The best -Way known vtome at'pre'sent o' carrying out my' inventionA is to compressi, the'copper oxid upon its backing primato-the" :firing and to employ for said backing a massof4 finely divided, material made up1 into. aplastic mass as hereinafter-.more particn;.
larly described. For the finely divided maf -terial 'I-jxnayv use some earthy'material vor' groundpumice, from which latter substance I have' obtained good results.
' In .the accompanying drawings, Figure 1 is .1a. front elevationf' of a .form of plate constructed in accordance with my.1 nvention. Fig; 2 is' avertical transverse sectio'nthrough the same. '-Fig. 3 uis .av vertical-'transverse section of the-preferred form of'plate. In Fig, 1, the plate 1 iso the forni `monly .employed in 'batteri's in which .the
j' plate *of copper oid has .'beveled'edges-.to
and the sup ortp vvate'or plates at 3. v
In Fig. .B he laye of copper o'xdis shown appliedto .one v.sur ace only of the support :Plate-aj frialdad., and. compacted by pressen, par inst'ance, .0f, an earthy .material or pomme, vthepreferred procedure in constructing' the plate as -follows: The- Inateria1-feonsttut- 1 1 f over the earthy material in the.mold andv ing the backing is made 'up into a plastic mass by mixing the same with a sgmion of caustic soda or other-'suitable flux and`is spread in a layer of the desired thickness in a mold. l@ver this the layer 4of cpper oxid, made into a plastic mass in the usual .or any proper manner' is spread. Prefer! ably, in making such plastic 'mass `I employ the'usual solution of caustic soda vbut do not limit myself to the use of any particular solution.` This plastic mass is spread the two layers are' then compressed in a hydraulic press to compact them in the same way heretofore .adopted for making thev plate composed wholly of copper oxid.
' The plate thus constructed is then fired at 'material of the backing plate and in the layer of the copper oXid or in either )or both. .The same operation of firing ob'- viously also results in the usual solidication or hardening of the copper oXid itself such as is brought about inprevious prac- 4tice'when the plate 1s composed wholly vof copper oxid. Owing to this semi-fusion or union of the opposed surfaces of the mass of copper oXid together with the solidilca- 'tion and hardening of the copper oXid itself, there is little liability to disintegration or detachment of the copper oXid por? tionof the plate from its support plate or backing and which will therefore give very long 'service at small initial cost.
I do not limit myself tol any particular constitution of backing plate containing the fluxing material like caustic soda, but prefer tovemploy one composed of'some yearthy .-mate'rial that will itself flux' in the fire and become consolidated' or hardened thereby upon cooling.
It is plain 'that my improved plate re quire's much less copper oXid than previous plates but will nevertheless give practically the same amount of service and material for action in the battery.
While I have shown a flat plate or backing and "one that is imperforate, I do not limit myself to any particular form.
In place of the solution of caustic soda as a flux and binder, any other flux such as is used in pottery Work might be employed in making up the support portion of the compound plate.
What I claim as my invention is:
l. A battery plate comprising a layer of depolarizing material and a support therefor, said layer united by fusion to said support.
2. A battery plate comprising a layer of copper oXid and a support plate, the meeting surfaces whereof are fused together.
3. A battery plate comprising copper oXid and a backing of molded finely d'rvidedf material compressed and fused together on their meeting surfaces, as andfor the purpose described. A
4. A battery vplate comprising a .mass of copper oXid compressed and fused to a backing of compressedl and solidified material, as and for the purpose described.
5. A battery. plate comprising a backing plate made'of earthy material and a. surface layer of copper oXid united therewith., by fusion of material of thel meeting surfaces of the backing plate andA copper oXid layer.
6.`A battery plate consisting of a mass of copper 'oXid compressed and solidified upon and fused with a back or support comprising' lcompressed' and solidified earthy material, as and for the pur ose described.
7. A compound battery p ate consisting of copper oxid'and earthy materiel in two or more compressed and solidified coalescent layers.
8. A battery plate comprising copper oXid v and pumice in, compressed and 'solidified coalescent layers. as and for the purpose described. f
