page_text: LETTERS PATENT to John and George Dakin, both of Heywood, in the
County of Lancaster, Roller Coverers, for the Invention of "IMPROVE-
MENTS IN MACHINERY EMPLOYED IN COVERING TOP ROLLERS USED IN
PORDADING SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said John and George Dakin
at the Office of the Commissioners of Patents, with their Petition, on the
28th July 1860.
We, JOHN and GEORGE DAKIN, both of Heywood, in the County of
Lancaster, Roller Coverers, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY EMPLOYED IN COVERING TOP ROLLERS
IN PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER FIBROUS
MATERIALS," to be as follows:-
The object of this Invention is to facilitate the operation of covering or
placing the tubes of flannel and leather or other suitable materials on the
top rollers of machines used in preparing, spinning, and doubling.
In
performing our Invention we make use of a rack or a slide moved by screw or
other equivalent agent, to which a to-and-fro motion is given by gearing
moved by hand or power; to this rack is fixed a trough to contain the top
roller to be covered, and to the end of the trough is fixed the circular set of

adjustable stop, against which the roller is brought when the rack is in motion,
and by which the roller is pushed through the set of springs; the tube of
flannel or leather is thus put on the boss of the roller. The machinery may
be modified by reversing the motions, or by making the trough and set of
springs stationary, and pushing the roller through them by rack or other
equivalent agent..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John and George Dakin in the Great Seal Patent Office
on the 26th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
and GEORGE. DAKIN, both of Heywood, in the Gounty of Lancaster, Roller
Coverers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John and George Dakin, Her special licence that we, the said John and
George Dakin, our executors, administrators, and assigns, or such others
as we, the said John and George Dakin, 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 "IMPROVEMENTS IN MACHINERY EMPLOYED IN 'COVERING TOP
ROLLERS USED IN PREPARING, SPINNING, AND DOUBLING COTTON AND 'OTHER 'FIBROUS
MATERIALS," upon the condition (amongst others) that we, the said John and
George Dakin, our executors or administrators, by an instrument in writing
under our, or 'their, or one of our or their hands and seals, should particu-
larly 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 imme→
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John and George Dakin, do hereby
declare the nature of our said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
--
The object of this Invention is to facilitate the operation of covering or
placing the tubes of flannel and leather or other suitable materials on the top
rollers of machines used in preparing, spinning, and doubling. In performing
our Invention we make use of a rack or a slide moved by screw or other
equivalent agent, to which a to-and-fro motion is given by gearing worked by
hand or power; to this rack is fixed a trough to contain the top roller to be
covered, and to the end of the trough is fixed or connected the circular set of
springs on which the tube of flannel or leather is put in the manner now
customary in covering rollers by hand. The machine is furnished with an
adjustable stop, against which the roller is brought when the rack is in
motion, and by which the roller is pushed through the set of springs, the tube
of flannel or leather is thus put on the boss of the roller. The machinery may
be modified by reversing the motions, or by making the trough and set. of
springs stationary, and pushing the roller through them by rack or other
equivalent agent.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is a side elevation, partly in section, of our improved machinery;
and Figure. 2. is an end view of the same, also shewn partly. in section..
a are two side frames, which are bolted to the table or bench supporting
the machine; these frames are connected by the plates b, in which are holes
for the slide bed c to pass through; the slide bed c is also secured to the table
or bench by bolts passing through the pillars d. e is a rack sliding in the
groove in the slide bed c, and this rack is moved to and fro in the slide bed
by the handle f¹ fixed on the shaft f, to which is fixed the pinion 9 gearing
into the wheel h, to which is fixed or cast the pinion i gearing into the teeth
of the rack e. At one end of the rack e is jointed the trough j, to which the
circular set of springs k are attached; similar springs are used in covering
rollers by hand; the trough j is held on the rack by the catch 1, which is
hinged at m, and when it is requisite to change the trough to suit the length
of top roller to be covered, the catch is raised into the position shewn in
dotted lines, to allow the trough to be taken out and a fresh one put in its
place; the adjustable stop n is held by a set screw in one of the plates 6; this
stop can be moved longitudinally according to the length of the top roller to
be covered. When our improved machinery is in operation, the top roller o
to be covered is placed in the trough j, as shewn in Figure 1; this top roller

page_text: is suitable for a mule, and the tube of flannel or leather p, shewn by dotted
lines, is put partly on the set of springs k, the attendant then turns the
handle f¹, so as to cause the rack e to move in the direction of the arrow in
Figure 1; the end of the top roller, is thus brought against the end of the stop-
piece n, which, as the rack continues to move, brings the springs k and the
tube of flannel or leather p over the top roller o; the motion of the rack is
continued until the top roller drops through the springs, after which, by
reversing the motion of the handle f¹, the rack e is brought back into the
position shewn in Figure 1, and another top roller is supplied to the trough j.
By this means the operation of covering top rollers is greatly accelerated, and
the coverings can be put on much tighter than is possible by manual labour,
as now customary. The machinery may be considerably modified, and the
motions may be reversed, that is to say, the trough j and springs k may be
stationary, and the top roller pushed through them.
Having thus stated the nature of our Invention, and described a convenient
mode of carrying the same into operation, we wish to observe that we do not
limit ourselves to the details given; but we claim the improvements in
machinery shewn and described, or any modification thereof, for covering
the top rollers used in preparing, spinning, and doubling cotton and other
fibrous materials.
In witness whereof, I, the said John Dakin, have hereunto set my
hand and seal, this Twenty-fourth day of January, in the year of
our Lord One thousand eight hundred and sixty-one.
