An Improved Winding Up Apparatus for Lace and other Embroidery.
Machines.
We, REUBEN MANSFIELD, of Hockley Mill Woolpack Lane, Nottingham, Laco
Maker, and ALFRED GODDARD, also of Hockley Mill, Woolpack Lane, in the town
and county of the town of Nottingham Mechanic do hereby declare the nature
of our invention for AN IMPROVED WINDING UP APPARATUS FOR LACE AND OTHER
EMBROIDERY MACHINES to be as follows:-
This Invention consists of an improved means for winding up the fabric on laca.
and other embroidery machines.
Heretofore when fixing the net or when racking up from..breadth to breadth, each
roller had to be. wound up seperate by hand which occupied a deal of time and
attention.
In a lace embroidery machine the net on which the pattern is to be made is
stretched between two rollers fixed in a vertical line and at a convenient distanco
apart: the ends of the said rollers are supported in brackets fixed to a figuring frame,
which frame is moved about to receive the figuring threads as the pattern may
require by the pentagraph which is worked from the end of the machine by an
attendant.
It is usual however to employ two sets of rollers fixed to the same figuring frame,
and in the same vertical line.
The plain material is wound on the lower roller of each set the ends of the
material are fixed by suitable means to the upper roller of each set, and when the
material is sufficiently stretched the said rollers are locked by pauls or clawkers
engaging in the teeth of ratchet wheels fixed thereto. The inachine is then put
into motion and the operation of figuring or embroidering the material
goes
until a breadth is completed-that is the length of one complete pattern or figure-
This breadth is then wound on the upper roller, and the above operation is repeated
for another.
In the above described each roller had to be turned and fixed seperately.
on

page_text: Now our improvements consist essentially in providing apparatus whereby both
sets can be racked up simultaneously or, each set seperate, or, when it is required
that is when the circuinference of one roller exceeds that of the other, and consequently
giving an unequal circumferential travel, each roller of each set may be moved
independant of the other in order to obtain a proper tension on the stretched material
by the hereinafter described means.
One end of each of the upper roller spindles is made to move free in the boss
of a chain wheel and is further provided with a ratchet wheel: the said chain wheel
is provided with a paul or clawker which engages with the teeth of the ratchet wheel
aforementioned: the said paul when in gear with the ratchet wheel causes the
roller to move with the chain wheel, but should it be required to turn either the
lower or the upper roller for the purpose hereinbefore mentioned, the said paul is
thrown out of gear to enable the same being done, and is then locked again.
The chain wheel is provided with a spindle which is produced conveniently to end
of machine and to which is fixed a suitable hand wheel the said chain wheel spindle
is movable in a bracket fixed to the figuring or pentagraph frame.
On the same side to which the above are fixed the lower roller of each set is
provided with a chain wheel, and on the opposite end with a ratchet wheel, a paul for
the same being fixed to the figuring frame.
The upper and lower rollers are then connected by a chain or other suitable
transmitter.
The bottom set of rollers are similar in all details to the top set.
In order to enable us to wind up both sets together in complicated patterns or
from breadth to breadth, we provide each of the opposite ends of the lower roller
of the top set, and the upper roller of the bottom set with a spur wheel: these two
spur wheels can be connected by an intermediate wheel movable upon a stud fixed
to a bracket on the figuring or pentagraph frame: the said intermediate wheel
is so arranged that it can be thrown in or out of gear as may be required.
It will now be seen that in fixing the plain material on the rollers of the figuring
frame, each set can be worked separately.
That when winding or racking up in complicated patterns or from breadth to
breadth both sets can be done at one time by putting into gear the intermediato
wheel aforementioned thus saving a deal of time and labour and
That when it is required to take up any slack in the material caused through the
unequal circumferential travel of the rollers anyone of the same can be moved
indopendently of the others.

