PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Railway Fog Signals.
We, THOMAS JENKINS, trading as T. Jenkins and Company, of 14 and 15 Moland
Street, in the City of Birmingham, Manufacturer, and SAMUEL ILLIDGE, of
9 Belchers Lane, Small Heath, Birmingham aforesaid, Foreman of Works, do
hereby declare the nature of this invention to be as follows:--
This invention relates, in the one part, to the formation of the clips by means of
which fog signals are secured to the rails, and in another part, to improved means
for connecting the said signals to the rails, and in a third part, to carriers for the
detonating nipples, and in a still further part, to the formation of the reverse joints
by which the signals are scaled against the incursion of moisture or wet.
The clips in ordinary fog signals are made from lead strips, affixed either by
soldering the same to the middles of the undersides of the cases, or by closing
them between the joints. When soldered, the undersides of the cases stand away
from the rails, which is undesirable, and further, such cases are liable to skid along
and be pushed off the rails.
According to one form of this part of my invention, we cut clip bands from out
of the middle part of an outer or an under shell, or from out of a supplementary
tray-shaped shell.
The band clips may be either made by cutting two or more band clips, side by
side, from out of the middle, or the clips may be made from a single band, divided
at its middle.
In use, these band clips are cut or pierced from out of the bottom of the shell,
tray or carrier and are bent over of the head or tread of a rail.
In a further form of this part of our invention, we dispense with the use of clips,
and employ a tongue-shaped member, which is placed in the joints made by the
opposed ends of the rails, that is, there is directed from the underside of the case,
or from the tray or supplementary carrier shell, a tongue-piece, flap or plate,
which, when in use, is inserted down the joint between the opposed ends of the rails,
and is there held. The said tongue piece, plate or thin sheet metal member is
it may be
preferably cut out of and attached to the shell casing by a web, although
attached to the middle of the underside of a case by soldering, clipping, closing,
rivetting or other means.
To make the connection of the tongue tight or stiff, the said tongue is cross
cambered, so as to give the same any yielding breadth as may be desired, according
to the breadth of the joint.
Such tongue pieces may, if necessary, be used as supplementary securing devices
with the ordinary clips, and such tongue pieces may proceed from the edges or
middle of the shell of the case.
The tongue pieces may be made or cut-out double, and brought together alike
unto butterfly wings, and crossing the diameter of the shell, so that the metal
springs and accommodates itself to any width of joint.
Instead of the tongues being made from out of the shells of the cases, the
carrying trays may be made from soft or ductile metal, such as lead.
In two signals coupled in one, in which three shells are employed to form a case
with a double compartment, we propose that the middle shell should be made dish-
shaped or sunken, and with the middle of the bottom coming adjacent to the under

page_text: shell, so that a top and middle chamber is formed between the roof of the top shell
and the sinking in the middle shell, whilst the second chamber is formed by the
annular space enclosed between the bottom or base shell, and the outer parts of the
middle shell, the edges of which shells are closed, with the joints reversed.
Enclosed within the upper chamber is a narrow-based nipple carrier, whilst within
the lower one is a ring nipple carrier.
In the reverse joint, the edge of one of the outer shells is closed over the
boundary edge of the middle shell, whilst the houndary edge of the other outer
shell is close in a reverse direction over the turned in boundary edge of the other
outer shell.
The independent chambers may be made in the form of pockets crossing the
shell in a horizontal or vertical direction.
By our improvements, the depth of the cases may be greatly reduced, and by
providing the same with tongues which are inserted within the joints between the
ems of rails, the signals are prevented from being pushed off the metals by passing
trains.

To and in the manufacture of Kanway Fog Signals.
We, THOMAS JENKINS, trading as T. Jenkins and Company, of 14 and 15 Moland
Street in the City of Birmingham, Manufacturer, and SAMUEL ILLIDGE of
9 Belchers Lane, Small Heath, Birmingham aforesaid, Foreman of Works, 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, in the one part, to the formation of the clips by means
of which fog signals are secured to the rails and in another part, to improved means
for connecting the said signals to the rails.
The clips in ordinary fog signals are made from lead strips, affixed either by
soldering the same to the middles of the undersides of the cases, or by closing them
between the joints. When soldered, the undersides of the cases stand away from
the rails, which is undesirable, and further, snch cases are liable to skid along and
be pushed off the rails.
According to one form of this part of our invention, we cut clip bands from out
of the middle part of an outer or an under shell, or from out of a supplementary
tray-shaped carrier shell.
The band clips may be either made by cutting two or more band clips, side by
side, from out of the middle, or the clips may be made from a single band, divided
nt its middle.
In use, these band clips ent or pierced from out of the bottom of the shell, tray
or carrier are bent over the head or tread of a rail.
Figure 1 of the accompanying drawings represents a fog signal fitted within a
carrier tray provided with attachment clips made from the body of the same, thus
dispensing with clips soldered to the body of the case.
Figure 2 represents an elevation of the combined tray and clips.
Figure 3 represents a topside plan of the tray, with the clips closed or lying in
the same plane as the metal from which they are ent or pierced.
Figure 4 represents a section of the carrier clip separately.

