Complete Specification Accepted, 23rd Nov., 1888
I, ARTHUR HARRY BRIGGS, of Brigella Mills, Bradford, in the County of York,
Spinner and Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
The object of this invention is to increase the production of a frame in spinning.
I accomplish my object by running the spindle in a socket fixed in the spindle rail
below the lifter plate, and so arranged as to give a long bearing between the spindle
rail and the lifter plate.
1 secure the wharl on to the spindle giving steadiness to the spindle and enabling
me to increase the speed beyond that which has been accomplished on fly spinning
frames.

page_text: I, ARTHUR HARRY BRIGGS, of Briggella Mills, Bradford, in the County of York,
Spinner and Manufacturer, 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 certain improvements in the method of and apparatus for
Fly Spinning whereby the speed of such spindles is increased from, say 2500 to 4000
revolutions per minute, the production of each frame being increased in that ratio.
It is well known that in Fly spinning the fibre of the yarn is smoother than that
produced in either ring or cap spinning: in both the latter systems the outer fibres do
not lay to and in the direction of the yarn, whereas in Fly spinning the fibres do lay
to the yarn in the direction of its length and for the most part to this difference is
attributable the smoothness of fly spun as compared with ring or cap spun yarn.
The speed however at which either ring or cap spindles can be driven makes the yarn
from both much cheaper than fly spun yarn and the temptation to use ring or cap
spun yarn is in consequence very great.
The object of this invention is to bring the speed of the Fly spindle nearer to that
of ring or cap and thus produce with all its advantages when made up into piece
goods, at about the same price as cap or ring spun yarn and consists in running the
spindle in a socket fixed in the spindle rail below the lifter plate, and so arranged
as to give a long bearing between the spindle rail and the lifter plate and thus give
steadiness to the spindle.
In order that my invention may be more fully understood I will further describe
the same by aid of the accompanying sheet of drawings in which
Fig. 1. represents a front view of my improved spindle.
Fig. 2. is a similar view, part being shewn in section for the purpose of better
illustration.
Fig. 3. is a section through line Y. Z. drawn to a larger scale.
The spindle is indicated by the letter A. but is considerably shorter than hitherto,
the foot of the same A¹ instead of resting in a footstep on the bottom rail of the
frame is carried by the specially constructed internal socket B fitted within the outer
socket C: the latter is secured to the spindle rail D, of the frame by a nut E. on the
underside and the elongated hollow boss F. on the top side forming a base. The
spindle A. revolves in oil contained in the internal socket B. holes G being bored in
the same to communicate with the oil contained in the outer socket C. which also
acts as a reservoir.
This arrangement is one of great advantage inasmuch as the oil is contained and
retained within these receptacles-the outer and inner socks B. and C.-and need not
be changed or removed for months: it is well known that in the old mode of oiling
the footstep and the journal of the spindle that the oil quickly found its way to the
floor which if constructed of wood soon became saturated with oil and in consequence
highly inflammable.

page_text: The spindle A. is. mounted with the ordinary "flyer" H, but made considerably
shorter and therefore lighter than spindles hitherto used in Fly Spinning and towards
the bottom of the said spindle A, I secure a hat or cap J. the spindle A. passing
through the centre of the same; the bottom of the hat or cap J. is formed into the
wharl K. the position of which in my improvement is between the spindle rail D.
and the lifter plate L. thus giving a steadiness which is necessary to the increased
speed of the "fly" spindle.
The elongation of the hollow boss F. resting upon the spindle rail D. passes up
through the hollow wharl K. and into the hat or cap J. secured thereto.
The internal socket B. is made to fit within the outer socket C. and is provided
with grooves M. M. M. which receive one or more steady pins N. secured to the
inside of the outer socket C. and is thereby prevented from revolving with the
spindle A.
The Guard for the driving band and for retaining the wharl in position is of the
ordinary construction and is indicated by the letter O. when it is desired to lift the
spindle from the socket, the said guard O. is pulled back, and when liberated retains
its normal position by means of the spring P. contained in the hollow boss F.
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 :―
The hereinbefore described arrangement of parts as and for the purpose herein
set forth.
Dated this 19th day of October 1888.
