AN IMPROVED SELF-ACTING COMBINATION OF MACHINERY FOR THE GRINDING OF CARDING ENGINE ROLLERS
Year: 1857

page_text: LETTERS PATENT to Thomas Sidebottom Adshead, of North End, near
Stalybridge, in the County of Chester, Cotton Spinner, and Abraham
Holden, of the same Place, Cotton Carder, for the Invention of "AN
IMPROVED SELF-ACTING COMBINATION OF MACHINERY FOR THE GRINDING OF
CARDING ENGINE ROLLERS."
Sealed the 18th May 1858, and dated the 5th December 1857.
PROVISIONAL SPECIFICATION left by the said Thomas Sidebottom
Adshead and Abraham Holden at the Office of the Commissioners of
Patents, with their Petition, on the 5th December 1857.
We, THOMAS SIDEBOTTOM ADSHEAD, of North End, near Stalybridge, in the.
County of Chester, Cotton Spinner, and ABRAHAM HOLDEN, of the same
Place, Cotton Carder, do hereby declare the nature of the said Invention.
for "AN IMPROVED SELF-ACTING COMBINATION OF MACHINERY FOR THE GRINDING.
OF CARDING ENGINE ROLLERS," to be as follows:-
Our Invention consists of an improved self-acting combination of machinery,
for the grinding of carding engine rollers. In performing our Invention a
table made of iron or any other suitable material, and covered with emery or
other grinding material, is made to traverse to and fro, and the rollers to be
ground are placed in the ordinary adjusting brackets. The brackets and
rollers have a traverse motion imparted to them in the contrary direction to

page_text: that of the table. By this means the wire on the rollers is ground to a much
better point and in less time than heretofore. The rollers when taken off the
table are quite ready for carding purposes, thus doing away with the necessity
of being finished by hand.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Sidebottom Adshead and Abraham Holden in the
Great Seal Patent Office on the 5th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
SIDEBOTTOM ADSHEAD, of North End, near Stalybridge, in the County of
Chester, Cotton Spinner, and ABRAHAM HOLDEN, of the same Place, Cotton
Carder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of December; in the year of our Lord
One thousand eight hundred and fifty-seven, in, the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Sidebottom Adshead and Abraham Holden, Her special liceuco
that we, the said Thomas Sidebottom Adshead and Abraham Holden, our
exccutors, administrators, and assigns, or such others as we, the said Thomas
Sidebottom Adshead and Abraham Holden, our executors, administrators, 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
"AN IMPROVED SELF-ACTING COMBINATION OF MACHINERY FOR THE GRINDING OP
CARDING ENGINE ROLLERS," upon the condition (amongst others) that we, the
said Thomas Sidebottom Adshead and Abraham Holden, our executors or
administrators, by an instrument in writing under our or their, or one of our
or 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 tho samo 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 Thomas Sidebottom Adshead and
Abraham Holden, 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):-

page_text: The nature of our Invention consists of an improved self-acting combination
of machinery for the grinding of carding engine rollers.
And in order that our Invention may be fully understood and readily
carried into practical operation, we will proceed to describe the means pursued
by us, reference being had to the accompanying Sheet of Drawings and to the
figures and letters marked thereon.
$
Fig. 1 is an end view of our improved machinery; Fig. 2 is a side view of
the same; and Fig. 3 a plan, with the upper portion removed in order that
the under parts may be better shewn. a is the main shaft, to which motion
is communicated by a strap passing over the driving pulley a¹; to this shaft
are also fixed the pulleys a³ and as for driving the rollers to be ground, and
the pinion at which gears in the wheel fixed to the shaft 6; the spur
pinion 62 and bevel pinion 63 are also fixed to this shaft; the former gears
into the wheel c' on the shaft c, and the latter in the bevel wheel & on the
shaft d. To the shaft c is fixed the excentric c³, which imparts a vibrating
motion to the lever et fixed to the shaft e, to which are also fixed the wheels
gearing into the racks f¹ attached to the under side of the table f. The
upper surface of this table is covered with emery or other grinding material.
The table. is supported in brackets g³, g³, seen best in Fig. 3, and slides
laterally in these brackets, to the extent of about three inches, or more or less.
To the shaft d is fixed the excentric &, which imparts a vibrating motion to
the lever g fixed to the shaft g, and on this shaft are fixed the two pinions g³,
gearing into the racks
attached to the under side of the frame h, which is.
supported in the slides fixed to the top of the framing. By this means the
frame h is moved to and fro in a direction at right angles to that of the
table f. To each end of the frame h are attached the adjustable brackets h³,
in which the rollers to be ground are supported; to the axles of these rollers
are fixed pulleys, which are turned round by straps passing under the pulleys
a² and a³, as clearly shewn in Figs. 1. and 2. By thus imparting a rotary and
longitudinal motion to the rollers to be ground, and a lateral motion to emery
table, the wire on the roller is ground to a much better point and in less
time than by the grinding machinery hitherto employed, and the rollers when
taken out of the machine are quite ready for being used on the carding
engine, thus dispensing with the necessity of being finished by hand, as is
usually practised.
The machine shewn in the Drawing is calculated to grind four small rollers
or two large ones, or one large and two small; but the size of the machine
may be varied at pleasure, so as to grind more or less rollers at once.
We wish to remark that our improved machinery for grinding rollers may

page_text: be modified by imparting both the lateral and longitudinal motions to the
frame in which the rollers revolve and are supported while the grinding
surface remains stationary, or the rollers may revolve in a stationary frame
while the lateral and longitudinal motions are imparted to the grinding
surface.
Having thus stated the nature of our Invention, and described the manner
of carrying the same into operation, we wish it to be understood that we do
not limit ourselves to the details set forth, as the same may be varied
without departing from the peculiar character thereof; but what we do claim
is the combination of machinery herein-before described, and shewn in the
accompanying Drawing, or any other combination of machinery whereby a
longitudinal in addition to the rotary motion is given to the rollers to be
ground, and a lateral motion to the emery table or other grinding surface, or
in applying the longitudinal and lateral motions to the frame supporting the
rollers while the grinding surface remains stationary, or in applying the
longitudinal and lateral motions to the grinding surface while the rollers to be
ground revolve in stationary' bearings.
In witness whereof, we, the said Thomas Sidebottom Adshead and
Abraham Holden, have hereunto set our hands and seals, this Third
day of June, One thousand eight hundred and fifty-eight.
Witness,
H. B. BARLOW,
THOMAS SIDEBOTTOM ADSHEAD. (L.S.)
