I, THOMAS BISPHAM KAY of Arcade Chambers St. Mary's Gate Manchester in the
County of Lancaster Mechanical 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 of "Improvements in Carding Engines as described in
Specification of Letters Patent granted to ine the said Thomas Bispham Kay on the
25th July 1884 No. 10565.
According to the Invention therein specified the cam surfaces and toothed wheels
are shown and described as rotating upon studs fixed upon the radial supporting
brackets upon each side of the Carding Engine and carrying the spring platforms
for steadying the flats against the grinding surfaces and as being actuated and
controled by the flats themselves when travelling along and during the operation of
grinding. The slides and grinding brackets are also shown and described as having
their faces plain and perforated for the affixing bolts only. With this arrangement I
have found a certain degree of unsteadiness of motion and consequent inaccuracy of
grinding to be caused by the varying tension of the chain of flats. Now according
to my present Invention I remove the fixed studs and substitute a shaft carried in
sockets across the Carding Engine upon which the aforesaid cam surfaces and toothed
wheels are fixed and the spring platforms rest and I drive the same by chain or worm
and wheel or by both, so that the aforesaid toothed wheels bear upon the flat snugs
and actuate and control the motion of the flats with respect to the cam surfaces so as
to ensure greater uniformity of motion and accuracy in the grinding of the flats. I
also perforate the faces of the slides and grinding brackets so as to permit the afore-
said shaft to project through the same.

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-

of Letters Patent granted to me the said Thomas Bispham Kay on the 25th July 1884
No. 10565, & on 4th December 1885, No. 14876.
According to the Inventions therein specified the cam surfaces and toothed wheels
are shown and described as rotating upon studs fixed upon the radial supporting
brackets upon each side of the Carding Engine, and carrying the spring platforms

Such being the nature and object of my 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 of reference corresponding with those in the following explanation.
sides of the Carding Engine are alike so far as this my present Invention is
concerned I shall describe that on one side only.
As both
Figs. I II III & IV represent partial sectional and side views respectively of
my improved arrangement.
In Figs. I and II. R is the radial supporting bracket, S is the slide therein
carrying the bowl O resting upon the cam surfaces G attached to a boss rotating in
the socket V bolted upon R. To G is affixed the toothed wheel F for actuating the
flat C so that they rotate together. Through the boss on G is passed the shaft K to
which it is keyed or screwed and which-supports the spring platform W for steadying

page_text: the flat against the grinding gauge J. This shaft K is carried across the Carding
Engine thus connecting the two sets of mechanism one upon each side so that they
act together and is driven by chain gearing or by worm and wheel or otherwise, the
extremity of the shaft K projecting for this purpose through and beyond the slide S
and the grinding roller bracket M. By thus connecting the two sets of mechanism one
upon each side of the Carding Engine I can better regulate the motion of the flat
when grinding and its position with reference to the grinding roller.
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 what I claim is,
1. Connecting the two sets of mechanism one upon each side by a shaft carried
across the Carding Engine so that they act together.
2. Perforating the slide and grinding roller bracket so that the connecting shaft
may project through the same.
3. The general arrangement of mechanism for regulating and controling the flats
when grinding or any mere imitation of the above described arrangement of parts
respectively when used substautially in the same manner and for the same purposes
as hereinbefore described set forth and illustrated.
