Lancaster, Roller Maker, for the Invention of "IMPROVEMENTS IN THE
✓ MANUFACTURE OF DRAWING ROLLERS USED IN MACHINES FOR PREPARING AND
SPINNING, AND IN THE MACHINERY EMPLOYED THEREIN."
Sealed the 8th September 1864, and dated the 17th March 1864.
PROVISIONAL SPECIFICATION left by the said Joseph Bleasdale at
the Office of the Cominissioners of Patents, with his Petition, on the
17th March 1864.
I, JOSEPH BLEASDALE, of Blackburn, in the County of Lancaster, Roller
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF DRAWING ROLLERS USED IN MACHINES FOR PRE-
PARING AND SPINNING, AND IN THE MACHINERY EMPLOYED THEREIN," to be
follows:-
In manufacturing fluted corrugated drawing rollers such as are employed in
the various machines used in preparing and spinning cotton and other fibrous
substances, no means have heretofore been adopted for polishing the corru-
[Price 8d.]

page_text: gations in order to obtain a perfectly smooth surface, which is most desirable
and essential when both the top and bottom rollers are corrugated and worked
together.
Now the first part of my Invention consists in polishing the fluted
corrugations of drawing rollers, and the second part of my Invention consists
in the following combination of machinery for effecting the said object, but
I do not limit myself to the same.
The first combination consists of a revolving roller for polishing. the corru-
gated roller, such polishing roller to be made of wood or lead, or any other
soft metal or suitable material, and with flutes to correspond with the roller
to be polished. Oil and emery or other grinding or polishing materials are
applied between the rollers, and one of them has a lateral to-and-fro
motion.
The second combination consists in the use of two flat or other surfaces
with corrugations; between these surfaces are placed a number of rollers at
proper distances apart, with oil and emery on them, one of these surfaces
moves backward and forward and laterally.
The third combination consists of a disc made of wood, lead, or any other
suitable material, the circumference of which is turned to fit the corrugated
rollers; this disc in revolving moves also up and down or to and fro like the
cutter of a wheel cutting machine, only much quicker; oil and emery are used
as above, or the to-and-fro motion may be given to the roller to be polished.
The machineryabove described is suitable for polishing cast or wrought iron
rollers; the following mode is applicable for wrought-iron rollers only:-Steel
discs similar to the above, hardened and polished, are used as burnishing
rollers to take off any sharp ridges that are left by the fluting machine.
The last part of my Invention consists in an improved mode for producing
irregular flutes for the purpose of preventing the fluting of the leather covering
of the top roller. I propose to make the irregularity in the size of the flutes
come, say, 5 or 6 times in the circumference of the roller; this may be effected
with the usual index working on an eccentric spindle. By placing a large
wheel on the spindle and a small pinion on the stud, and an index fast on the
same stud, working about ths of an inch out of the centre, the irregularity
can be repeated as often as required. This machinery will answer for fluting
rollers or for making indices for roller fluting machines.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BLEASDALE, of Blackburn, in the County of Lancaster, Roller Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of March, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Bleasdale, Her special license that I, the said Joseph
Bleasdale, my executors, administrators, and assigns, or such others as I,
the said Joseph Bleasdale, 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 THE MANUFACTURE OF DRAWING ROLLERS USED IN MACHINES FOR PREPARING
AND SPINNING AND IN THE MACHINERY EMPLOYED THEREIN," upon the condition
(amongst others) that I, the said Joseph Bleasdale, my executors'or administra-
tors, 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 Joseph Bleasdale, 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) :-
.
In manufacturing fluted corrugated drawing rollers such as are employed in
the various machines used in preparing and spinning cotton and other fibrous
substances, no means have heretofore been adopted for polishing the corru-
gations in order to obtain a perfectly smooth surface, which is most desirable
and essential when both the top and bottom rollers are corrugated and worked.
together.
Now the first part of my Invention consists in polishing the fluted
corrugations of drawing rollers, and the second part of my Invention consists

