SPECIFICATION forming part'of Ressued Letters Patent No. 11,970, dated February 18, 1902.

Original No. 663,750, dated December 11,1900.. Application for reissue led August 9, 1901. Serial No. 71,529.

To all, whom it may concern:

-Be it known that we, ERNEST GREIL and EMILE AUDIGER, citizens of the'Republic of Patent of the United States No. 663,750 were granted us the 11th day of December, 1900, and which are surrendered for reissue in three y divisions or patents,) of whichthe following is a specification. t

This invention relates to certain new and useful improvements in electric contacts or current-taking devices for electric appliances, and more especially those intended for illuminating purposes.

The invention aims to construct an electric contact or current-taking device adapted for use lin connection with electrical translating devices, such as 'lamps and the'like;` and the objectv thereof is to connect-the leading-in wires of the translating` device or lamp by a pair of conducting projections with a pair of superposed penetrable conducting bands or sheets of suitable material arranged upon a table or other support. sheets are insulated from each other and connected to opposite terminalsy of a source of electricity, so that on thrusting the conducting projections of the translating device or lamp one into each sheet they makecontact and the t'ranslating'device or lamp is placed incircuit. v Furthermore, the conductingprojections secure the device in position to the table or other support.

A further object of the invention is to provide an arrangement enabling the placing of translatingdevices or lamps at various points and in various order within the capacity-of the conductors to enable the establishment of luminous letters or signs, especially for advertising purposes, as will be described with reference to the accompanying drawings, in Which- Figurel shows a sectional elevation of the connecting device which is adapted to pene- 1trate the conductors for completing the cir- The conducting- Y DIVISION C.

structure of a table or other support constructedin accordance with our invent-ion and y provided with conducting-sheets.

Referring to the drawings by reference-letters, a indicates the base of our connecting device, which is constructed of suitable insulating material and provided at its top with a cavity b. Secured to the bottom of the cavity b is a metallic contact-strip c, to which is connected the conducting projection d, whichV extends through the block a. Secured to the periphery of the block a is a metalliccontact f e, which also engages the bottom of the block a and has attached thereto the conducting projection f, whose conducting-surface is out of line with that of the conducting projection d and which has its upper portion insulated by means of the sheath g. The contacts c and e are adapted to be in metallic connection with the` leading-in wires or contactsof the translating device or lamp.

' The reference-letter h denotes the top structure of'a table or other support, whose surface is covered by a pair of conducting sheets or bands'ij, and between the said conducting sheets or bands 'ij is interposed a sheet of insulating material la. By this arrangement the conducting-sheets are formed of superposed bands or sheets separated by the'qinsulating sheet or layer k. It will of course be understood that at'the extremities of .the table the sections of the conducting-strips are suitably insulated.

Mounted u pon the conducting sheet or band v 4 i isa sheet of asbestos m or other suitablev material, and upon the said sheet of asbestos mis mounted a cover of india-rubber 'n or other suitable material.

The points of thel conducting projections df, these latter being disposed in different planes, as hereinbefore stated, `are adapted asbestos, and the conducting sheets or bands i j. The projection (Z'penetrates only the 1 i -to penetrate the rubberl covering, sheet of IOC posed sheets or bands separated by au insulating layer of suitable material enables the translating device or lamp to be arranged upon any point ofthe conducting-sheets, and

5 by such an arrangement not only can the lamp be placed in any desired position upon the top structure of the table or other support, but it will enable the' arrangement of the translating devices `or lamps 'in various positions to form illuminated signs, letters, and designs. The projections d f serve also to secure the translating device or lamp to the table orv other support. The foregoing arrangement of conducting sheets 4or bands may be applied to partitions, floors, or the like, to which the translating devices or lamps are to be secured.

The conducting sheets or bands intended for the reception of the project-ions may be constructed of various materials to enable electrical communication by the penetration of the conducting projections. These sheets or bands may consist of metallic wires, thin metal sheets, lead shot, sheettin,vp1umba go, &c. l

e The conducting projections may beadapted directly to the base of the translating device] or lamp which it is desired to'place in circuit and forman integral portion of itsjsocket, as

this might be advantageous under certain conditions-as,-fortexample, in order to rapidly form a luminous sign.` j, 1

Having thus fully described our invention, what we desire to secure byLetters Patent is' 1. The combination with a plurality of electric conductors adapted to be connected respectively with the positive and negative poles of au electric generator, mounted one above the other on a table or Vother support and separated by a layer of insulating mate- 4c rial, and a layer of easly-penetrable insulating material on the top of said table or snp-- port above said conductors, of a connecting device-having projections thereon terminating at diierent levels and adapted 'to be inserted through said layer or penetrable insulating material to respectively engage said conductors, and insulating material on that portion of one of said projections which passes through theupper conductor.

2. The combination ofa support covered by conducting-sheets, one outside the other, an insulating-sheet between the conductingsheets, and means comprising two projecting contacts of diterent lengths and each adapted Y to penetrate one of the condncting-sheets'ltor placing a'translating device in circuit at any v point on the support, the longer of said contacts being electrically separatedifrom the outer conducting-sheet.

3. The combination of a support' covered by superimposed conductingfsheets, a layer of insulating material interposed between said sheets, and means comprising two downwardly-extendingcon tacts of different lengths and each adapted to penetrate one of the'conduct-ingsheets for placing a translating device in circuit at'any point of the support, the longer of said contacts being electrically separated from the upper conducting-sheet.

In testimony whereof we havemsigu'ed our names to this specification in the presence of two subscribing witnesses.`,
