PROVISIONAL SPECIFICATION.
Improvements relating to the Rollers of Spinning Machines and
the like.
'
We, JOHN MADDOOKS, of 26, Booth Street, Manufacturer, and WALTER CHARLES
WHITEHEAD, of Frizinghall, Spinner, both in Bradford in the County of York, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to the front rollers of spinning, roving and twisting machines,
and has for its special object to render the same more suitable than heretofore for
spinning union and fancy yarns from silk, wool, cotton, jute, mohair, alpaca and other
fibres either alone or in combination.
According to our invention we place beside each of the ordinary bosses of the front
roller an auxiliary boss which is free to rotate independently of the ordinary boss.
The auxiliary bosses are advantageously driven from an intermediate shaft by
means of sprocket wheels and chains, the said shaft being placed between the front
rollers and the cylinder.

COMPLETE SPECIFICATION.
Improvements relating to the Rollers of Spinning Machines and
the like.
We, JOHN MADDOCKS, of 26, Booth Street, Manufacturer, and WALTER CHARLES
WHITEHEAD, of Frizinghall, Spinner, both in Bradford, in the county of York, 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:
Our invention relates to the front rollers of spinning, roving and twisting machines,
and has for its special object to render the same more suitable than heretofore for
spinning union and fancy yarns from silk, wool, cotton, jute, mohair, alpaca and
other fibres, either alone or in combination.
According to our invention we place beside each of the ordinary bosses of
the front roller an auxiliary boss, which is free to rotate independently of the
ordinary boss.
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawings, in which-
Figure 1 is a sectional end elevation of so much of a throstle spinning machine as
is necessary to show the application of our invention thereto.
Figure 2 is a sectional plan of the low front roller-bosses; and,
Figure 3 is a similar view of the corresponding presser rollers.
Figure 4 is a view of a detail.
a is the frame of the machine; b, b are the lower front roller-bosses, which are
mounted on the shaft c and adapted to rotate therewith; d, d are presser rollers
loosely mounted on the shafts e, e and covered with leather or other suitable material;
f; fare drawing rollers, and f₁ is a spindle, all the said parts being of ordinary
construction.
9, 9 are the auxiliary bosses, which, according to our invention, are arranged
beside the bosses b, b; and h, h are auxiliary presser rollers, similar to the rollers d, d,
running freely on the shafts e, e in conjunction with the rollers g, g. The rollers g, g
are advantageously driven in pairs, through the medium of a gear-wheel i, as shown

page_text: .
in figure 2, the roller-bosses being carried upon the hub j of the said wheel which
is elongated upon both sides. Motion is communicated to the gear-wheels i from
gear-wheels on an intermediate shaft k, as indicated in figure 1.
It is obvious that, as the bosses 6, 6 are driven by the shaft c and the auxiliary
bosses g, g from the shaft k, the bosses b and g may be driven at any required speeds
relatively to each other. The two yarns to be twisted can thus be delivered at their
proper relative speeds in the manner described in the complete specification of our
application for Letters Patent, dated October 12 A.D. 1888 No. 14700.
The drawing rollers or other rollers through which the threads pass may be
divided or arranged in conjunction with auxiliary rollers in the manner hereinbefore
described.
The yarns or threads passing over each pair of rollers are led to a single spindle
and thereby twisted together.
Although we have described our improvements as applied to a throstle spinning
machine it is to be understood that they are equally applicable to roving, doubling
and twisting machines and to mule spinning machines working on what is known as
the French system.
It is also to be understood that our improved mechanism is applicable for
making union yarn that is to say, a yarn the interior or core of which is of
lower quality than the exterior or covering; and looped, Astrachan and other fancy
yarns.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a spinning machine, the combination with the ordinary bosses or rollers, of
auxiliary bosses arranged beside the same and adapted to deliver the yarns or threads
to be twisted or united at any desired speeds relatively to each other, substantially as
set forth.
2. The improvements in spinning machines hereinbefore described and illustrated
in the accompanying drawings, for the purposes specified.
