THERMO-ELECTRIC BATTERY.
Specification of Letters Patent.
Patented Feb. 28, 1911.
Application led July 10, 1908. Serial No. 442,804.
To all whom it may concern:
Be it known that I, JOHANNES MARSCHALL, a subject of the German Emperor, and a 4resident of 198 Grossenhainerstrasse, Dresden, in the Empire of Germany, have in.- vented certain new and useful Improvements in Thermo-Electric Batteries, of which the following is a specication.
The subject matter of the present invention is an improved thermo-electric battery.
In thermo-electric batteries known hereto- `fore it was customary to make the cells of was not desirable.
- Now thc subject matter of the present invention is a thermo-electric battery in which the two constituents of the cells have almost exactly the same resistance. The construction of the present thermo-electric battery further has the advantage in one special constructional form that the individual cells are easily accessible without having to take apart the entire battery. Namely the sepa` rate cells have ring shaped parts withwhich they are pushed over the cylindrical surface of the heater. They can then be rotated around the axisof the heater and, be very conveniently brought in this manner into the required position for being repaired.
In order that the invention may be clearly understood, reference is made to the accompanying drawing in which one embodiment is represented by way of example, and in which:
F'gure l is a vertical section through the battery. Fig. 2 is a cross sectional elevation ofthe battery without the bath taken on the vertical center line of Fig. l, and Fig. 3 is a horizontal sedtion through the middle portion of Fig. 1.-'
Referring to the"diawing, the battery is made as follows: From an iron, nickel, German silver, or like plate an lannular member d having a correspondingly large shoulder c is stamped out, two small lugs 7.2, Z1, each having a hole through the same'iieing provided on cach shoulder, as is clearly; shown in the drawing. The manufacture of the individual cells is now continued as follows: Both surfaces of the connecting portion a between the shoulder and ring, the shoulder c and the lugs 7c and b of the part of the cell which has been stamped out are coated completely with a film of varnish Z (Fig. 3) enamel or l any other suitable insulating layer may also be used instead of varnish. The portions a then made electrically conducting again both back and front on the surface of the varnish by either graphite, a metallic powon the varnish. The lug b remains without this electrically conducting coat. The entire stamped part of the cell prepared in the manner indicated above is' then galvanied in an electrolytic bath and thereby provided with a coat m. The coat m however, is fleosited directly on the ring al without any ayer of varnish thereon. Here also the lug b remains free fromthe electrolytic deposit, so that the iron or the like of which the part consists remains clean and bright when the varnish is removed. In this manner a thermo-electric cell is produced, the Contact surfaces of which extend over the entire ring d. The portion a, which is made relatively short and having a large cross-sectional area, serves as conductor from the real thermo-electric. cell to its terminals, namely to the lugs c and The portion o which dips into an oil, petroleum or. like bath serves as cooling surface. The lugs lr and slanting in one direction are connected by bolts a in groups and connecting rings nl are located between the lugs 7c and b. The lugs ,701 and 51 sloping in the other direction are connected by bolts 0 in groups and connecting rings 01 are located between the lugs b1 and L1 whereby two sets of groups of lugs are obtained which slant in opposite directions. The heated contact of the metals is which rests on the heating pipe f which may be of iron for instance. The second metal, for instance copper, is directly produced on the ring d on its entire surface. The heated contactn 'between the two metals 4therefore 'rests on the entire heating'pipe f. In case said heating pipe f is a conductor an insulating layer f, for instance of thin asbestos sheeting is provided between said pipe f and the ring (l. The part or neck a below the annular member d is separated from the electrical conducting material thereon by a layerof varnish Z as above stated. The current iiows through both metals forming the parta which are insulated from each other, that is ,from theheated contact at (l through the one"`metal,' for instance iron, to the lug Z) on the annular member d, that is the ring and c and the lug lc, but not the lug b, are
der, tin-foil or sultid of silver being applied which is free from any coating and through 'y Cit produce connected by Wires es shown in the tiren/"ing,
copper produced thereon are in contitct vwith' each other. vin the first group the lug-et have their free metallic surfacesv While in the second' cup the lugs 7c show the copperl thereon.l 'tween both groeps ere then this .is equivalent to e direct contact of both metals anni there is the'coi contact.
Tie' thermoelectric cell according 'to the present construction has among others the advantage that the eel-celled colei pieces t" and ore cooled very inteneiveiy by the'portion c for they are part of sei.- portion c which is iocetecl'in the oil. bethtliet .is the cooling agent, and they are also protected Well from radiation from the source of heat. Namely the celie have been pushed bykmezins of the ringe onto e hot pipe7 the rings are completely coveredv frein the outside by a hoot insulating peciingor Geyer or In the drawing the heating pipe is. denoted Iby j", the iue Within the Seme by g, and the grate oy L, the latter being pro- Vide only if necessary when flirect tiring is tobe used and not Waste gases. The oil beth is denote by e". l v
As one aclventage es compared with' conetructions known heretofore it may also be mentioned that soldering is done away with7 because the seconci constituent ofthe coli iS attached electrolyticoily.,v golvenicelly or gelvanoplasticelly.
