IMPROVEMENTS IN CARDING ENGINES
Year: 1885

page_text: I THOMAS BISPHAM KAY of 3 Arcade Chambers St Mary's Gate Manchester in
the County of Lancaster Engineer do hereby declare the nature of my invention
for "IMPROVEMENTS IN CARDING ENGINES," to be as follows:-
My Invention relates to certain modifications of and improvements in the
mechanical details for setting and grinding the top cards or flats of carding engines
described in Specon of Letters Patent granted to me the said Thomas Bispham
Kay on the 25th day of July 1884 No. 10565 for "Improvements in Carding
Engines."
According to the Invention therein specified the cam surfaces and the bowls are
shown and described as being carried between the radial brackets and the flat ends.
The flats are also shown and described when grinding as being steadied by elastic
rings attached to the toothed wheels and as sliding over the shoulders affixed to
the adjustable radial supporting brackets. The grinding roller brackets are also
shown and described as sliding in a radial direction upon the adjustable radial
supporting brackets. The flats are also shown and described as actuating the
toothed wheels carrying the cam surfaces by gearing therewith. The toothed
wheels and cam surfaces are also shown and described as rotating synchronously.
The parallel guides are also shown and described as being formed separate from
and afterwards affixed to the radial supporting brackets and the cone setting
screws as formed with threads of one pitch only.
Now according to my present Invention I bring the cam surfaces and the bowls
outside the radial brackets. I also employ spring platforms for steadying the
toothed wheels and the flats when grinding. I also make each toothed wheel so
as to clip the flat snugs by dividing the same and connecting the parts by a spring.
I also make the grinding roller brackets to oscillate when acted upon by the cam
surfaces rotating on the fixed centres. I also arrange the grinding roller brackets.
and the cam brackets to oscillate from the same centres. I also actuate the cams
by gearing them with the flat driving discs. I also gear the toothed wheels with
the cam surfaces so that the number of rotations of the latter may be a multiple
of those of the former. I also form the fixed radial supporting brackets and each
parallel guide carried thereby in one piece and I also form each cone setting screw
with two sets of threads of different pitch tapped into the fixed brackets and the
cone respectively.
By this arrangement I obtain a more convenient mechanism and greater accuracy
in the grinding and setting of the flats.

be performed, to be particularly described and ascertained in and by the following
statement:-
My Invention relates to certain modifications of and improvements in the
mechanical details for setting and grinding the top cards or flats of carding engines
described in Specon of Letters Patent granted to me the said Thomas Bispham
Kay on the 15th day of July 1884 No. 10565 for "Improvements in Carding

According to the Invention therein specified the cam surfaces and the bowls are
shown and described as being carried between the radial brackets and the flat ends.
The flats are also shown and described when grinding as being steadied by elastic

the adjustable radial supporting brackets. The grinding roller brackets are also

Now according to my present Invention I bring the cam surfaces and the bowls
outside the radial brackets. I also employ spring platforms for steadying the
toothed wheels and the flats when grinding. I also make each toothed wheel so
as to clip the flat snug by dividing the same and connecting the parts by a spring.
I also make the grinding roller brackets to oscillate when acted upon by the cam
surfaces rotating upon the fixed centres. I also arrange the grinding roller
brackets and the cam brackets to oscillate from the same centre. I also actuate
the cams by gearing them with the flat driving discs. I also gear the toothed
wheels with the cam surfaces so that the number of rotations of the latter may be
a multiple of those of the former. I also form the fixed radial supporting brackets
and each parallel guide carried thereby in one piece, and I also form each cone
setting screw with two sets of threads of different pitch tapped into the fixed
brackets and into the cone respectively.
By this arrangement I obtain a more convenient mechanism and greater accuracy
in the grinding and setting of the flats.
Such being the nature and object of iny said Invention for "Improvements in
Carding Engines" I will now proceed to describe more in detail the manner in
which the same is to be or may be performed or carried into practical effect, and
in order that the same may be clearly understood I have annexed hereto a Sheet
of Drawings illustrative thereof and have marked the same with figures and letters

