'non or New Yoan Our' invention consists in certain improve- I ments y,intheconstruction of covers. ,for the cells of r orage batteries, said invention reicularly to the improvement and yjplates of certain polarity) with said coveriwhereby-a tight yandystable joint. is formed between said vpost-and cover and that may-.beforined quickly and inexpen sively, theend that the top of the battery will beproofagainst leakage or the creeping outtofgacidrom the inside of the cell througl'itlie joints between said parts, all as will be hereinafter more fully described and claimed.y v

Referring to the accompan ing drawings, which are made a part liereo andon which similar reference characters indicate similar parts, Figure 1 is a sectional view throu h one corner of a storage battery showing t e parts Where the post of one plate connector is united with the cover, the cover being shown in section and the post in elevation.

Fig. 2, Fig. 3, Fig. 4, Fig. 5, and Fig. 6 are viewsshowing modified forms of the construction, the views being taken throu h the battery to'p on a line at right angles with the line on which the section shown in Fig. 1 is taken, and illustrating only the form o joint between the post and the top.

In said drawings the portion marked A represents the wall of the battery cell, B one of the buttery plates (either of the negative or positive set, as both sctsare similarly connected und similarly united); C a Wooden separator such as connnonijr interposed between the positive and negative plates of a battery; D a metal bar forming a. connector by which each of the plates of the polarity corresponding to the polarity of the plate B are integrally united; E the post integrally united to the connector and termed a plate connector post; and F the battery top.

It will be understood that these several ISIS.` partgcare of any well, j own or appropriata` 11 const'iuction and-arrangement, the construe:r tion illustrated being that of a common'type;l of storage battery. -The `plates of like, po\ i s f larity are alternately arranged withgsepa}.j60` 'rators C betweenthemf and.A all theA plates of: the. same polarity are united by la connectoxrf` D, and A'the connectors, are each provided with a post E; the construction in respectio` L each set of plates 'beinga `duplicate of the other, only' one of saidposts is," orA need" b -4 In said construction thecoverF isjforin with perforations lto .receive the .plate=con y nectoi posts, and each referably hasayra- 'l0`=,l cess around its outeren each of said` rfcrations preferably is taperedslightly, itstdi; anieter-near the top, oret point10, ;bci,ng` slightly'less than at the bottom or at point- 11.

top of the perforation `in thecover, as be `9,00v enlarged to fit closely into said recess and bind the post tightly to the cover, forming a j i secure and tight joint. This upsettin is done in the process of assembling an byl an appropriately formedtool heated andy 95, brought down over the top o' the face by= l i. i appropriate pressure (a relatively light pressure has been found sufficient) until the metal of the post is tirmly'- pressed into and against the recess in the cover and the collar 13 brought tightly against the under` face of said cover. The link 14 is attached to the top of the pest E in the usual manner, by lead-burning, or running fusible material 15 into the tapered recess around its top. A sealing compound may be used in the joint to increase the eficiency of the seal.

In Fig. 2 a similar construction is shown except that in lieu of a tapered recess at the top of the aperture inthe cover a recess is shown .having a. squarecorner.,

In' Fig. 3 is show'n'a' modification wherein the post aperture .in kthe cover is of uniform diameter from-'to ftdbottom andthe. top of the postis presse llt to form a ange overhanging said aperture'.

Fig. 5'shows aimodiiication similar to Fig. 4 except` that the collar of the post adapted to bear against the undery face of the coverfis omitted, and .Figft shows a modification similar to. Fig. 4 except that the projections 16 are formed oIiQthe sides of post adapted v'n-'thecove'r to prevent any l of course, that the y end o f thepost E so `astolform th V `a'. enlargement adapted togiitl 'sha 'edrreces's at the to'p ofr .rme any a "protingfourselves to any y Jection' or enlargement, rillustratedy being only a iii l.

Having thus` ful yl described our said invention whatwe: claim as new and desire to secure by Letters Patent is:

1. A istoragegb'attery comprising a cell cover .with a'plate-conne'ctor post extending through an aperture therein, said post being formed with anintegral 'enlar ed portion immediately adjacent the top o said cover closely impinging against saidcover to form a tight 'oint between said parts, substantially as set Orth.

`fitted withlnsaid aperture and formed with diameter toward its top and with an en-` 'fit into the enlarged portion at n. relation one` toV the ver i or.. overhang )mounted in said aperture correspondingly "and we onot esirev this process or any y Y l at'the top of said aperture, substantially asy 'nector -mounte construct, but one byv or creeping out, of the.

tially as set forth.

2. A storage battery comprising a cover formed with an aperture to receive the platef connector post, vthe top of said aperture being enlarged, and a plate-connector post an integral enlar ed portion fitting the enf' larged upper en of said aperture inthe` cover, su stantially as set forthffy 3.
