To ell whom it muy concern:

lie it known that l, (.lUsrAvE lllznssininn, {initiaen of` the Freneli 'epublid Aand resi- (lent of Paris, France, have invented certain new and useful inprovenients in 'llluininatinn'lod-ics, of which the following specilieation.

yllie present invention relates to an iin-v proved device for the construction of electric illuminating); bodies, such as signs, let ters, Words, lirul'es, ornaments and the like, for the purpose-ef obtaining at littleA expense very elegant illuminating bodies coinprisiugir a very great number of lainps of low voltage and adapted to Work with the ordinary current. The electric connections are arranged. so that the extinction of any one of the lamps does .not interfere with the proper Working 'of the other lamps,

lu the accompanying drawings a luminous sign, coiistrueted according' te the present invention shown by way of example.

Figure l is a front viewl of the saiueglli Q is a seetion drawn on a larger scale on line A-B' of Fig. l; Fig. 3 is a cross seetion on,

a larger scale; Fig; L represents avinodiication; Fig. 5 is a front view of Fig. 4.

The sign, ornament,'letter, figure, ete., to

be represented, is out out of a plate of insu lating material and said plate e has as many holes o as there are lamps required; the eap fi oit' each lamp being fixed in its hole 0. The holes o are enlarged at the rear ends and Vin said enlarged parts e Cups f with spiral springs y] are located.

According to the voltage E of the line and to the voltage g of the lamps which are used, said lamps are divided into groups,

the lamps being connected in each group in shuntand the groups being; connected in series upon plate o. lf N represents the total nun'ibeief lamps rf. which have to constitute the luininous sign, each group will line is supposed to be .of 112 volts and the lamps a. ol the noi-unil. voltage of ley volts. The sign comprising 28() lamps, said lamps Awill be dividedinlo 8 groups of larnps each. To put said groups in series, a eerv tain number of conducting,r plates t, ft2 to l are mounted upon the upper face of plate ai, said plates being separated by 'insulating spaces t, s, 97,' Q. Each plate it serves to @unification of Letters Patent. .Application filed January G. 1869.

carry the lanips of two groups, or 70 lan-ips for Wine-h purpose the plate liasholes Whieh correspond to the' holes c andv are 'threaded @responding to the thread of the 5i lamp-caps. rhe two end plates f1.5 and h' carry only the lamps of one group, or 35 lamps.4 llpon the lower surface of insulating plate o.. otherconducting yplates m to m* are arranged. which are separated by insu,

la ting spaces 037e', u and which serve as supv ports for' spiral springs which through the intermedia-ry of cups f insure the electric eonneetien of each lamp b. (SeeFig, 3.)

`The plates m serve each 'for 70 lamps' and they are arranged so that the, insulating spaces and n of plates k .L' and m do not c0- ineide but' alternate in such a manner that there arenever moreI than 35 lamps between two consecutive insulating spaces (see Fig.-

l). The current arrives, for example, by

the lower end platee', flows through the first group of lainpsbf, and so onearried by said plate, to be conducted by means rof the rst of the plates fm, .designated m into the lamps b2 of the seeond group, to flow through `the plate L to the lamps b3 of the third group and so on to llow'out of 'the apparatus through the last strip i. Thus, if the currentge'ts into one'group of lamps by means of a plate It it will getinte the tivo adjacent groups of lainps by means of .plate m.

lf a-'signboard is to be constructed, the sign to be formed can either be cut out of a plate of insulating material or it can Ybe composed of several parts, said parts being one insulating plate showing the lshape of the sign to be represented.

For certain purposes it Will be advantagenus to be able to easily take to pieces the illui'i'iinating body,` particularly if the same foi-ins long rods; inthis ease Vthe rod willl Thus a rod .or bar of any length can be formed by connecting the required number of elements. rho elements will pre'l'eraldy bel connected by 'means of t screw bolts z whichfare screwed through one section of insulating plateJc and into one of the platesv v lw'or 1 belonging to said section of insulatnation a late of insulating material which Ahas they e ape of the .sign to be represented pzate k and intothe 'section of the plate 'g/ or io respectively of theadjacent element. If the screw bolts z be ,jthus'arranged, the 'different elements will be connected in series.

It is evident` that With the improved illuminating vbi'dy very artistic luminous devices can be con- .vstructed; by using lamps of 10W voltage (Ll 'or'lO volts for ,examplel-and of one candlepower there will be obtained Withoutpany practical inconvenience, an eXtreme..d'1v1- lsion of thefluminous lintensity which. is at thesamg time very economical and very ad'- vantage us With'regard to the arustie effect.
