PROVISIONAL SPECIFICATION.
An Improved Combined Support for the Operating Rods and Wires of
Railway Points and Signalling Apparatus.
I, ARTHUR GEORGE EVANS, of "The Clift," Chippenham, in the County of
Wiltshire, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved combined travelling point rod roller or
support and wire pulley or support, for use in connection with railway signalling
apparatus, and consists in improvements in connection with and in addition to
the invention set forth in the Specification of Letters Patent granted to me
No. 24466 dated December 20/93; it is also applicable in connection with the
inventions set forth in the Specifications of Letters Patent granted to me
Nos 13004 A.D. 1891, 14304 A.D. 1897 and 16369 A.D). 1897.
In the above cited prior inventions side standards or supports are described
as having elongated top and bottom slots or paths for the trunnions of the tra-
velling rollers on which the point rod bears to revolve and travel along, and my
present invention consists in forming or providing preferably on the base of
such standards or supports an upward projection or side wall the top of which
extends over in a lateral direction and is connected to the roller standard thus
forming a hood or guard for the signal wire and also means for retaining it in
its proper working position with regard to the pulley wheel. The wire pulley
wheel is provided with trunnions which travel along paths formed in the roller
standard itself and in the additional projection or side wall; the path or paths
on which the pulley revolves and travels may either be in the form of an elongated
horizontal slot or recess in or a projecting rib or shelf on the roller standard
itself and on the additional projection or side wall. Slots or recesses (preferably
vertical, or approximately so) are provided in the roller standard and in the
additional projection or wall thereon to allow of the wire pulley being easily
placed in position, said slots or recesses providing for the passage of the pulley
trunnions.
Although I have described the additional projection or side wall on the roller
standard as projecting upward from the foot or base of said standard yet it is
obvious that a downward projection from the side of the standard and open at
its lower end might be provided if desired. I might also provide a wire pulley
or wheel with fixed spindle or screw in lieu of the travelling or anti-friction
pulley above described in which case the elongated slots or paths would be re-
placed by suitable holes or bearings.
As a modification the wire may be run either over or under the top travelling
or anti-friction roller in which case a groove of suitable size or formation would
be provided in said roller for the wire to run in and the top lugs of the roller
standards or supports as described in said Specification of Letters Patent
No. 24466 of A.D. 1893 would be extended in a lateral direction and also widened
so that the lugs on each pair of standards would meet thus forming a hood or
guard for the wire; or, in lieu of the wire bearing on the top point rod roller a
separate pulley wheel may be mounted to rotate on the bolt which passes through
the said top lugs on the standard which lugs would in this case also be enlarged

page_text: and provided with lateral projections or flanges so as to form a hood or guard for
the pulley.
As a further modification, in the case of channel rodding in which the bottom
roller works in the channel and is consequently much narrower than the rollers
employed for round rodding a double number of wire pulleys may be provided
on each roller standard, that is to say one on each side of the standard.

