Improvements in Signal Lamps for Railways and for other
Services.
We, WILLIAM HOUGHAM, of 39, Temple Row, Merchant, JOHN ROBERT
FULLER FLEMMING, of 113, Adderley Road, Saltley, Manufacturer, THOMAS
HISLOP, of 333, Aithur Street, Small Heath, Wire-worker, and WILLIAM
BARRETT, of 71, Arthur Road Saltley, Railway Guard, all in the City of
Birmingham, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements in signal lamps for railways and other
services, our object being to provide a more convenient method of adjusting the
signals than that employed with the lamps at present in ordinary use, and to so
construct and arrange the lamp as to permit of the ready renewal of the signal
glasses when required.
In carrying our invention into effect in one convenient manner, we form the
inner metal frame for carrying the red and green or other coloured glasses
independently of the head or top of the lamp, and we so arrange the interior of the
frame that the glasses can be readily withdrawn and replaced. We preferably
allow the bottom of the frame to rest upon the base of the lamp body, and we turn
or revolve the frame as required by means of a stern which passes out through a
slot or aperture in the lamp head. A handle or finger-piece is attached to the
outer end of the stem for convenience in manipulation, and also to serve as an
indicator as to the particular coloured glass or signal placed in front of the light.
The combined signalling handle and indicator is arranged in a convenient position
beneath the ordinary lamp handle attached to the head of the lamp, and in such a
manner that the signalling can be effected by the hand with which the lamp
is held.
The lamp body is fitted with an ordinary glass front, and the oil lamp itself is
secured within a slide, or in any ordinary manner at the base of the body. The
head or top is secured to the lamp body by hinged catches, or by other suitable
means.
In another method of applying our invention we mount the red and green or
other coloured glasses of the signal lamp upon separate frames of a circular or
other configuration, each frame being pivotted upon a plate or bracket secured to
the lamp head. A cam-like projecting piece is provided upon each frame suitable
for engagement by the inner end of an operating stem or lever projecting to the
exterior of the lamp. Thus when the operating stem or lever is moved in one
direction the red glass is brought into position in front of the light, and when
moved in the opposite direction the red glass is forced away from the light, and is
replaced by the green glass. The handle on the outer end of the stem or
lever is arranged to serve both as a handle and as an indicator as herein before
described.
We modify the arrangement of the inner frame or frames for carrying the
coloured glasses, and the position of the operating stem or lever, sometimes
causing it to project through the body of the famp instead of through the head or
top of the same, but in all cases we so arrange the parts that the lamp can
be held, and the signalling effected with one and the same hand.
We do not limit the application of our invention to any one particular form
or type of lamp, but employ it with lamps of varying designs or patterns,

service.

Improvements in Signal Lamps for Railways and for other
Services.
We, WILLIAM HOUGHAM, of 39 Temple Row, Merchant, JOHN ROBERT
FULLER FLEMMING, of 113 Adderley Road, Saltley, Manufacturer, THOMAS
HISLOP, of 333 Arthur Street, Small Heath, Wire-worker, and WILLIAM
BARRETT, of 71 Arthur Road, Saltley, Railway Guard, all in the City of
Birmingham, 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 consists of improvements in signal lamps for railways and other
services, our object being to provide a more convenient method of adjusting the
signals than that employed with the lamps at present in ordinary use, and to so
construct and arrange the lamp as to permit of the ready renewal of the signal
glasses when required.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to ;-
Figure 1 is a side elevation of a lamp constructed in accordance with our
invention and Figure 2 a plan of the same with the upper part removed.
Figure 3 is a front elevation of the lamp head and Figure 4 a plan of the same
with part of the handle removed.
Figure 5 is an elevation of the inner metal frame for carrying the coloured
glasses.
The same reference letters in the different views indicate the same parts.
In carrying our invention into effect in one convenient manner, we form the
inner metal frame A, for carrying the red and green or other coloured glasses,
independently of the head or top of the lamp, and provide slide grooves or guides
on the inner side of the frame in order that the glasses can be readily withdrawn
and replaced. We preferably allow the bottom of the frame to rest upon the base
of the lamp body B and we turn or revolve the frame as required by means of a
stem C which passes out through a slot or aperture in the lamp head D. A. handle
or finger-piece E is attached to the outer end of the stem C for convenience in
manipulation, and also to serve as an indicator as to the particular coloured glass
or signal placed in front of the light. The combined signalling handle and
indicator is arranged in a convenient position beneath the ordinary lamp handle F
attached to the head of the lamp, and in such manner that the signalling can be
effected by the hand with which the lamp is held.
We provide grooves or depressions such as e Figure 4 upon the upper end of the
lamp head, preferably upon a metallic boss or seating secured to the head, for the
reception of a stop lug such as E' formed with the finger piece E. These grooves
are arranged in such positions that when they are engaged by the stop lug El they
respectively indicate that the red, green, or white glass is locked in front of the
light. To adjust the signal the stem C must be raised sufficiently to lift the
lug E' from the groove and thus permit the frame to be turned or revolved.
The lamp body B is fitted with an ordinary glass front, and the oil lamp

page_text: itself is secured within a slide or in any ordinary manner at the base of the body.
The head D is secured to the lamp body by hinged catches, or by other suitable
means.
In another method of applying our invention we mount the red and green or
other coloured glasses of the signal lamp upon separate frames of a circular or
other configuration, each frame being pivotted upon a plate or bracket secured to
the lamp head. A cam-like projecting piece is provided upon each frame suitable
for engagement by the inner end of an operating stem or lever projecting to the
exterior of the lamp. Thus when the operating stem or lever is moved in one
direction the red glass is brought into position in front of the light, and when
moved in the opposite direction the red glass is forced away from the light, and is
replaced by the green glass. The handle on the outer end of the stem or
lever is arranged to serve both as a handle and as an indicator as hereinbefore
described.
We modify the arrangement of the inner frame or frames for carrying the
coloured glasses, and the position of the operating stem or lever, sometimes causing
it to project through the body of the lamp instead of through the head or top of
the same, but in all cases we so arrange the parts that the lamp can be held, and
the signalling effected with one and the same hand.
We do not limit the application of our invention to any one particular form
or type of lamp, but employ it with lamps of varying designs or patterns,
making such modifications as may be necessary in adaption to the required
service.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is ;—
1. A signal lamp for railways and other services having the coloured glasses 80
arranged as to permit of their ready adjustment by the hand with which the lamp
is held, substantially as described.
2. The construction of a signal lamp for railways and other services substantially
as and for the purposes described and as illustrated in the drawings.
