HENRY S. MONTGOMERY AND HENRY A. TOBELMANN, AJO, ARIZGHAL ELECTROLYTIC STARTING-SHEET SUSPENDER.

Specification of Letters Patent.

Eatented Jane M. 191%.

Application filed November 13, 191?. Serial 150.2%,301.

To all whom it may concern:

Be it known that we, HENRY S. Moira comznY and HENRY A. TOBELMANN, both citizens of the Unit-ed States, and residents of Ajo, li'ma county, Arizona, have invented certain new and useful Improvements in Electrolytic Starting-Sheet Suspenders;,and we do hereby declare the following tobe afull. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ends of this loop and riveted or other-.

wise secured thereto. The loops, usually two to a sheet, suspend the sheet below the electrolyte level from bus bars. I

The sheet does not'build up at the edge between the loop ends; but. on the contrary,

is dissolved at a rate greater than the building up on the body of the sheet and on the outer surface of the loop ends, sothat the sheet drops off of the Suspender loops before sufficient metal has been deposited on it.

lVe have discovered that in order to maintain the loops and sheet connected, the ends or legs of the loops should be so connected to the sheet that there will be no metal of the sheet between the layers formed by the loop legs. so that at the point Where the loop legs are secured there will always be an equal area of the sheet on the opposite side thereof exposed to the. electrolyte.

In order to accomplish this the loop may be variously formed, and in order to more fully explain the nature of our invention reference will be made to the accompanying drawings. in which like parts are similarly designated, and in Which 'Figure 1 is an elevation, and

Fig. 2 is a side view of a loop having two' non-overlapping connecting ends.

Fig. 3 is an elevation of a like loop having three non-overlapping connecting surfaces.

4 is an elevation, and

Fig. 5 is a side View showingsingle thick nesseso'f the loop secured'to' each face and spaced apart.

Fig. 6 is another view of a loop formed of a single strip of metal folded on the bias so that the ends are spaced apart on opposite sides of the sheet.

As already stated, the manner of securing the loops to the sheet is innnateria-l, and it may he by rivets as shown. or the ends of' on them taking as is now 0115- the loops may have hooks into slots cut-in the sheet, tomary.

In the drawings 1 indicates a portion of the upper edge of the starting sheet. Referring to Figs. 1 and 2, the two ends of the loop 2 are broughttogether and a slit 3 made from the bottom-edge'upwardly about midway of the width.

of these superposed ends, 4, 5, are bent to lie on one side of the sheet 1, and the otherpair 6, 7, to lie on the other side of the sheet, as more clearly shown in Fig. 2. R1v ets 8 or other fastening means secure the ends to the sheet near its upper edge. It will thus.

be seen that there is always an. area, as as, on one side of the sheet exposed to the elecr trolyte and not covered by any portion of the loop. lhis area. builds up with the rest of the sheet. as does also the surface of the end 6. so that there is always a connection between the sheet and loop. On the other side of the sheet, opposite the end d'there is a like surface 01 directly exposed to the This .leaves' four ends to the loop, 4,6 and 6, 7. One pairelectrolyte. and it will be seenpfrom the I drawings that these do not overlap. I

Fig, 3 is similar to Fig. 2, but Wider, there being two cuts or slits 3 leaving three two parallel surfaces pair of ends, two pair being secured to one face of the sheet 1. and the middle pair secured to the other face. These pairs of ends may be increased at will with the Width of theloop used. a

Instead of placing two thicknesses of the 1 of the sheet and the other end It lies against and is secured to the opposite face of the sheet, but spaced from the end 10; so as to always expose one face of the sheet at the loop to the-electrolyte.

The operation is obvious from the above description. There is but little metal deposited between the loop ends at the upper edge of the sheet, point 7 but the loop ends secured to the sheet build up, as do also the opposite faces of the sheet exposed to the electrolyte and'indicated by :1 thus the loop and sheet will hold together until sufiicient deposit has accumulated.

We claim 1. An electrolytic starting sheet suspenderin which the ends of the Suspender loop are but spaced laterally to include no metal of the sheet between the surfaces of said ends contacting with the sheet. 4

3. An electrotvt ic starting sheet suspender in which the ends oi the suspender are slitlongitudinally and secured to opposite fares of the sheet to include no metal of the sheet between the surfaces of said ends contacting with the vsheet.

4. An electrolytic starting sheet suspender having slit ends, an end at one side and an end at the opposite side ot the strip being cut away, thereby securing but one thickness of non-overlapping suspended metal to opposite faces of the sheet.

In testimony that we claim the foregoing as our invention, we have signed our names hereto.
