Description
PATENT OFFICE.
HENRI PIEPEB, OF LIEGE, BELGIUM.
HOLDER FOR INOANDESCENT LAMPS.
EJPECIFICATION forming part of Application filed June 11, 1885.
To all whom it may concern.-
Be it known that 1, HENRI PIEPER, a subject of the King of Belgium, and residing at Liege, in the Kingdom of Belgium, have invented a new Holder for Incandescent Lamps, for which I have obtained Letters Patent in Belgium, October 20, 1884, No. 66,647, of which the following is a specification.
The holder for incandescent lamps forming the subject of my invention consists of two main parts-via, a fixed insulating plug and a spiral of strong wire, forming a kind of nut, adapted to be screwed with one end on the said plug and to be attached with its other end to the base of the lamp, in combination with the requisite electric connections and with a contact-breaker formed by a shoulder on the spiral and a knob or binding-post on the plug, the said shoulder being arranged to be brought into or out of contact with the knob or post by turning the spiral on the plug.
. On the annexed sheet of drawings, Figures 1 and 2 are outside views of the holder with a lamp attached thereto, the spiral being shown in two different positions. Fig. 3 is a vertical section of the holder and the lamp-foot. Fig. 4 shows the plug in elevation, and Fig. 5in section on line 00 a',see11 from below. Fig. 6 represents the spiral detached from the plug and the lamp.
The plug a, which is adapted to be screwed to the arm or bracket designed to carry the lamp, is made of an insulating material-such as wood or ebouite. It is lower part with several screw-threads, a, corresponding with the windings of the spiral I), while its upper part, (6, forms a projecting collar. Into this collar is inserted a small binding-post, i, to which is attached the outer conducting-wire h. The other outer conducting-wire, g, is'carried to a screw, f, centrally inserted into the bottom of the plug and having its head slightly proj ecting therefrom.
For the purpose'of attaching the spiral to the base a of the lamp, the said base may be provided, like the lower part of the plug,with suitable screw-theads, on which the spiral is screwed. The portion of the base 6 then in contact with the spiral (preferably the surface of the screwthreads themselves) is made of metal, and with the conductive surprovided upon its Letters Patent No. 321,933, dated July 7, 1885.
(No model.) Patented in Belgium October 20, 1884,
face thus produced is connected the wire is from the interior of the lamp. The second lamp-wire, Z, is conducted to a metallic plate, m, fitted into the center of the base e, but so as to be insulated from the conductive surface of the screw-threads. When, under these conditions, theplug and the lamp are screwed together by means of the spiral, the plate m will come in contact with the screw f, and thereby establish electric connection between the outer wire, 9, and the lamp-wire Z, while the other lamp-wire, It, will be in like. connection with the spiral by the conductive surface of the screw-threads of the lamp-base.
For completing the circuit of the lamp, the upper end of the spiral is provided with a projection or shoulder, n, which, when the spiral is brought into the properposition on the plug a,will come in contact with the aforesaid binding-post 1', arranged to project to a sufificient amount from the lower surface of the collar of the plug. By slightly turning the spiral this contact will be broken again.
In order to maintain the spiral in the position imparted to it, the collar of the plug is fitted with two recesses. q and p, for the shoulder n to catch into, and the plug is without screw-threads on its middle part, so that the upper windings of the spiral may spring and press the shoulder a into the said recess. WVhen the shoulder a is in the recess q, which is by the side of the post 13, it will be in contact with i, (see Fig. 1,) and the circuit will be closed, whereas, when n is in the recess q, arranged at some distance from i, the circuit will be broken. (See Fig. 2.) Thus by slightly turning the spiral, together with the lamp, one way or the other by means of the handle 0 arranged for this purpose, the lamp may be lit or extinguished. Preferably,the turns of the spiral screwed on the lamp-base are connected together by a strip of metal, 0, in order to prevent them from springing.
On account of the elasticity of the connection between the lamp and the plug a, the
lamp is better adapted than otherwise to endure concussions.
I claim as my invention- A holder for electric incandescent lamps, comprising a plug, a, having screw-threads a, a wire spiral, b, fixed on the lamp-base e, and
adapted to be screwed on the threads of the In testimony whercoflhave signed my name plug, contaet'pieces f and m in connection reto this specification in the presence of two subspectively with the wires g and Z, means of scribing witnesses. electric conduction from the wire is to the spi- 5 ml, at binding-post, '2', connected with the wire HEN NI PIEPER.
