IMPROVEMENTS IN CARDING ENGINES
Year: 1862

page_text: LETTERS PATENT to William Clissold, of Dudbridge Works, near Stroud,
in the County of Gloucester, Machine Manufacturer, for the Invention
of "IMPROVEMENTS IN CARDING ENGINES
"
Sealed the 19th September 1862, and dated the 25th March 1862.
PROVISIONAL SPECIFICATION left by the said William Clissold at the
Office of the Commissioners of Patents, with his Petition, on the 25th
March 1862.
I, WILLIAM CLISSOLD, of Dudbridge Works, near Stroud, in the County of
Gloucester, Machine Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN CARDING ENGINES," to be as follows:-
The object of this Invention is to facilitate the adjustment of the bearing of
the strippers and workers of carding engines.
Hitherto they have generally been adjusted laterally by means of clamping
screw tapped into projections on the side frames of the engines, or screws
coupled to the bearings have been held fast by binding nuts to lugs on the
frames, the screws in each instance acting in a line with the adjustable motion
of the bearings. It is now proposed to slot the lower end of the bearings in
order that they may receive a screw (in the direction of their length) for
effecting the vertical adjustment, and above the slot to chamfer the sides of
each bearing, and prepare them to receive a pair of wedge-shaped clamps.

page_text: Tapped into the clamps which slide over guides on the inner side of the
frame are screws that project inwards from the outer face of the frame; by the
slackening therefore of one wedge and the tightening up of the other, a lateral
adjustment will be given to the bearings; this application of the wedge clamps
admits of obvious modification. The screw employed for giving the vertical
adjustment is provided with two collars which embrace the lower end of the
slotted bearing, and it is tapped into the side of a clamping guide pin, over
which the bearing is free to slide while being vertically adjusted. This
clamping guide pin is held fast to the frame of the engine by a fulcrum screw
which must be slackened before any adjustment of the bearing can take place.
When the adjustment has been effected this fulcrum screw is again tightened
and the bearing is firmly held in position.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clissold in the Great Seal Patent Office on the
25th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLISSOLD, of Dudbridge Works, near Stroud, in the County of Gloucester,
Machine Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Clissold, Her special license that I, the said
William Clissold, my executors, administrators, and assigns, or such others
as I, the said William Clissold, my 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
"IMPROVEMENTS IN CARDING ENGINES," upon the condition (amongst others)
that I, the said William Clissold, by an instrument in writing under my
hand and seal, 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

page_text: NOW KNOW YE, that I, the said William Clissold, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
The object of this Invention is to facilitate the adjustment of the bearings of
the strippers and workers of carding engines. .
Hitherto they have generally been adjusted Interally by means of clamping.
screws tapped into projections on the side frames of the engine or screws
coupled to the bearings, have been held fast by binding nuts to lugs on the
frames, the screws in each instance acting in a line with the adjustable motion
of the bearings.
As an improvement on these modes of adjustment I employ the arrange-
ment shewn in the accompanying Drawing, in which Fig. 1 is a side view of a
bearing with the novel means of adjusting it, as seen from inside one of the
side frames of a carding engine; Fig. 2 is an edge view of the same; and
Fig. 3 is a sectional plan view.
In these Figures A, A, is a portion of one of the side frame of the carding
engine, and B is a worker or stripper roller carried by a pair of arms, one of
which is shewn at C. These arms are formed as is usual with the bearings at
their outer ends to receive the journals of their respective workers or stripper
rollers, and are slotted at their lower ends for the purpose to be presently
explained. Above the slot the sides of the arms are chamfered to allow of
their being embraced by a pair of wedge-shaped clamps D, D. These clamps
are carried by screws d, d, which project inwards from the outer face of the
frame A, and they are confined between guides a, a, (over which they slide)
cast on or otherwise attached to the inner side of the frame. From this
explanation of the construction of the parts for holding the arms C in position
it will be readily understood that by simply slackening one clamping wedge D
and tightening up the other, the lateral adjustment of the arm and the bearing
forming part therewith will be effected. This application of the wedge clamps
I would remark admits of obvious modification, as will be manifest to any
practical mechanic, but I prefer the arrangement shewn, both for its simplicity
of construction and efficiency of action. For obtaining the vertical or more
properly speaking the radial adjustment of the workers or stripper, I provide
a radial screw E, fitted with two collars, which embrace the lower end of the
slotted bearing C. This screw I tap into the side of a clamping pin F, which
projects through the slot in the arm C, and is secured to the frame A by a
fulcrum screw f. Before any adjustment of the stripper bearing can take place

page_text: the clamping guide pin F which serves to hold the arm C fast to the frame of
the engine must be slackened by unscrewing the fulcrum screw f; then by
turning the screw E (which is tapped into the guide pin F) either to the
right or left the required adjustment of the worker or stripper either to or
from the carding cylinder will be readily effected. In like manner the slack-
ness of the clamping guide pin F allows of the wedge clamps being operated
with facility by their screws d,d, to effect the lateral adjustment of the
roller. The fulcrum screw being now again tightened the bearing will be
firmly held in position.
Having now set forth the nature of my Invention of improvements in
carding engines, and explained the manner of carrying the same into effect,
I wish it to be understood that under the above in part recited Letters Patent
I claim adjusting the bearings of strippers and workers in the manner above
described.
In witness whereof, I, the said William Clissold, have hereunto set my 1
band and seal, the Twenty-fourth day of September, in the year of
our Lord One thousand eight hundred and sixty-two.
WILLIAM CLISSOLD.
