I. JOSEPH BLEASDALE, of Accrington, in the County of Lancaster, Roller
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF FLUTED ROLLERS FOR PREPARING AND SPINNING
FIBROUS MATERIALS, AND IN MACHINERY FOR THE PURPOSE," to be as follows:-
The first part of my Invention relates to an improved mode of making fluted
rollers for preparing and spinning fibrous materials. by which a more smooth
and perfect flute is formed than by the ordinary process, and it consists in first
fluting the rollers by the ordinary cutting process, and then finishing them by
a milling process, the flutes of the mills employed being of the same pitch as
those formed by the cutting process.
The second part of my Invention relates to improved mechanism for fluting

arranged so as to act simultaneously upon the roller to be fluted, which is placed
between them, so that the pressure put by each mill upon the roller is received
and resisted by one or more of the other mills, and by this means the milling
process is carried on without pressure upon the bearings of the roller, which
may either revolve and give motion to the mills in the ordinary manner, or the
roller may remain stationary (excepting end movement, which it may or may
not receive as arranged), and the mills may rotate on their own axis, and
revolve round the roller by having their bearings arranged so as to be carried
by a rotatory chuck.
The third part of my Invention relates in the inanufacture of such fluted
rollers as are intended to work together in pairs, both rollers being fluted. In
this class of fluted drawing rollers it is essential-that: the-flutes be uniform.in
size and shape, and my Invention consists in forming such fluted rollers by first
cutting the flutes by a planing process, and then finishing. to equalize and
polish them by a series of mills.-such as those above referred to in the second
part of this Provisional Specification. such mills being "set up" against the
roller to a fixed stop by screws or other suitable arrangements, so that the
grooves in each roller will be milled to the same uniform pitch and depth.

the Channel Islands, and Isle of Man, an Invention of "IMPROVEMENTS IN

page_text: THE MANUFACTURE OF FLUTED ROLLERS FOR PREPARING AND SPINNING FIBROUS
MATERIALS, AND IN MACHINERY FOR THE PURPOSE," upon the condition (amongst
others) that I. the said Joseph Bleasdale. 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.
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 per-
formed, to be particularly described and ascertained in and hy the following
statement and accompanying Drawings, that is to say :---
The first part of my Invention relates to an improved mode of making fluted
rollers for preparing and spinning fibrous materials, by which a more smooth
and perfect flute is formed than by the ordinary process, and it consists in first
fluting the rollers by the ordinary cutting or planing process. and in then
finishing them by a milling process, the flute of the mills employed being of
the same pitch as those formed by the cutting or planing process.
In carrying out this part of my Invention first flute the rollers by a
machine similar to those in ordinary use, and then mill them by a machine
similar to that described in the Specification of the Patent granted to William
Weild, numbered 2139, and dated the Twentieth day of September. in the
year of our Lord One thousand eight hundred and fifty-nine, or by improve-
ments since made upon it, whereby the mills are pressed upon the rollers by
weighted levers, or by the improvements herein-after described under the next
division of this Specification.
The second part of my Invention relates to improved mechanism for fluting
rollers by the milling process, and consists in the employment of three or more
mills, arranged so as to act simultaneously upon the roller to be fluted, which
is placed between them, so that the pressure put by each mill upon the roller
is received and resisted by one or more of the other mills, and by this means
the milling process is carried on without pressure upon the bearings of the
roller, which may either revolve and give motion to the mills in the ordinary
manner, or the roller may remain stationary (excepting end movement, which
it may or may not receive as arranged), and the mills may rotate on their
own axis, and revolve round the roller by having their bearings arranged so as
to be carried by a rotatory chuck.
I prefer to carry out this part of my Invention by means of arrangements
illustrated in the accompanying Drawings by Fig. 1 a plan. and Fig. 2 a cross

