page_text: An Improvement in Flyers for Spinning Machines.
I, CHARLES MAURIS, of 27 Great George Street in the City of Westminster,
Civil Engineer, do hereby declare the nature of my said invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accompanying sheet
of Drawings and to the letters and figures marked thereon :-
My improvement relates more especially to the flyers of throstle frames, but is
also applicable to the flyers of other similar machines. Its object is to prevent the
thread from rubbing against any part of the arm of the flyer in its passage from
the drawing rollers to the eye on the end of the flyer arm, and it consists in
making the flyer so, that its two arms, instead of projecting from opposite sides of
the boss by which it is screwed on to the spinning spindle in radial lines coinciding
with a plane passing through the centre of the said boss as has been the practice
heretofore, shall project therefrom tangentially, or otherwise, in such manner that
the upper parts of the arms of the flyer, which stand more or less at right angles to
the spinning spindle, shall be removed out of the line of direction of the thread
between the drawing rollers and the eye of the flyer, so that the thread does not
rub against, or even touch it.
In the Drawings hereto annexed, Figure 1 is a front view, Figure 2 a side.
view, and Figure 3 a plan, of a throstle flyer constructed in accordance with my
invention.
A is the boss of the flyer which screws on to the spinning spindle in the usual
way. BB represent in dotted lines (see Figure 3) the arms of the flyer as they
would be made and placed according to the ordinary method of construction, that
is to say, coinciding with a plane C C passing through the centre of the boss A.
DD represent the arms placed according to one form of my invention, that is to
say, projecting more or less tangentially from the boss A and standing in planes
parallel to, but at a sufficient distance from, the plane C C to enable the thread E to
pass from the drawing rollers to one of the eyes F without coming in contact with
any part of the flyer arms.
Instead of the arms D D being straight and projecting tangentially from the
boss A, they may be arranged to project in any direction from the said boss, and
the upper parts be bent, or curved, as illustrated in Figure 4, so as to leave room
for the thread to pass to the eyes F without coming in contact with the-flyer arms,
as before described.

page_text: By employing flyers constructed as above described, the breakage of threads
during the process of spinning, is very much reduced, by reason of the absence of
friction between the thread and the flyer arm which is unavoidable with the
ordinary form of flyer.
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
1 claim is
Constructing the flyers for spinning machines so that the parts of their arms
which are more or less at right angles to the spinning spindles shall be either
parallel to, but not coincident with, a plane passing through the centre of the boss,
or be curved so as to leave room for the thread to pass to the eyes of the flyers
without coming in contact with the flyer arms, as herein before described, and
illustrated in the Drawings hereto annexed.
