A IELECTR'IQ-LIGHTFIXTURE;

forming part of letters I SPECIFICATION atent No. 530,343, dated December 4,1894.

Application filed May 24.1e9 1," are No. 512,284. (N5 model.)

To all whom it may concern.-

Be it known that I, HERMAN HoRN, a citi-i zen of the United States, residing in the city and county of Philadelphia, State of Pennsyl- Vania, have invented a new and useful Improvement in Electric-Light Fixtures, which I mprovement is fully set forth in thefollowmg specification and accompanying drawings. My nvention consists of improvements in electric light fixtures, which are more espe, cially designed to support a cluster of lights, the same being made 'of separable parts, whereby the light-supporting part, is convenient for removal, and the necessity forcutting the wires is avoided, the said parts being also readily replaceable without reu'n'i ting the wires, and provision is madefor readily replacing a broken shade, orfor making'other slrnple repairs without the] assistancefof a skilled electrician, all 'aswill be hereinafter setforth.

Figure 1 represents a side elevation of an electric light fixture, having a portion broken away, embodying my invention. Fig. 2 represents a bottom plan view of a portion of the stationary part of the same. Fig. 3 represents a section on line as, to, Fig. 2. Fig; 4 represents a plan view of the lower socket of the fixture, and Fig. 5 representsaplan view of the reflector, showing the lamp sockets in position.

Similar letters of reference indicate corresponding parts in the several figures. Referring to the drawings: A designates a hollow stem, the upper extremity of which is adapted to be suitably secured to any desired point, preferably the ceiling of a room. B designates a rosette for the top of the stem. C designates a holder for the shade D, the latter being held in place by means of the screws E. A

To the lower end of the stem A is suitably secured the, hollow head F, the open end of which is closed by a disk of porcelain G, which is held inplace by the screws H, the heads of which have another function to be hereinafter described.

To the outer portion of the porcelain disk G, are secured the brass plates J and K, by

and serveto conductthe electriccurrent to the said contact plate .La port-ion Not which is ofi-set, and is provided with the slight projection P. The plate K assists in holding fthe plate J against the disk G, the binding screw L and the screw Q a passing through preferably in a recess B in the disk G. The plates J are two in number, as are also the Wires M and the binding screws L, Fig. 3.

which is suitably attached the inverted cone shaped reflector T, which is preferably corrugated and also serves as a lamp holder,

S and also the lamp socketsB and the electrical connections therebetween, the rings or bushings U assisting to hold the lamp sockets in position and to give the fixtures a finished appearance.

; ,Theup'per'portion of the socket S is provided with a porcelain disk V, which is held in place by the-screws W, W, and has also the off-set contact plates X, which are provided with the holes Y, which receive the projections P, when the said parts are placedin juxtaposition, the plates Xbeing held in place and being provided with wires andbindi'ng screws, &c., in all respects similar to the construction shown in Fig. 3, said plates being somewhat elastic.

the top of the socket S, and A designates slots l therein, diametrically opposite each other, which are adapted to receive, and serve as a guide for the heads of the screws H.

The operation will now be apparent. i Assuming the parts to be in the position shown, suppose for any reason it is desired to take the fixture apart, the socket Sis turned until the heads of the screws in the fixed, portion contact pieces N being disengaged from the holes Y by this movement, and a pull downward separates the light-supporting part from the stem A, and a new shade may be placed out cutting any of the wires or, the employmeans of the binding screws L, the heads of which are in suitable contact with the wires M,

ment of skilled labor. To put the fixture together, the parts are placed in juxtaposition,

F reach the slots A,'the projections P on the in position, or repairs made if desired, withfwhich pass downwardly through the stem A,

both plates, the head of the screw Q resting S designates the socket of the fixture, to

said reflector serving toconceal said socket Z designates an annular enlargement near as above described, and turned till the projections P enter the holes Y, when the circuit is completed.

It will be evident that the number of lamps may be increased or diminished, and that the reflector may be secured to the socket S in any suitable manner. Within the reflector T are secured the electric lamp sockets B, the same thus being concealed from view from the outside, leaving only the light-giving lamps exposed to the reflecting power of the shade and reflector, thus increasing the volume of light and avoiding the formation of shadows.

It is obvious that the reflectorT may be of various shapes other than cone-shaped, as shown and it is also evident that other changes may be made by those skilled in the art which will be within the scope of my invention and I do not therefore desire to be limited to the exact constructions I have herein shown and described.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is.-

1. A stem, one end of which is adapted to be secured to some fixed point, the other end of which is detachably secured to a socket S the latter carrying a reflector which serves to support and conceal within itself the lamp sockets B and the electrical connections therefrom to said socket S, the above parts being combined substantially as described.

2. A stem having a hollow head, a disk secured therein, contact plates secured thereto, said plates being adapted to engage other contact plates secured to a similar disk in a socket, the latter being separable from the stem and being adapted to supporta reflector which also serves to support lamp sockets and.

electrical connections thereto, said parts being combined substantially as described.

3. A stem, a hollow head thereon, a disk secured therein, contact plates J suitably secured to said disk, said plates having studs or proj ections 1 a socket S having also a disk and err-set contact plates, the latter having openings to.receive said projections P, a reflector suitably attached to said socket, said reflector being adapted to serve as a support for electric lamps, and means for guiding and holding said socket in place, substantially as and for the purpose set forth.

4. A sectional electric light fixture having contact devices, and adapted to support several lamps, a removable socket portion having a reflector secured thereto, which is common to all of said lamps, and electrical connections supported by said socket within said reflector, said parts being combined substantially as described.

5. An electric light fixture having a part adapted to be held stationary in position, and a shade connected with said part, and another part removably connected with the former the removable part being provided with an inverted cone shaped reflector, and one or more electric lamps attached to the latter, said parts being combined substantially as described.

6. A sectional electric light fixture having a supporting device, an open top reflector secured to said supporting device, lamp sockets attached to the interior of said reflector, and electrical connections thereto, concealed by said reflector, the latter also concealing said sockets, said parts being combined substantially as described.

-7. In a sectional electric light fixture, an immovable portion adapted to support a shade, and another portion removably connected with the former, said removable part being provided with an open top reflector, the latter being adapted to support and conceal lamp sockets, substantially as described.
