.-App1ication filed June 14,

One object of my invention is to provide a novel reinforcing structure for the upper parts of the side Walls of built-up or molded containers and especially those madeof rub- 1921. Serial No. 477,512.

sarily, has its ends leevelled as shown, while its side facemay have at its middle avertically-extending groove or recess 6 for'the passage of a'hold-down rod. The upper face her compound or equivalent material paror edge of the block 5 and a greater or less tic-ularly adapted for use in battery construction.

It is further desired to provide apractical, simple and inexpensive container structure forthe reception of a removable and replaceable type of handle which shall be securely held in place and prevented from movement up or down, the arrangement being such as to provide substantial support to receive and withstand lateral as well as vertical stresses on the handle.

, Another object of my invention is toprovide a novel form of reinforcing and handlereceiving structure for the side wall' of a battery container, preferably acid-proof and adapted for the reception of a hold-down clamp and also permitting.theapplication 3f such clamps to properly mounted hanles.

These objects and other advantageous ends I attain as hereinafter set forth, reference ribs 4 projecting being had to the accompanying drawings, in which, I

Fig. 1 is a side-elevation of a molded battery container constructed in accordance with my invention and. showingmy improved handle as applied thereto.

Fig. 2 is an inverted horizontal section on the line 22,Fig. 1, and Figs. 3 and 4 are elevations showing modified forms of my invention.

In the above drawings 1 represents the bottom, 2- 2 the side walls and 3 one of thee'nd walls of an integrally molded or built-up battery container prefer ably made of hard rubber or equivalent electrolyte-proof in 's'ulating materi This container. preferably is made with 'nteg-ral plate-supportingwardly from its bottom 1 and has vulcanized to the upper and outer portions of its opposite end walls two relatively heavy reinforcing plates or blocks 5,

though obviously these may bemolded as a part of the container body or otherwise firmly attached to the same.

In the resent instance each of these blocks extends a ong the full length of the side wall handle has been mounted in; the, position portion of the top edge of the side wall 3 are indented or recessed asp indicated at 7 for the reception of the hook or clamp at the end of said hold-down rod and it is noted that this latter recess preferably is sloped inward- PHILADELPHIA, PENNSYLVANIA, COB- I 8,, which are oppositely inclined to the ver- 'tical so as to downwardly converge. These slots are designed to receive the hooked or transversely. extended ends 9 of the side members 10 of a handle 11 preferably made of lead-plated steel or other material inert toor protected from the electrolyteto be I used in the battery. 4 In the present instance the handle is made of relatively heavy wire or rod material which at the center of its top is bent downwardly or depressed as at 12 for the reception of a hold-down clamp in case it should be desired that this engage the handle rather .than the container itself. 'Bhe upper parts of the side portions of said handle, after extending downwardly for a short distance, are bent abruptly toward each other and are then again extended downwardly in substan tially parallel relation so as to form shoulders 13, their-freeends being bent, as shown, I

in opposite direction and, if desired their end faces oppositely bevelled. The itself is of more or less springy material and the shoulders 13 are so positloned as to lie handle transversely in and extend laterally beyond the open upper ends of the slots 8 when the 'supper portions or sides of the outturned'ends 9 of thehandle 'engage'the underside of the overhung'reinforcing member 5. Said shoulders thus limit the downward movement ofthe handle and coact with the ends 9 in limiting or preventing movement of the handle relatively 'to the container after the y to which it is applied and of' which it forms shown.

a part and it preferably, though not news,

In mountihg the handle its free endsi) may be entered respectively in. the upper ends of the slots 8 and as said handle is forced down, said ends are forced toward each other by the action of the sloping outer walls of said slots until finally when said ends 9 move out of the lower ends of said slots, they are free to spring apart into engagement with the under sides of the overhung supporting members 5 so as to prevent the withdrawal of the handle. As above noted, the shoulders 13 then prevent the further downward movement of said handle.

Inasmuch as the slots 8 are of substantially the same width as the wire of which the handle is made, there is little if any possibility of lateral movement of the latter. The shoulders 13 in addition to preventing downward movement of the handle beyond its desired position,; present relatively extended surfaces for engagement with the upper portions of the sides of the slots, thereby distributing over a considerable wall area any side,

stresses exerted upon the handle. The hantile is inexpensive and easy to manufacture and, in case it should become corroded or otherwise damaged in time, it can be quickly removed and a new one installed. The han dle-receiving structure is unaffected by the,

their lower ends laterally. as indicated at 8 to provide retaining shoulders or abutments' for the projecting ends. or heads 9 of the handle. This may then be mounted or removed as above described.

I may also form the container Wall, or the reinforcing block carried by it, with parallel slots or passages 8 as shown in Fig. 4, in which case the free ends of the handle are forced toward one another by means of a suitable tool to allow of entering said ends in the passages. down the full way, the ends spring outward and the end projections engage the shoulders at the bottom of the passages as in the other cases.

I claim:

1 A battery container having "a wall provided with oppositely-sloping passages, respectively, having retaining shoulders at their lower ends; with a handle of spring material having extremities movable through said passages and formed to engage said retaining shoulders of the container wall to retain the handles in place.

2. A battery container having a pair of oppositely sloping passages in at least one of its walls; with a handle having preformed projections at its lower ends mounted in said passa es. J

3. battery container having in its walls pairs of oppositely sloping passages formed with retaining shoulders with spring handles each having substantially parallel side members formed with laterally extended ends shaped to coact with the inclined walls of said passages when the side members of the handle are being forced therethrough.
