LIGHT GLOBE HOLDER Filed Jan. 11, 1930 gwuwnto'c dam q Patented May 19, 1931 AMOS 0. DEETER, OF MINOT, NORTH DAKOTA LIGI-ITGLOBE HOLDER Application filed January 11, 1930. Serial No. 420,256.
The present invention relates to globe holders and more particularly to holders which are adapted for use in holding globes which are subjected to considerable expansion and contraction.
An object of this invention is to provide a globe holder which may be mounted in an upright, depending or horizontal position and which is particularly adapted for holding globes which are subjected to varying temperatures.
Another object of this invention is to provide in a globe holder means for permitting the globe and the holder to expand or con tract without exerting undue pressure on the globe and at the same time firmly holding the globe in desired position.
A further object of this invention is to provide a holder of this character which is so so constructed as to permit ready release of the globe for cleaning or replacing any of the component parts of the lighting structure.
The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the pres ent preferred embodiment, the same being illustrated in the accompanying drawings, wherein Figure 1 is a detail side elevation of a device constructed according to the preferred embodiment of this invention having a globe shown in fragmentary form mounted therein;
Figure 2 is a longitudinal section partly in detail of the device, and
Figure 3 is a detail top plan view of the device.
Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates the base portion of a light holder constructed according to the preferred embodiment of this invention.
The base portion 10 may be of any desired configuration and is preferably adapted to be mounted on an upright lamp-post or other vertical member.
It is, of course understood that the base 10 may be positioned in a horizontal or depending position, the position of the base depending upon the use to which the lamp holder is to be applied.
A body member 11 which is preferably of annular construction is adapted to be mounted upon the base 10. The base 10 is provided with an upstanding bolt or securing member 12 which is secured at the lower end thereof in the base and is provided with a threaded upper end portion 13.
A tubular member 14 is adapted to loosely engage about the upstanding post or securing member 12 and an electric socket, supporting member 15 is adapted to be threadably mounted on the upper end portion of the tubular member 14 and upstanding therefrom.
An electric socket 16 is secured by bolts 17 or the like, on the outstanding arms of the socket supporting member 15. A nut 18 threadably engages the threaded upper end portion of the securing member 12. The lower end of the tubular member 14 engages against the inner face of the body member 11 and when the nut 18 is tightened the tubular 7 member 14 will securely hold the body member 11 on the base or standard 10.
The body member 11 is preferably of substantially inverted frusto-conical construction which provides a concave inner face portion 19. A globe holding ring generally designated as 20 is secured to the upper edge portion of the body 11 and upstanding thererom.
The ring member 20 is preferably of split 7 The free half portion 24 of the ring member 20 is preferably hingedly secured at 25 to the ring 20 and is adapted to swing outwardly of the body member 11 so as to permit the flaring flange of the globe to be inserted upon the body.
A hinged locking member 26 may be mounted upon the ring member 20. The securing member 26 is provided with a hinged leaf member 27 and a pivoted securing hook 28 which is adapted to engage in a loop or outstanding member 29 which may be scoured to the free end of the hinged ring portion 24.
A handle or button member 30 may be mounted in the hinged ring member 2e adjacent the free end thereof so as to facilitate swinging the ring member 24 outwardly from V the body 11. The body member 11 is provided with a seat portion 31 at the upper end portion thereof and a pad or cushion member 32 may be loosely mounted on the seat 31 and is adapted to engage against the flaring flange 22 of the globe 23 so that when the flange expands the cushion member 32 will adequately take up any of the expansion so as not to subject the globe to undue pressure from the expansion and cause the globe to break.
A second ring or cushion member 33 is adapted to engage against the angularly inclined face portion 21 of the ring member 20 so as to take up any expansion or contraction of the globe when the globe is subjected to varying temperatures.
The cushion members 32 and 33 may be constructed of felt, rubber or any other cushioning material and are preferably constructed of material which will not deteriorate when subjected to moisture or the like.
The body member 11 may be provided with a plurality of openings 34 which are adapted to register with complementary openings 35 in the base portion so that suitable wires or the like may be extended therethrough and connected to the socket member 16.
If desired, the upstanding securing member 12 may be of tubular construction and the wires extended downwardly therethrough and through the base 10, in which case the openings 34 and 35 in the base may be eliminated.
If desired, a washer member 36 may be interposed between the inner face of the body member 11 and the lower end portion of the tubular member 14.
'Wh'ile the preferred embodiment of this invention has been constructed particularly for use in outdoor lighting fixtures and especially for street lighting fixtures where the lamp is usually placed in upright position, nevertheless, the fixture herein disclosed may be used in interiors or the like and may be mounted in any desired position, either up standing, depending, horizontal, or any angular position desired Elie fixture is particularly adapted for use where the lighting fixtures are subjected to varying temperatures and where the fixtures are subjected to high winds orthe like. In
the devices at present in use in order to properly secure the globes on the lighting standards it is necessary to lock them so tightly that when the globe expands or is subjected to excessive pressure through high winds or the like, the globes usually break.
With the use of the cushion members 32 and 33 which properly cushion the entire holding surfaces of the globe 23, when the globe is subjected to excessive pressure or varying temperatures the globe may expand or contract and at the same time the globe is firmly held against movement upon the fixture.
It is, of course, understood that various changes and modifications may be made in the design and construction of the preferred embodiment of this invention and that the body portion 11 and the base 10 may be const-ructed in various configurations, such changes and modifications being restricted only by the scope of the following claim.
V7 hat is claimed is A combined light socket and globe holder comprising a base, a globe holding body, a light socket supporting member, and securing means extending through the base and the body and engaging the member whereby to hold said member and said body on the base, said securing means comprising an elongated threaded bolt, a sleeve positioned about the bolt and engaging at one end against the inner surface of the body, a nut for said bolt, and a socket supporting member interposed between the nut and the bolt.
In testimony whereof I hereunto aflix my signature.
