRUM, citizens of the United States, residing at Dawson, in the county of use qui Hide, State of Minnesota, have imiented cerctuin ne and useful Inn p iiiioments in Swings-Battery Plates and nlethods 035 Building; and We do hei'eby declui'e the owing to be afull, clear, and exact lesc'ription of the invention, such its wili. ena oie others skilled in the art to which apperteins to make and use the some;

invention relates to stem battery and the method of producing the physical structure of the same.

he invention has ps1 .iiculei' reference to 1 the type of plate including at base "from which radlnte thin leaves in spaced relation to receive between them the active material. 1 5 Well known it is highly desirable that the piste foiined i: sections and that the l v s be spaced continuously of their 1 1s and he void oi local condensetionsu it the object of the present invention to 0 Wide a method of producing the physical stcnctuie of the plate and to provide such vesultent plate as will insure these irslii e ettr-ibut =6 b an elevation of s, piste I e (F-Q8831; invention and divided sccti one a portion i sing b soltsi .gitudinel seo'ion on line showing the radiating; leaves, portion being ective vieW showing aftez formation of the :1 perspective View showing a of the plate and illustrgiting the manner in which tl leaves d icing the I "ivions of the first row i poition of the fox ere being formed, '4" is an end VlGW of a portion of e @d p ste in which channels are formed i L sewed 8 1E S13} 5 the leaves have been formed.

Jseftwing to drawings and. more per- Specification of Letters Patent Pgiig gt gd Egg 25 1919 Application filed December 11, 1551?. Serial No. 296,659.

e'ble condensation of the metal at the sides of scores and While. the scores in the several views are shown as being formed equidistant and parallel, they may have any desired arrangement either direct or meandering; so long; as they may be crossed in the next step 01 the process.

The next step of the/process is performed. with at cutting tool illustrated at '12 in Fig, of the drawings, which tool is drawn across a scored face of the plate while in? clined laterally with respect to the face so as to form and turn up the leaves 13. In this cutting oi? the plate to form the leaves, the tool 12 is entered into the plate to considerable depth equaling the entire depths of the resultant leaves and it is found that as the tool 12 progresses across the pliue serves to rip each leaf during the formation of the 'lQHIl KlBZW to the bottom of the cut made the tool. The is illustrated in of the drawings Where on the under side of til-e plate 10 e the iii-out upper side of the piste the 2.1 are shown of $lli1i1 depth While at 11 these scores are 5.1 n ri'oped to the bottom 13 of the cut v the plate when charged presents miss-arm surfaces with e consequent even -""o-ehen1icsl action, efunifotcm internal nee throu hout the superficialerees plate 'with better-y oii" high effieiency. I

1'11; 6 of the dzswings, them is illusplete in which channels 16 have been focmed by bodily TBmOVZLl of meted to the full depti of the subsequent leaf while in Fig. 7 13 illustrated the same section after 61 consequent buckling of i'zhe plate, Fus

the leaves have been formed by cutting with a tool in the same manner as described in connection with Fig. 4, it being noted that the ends of the sections of the leaves 17 overhang the channels 16 in the direction in which the cutting tool progressed.

What is claimed is:

1; The method of forming a storage bat- I tery plate which consists in cutting the plate With a resultant radiating leaf and tearing the leaf in the direction of the plate into sections.

2. The method of forming a storage battery plate which consists in cutting the. plate with a resultant radiating leaf and simultaneously tearing the leaf in the direction of the plate into sections.

3. The method of forming a storage battery plate which consists in scoring the plate and subsequently cutting the plate for a portion of its depth across the score in a manner to produce a radiating leaf and tear the latter from the bottom of the score to the base of the leaf.

In testimony whereof, we afiix our signatures in the presence of two witnesses.