page_text: sectional view. a represents the lathe bed; b, the carriage; . stands fixed to
the carriage by a bolt (c). Each stand (c) carries the fulcrum (¹) of a
lever d. into one end of which a holder (d) is secured, in which the axis of
the upper mill works. The other end of the lever (d) is jointed with a rod (d³).
connecting it with the end of another lever e, having its fulcrum on a shaft or
axis (e). carried in brackets (b) from the carriage b. The pressure is put
upon the upper mill by means of a weight (e) on the lever e. On the upper
side of the carriage (b) there are two other brackets or stands (69), which from
the bearings of an excentric shaft. On one end of this shaft a spur wheel /' is
fixed, geering with a pinion on a shaft or axis f. upon which a handle f' is
placed, by which means the excentric shaft can be turned so as to come
against each of the levers d. and thus cause them all to be simultaneously
depressed, and the upper mills to be lifted from the work. The carriage bis
traversed by means of the screw 9. driven by suitable geer from the headstock
of the lathe, and the roller to be milled is connected with the lathe spindle, so
as to be rotated by means of a "universal joint coupling," which thus admits
of a slight ascent or descent of the roller above or below the centre of the.
lathe spindle.
The mechanism just described constitutes the improvements upon that
meclianism for milling described in the aforesaid Specification of William
Weild, and herein-before referred to, and my improvements upon it consists in
applying instead of mere bearings to receive the journals of the roller to be
fluted, two bearings, each carrying a mill. Each of these bearings is secured
to the stand c, as shewn, and slots are provided for adjustment. the lateral
pressure being sustained by means of the adjustable set screws h¹. The three
mills are all fixed in the same plane, and as near as possible 120 degrees
apart, the roller being placed between them, as shewn.
is put on the roller by the upper mill is thus received by the two lower
mills, and thus all the three mills assist in the milling process without.
straining or putting pressure on the journals of the rollers. Of course there
may be several sets of mills, one for each boss of the roller if required, all
operating at the same time.
The pressure which
The third part of my Invention relates to the manufacture of such fluted
rollers as are intended to work together in pairs, both rollers being fluted. In
this class of fluted drawing rollers it is essential that the flutes be uniform in
size and shape, and my Invention consists in forming such fluted rollers by
first cutting the flutes by a planing process, and then finishing to equalise and
polish them by a series of mills, such as those herein-before referred to under
the second division of this Specification, such mills being set up against the

page_text: roller to a fixed point or stop by screws or other suitable arrangements, so
that the grooves in the roller will be milled to the same uniform pitch and
depth.
In carrying out this part of my Invention, i first dute the roller in the
ordinary machine, with flutes as near as possible to the size and shape
required, and then I prefer, to equalise and finish them by means of the
mechanism which is illustrated on the accompanying Sheet of Drawings by.
Fig. 3, a plan; Fig. 4, a cross sectional elevation; Fig. 5, a front elevation;
and Fig. 6, a plan section. a is the lathe bed; b, carriage; c, stand fixed on
carriage, and secured by bolts; in the upper part of this stand a slide d
is fitted so as to slide vertically, and is held by suitable V-pieces (d')
secured by set screws. and connected with this vertical slide is a screw
passing through a hole in the upper part of the stand, being arranged so as
to rotate, but not to move vertically, and to the upper end of this screw
a handle () is fixed, which carries a pin (d) fitted so as to slide in the
hollow handle, and he acted upon so as to be forced outwards by means of an
helical spring. When the handle is turned the pin will pass over a series of
holes in a circular plate () formed on the upper part of the stand, and when
the handle is moved so as to bring the pin over a hole it will enter and prevent
the handle froin turning by accident. On each side of the vertical slide (d) a
series of projections are formed, into which set screws (e) are placed at an
angle to the face of the slide, as shewn, the points of the set screws acting
against the bevelled edges of slides (e), forming the bearings of the upper
mill. The end adjustments of the slides (e) are given by set screws e in
projections from the vertical slide d. The bearings of the two lower mills are
placed at an angle of 120 degrees from the upper mill, but are arranged and
adjusted by similar means. In operating with this mechanism the vertical
slide d is lifted so as to admit the roller by turning the screw handle . and
when the roller to he operated upon is inserted the slide is screwed down, and
the handle is turned as the milling process proceeds. till the pin in the handle

is brought over the hole fixed upon to give the required depth of flute.
some cases the mills may be narrow and traversed along the roller. but in
others they may be of sufficient breadth to cover an entire boss, so that no
traversing motion will be required.
I have now particularly described the nature of my invention. and the mode
in which the same may be carried into effect, and wish it to be understood that
I claim as my Invention,-
Firstly, the fluting of rollers for preparing and spinning fibrous materials by
first cutting the flutes by the ordinary cutting or planing process, and subse

page_text: quently finishing them by a milling process, as herein-before described under
the first division of this Specification.
Secondly, I claim the use of three or more mills when used for milling
rollers for preparrng or spinning fibrous materials, as herein-before described
under the second division of this Specification.
Thirdly, claim the process and means of manufacturing such fluted rollers
as are intended to work together in pairs by a planing and milling process.
ás herein-before explained and described under the third division of this
Specification.
In witness whereof, I, the said Joseph Bleasdale, have hereunto set
my hand and seal, this Nineteenth day of November, in the year of
our Lord One thousand cight hundred and sixty-one.
