IMPROVEMENTS IN AND IN THE MANUFACTURE OF FLYERS
Year: 1884

page_text: I ROBERT NIVIN COTTRILL of the Bee Hive Works, Folds Road Bolton-le-
Moors, in the County of Lancaster, Spindle and Flyer Maker, do hereby declare the
nature of the said invention for "IMPROVEMENTS IN AND IN THE MANUFACTURE
OF FLYERS" to be as follows:-
My Invention relates to the flyers used in the spinning and doubling of textile
materials and in the preparation of the rovings or material used in spinning
machines and particularly to the flyers which have presser arms so applied as to
require bearings at the ends of the flyer legs. Previously to my invention the
presser arm bearing has been formed in a metal fixing which has been secured to
the flyer leg by means of solder and has been liable to become detached. The
object of my invention is to be able to secure this fixing by brazing so as to obtain
greater security but owing to the difficulty in finishing after the brazing this has
not be practicable. To obviate this difficulty I use a fixing which can be securely
brazed to the leg of the flyer and be trimmed and finished before the introduction
of the presser arm.
The fixing is formed with a hollow or jaw to fit upon the flyer
leg and with a jaw to receive the part of the presser arm which usually passes
through the bearing. When the fixing is ready to receive the presser arm and the
latter is in place the lips of the said jaw are pressed or hammered over so as to
meet and to complete the bearing.

I ROBERT NIVIN COTTRILL of the Bee Hive Works, Folds Road, Bolton-le-Moors
in the County of Lancaster Spindle and Flyer Maker, do hereby declare the nature of
the said invention for "IMPROVEMENTS IN AND IN THE MANUFACTURE OF FLYERS
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement and accompanying drawings
-
My Invention relates to the flyers used in the spinning and doubling of textile
materials and in the preparation of the rovings or material used in spinning
machines and particularly to the flyers which have presser arms so applied as to
require bearings at the ends of the flyer legs. Previously to my Invention the
presser arm bearing has been formed in a metal fixing which has been secured to
the flyer leg by means of solder and has been liable to become detached. The
object of my Invention is to be able to secure this fixing by brazing so as to obtain
greater security and at the same time to lessen the difficulty in finishing after the
brazing operation. To obviate this difficulty in finishing I use a fixing which can
be securly brazed to the leg of the flyer and be trimmed and finished before the
introduction of the presser arm.
And in order that the manner in which I carry my Invention into practical
effect may be fully understood I have attached hereto a sheet of drawings wherein
Figs. 1 and 2 represent two forms of the fixing which I use; Fig. 3 shows the
same in position on the leg of the flyer; Figs. 4 and 5 representing cross sections
of the leg. Fig. 6 represents the flyer without the presser and Fig. 7 represents
the complete flyer. Figs. 1 and 2 illustrate two methods of forming the fixing. In
Fig. 1 the fixing a. is cast or shaped with a jaw a¹ to receive the shaft of the
presser arm and is hollowed at the back to fit upon the flyer leg. The fixing is
brazed in position upon the flyer leg and after having been suitably cleaned and
trimmed the presser is applied in position with its shaft within the jaw which is
then closed over the shaft. In Fig. 2 the fixing b. is made by bending a piece of
sheet iron or steel into the indicated form. After the brazing operation the fixing
is sawn or slitted at c. and the eye opened out so as to form a jaw to receive the
shaft of the presser in the manner indicated in Fig. 4. The sides of the jaw are
then pressed together again so as to retain the presser as indicated in Fig. 5.
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 method of securing the presser arm at the lower end of the flyer leg after
the brazing thereon of the fixing which holds the presser arm substantially as and
for the purpose set forth and indicated.
2. In the manufacture of flyers the fixing brazed upon the flyer leg and
receiving the shaft of the presser into a jaw which is closed to retain the said shaft
substantially as set forth and indicated.
