Year: 1883

page_text: LETTERS PATENT to Percy Henry Marriott and James Hall of Stockport in
the County of Chester for an Invention of IMPROVEMENTS IN PIRN AND
SPOOL WINDING MACHINES
PROVISIONAL SPECIFICATION left by the said Percy Henry Marriott and
James Hall at the Office of the Commissioners of Patents on the
23rd February 1883.
PERCY HENRY MARRIOTT and JAMES HALL of Stockport in the County of
Chester "IMPROVEMENTS IN PIRN AND SPOOL WINDING MACHINES"
This Invention has for its object to secure a more firmly and evenly wound pirn
or spool and to reduce the friction at present caused by the rubbing of the yarn
against the surface of the slotted cup or its equivalent now employed.
In carrying out our invention we dispense with the before mentioned slotted cup
or its equivalent and substitute therefor two or more conical or cylindrical rollers
When conical rollers are used we employ them running freely on pivots in fixed
bearings or on fixed pins or spindles, and with their axes either horizontal, vertical
or at any required angle to the axis of the pirn or spool When the axes of the
rollers are horizontal each roller is the frustrum of a cone the apex of which is in
the axis of the pirn When the axis of the roller is vertical the base of the cone is
placed downwards-When the axes of the rollers are in any position between the
horizontal and vertical, conical or cylindrical rollers may be used-The cylindrical
rollers are free to rotate in fixed bearings or upon fixed pins or spindles similarly
to the conical rollers. If conical rollers are used in the inclined position they form
frustra of cones the apexes of which meet at a point in the axis or the produced
axis of the pirn or spool.

by the said Percy Henry Marriott and James Hall in the Great Seal Patent
Office on the 20th August 1883.
PERCY HENRY MARRIOTT and JAMES HALL, of Stockport, in the County of
Chester "IMPROVEMENTS IN PIRN AND SPOOL WINDING. MACHINES."
This invention has for its object to secure a more firmly and evenly wound pirn
or spool and to reduce the friction at present caused by the rubbing of the yarn
against the surface of the slotted cup or its equivalent now employed. In carrying
out our invention we dispense with the before mentioned slotted cup or its
equivalent and substitute therefor two or more conical or cylindrical rollers.
When conical rollers are used we employ them running freely on pivots in fixed
bearings or on fixed pins or spindles, and with their axes either horizontal, vertical
or at any required angle to the axis of the pirn or spool. When the axes of the
rollers are horizontal each roller is the frustrum of a cone the apex of which is in
the axis of the pirn. When the axis of the roller is vertical the base of the cone is
placed downwards. When the axes of the rollers are in any position between the
horizontal and vertical, conical or cylindrical rollers may be used. The cylindrical
rollers are free to rotate in fixed bearings or upon fixed pins or spindles similarly
to the conical rollers. If conical roilers are used in the inclined position they form
frustra of cones the apexes of which meet at a point in the axis or the produced
axis of the pirn or spool.
In order that our invention, may be more readily understood and carried into
effect we have hereunto annexed a sheet of drawings marked with letters of
reference, corresponding letters indicating the same or corresponding parts in the
various figures.
We have selected for illustrating our invention two convenient and practicable
forms thereof. Fig. 1 shows in elevation and Fig. 2 in plan an arrangement in
which conical rollers are used. Fig. 3 shows in elevation and Fig. 4 in plan an
arrangement in which cylindrical rollers are used. In Figs. 1 and 2 the conical
rollers bbbb are bored axially and are free to rotate upon the equidistant vertical
pins cccc which are fixed to a base plate d, the latter being attached to the
frame top g in the place usually occupied by the slotted cup herein before referred
to. The plate d is provided with a hole f for the passage of the spindle and is
attached to the frame top by the bolts ii or by equivalent means.
Four rollers
are shown in the figures, but three or more may be employed as is most convenient.
The foregoing description of Figs 1 and 2 applies also to Figs. 3 and 4 save that
cylindrical rollers a a a are substituted for the conical rollers bbbb and that the
pins upon which the rollers rotate are placed at an angle with the axis of the pirn
or spool.
:
To secure greater rigidity the tops of the pins c c may be attached to a segment
of a flat metal ring h h as shown in Figs 3 and 4.-
To wind yarn on paper tubes, the tubes may be passed upon the pirn bobbin
before winding after which the bobbin may be withdrawn as is well understood.
Having described the nature of the invention and in what manner the same may
be performed, we would have it to be understood that we do not confine ourselves
to the precise details hereinbefore described and illustrated on the accompanying

page_text: drawings, as the same may be varied without departing from our invention, and
that what we claim is:
The use of three or more conical or cylindrical rollers substantially as and for the
purposes herein before set forth and described and as typically illustrated on the
accompanying sheet of drawings.
In Witness whereof I, the said Percy Henry Marriott on my own behalf and
on behalf of the said James Hall have hereunto set my hand and seal this
Eighteenth day of August A.D. 1883.
