PARKFORD, 0F LOS ANGELES, GALIFORNIA.
MAGNETIC LAMP HOLDER. A
Application filed Apri120, 1920. Serial No, 375,373.
To all whom it may cof/wem.'
Be it known that I, HOWARD C. JENKINS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have-invented new and useful Improvements in Magnetic Lamp Holders, of which the following is a specification.
This invention is a magnetic lamp holder arranged to provide a protector fitting over an ordinary incandescent lamp, the protector being adjustably supported by a permanent magnet arranged for removably holding the protector and the lamp carried thereby upon any convenient metallic support.
lt is the object of the invention to provide a simple and inexpensive construction wherein the lamp protector may be swung to adjusted positions relative to the. supporting magnet and readily clamped in such ad- ,justed positions.
Further objects of the invention will be understood from the following description of the accompanying drawings in'which Figure 1 is a side elevation of the invention showing, by means of full lines and dotted lines, different adjusted positions of the lamp and its protector.
Fig. 2'is a section on the line 2--2 of Fi 1.
n the drawings the glass bulb of an ordinary incandescent lamp is shown at 1, th1s lamp being arranged to be incased 1n a protector having a base 2 and wires 3 mounted thereon in spaced relation and arranged to form a protecting casing fitting around the sides of the lamp. Base 2 surrounds the usual socket 1a that supports the lamp vbulb 1. The wires 3 may terminate in an annular member 4 positioned over the end of the lamp. The connection between the supporting means and this protecting casing for the lamp may comprise an end member, preferably, removably secured on the protecting casing and shown as comprismg radially eX- tending arms 5 having spring clip ends 6 adapted to be engaged over the edge of the annular' member 4 of the protecting casing for removably holding this end member in position. An internally threaded socket is provided upon this end member, preferably, at the center thereof as shown at 7.
The protecting casing, as thus described,
and the lamp carried thereby are arranged to p Specification of Letters Patent.
Patented Jan. 31, 1922.
be supported by a magnet adapted to be secured by magnetism to any suitable supporting surface. The magnet may be either an electro-magnet or a pennanentmagnet.
In the present embodiment of the invention the magnet is illustrated as a permanent magnet shown at 8, the supporting connection being, preferably, an adjustable connection between the magnet and the protectlng casingfor varying the position of the lamp and lts protecting casing relative to the magnet. This adjustable connection may comprise a rod 9 having threaded engagement in the socket 7 and provided'at its opposite end with a concave socket 10 in which a ball 11 upon the end of a supporting rod 12 is arranged to be clamped in adjusted positions. The rod 12 is supported by the magnet 8 which is, preferably, a usual horseshoe magnet having the base 8 and the arms 8 and 8b. forming the respective poles of the magnet. The. supporting rod 12is, preferably, connected to the base of the magnet as by the threaded connection 13.
A clamping collar 14 fits over the ball l1 and is held thereon by the flanged edge l5 of the collar, this collar bein arranged for threaded engagement with t e supporting rod 9 for clamping the ball 11 against the concave surface l0 of the supporting rod 9. This threaded connection is shown, at 15 the portion of the supporting rod 9 below said threaded connection being, preferably, enlarged as shown at 16 to provide a surface arranged to be grasped when tightening the clamping collar relative to the rod.
By the construction as thus dcribed it will be seen that the supporting rod 9 and the protecting casing and the lamp supported therein may be swung to various positions relative to the supporting rod 12, as clearly shown in dotted and full lines in Fig. 1, and the rod 9 may then be clamped in such adjusted positions by screwing the collar 14 down upon the rod 9, thereby clamping the ball of the 'supporting rod 12 between the concave surface 10 of the rod 9v and the flanged shoulder 15 of the clamping collar 14.
The lamp and its protecting casing having been adjusted relative to the magnet 8, the lamp holder may be supported from any convenient metallic support by placing the ends of the poles of the magnet against the ico metallic support so that the magnet and the lamp and its protecting casing are held against the support.
Various changes ma be made without departing from the spint of the invention as claimed.
What is claimed is:
1. A magnetic lamp holder comprising aL cage adapted to enclose the bulb of an electric lamp, a portion of which cage is adapted to encircle the lamp socket, a magnet, a connection from said magnet to the end of the cage opposite the end that engages the socket of the lamp, and a universal joint in the con nection between the magnet and cage.
2. The combination with la lamp socket of a lamp, a protector fitting over said lamp and socket, and a supporting magnet connected to said protector and projecting beyond the same opposite the lamp socket.
3. The combination with a lamp socket of a lamp, a protector fitting over said lamp and socket, a supporting magnet, a ball-andsocket joint connection between said magnet and lamp protector, a part of said ball-andsocket joint being adjustable soas to clamp another part of said joint for supporting the lamp in adjusted positions, said magnet projecting from the protector opposite the lamp socket.
4. A Alamp holder comprising a magnet, a lamp protector fitting over a lamp andsupported by said magnet, a removable end cap on said protector, and an adjustable connection between saidend cap and magnet for supporting said lamp in adjusted positions relative to said magnet.
In testimony whereof I have signed my name tov this specification.
HOWARD C. JENKINS.