page_text: Figure 5 shows the head of a rail, with the carrier clip attached thereto, with a
signal ready for use.
In Figures 1 to 5, a is a shallow tray, suitable for receiving a tight-fitting fog
signal b. a are flexible band clips, cut out from the metal of the bottom a³, of the
said tray, which may be made from tin, lead or any other material.
Instead of the signal &, being made to fit tightly within the tray, the boundary
edges a', may be closed over the flange, of the signal, (see Figure 6) hence an
additional closure against the incursion of wet or moisture.
Figure 6 represents a further form of our invention, in which the clips are made
from out of the same metal as the tray, but not from the middle. Figure 7 is a
section of the same taken through the band clips.
Figure 8 represents the blank from which the carrier is made, in plan and
edge view.
a is the body of the tray, and a', a² the clips.
Figure 9 represents another form of our improvements.
In this arrangement,
the clips are cut out side by side from the metal of the bottom of the tray.

opened, and Figure 11 is an underside plan of Figure 10.
is the tray, a³, the bottom, and a³, a the clips cut therefrom.
In a further form of our invention, we dispense with the use of clips, and employ
a tongue-shaped member, which is placed in the joints made by the opposed endis
of the rails, that is, there is directed from the underside of the case, or from the
tray or supplementary carrier shell, a tongue-piece, flap or plate, which, when in
use, is inserted down the joint between the opposed ends of the rails, and is there
held. The said tongue piece, plate or thin sheet metal member is preferably
cut out of and attached to the shell casing by a web, although it may be attached
to the middle of the underside of a case by soldering, clipping, closing, rivetting
or other means.
To make the connection of the tongue tight or stiff, the said tongue may be
cross cambered, so as to give the same any yielding breadth as may be desired,
according to the breadth of the joint.
Such tongue pieces may, if necessary, be used as supplementary securing devices
with the ordinary clips, and such tongue pieces may proceed from the edges or
middle of the shell of the ease.
The tongue pieces may be made or ent-out double, brought together alike unto
butterfly wings, and crossing the diameter of the shell, so that the metal springs
and accommodates itself to any width of joint.
Instead of the tongues being made from out of the shells of the cases, the
carrying trays may be made from soft or ductile metal, such as lead.
Figure 12 represents an underside plan of a fog-signal carrying tray provided
with stop or affixing tongues, which are inserted in the joint between the opposed
ends of two rails in order to prevent the signal being pushed off the metals before
it is exploded by the passing over it of a train.
Figure 13 represents a section of the same upon the dotted linee Figure 12,
Figure 14 is a vertical section on the dotted line A Figure 12, and Figure 15 is a
plan of the tray, showing the flaps closed, or before the laps are opened out to form
stop tongues.

when turned down, stop tongues for retaining the signal on a rail, and leaving gaps
or openings a in the bottom.
a' are the sides of the case which may be left creet, or they may be closed over
the flange of the case of the fog signal and made to fit tightly in the tray.
Figure 16 represents a fog signal carrier tray having a single stop tongue cut
out from its bottom.
Figure 17 is a front elevation of the tongue, with the tray in section.
Figure 18 represents an underside plan of Figure 16, and Figure 19 shows the
underside plan of the tray before the stop tongue is opened out.

page_text: Figure 20 shows in side view and 21 in topside plan how the carrier tray is
applied to the metals with the stop tongue passed between the joint between the
opposed end of two rails, so that it is impossible for the signal to be pushed away.
a is the tray, an tongue, with the middle parta, cambered, and with the tip a' made
straight, so as to give a lend into the joint. The sail tongue a' is cut from out of
the bottom a', of the tray, which preferably has sides a', and into which the case
of the fog signal tightly fits, as represented in dotted lines in Figure 16.
By having a piercing, formed by the cutting of the tongue from the bottom
of the tray, the signal is made to be reduced in height, as the metals come close up
to the underside of the signal.
Figure 22 represents a signal carrier tray provided both with stop tongues and
securing clips. Figure 23 is a transverse section of the same. Figure 24 is an
underside plan of Figure 23.
Figure 25 represents a plan of the carrier before the clips and stop tongue are
turned down and Figure 26 represents the carrier tray, with signal, when in use
upon a rail, whilst. Figure 27 represents a section upon the dotted line Figure 26.

Figure 33 is an eared tray or carrier, provided with securing clips either attached
thereto or cut out from the metal of the body of the same.
It will be understood that instead of the herein before described tongue stops
passing into the joints in the metals they may pass into slits made for their
reception in the body of the rail.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. In railway fog signals, providing the same with a supplementary case
or carrier tray having attachment clips for the securing of the same to the
metals.
Secondly. In railway fog signals, providing the same with a supplementary case
or carrier tray, having attachment or securing clips cut out from the metal thereof,
substantially as described and set forth in Figures 1 to 11.
