PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Straightening
Railway or other Metal Rails or Bars.
I LEWIS RICHARDS of 13 Charlotte Street, Dowlais, in the County of Glamorgan,
Engineer do hereby declare the nature of this invention to be as follows:-
These improvements relate to apparatus for use in effecting the straightening of
railway and other metal rails or bars.
The improved apparatus is arranged so as to be readily adaptable to operate on
various sections of rails or bars or sizes and forms of the same.
In carrying out my invention rollers are arranged in groups so as to cooperate
together to straighten a rail or bar submitted to them, and are capable of rotating at
a distance apart adjustable to the size or conformation in section of the rail or of the
rail head or part.
For instance supposing a rail of flat bottom shape the head may be engaged between
two rotating rollers having the same direction of motion and both borne upon axis
having a coincident axial line but the axis of each being a separate roller the one roller
having a projecting part entering a recessed part in the other, the extent of the
recession being adjustable so that the sides of the rollers and the cylindrical portion of
the roller may form a variable receptacle for the rail or bar head, whilst the flat or
other part of the rail is carried by other rollers preferably arranged with their axes
parallel and in the same plane as the head rollers and rotating at right angles to the
line of rotation of the head rollers.
These lower rollers rotate in opposite direction one to the other and the rail rests on
their sido surfaces so as to drive or draw the rail onward in cooperation with the head
rollers.
The direction of motion is variable and the relative distances apart is adjustable to
the height of rail and other circumstances also the angle of the rollers to the vertical
may be varied.
The number of groups of rolls may be adapted to requirements.
The groups are driven by suitable gearing and the rollers are supported in suitable
and usual bearing parts and as well as means for reversing the direction of motion so
that the rail or bar may be made to travel either way and varying speed, proper
adjustable guides (such as blocks or rollers) are provided for actuating and conducting
the rails or bars correctly into and out from the machine as required.

I LEWIS RICHARDS of 13 Charlotte Street, Dowlais, in the County of Glamorgan,
Engineer do hereby declare the nature of this invention and in what mauner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
These improvements relate to apparatus for use in effecting the straightening of
railway and other metal rails or bars.

distance apart adjustable to the size or conformation in section of the rail or of the rail
head or part.
For instance supposing a rail of flat bottom shape the head may be engaged between
two rotating rollers having the same direction of motion and both borne upon axes
having preferably a coincident axial line, but the axis of each being a separate roller
the one roller having a projecting part entering a recessed part in the other, the extent
of the recession being adjustable so that the sides or annular surfaces of the rollers and
the cylindrical portion of the roller may form a variable receptacle for the rail or bar
head, whilst the flat or other part of the rail is carried by other rollers preferably
arranged with their axes parallel and in the same plane as the axes of the head rollers,
and rotating at right angles to the line of rotation of the head rollers.
These lower rollers rotate towards each other or in opposite direction one to the
other, and the rail rests on their side surfaces so as to drive or draw the rail onward
in co-operation with the head rollers.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a front view.
Fig. 2 an end view, and
Fig. 3 a plan view of an arrangement of rollers adapted to co-operate together to
straighten a rail, herein shewn as a flat bottom rail.
a, a¹ are two rollers rotating in the same direction, indicated by the arrows thereon,
and both borne upon axes a³, a³ respectively having a coincident uxial line and carried
in suitable bearings of the ordinary description and therefore not shewn. The project-
ing part at of the axis of the roller a¹ passes within the roller a, the extent of this
recession of the part a within the roller a being adjustable, so that the sides of the
rollers and the cylindrical portion at may form a variablo receptacle for the head b¹ of
the rail b, whilst the flange or flat part of the rail is supported by two other
rolls c, d, arranged with their axes parallel and in the same plane as the head
rollers a, a, and rotating at right angles to the line of rotation of these head
rollers α, a. These rolls c, d rotate in opposite directions one to the other, and the
flange 6 of the rail b rests on their upper side surfaces, so that these surfaces draw the
rail onward, co-operating with the rollers a, a, and with the part rollers c, d, which
are adapted to receive between then the web of the rail, the bevelled insides c*, d², of
each of the rolls c¹, d¹ pressing on the upper bevelled sides of the flange.
The direction of motion is variable, and the relative distance apart is adjustable to
the height of rail and other circumstances, also the angle of the rollers to the vertical
may be varied.
The number of groups of rolls may be adapted to requirements.
The groups are driven by suitable gearing of ordinary and well understood
description and therefore not shewn, and the rollers are supported in suitable and
usual bearing parts, and as well as means for reversing the direction of motion so that
the rail or bar may be made to travel either way, and varying speed; proper adjust-
able guides (such as blocks or rollers) are provided for actuating and conducting the
rails or bars correctly into and out from the machine as required.
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 :-
In machinery or apparatus for straightening railway or other metal rails or bars, the
combination or arrangement and use of rollers a, a¹ to co-operate with rollers c, d,
or c, c, d, d', to straighten rails as and for the purpose and in manner substantially as
set forth.