page_text: We, REUBEN MANSFIELD of No. 18 Curzon Street Nottingham Machine Holder,
and ALFRED GODDARD of No. 66, Newington Street Nottingham, Machinist, 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 consists of an improved means for winding up the material on
embroidery machines
Heretofore when fixing the material or when racking up from breadth to breadth
cach roller had to be wound up seperate and by hand which occupied a deal of time
and attention.
In an embroidery machine the material on which the pattern is to be worked
is stretched between two parallel rollers fixed horizontally and at a convenient
distance apart the ends of the said rollers are supported in brackets fixed to a
figuring frame, which frame is moved about to receive the figuring threads as the
pattern may require, by the peniagraph which is worked from the end of the machine
by an attendant.
It is usual however to employ two sets of rollers fixed to the same figuring frame.
The plain material is wound on the lower roller of each set, the ends of the
material are fixed by suitable means to the upper rollers of each set, and when
the material is sufficiently stretched the said rollers are locked by pawls which engage
in the teeth of ratchet wheels fixed thereon. The machine is then put into motion
and the operation of figuring or embroidering the material goes on until a breadth
is complote, that is the length of one complete pattern or figure-This breadth is
then wound on the upper roller and the above operation is repeated for another
breadth.
In the above described each roller had to be turned and fixed separately.
Now our improvements consist essentially in providing apparatus whereby both
sets can be racked up simultaneously, or each set separately, or, when it is required,
that is when the circumference of one roller exceeds that of the other and con-
sequentially giving an unequal circumferential travel, each roller of each set may
be moved independant of the other in order to obtain a proper tension on the
stretched material by the hereinafter described means.
One end of each of the upper roller spindles, is made to move free in the boss
of a chain wheel, and each are further provided with a ratchet wheel which are
fixed thereon: the said chain wheels are each provided with a bracket for a pawl,
which pawl engages with the teeth of the ratchet wheel aforementioned: the said
pawls when in gear with the ratchet wheels cause the rollers to move with the chain
wheels, but should it be required to turn either the lower or upper roller of either
set for the purpose aforementioned, the pawl would be thrown out of gear to enable

also spur wheel arrangement for working both sets simultaneously.
Fig. 2 is left hand end view of same, and
Fig. 3 is right hand end view of same.
Fig. 4 (sheet 2) is part elevation of figuring frame, showing chain connection
for working both sots of rollers, also friction brake for regulating the tension.
Fig. 5, (sheet 2) is right hand elevation of same..
The same letters of reference indicate corresponding parts in all the figures.
A is the figuring frame provided with bearing brackets for the work rollers
B and B the frame A is caused to move up or down or laterally as the pattern
being worked on the fabric may require by the pentagraph which is worked by
an attendant at the end of machine, and is common to the trade. O is part of
machine standard.
The spindle C of the roller B is supported in bearings D which are secured to
the frame A a ratchet wheel E is keyed to the spindle C, the said ratchet wheel E
receives its motion from the pawl F which is supported by a bracket G and secured
to the chain wheel H. The end a of the spindle moves free in the boss of the
chain wheel H: the said chain wheel is secured to the spindle I which is supported
by the bracket or bearing J and is provided with a band wheel K.
The roller B (Figs. 1. 2. and 3.) is provided on the left hand and with a chain L
the chains M connects the two rollers B and B'. The right hand: ends of the
rollers B and B are each provided with a spur wheel N and O: an intermediate spur
wheel P provided with a suitable recess for the ends of a forked lever or rod Q
is free to be moved along the stud R which is secured to the bracket S: the rod Q
is supported by the bracket T which is secured to the frame A.

page_text: On reference to Figs. 1. 2 and 3 it will be seen that the upper and lower set
of rollers are the same in detail, and that each can be wound up separately.
In order to tighten or slacken one roller independant of the other, which is
requisite when the circumferential traverse is unequal, the paul F is released from
the wheel E and either the roller B or B' can then be moved separately as required.
Jare ratchet wheels fixed at the right hand end of the rollers, provided with
pawls secured to the figuring frame, for the purpose of locking or keeping in position
the said rollers.
By sliding into gear the intermediate wheel P it will be seen that both sets
can be moved simultaneously, extra leverage being provided at A' for this purpose.
In Figures 4 and 5 (sheet 2) the top rollers B of each set are the same in detail
at the right hand end as those shown in figs. 1. 2. and 3. but instead of the chain
connection being made separately between the top and bottom roller of each set
it is made direct with the the two rollers B. The left hand end of the spindles
of the Rollers B are each provided with a plain friction disc C, the brake lever D'
which movos on the pin E is provided at one end with a wood block F¹ which block
is pressed to or released from the disc C¹ as required by turning the screw G¹
the end of which is secured in the lug of the bracket H' which is secured to the
frame A. It will be seen that by this means both sets can be wound up simultaneously
or one set separate by disengaging either of the pawls F, and that the tension
of the material can be regulated by adjusting the roller B and securing it by means
of the friction brake, or by securing the roller B' and adjusting B. Of course it will
be understood that in winding up in this manner that the motion given to the
top roller of each set will cause the material as it is being wound on to the
rollers B to unwind from the rollers B¹.
It will now be seen that in fixing the plain material on the rollers of the figuring
frame each set can be worked separately; that when racking or winding up in
complicated patterns or from breadth to breadth both sets can be done at one time
either by putting into gear the intermediate spur wheel aforementioned, or by
connecting the upper rollers of each set direct as aforedescribed thus saving
a deal of time and labour and that when it is required to take up any slack in
the material through the unequal circumferential traverse of the rollers anyone
of the same can be moved independent of the others.
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 :-
The use and employment of the means hereinbefore described for winding up
material on embroidery machines all substantially as herein set forth and illustrated
in the accompanying Drawings.
