COMPLETE SPECIFICATION.
Improvements in Machines for Varnishing Rollers used in Cotton
Machinery.
I, SAMUEL GREEN, of Park View, Lees Road, Mossley, in the County of
Lancaster, Cotton Mill Manager, 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:-
This invention relates to improvements in machines for varnishing leather
rollers used in cotton machinery and has for its object to. provide means whereby
any length and solid or loose boss rollers can be quickly and uniformly coated
with varnish without having as hitherto to exchange the chucks which hold and
rotate the rollers, thus saving a great deal of time and labour.
And in order that my invention may be more fully understood I have caused to
be appended hereunto" one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a side view, Fig. 2 a
longitudinal section, and Fig. 3 a plan of my improved roller varnishing machine.
In carrying out my invention and referring to the figures generally, I employ
a bed a having two bearings & & c.
In the bearing c I mount a spindle d carrying at its outer end a driving
pulley e and in the bearing 6 I eniploy a bar f adapted to slide longitudinally.
The inner ends of the said spindle and bar are each formed or furnished with
a chuck g&h respectively, formed externally or internally or both externally and
internally conical as shown in the drawing and adapted to receive, externally the
loose boss rollers and internally the solid rollers to be varnished as shown
respectively in dotted lines Figs. 1 & 2.
In the present instance the driving spindle chuck is formed part of the
driving spindle d and made slightly less taper than the chuck h on the bar f so as
to grip the roller by frictional contact sufficiently to rotate it. The latter chuck
is formed with a shank & having a pointed end ¿¹ adapted to rotate loosely against
a steel disc in the bar f.
The chuck his pressed against the respective end of the roller in the machine by
a spring 1, one end of which is attached to projections m formed on the bearing b
and the other to an arm secured to the bar f and guided by a stud o secured
to the bearing b.
In order to render the machine usable for different lengths of rollers, the bar f
is rendered longitudinally adjustable. in its bearing b, say by means of a pin t
passed through a hole g formed in the boss n' of the arm n and by two or more
holes r formed at a suitable distances apart from each other in the said bar through
one of which the said stud is passed, see more particularly Fig. 2.
The arm n is formed at its top with a knobs which facilitates the longitudinal
movement of the bar when changing the rollers whilst the head o¹ on the stud o
prevents the arm n, being drawn out too far.
In lieu of the said pin and holes a set screw may be employed in the boss n¹
of the arm n, or a weight in lieu of the spring / as will be readily understood.
The rollers are placed into the machine described by first withdrawing the bar f¨

page_text: slightly, then placing the roller end into the respective chuck and afterwards
the other end into the driving chuck, whilst in removing the roller, after slightly
pressing back the bar f, the roller is first taken out of the driving chuck y and
then out of the loose chuck h.
If desirable the said chucks may be formed conical externally only to receive
only loose boss rollers, or internally only to, receive solid, rollers only, as will be
readily understood.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
i 4410**
1st. In machines for varnishing rollers, the use of chucks for holding the
rollers, formed conical internally or externally or both, all substantially as and
for the purpose set forth.
2nd. In a machine for varnishing rollers, the combination of two internally
or externally or double coned chucks g, one being rotated by the driving shaft
and the other loosely in a longitudinally adjustable bar f, by the roller in. the
chuck h, all substantially as set forth.
3rd. In a machine for varnishing rollers such as specified in Claim 2, the
combination with the bar f of an arm n placed under the influence of a spring /
or the like adapted to force the chuck against the roller end and rendered
adjustable on the said bar, for acommodating various lengths of rollers to be
varnished, all substantially as set forth.