page_text: in the following combinations of machinery for effecting the said object, but
I do not limit myself to the same.
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, reference being had to the figures and letters marked thereon.
The first combination of machinery for polishing the fluted corrugations of
drawing rollers is represented in Figures 1 and 2, and it consists of a polishing
roller a, made of wood, or lead, or any other soft metal or suitable material,
and with flutes to correspond with the roller to be polished, shewn at b. Oil
and emery or other grinding or polishing materials are applied between the
rollers, and the polishing rollera has a lateral to-and-fro motion given to it by
the operator. During the operation the roller 6 is caused to revolve in a
lathe or by other suitable means, and in revolving the roller b imparts rotary
motion to the roller a, which is supported in the frame c, fixed in a handle d,
which is similar to the handles of ordinary turning tools.
Figures 3 and 4 represent a modification of this part of my Invention. In
this arrangement the roller b is acted upon by three polishing rollers a, which
revolve in the jaws of the clip e; the roller 6 is turned round in a lathe or
otherwise, and the rollers a are moved to and fro in the direction of their axes
by the operator, who gives the requisite pressure by the handles at the
extremities of the clip.
The second combination of machinery for polishing the fluted corrugations
of drawing rollers is shown in Figure 5, and it consists in the use of two flat
or other surfaces with corrugations, as shewn at f,f; between these surfaces
are placed a number of rollers 6, at proper distances apart, with oil and emery
on them; one or both of the surfaces fare moved backward and forward, and
laterally, to effect the polishing of the rollers b.
The third combination of machinery for polishing the fluted corrugations of
drawing rollers is shewn in Figures 6, 7, 8, and 9, and it consists of a disc made
of wood, lead, or any other suitable material marked g, the circumference of
which is turned to fit the corrugated rollers; this disc in revolving moves also
up and down or to and fro, like the cutter of a wheel cutting machine, only
much quicker. Oil and emery are used as above, or the to-and-fro motion
may be given to the roller to be polished. In Figures 6 and 7 the roller 6 to
be polished is supported in stands fixed to a plate h, which is moved to-and-
fro along the bed by a screw and nut, as in slide lathes, or in any other
convenient manner. The disc g, see also Figures 8 and 9, is fixed to the
spindlej, revolving in a bush, which can be raised or lowered to suit discs and
rollers of different diameters. In Figure 6 I have shewn a rack on the

page_text: plate h gearing in a pinion, which by means of a pair of bevel wheels gives
the requisite rotary motion to the disc g, but the disc may be turned round
by a pulley on the spindle j, or in any other convenient manner.
The machinery above described is suitable for polishing cast or wrought
iron rollers, the following mode is applicable for wrought-iron rollers
only Steel discs similar to the above, hardened and polished, are used as
burnishing rollers, to take off any sharp ridges that are left by the fluting
machine, but the discs g may be made with notches like a cutter, as shewn
by dots in Figure 8, to scrape off or remove any sharp ridges on the rollers;
by this means the discs would act as cutters and burnishers.
The last part of my Invention consists in an improved mode of producing
irregular flutes in drawing rollers for the purpose of preventing the fluting
of the leather covering of the top rollers. I prefer to make the irregularity
in the size of the flutes recur, say, five or six times in the circumference of
the roller, but the number of repeats is not material. In performing this
part of my Invention the usual index, working on an eccentric spindle,
may be employed, or it may be effected by placing a large wheel on the
spindle, and a small pinion on the stud; an index is fast to the said pinion,
but about three-sixteenths of an inch out of the centre. Figures 10 and 11
represent part of an ordinary fluting machine, to which this arrangement
is applied. b is the roller to be fluted with irregular flutes; the roller is
supported on the table ; the end of the roller b fits on the spindle /, which
is turned round by the pinion m, which gears into the wheel n fixed on the
spindle; this wheel and pinion are in the proportion of five to one, but
any other proportion may be given. To the pinion m is fixed the eccentric
index q, which is turned partly round at every to-and-fro motion of the
table by an incline projecting from the table acting on the lever r, which
causes the catch s to move the index one tooth, as the teeth of the index
are equal in length, and as the index is eccentric to the pinion m, by which
the rollers bare turned slowly round, it is evident that the flutes or grooves
cut in the roller by the ordinary tool will be alternately finer and coarser,
the irregularities in the flutes depending upon the degree of eccentricity
of the index. I wish to observe that this machinery will answer for fluting
rollers or for making indices for roller fluting machines.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim,―
First, the polishing by machinery of the fluted corrugations of drawing
rollers, for the purposes set forth.
Secondly, the various combinations and arrangements of machinery for

page_text: polishing the fluted corrugations of drawing rollers, as shewn and described
or any modifications of such machinery.
And, lastly, I claim the improved machinery shewn and described in
reference to Figures 10 and 11 for producing in regular flutes or grooves on
drawing rollers, or for making the indices of roller fluting machines.
In witness whereof, I, the said Joseph Bleasdale, have hereto
set my hand and seal, the Thirteenth day of September, One
thousand eight hundred and sixty-four.
JOSEPH BLEASDALE. (L.s.)
