Improvements in Lamps.
I, GEORGE BRAY, of Blackman Lane, Leeds, in the County of York, Gas
Lighting Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to certain improvements in Letters Patent granted to me,
dated the 19th day of February 1891 and numbered 3040 for "Improvements in
the method of and apparatus for lighting and ventilating rooms," and has for its
object, the provision of means for holding the globe of the lamp.
In the Specification referred to the globe is supported by two fixed lugs and one
hinged, with a hand screw for adjustment. In practice I have found this method
of supporting the globe is not the best, as in the case of the breaking of the globe,
the fragments fall to the ground.
In order to overcome this drawback, 1 now propose to support the globe by the
main supply pipe in the manner as hereinafter described, making reference to the
accompanying drawings, in which
Fig. 1. represents a vertical sectional elevation through the bottom portion of a
lamp and globe, the main supply pipe and gas burners are not in section, and
Fig. 2. is a plan of a carrier for supporting the globe. .
The main supply gas pipe is indicated by the letter N. and attached thereto is
the body or expanded portion carrying the burners B₁ and prepared to receive a
vertical bar D. screwed for the reception of a lock nut E. on the top of a carrier F.
and an ornamental mut H. at the bottom.
On placing a globe O. on the lamp, it is, in the first instance, wholly supported
at the top by two fixed lugs P. and one hinged lug Pl the carrier F. at the bottom
is then placed on the vertical bar D. and retained by screwing the ornamental
nut H. on the end of vertical bar D. thus by these means, raising the globe O.
clear of the upper lugs P. and P1 as regards suspending same, but sufficiently
however in touch therewith to act as guides or steadiers; the carrier F. being finally
secured in the required position by screwing the top nut E tight against the carrier,
thus by these means, the globe O. is supported.
On unscrewing the ornamental nut H. at the bottom, the carrier F. can be taken
away, but in the act of unscrewing the same, the globe is lowered and suspended
at the top, by the two fixed lugs P. and one hinged adjustable lug P' and when it
is desired to remove the globe for any purpose, the adjustable screw S. is unscrewed
thus releasing the globe O. so that it can be detached from the lamp.
The products of combustion and the heated gases from the globe O. pass away
either up the inner shaft A. or outer shaft B. in the manner as described in the
before mentioned Specification.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The combination with the lamp of the parts forming the complete apparatus for
holding the globe O. arranged substantially in the manner as shown and described
and for the purpose as hereinbefore set forth.
Dated this 7th day of January 1892.
