PROVISIONAL SPECIFICATION.
Improved Apparatus applicable to Machines for Winding Silk or
other Yarn on Brass Bobbins employed in Twist Lace Machines.
I, JAMES WINFIELD, Long Eaton, Derbyshire, Lace Manufacturer, do hereby
declare the nature of this invention to be as follows:-
To each machine employed in winding silk or other yarn on brass bobbins
employed in twist lace machines I arrange the sley usually placed between the
counting roller and the winding spindle so that a traverse is given it at a right
angle to the length of the winding machine. This I effect by the following means.
The bottom of the sley projects through and slides in a slot in the bed or platform
of the machine, below which the projecting portion is hinged or otherwise connected
to the inner end of a connecting rod, the outer end of the rod is capable of adjust-
ment on one end of a lever rocking on a stud beneath the bed, by which the length
of traverse of the sley is regulated, the other end of the rocking lever is forked and
clips an eccentric on the lower end of a vertical shaft revolving in bearings secured
to the machine the upper end of the shaft carries a toothed pinion wheel driven by
a worm on one end of the winding spindle.
By such means the silk or other yarn is evenly wound on each bobbin and
clears itself as fast as it is unwound thus avoiding the costly waste heretofore
experienced.

COMPLETE SPECIFICATION.
Improved Apparatus applicable to Machines for Winding Silk or
other Yarn on Brass Bobbins employed in Twist Lace Machines.
I, JAMES WINFIELD, Long Eaton, Derbyshire, Lace 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 :-
Up to the present time it has been customary in twist lace machines to use brass
bobbins having an extremely narrow aperture. After winding these bobbins they
have to be pressed before they are sufficiently narrow for use in the machines.
The silk or other yarn on these bobbins as wound thereon by the methods in use up
to the present time becomes displaced by the pressing causing it frequently to
become fast and break in the bobbins. This produces defects in the lace, waste of
silk or other yarn, and causes delay in manufacture, expense in clearing and getting
the bobbins again fit for use, and considerably increases the cost of mending and
making good the defects in the lace.
By my invention I remedy this by causing the silk or yarn during the process of
winding on the bobbin to be traversed so that it lies evenly over the whole width of
the bobbin in each layer. When so wound there is no tendency to its becoming
fast and thereby breaking.
I will now proceed to describe the apparatus by which I propose to effect this
and will do so by reference to the drawings filed with this Specification.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a left side view of portion of a winding machine sufficient to illustrate
my invention.
Figure 2 is a plan of the same.
To each machine employed in winding silk or other yarn on brass bobbins
employed in twist lace machines, I arrange the sley A usually placed between the
counting roller B and the winding spindle C so that a traverse is given it at a
right angle to the length of the winding machine.
This I effect by the following means. The bottom of the sley projects through
and slides in a slot in the bed or platform A' of the machine, below which the
projecting portion is hinged to the inner end of a connecting rod A2, the outer end
of the rod is hinged to a boss A³ provided with a set screw by which it is adjusted
on one end of a lever D rocking on a stud secured to the underside of the platform.
The other end of the lever terminates in a fork D' which clips an eccentric E
secured on the lower end of a vertical shaft E' revolving in bearings secured to the
machine.
The upper end of the shaft E¹ carries a toothed pinion wheel E2 driven by
a double threaded worm C' secured on one end of the usual winding spindle C,
each revolution of the eccentric causes the sley A to be traversed to and fro.
If a quicker traverse of the sley A is required 1 obtain it either by increasing
the number of threads on the worm C¹ or by reducing the number of teeth on the
pinion wheel E2 and enlarging the diameter of the worm.
The counting apparatus operated by the spindle of the roller B being of the
usual construction is omitted in the drawings.
The movements of the apparatus in combination with a winding machine are as
follows: The silk or other yarn F is passed from the main drum which is not
shown in the drawings being of the usual construction, beneath two guide rods or
rollers B', over the cloth or velvet covered counting roller B in the usual way,
through the sley A to the brass bobbins G carried by the usual square spindle C
each revolution of the eccentric by traversing the sley A will cause each coil of
the silk or other yarn to be evenly wound on each bobbin without being trapped
between previous coils.
The bobbins when filled with yarn as shown at Figure 2, when taken off the
winding spindle and the yarn being cut to sever it from the yarn on the main
drum, are steamed and pressed in the usual way then when entered in their
carriages and placed in the lace machine, the yarn on each bobbin will clear
itself as fast as it is unwound while being worked up in the machine, thus avoiding
the breakage and costly waste heretofore experienced.
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 employment of traversing machinery in the winding of silk or other yarn
on bobbins to be used in twist lace machines substantially as herein described.
2. The construction and employment of the apparatus herein described and
illustrated in the drawings annexed for the purposes specified.
