page_text: LETTERS PATENT to Sidney Emsley, Agent, of Bradford, and Samuel
Smith, Machine Maker, of Low Bridge Works, Keighley, both
in the County of York, for the Invention of "IMPROVEMENTS IN

FIBROUS SUBSTANCES."
Sealed the 19th January 1875, and dated the 27th November 1874.
COMPLETE SPECIFICATION filed by the said Sidney Emsley and
Samuel Smith at the Office of the Commissioners of Patents,

page_text: WHEREAS we are in possession of an Invention for "IMPROVEMENTS
IN APPARATUS FOR SPINNING AND TWISTING WORSTED, COTTON, SILK, OR OTHER
FIBROUS SUBSTANCES," and have petitioned Her Majesty to grant unto
us, our exccutors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that we verily believe
ourselves to be the first and true Inventors thereof.
NOW KNOW YE, that we, the said Sidney Ensley and Samuel Smitlı,
do hereby declare that the following Complete Specification, under our
hands and seals, fully describes and ascertains the nature of our said
Invention, and the manner in which the same is to be performed,
reference being had to the Drawing hereto annexed, and to the figures
and letters marked thereon, that is to say :-
This Invention relates to improvements in spindles for spinning and
twisting, and consists in the employment of a tube working on a fixed
spindle for friction purposes, the bobbin turning loosely on the tube, and
the tube driving the flyer.
To make our Invention better understood we will proceed to describe
the same by reference to the accompanying Drawing, in which Figure 1
represents a sectional elevation of our improved spindle; Figure 2, front
elevation; Figure 3, side view, and Figure 4, plan of the same; Figure 5
represents the under side of the plate or disk with a section of the
lock.
A, fixed spindle having a bearing piece B fitted in the spindle rail
and firmly fixed by a set screw; upon this spindle A is fitted a tube C
made of sufficicnt length to allow for the traverse of the bobbin D,
as in ordinary throstle spindles. The tubo C drives the flyer E by
means of the opening F in which fits the lock G formed on the short
spindle H of the flyer E. The lugs I forming the sides of the opening F
coming in contact with the lock G produce a locking of the tube C
with the lock G formed on the short spindle H of the flyer E, thus
giving a positive rotary motion to the flyer. The top of the fixed
spindle A is made hollow forming a socket for the short spindle H;
this spindle bears only on the point J and rotates on it, preventing
any bearing of the flyer on the tube C, leaving an opening K between
the tube and the flyer. On the top of the lock G is formed a collar L

page_text: and a screw M on which is fitted a plate or disk N having openings O
through which passes the thread P on its passage to the bobbin D,
confining the thread to the centre, and enabling the twist to arrive
more effectually at the delivery of the roller, and preventing long fibres
from catching the thread in its passage to the bobbin, or what is known
in the trade as hanging of the thread. The plate or disk N is secured
by means of the boss Q of the flyer E, being secured on to the screw M,
and firmly fixed between the collar L and boss Q. The tube C receives
its rotary motion by means of the wharle R, and we employ a washer W
to reduce the friction between the wharle and its bearing.
We employ a lifter plate as in the ordinary throstle spindles, or wo
may use one constructed as herein-after described and represented in
the annexed Drawing. S is a lifter plate made to regulate the tension
or drag of the bobbin, and is provided with a movable top plate T
actuated by two eccentrics worked by gear fitted to a rack fixed to
the spindle rail. On the bottom plate are formed bosses U on which
are placed washers V giving more or less friction. When the bobbin
commences to be formed the washer V rests on the movable plate T,
as represented in Figure 2, and as the bobbin becomes heavier by being
filled the plate T descends and the bobbin rests on the boss only, as
represented in Figures I and 3, thereby giving less friction through the
washer having less surface to work on.

page_text: Fourthly. The employment of the plate or disc enabling the twist to
arrive more effectually at the delivery of the roller, substantially as herein-
before described and represented in the annexed Drawing.
In witness whereof, we, the said Sidney Emsley and Samuel Smith,
have hereto set our bands and seals, this Twenty-sixth day of
November, in the year of our Lord One thousand eight hundred
and seventy-four.
