of this invention to be as follows:-
An appliance or apparatus consisting of two shafts placed transversely across and
under the rails and provided with and working in suitable metal bearings. The shaft
nearest the signal ("i.e." the "blocking" shaft) is provided with two chain-sheaves (and
may be provided with a third).
The relieving shaft (i.e. the shaft for causing the arm of signal to be lowered) may
be placed at any suitable distance. This shaft is provided with a chain-sheave.
These shafts are connected or coupled for working purposes by means of wire rope or
wire cordage and short chains passing over and secured to the chain-sheaves above
mentioned.
The second chain sheave on the "blocking shaft" is arranged for working the
arms of the signals by connections of short chains and wire cords. The automatic
working of these shafts &c. is arranged by means of two vertical levers (working in a
radius) to each shaft and which levers are operated upon by two small brackets or
arms on the inside of the guards of the Engine. These levers are arranged for easy
adjustment but firmly secured.
The connections of the two shafts are so arranged that the Engine of the train
passing the relieving shaft places the levers of the blocking shaft in position for the
following train.

JOHN BENNETT GUY 4 Newlands Street Liverpool lately of 3 Fairlight Terrace
Cheltenham 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 :-
An appliance or apparatus consisting of two shafts placed transversely across
& under the rails and provided with and working in suitable metal bearings. The
shaft nearest the signal ("i.e." the blocking shaft) is provided with 2 chain pulleys
(and may be provided with a third).
The relieving shaft (i.e. the shaft for lowering the arm) may be placed at any
suitable distance. This shaft is provided with a chain sheave. These shafts are
connected or coupled by means of a wire rope or cordage to the chain sheaves just
mentioned. The second chain sheave on the "blocking" shaft is arranged for working
the arms of the signals by connection of short chains & wire cords. The automatic
working of these shafts &c. is arranged by means of two vertical levers (each working
in a radius) to each shaft and which lovers are operated upon by two small brackets
or arms secured to the inside of the guards in front of the Engine. These levers are
arranged for easy adjustment to the required distance, but firmly secured.
The connections of the two shafts are so arranged that the Engine of the train
passing the relieving shaft places the levers of the blocking shaft in position to be
operated upon by the following train.

BBB plummer blocks for shafts to work in.
CCC vertical levers secured to transverse shafts.
D D D two chain or Va sheaves to receive chains or wire cordage.
E one similar sheave to receive chains or wire cordage.
F dotted lines showing rails of permanent way.
Sheet 3 shows the levers set for the train travelling from left to right and as soon
as the Engine has passed the shaft on the left the levers take positions shewn by the
dotted lines ; And when the Engine has passed the right-hand lever and shaft the
levers take positions shewn by strong lines; and the cord or wire leading from
the second sheave E on the blocking shaft has its both ends connected to a lever of
the signal and at each action of the levers on transverse shaft "blocks ;" or lowers, the
signal as the case may be.
Having now particularly described the nature of my Invention I claim
The general construction, combination and arrangement of the several and
respective parts or any two or more of them together constituting my improved
method of and apparatus for automatically working the signals on or connected
with Railways as herein before described and illustrated on drawings.
