I, ROBERT ANDREWS, of Bessbrook, in the County of Armagh, Ireland, Flax
Preparing Master, do hereby declare the nature of the said invention for
IMPROVEMENTS IN DRAWING OR PREPARING FRAMES," to be as follows:-
My said Invention has for its object improvements in drawing or preparing
frames for treating flax, jute, or other similar fibres and is especially designed as a
modification of my Invention described in Letters Patent granted to me for
Improvements in Drawing or Preparing frames," dated the 26th November, 1881
No 5170 In the said Letters Patent, I described a certain mode of operating the
fallers and gills for the purpose of removing dirt or fibrous substances therefrom
without stopping the frame. In practice I have found this method to work well,
but rather expensive in its application; and I now propose the following arrange-
ment to accomplish the same object in a moro economical manner.
Instead of utilizing the lower spiral or screw for the purpose of causing the
fallers to assume a horizontal plane, I remove part of the bottom slides on which
the fallers travel, and introduce underneath the ordinary lower spiral or screw at
each end of the head a tappet which for convenience I call a "wiper tappet."
These wiper tappets revolve in combination with suitable segmental or curved
slides arranged and operating in such a manner that the fallers are received from
the bottom spiral or screw on to the periphery of the wiper tappet and carried
round a certain distance, assuming a horizontal position in their course, to a point
where the heel of the faller runs into a recess provided in the segmental or curved
slides. Simultaneously with its entrance to this recess the face of the faller is
acted upon by the wiper tappet, and again tilted into the vertical position and
immediately restored to its ordinary travelling plane in the bottom or lower
Bcrew.
While the fallers are thus being carried round by the wiper tappet through the
seginental or curved Slides they are brought in contact with a revolving brush
arranged in a suitable manner and thereby thoroughly cleansed of any dirt or
fibrous substances adhering thereto.

page_text: I, ROBERT ANDREWS, of Bessbrook, Armagh, do hereby declare the nature of the
invention for "IMPROVEMENTS IN DRAWING OR PREPARING FRAMES," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
EC
My said invention has for its object improvements in drawing or preparing
frames for treating flax, jute, or other similar fibres; and is especially designed as
a modification of my Invention described in Letters Patent granted to me for
Improvements in drawing or preparing frames," dated 26th November, 1881,
N° 5170. In the specification filed in pursuance of the said Letters Patent,
I described a certain inode of operating the fallers and gills for the purpose of
removing dirt or fibrous substances therefrom, without stopping the frame. In
practice I have found this method to work well, but rather expensive in its.
application; and I now propose the following arrangement to accomplish the
same object in a more economical manner.
Instead of utilizing the lower spiral or screw for the purpose of causing the
fallers to assume a horizontal plane, I remove part of the bottom slides, on which
the fallers travel, and introduce underneath the ordinary lower spiral or screw at
each. end of the head a tappet which, for convenience, I call a "wiper tappet."
These wiper tappets revolve in combination with suitable segmental or curved
slides, arranged and operating in such a manner that the fallers are received from
the bottom spiral or screw as they travel along the bottom slide by the teeth on the
periphery of the wiper tappet, and carried round a certain distance through the
segmental slides assuming a horizontal position in their course to a point where
the beel of the faller runs into a recess provided in the segmental slides. Simul-
taneously with its entrance to the recess the face of the faller is acted upon by
the wiper tappet and again tilted into the vertical position, and immediately
restored to its ordinary travelling plane in the bottom or lower screw.
While the fallers are being thus carried round by the wiper tappet through the
segmental slides, they are brought in contact with a revolving brush arranged in
a suitable manner, by which means they are thoroughly cleansed of any dirt or
fibre adhering thereto.
For the purpose of placing the fallers in positive position under the teeth of the
wiper tappets, so as to ensure the certainty of their being carried into the
segmental slides, I arrange a rocking lever over the tappets in such a way that it
is caused to rock by pins placed in suitable positions on the tappets; so that when
the faller is brought back far enough on the lower slide one end of the rocking
lever is caused to press on the head of the faller, thereby ensuring that it comes
under the teeth of the wiper tappets.
In order that my said invention may be more fully understood and carried into
practice, I will describe the accompanying drawings:-
-
Fig. 1 represents a sectional elevation of part of an ordinary screw or spiral used
in drawing or preparing frames, showing my improved apparatus applied thereto;
and fig.
shows my improved apparatus in. detail, as hereinafter more fully
described. band 6' are the upper and lower ordinary screws or spirals; c are the
fallers, and c¹ the gills attached thereto; d is the wiper tappet revolving on shaft c
carried in suitable bearings; f is the rocking lever which swings on a pivot g fixed
to the inside of the upper slide; h is a projection formed on the face of the rocking
lever for the purpose hereinafter described; i is the upper, and j the lower, slide;
kis the revolving brush for cleaning the gills as the fallers pass through the
segmental slides.

page_text: Now the action of my invention may be thus described :-The fallers drop from
the upper to the lower screw or spiral, and are carried along the lower slide in the
ordinary manner. As each faller approaches the wiper tappet it is acted upon by
the narrow end of the rocking lever and pushed into the segmental slide, when,
immediately, the tooth or point p of the wiper tappet, moving in the direction of
the arrow, engages the faller, carrying it round and thrusting it into the recess 7.
At this moment it is again tilted into an upright position by the point p, still
acting on its face (see fig 2), and is restored to the lower slide by the tooth r acting
on its heel. While approaching the recess the gills of the faller are brushed by
the revolving brush which rotates in the opposite direction to that in which the
fallers move.
The action of the wiper tappet on the rocking lever is obvious.
Pins are inserted at suitable intervals on the tappet, so that at the moment the
faller comes under the free end of the lever one of the pins riding along the
projection causes the lever to press down the faller in the manner already
described. The projection is constructed in such a form that as soon as one of
the pins of the tappet leaves the straight end of the projection, the next pin on
the tappet has come far enough round on the projection to carry the free end
of the lever up high enough to admit of the lower screw or spiral bringing the
next fallen under control.
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
I claim is:
(1) The use, in drawing or preparing frames, of a revolving or wiper tappet
acting in combination with a segmental or curved slide, constructed and employed
in the manner, and for the purpose substantially as herein described and set forth.
(2) The use in drawing or preparing frames of fallers and gills, turned
horizontally, substantially in the manner, and for the purpose herein described and
specified.
(3) The combination of parts formed by the revolving or wiper tappet, the
segmental or curved slide, the rocking lever, and the revolving brush, all con-
structed, arranged, and operating in the manner, and for the purpose substantially
as hereinbefore described and set forth.
