We, JOHN SAXBY, JOHN STINSON FARMER and CHARLES HODGSON of Canterbury
Road Kilburn in the County of Middlesex, Engineers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the supporting guides for the rods that are used to com-
municate movement to objects on railways such as the points, the signals, the gates
and the bolts or locks of these. Many of these rods extend over considerable distances
and require considerable force in working them. The object of our invention is in a
cheap and simple manner to provide for their easy movement to and fro. For this
purpose we fix at suitable intervals brackets or frames consisting of two upright cheeks
with a space between them. On the inside of each cheek we form a shelf orlevel
surface terminating at each end of it with an uprightly projecting shoulder.
In the space between the two cheeks we place a pulley having its axis projecting
a little on each side so that each projecting part is on one of the shelves above
mentioned. On the upper surface of the pulley is laid the rod which has to be
supported. When it is pulled to or fro, the pulley is caused partly to revolve and
its axis roll along the shelves on which they rest, the extent which they travel along
it being much less than the travel of the supported rod. At a little distance above
the rod we prefer to mount on the cheeks a roller which prevents the rod from being
accidentally lifted from off the pulley.

We JOHN SAXBY, JOHN STINSON FARMER and CHARLES HODGSON, of Canterbury
Road Kilburn in the County of Middlesex, Engineers 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 :-
This invention relates to the supporting guides for the rods that are used to com-
municate to and fro movements to objects on railways such as the points, signals,
gates, their bolts or locks, and the like. Many of these rods extend over considerable
distances and require considerable force for working them. The object of this invention
is to provide in a cheap and simple manner for their easy movements to and fro. For
this purpose, we fix at suitable intervals supports of the kind represented in the
accompanying drawings. Fig. 1. is a side view partly in section, and Fig. 2 an end
view of a support suited for a round rod. Figs. and 4 are corresponding views
of a support suited for a rod of inverted trough shape. A is a frame consisting of
a base and two side cheeks, each of which has projecting inwardly a recessed shelf a.
B is a pulley or roller made with a central pivot b projecting at each side of it. C is
the rod that is supported on the periphery of the roller B, and is prevented from
rising by a small roller D mounted in the frame above it. As the rod C is moved to,
and fro the pulley B is caused to turn partly round and its central pivot b to travel
along the recesses of the shelves a the distance which they travel being less than the
distance moved over by the rod C in proportion as the diameter of the pivot b
is less than that of the pulley B. The frame A with its recessed shelves a being
cast in one piece, and the pulley B with its pivots being also cast in one
piece, the construction is very inexpensive, and as the pivots & roll along the shelves,
instead of turning in bearings, the frictional resistance is reduced to a minimum. The
rod C is shewn in the drawings as a round tube or as a trough shaped bar which are
forms largely adopted. It is obvious, however, that, when rods of other forms are
employed, it is only necessary to make the circumference of the pulley B and of the
roller D of suitable section.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim is :-
The construction and use of a supporting guide for rods communicating to and fro
movements on railways, consisting of a pulley or roller having pivots of relatively
small diameter arranged to roll along recessed shelves on the side cheeks of a frame
between which the pulley or roller is mounted, substantially as herein described.
