PROVISIONAL SPECIFICATION.
An Improved Method of and Means for Raising and Lowering
Lamps on Signal Posts.
I, FRANCIS GASCOIGNE LYNDE, of The Mosque, Ahmedabad, India, but at
present residing at 7 South Crescent, Bedford Place, London W.C. in the County
of Middlesex, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to an improved method of and means for raising and
lowering lamps on signal posts and is particularly applicable to railways, and
the objects of my improvements are to economise time and to avoid the danger
of accidents arising from mounting ladders which is now necessary when changing
and cleaning the lamps.
According to my invention I employ a pair of chains, which pass over a pair of
pulleys oue mounted near the top and the other near the bottom of the signal
post; one end of each of these chains is secured to an angle bracket which is free
to be moved up and down the signal post on suitable guides and the other ends of
the chains are secured to a balance weight.
The chain is moved to bring the angle bracket to the bottom of the post for
the lamp to be placed upon it after which the chain can be easily moved to
raise the bracket and lamp to the top of the post owing to the balance weight
which when the lamp is in its highest position may rest upon a bracket secured
to the signal post, to which the weight may be secured; a suitable catch may
be employed to hold the chain stationary when the lamp is removed to be cleaned
or repaired.

An Improved Method of and Means for Raising and Lowering
Lamps on Signal Posts.
1, FRANCIS GASCOIGNE LYNDE, of The Mosque, Ahmedabad, India, but at
present residing at 7 South Crescent, Bedford Place, London W.C., in the County
of Middlesex, Civil 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 :-
.
My invention relates to an improved method of and means for raising and
lowering lamps on signal posts and is particularly applicable to railways, and the
objects of my improvements are to economise time and to avoid the danger of
accidents arising from mounting ladders which is now necessary when lighting and
cleaning the lamps.
According to my invention I employ a pair of chains which pass over a pair of
pulleys one mounted near the top and the other near the bottom of the signal

page_text: post one end of each of these chains is secured to an angle bracket which is
free to be moved up and down the signal post on suitable guides and the other
euds of the chains are secured to a balance weight.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an elevation of a signal post fitted with my invention, and Figs. 2
and 3 are two detail views of the balance weight and bracket for supporting
the same.
In the drawings, a designates the signal post and two guide pulleys
mounted respectively near the top and bottom of the signal post; c is an angle
bracket which carries the lamp d and is fitted to slide on a vertical guide a¹ fixed
to the signal post; e is the top chain which is secured to the upper end of the
lamp bracket c, and passes over the pulley b and is fastened at the other end to
the balance weight f; e' is the bottom chain which is secured at one end to the
under side of the lamp bracket c and at the other end to the balance weight of and
passes under the guide pulley b'; g is a bracket fixed to the signal post to form a
support for the balance weight when the sliding bracket c with the lamp dis
raised into its position behind the spectacles ; i is a catch pivoted to the cheeks
of the bracket g which comes over a collar f' formed on the balance weight fand
prevents it from rising accidentally from the bracket g; k is a cleet or catch
secured to the signal post a, and by which the sliding bracket c can be secured
when the lamp d is removed for cleaning or repairs. The man in charge raises
or lowers the angle bracket by pulling the chain e and when the lamp d is in
position behind the spectacles the balance weight is secured by the self acting
catch i engaging the collar fand the weight may be further secured by passing
a padlock through an eye formed in the weight below the bracket g. The
chains e e¹ are connected adjustably to the balance weight by means of a bar/
with holes in it which passes through the weight and a pin m which connects
all together the pin being prevented from working out by means of a loose
collar n.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved method of raising and lowering lamps on signal posts by means
of a sliding bracket, flexible connections such as an endless chain and counter
balance weight substantially as herein set forth.
2. In combination, the sliding lamp bracket, chains and balance weight with
means for securing the same substantially as specified.
