Improvements in Gill Frames for Preparing Flax, Hemp, Jute, and
other Material for Spinning. ;
:
I, DANIEL ANDREW DUGAN, of 228 4th Avenue, in the City of Brooklyn,
County of Kings, and State of New York, United States of America, Foreman,
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 supports for gill bars or "fallers" which are used in
connection with the drawing, and roving frames in machines for preparing flax,
hemp, jute, and similar long fibered substances for spinning, and for what is known
are supported
a "gill spinning." In this class of machines the gill bars or "fallers
"fallers" are
in frames composed of paralel bars or supports, and the gill bars or
arranged to seperate planes one above the other, and the bars or "fallers" of each
plane are carried back and forth, by means of screw threaded shafts arranged in
the sides of the supports, which operate in connection with the end of the bars or
"fallers" to carry them forward and back and this construction is well known and
familiar to those skilled in the art to which this invention relates.
In the operation of the machine as described the gill bars in the upper row or
plane are carried forward by means of screw threaded rods or bars which are
arranged adjacent to the ends thereof and which carry the bars forward by means
of the screw threads formed thereon, and as each bar in the upper row or plane
arrives at the front side of the machine it drops down into the second plane the.
members of which are carried downward by similiar screws threaded which operate
in connection with the ends thereof, and as each of the gill bars drops from the
upper to the lower plane it strikes upon a solid steel support.
1.
These bars are from six to eight pounds in weight and are dropped at the rate
from two hundred to three hundred per minute and the constant hammering and
shaking thus produced loosens the gills and as a tendency to buckle, bend or break
the bars.
Heretofore, as above stated, the bars have been dropped upon a solid steel
support, and the object of this invention is to avoid the objections above specified
by providing a yielding, or spring cushion support, or receiver upon which the gill
bars may drop, and with this object in view the invention consists in the construction
combination and arrangement of parts herein after described and claimed.
The invention is fully disclosed in the following specification..
Fig. 1 represents a front view of a machine provided with my improvement, and
Fig. 2, a sectional view of said improvement.
In the construction shown in the drawing A, designates the paralel supports for
the gill bars, in the adjacent sides of which are formed grooves. or, recesses a. and a¹
below each of which is formed a longitudinal flange or extension, B, which serves
as supports for and on which the gill bars slides.
Arranged in each of the recesses a, and is a shaft C. the ends of which only.
are shown and each of these shafts are screw,threaded and the threads formed
thereon, are adapted to come in contact with the ends d. of the gill bars D which
are free to move back and forth on their supports, B, and it will be understood
that a pluality of these gill bars, D, are arranged in each plane side by side, and it
will also be understood that the view shown in Fig. 1. is: a front view of the
1..

page_text: machine or a section thereof and that but one gill bar of each plane or series
is shown.
In the operation of the machine the bars of the upper plane are each carried
forward and those of the lower plane are carried backward and as each of the bars
of the upper plane reaches the front of the machine it drops down into the lower
plane, and the bars of the upper plane being continually carried forward and dropped
and the bars of the lower plane are continually carried forward and raised at the
rear end or back of the machine into the upper plane.
All the features of construction are well understood and consequently need no
further illustration and description.
As the hars of the upper plane are droped into the lower position they fall
upon the rigid supports, B, as herein before stated and these bars are all of
considerable weight each weighing from six to ten pounds and this constant
hammering loosens the gills or hackles E and also has tendency to break or hend
the bars at the centre.
To avoid this I provide a ccbtral spring support rest or receiver, consisting
of a tubular base F which is connected with the base G of the machine or a cross
bar connected therewith and within the tubular base F, is placed a spiral spring H.
on which rests the shaft K of the receiver or support L which is provided with
side arms M. the upper ends of which are curved outwardly as shown in Fig. 2
and are adapted to receive the bars as they fall from the upper to the lower plane
in Fig. 1.
Formed in the side of the tubular base F is a vertical slot N, through which
passes a pin O. which passes into or through the shaft, K, of the support L, and
which prevents the removal of said shaft from the tubular base as will be readily
understood.
With this construction it will be seen that as each of the bars D drops from
the upper into the lower position it strikes upon the yielding support and the
constant shaking and bending or breaking of the bar is prevented as is also the
loosing of the gills or hackles E. The operation of the machine is also much
sinoother and more even and regular and the frequent stoping and repair made
necessary by the breaking or bending of the bars and the looseing of the gills or
hackles is avoided and consequently much time is saved, and I therefore accom-
plish the object of my invention by means of a device which is simple in construction
and operation and which is also comparatively inexpensive and which is perfectly
adapted to accomplish the result of which it is intended.
It is evident that changes in the forin and construction of my yielding support
or receiver may be made without departing from the spirit of my invention and
1 therefore reserve the right to make all such alterations therein as fairly come
within the scope of the invention.
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. A yielding or cushioned support or receiver for gill bars, substantially as
shown and described.
2. The combination with a machine for preparing flax, hemp, jute, and similar
material for spinning, in which moveable and droping gill bars, are employed of
a yielding support or receiver for said gill bars, substantially as shown and
described.
3. The combination with a machine for preparing, flax, hemp, jute, and similar
material for spinning, in which moveable and droping gill bars are are employed
of a yielding support or receiver for said gill bars, consisting of a tubular base
in which is placed the spring supported shank of the holder or receiver; substantially
as shown and described.
4. The combination with a machine for preparing; flax, hemp, jute and similar
material for spinning, in which moveable and droping gill bars are employed, of a

page_text: yielding support or receiver for said gill bars, consisting of a tubular base in
which is placed the spring support shank of the holder or receiver, said receiver
being provided with side arms which extends upwardly and outwardly and are
adapted to receiver the bars thereon, substantially as shown and described.
