Year: 1870

page_text: LETTERS PATENT to Edward Lord, of Todmorden, in the County of
York, Machine Maker, for the Invention of "IMPROVEMENTS IN THE
MODES OF REGULATING THE POSITION OF CARD ROLLERS AND OTHER ARTICLES
REQUIRING ACCURATE ADJUSTMENT.”
Sealed the 7th March 1871, and dated the 28th September 1870.
PROVISIONAL SPECIFICATION left by the said Edward Lord at the
Office of the Commissioners of Patents, with his Petition, on the
28th September 1870.
I, EDWARD LORD, of Todmorden, in the County of York, Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MODES OF REGULATING THE POSITION OF CARD ROLLERS AND OTHER
ARTICLES REQUIRING ACCURATE ADJUSTMENT," to be as follows:-
My Invention is chiefly applicable in regulating the position of rollers
working in combination with the main cylinders of carding engines, but

page_text: it may be employed in adjusting the position of the bearings of other
rollers, and for other purposes.
In applying my Invention to the working rollers of carding engines
the roller bearing fits between ribs cast on the outer side of a plate, the
inner part of which fits between ribs cast on the bend of the carding
engine, the bearing, the plate, and the bend being secured together by a
bolt and nut. The roller is adjusted by a right and left handed regu-
lating screw, one part of which is screwed into a projection from the
bearing and the other part is screwed into the plate, consequently, when
the regulating screw is turned partly round the bearing is moved to and
fro in the plate.
My Invention may be modified by making the regulating screw with
a coarse and fine thread.
In applying my Invention to adjust the position of other bearings
and for other purposes the regulating screws must pass through a fixed
part of the machine as well as through the bearing or other article to
be adjusted.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Lord in the Great Seal Patent Office on
the 27th March 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LORD, of Todmorden, in the County of York, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of September, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Lord, Her special licence
that I, the said Edward Lord, my executors, administrators, and assigns,
or such others as I, the said Edward Lord, 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,

page_text: and Isle of Man, an Invention for "IMPROVEMENTS IN THE MODES OF
REGULATING THE POSITION OF CARD ROLLERS AND OTHER ARTICLES REQUIRING
ACCURATE ADJUSTMENT," upon the condition (amongst others) that I, the
said Edward Lord, 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 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 I, the said Edward Lord, 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 (that is to say) :-
:-
My Invention is chiefly applicable in regulating the position of rollers
working in combination with the main cylinders of carding engines, but
it may be employed in adjusting the position of the bearings of other
rollers, and for other purposes.
In applying my Invention to the working and clearing rollers of
carding engines, the roller bearing fits between ribs cast on the outer
side of a plate, the inner part of which fits between ribs cast on the bend
of the carding engine, the bearing, the plate, and the bend being secured
together by a bolt and nut. The roller is adjusted by a right and left
handed regulating screw, one part of which is screwed into a projection
from the bearing, and the other part is screwed into the plate, conse-
quently when the regulating screw is turned partly round the bearing
is moved to and fro in the plate.
My Invention may be modified by making the regulating screw with
a coarse and a fine thread.
And in order that my Invention may be fully understood and readily
carried into operation I will proceed to describe the accompanying Sheet
of Drawings, in which Fig. 1 represents an end view of part of a carding
engine to which my improvements are applied; Fig. 2 is a vertical
section, and Fig. 3 a horizontal section of one of my improved bearings.
a is part of the bend of a carding engine which is provided with the
three segmental ribs a¹, a², and a³. Between the ribs a¹ and a² are fitted
the segmental plates 6 which are provided with small ribs to guide the
roller bearings c. The bearing c, the plate b, and the bend a are united

page_text: together by the bolt d, the nut of which when tightened secures the
clearing roller e in its place. To the inner side of the bearing c is cast
a projection c¹, and to the outside of the plate 6 is cast the projection b¹.
The regulating screw f is made with a right and left handed thread,
one thread passing through a tapped hole in the projection 61 and the
other through the projection c¹. When it is necessary to adjust the
position of the roller e the nut of the bolt d is slackened and the regu-
lating screw f is turned partly round either in one direction or the
other to move the roller e either nearer to or further from the main
cylinder, which is shewn partly in Fig. 2. As the plate b is held
between the ribs a¹ and a³ it is evident that in turning the regulating
screw partly round the bearing c is moved from or towards the centre
of the main cylinder.
The bearing of the working roller is very similar to that above
described, the only difference being that the position of this bearing
must be regulated laterally in addition to its motion to and from the
centre of the main cylinder. This lateral motion is given by the nuts
on the segmental screw 9, one end of which is screwed into the plate b
of the bearing of the roller e, and the other end passes through a recess
in the corresponding plate of the bearing of the roller h. The regulating
screw for the bearing of the roller h is made according to a modification
of my Invention, the screw being partly with a coarse thread and partly
a fine thread. When this regulating screw is turned partly round the
motion imparted to the bearing c is equal to the difference between the
two pitches of the threads.
In applying my Invention to adjust the position of other bearings and
for other purposes, the regulating screws either with right and left
handed threads or with threads of different pitches must pass through a
fixed part of the machine as well as through the bearings or other article
to be adjusted.
By causing the regulating screws to pass through screwed holes in
the fixed article as well as through the article to be adjusted the back
lash of the screws and the play of the collars used in ordinary regulating
screws are avoided.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim regulating the
position of card rollers or other articles requiring accurate adjustment by

page_text: means of screws with right and left hand threads or with threads of
different pitches as shewn and described.
In witness whereof, I, the said Edward Lord, have hereto set my
hand and seal, this Twenty-fourth day of March One thousand
eight hundred and seventy-one.
