Improvements in and relating to Warp Balling Machines.
I, JOHN HURTLEY, of Sunny Bank, Burnley, in the County of Lancaster,
of the firm of Robert John Hurtley and Son, Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention is designed to effect a more uniform adhesion of the ball to the
drum during the process of balling.
The usual method has been by weighted pressure applied to the ends of the
arbor or spindle passing through the centre of the ball, by which method an uneasy
and jerky motion is imparted by the lapping of the chain whilst balling.
My improvements consist in the application, of a frictional or drag like arrange-
ment, in such a manner, that as the ball is gradually increasing in size it overcomes
the frictional appliance and accommodates itself during the shifting action of the
arbor or spindle on which the ball is mounted.
The frictional apparatus may consist of a pair of toothed racks in the ends of
which the arbor or spindle is journalled.
The racks gear with two pinions fixed to a cross shaft carrying a wheel to which
the required friction or drag is imparted by a weighted. break lever.

Improvements in and relating to Warp Balling Machines.
1, JOHN HURTLEY, of Sunny Bauk, Burnley, in the County of Lancaster,
of the firm of Robert John Hurtley and Son, Manufacturers, 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 is designed to effect a more uniform adhesion of the ball to the
drim during the process of balling.
The usual method has been by weighted pressure applied to the ends of the
arbor or spindle passing through the centre of the ball, by which method an uneasy
and jerky motion is imparted by the lapping of the chain, whilst balling.
My improvements consist in the application of a frictional or drag-like arrange-
ment, in such a manner, that as the ball is gradually increasing in size, it overcomes
the frictional appliance, and accommodates itself during the shifting action of the
arbor or spindle, on which the ball is mounted.
The frictional apparatus may consist of a pair of toothed racks, in the ends of
which the arbor or spindle is journalled. The racks gear with two pinions fixed
to a cross-shaft carrying a wheel, to which the required friction or drag is imparted
by a weighted brake lever.
In the accompanying drawings, the warp balling machine is represented as con-
sisting of two parts Figs. 1 and 2, which are sectional elevations taken through the
centre of the machine. These parts may be placed nearer to or farther from each
other in accordance with the length of stretch desired.
A is a yarn roller taken from a beaming-frame and deposited at B in the
framing C. The warp or yarn from this roller is taken over guide-roller D, and.
downwards behind bar E, which is bent in concave form to gradually contract the
width of the sheet of warp threads passing from roller A. The warp is further
contracted in its width in passing the bar E', which is also bent in a concave

page_text: manner for this purpose. The warp now passes under roller F, and upwards over
a glass block E, its contracting surface being also concave, bringing the width of
the warp to about three or four inches, when it is then passed under pulley H and
over pulley I, and partially embracing drag-pulley J, is then passed under pulley K
and over pulley L to the eyes M' and N of the traversing levers Mand N. These
levers are mounted at O, as seen in Fig. 2, and are connected together by the tie-
bolt P, and are actuated laterally in a to-and-fro manner by the crank disc Q,
which is connected by the connecting arm R to a lever M² secured to, and
branching at right angles from, the traversing lever M.
The contracted sheet of warp threads, after passing through the contracted
medium described in relation to Fig. 1, is then conveyed through the eyes of the
traversing levers M and N, which guide the warp or chain from one side to the
other of the spindle S, forming a lap backwards and forwards over the surface of
the revolving ball of warp T, which is in frictional contact with the driving drum U,
actuated in the ordinary manner.
I will now describe the arrangement employ for effecting
a more uniform
adhesion of the ball of the warp T to the driving drum U during the process of
balling. V is a shaft mounted in stationary bearings at each side of the machine,
and having at one end a brake wheel G provided with a weighted brake lever G.
To this shaft is also fixed a pair of toothed wheels W, one on each side of the
machine. These wheels gear into side racks X, which lie horizontally, one on each
side of the framing of the machine, and which carry at their outer extremities the
ball-spindle S, in such a manner that as the ball of warp is gradually increasing in
diameter, it pushes back the racks X, so as to overcome the frictional resistance,
applied to the brake-wheel G by the brake-lever G¹. More or less frictional
resistance may be imparted as desired for the various classes of warps undergoing
the process of balling, by moving the weight Y farther from, or nearer to, the
fulcrum of the brake-lever G.
In its finished form, the ball of warp is much superior to those formed by the
ordinary process, being firmer, more compact and less susceptible of "bulging."

Although have described only one yarn roller as being used, two may be
employed, if desired, as seen in Fig. 3, in which case, the yarn or warp threads
from both yarn-rollers are built up in ball-form. To arrest instantaneously the
momentum of the two rollers and prevent an overrun of the warp, the wedge-piece Z
may be inserted between the peripheries of the two flanges A' and A². By this
means, I am enabled to dispense with the rising and falling rollers, which would
otherwise be required to take up the slack warp, the result of an over-run.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
A warp balling machine, in which the ball is gradually forced back against the
frictional resistance or drag as it increases in diameter substantially as described
and illustrated in Fig. 2.
