Specification of Letters Patent.
Patented Jan. 25, il2ih Application filed November 14, 1918. Serial lto. 262,471.
To all whom it may concern Be it known that 1, CHARLES H. STULL, a
citizen of the United States; residing at Seat.- tle, in the county of Kin and State of Washington, have invented lectric-Light Supports, of which the following is a specification. 1 i
' invention relates to the mounting of an electric incandescent lamp and its shade or reflector in a way to absorb the shocks and vibrations to which the lamp is subjected in machine shops and other places and which tend to break the delicate filament. I also .provide for the adjustment of the lamp within its reflector to bring it into focus.
Figure 1, is a view in perspective of a construction embodying my invention;
Fig. 2, is a view of my invention in elevation applied to a two-piece lamp receptacle.
Fig. 3, is a view of my invention applied to a mogul lamp socket.
Fig. his in parta longitudinal sectional view of my intention applied to a reflector.
. Fig. 5, is a view of a modified form of my invention. i
The band 6 is adapted by means of the screw 7 to be clamped about the lamp socket part 8, (that is the part'containing the lamp grip) of a porcelain lamp socket or receptacle and thus serve as a lamp socket holding means. (While socket and receptacle as sometimes used signify difierent parts,-
herein they are used synonymously.) Resilient wires, preferably four in number, 9;
10, 11 and 12, all of which are similar in construction and preferably provided with a coil 13 are fixedly secured to said band 6' at one extremity and fixedly secured to a base piece let at the other. This base piece 14: is Secured to the threaded flange part 15 is held in place against said part 15 by 'a bushing-17, which in turn is held in place by nut 18. The threaded portion 19 of the partspring'can be made to contain within itself 1 oppositely directed forces which will operate to produce a steady illumination.
. adjoining parts.
/ and neutralize severe shocks and jars that may be transmitted through the supporting standard or bracket to the lamp. These wires are caused preferably to exert a laterally directed thrust relative to the band or holding means 6,, so that the oppositely disposed resilient members operate against each other and in this way effect the very important result of producing a very steady light without sacrificing the advantages of their resiliency. The great importance of this appears when it is remembered that the use of riveting hammers and other pneumatic devices for instance, produce a constant vibration and jar of the entire surrounding supports, and it is at the same time imperative that good illumination be available on account of the requisite fineness or accuracy necessary in connection with such work. This applies also to such operators of acetylene burners who may be engaged at work On Such operators, often in obscure positions, must follow precisely the prescribed markings for their cuttings in order to make proper fittings of required nicety. The great steadiness of light made possible under such conditions by my inven' tion increases greatly the ordinary working tors engaged in such construction.
When said shock-absorber is to be em? ployed in conjunction with a reflector, it is.
manifest that the socket can be adjusted to utilize practically the full reflecting powers of the reflector in one of two ways; first, the
i holding means 6 may be clamped near the edge 23 or the edge 24, and again the length of wires 9, 10, '11, and 12 may be made thermore, the design of lamp bulb, i. 6., whether a standard or stereopticon design of bulb, will affect the degree of utilization of the reflective power of the reflector. In one. or the other of these ways, it is manifest that the lamp may be placed to the best advantage relative the focal powers of the reflector. The reflector also serves in addition to localshorter or longer as thecase requires. Furmesses izing the light, as a protection against rain and weather.
lit is preferred to construct the resilient means in the form of wires rigidly fixed to the base, because such construction permits the wires to be so adjusted as to support the lamp at any desired angle.
Obviously, changes may be made in the forms. dimensions and arrangements of the parts of my invention without departing from the principle thereof, the above setting forth only a preferred form of embodiment. l or example. although I prefer the use of a plurality of resilient wires. manifestly many of the advantages of my invention may be secured by a single resilient wire supporter 21 made of very stiff or tightly coiled wire.
I claim:
1. A holder for an incandescent lamp comaforesaid base.
2. A holder for an incandescent lamp comprising a reflector-supporting base provided on its outer side with attachment devices for the external support, a socket-clamp adapted to grip the outside of the lamp socket at different points thereon, and resilient supporting wires connecting said clamp and the said supporting-base.
In witness whereof, I hereunto subscribe my name this 1st day of Nov., A. 1)., 1918.
CHARLES H. STULL.
