PROVISIONAL DE MOTIVATION
Improvements in Covering Iron Drawing Rollers of Drawing Frames
for Flax, Hemp, Jute and similar Fibres.
We JAMES BARBOUR Machinist-and-SAMUEL MOODY Worker in Leather both of Falls
Foundry Belfast Ireland, do hereby declare the nature of-this-invention to be as
follows:-
The method up till now in use of attaching the necessary plies of leather to
drawing rollers is as follows.
Two plies of leather are used, the first ply being attached to the iron roller
by means of cement and wooden pegs which are passed through the leather as
ordinary nails and enter corresponding holes drilled in the surface of drawing
roller. This ply when properly dried is turned in a lathe so as to remove all
inequalities and reduce the ply of leather to one uniform thickness-the second ply is
then stuck to the first ply by means of cement, the abutting ends being further
secured by small wooden pegs.
Where great pressures are required this method is not found sufficient to keep the
plies of leather in position.
To remedy this defect we propose to secure the outer ply in addition to the
present method by using drawing rollers provided on either side with loose flanges,
and by making the top ply of leather broad enough to overlap the sides of the
drawing roller, and be turned down in a radial direction, so that the loose
flanges on being tightened up will catch and clip the leather into the sides of
the roller and thus secure the leather.

Improvements in Covering Iron Drawing Rollers of Drawing Frames
for Flax, Hemp, Jute and similar Fibres.
We, JAMES BARBOUR, MACHINIST, and SAMUEL MOODY, Worker in Leather, both of
Falls Foundry, Belfast, Ireland, 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 improvements in the manufacture of the drawing
rollers of frames for drawing flax, hemp, and similar fibres, and consists in
covering the rollers with plies of leather attached to such rollers by means of

page_text: loose flanges or washers and bolts whereby the leather covering is securely fixed
to and held in position on the roller, and a more durable and effective working
roller is obtained. Heretofore drawing rollers have been covered with leather in
the following manner :-Two plies of leather were used, the first ply being
attached to the iron roller by means of cement and wooden pegs passed through the
leather as ordinary nails entering corresponding holes drilled in the surface of the
drawing roller; this ply when fixed in position and properly dried was turned in
a lathe so as to remove all inequalities and reduce the ply of leather to one.
uniform thickness. A second ply of leather was then stuck to the first ply by
Ineans of cement, the abutting ends of the ply being further secured by small
wooden pegs. This method was not found sufficient to maintain the plies of
leather in position when subjected to a great pressure as is often the case, and
the object of the present invention is to remedy this defect.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Fig. is a side elevation of a drawing roller covered in the manner hereinafter
described.
Fig. 2 is an elevation, partly in section of Fig. 1.
According to this invention, at 1 is a wooden rim fixed in the flanged iron
pressing roller 2, and to this wooden rim 1 an inner ply of leather 3 is cemented
and pegged. The outer ply of leather 4 is broad enough to cover the face of
roller 2, and also to overlap at each side, the overlapping portions of the leather
being notched or cut radially as at 5, in order to allow of the leather 4 lying
evenly on the surface of the roller and being fastened by means of loose flanges
or rings, or by means of a number of washers 6-6, such flanges, rings, or
washers 6-6 being tightened and securely held by bolts 7.
The flanges, rings, or washers 6-6 being made to fit the ogee part 8 of the iron
roller 2, hinge or fulcrum on this part (see Fig 2) and the effect of screwing up
the bolts 7-7 tightens and stretches the outer ply 4 and holds it securely in
position.
By the means herein described the plies of leather 3-4 are securely held in
position, and will stand much higher pressure than hitherto, and a more effective
working roller is obtained.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is
A drawing roller the periphery of which is covered with leather notched or cut on
the edges which overlap the sides of the roller and secured thereto by rings or
washers and bolts, as and for the purpose herein described and substantially as
illustrated by the drawings annexed hereto.
