PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Saddles for Wet Spinning
Frames.
ROBERT HENRY STURROCK READE, Managing Director of York Street Flax
Spinning Company Limited, Belfast, and HUGH MCKIBBIN, Foreman, Mechanic
in the employment of the said Company do hereby declare the nature of this
invention to be as follows:
This improvement in the construction of saddles for the pressing rollers of wet
spinning frames relates to that sort of saddle used in wet spinning frames in which
the guiding or controlling arm of the saddle is above or outside the pressing rollers.
The usual method of constructing this class of saddles is to cast the arms and
shank or slide for top bush in one piece. Formerly the stands which have grooves
to carry or guide the arms of the saddles were formed with webs to prevent the
end wise movement of the pressing rollers, the pivots or ends of the pressing rollers
being in contact with the webs of the stands.
The exigencies of working led to the removal of these webs, and the saddle
itself was made to control not merely the position of the pressing rollers round
the bottom rollers but also to control the position of the pressing rollers endwise.
In practice it has been found that the slight irregularities in the grooves in the
stands which carry the arms of the saddles together with the constant tendency
that the pressing rollers have to move end wise cause the end wise position of the
bosses of the pressing rollers over the bosses on the retaining and drawing rollers
to become irregular or out of line, and the difficulty has been to correct these
irregularities of position, there being no means of adjusting the ends of the arms
of the saddle by reason of the arms and shank of the saddle being in one piece.
This inprovement in the construction of saddles for wet spinning frame rollers
is designed to correct or adjust, and provides a simple and effectual means for
correcting or adjusting, the position of the pressing rollers endwise, and consists in
making the shank of the saddle and the arms in separate pieces and joining them
together by a screw, a flat surface being formed on one side of the arms which is
screwed against a suitable face on the shank of the saddle.
Thus a simple and practical means is provided for the exact adjustment of the
position endwise of the pressing rollers, and a practical difficulty in the working of
the outer-armed saddle is overcome.

An Improvement in the Construction of Saddles for Wet Spinning
Frames.
We, ROBERT HENRY STURROCK READE, Managing Director of York Street
Flax Spinning Company Limited, Belfast, and HUGH M'KIBBIN, Foreman
Mechanic, in the employment of the said Company, 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 that type of saddle for the pressing rollers of wet
Pri Q77

page_text: spinning frames in which the guiding or controlling arm of the saddle is above or
outside the pressing rollers.
Formerly the roller stands which are provided with U grooves to support or
guide the arms of the saddles were formed with webs which extended between the
ends of the axle of the pressing rollers to prevent endwise movement thereof the
axle ends being in contact with such webs. And the saddles have hitherto been
formed with the arms, and the shank or slide for the top bush, cast in one piece.
In the present construction of roller stand, the webs have been removed and the
saddle alone controls not merely the position of the pressing rollers round the
bottom rollers but also any end wise movement of the rollers, and no provision has
been made for adjusting the saddles.
We have found that owing to slight irregularities in the U grooves in the stands
which support or guide the saddle arms and to the pressure exerted laterally on the
saddles by the end thrust of the roller axles, the saddles become twisted or moved
out of their proper vertical position and consequently do not keep the bosses of
the pressing rollers in line with the bosses of the drawing rollers as it is desirable
they should be.
It is to provide for such an adjustment of the saddles as that they can be moved
either to right or left to compensate for any unevenness in their supports or undue
thrust of the rollers that this invention is designed and it consists essentially in
constructing the saddle with the arms separate from the shank and attached thereto
by a bolt, screw or the like so that the relative position of the two can be altered
or adjusted as required to maintain the bosses of the rollers iu line.
The invention will be fully described with reference to the accompanying
drawings.
Fig. 1. Front elevation.
Fig. 2. Longitudinal section.
Fig. 3. Perspective view showing the parts separated.
The shank A of the saddle is cast in a piece separate from the arms B and the
two parts are fitted together and held in position by the screw C.
A flat surface b is formed on one side between the arms which abut against a
corresponding flat surface a on the shank A. A hole a' in the shank A is tapped
to receive the screw C which passes through the hole in the arms B.
The hole is preferably in the form of a slot to allow of a short longitudinal
movement. Instead of employing a set screw C, a slot may also be made in the
shank and a bolt substituted therefor.
The position of the shank of the saddle can be easily adjusted or set to any
desired position by moving it about the screw C as a pivot or moving the screw
along the slot b¹.
By this construction a practical means is provided to correct any irregularities
in the position of the saddle and for the adjustment of the pressing rollers to bring
their bosses into line with the bosses of the retaining and drawing rollers, and a
practical difficulty in the working of the outer armed saddle with the present form
of stands is overcome.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
A saddle for the rollers of wet spinning frames, constructed with the shank and
the arm made in separate pieces and connected or attached together by set screw
or bolt substantially as and for the purposes described.
