PATENT OFFICE.
ASSIGNOR TO THE UNITED SOCKET FOR INCANDESCENT ELECTRIC LAMPS.
SPECIFICATION forming part of Letters Patent No. 264,919, dated September 26, 1882. Application filed April 11, 1882. (No model.)
To all whom it 'may concern:
Be it known that I, RAYMOND F. BARNES, a citizen ot the United States, and a resident ot New York, in the county and State of New York, have invented certain new and useful Improvements in Sockets for Incandescent Electric Lamps, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the saine.
The subject of my invention is a combined holder and oircuitbreaker for incandescent electric lamps, arranged to be readily and easil y attached to the end of a pipe containing the conducting-wires, to a bracket, arm, or similar manner to obviate all danger of' deran gement or accident which might possibly occur from short-circuiting in holders where the conductors are partly exposed. For this purpose I have constructed a device consisting in the main ot'.a base containing terminal plates and a revolving holder containing contact points or springs, b oth the base and the holder being made ot' insulating material, the former being arranged for attach-l ment to a suitable support and the latter constructed or combined with retainingsprings to hold a lamp in place.
The special construction of' the holder which I have devised is illustrated in the accompanying drawings, where- Figure l illustrates a lamp in a holder constructed in accordance with my invention, a
portion of the globe ofthe lamp heilig cutaway. Fig2 is a central vertical section ot' the holder and switch, taken on the line x x in Fig.3. Fig. 3 is a plan view ot' the socket for the lamp; Fig. 4., a plan of the under side ot' the holder; Fig. 5, a detached view ot' the contact-springs on the holder, and Fig. 6 views in detail of the contact-plates ot' the base.
Similar letters of reference indicate corre sponding parts.
O represents a cylinder of insulating materialsuch as hard rubber or vulcanite. It is internally screw-threadedat both ends, the lower thread being formed for the purpose ot' mountingthe holder on a tube, bracket, or other support, (represented by D.)
Within the cylinder C fits a block of insulating material, B, the upper side ot' which is formed with two prominent portions, g', cut
vfer for this purpose the square on one side, as shown in Fig. (i. Upon the terminals of the circuit-wires c c, carried through the pipe or support D and `through perforations in the plug B". The cylinder U and plug B constitute the base, and should be xed, or at least incapable, under ordinary circumstances, ot' shitting their position.
In order that the holder may be readily turned While all the parts are securely held together, I have adopted the construction shown in Fig. 2, where B represents a plug enlarged at its lower end and screwthreaded above. To its enlarged end contact strips or springsjff are fixed, and Wires led up therefrom through perforations to contactplates E. A nutwF, is screwed into the cylinder O, and prevents the plug B' from being withdrawn.
A socket, B, is screwed to the upper end ot' plug i B. This socket contains the contactplates E, and anyvsuitable means for holding a lamp and maintaining the contact ofthe wires leading from the lamp with the platesI E. I prearrangement shownviz., a cup-shaped socket and springs b b, fixed thereto. In this case the lamps should have a ridge or bead at or near the end of the neck, which can be forced under the springs b, as shown in Fig. 2.
The action and manipulation ot' the holder, as thus described, will be well understood. By turning the part B the springs F are brought into contactwith platesg, and the lamp is thereby brought into circuit. The projections g should be of such shape that they will act as a ratchet in conjunction with the springsf, and so prevent the lamp from being turned in both directions. It results from this that the direction ofthe current through the lain pis reversed at every closing ofthe circuit.
By the above-described construction other important advantages are secured. i For in stance, the switch plugs or keys commonly employed are dispensed with, a good contact be tween the wires ofthe lamp and the switch-terminals is secured and maintained, and since the parts of the holder above designated as the cylinder G, the plugs B and B', and the socket B are to be made of an insulating inaterial-such as vulcanite-the conductors are entirely insulated and protected, and a short circuitor rupture ot' the wires cannot be eli'ccted by careless persons or external objectssuch as a loose wire.
The minor features may be in many ways modified in the construction of these devices Without ail'ectin g the main object which I have in view-viz., to produce a device for holding incandescent lamps, which may serve both as a holder and circuit-breaker, and which will entirely inclose and protect the conductingwires.
Having now described my I claim 'is- 1. The combination, with a stationary base having circuit-terminals, of a rotary incandescent lamp-holder having springs capable of being brought into and out of contact With the terminals of the base by thev rotation of the invention, what holder in one direction, the base and holder being both composed of insulating material and inclosing the conductors, substantially as and for the purpose set forth.
2. A holder for incandescent lamps, consisting of the combination of a cylinder, C, and plug B, containing circuit-terminals and coni stituting a base, with a lamp-socket, B, and rotary plug B', containing conductors and contact-strips capable of being brought into and out of contact with the terminals of the base by the rotation of the socket and plug, sub-
