PROVISIONAL SPECIFICATION
Improvements in Apparatus for Working Railway Distant Signals,
and the like.
I, ANGELO FAHIE. of 9 Westland Row, Dublin in the County of Dublin,
Ireland; Consulting Engineer, do hereby declare the nature of this invention
which has been communicated to me by Ralph Stephen Glover of Jhansi, North
West Province India; Civil Engineer to be as follows:-
This invention has reference to improvements in and in relation to distant
signal levers, or any arrangement by means of which a chain may be gripped and
hauled in over (or under) a pulley, and has for its objects (1) to enable the usual
lever handle to be worked as a ratchet and thus pull in any required length of
chain (2) to admit of the sudden release of said chain and (3) while attaining these
two objects to admit of a balance weight, or other contrivance intended to take up
expansion, or slack in the chain acting freely.
The invention is also applicable where a rope or wire, or where any combination
of chain, rope or wire is used.
In carrying out my invention I mount on the ordinary lever frame, in a suitabie
position, a specially constructed pawl provided with a lug or lugs for the purposa
presently described.
This pawl is arranged in such a manner that from its own weight, or by means
a spring or other contrivance it will, when the lever handle is pulled over come
into position to grip the chain, and when the lever handle is thrown back it will
be lifted from engagement with the chain.
To the lever handle is pivoted a movable pawl to the heel of which is attached
arod carried vertically along the lever and provided with a hinged handle at its
free end by the operation of which the movable pawl is caused to engage and
disengage the chain. As thus constructed the action of my invention is briefly as
follows.
When the lever handle is pulled forward the movable pawl which it carries
engages and pulls the chain in, while meantime the stationary pawl comes into
engagement and holds the chain during the operation of putting back the lever
andle.
The lever handle is then again pulled over and another length of chain pulled
n, and this operation may be repeated until any length required is pulled in.
To release the chain the lever handle is thrown back to its normal position, in
etting to which, it comes in contact with the lug or lugs of the stationary pawl
nocking same over and thus disengaging the pawl whereupon the chain is
eleased, and is left to be acted on by the balance weight, or other contrivance for
aking up slack.

I, ANGELO FAHE of 9 Westland Row Dublin, in the County of Dublin;
Consulting Engineer--A communication from Ralph Stephen Glover of Jhansi,
North West Province, India; Civil Engineer-do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particula:ly
described and ascertained in and by the following statement:-
This invention has reference to improvements in and in relation to distant signal
levers, or any arrangement by means of which a chain may he gripped and hauled
nover (or under) a pulley, and has for its objects (1) to enable the usual lever
handle to be worked as a ratchet and thus pull in any required length of chain
(2) to admit of the sudden release of said chain, and, (3) while attaining these two
objects to admit of a balance weight, or other contrivance intended to take up
expansion or slack in the chain, acting freely.
The Invention is also applicable where a rope or wire, or where any combination
of chain, rope, or wire is used.
In carrying out my said Invention I mount on the ordinary lever frame in a
suitable position, a specially constructed pawl provided with a lug or lugs for the
purpose presently described.
This pawl is arranged in such a manner that from its own weight, or by means
of a spring or other contrivance it will, when the lever handle is pulled over come
into position to grip the chain, and when the lever handle is thrown back it will
be lifted from engagement with the chain.
To the lever handle is pivoted a movable pawl to the heel of which is attached
a rod carried vertically along the lever and provided with a hinged handle at its
free end by the operation of which the movable pawl is caused to engage and
disengage the chain.
The accompanying Drawings will enable my said Invention to be more readily
understood and carried into practice.
Fig. 1 shews in elevation the arrangement for working the ordinary hand
lever pawl in combination with the stationary pawl.
Fig. 2 is a side view of the stationary pawl detached (on a large scale), and,
Fig. 3, a front view of same.
A, is the lever handle to which the movable pawl K is pivoted. This pawl is
operated by the hinged handle B, which connects with the heel of pawl K..
P, is the stationery pawl provided with a lug or lugs L and fixed in a suitable
position in the frame.
The action of my Invention is obvious. When the lever A is pulled forward
the movable pawl K, engages and pulls the chain in, while meantime the stationery
pawl P comes into engagement and holds the chain during the operation of
putting back the lever handle.
The lever handle is then again pulled over and another length of chain pulled
in, and this operation may be repeated until any length of chain required is pulled
in.
To release the chain the lever handle is thrown back to its normal position, in
getting to which it comes in contact with lug or lugs L of the stationery pawl,
knocking same over and thus disengaging the pawl whereupon the chain is
released, and is left to be acted on by the balance weight, or other contrivance
for taking up slack.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
First. In apparatus for working distant signals or for hauling in chains, wire,
or rope under similar conditions, the use and application of a lever A and movable
pawl K in combination with a stationery pawl P arranged and operating in the
manner substantially as herein specified and illustrated by the accompanying
Drawings.
Second. The use and application of apparatus for the purpose of working distant
railway signals or for hauling in chains, wire, or rope, under similar conditions
substantially as herein described and illustrated in the accompanying Drawings.
