PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supporting and Guiding the Wires
used for Actuating Signals upon Railways, and other Purposes
of the like kind.
1, JOHN FISHER, of Chindrass House, Matlock, in the County of Derby,
Gentleman, do hereby declare the nature of this invention to be as follows:-
-
In the Specification and drawings accompanying the same of Letters Patent
granted to me for " Improvements in apparatus for supporting and guiding the
wires used for actuating signals upon railways and other purposes of the like
kind, and for keeping such wires constantly stretched" dated September 2nd
A.D. 1892, and numbered 15782. I described and shewed several improved form.
of guide pullies, or apparatus for supporting and guiding the wires used for
actuating signals upon railways, and other purposes of the like kind, and my present
invention has for its object further improvements in such pullies and their supports,
by which they are rendered very simple, cheap, and easily adjusted and fixed in
any required position.
In order to put my invention in operation, I take a metal pulley grooved at its
circumference to receive the wire which it is intended to carry and guide. The
pulley has a central hole through which passes a screw upon which the pulley
turns freely, and the screw itself passes freely through the two sides of a bracket
preferably of cast iron, between which the pulley fits and turns. One of these
sides consists of a plate, at the lower end of which is a hole through which the
screw already mentioned passes, whilst its upper end has lateral ears through each
of which is a hole to receive somewhat similar screws. The edge of the plate is
preferably curved somewhat down instead of straight.
て
The upper parts of the two plates described are united together by a central
part somewhat wider than the edge of the pulley so that the latter revolves freely
between the side plates, such central part preferably extending laterally above the
screw holes last described and strengthening the plate in which they are made.
Inside and above the pulley, the lower side of the central part is formed with two
guides projecting downward at a sufficient distance apart, their lower rounded
edges holding down the wire which is supported and which passes between them
and the pulley, and preventing it from rising out of the groove round the latter.
The lower curved edges described may be cut away outside at the centre so as to
allow the wire to make as great an angle as possible in either direction, without
friction.
Or, instead of two downward projections as described a single central one,
directly above the pulley may be used.
°
The pulley being in its place upon the screw in the bracket, with the signal
wire which is to be supported passing above it and below the downward projections
described, the central screw upon which the pulley turns is screwed into a wooden
post or other support and the bracket being then adjusted so that the wire can
pass and move freely in the direction required, screws are also screwed into the
post or support through the other two holes in the back plate of the bracket,
and the pulley is then strongly and securely fixed exactly in the position
required.
The central boss of the pulley is preferably made somewhat wider than the
grooved edge, so that the latter may revolve between the plates of the bracket
without fear of contact with them.

page_text: The improved carrier is very simple, light, cheap, durable, and easily fixed and
adjusted, and by their use the free and safe working of the wire is secured, and
economy is attained.
The details of shape and proportions of the parts may be varied more or less
as may be found advisable in different circumstances.

Improvements in Apparatus for Supporting and Guiding the Wires
used for Actuating Signals upon Railways, and other Purposes
of the like kind.
I, JOHN FISHER, of Chindrass House, Matlock, in the County of Derby,
Gentleman, 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 and accompanying drawings, that is to say :-
In the Specification and drawings accompanying the same of Letters Patent
granted to me for "Improvements in apparatus for supporting and guiding the
wires used for actuating signals upon railways and other purposes of the like kind,
and for keeping such wires constantly stretched," dated September 2nd A.D. 1892,
and numbered 15782, I described and shewed several improved forms of guide
pullies or apparatus for supporting and guiding the wires used for actuating signals
upon railways, and other purposes of the like kind, and my present invention has
for its object further improvements in the said pulleys and their supports, by
which they are rendered very simple, cheap, and easily adjusted and fixed in any
required position.
The accompanying drawing is in illustration of my present invention, Figure 1
being a front view of the improved support and guide, Figure 2 a back view,
Figure 3 an end view, Figure 4 a view from below, and Figure 5 a vertical section
of the same.
له
In order to put my invention in operation, I take a metal pulley a grooved at
its circumference to receive the wire which it is intended to carry and guide.
The pulley has a central hole through which passes a screw b upon which the
pulley a turns freely, and the screw itself passes freely through the two sides C,
of a bracket preferably of cast iron, between which the pulley a fits and turns.
One of these sides c¹ consists of a plate, at the lower end of which is a hole
through which the screw already mentioned passes, whilst its upper end has
lateral ears d, d, through each of which is a hole to receive somewhat similar
screws. The upper parts of the two plates described are united together by a
central part somewhat wider than the edge of the pulley a so that the latter
revolves freely between the side plates, c, c', (as shewn in Figures 3 and 4), such
central part preferably extending laterally above the screw holes last described
and strengthening the plate in which they are made.
The edge of the bracket is curved preferably somewhat down instead of straight,
as shewn at e.
"
Inside and above the pulley a, the lower side of the central part f, is formed
with two guides g, g, projecting downward at a sufficient distance apart, their lower
rounded edges holding down the wire which is supported and which passes between
them and the pulley a, and preventing it from rising out of the groove round, the
latter. The lower, curved edges 9, 9, described may be cut away outside at their
centre so as to allow the wire to make as great an angle as possible in either
direction, without friction.

page_text: Or, instead of two downward projections as described a single central one,
directly above the centre of the pulley, may be used.
The pulley a being in its place upon the screw 6 in the bracket, with the signal
wire which is to be supported passing above it and below the downward projec-
tions 9, 9 described, the central screw 6 upon which the pulley turns as described,
is screwed into a wooden post or other support, and the bracket being then adjusted
so that the wire can pass and move freely in the direction required, screws are
also screwed into the post or support through the other two holes in the ears d, d
upon the back plate, of the bracket, and the pulley is then strongly and securely
fixed exactly in the position required.
The central boss of the pulley a is preferably made (as shewn) somewhat wider
than the grooved edge, so that the latter may revolve between the plates of the
bracket without fear of contact with them.
The improved carriers are very simple, light, cheap, durable, and easily fixed
and adjusted, and by their use the free and safe working of a wire is secured, and
economy is attained.
The details of shape and proportions of the parts may be varied more or less
as may be found advisable in different circumstances.
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 :-
1. In carriers for supporting and guiding the wires used for actuating signals
upon railways and other purposes of the like kind, the combination of the pulley a
turning upon a fixing screw b, the sides c, c¹, connecting part f, curved projecting
guides g, g, and ears d, d, having holes for fixing screws, substantially as described
and illustrated.
2. In the combination described and claimed in Claim 1, the substitution for the
two curved projecting guides 9, 9, of a single similar curved projecting guide
directly above the centre of the pulley, substantially as described.
