I, HAYES BRUXBY, of 29, Otter Street, Derby, in the County of Derby, Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a simple form of lever compensator
with as few and inexpensive parts as possible.
In carrying out my said invention I employ a cross bar pivotted in the line of
the rods between two plates or side frames carried upon any suitable bed or base
fixed in the usual manner to a sleeper or the like; distance pieces being cast,
formed upon or otherwise fixed to one or both the side frames, one of the latter
being preferably formed solid with the bed and the other being removable for
repairs. The outer ends of the cross bar have slotted openings therein and are
pivotted through these openings between lugs carried on slides which work in
guides or ways and upon rollers carried between the two plates or side frames.
These slides are curved inwards and jointed to the rods in a manner capable of
The slots in the crossbar are made
allowing for any lateral play of the said rods.
sufficiently long to allow for contraction and expansion of the rods and for the
slides to move freely backwards and forwards upon the rollers and in the guides
or ways between the two side frames or plates.
The latter are bolted together preferably by utilizing the roller pins for the
purpose and the whole may be provided with any suitable cover or cap capable
of being readily removed for lubricating or other purposes.
The only parts likely to become much worn are the centre pin and the joints
between the cross bar and slides, all of which may be readily and inexpensively
replaced.
Instead of pivotting the ends of the cross bar between the lugs on the slides
I may if desired simply place the ends of the said bar in slots formed between the
lugs and in the slides, although I prefer the pivotted connection between the cross
bar and slides as already described.

I, HAYES BRUXBY, of 29, Otter Street, in the County Borough of Derby, 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:-
The object of my invention is to provide a simple form of lever compensator
with as few and inexpensive parts as possible.
In describing my invention reference will be had to the accompanying sheet
of drawings upon which Figure 1 is a side elevation of my improved apparatus
or device, the front plate being removed, as will be hereinafter explained.
Figure 2 is an end elevation of the same.
In carrying out my said invention I employ a cross bar A pivotted in the line
of the rods between two plates or side frames B, C carried upon any suitable bed
or base C¹ fixed in the usual manner to a sleeper or the like; distance pieces D
being cast, formed upon or otherwise fixed to one or both of the side frames, one
of the latter C being preferably formed solid with the bed C₁ and the other B
being removable for repairs. The outer ends of the cross bar have slotted
openings A therein and are connected through these openings between lugs E¹, Fi
carried on slides E, F which work in guides or ways and upon rollers G carried
between the two plates or side frames. These slides are curved inwards and
jointed at E and F to the rods in a manner capable of allowing for any lateral
play of the said rods. The slots in the cross bar are made sufficiently long to
allow for contraction and expansion of the rods and for the slides to move freely
backwards and forwards upon the rollers and in the guides or ways between the
two side frames or plates.
The latter are bolted together in any suitable manner and the whole may be
provided with any suitable cover or cap H capable of being readily removed for
lubricating or other purposes.
The only parts likely to become much worn are the centre pin and the joints
between the cross bar and slides, all of which may be readily and inexpensively
replaced.
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
In a compensator for rods operating points, detectors, lock bars and the like:
a cross bar A pivotted centrally between two side plates or frames B, C, the said
cross bar having slotted openings therein and being connected through same with
slides E and F the latter being free to move backwards and forwards in guides
or ways and upon rollers G, the said slides being connected at their outer extremi
ties to the point rods or the like, substantially as and for the purposes described
and illustrated.
