PROVISIONAL SPECIFICATION,
An Improved Method of and Apparatus for Scouring, Drying, and
Stretching Mohair, Alpaca, and such like Warps and Yarns.
I, ARTHUR HARRY BRIGGS, of the firm of 1. Briggs & Co., Briggella Mills,
Bradford, in the County of York, Worsted Spinner, do hereby declare the nature
of this invention to be as follows:-
This invention relates to certain improvements in the treatment of mohair,
alpaca, and such like warps and yarns, and consists of an improved method of, and
apparatus for scouring, drying, and stretching such warps and yarns, the object of
the invention being to develop the lustrous appearance peculiar to mohair, alpaca,
and such like warps and yarns, by one continuous treatment, thereby superseding
the present intermittent and laborious treatment.
The usual custom, in order to produce lustre in mohair, alpaca, and such like
warps and yarns, is to steep the warps and yarns in a series of separate vats or tubs
containing soap suds for some considerable time, after which they are taken out
and squeezed between rollers to remove the soap suds and dirt.
The warps and yarns are then put onto stretching appliances and stretched, and
finally placed in a heated room or chamber to dry.
I accomplish my object as follows.
I place the warps or yarns on a beam, and conduct the threads or "ends" of
same by means of rollers, each and every thread being separate, through a series
of vessels containing soap suds and water. After being thus scoured the threads
of the warps or yarns pass over a series of drying cylinders heated by steam which
effectually dry and stretch the material, and give to the same a lustrous appearance,
which has hitherto been thought only obtainable by steeping and subsequent treat-
ment as previously described, the essential feature of my invention being the
separation of the threads of the warps or yarns and the continuous treatment of the
same.
Dated this 10th day of December 1890.

COMPLETE SPECIFICATION.
An Improved Method of and Apparatus for Scouring, Drying, and
Stretching Mohair, Alpaca, and such like Warps and Yarns.
I, ARTHUR HARRY BRIGGS, of the firm of I. Briggs & Co., Briggella Mills,
Bradford, in the County of York, Worsted Spinner, 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:-

onto stretching appliances, and finally placed in a heated chamber to dry.
In the accompanying drawings,
Fig. 1 represents a side elevation of my machine for producing lustre by
scouring, stretching, and drying, in mohair, alpaca, and such like warps and
yarns,
Fig. 2 is a plan of same,
Fig. 3 a longitudinal section with certain parts of the gearing added, and
Fig. 4 a cross section on line Z Z in Fig. 1.
The warps or yarns to be treated are mounted on a beam A, each and every
thread being separate, and are drawn through a series of vessels B, containing soap
suds. After being thus scoured, the threads are stretched as hereinafter described,
and then passed over a series of drying cylinders C, finally passing out between the
rollers D; the direction taken by the threads of the warp or yarn through the
machine being denoted by arrows.
The vessels B are provided with rollers E, at the bottom of each, under which
the threads of the warps or yarns are conducted, and between each vessel I have a
pair of squeezing rollers F and F', the upper roller in each case being driven by
frictional contact from the lower one.
The upper rollers F, are weighted by means of levers with weights, or their
equivalents, so as to effectually squeeze the dirt and suds from the warps or yarns.
The drying cylinders C are steam heated, the steam entering through the trunnions
at one end, and the water formed by condensation being taken out at the opposite
end, by means of suitable draining arrangement, the steam and water being con-
ducted through channels cast to the side frames G. Guide rollers H are fixed
behind the drying cylinders C, so that the largest circumferential area of the latter
may be utilized. The drawing off rollers D are provided with a screw adjustment,
so that they may be tightly pressed together.
The machine is driven by any suitable motor connected to a shaft J, which by
spur gearing drives a shaft K, this latter by bevel gearing driving the shaft L,
the rollers F¹ being driven from this latter shaft by bevel gearing M. From the
shaft L by spur gearing, I drive the shaft N, which by bevel gearing drives the
shaft O, this shaft by spur-gearing driving the drying cylinders C, which are
driven slightly faster than the squeezing rollers F and F¹, in order to get the
stretch or tension required on the warps or yarns.
The spur wheels of the drying cylinders are geared together by means of inter-
mediate wheels P, whereby they all travel in the same direction. The drawing off
rollers D are driven by spur wheels Q and Q¹ gearing with the wheels of the lower
drying cylinders.
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:
Scouring, stretching, and drying mohair, alpaca, and such like warps and yarns,
by one continuous process, by drawing the threads which are separated through the
vessels B containing soap suds, around the drying cylinders C the threads being
still separated, and finally through the drawing off rollers D, substantially in the
manner as shown and described.
