Specification of Letters Patent.

' Patented Jane 11,1907.

To all-7.071.071) it may concern:

Be it known that I, ALBERT S. MARTEN, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented and produced a new and original Improvement in High-Tension Electric Fixtures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to letters of reference marked there on, which form a part of this specification.

This inyention relates to electric light fiX- tures and more particularly to the supporting portion of fixtures em loyed for high tension electric lights, the o jects of the invention being to secure convenience in installing orrepairing the lights; to avoid the expense and inconvenience of a large number of alternate parts; to enable different connections to be easily and readil made; to save lahor, time and expense, ant to obtain other advantages and results, some of whichmay be referred to in connection with the description of the working parts.

The invention consists in the improved connection for high tension electric light fixtures, and in the arrangements and combinations of parts of the same, all substan tially as willbe hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 r ows in pers ective a street lamp minted in fixtures 0 my improved construction; F ig. 2 is a detail view of the thereon, as is common.

immediate lamp connection, and Fig. 3 is a vertical central section of the same upon line :c, Fig; 2;'Figs. {1 and 5 illustrate differentforms of my improved yoke, and Fig. 6 is a plan of the same.

In said drawin r, 10 indicates an electric light of the incani escent ty e adapted-to be operated upon-a circuit of iigh tension, the bulb being screwed into a neck-piece 1 1, having at its top resilient tongues 12, 13, adapted to be forced up through a assage 14,.in an insulating plate 15, into ho ding and conductive relation with other springs 16, 17, The said tongues 12, 13, are each in insulated connection with an end of; the lamp filament, and the springs 16, 17, each terminate in a binding post 18,

.19, respectively, to which the circuit Wires 20, 21, may be connected. The said insulat ing plate 15, is supported in horizontal position by a yoke 22, comprising a disk-like top.

23, and the arms 24, depending therefrom, at I diametricall opposite points. Said arms have their lower ends turned or bent inwardly toward each other to form feet 25, adapted to stand'upon the top of the plate 15, at opposite sidesof the central 0 eningthereof, and be secured in place by he ts 26, through said plate; -Said yoke thus aflords means forsupporting the plate 15, and the lamp mounted thereon, and to facilitate attachment of the yoke to a support, the said disk-like top 23, is centrally perforated as at 27, and preferably tapped or interiorly threaded to receive a correspondingly threaded connection ofstandard size. Obviously, however, the perforation of the top of the yoke may under some conditions be left to be tapped, as used, to any desired thread. But as above indicated, I prefer to tap the perforation to a standard size and thread, as shown, whereby the yoke is ready ,to receive a standard connection. While this connection may be the threaded end of a supporting rod, direct, either solid or tubular, I

prefer to employfja nip le 29, and which istubular to permifof eading wires therethrough if ever desired. Said nipple screws into the yoke as shown, and at its outer end is adapted to receive a coupling connecting it to the end of a supporting rod. This coupling may obviously be. of uniform diameter, connecting to a rod of the same size as the nipple, or it may be a reducing coupling 30, as shown inFigs. 4 and 5, and serving to connect either to a smaller rod 31 than the through the top half of the shade or reflector shown in Fig. 1, and the coupling screwed on thelainp fixture as distinguished.

the nipple clamps the said shade between itself and the top disk 23, of the yoke. 'lhe shade or reflector, with yoke and socketinside and ready at its top to exteriorly receive the supporting rodor bracket, can thus be supplied and handled as a single piece or entity. The upper surface of the disk-like top 23 of the yoke, will be noted, is conical or tapered to lit into the top of the shade or reflector from its inside and present a large frictional surface or seat, and the shade is thus clamped tightly and firmly in place.

Great convenience, and a large saving of time and labor in mounting lamps, is effected by my construction, and furthermore the in creased adaptability of the device to diliercnt conditions obviates the necessity of the workman carrying with him so many parts, and enables him to meet a wider range of conditions than heretofore.

Having thus described the invention, what I claim as new is 1. In an electric lamp fixture, the combi nation with exteriorlythreaded supporting means, of a yoke comprising a. centrally thickened. disk-like body part with a central opening clear through itself interiorlv threaded from top to bottom and adapted to receive into itself said exteriorlv threaded supporting means, arms depending from said body part outside said central opening, and a lamp socket "upported between said arms at their lower ends.

2. In an electric lamp fixture, the combil l l l l l l l the shade and screwed nation with (.Xlt-IlOllV tlu'eadcd supporting mcans and a conically beveled shade or rc llector apcrtured at its top, of a yoke comprisin a disk-likc body partwith a central opcninp; interior-1v threaded and adapted to receive into itself said cxteriorlv threaded supporting means, said body part having an outwardli beveled or conical top to lit. inside the said top of the shade and arms depending, from its periphery, and a lamp socket supported between said arms at their lower ends.

3. in an electric lamp lixture, the combination with a conically beveled shade or reflector aperturcd at its top, of a ,()l l comprising a disk-like body part with an interiorly threaded central opening, said body part having an. out 'ardl. v beveled or conical 5 top to lit inside the said top of the shade and arms depending from its periphery, a lamp socket supported between said arms at their lower ends, an exteriorly threaded nipple passing through said aperture of the top of into the said central interiorly threaded opening of the yoke, and a. sleeve screwed onto the top of said nipple and holding said shade against said yoke.

in testimony, that I claim the foregoing, l have hereunto set my hand this 25th day of November, 1903.
