Improvements in the Construction of Faller Bars and Gills for Gill
Frames.
I, JOSHUA VALENTINE EVES, of Forth River Mill, Falls Road, Belfast, in the
County of Antrim, Ireland, Flax Spinner, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the faller bars which carry the gills in drawing and
other frames known as gill frames for the preparation of flax and wool fibres for
spinning,
The invention is designed to gain lightness and strength in the faller bars.
In order to gain lightness which enables a higher speed of faller to be attained, the
faller is made of trough shaped box shape or tubular or other corresponding
section.
In order to maintain the strength of the bars when made of the ordinary solid
section I bore the bar to receive the rivet only to say about one third of its
depth. I then bore or drill across the bar a hole slightly larger than the river
passing at right angles through the rivet hole. This transverse hole provides an
opening into which punches can be introduced to flatten out the end of the rivet
or otherwise form such a head as will not draw through the rivet hole.
When it is necessary to remove the gills from the faller bar for repair a drill is
run through the transverse hole and the flattened end or head of the rivet is cut
away so that it can be easily taken out.
This method of attachment does not deprive the bar of strength as is the case
when the rivet hole is bored through from top to bottom of the faller bar in addition
to which there is much less wear and tear to both fallers and gills when they have
to be separated for repair as neither punches nor chisels have to be used in the
operation..

page_text: 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 the faller bars which carry the gills in drawing and
other frames known as gill frames for the preparation of flax and wool fibres for
spinning,
The invention is designed to gain strength and stiffness in the faller bars
without any increase of weight.
It consists essentially in attaching the gills to the faller bars by short rivets
inserted in holes extending about one third of the depth of the bar with a cross
hole drilled at right angles into the rivet hole to provide for the securing of the
rivet in the first place and subsequently for removing it
The invention will be fully described with reference to the accompanying
drawings:
Fig. 1. Longitudinal section of part of faller bar.
Fig. 2. Transverse section of same. ***
Fig. 3. Perspective view.
The faller bar A is made of the ordinary solid section and in order to maintain
the strength thereof I bore or drill the rivet holes a to about one third of the
depth of the bar to receive the rivets by which the gills are secured. Across
the bar at each of the rivet holes a I bore or drill a second hole a slightly larger
than the rivet and crossing the end of the rivet hole a at right angles.
The transverse hole a¹ provides an aperture into which a punch or tool can be
introduced to flatten out the end of the rivet or otherwise form such a head as
will not draw through the hole a.
The transverse hole a' also serves for access to the rivet to remove it
When it is necessary to reniove the gills B from the faller bar A for repair a drill
is run through the transverse hole a¹ and the flattened end or head of the rivet b
is cut away so that it can be easily taken out.
This method of, attachment does not deprive the bar of strength as is the case.
when the rivet hole is. bored through from top to bottom of the faller bar in
addition to which there is unich less wear and tear to both fallers and gills when
they have to be separated for repair as neither punches or chisels have to be used in
the operation.
The gills may be riveted on by hand or by a suitable machine.
Having now particularly described and ascertained the nature of the said a
invention and in what manner the same is to be performed. I declare that what
I claim is
1. A faller bar constructed with a rivet hole extending only a part of its depth
to receive the rivet by which the gills are secured and a transverse hole to give
access to the rivet for securing and removing it substantially as described.
2. A faller bar constructed and arranged substantially as described and shown.
