DEVICE FOR CONDUCTING ELECTRICITY TO LAMPS, 84c.

SPEGIFIGATION forming part of Letters Eatent No. 541,121, dated June 18, 1895.

Application filed February 27, 1895- Serial No. 539,932- (No model.) Patented in England December 24, 1891, No. 22,542.

To all whom it may concern.-

Be it known that I, GEORGE FITZHARDINGE ROSE, china and glass dealer, a subject of the Queen of Great Britain and Ireland, residing at 175 Oxford Street, in the city of London, England,have invented certainimprovements in devices for conducting electricity to lamps or the like on dining-tables or on other analogous articles or places where it is desirable to employ concealed conductors, (for which I have, in conjunction with George Phillips, of 175 Oxford Street aforesaid, obtained a patent in Great Britain, No. 22,542, dated December 24, 1891,) of which the following is a specification.

This invention has forits object to provide means whereby devices for conducting electricity to lamps or the like on dining tables or on other analogous articles or placescan be applied so that the said devices are concealed, and so that there is no necessity to cut, or otherwise injure the table, mantel shelf, sideboard or the like to which the devices are applied.

According to this invention the conductors proper are formed of fiat strips of flexible conductive material (such as copper for instance) so that they present no objectionable projection when covered by atable cloth or the like. At the places where the lamp standards or the like are to be connected to the conductors there are secured pieces of conductive material, or contact making devices, through which the conducting strips can be passed, or which can be passed over the said strips, these pieces or devices being provided with a conductive spike or spikes. The said pieces or devices may be of non-conductive material and the spikes pass therethrough or be put in contact with a contact spring or the like, to make contact with the strips. The said spikes pass through a table cloth or the like, when it is covered over the table, or the like, and the conductivedevices upon it. To secure rigid ity of the devices there may be struts, or distance pieces or stretchers, connecting the aforesaid spiked pieces, or any two, or more,

.of them, that may be adjacent toeach other,

or the strips may be connected by such struts or distance pieces. The connection of the condoctors of the lamps to the aforesaid spikes is eifected by metal brushes, or webs, attached to the conductors of the lamp and readily penetrated by the spikes when pressed upon them. The spikes may be connected with the lamp and the metal brushes or webs with the strips if preferred. The aforesaid conductors Figure 1 of the accompanying drawings represents a top plan view of a table, sideboard, or the like, to which myinvention is applied. Figs. 2, 3, and 4 are detail views showing contact devices. Fig. 5 is a vertical section taken through the table and one of the lamp-standards arranged thereon, and Fig. 6 is a sectional view through the table and one of the contact devices.

Referring to the drawings, a are strips or ribbons of conductive material such as copper for example covered with insulating tape, or other materiah except at the parts cl, where the contacts for leading the current to the lamps are to be made. The said strips on are connected by the leads b, c from any suitable dynamo or other generator of electricity so that they constitute continuations of the said leads for completing the circuit through the lamps.

The devices for making contact consist of clips d.(shown inelevations at right angles to each other in Fig. 2) of vulcanite, or other insulating material, containing contact springs 61 electrically connected to spikes d by the metal pieces 61 so that when the said clips are passed over the bare parts of the outgoing and return leads constituted by the strips 0, they make electric contact with the said strips. The conductors e from, and to, the lamps are provided with contact devices (shown in vertical section and plan of under side in Fig. 3) containing metal wire net work or brushes e in electrical connection with the metal pins and plates e so that when the said network or brushes, is or are, pressed over the spikes d (as shown in Fig. 6), the circuit from the one lead to the other is established through the lamp.

In the drawings at Fig. l I have shown an arrangement for two lamps along the center, and one at each corner of the table or the like,

but there may be any other convenient ar rangement of the leads and placement of the lamps. In using the device the strips or leads V aare first placed on the table, or the like, and

5 the clips d are put in place on the said strips or leads and a table cloth,or like covering bein g placed over all, the spikes (1 project therethrough and the lamps are then placed in position and the wire work terminations, or

10 brushes e are pressed onto the said spikes d and the circuit through the lamp across the strips or leads is established. The strips or leads a should be as thin and fiat as may be,

so as to make as little projection as possible :5 beneath the table cloth. In the arrangement described the lamps are in multiple are, but they may bein series, if desired, by discontinuing the conductive material and making the contacts so that the lamp completes the 20 circuit across the discontinuations. If desired the spikes (1 may of course, be at the ends of the lamp conductors, as shown at the left hand ofFig. 4t and the wire work or brushes 6 be in the clips 61 which are placed on the :5 strips a and the spikes d be passed downthe table-cloth, or like covering, and 1', is the 3,5

lamp standard.

I claim- For electric lighting on dining tables, sideboards or other analogous places, flat conducting strips and contact devices consisting 4o of spikes and metal brushes or webs for connecting the lamps thereto, substantially as described. i

In testimony whereof I have signed my name to this specification in the presence of 45 two subscribing witnesses.
