Improvements in Apparatus for Speeding the Cylinders and Doffer
of Carding Engines when Grinding the Cards thereon, and in
Appliances for Grinding Cards Generally.
I EDMUND TWEEDALE of Globe Works Accrington in the County of Lancaster
Manager, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improved construction, combination and arrangement of
pulleys and gear for purpose of reducing the speed of the cylinder and doffer of
carding engines when grinding the cards thereon-and to an improved grinding wheel
or disc applicable for grinding the cards on the cylinder and doffer and for grinding
card flats or cards generally.
For purpose of speeding the cylinder and doffer when grinding the cards thereon,
I employ on the shaft of the cylinder a loose boss and on the latter is a pulley having
a worm cut or formed in its boss.
The loose boss first referred to has at one end a plate from which project at opposite
sides, two arms, attached to the side of the engine-and in this plate is a stud carrying
a worm wheel-As the pully and worm revolve, they drive the worm wheel, and on
the boss of the latter is a bevel wheel, gearing with a like wheel on one end of a stud
fixed in the plate referred to-and on the other end of the said stud is a pinion wheel
gearing with (by preferance) an internal tooth wheel fast on the shaft of the cylinder-
By means of the gear described, the surface speed of the cylinder is reduced whilst the
speed of the first driving pulley is utilized for driving the grinding wheel, the grinding
disc, or the grinding appliance.
In the manufacture of discs or wheels for grinding cards I employ discs preferably
of steel the outer edge or circumferance of which is of A form. Near the outer
edge or circumferance I perforate or form holes through the disc-the holes are filled
with emery. The holes may be circular rectangular or of other form and may be
radial or radius to the axis on which the disc or wheel is mounted.

page_text: In some cases I omit or cut away part of the outer diameter of the disc or grinding
wheel so that its action is intermittent or only partial at each revolution, this con-
struction may be preferable for grinding card fillets sheets or flats.
It will seem that the outer edge or circumferance of the disc is steel or metal, whilst
the part of the disc which performs the actual work of grinding or pointing the cards
is is in the main emery. I thus obtain the advantage of emery for grinding, whilst
the outer edge being of metal is not liable to fracture and breakage as are the edges of
discs composed wholly of emery.

of Carding Engines when Grinding the Cards thereon, and in
Appliances for Grinding Cards Generally..
I EDMUND TWEEDALE, of Globe Works, Accrington in the County of Lancaster,
Manager, 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 relates to improved construction, combination, and arrangement of
pulleys, and gear for purpose of reducing the speed of the cylinder, and doffer, of
carding engines, and grinding the cards thereon and to an improved grinding wheel
or disc applicable for grinding the cards on the cylinder, and doffer, and for grinding
card flats, or cards generally. For purpose of speeding the cylinder and doffer when
grinding the cards thercon I employ on the shaft of the cylinder a loose pulley having
a worm cut or formed in its boss, the loose pulley has at one end a plate from which
project at opposite sides two arms attached to the side of the engine and in this plate
is a stud carrying a worm wheel. As the pulley and worm revolve they drive the
worm wheel, and on the boss of the latter is a bevel wheel on one end of a stud fixed
in the plate referred to, and on the other end of the said stud is a pinion wheel gearing
with (by preference) an internal tooth wheel fast on the shaft of the cylinder. By
means of the gear described the surface speed of the cylinder is reduced whilst the
speed of the first driving pulley is utilized for driving the grinding wheel, the grinding
disc, or the grinding appliances.
In the manufacture of discs, or wheels for grinding cards I employ discs preferably
of steel, the outer edge or circumference of which is of V form. Near the outer edge
or circumference I perforate or form holes through the disc, the holes are filled with
emery. The holes may be circular, rectangular or of other form, and may be radial
or radius to the axis on which the disc or wheel is mounted. In some cases I omit or
cut away part of the outer diameter of the disc, or grinding wheel so that its action is
intermittent or only partial at each revolution this construction may be preferable for
grinding card fillets, sheets, or flats. It will be seen that the outer edge, or circum-
ference of the disc is steel, or metal whilst part of the disc which performs the actual
work of grinding, or pointing the cards is in the main emery. I thus obtain the
advantage of emery for grinding, whilst the outer edge being of metal is not liable to
fracture, and breakage, as are the edges of discs composed wholly of emery.
Such being the nature and object of the said invention the following is a complete
description of same reference being had to the accompanying drawings forming a part
of this specification in which :-
Fig. 1. is a front elevation of improved apparatus for speeding the cylinder, and
deffer.
Fig. 2. is a sectional plan of Fig. 1.

page_text: Figs. 3 and 4 are elevation, and section of improved grinding wheel or disc for
grinding, and pointing the cards Fig. 3 shewing one part of disc before being coated
with emery
At 1 is the shaft of the cylinder, and on the latter is a loose boss 2, upon which is
the pulley 3, having a worm 4, cut, or formed in its boss. The loose boss 2, has at onc
end a plate 5, from which projects at opposite sides two arms 6. 7. which are attached
to the side 8, of the engine, and bolted on the plate 5, is a bracket plate 5^, (see Fig. 1)
carrying the two ends of the stud 9. on which is a worm wheel 10.
As the pulley 3, and worm 4, revolve they drive the worm wheel 10, and on the
boss of the latter is a bevel wheel 11, gearing with a like wheel 12, on one end of a
stud 13, fixed in the plate 5, on the other end of stud 13, is a pinion wheel 14, gearing
with the internal toothed wheel 15 fast on the shaft 1, of the cylinder.
By means of the gear described the surface speed of the cylinder is reduced whilst
the speed of the first driving pulley 3, is utilized for driving the grinding wheel, the
grinding disc, or the grinding appliances.
In the manufacture of discs, or wheels for grinding cards I employ discs 16,
preferably of steel, mounted on boss or axis 19. spaced by washers 20 and secured by
screw collar 21 the outer edge or circumference of each disc is of A form, near the
outer edge, or circumference I perforate or form holes 17 through the disc, the holes
are filled with emery, and its outer surface may be coated with emery, as at 18. The
holes may he circular, rectangular, or of other form, and may he radial, or radius, to
the axis on which the disc or wheel is mounted. In some cases I omit or cut away
part of the outer diameter of the disc, or grinding wheel, so that its action is inter-
mittent, or only partial at each revolution, this construction may be preferable for
grinding card fillets, sheets, or flats. It will be seen that the outer edge, or circum-
ference of the disc is of steel, or metal whilst part of the disc which performs in the
main the actual work of grinding, or pointing the cards is composed mainly of emery.
I thus obtain the advantage of emery for grinding, whilst the outer edge being of
metal is not liable to fracture, and breakage, as are the edges of discs composed wholly
of emery..
Having now particularly described and ascertained the nature and particulars of the
said invention and in what manner the same is to be employed I declare that what
I claim is
1. The general construction, combination, and arrangement of parts constituting
the improved apparatus for purpose aforesaid, and as herein fully described and
substantially as illustrated by the drawings annexed.
2. The improved grinding disc or wheel comprising the steel, or metal perforated
plate combined with emery for purpose, and substantially as illustrated by annexed
drawings.
