Year: 1884

page_text: PROVISIONAL SPECIFICATION.
1 GEORGE CLIFFE GAMBLE, Architect, of 4, Wellington Terrace, Laisterdyke,
Bradford, in the County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PIPE GUARDS FOR GAS SERVICE PIPES EMPLOYED IN
STREET LAMP POSTS to be as follows:-
"
My Invention relates to fitting on the top of the iron ring of the arm a metal,
earthenware, or glass cap the top of which is passed over the gas service pipe and
thereby prevents rain and the atmosphere acting on the pipe and wearing the same
away; the guard is made with a tubular conical top and is fitted, near the top
part of the pipe, only suflicient room being left on the supply pipe to allow of
screwing on the gas tap in which is fitted the gas burner. On the side of the
outside diameter of the guard holos are made for ventilation and to allow of any
escape of gas.

page_text: I GEORGE CLIFFE GAMBLE, Architect, of 4 Wellington Terrace, Laisterdyke,
Bradford, in the County of York do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PIPE GUARDS FOR GAS SERVICE PIPES EMPLOYED IN
STREET LAMP POSTS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The
My Invention relates to fitting on the top of the iron ring of the arm of a lamp
post a metal, earthenware or glass cap the top of which is passed over the gas
service pipe or may be screwed or otherwise attached thereto and thereby prevents
rain and the atmosphere acting on the pipe and wearing the same away.
guard is made with a tubular conical top and is fitted near the top part of the
pipe, only sufficient room being left on the supply pipe to allow of a check-nut
being screwed on below the tap which regulates the supply of gas to the burner
which burner is screwed into the upper part or socket of this tap.
The tap is screwed onto the top of the upright service pipe and is prevented
from becoming unscrewed or working loose by tightening up the check nut
herein before mentioned. The guard may be screwed tight to the gas service pipe
and extends to the outer diameter of the top of the lamp post thereby turning off
any rain or other moisture that would otherwise run down the service pipe and
rust or corrode it. At the outer diameter of the pipe-guard holes are formed for
ventilation and to allow of the exit of any gas that may have accumulated inside
the lamp post.
In order that my Invention may be fully understood I will proceed to describe
the same by reference to the accompanying Drawing in which Figure 1, is a
vertical section of the upper portion of a street lamp post with my improvements
applied thereto.
Figure 2, is an elevation of the same.
Figure 3, is a plan of the upper portion of the lamp post showing the guard and
the arm of the post.
Figure 4. is a plan of the guard.
Similar letters represent similar parts in all the Figures.
A A, is the lamp post; B, the service pipe which has a thread cut thereon to
allow of it being firmly screwed into the check nut C and also into the cock D,
into the top socket of which is screwed the burner E. The guard shown at F,
rests at G, upon the upper surface of the ring of the arm El, or upon a flange cast
on the lamp post for that purpose or it may be made to overlap the top end of the
lamp post with the object of turning of rain or other moisture and keeping the
interior of the lamp post weatherproof. At the side of the pipe guard holes J, are
formed for ventilation to allow of the escape of moisture or of gas that may have
accumulated inside the lamp post.
1 do not confine myself to the exact form of lamp post hereinbefore described as
I can apply my improved pipe guard in a similar manner to square, octagonal or
other shaped posts.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed 1 declare that what
1 claim is :-
Providing the top part of the service pipe of street-lamps with a guard or cap
which extends to the outer diameter of the top of the lamp post for the purpose of

page_text: turning off water and other moisture accumulating thereon to provent thom
running down the pipe and thereby rusting or corroding it, and at the same time
to hold the pipe firmly in its place substantially as herein beforo described and
represented in the accompanying Drawing.
