PROVISIONAL SPECIFICATION
Improvements in connection with the Supports or Bearings for the
Operating Rods of Signals and Switches and other Railway
Appliances.
I, ARTHUR GEORGE EVANS, of 116, Palace Chambers, Westminster, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion to be as follows:
to me.
-
My invention has reference to improvements on the invention described in the
Specification of Letters Patent No. 24466, dated December 20th 1893, granted
In that specification the invention set forth consisted in the addition of
a lug to the top of each standard, providing a ferrule between each pair of
standards and threading a bolt through said lugs and ferrules for the purpose of
holding the standards firmly together at the top, so preventing any working out
of the top rollers. With this invention and with the invention set forth in the
prior Specification of Letters Patent granted to me, No. 13004 of A.D. 1891, if it
was required to remove the top roller in order that the rod beneath might be taken
out it was necessary to move aside the standards on each side of the rod required
to be removed in order to get the necessary space for the spindles or trunnions
of the top roller to clear the standards so as to get said roller out; in thrusting
aside the standards to get this space other standards would also be moved aside
and frequently during this movement the top rollers got out of their position and
the set of standards and rollers required fresh building up, thus causing trouble
and inconvenience.
With my present invention in order to obviate the disadvantages above men-
tioned and to enable the standards to always keep in their upright position even
when rods are required to be removed, I arrange that the upper slot or path in
each standard receiving the top roller is open at one end so that the top rod may
be conveniently taken out. In order to fill up the open ends of the top slots in
the standards and prevent the rollers from being thrust out I provide a bolt
which is inserted midway through the upper and lower paths of the top slot. It
will thus be seen that by loosening the nut and withdrawing the bolt the top
rollers may be taken out without disturbing the remaining parts of the set of
standards. For a set of say, (for example) a dozen rollers side by side, in lieu
of providing a separate bolt for closing the open end of the top paths or slot in
each standard, bolts would only be provided in the standards at each end of the
set each of said bolts passing through a hole in a suitable cross bar extending
across the open ends of the top slots of all the standards in the set thereby closing
the paths ou which the top rollers revolve.
My invention as above described may be applied to the bottom slot or path of
each standard so that the bottom roller may be readily removed if desired.

I, ARTHUR GEORGE EVANS, of 116, Palace Chambers, "Westminster, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
to me.
My invention has reference to improvements on the invention described in the
Specification of Letters Patent No. 24466, dated December 20th 1893, granted
In that specification the invention set forth consisted in the addition
of a lug to the top of each standard, providing a ferrule between each pair of
standards and threading a bolt through said lugs and ferrules for the purpose of
holding the standards firmly together at the top, so preventing any working out
of the top rollers. With this invention and with the invention set forth in the
prior Specification of Letters Patent granted to me, No. 13004 of A.D). 1891, if it
was required to remove the top roller in order that the rod beneath might be taken
out it was necessary to move aside the standards on each side of the rod required
to be removed in order to get the necessary space for the spindles or trunnions
of the top rollers to clear the standards so as to get said roller out; in thrusting
aside the standards to get this space other standards would also be moved aside
and frequently during this movement the top rollers got out of their position and
the set of standards and rollers required fresh building up, thus causing trouble
and inconvenience.
It
With my present invention in order to obviate the disadvantages above men-
tioned and to enable the standards to always keep in their upright position even
when rods are required to be removed, I arrange that the upper slot or path in
each standard receiving the top roller is open at one end so that the top rod may
be conveniently taken out. In order to fill up the open ends of the top slots in
the standards and prevent the rollers from being thrust out I provide a bolt
which is inserted midway through the upper and lower paths of the top slot.
will thus be seen that by loosening the nut and withdrawing the bolt the top
rollers may be taken out without disturbing the remaining parts of the set of
standards. For a set of say, (for example) a dozen rollers side, by side, in lieu
of providing a separate bolt for closing the open end of the top paths or slot in
each standard, bolts would only be provided in the standards at each end of the
set each of said bolts passing through a hole in a suitable cross bar extending
across the open ends of the top slots of all the standards in the set thereby closing
the paths on which the top rollers revolve.
In order that my invention may be better understood and more readily carried
into effect I will now describe it with reference to the accompanying drawing in
which,--
Figure 1 is a side elevation of one of my improved roller standards, Figure 2
being a plan of a pair of said standards, and Figure 3 a plan showing the appli-
cation of my improvements where two or more rods run side by side consequently
requiring three or more standards, three standards being shown.
The same letters refer to the same parts in the different figures.
a are the roller standards, and c being respectively the paths on which the
trunnions or spindles of the top and bottom travelling rollers revolve; d are the
bolts closing or blocking the openings e at one end of the tops slots or paths b
said bolts d passing through the upper and lower sides of said top slots. Referring

page_text: to Figure 3, where three or more standards are arranged side by side it is only
necessary, as before mentioned, to provide bolts d to each end standard of the set,
the bolts d in this case passing through the ends of a suitably shaped bar or rod j
which extends across the whole set of standards closing the open ends e of all
the top slots or paths b.
f (Fig. 2) are the top lugs of the standards, h the distances pieces or ferrules
and g the bolts passing through said lugs and ferrules and preventing lateral move-
ment or separation of the standards a.
In order to remove a top roller it is only necessary to remove the nut of bolt d
on each standard and withdraw said bolt, when the top roller can be removed
without disturbing the remaining parts of the set of standards. In the case of a
set of three or more standards as illustrated in Figure 3 it is only necessary to
remove the bolt d at one end of the set the rod or bar j being then swung round
on the other bolt which acts as a pivot when any desired roller in the set can be
removed.
My invention as above described may be applied to the bottom slot or path of
each standard so that the bottom roller may be readily removed if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In antifriction supporting guides for rods employed in railway signalling
apparatus, consisting of side standards having top and bottom paths for the
trunnions of the rollers to revolve upon, top lugs, a spacing ferrule between the
standards, and a bolt passing through said top lugs and ferrule, providing
openings e at the ends of the slots forming the paths on which the trunnions of
the top rollers revolve, and bolts d passing through the top and bottom sides of
said top slots or paths to close said openings e, substantially as and for the purpose
described with reference to Figures 1 and 2 of the accompanying drawing.
2. In antifriction supporting guides for rods employed in railway signalling
apparatus, standards a having openings e at one end of the slots or paths on which
the trunnions of the top (or bottom) roller revolves said openings being closed
by means of bolts d or bolts d and rod or bar j (Figure 3) substantially as and
for the purpose set forth.