An Improved Combined Support for the Operating Rods and Wires of
Railway Points and Signalling Apparatus.
I, ARTHUR GEORGE EVANS, of "Kington Langley," Chippenham, formerly of
"The Clift," Chippenham, in the County of Wilts, Civil Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to a combined travelling point rod roller or support
and wire pulley or support for use in connection with railway signalling
apparatus, and consists in improvements in connection with the invention set
forth in the Specification of Letters l'atent granted to me No. 24466, dated
December 20th 1893; it is also applicable in connection with the inventions set
forth in the Specifications of Letters Patent granted to me Nos. 13004 A.D. 1891
14304 A.D. 1897, and 16369 A.D). 1897.
In the above cited prior inventions side standards or supports are described
as having elongated top and bottom slots or paths for the trunnions of the tra-
velling rollers on which the point rod bears to revolve and travel along, and top
lugs and bolts with distance picces or ferrules, and my present invention consists
in forming or fixing on said standards supports for wires used in railway
signalling.
In order that my invention may be better understood and more readily carried
into effect I will describe it with reference to the accompanying drawings which
illustrate various ways in which I carry out my invention.
Figures 1 and 2 illustrate the way in which I prefer to carry out my inven-
tion, Figure 1 being an end view partly in section showing three wire pulleys
(top and bottom pulleys) supporting three wires over one pair of roller standards.
Figure 2 is a side view of Figure 1.
Figures 3 to 12 inclusive show modifications.
The same letters refer to the same parts in the various figures of the drawings.
Referring to Figures 1 and 2, a a are the standards supporting the point rod
rollers, as described in my Specification No. 24466/93 herein before referred to,
7,6 being respectively the top and bottom travelling rollers and c c¹ the top
lugs on the standards (referred to in my said Specification No. 24466/93) d d d d³,
are castings one on each side of the top lugs c c respectively, said castings
having elongated recesses or slots g about their middle for the trunnions of
the pulleys to revolve on and travel along. The castings d d¹³ ³ are provided
with lateral projections e e e e³, respectively, which take the place of the dis-
tance pieces or ferrules as described in my Specification No. 24466/93. are
small top pulleys which are supported and revolve on the bolt or rod & passing
through the top of the castings d d¹ de d³; 1 are lateral projections at the top

page_text: of the castings d, which form guides for the wires m. It will be seen by this
arrangement that a series of wire pulleys or supports can be readily built up
on the roller standards a, all parts being interchangeable.
It is obvious that in lieu of providing two castings to form a support for each
wire pulley a single casting might be provided in which case grooves or passages
would be formed in the casting for the passage of the trunnions h so that the
pulleys could be dropped into position from the top.
In Figures 3 and 4 the projections ce on the casting d are formed to take
the place of the distance pieces or ferrules described and illustrated in my prior
Specification No. 14304 of 1897.
In Figure 5 no provision is made for a top wire pulley and the ferrule or dis-
tance piece is the same as that set forth in Specification No. 24466 of 1893.
In Figures 3, 4, 5 and 9 the arrangement shown only provide for supporting
one wire on each pair of roller standards. In Figure 9 the top point rod roller
is provided with a groove and itself acts as the wire pulley, the distance piece or
ferrule being provided with a projection n which acts as a guide for the wire.
In Figures 6 & 7 (Fig. 7 being a side view of Figure 6) the wire pulley support
is formed in one with the roller standard, lateral projections / being also provided
in this case as guides for the wire.
In Figure S are ribs on the wire pulley castings or supports d¹ respec-
tively, which fit in corresponding grooves or passages in the lug c of the roller
standard.
Figures 10, 11 and 12 illustrate my invention where the wire pulleys are pro-
vided at the base of the roller standards. o is a bracket or wall piece connected
to the feet of the roller standards the part of extending over and joining the
standard so as to form a hood or guard for the wire. The trunnions h of the
wire pulley bear and travel on recessed or slotted paths p 21 (Fig. 10) in the
wall piece or bracket o and in the roller standard itself, respectively, a vertical
slot (Fig. 11) being also provided in the roller standard so as to provide for
readily placing the pulley in position.
In Figures 5, 6, 7, 8, 10, 11 and 12 the distance piece or ferrule between
the top lugs on the roller standards is the same as that shown in Specification
No. 24466 of 1893.
My invention is applicable to angle pulleys.
Although I have herein described point rod roller standards or supports pro-
vided with elongated slots or paths for the trunnions of the rollers to revolve
on and travel along, yet I do not debar myself from employing roller standards
or supports and rollers of ordinary construction.
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 railway signalling the means described of supporting travelling wire
pulleys by and above the side cheeks or supports of point rod rollers, substan-
tially as illustrated in the drawings annexed.
2. In railway signalling a side cheek or roller standard for point rods receiving
a travelling roller and a travelling wire pulley below said roller, substantially
as herein set forth with reference to the drawings annexed.
