PROVISIONAL SPECIFICATION.
Improvements in or applicable to the Operating Rods of Signals and
Switches and other Railway Appliances.
HENRY KEELING, Engineer, 42, Prospecthill Road, Langside, Glasgow, do here-
by declare the nature of this invention to be as follows:-
My invention has reference to the protection of the operating rods of signals
and switches and other railway appliances, against wear at their bearings, and
the prolongation of the life of the rod is the object I bave had in view in perfect-
ing this invention. For this purpose I apply a detachable metalic covering
to the rod at the bearings, which covering takes up the wear due to the move-
ment of the rod. The covering is secured to the rod by means of bolts, rivets,
keys or their equivalents.

Improvements in or applicable to the Operating Rods of Signals and
Switches and other Railway Appliances.
I, HENRY KEELING, of 24, Prospecthill Road, Langside, in the City of Glasgow,
Engineer, 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:-
My invention has reference to the protection of the operating rods of signals
and switches and other railway appliances against wear at their bearings, and
the prolongation of the like is the objecct I have had in view in perfecting this
invention.
For this purpose I apply a detachable metallic covering to the rod at the bear-
ngs, which covering takes up the wear due to the movement of the rod.
The covering is secured to the rod by means of bolts, rivets, keys or their
equivalents.
"The invention is illustrated by the accompanying drawings, Figure 1 being
a longitudinal elevation and Fig. 2 a transverse vertical section showing the
method of forming and attaching the metal covering to rods of round section.
Figures 3 and 4 are like views respectively of the device as applied to rods of
channel section, and Figure 5 shows its application to a rod of T section.
In applying the covering to rods of round section, I construct the protective
slipper A of curved form, adapted to bear upon the guide roller or pulley B

page_text: carried by the usual bracket C and having upwardly projecting lugs A¹ whereby
the slipper may be clamped by bolts D to the signal or switch rod E. The wear
which would otherwise detract from the strength of the rod is thus wholly taken
up by the protecting slipper so that the original strength of the rod E is main-
tained, and all risk of accident from breaking is avoided.
In the example shown at Figures 3 and 4, the slipper A is secured to an
operating rod of channel section by bolts G, the guide roller H bearing upon
the slipper A between the flanges of the channel iron.
In the example shown at Figure 5, the slipper A is secured to the vertical
web of a Tiron I, in the same manner as at Figures 3 and 4, the guide rollers
bearing upon said slipper A on either side of the vertical web.
The protective slipper is equally suitable when ball bearings are employed for
supporting the rod, instead of roller bearings as shown.
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―
The combination with a point or switch rod of a protective slipper or covering
secured thereto, and serving as a wearing surface where such rod is supported
on pulleys or other guides.
