PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Grinding the Cards of Carding
Engines.
We, GEORGE ALEXANDER KENNEDY, of the Firm of Horsfall & Bickham, Card
Makers, and WILLIAM SENIOR, Mechanic, both of Bridgewater Works, Pendleton,
in the County of Lancaster, do hereby declare the nature of this invention to be
as follows:-
This invention relates to that kind of apparatus for grinding the cards of carding
engines known as the "Horsfall Grinder," the object being to apply thereto a
simple and noiseless differential motion for driving the screw from the tube.
According to our invention we provide a circular casing to be placed on the end
of the grinder, and a suitable bracket to prevent it from revolving. Upon the end
of the tube which projects part way into the casing we fix a suitable bracket, arm
or disc carrying bearings supporting a short shaft on which is fitted a worm which
is rotated as the tube revolves by a suitable beveled worm wheel in gear with an
internal spiral thread formed or fitted inside the cylindrical part of the fixed casing
of the "motion." The worm thus rotated by this beveled worm wheel is in gear
with a worm wheel on the screw which it thus drives at the desired speed.
This motion besides being simple, and compact is almost noiseless and thus the
setting of the grinder is greatly facilitated.
In some cases the fixed spiral thread may be formed on an internal boss on one
of the ends of the fixed casing or the thread may be formed on the face of one end
of the casing.

Engines.
We, GEORGE ALEXANDER KENNEDY, of the Firm of Horsfall & Bickham, Card
Makers, and WILLIAM SENIOR, Mechanic, both of Bridgewater Works, Pendleton,
in the County of Lancaster, 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 that kind of apparatus for grinding the cards of carding
engines known as the "Horsfall Grinder," the object being to apply thereto a
simple and noiseless differential motion for driving the screw from the tube.

page_text: The invention will be readily understood from the following description on
reference to the drawings hereunto annexed.
Fig. 1 is an elevation partly in section of so much of a "Horsfall Grinder" as is
necessary to illustrate our invention; and
being a detached face view of the worm
Fig. 2 is a section through A A on Fig. 1.
Fig. 3 is a plan of the casing a and bracket a*.
Fig. 4 illustrates a modification, Fig. 4
wheel, shown in side elevation at Fig. 4.
According to our invention we provide a circular casing a to be placed on the end of
the grinder, and a suitable bracket ax to prevent it from revolving when the grinder
is fitted in the bracket axx fixed on the frame as usual. Upon the end of the
tube b which projects part way into the casing a we fix a suitable bracket b¹ or its
equivalent carrying bearings 62 supporting a short shaft c on which is fitted or
formed a worm c¹ which is rotated as the tube b revolves by a suitable beveled
worm wheel c² in gear with an internal spiral thread a² formed or fitted inside the
cylindrical part of the fixed casing a of the apparatus. The worm c¹ thus rotated
by this beveled worm wheel is in gear with a worm wheel d¹ on the screw d which
it thus drives at the desired speed.
This motion or apparatus besides being simple, and compact is almost noiseless,
and thus the setting of the grinder is greatly facilitated.
In some cases the fixed spiral thread a² may be formed on the face of one end of
the casing a as seen at Fig. 4, the worm wheel c² being in the form shewn also at
Fig. detached.
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 combination in a suitable casing prevented from revolving by a bracket to
be fixed to the frame of the carding engine (or otherwise) of a worm wheel fixed
on the screw driven by a worm in the casing, the said worm being carried by
brackets fixed on the tube and driven by a wheel from a fixed worm or thread in
the casing, substantially as herein before described.
