IMPROVEMENTS IN TAKE OFF OR WINDING UP APPARATUS FOR BOBBIN NET, TWIST OR OTHER LACE MACHINES
Year: 1884

page_text: I EDWARD COPE of Lenton Firs Lenton Nottingham in the county of the same
name Lace Manufacturer, do hereby declare the nature of my said invention for
IMPROVEMENTS IN TAKE OFF OR WINDING UP APPARATUS FOR BOBBIN NET, TWIST
OR OTHER LACE MACHINES to be as follows:-
The objects of my invention are to so construct take off or winding up apparatus
that lace is taken from the loom and delivered to the winding up bar or roller at
the disired speed with uniformity and regularity, the speed of take off is readily
adjusted, and the quantity of lace woven accurately measured.
In practise I make a take off roller with indipendent measuring and gripping
surfaces, I vary the speed of the take off roller by means of change wheels and I
measure the length of lace delivered to the winding on bar by means of indicating
or counting mechanism operated by the taking off roller.
Taking off rollers under my invention are constructed with a measuring surface
obtained by turning a metal or other sufficiently hard roller truly cylindrical and
with a gripping surface obtained by inserting wire cards or other suitable materials
or substances having projecting points or gripping surfaces into helical or other
grooves cut or formed in the roller the said gripping surfaces being allowed to
project slightly above the measuring surface.
Motion is given to the taking off roller by means of change wheels of diameters
corresponding to the various speeds at which it is required that the said take off
roller should move in order to take off and deliver to the wind up roller, lace at
any required speed.
The indicating or counting mechanism is of any usual or desired construction
and is actuated from the take off roller by ratchet, excentric, toothed or like gear.

page_text: I EDWARD COPE of Lenton Firs Lenton Nottingham in the county of the same
name Lace Manufacturer do hereby declare the nature of the invention for
IMPROVEMENTS IN TAKE OFF OR WINDING UP APPARATUS FOR BOBBIN NET OR
TWIST OR OTHER LACE MACHINES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The objects of my invention are to so construct take off or winding up apparatus,
that lace is taken from the loom and delivered to the winding up bar or roller at
the desired speed with uniformity and regularity: the speed of take off is readily
adjusted and the quantity of lace woven accurately measured.
In practise I make a take off roller or beam, hereinafter called roller, with
independent measuring and gripping surfaces; I vary the speed of the take off
roller by means of change wheels or equivalent mechanism, such as adjustible
ratchet gear; and I measure the length of lace delivered from the take off roller by
means of indicating or counting mechanism opperated by the said taking off roller.
Taking off rollers under my invention are constructed, with a measuring surface
obtained by turning a metal or other sufficiently hard roller truly cylindrical, and
with a gripping surface obtained by inserting wire cards or other suitable materials
or substances having projecting points or gripping surfaces into helical or other
grooves cut or formed in the roller; the said gripping surfaces being allowed to
project slightly above the measuring surface.
Motion is given to the take off roller by means of change wheels of diameters
corresponding to the various speeds at which it is required that the said take off
roller should move in order to take off and deliver lace at any required speed.
The indicating or counting mechanism is of any usual or desired construction and
is actuated from the take off roller by ratchet excentric toothed or like gear.
Fig 1 is an end elevation and fig 2 a back view of part of a bobbin net or twist
lace machine fitted with my improved apparatus and fig 3 is a transverse.section
of the take off roller. a framework, b shaft carrying take off roller and fitted with
the worm c and worm wheel d The take off roller is of suitable metal such as iron
or steel and is made with a smooth cylindrical measuring surface e and with helical
grooves or recesses f, wherein are secured wire cards g, the points of the wires in
which project slightly above the surface e Instead of wire cards emery or other
gripping surfaces might be used and the grooves or recesses of might be parallel to
the length of the roller as shown in fig 4 instead of being helical.
The roller h on which the lace is wound.up is carried on swinging links i or may
be held in suitable slots. The shaft a receives motion through the worm wheel d
by means of the worm ; on the shaft k the shaft is carried at each end in
adjustible bearings l. m, n driving gear. The wheels of the gear m or n or both
are changed according to the speed at which it is desired to take off or wind up the
lace. It will be obvious that the driving gear may be considerably modified as
long as it provides for the use of change wheels or adjustible speed gear.

page_text: The worm c on the shaft a gives motion to an indicator o of any usual con-
struction so that the amount of lace wound up it may be ascertained at any time
without measuring.
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
First In bobbin net or twist or other lace machines a take off roller having
measuring and gripping surfaces combined as herein set forth.
Second The combination with take off rollers under my invention of change
wheels or equivalent driving gear.
Third The combination of take off rollers under my invention with counting and
indicating mechanism.
Fourth In bobbin net or twist or other lace machines: the combination of take
off roller, change wheel or equivalent driving gear and counting and indicating
mechanism.
