ELECTRODE FOR ELECTROLYTIC DECOMPOSITION APPARATUS.

To all whom it may concern-N Be it known that I, CARL'FREDRIK HOLM- BO'E, a subject of the King of Norway, residing at Villa Solheia, R-iis, near Christiania, Norway, have invented certain new and useful Improvements in Electrodes for Electrolytic Decomposition Apparatus; and'I do hereby declare the following to be a full, 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 accompanying drawings, and to letters or figures of reference marked "thereon, which form a part of this specification.

The present invention has for its object to provide an electrode for use in electrolytic decomposition apparatuses. Theelectrode is of the kind which is provided with substantially vertically disposed ribs but distinguishes from prior electrodes of this kind in that it is built up of ribs of sheet, material which" are spaced apart from one another by suitable intermediate spacing pieces.

- The invention is illustrated in the accompanying drawing which shows an electrode constructed in accordance with the inven tion.

Figure 1 of the drawing is a vertical sectional viewof a pair of electrodes suspended in the cover of an electrolytic cell.

Figure 2 isa horizontal top View partly in section oft'he same pair of electrodes.

In the example shown the electrodes have the shape of a lattice, thin sheet strips (3) of iron or other suitable material being .thrcaded upon a number of bolts The distance between the thin sheet strips \(3) is fixed by tubular spacers (2), which are threaded upon the bolts alternatelywith the sheet strips. provided with suitably dimensioned end pieces (4) threaded on the bolts 1 and which are pressed towards each other by means of nuts on the bolts.

The ends of the electrodes are Application filed July 23, 1924. Serial No. 727,659.

The current is supplied-to each electrode by means of a conductor 10 having an end portion formed into a sleeve 6 which is threaded onto one of the bolts 1 between two of the ribs 5 as shown in the drawing. lhis effects a good and reliable connection and also serves to reinforce the electrode.

The ribs may be placed opposite each 7 other (as shown at a) or in such a manner that the ribs of one electrode are staggered with respect to the ribs of the other electrode, as shown at 1).

Between the electrodes 3, 3 a diaphragm 9 is arranged as shown 'in the drawing, said diaphragm being attached to the cover 7, 8 of the electrolyzer.

Claims:

1. An electrode for electrolytic decomposition apparatus comprising aplurality of substantially vertical ribs of sheet material, spacers for spacing such ribs apart and means for binding said ribs and spacers together.

2. An electrode for electrolytic decomposition apparatus comprising a plurality of substantially vertical ribs of sheet material, spacers for spacing said ribs apart, and screw bolts for clamping together said ribs and spacers into a complete structure.

3. An electrode for electrolytic decomposition apparatus comprising a plurality of substantially vertical ribs of sheet material, spacers for spacing said ribs apart, a sleeve interposed between two adjacent ribs, a conductor electrically connected with said sleeve, and means for uniting the parts into a complete structure.

In testimony that I claim the foregoing as my. invention, l[ have signed my name in presence of two subscribing witnesses.

CARLFREDRIK HOLMBoE.

Witnesses ANGEUS BRUGGE, OLGA MI'iLLER.
