, useful i'mpro'veinentsin electric contacts or current-taking devicesfor electric'appliance's, and more especially those intended for illnmi-' devices, as lamps andthe'likejand the ob- This invention relates to certain new and nating purposes.

The invention aims'to construct an electric contact or current-taking device adapted for main connection with electrical translating ject thereof is to connect the leading-in wires .or contacts ot'the device by a pair of con ducting projections with penetrable conduct? in'g-strips adapted to receive the conducting projections atjany point of their length and also suit-ably arranged :upon a table or other support insuch manner that a number of lamps or the like may be arranged in various relations side by side in at least two di rections transverse to one another to enable .the establishment of luminous letters or signs especially for advertising purposes. The coneach strip they make contact and the lampor other device is placed in circuit. Furtherducting-strips are intended to be connected to opposite terminals or source of electricity, so thaton thrusting the conducting projections of the bumper other device one into more, the projections serve to secure the lamp or other device in position upon the support.

A further object of the invention is to pro- :vide a novel arrangement whereby translating'devices, as lamps and-the like, maybe placed at various points and in various order along conductors, as will be described with reference to the accompanying drawings, in

' Figure 1 is a sectional elevation and plan of I. the connecting device, which is adapted to penetratethe conductors forcompleting the circuit and seen ring the lamps or other. illu minating device in position. Fig; 2 represents the top structure of a table or other support constructed in accordance with our invention and provided with a series of parallel conducting-strips. Referring to the drawings by reference-let.

ters, 0, indicates .a cylindrical connecting-'- block of'insulating material, which is provided with the conducting projections 12 I). These latter need not necessarily be'fixed to the cylindrical block a, but may be adapted directlyto the lamp or other translating device; The conducting projection'b is in metallic connection with a strip of metal 0, ar-

site'tothat in which the conducting projecjection's are situated. The other conducting projection'biis in metallic connection with a band of metal 6, arra'n ged upon the periphery of the block a. The strip .0 and bandc are contacts adapted to hem metallic connection with the leading-in wires or contacts of the lamps or other translating devices.

The reference-letter f denotes a top structure of a. table or other support which is formed-witha series of grooves, within which are lodged a number or series of parallel conducting-strips g, extending over the surface of the support to enable-the translating de-- vices to be arranged side by side in at least two directions transverse to one another. Upon thesurface of the table or other support thus provided is arranged a sheetof asranged at the bottom of a cavity d,- formed in the base of the connecting-block a op'pobestos material It and a cover'of india-r'ubber 11. The connections of the conductingstrips g-with the positive andnegative poles of the source of electricity are eflfected in any suitable manner, and it will of course be understood that at the extremities of the table the section of the conducting-strips g are covered with an insulated sheet. The conducting-strips are shown arranged parallel to one another, andthey may be arranged in various shapes. For example, they may consist of straight parallel bands of a certain length or parallel concentric circles, &c. thus enabling the translating device or lamp to be arranged loo v at any poi nt inthe length of the conductin transverse to one another.

\ The projectionsb bnot onlyfdrni a contact for illuminating a lamp or other device, but are of such length that they penetrate the conducting-strips, asbestos, and india-rubber cover and secure the lamps or other translating devices tothe table or other support. The metallic masses forming the conducting-strings intended for the conducting projections may be constructed of various materials to enable electrical communication with the projections and their penetration. The conducting masses may consist of metallic wires, thin metal sheel s,lead shot, sheettin, plumbago, the.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. Thecoinbination ofaplurality of electric parallel conducting masses laid at substaniially uniform distances apart in the grooves of a table or other support and constituting pairs, the whole number of said strips being connected alternately to the positive and nega tive poles of an electric generator, an insulating connecting-block, a pair of conducting projections secured thereto and adapted to penetrate two of. said masses, and separate contacts suitably connected to each of said projections.

2. In combinatiomaconnecting-block, penetrating conducting means attached to said block,and electric cond noting-strips arranged at substantially uniform distances apart, and com-posinganumber of pairs, and adapted to be in communication with a source of electrical supply, and arranged with the negative strips parallel with the positive strips, said strips adapted to receive throughout their length said penetrating means for forming an electrical circuit and securing said block thereto.

- table or other support, and adapted to baconnected to the positive and negativepoles of an electric generator, and arranged so that the positive strips will be parallel with the negative strips, a connecting-block, and penetrating conducting projections attached to said block for engaging said strips for forming an electrical circuit and securing said block thereto. l

it. In an electrical contactor current-taking device,penetrable conducting-strips arranged at substantially uniform distances apart over a large surface of a suitable support,- and means for penetrating said strips for forming an electrical circuit and securing thereto at any point throughout the length of any two,

a lamp or other illuminating device.

5. The combination with a support, of conducting masses carried thereby, and adapted to be connected, respectively, to the positive and negative poles of a source of electricity, said masses being spaced with substantial uniformityand sustaining a parallel relation, and adapted to have connection to a translating deviceat any point, and so arranged u pen the supportthat translating devices may be arranged side by side close together in at "least two directions transverse to one another at all portions of the support traversed by i said masses, and conducting projections to penetrate the masses and placethe translating device or devices in circuit.

6. The combination of a number of electric parallel conductors arranged without delineati'ng any design, adapted to be connected alternately to thepositive and negative poles of a source of electricity, and arranged upon a support in numbers sufficient, and near enough together to permit of electrictranslating devices being engaged close together ,andside by side with said conductors, lengthwise of said conductors, or side by side transversely of the length of said conductors, so that the'translating devices may be arranged to delineate letters, figures and other irregular forms, and conducting projections for penetrating said conductors to place the translating devices in circuit' v In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
