MECHANISM FOR FORMING BATTERY-PLATES.

SPECIFIGATIQN forming part of Letters Patent No. 532,701, dated January 15, 1895. Application filed September 12, 1894- Serial No. 52 (N0 11105619 A To all whom it may concern:

Be it known that I, CHARLES J. REED, a citizen of the United States, residing at Philadelphia,in the county of Philadelphia and State of Pennsylvania, have made a new and useful Invention in 'Mechanism for Forming Battery-Plates, of which the following isa specification.

My invention has for its objects, first, the construction of rolled grooved electrodes or battery plates with stiffening ribs and connecting lugs or ears in completed form; second, the construction of electrodes or battery plates which shall be entirely symmetrical in form and possess an equal amount of active surface when prepared or formed; third, the preparation of electrodes or plates possessing all of the functions necessarily attributable to the products of the mechanism hereinafter described.

My invention will be fully understood by referringto the accompanying. drawings, in Which I Figure 1 represents a plan view of a pair of electrodes or plates as they appear after the lead or equivalent material from which they are formed has been passed through the machine and the forming cylinders or rolls have made one complete revolution. Fig. 2 represents an end view of the mechanism,illustrating in dotted lines a sheet of lead as it is being rolled. Fig. 3 is a vertical sectional view taken through the body of the machine on line 3-3, Fig. 2, the shafting and cog-gearing for driving the cylinders or rolls being shown in elevation. Fig. at is an end view and Fig. 5 an elevational view of the machine, said figures showing in detail those portions of the rolls which cut or trim the ends of the electrodes and the connecting or contacting lugs or ears.

In the construction of storage battery plates it has been customary heretofore to prepare the body portion of the plate and afterward to attach the stiffening ribs and the contacting or conducting lugs or ears which unite the independent plates together. My present invention is designed to overcome this difficulty and expense in construction and to make a plate of this general nature which shall be integral in form.

My invention will be fully understood by referring to the following detailed description of the drawings and to the especial features of novelty particularly pointed out in the claims at the end of this specification.

Referring first to Figs, 2, 3,4 and 5, A and B represent grooved steel cylinders or rolls which are sustained in adjustable journal bearings by axles S and S upon a rigid frame not shown, said axles being connected together by gear wheels G and G which cause them to rotate at the same speed under the action of properly applied power. These cylinders or rolls A and B are provided with grooves a a and b b which, however, do not extend entirely around them, said grooves being discontinued over extended fractional portions of the rolls on one side and over limited fractional portions thereof on the other side, the discontinuations being in each instance in the nature of depressions or spaces having the same radial distances from the axes of the rolls as the bottoms of the grooves.

K, K, K K K and K are cutters or knives which are situated in dove-tailed or equivalent grooves in the depressions or spaces, see Figs. 2 and 4, the edges of said knives being slightly below the outer portions of the grooves a a, b b, the location of said knives being such that when the rolls advance under the action of the gear wheels G and G, the knives K and K will be in alignment with each other as shown in Fig. 2, while under a further advancement the knives K and K will be in like position, the knives K and Kt assuming under like conditions the same position.

a a are trimming knives or cutters secured in the depression or groove of the roll A and near the opposite ends thereof by screws 8', s, s, and b b are corresponding trimming knives which are located at the outer ends of the like depressions of the roll B, their location upon that roll being such that the outer edges of the trimming knives a a will act like shears upon the inner edges of the corresponding trimming knives?) b. V

C C are trimming rings or disks secured by screws 8, s, s, s, to the opposite ends of the roll A and are of such external diameters that when in position they extend slightly past the too opposite ends of the roll B and thereby act as trimmers for dressing or trimming off the edges of the metal as it is rolled forward through the machine.

In Fig.1 is shown a pairof completed plates or electrodes P and I as they appear after the rolls have made one complete revolution, 0 a being the grooved orbody portions thereof, 19', 13 19 p the stiffening ribs at the opposite ends and L L, L L the lugs or ears which are afterward cut apart by a pair of shears at the medial line 13 p.

I will now describe the mode of operation of the apparatus.

The rolls A and B having been properly adjusted to the thickness it is desired to roll the grooved electrodes, sheet lead D of the required thickness and width is passed between them as shown in Fig. 2, the rolls moving under the action of properly applied power and the gear wheels G and G. See Figs. 2 and. 3. As the rolls advance the grooves a a and l) 1) cause the lead to assume the corrugated form shown at c c, Fig. 1, and the first depression or space seen immediately on the left of the knives K and K, Fig. 2, forms the stiffening rib 1), Fig. 1. As the rolls advance, therefore, the electrode I" with the grooves cis completed and the trimming disks C 0, Figs. 3 and 4, trim off the surplus lead which extends over either side of the roll B. Finally when the rolls reach such a position that the knives K and K assume the relation which now exists between the knives K and K, Fig. 2, the stiffening rib p is formed and the aforesaid knives sever the lead between the electrode P' and that portion of the lead sheet which immediately follows. As the rolls advance, the trimming knives a or acting like shears against the inner edges of the trimming knives b b, Fig. 5, cut out a blank sheet of lead and leave the lugs or cars L L, L L, Fig. 1, until the third set of knives K K reach a position similar to that of K and K, Fig. 2, when the blank sheet of lead is again severed by them and the stiff ening rib p of the electrode P formed. A further advancement of the rolls completes the electrode P and finally the knives K and K assume their original position forming the stiffening rib p. In like manner as the rolls advance, the electrodes are made in pairs and as they are forced out of the machine they may be severed at the medial line 19 p by a pair of shears or any analogous instrument.

I do not limit myself to the particular mechanism herein described for forming a completed rolled plate or electrode which shall be integral in all of its parts as I believe I am broadly entitled to claim mechanism for rolling such completed electrodes, andmy claims are generic as to this feature. It is also obvious that intermediate discontinuations of the grooves a a, b I) might be made in the rolls if desired for the purpose of making one, or more intermediate stiffening ribs similar to the end stiffening ribs p p 19 Should such be provided it is of course obvious that there would be no cutting knives like K K, the function of the grooves being to form the intermediate stiffening ribs alone. It is also obvious that instead of forming the grooves longitudinally in the plates P and I, the rolls might be provided with longitudinal ribs and depressions which would form the grooves laterally, the intermediate spaces and cutting knives together with the trimming knives being as hereinbefore described and as shown in the drawings. All such structures I deem as coming wholly within the scope of my claims hereinafter made.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A machine for forming battery plates from a sheet or strip of metal consisting of means for rolling grooves in the material, and additional means for forming stiffening ribs at the ends of each plate, in combination with means for cutting out a section of the material between each pair of plates as rolled whereby lugs or ears are made integral with the plates.

2.
