Improvements in Rolling Machines for Stripping Cloth off Cropping
Machines.
1, WILLIAM SCOTT, Jr. of Mid Wynd Works, Mid Wynd, Dundee, in the County
of Forfar, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
My invention of improvements in rolling machines, refers to those used for stripping
the cloth off cropping machines, used in the manufacture of textile fabrics.
The first part of my invention is the uptake motion, similar to that used in loomis
and consisting of a roller, the surface being studded with a number of projecting pins
for drawing the cloth off cropping machine.
This roller is driven by suitable toothed wheel gearing and at the desired speed,
from the cropping machine.
The driving wheel of roller is attached to its arbor and is kept from revolving by
means of a friction plate, and screw adjusting arrangement, similar to that used in
dressing machines; the object being to keep a uniform tension upon the cloth.
Upon the other end of roller arbor is a measuring apparatus, actuated by means of
screw and screw wheel.
The second part of my invention is the method of taking the filled roller out of the
machine.
Running upon the uptake roller is another upon which the cloth is rolled.
This roller is driven by the friction between it and the uptake roller, and as it
becomes filled with cloth its arbor rises in guide slots at each side of machine.
The one cheek of each slot is made part of the side frame, the other cheek being
made with a hinge at the bottom and capable of being secured at the top with a clasp,
hinged to the fixed cheek.
When the cloth roller is filled, the clasp is unfastened permitting the moveable
cheek to fall down and rest upon the floor or upon a carriage; the cloth roller being
then rolled down the incline formed by said moveable cheek, and deposited where
equired.

Improvements in Rolling Machines for Stripping Cloth off Cropping
Machines.
1, WILLIAM SCOTT Jr., of Mid Wynd Works, Mid Wynd, Dundee, in the County
of Forfar, Manufacturer, 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 :—
My invention of improvements in rolling machines, refers to those.used for stripping
the cloth off cropping machines, used in the manufacture of textile fabrics.
The first part of my invention is the uptake motion, similar to that used. in looms,
and consisting of a roller, the surface being studded with a number of projecting pins
for drawing the cloth off cropping machine.
This roller is driven by suitable toothed wheel gearing, and at the desired speed,
from the cropping machine.
The driving wheel of roller, is on its arbor and is kept from revolving by means of
a friction plate, and screw adjusting arrangement, similar to that used in dressing
machines; the object being to keep a uniform tension upon the cloth.
Upon the other end of roller arbor is a measuring apparatus, actuated by means of
screw, and screw wheel.
The second part of my invention is the method of taking the filled roller out of the
machine.
Running upon the uptake roller, is another upon which the cloth is rolled.
This roller is driven by the friction between it and the uptake roller, and as it.
becomes filled with cloth its arbor rises in guide slots at each side of machine.
The one check of each slot is made part of the side frame, the other cheek being
made with a hinge at the bottom, and capable of being secured at the top with a clasp,
hinged to the fixed cheek.
When the cloth roller is filled; the clasp is unfastened permitting the moveable
cheek to fall down and rest upon the floor or upon a carriage; the cloth roller being
then rolled down the incline formed by said moveable cheek, and deposited where
required.
DESCRIPTION OF DRAWINGS.
Like numbers indicate like parts in all figures.
Fig. 1. (Sheet No. 1.) is a side elevation, and Fig. 2. (Sheet No. 2.) a plan-showing
the said rolling machine, suitably attached to, the cropping machine.
Fig. 3. (Sheet No. 3.) shows a side elevation of rolling machine as used when self-
contained, and not attached to the cropping machine.
1. is the roller used in connection with the uptake motion for taking the cloth off
the cranning machine delivery collars') })

page_text: 3. 3. are the projecting pins.
4. is a toothed wheel-commonly called the "friction wheel "-driven by the
intermediate wheels 5. and 6. from the cropping machine.
7. is the friction plate and 8. the hand wheel with screwed nut working upon the
screw 9., formed upon the arbor 10. passing through roller 1.
The arrangement works in the following manner :-
The wheel 4. revolves freely upon the arbor 10. when driven by wheel 5.
By screwing the nut S. upon 9. the plate 7. may be pressed against the wheel 4.,
because said wheel is kept from moving laterally by the shoulder 11. formed upon the
arbor.
By this means the roller 1. may be driven at the same number of revolutions as the
wheel 4.; or should there be a resistance applied to the roller due to the tension of
the cloth, then the wheel 4. could slide upon the friction plate 7.
By thus adjusting the pressure of the friction plate 7. upon the wheel 4., the
roller 1. may be made to revolve at any speed less than that of wheel 4. when cloth is
being drawn from cropping machine.
12. is the measuring apparatus, 13. being the screw and 14. the screw wheel, while
15. is the index or pointer; the whole combination being similar to that commonly
used in cloth measuring machines.
16. is the roller upon which the cloth taken off cropping machine is rolled.
This roller when empty occupies the position shown at 17. and gradually rises up
the guide slots 18., as it gets cloth rolled upon it.
19. 19. are the fixed, and 20. 20. the moveable cheeks, hinged at 21. 21. to the side
frames, and held in position shown; by hinged clasps 22. 22. on fixed cheeks 19. 19.
Although I have shown the rolling machine attached to the cropping machine as in
Figs. 1. and 2. yet I may make it selfcontained as shown in Fig. 3. in which case the
side frames will be made of the form shown, and will be provided with tension
rails 23. 23. 23. for giving the requisite tension to the cloth; which is fed in from the
side A.
The wheel 5. may in this instance be driven by means of belts and pulleys, working
directly upon its arbor.
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
First: The combination of a rolling machine, with a cropping machine for the
purpose of winding the cloth upon a roller, substantially as herein set forth.
Second-The selfcontained rolling machine with tension rails, substantially as
described.
