Particularly Applicable to Rollers Employed in Machines for
Preparing and Spinning Fibrous Substances.
I ROBERT WILDING of Poulton-le-Fylde in the County of Lancaster, Engineer
do hereby declare the nature of this invention to be as follows:-
The principal object of this invention is to construct a simple and convenient form
of lathe to be used in varnishing the leather covered rollers employed in machines
for preparing and spinning cotton and other fibrous substances, but the improved
apparatus may also be employed for varnishing or painting other kinds of rollers or
similar articles.
°
On a convenient bed or table I mount a headstock carrying a spindle on which is
mounted loosely a driving pulley or drum to which a constant revolving motion is
imparted by means of an endless band or strap from any convenient driver.
The boss of this pulley is formed with an internal cone and in connection therewith
is an external cone which slides on a feather or key upon the spindle. This sliding
cone is made with a neck or groove which is embraced by a fork forming one arm of
a bell crank lever. The other arm of this lever rests upon a small cam which can be
turned by a button or thumb piece, so that by a slight turn of the latter the cone can
be moved into or out of gear with the revolving pulley.
In connection with the fixed headstock is a bar upon which is mounted an
adjustable headstock carrying a spindle or centre which can slide longitudinally but
does not revolve.
It is acted upon by a spiral spring.
The running spindle is made with a socket to fit the largest size of roller end and is
provided with movable chucks to fit the different smaller sizes. The socket and the
chucks are faced with india rubber. The roller can be easily fitted and removed by
drawing back the spring centre and when the cones are in gear the pressure of the
spring and the adhesion of the india rubber will be sufficient to cause the roller to turn
with the spindle whilst being varnished.

Particularly Applicable to Rollers Employed in Machines for
Preparing and Spinning Fibrous Substances.
I ROBERT WILDING of Poulton-le-Fylde in the County of Lancaster Engineer
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
The principal object of this invention is to construct a simple and convenient form
of lathe to be used in varnishing the leather covered rollers employed in machines for
preparing and spinning cotton and other fibrous substances but the improved
apparatus may also be employed for varnishing or painting other kinds of rollers or
similar articles.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof. Fig. 1 on the
drawings is an elevation (partly in section) and Fig. 2 a plan view of my improved
apparatus. Fig. 3 is a section (on an enlarged scale) of a portion of the apparatus
hereinafter more particularly referred to.
On a convenient bed or table a I mount a fixed headstock 6 carrying a spindle c
on which is mounted loosely a driving pulley or drum d to which a constant revolving
motion is imparted by means of an endless band or strap from any convenient driver.
The boss e of this pulley d is formed externally conical, and in connection therewith
is an internal cone f which slides on a feather or key g upon the spindle c.
sliding cone is made with a neck or groove which is embraced by a fork / forming
one arm of a bell crank lever..
This
The other arm of this lever rests upon a small cam k (see Fig. 3) which can be
turned by a button or thumb piece so that by a slight turn of the latter the cone f
can be moved into or out of gear with the conical boss of the revolving pulley d, a
light spring, holds the armi against the cam k. In connection with the fixed
headstock is a bar m upon which is mounted an adjustable headstock n carrying
a spindle or centre o which can slide longitudinally but does not revolve. It is acted
upon by a spiral spring p inside the headstock.
The running spindle c also the spindle o in the adjustable headstock are both made
with a socket cand c, to fit the ends of the largest size rollers and are also each
provided with movable chucks to fit various smaller sized rollers. Two of these chucks
are shown at q, and q1,q being fitted into the socket of the running spindle cand q¹ fitted
into the socket of the spindle o in the adjustable headstock. Some of the smaller
roller chucks which fit into the socket of the running spindle c are preferably faced
with india rubber or other suitable material.

page_text: The rollers (a small sized one shown in dotted lines in figures 1 and 2) can be
easily fitted and removed by drawing back the spring centre o, and when the cones e
and fare in gear the pressure of the spring p pushing the roller against the india
rubber face of the chuck q in the running spindle c will be sufficient to cause the
roller to turn with the spindle while being varnished.
In the case of large and heavy rollers the chucks fitting into the running spindle o
are provided with a set screw to fix the roller end in the chuck and cause it to turn
with the spindle while being varnished.
The roller being fitted in the apparatus (as shown dotted on Fig. 1.) is caused
to revolve whilst the varnish or paint is applied by a brush or other suitable means,
and a very even and smooth surface is thereby obtained.
In some cases (especially for heavy work) I provide the apparatus with a bell
crank ŕ and treadles for withdrawing the spring spindle or centre o.
Having now particularly described and ascertained the nature of my said
invention and in what mauner the same is to be performed I declare that what
I claim is
The combination of parts forming the improved apparatus to be used in varnishing
rollers and the like substantially as hereinbefore particularly described and illus
trated by the drawings annexed.
