COMPLETE SPECIFICATION.
We, JOSEPH WAGSTAFF, of Pikes Lane Glossop in the County of Derby,
Bandmaker and GEORGE BRADLEY, of the Fleece Inn, Bernard Street, Glossop,
likewise in the County of Derby, Innkeeper, do hereby declare the nature of our
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MAKING
COTTON AND OTHER FIBROUS LOOP BANDS USED IN SPINNING AND OTHER
MACHINERY" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our Invention has for its object improvements in machinery or apparatus for
making cotton and other fibrous loop bands used in spinning and other machinery
and relates more particularly to the construction of machinery for the manufacture
of cotton hands of the kind known as "double loops" that is bands having an
eye or loop at each end the two being connected by means of a small hook when
the band is placed on the spindle.
According to our Invention we employ two sets of rotating spindles each
terminated by a hook, and driven by a pair of bevel wheels, or by other suitable
mechanism. One set of these spindles is mounted in a fixed rail or bearing frame,
and the shaft by which motion is communicated to them is furnished with two
sheaves of different sizes by which it can drive the driving shaft of the other set
of spindles at corresponding speeds. These sheaves are not fixed directly to the
shaft, but can be thrown in and out of gear with it by means of clutches fastened
to the sheaves or instead of clutches fast and loose pulleys or sheaves can be
employed.
The other set of spindles, which is only half as numerous as that just described
is mounted, together with the driving shaft and gear, in a moveable rail or frame,
so that as the length of the band decreases it can move forward towards the fixed
set of spindles. Its motion is regulated by cords running over sheaves and
carrying weights at their extremities. When the frame moves forward these
weights work up. The driving shaft carries two sheaves of unequal size, while two
double sheaves are mounted on an arm or bracket attached to the moveable frame.
The object of these sheaves is to allow the frame to move without appreciably
affecting the tension of the driving belts or bands, each band being carried from
one gallows sheave in a loop or bight round a driving sheave and back to a second
gallows sheave
Between the two sets of spindles there is arranged a carriage running upon
wheels and carrying studs, pins, or projections equal in number to the number of
bands the machine is constructed to make at once. These pins stand between the
two sets of yarns during the twisting process and regulate the final twist, the
carriage being forced forward from the eye, under the regulation of cords and
weights, as the final twist is being accomplished.

page_text: Referring to the accompanying Sheet of Drawings Fig. 1 is an elevation and
Fig. 2 a plan of a machine according to our Invention.
A. A represent a set of spindles each terminating in a hook B, and driven by a
pair of bevel wheels C. These spindles are all mounted in the fixed rail or
frame D. Motion is communicated to them by the driving shaft G which carries
at one end the sheaves E and F. provided with clutches by which either of them
can be connected to the cross shaft G, upon which the bevel wheels are mounted.
H. H.represent a second set of spindles half as numerous as. A. A., and like the
latter furnished with hooks and driving wheels. They are mounted in the
moveable rail or frame I, and are driven by the cross shaft J. The rail I, is held
back by the ropes K and weights L and cannot move forward towards the
spindles A. A without raising the weights.
This ensures a constant tension being maintained on the bands during manu-
facture. The shaft J can be driven at two different speeds by bands from the
sheaves E. F. passing over the sheaves M. N.
To ensure the tension of these bands being maintained constant in spite of the
motion of the frame I each band is carried round a double sheave O mounted on
an arm or bracket, and forms a loop or bight between it and the driving pulley.
P, is a carriage carrying pins Q, and capable of running on rails between the two
sets of spindles, its motion being regulated by cords and weights.

The operation of the machine is as follows:-After the yarn has been placed on
the three spindles in the usual way the set A. A are put in rotation, and are
allowed to run until the necessary number of twists have been imparted to the
half bands. Then one of the sheaves E or F. is connected to the running
shaft G, and the spindles H. H. are put into motion to twist the two half bands
together. As soon as this action commences the frame I begins to advance towards
the spindles A. A. while the carriage P, which had hitherto stood immediately in
front of I, also commences to advance to A. A but at a much quicker speed. Its
office is to ensure the two half bands shall be evenly laid together without cork
screws.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:
In machinery for making cotton or other fibrous bands used in spinning and
other machinery.
1. The use in combination of two sets of driven spindles, one of which is
capable of advancing towards the other without disconnection with the driving
apparatus substantially as described.
2. The use in combination with the driven spindles A. A. and the driven
spindles H. H, of the sheaves M. N, and the gallows sheaves O, O, substantially as
described.
3. The improved machine constructed, arranged and operating substantially as
described with reference to the Drawings.
