SPECIFICATION formingpart of Reissued Letters Patent No. 1 1,968, dated February 18, 1902. Original No. 663,750, dated December 11. 1900. Application for reissue filed August 9, 1801- Berial No. 71,527.
DIVISION A.
To all wh01n it may concern:
Be it known that we, ERNEST GREIL and EMILE AUDIGER, citizens of the Republic of France, residing at 138 Fanbonrg Sr. llonor, Paris, France, have invented certain new and useful Improvements in Electric Contacts or Current-Taking Devices, (for which Letters Patent of the United States No. 663,750 were use in connection with translating appliancessuch as lamps, candlesticks, or candelabraplaced upon or secured to a table or other support.
It has heretofore been necessary with the means usually employed for taking the electric current to conduct to the foot of the appliance a small cable or other conducting device, which isfrequently the cause of -much inconvenience, as it encumbers the piece of furniture or other support upon which the appliance rests and renders these latter liable to be upset. I
In accordance with our invention we connect the electric conductor not with the translating device-for example, a lamp, candlestick, or candelabrum-but with the piece of furniture itself, and we place in one or more positions upon such piece of furniture or other support contacts or current-taking devices which possess the advantage of not presenting either a projection or a cavity when arranged in position.
In the drawings forming a part of this specification, Figure 1 represents in cross-section and in plans. portion of a support, as a table, upon which is mounted the fixed part of our device. Fig. 2 shows in section and in external elevation the intermediate connectingblock, which is arranged between the said fixed part and a socket forming a part of the translating device. Fig. 3, represents the socket in plain and in section. Fig. 4 shows a sectional elevation of the various parts when the illuminating device is arranged in operative position.
Referring to the drawings, wherein like letters of reference indicate corresponding parts throughout the several views, a indicates a fixed block of insulating material-'-- such as wood, ebonite, or the likein which are embedded two conducting pieces ormasses b b, constituted, in the mannerof the brushes employed in electrical apparatus, of a large number of metallic wires arranged in juxtaposition, or these conducting masses may consist of thin metal sheets, lead shot, sheettin, plumbago, &c. The block a is rigidly attached to the table or other piece of fur- V niture or support and is embedded therein in such manner as to be flush with the upper surface thereof, as are also the conducting pieces or masses b I). These .latter are connected at their lower portions at c c with.
electric conductors from a generator by means W of flexible wires. The generator and the wires connecting the conducting pieces or masses therewith are not shown, as they are not essential to an understanding of the invention. I) b are embedded in the'piece of furniture or other support and may be concealed by a =1 cloth or cover placed on the latter.
The reference-letters d d indicatea pair of conducting projections, which are adapted to penetrate or enter the conducting masses 1) b and while serving to conduct the current to place the translating or other illuminating. device in circuit serve also to secure or hold.
nection' with a contact shownas a strip of metal f, arranged at the bottom of a cavity The block a and the conducting masses In certain cases I g, formed in the portion of the connectingblock opposite to that in which the projection 'is situated, and the other projection (l is in metallic connection with a contactconsisting of a band of metal h, arranged upon the periphery and bottom of the connecting-block e. \Vhen the connecting-block e is placed .tend into a recess j, formed in the flanged portion 11 of the socket 'i and is connected to the said flange i by the binding-post j. The top of the socketi has extending therethrough a hollow plug 7:, which projects within the socket and has operating therein a springactuated pin 1. The top of the socket 11 is provided with an opening I, through which extends the leading-in wire P of, the illuminating device 'i', which is adapted to be connected to the plug it by means of the nut 1 The otherleading-in wire l ef the translating device is connected to the binding-postj When it is desired to render the apparatus operative, the cylindrical connecting-blocks is placed upon the fixed insnlating-block a, the projections d d engaging the metallic masses b'b'. Then upon the cylindrical connecting-block e is mounted the socket i of the base of the translating device. The current passes, on the one hand, for example, from the mass 12 to the projection (Z, and thence to band h and sleevej, lugj', and thence to the translating device, and, returning, from the illuminating device to the hollow plug it, pin 1, metallic strip f, projection d, and mass 1), thus completing the circuit; or it may take the other path from the mass 1) through the Having thus described our invention, what contacts on-said socket-piece adapted to engage the contacts of the connecting-block and suitably connected to the conductors leading to said translating device.
2. The combination ofa plurality of electric conducting masses adapted tobe connected respectively with the positive and negative poles of an electric generator and mounted in a table or other suitable support, of an insulatin g con uec-ting-block having conducting projections thereon adapted to penetrate said masses, contact devices, one embracing said block and the other seated in a recess in the upper end thereof, a socket in the base of a translating device adapted to receive said block, a sleeve'in said socket connected with one of the conductors leading to said trans:
'lating device and adapted to engage the contact device embracing said block, and a yieldin'gly-monnted contact on said socket, connected with the other conductor leading to said translating device and adapted to engage the contact device seated in the recess in said block. t
3. The combination of a support having penetrable electric conductors, an external cylindric insulating-block having two conducting proj 'ctions extending below its under Side, one adapted to enter each of said penetrablerconductors, and also having upon its exterior two separate electrical contacts in communication with said projections, and an internal cylindric part adapted to fit snugly "around and so engage firmly with said exter- ERNEST GREIL.