page_text: of reference corresponding with those in the following explanation, all the Drawings
being about one third the real size. As both sides of the Carding Engine are alike
so far as this my present Invention is concerned I shall describe that on one
side only.
•
Figs. I and II represent partial front and side views of my improved arrangement
of grinding mechanism.
Figs. III and IV represent partial front views of my improved arrangement for
supporting the grinding roller and for actuating the cam surfaces respectively.
Figs. V, VI, VII represent partial sectional and front views of my improved
spring platform for steadying the flats when grinding.
Figs. VIII, IX and X represent front and sectional views of my improved
arrangement of toothed wheel.
Fig. XI represents my improved arrangement of radial bracket and flat guide.
In Figs. I and II, R is the adjustable radial supporting bracket carrying the
chain of travelling flats C; K is a shaft carrying the toothed wheel F and cam
surfaces G and rotating in a socket fixed upon R-O is the bowl rotating on a
stud carried by the adjustable sliding bracket M, and P is the grinding roller
rotating therein. In Fig. III, R is the adjustable radial supporting bracket, K. is
the stud or shaft carrying the toothed wheel and cam surfaces G, O the bowl
rotating on a stud carried by the oscillating lever M³, and M is the adjustable
sliding bracket carried thereupon and P the grinding roller rotating therein. In
Fig. IV, 1, 2, 3 represent a train of wheels connecting the toothed wheel F¹ with
the cam surfaces G. In Figs. V, VI and VII, K is the stud carrying the toothed
wheels and cam surfaces, V is the socket bracket and W the platform with its
springs carried thereupon. In Figs. VIII and IX, F is one part and F' the other
part of my improved tooth wheel and Fig. ✗ shows the two parts together and
connected by their spring J. In Fig. XI, B is the bend, L the radial bracket and
D the parallel guide.
Having thus described my improved mechanism, I shall now proceed to explain
the action of the same. I may here remark that the position. of the cam surfaces
and bowls inside the radial brackets as hitherto arranged sometimes makes it
difficult to keep them clean and ensure their perfect action. This is remedied by
bringing them outside of the said brackets and directly in view of the operating
carder, as shown at O, G in Figs. I and II. Also in some cases it is convenient to
carry the grinding roller P in adjustable sliding sockets M bolted upon the
oscillating levers M¹ and actuated by the cam surfaces G rotating upon the fixed
centre K as shown in Fig. III. In some cases I find it convenient to drive the
cam surfaces by a train of gearing see Fig. IV, and so cause the cam disc to make
two, three or more rotations for each rotation of the toothed wheel,-the cam disc
in such cases requires dividing into one half, one third &c the number of cam
surfaces that there are teeth in the toothed wheel. The better steadying of the
flats when grinding I effect by employing a platform W supported by springs
lying recessed in a socket bracket V carried on the stud K fixed in the radial
bracket R, as shown in Figs. V, VI and VII, by which means I can more
effectually ensure the close sliding contact of the flat with the grinding gauges
until the grinding operation is completed. Again in order to give each flat more
control over its grinding I divide the toothed wheel into two parts fitted to one
another as shown at F, Fl in Figs. VIII and IX and unite them by a spring, an
end of which is attached to each part see Fig. X, so as to cause the alternate teeth
to be pulled in opposite directions and clip the flat snug, thus steadying the
rotation of the cam surfaces actuated thereby. I also simplify the mechanism for
controlling the flats when carding by casting the fixed radial supporting bracket L
and the parallel guide D in one piece as shown in Fig. XI-and by making each
cone setting screw with a double set of threads of different pitch tapped into the
fixed bracket and into the cone respectively, I obtain a resultant movement
steadier and more gradual than by the single threaded screw, tapped into the cone
alone and held by collars in the fixed bracket as heretofore.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare what
I claim is
(1) Arranging the cam, surfaces and bowls so as to be outside the radial
brackets.
(2) Applying spring platforms to steady the flats against the grinding surfaces.
(3) Applying the toothed wheel in parts connected by a spring.
(4) Einploying oscillating levers actuated by can surfaces rotating upon fixed
centres, for carrying the grinding roller.
(5) Interposing gearing between the toothed wheels and the cam surfacos.
(6) Casting the fixed radial supporting brackets and each parallel guide in one
piece.
(7) Forming each cone setting screw with two sets of threads of different pitch
tapped into the fixed brackets and cone respectively.
(8) The general arrangement of mechanism for setting and grinding the flats of
Travelling Flat Carding Engines or any mere imitation of the above described
arrangements of parts respectively when used substantially in the manner and for
the same purposes as hereinbefore described, set forth, and illustrated.
