IMPROVEMENTS IN THE CONSTRUCTION OF CARDING ENGINES
Year: 1875

page_text: LETTERS PATENT to John Percival Haslam, of Bolton, in the County
of Lancaster, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF CARDING ENGINES."
Sealed the 26th October 1875, and dated the 28th August 1875.
PROVISIONAL SPECIFICATION left by the said John Percival Haslam
at the Office of the Commissioners of Patents, with his Petition,
on the 28th August 1875.
I, JOHN PERCIVAL HASLAM, of Bolton, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF CARDING ENGINES," to be as follows:-
" for
This Invention relates to that class of carding engines which are
provided with what are well known as "Wellman's strippers
stripping the flat cards, and is designed to cleanse the stripper itself
from dirt thus accumulated.
The principal objection to the "Wellman stripper" consists in the
fact that after stripping one flat the stripper has itself to be cleansed by
the next flat before stripping it, by which proceeding the points of the

page_text: cards are blunted. To obviate this I place across the machine and
immediately behind the stripper a bar covered with wire cards, and so
disposed that directly the stripper advances to strip the flat it is itself
cleansed by this bar, and there is no necessity for the stripper to touch
the teeth of the flat in going forward. This bar is attached at each end
to the counterbalanced levers which carry the stripping apparatus, and
consequently it is taken round with the stripper as it visits in turn each
flat.
.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Percival Haslam in the Great Seal Patent
Office on the 28th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PERCIVAL HASLAM, of Bolton, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors; give and grant unto me, the said John Percival Haslam, Her
special license, that I, the said John Percival Haslam, my executors,
administrators, and assigns, or such others as I, the said John Percival
Haslam, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, excrcise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN THE CONSTRUCTION OF CARDING ENGINES,' upon
the condition (amongst others) that I, the said John Percival Haslam,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
hanner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
"

page_text: NOW KNOW YE, that I, the said John Percival Haslam, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Drawings:-
This Invention relates to that class of carding engines which are
provided with what are well known as "Wellman's strippers" for
stripping the flat cards, and is designed to cleanse the stripper itself
from dirt thus accumulated.
The principal objection to the "Wellman stripper" consists in the
fact that after stripping one flat the stripper has itself to be cleansed by
the next flat before stripping it, by which proceeding the points of the
cards are blunted. To obviate this I place across the machine and
immediately above the stripper a bar covered with wire cards, and so
disposed that directly the stripper advances to strip a flat it is itself
cleansed by this bar, and there is no necessity for the stripper to touch
the teeth of the flat in going forward. This bar is attached at each end
to the counterbalanced levers which carry the stripping apparatus, and
consequently it is taken round with the stripper as it visits in turn each
flat.
Such being the nature and object of my said Invention I will now
proceed to describe 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 hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with letters
of reference corresponding with those in the following explanation
thereof :-
The annexed Drawing represents a side elevation (shown partly in
section) of so much of a carding engine fitted with the "Wellman
stripper" as is necessary to illustrate my Invention.
a, a, are the top flats, one of which a* is shown as raised to be
stripped by the stripper b, b. Above the stripper b, b, and attached at
each end to the counterbalance levers c, c, which carry the stripping
apparatus is a bar d, d, covered with wire cards, and so arranged that as
the stripper b, b, advances to strip the flat a* it is itself cleaned by
passing under this bar d, d, and hence there is no necessity for the
stripper b, b, to touch the points of the cards of the flat a* in going
forward. The cards or wires of the bar d, d, are inclined or bent in the

page_text: same direction as those of the flats, and consequently they clean the
stripper in precisely the same manner as the flats ordinarly do, whilst
the wear of the points of the cards of the latter is greatly reduced.
"
Instead of using the ordinary flat springs to press down the "flat'
into its place after stripping, I employ two coiled springs e, e, one
acting at each end of the flat, and carried by the counterbalance
lever c, c.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be performed
or carried into practical effect, I wish it to be understood that I claim 1
as my Invention, the application to carding engines fitted with the
"Wellman stripper" of a cleaning bar, substantially in the manner
and for the purpose herein-before more particularly set forth and
described.
In witness whereof, I, the said John Percival Haslam, have here- 1
unto set my hand and seal, this Twenty-fifth day of February, in
the year of our Lord One thousand eight hundred and seventy-
six.
