FRAME FOR BATTERY-ELECTRODES.

SPECIFICATION forming part of Letters Patent No. 722,946, dated March 1903- l T Application filed September 13, 1902. Serial No. 123,208- (llo model.)

To all whom, it may concern:

Be it known that I, HERBERT COTTRELL, of the city of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Frames for Battery- Electrodes, of which the following is a specification.

The object of my invention is to provide a frame for holding battery-plates, such as may be made of material to be made active in the battery, either molded or pressed in form or otherwise adapted to be held in a frame.

A further object is to hold sets of positive" and negative plates separate in a relatively fixed position and to provide for suspending the same in an electrolyte without a support at the bottom of the cell. To guard against short circuit between said plates if they should buckle or warp, separators of the ordinary form may be used,or non-conductive buttons may be interposed between the plates. Such adjuncts, however, are not essential parts of my invention.

My improvement consists in first cutting a blank of sheet material to produce a frame having openings cut out therefrom to correspond in form and dimensions to the electrode-plates to be held therein, and I stampcorrugations, both lateral and longitudinal, to give it strength, and to form suitable recesses to clip the said electrode plates holes are, pierced in a top extension thereof for use in clamping the parts together and for suspending the same. I fold this sheet upon a central longitudinal line, so that the opposite holes pierced in the top and the opposite openings for the electrodes may each correspond. The electrode-plates may then be set in the. proper place and cemented or otherwise electrically connected with the frame, and rivets or other means of clamping the frame together may be employed. To group sets of the said 7 frames together and to hold them separate from each other, I employ non-conductive plates made with vertical grooves recessed therein adapted to receive the edges of the said frames. Such plates are applied to both the front and back edges of a set of the said frames and are held firmly in place by any suitable means. Through the holes in the top extension of the frames a bolt is passed horizontally having thereon an eyebolt excorrugated portion of the frame.

tending vertically, also washers of dimensions to fill the space between said frames. Nuts upon the extremities of said horizontal bolt are used to clamp the set of frames and washers together in electrical contact. The vertical eyebolts extend upward through the cell-cover and also through a conductive spanner which bridges across the top of the cell and terminates in a threaded portion with lock-nuts, which serve to draw the set of frames firmly to the cell-cover and form the connecting-terminals.

In the accompanying drawings, which form part of this specification, Figure 1 shows perforated frame-plate flat. Fig. 2 is a view of Fig. 1 on the line X X to show corrugations. Fig. 3 is a vertical view. Fig. 4 is a plan of Fig. 3 on line X X. Fig. 5 is a top view.

In all of the views similar letters of reference refer to likeparts.

0. represents the b is the cir cular embossing, surrounding the holes in the top of the frame, by which it may be suspended. c is the eyebolt; d, the spannerplate; 6, the lock-nuts, which are also the connectors. f is the non-conductive grooved spacing-support. g is the electrode plates and frame. h is the cell-cover, and 'iis the horizontal clamping-bolt.

I wish it to be understood that 1 do not limit myself to the precise form of the oblong opening in the frame which receives and holds the electrode-plates g, for I could make the In Figs. 1 to 5, inclusive,

frame sash-like in form with numerous apertures to hold a corresponding number of electrode-plates without departing from my invention, nor do I limit myself to the precise form of'the spanner-plate d as shown.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. A holder for electrode-plates for reversible galvanic cells, comprising a frame of sheet material, doubled, to clip the electrode-plates in its fold; and having a top extension perforated to receive a bolt whereby theframe may be clamped, and from which it may be suspended substantially as shown and described and as and for the purposes set forth.

2. In a holder for electrode-plates for reversible galvanic cells; the combination of a doubled metallic sash, a lateral clamping- ICC bolt, a vertical eyebolt, and a spanner-plate I separate in a fixed position in the electrolyte; :o to supportthe said holder suspended, sub: 1 substantially as shown and described, and as stantially as shown and described, and as and and for the purposes set forth. for the purposes set forth. 'Signed this 11th day of September, 1902.

3. A reversible galvanic battery; comprising a set of sash-frames to carry electrodes; 1 HERBERT COTTRELL' and non-conductive vertically-grooved plates Witnesses: adapted to be adjusted centrally to the front HOWARD H. ECKERT, and back edges of said frames, to hold them i LOUIS A. SAYRE.
