Year: 1873

page_text: LETTERS PATENT to John Thornton, Joseph Thornton, and Albert
Thornton (trading under the Firm of John Thornton and Sons), of
Cleckheaton, in the County of York, Machine Makers, for the
Invention of "IMPROVEMENTS IN CARDING ENGINES."
Invention of "IMPROVEMENTS IN CARDING ENGINES."
PROVISIONAL SPECIFICATION left by the said John Thornton, Josephi
Thornton, and Albert Thornton at the Office of the Commissioners
of Patents, with their Petition, on the 21st November 1873.
We, JOHN THORNTON, JOSEPH THORNTON, and ALBERT THORNTON
(trading under the Firm of John Thornton and Sons), of Cleckheaton, in
the County of York, Machine Makers, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN CARDING ENGINES," to be as
follows:
"
This Invention relates to the "fixings or supports or standards
which carry the "worker" and the "stripper" of carding engines. The
object is to so construct the said supports or standards that the same
may be more readily adjusted or moved, so as to secure true position for

page_text: the said working and stripping rollers, that the bearings or standards so
constructed shall be stronger and constructed at less cost.
We secure to the "bend" by bolts two bosses or projections having a
hole therein in the direction of their length, which is tapped or screwed,
and within which the "pillar" of the "fixing" is received, its lower
portion being chased or screwed with a thread corresponding to that
within the bosses. The "pillar" of the "fixing" is provided with one or
more holes bored at right angles to its length, so as to receive the end of
a round key for adjusting the height of the necks carried on the top of
the pillars. A lock nut secures the pillars firmly in position when
adjusted vertically. Lateral or sideway adjustment is secured by means
of the ordinary side screws.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Thornton, Joseph Thornton, and Albert
Thornton in the Great Seal Patent Office on the 21st May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
THORNTON, JOSEPH THORNTON, and ALBERT THORNTON (trading under
the Firm of John Thornton and Sons), of Clecklicaton, in the County of
York, Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said John Thornton, Joseph
Thornton, and Albert Thornton, Her special licence that we, the said
John Thornton, Joseph Thornton, and Albert Thornton, our executors,
administrators, and assigns, or such others as we, the said Jolin
Thornton, Joseph Thornton, and Albert Thornton, our executors, admini-
strators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN CARDING
ENGINES, upon the condition (amongst others) that we, the said John
"

page_text: Thornton, Joseph Thornton, and Albert Thornton, our executors or
administrators, by an instrument in writing under our, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner 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.
NOW KNOW YE, that we, the said John Thornton, Joseph Thornton,
and Albert Thornton, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement (that is to
say):-
"
This Invention relates to the "fixings or supports or standards
which carry the "worker" and the "stripper" of carding engines. The
object is to so construct the said supports or standards that the same
may be more readily adjusted or moved, so as to secure true position for
the said working and stripping rollers, that the bearings or standards so.
constructed shall be stronger and constructed at less cost.
.We
Te secure to the "bend" by bolts two bosses or projections having a
hole therein in the direction of their length, which is tapped or screwed,
and within which the pillar of the "fixing" is received, its lower portion
being chased or screwed with a thread corresponding to that within the
bosses. The pillar of the "fixing" is provided with one or more holed
bored at right angles to its length, so as to receive the end of a round
key for adjusting the height of the necks carried on the top of the
pillars. A lock nut secures the pillars firmly in position when adjusted
vertically. Lateral or sideway adjustment is secured by means of the
ordinary side screws.
Such being the nature and object of the said Invention, we will now
proceed to describe the same in detail, and in order that the same may
be fully understood, we have hereunto annexed a Sheet of Drawings
illustrative thereof, and have marked the same with letters of
reference, in which Fig. 1 is an end view of a cylinder of a carding
engine, shewing the workers and strippers carried on "fixings," supports,
or standards constructed according to our make; Fig. 2 is a front view
of a fixing detached, and drawn about full size; Fig. 3 is a side elevation
of Fig. 2, partly in section; Fig. 4 is a plan of Fig. 2.

page_text: DESCRIPTION OF THE DRAWINGS.
We secure to the "bend." A the worker and stripper rollers A', A²,
by bolts two bosses or projections. B, C, having a hole therein in the
direction of their length, which is tapped or screwed, and within which the
pillar D (which is of wrought iron) of the "fixing" is received, its lower
portion being chased or screwed, as shewn at E, with a thread
corresponding to that within the bosses. The said pillars D of the
'fixing" are provided with one or more holes F bored at right angles
to their length, so as to receive the end of a round key for turning the
pillars, and so adjusting the height of the necks G carried on the top of
the pillars. A lock nut H secures the pillars firmly in position when
adjusted vertically. Lateral or sideway adjustment is secured by means
of the ordinary side screws J.

Having thus fully described the nature and particulars of this our
said Invention, together with the manner in which the same is to be or
may be performed or carried into practical effect, we would have it
understood that we claim, the application and use of the bosses B and C
for carrying the fixings of the workers and strippers of carding engines,
constructed substantially as here described and shewn in the Drawings.
In witness whereof, I, the said Joseph Thornton, for and on behalf
of myself and the said John Thornton and Albert Thornton, have
hereunto set my hand and seal, this Twentieth day of May, in
the year of our Lord One thousand eight hundred and seventy-
four.
