MARTIN ll. COLLOM, OF DENVER, COLORADO.
MAGNETIC ELECTRIC-LAMP HOLDER.
SPECIFICATION forming part of Letters Patent No. 551,364, dated December 17, 1895.
Application filed June 12, 1895. Serial No. 552,533. (No model.)
To all whom it may concern; I
Be it known that I, MARTIN II. OOLLOM, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented a certain new and useful device which I call a Magnetic Inca-11descent-Electric-Light Holder for Magnetic Surfaces; and I do 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to an improved device for suspending incandescent electric-light lamps to metallic surfaces, and the objects of my invention are, first,- to arrange in the sockets of incandescent electric lamps or to secure to their sockets in any convenient manner a magnet which is connected in circuit and provided with exposed polar surfaces arranged so as to be placed in contact with magnetic surfaces from which the light is sus pended by magnetic attraction.
M y invention is especially adaptable for us in basements of buildings containing machinery plants, in bank-Vaults and around steamboat, pumping and elevator machinery, &c., undergoing repairs, as it enables incandescent electric lamps to be suspended from any magnetic portion of a machine bed or parts, or from nail-heads, iron girders, iron rods, the. I attain these objects by the mechanism illustrated and described in the accompanying drawings and specification, in which.
Figure 1 represents a sectional elevation through the center of an incandescent-light socket embodying my invention. Fig. 2 represents a longitudinal elevation of an incandescent-light socket illustrating the inde pendent application of my invention to a complete socket.
Referring to Fig. 1, A designates a fragment of the lamp. B represents the plug thereof. 0 designates the lamp-plug-engaging ring of the socket, which is secured to an insulated base D. A central aperture through this base contains a conducting-piece F secured thereto by the screw F. The piece F is formed at one end to contact with the depending pin G of the plug. It also has a depending end II, which is provided with a v binding-screw I. A second con ducting-piece J is secured to the base by a screw J. This is also provided with a depending end K which carries a binding-screw L.
On bridge R of the magnet I form a hollow hub R, which I thread exteriorly to fit the pitch of threads in the ends of sockets adapted to be connected to chandeliers and electriclight fixtures which have threaded-tube connectin g ends. I connect the negative circuitwire T to the magnet and carry its terminal end S up through the hollow hub and secure it to the depending end H of the conductingpiece .I with its bindingscrew F. The positive-circuit wire U,'I carry up through the hollow hub. I connect it to the depending arm II of the conducting-piece F with its binding-screw. The circuit is thus complete through the lamp by wire II and through the magnet by wire T and arm V of the magnet, through the wire IV to the arm X of magnet and out through negative wire T.
To apply my magnet to any socket during the course of its manufacture it simply re quires that the casing be see ured to a portion of the outer shell of the socket or the employment of a casing in which J 2 and M are made integral, in which case it is onlynecessary to remove the outer shell of any socket and substitute the casing M for it.
In Fig. 2 Iillustrate the casing M and magnot secured by the threaded hub to the end of the outer shell of a socket 1. this socket 1 is provided with a hollow interiorly-threaded hub 3, adapted to fit the pipes IOC.
The cap 2 of net and casing to the socket.
of chandeliers in which the hub R of the magnet screws, and thereby secures the mag- I form on the casing M a projecting hollow hub at through which the wires pass into the casing to the magnet and lamp and I secure a non-conductive ring 5 to the interior surface of this hub adapting it to hold the circuit-wire from contact with said casing.
My invention is simple and inexpensive. I have illustrated the magnet connected in direct circuit or in series, but it might be preferable in some cases to run the wires direct to the lamp and shunt a portion of the current to the magnet.
lVhile I illustrate and describe aparticular arrangement and construction of the various elements which enter into the construction of the lamp and magnet I do not wish to be limited to them, but claim the right to use any and all arrangements by which an incandescent light can be attached. through the medium of a magnet to magnetic surfaces.
Having described my invention what I claim as new, and desire to secure by Letters Patent, is-
1. The combination with the lamp of the socket and the magnet having exposed magnetic pole surfaces.
2. The combination of the lamp and means for connecting it in circuit, of the casing M having the hub 4, the magnet P having exposed pole pieces, the non-conducting rings 0 and the cap N.
The combination with an incandescent electric light and socket of a magnet in circuit either forming a part of or connected to said socket, and having exposed pole surfaces adapted to contact with magnetic surfaces.
4. The combination with an incandescent electric light socket of a magnet in circuit therewith having magnetic exposed surfaces, and means for securing said magnet to said socket and for incasing the same.
5. The combination with the lamp and socket of a magnetic device in circuit therewith and adapted to magnetically suspend in candescent electric lights from magnetic surfaces.
6. The combination of thelamp, the socket and an electro magnet in circuit having its pole or poles exposed and adapted to contact with magnetic surfaces whereby said lamp and socket may be placed in contact with and by means of magnetic attraction may be adjustably and removablysuspended from magnetic surfaces.
7. In a magnetic device for temporarilysuspending incandescent electric lights from magnetic surfaces, the lamp socket, a magnet secured thereto in circuit therewith having exposed polar surfaces, a casing inclosing said magnet and secured to said socket and end cap secured to said casing through which the exposed polar surface extends.
In testimony whereof I affix my signature in presence of two witnesses.
MARTIN II. COLLOM.
