PROVISIONAL SPECIFICATION.
Improvement in Roller Frames for Point or Signal Rods.
I SAMUEL TELFORD DUTTON of Mari Bank in the City and County of
Worcester, Civil Engineer do hereby declare the nature of this invention to be as
follows:-
My present invention relates to improvements in the frames or supports of the
rollers (whether traversing or rotating on a fixed axis) used for carrying point
rodding, the various parts of which are built up and bolted together in sets or
series to suit the number of the rods.
Hitherto the bolts or pins for connecting the frames together or for carrying the
rollers have been made in one piece and of different lengths according to the
number of the frames.
The disadvantage of this arrangement is that in case of alterations or additions
to the number of rods to be carried the bolts or pins already provided are useless
and have to be replaced by others of a different length.
My invention avoids this inconvenience, the frames being formed in such a
manner that two adjoining ones can be bolted together with bolts of one standard
length placed alternately on opposite sides of the frame clear of one another.
In some cases these bolts carry the rollers.
Distance pieces are placed between or cast on the frames; these may serve as
covers to protect the rollers and roller paths or as studs to carry the top rollers or
as guards over the rods instead of top rollers.
The frames being firmly bolted together require fewer holding down screws than
those connected in the ordinary way by a loosely fitting pin.
A similar method of bolting together may be applied to roller frames of wrought
iron made in a suitable form.
Dated this 6th day of February 1896.

COMPLETE SPECIFICATION.
Improvement in Roller Frames for Point or Signal Rods.
I SAMUEL TELFORD DUTTON, of Marl Bank in the City of Worcester, Civil
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 :-
In the case of frames or supports of point rollers (whether traversing or rotating
on a fixed axis) the various parts of which are built up and bolted in sets or series
the bolts or pins for connecting the frames together or for carrying the rollers
have hitherto been made in one piece and of different lengths according to the
number of the frames.
Every variation in the number of rollers in a set entails an alteration in these
fastenings and when an addition or alteration has to be made to the number of
existing rods the bolts or pins become useless and have to be replaced by others of
a different length.

page_text: My invention avoids this inconvenience by forming the frames in such a manner
that bolts or pins of one length can be be used to fasten them together so that
frames and rollers when put together for any number of rods will consist of entire
sets of similar and interchangeable parts.
In order that my invention may be better understood and more readily carried
into effect I will proceed to describe it with reference to the accompanying drawings
in which similar letters refer to similar parts in the several figures.
Figs. 1. 2 and 3 are different views and sections of frames with traversing rollers.
The feet of these frames are dowelled or dovetailed together and fastened down in
the usual manner. The top of the frames have flanges A which meeting over the
rod protect the rollers and form distance pieces for bolting together. B. Bare
the bolts for holding the frames together on alternate sides. These bolts are made
to suit different widths of frame but in each case they are of a standard length and
size for any number of rollers. They may have either square or hexagon heads or
may be made with a square under a half round head as shown in Fig. 3. Instead
of a bottom roller running in a slot as shown in Fig. 1 it may revolve on a pin C
shown in Fig. 4 in which case each piu has a separate bearing and is made in short
lengths to suit the number of rollers instead of being in one length and passing
through a set of rollers.
Figs. 5 and 6 show a modified arrangement of roller frame in which the
bolts D D for fastening the frames together carry the bottom rollers E. E. which
are placed alternately on opposite sides of the frame. The top roller F is carried
on studs G. G. cast on the frame. These studs act also as distance pieces.
Figs. 7. 8 and 9 show another modification in which the bolts H. H. pass
through lugs on the top of the frame their length being thereby reduced to a
minimum.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed 1 declare that what I
claim is-
Roller frames for point or signal rods formed in such a nanner that they can be
put together for any number of rods with bolts or pins of uniform size and length
substantially as hereinbefore described and shown in Figs. 1 to 9.
Dated this 13th day of June 1896.
