Improved Machine for Covering Rollers used in Textile Machinery.
I JAMES SHEPHERD of Holly House Davenport near Stockport in the County
of Cheshire, Engineer do hereby declare the nature of this invention to be as
follows:-
--
My invention relates to apparatus for covering the top rollers used in connection
with textile machinery, and is specially designed to meet the requirements of my
Patent No. 4592 year 1889 for Improvements in Coverings for Rollers used in
Textile Machinery."
To cover rollers having one or more bosses upon the same spindle with paper in
the form of a continuous tape or band, in such inanner that the paper is wrapped
or wound on evenly, and perfectly accurate in length upon the boss or bosses of a
roller at one operation, and with the necessary amount of elasticity, I construct a
machine composed of a frame of cast iron, the sides being braced together by bolts
or tie rods.
A metal cylinder of about 18 inches long and 6 inches diameter is fitted on a
shaft fixed in the front portion of the frame, the ends of the shaft revolving in steps
or bearings.
The surface of this cylinder is covered with an elastic body such as vulcanite or
india-rubber, and must be turned or ground up perfectly true over its outer surface.
The object of this clastic surface on the cylinder is to take up the inequalities
that exist in the diameters and form of roller ends or pivots, and that without such
mode of compensation two or more bosses on the same roller could not be equally
covered at one operation.
In the frame behind the cylinder, and parallel with it I fit another shaft in
suitable bearings, upon which are mounted two quadrant shaped levers secured to
the shaft by set screws, so that they can be easily moved from one position on the
shaft to another. The end of each quadrant is fitted with a moveable and adjusting
slide bearing, arranged to receive the pivots or journal ends of a roller as it lies in
position upon the elastic surface of the cylinder below it. Upon this same shaft I
fix another lever to be secured in any position by a set screw, and having a curved
arm comes under the cylinder to the front of the machine. This lever works the
quadrants, and is weighted to keep the roller in process of being covered in close
contact with the elastic surface of the cylinder.
Within the frame of the machine at a higher level than the quadrant shaft I fix
a screwed mandrel or shaft held in position between shaped centres on screwed
studs that go through either side of the frame and which are employed as tension
stuls for slackening and tightening the mandrel upon which the coils or reels of
paper to be used are fixed, and so govern the stretch or tension upon the paper as it
is taken from the reels or coils on to a roller in process of being covered.
At any suitable position between the screwed mandrel and the main cylinder, I
employ one or more guide rollers working in bearings in the frame sides. These
rollers conduct the paper strips or tapes from the coils to the roller in process of
being covered.
On one end of the main cylinder shaft a worm may be fixed working into a
suitable wheel carrying an index plate, or stud actuating the striking of a bell to
indicate the amount of work done, or the machine may be worked without such
arrangement, either by hand, or by strap.

Improved Machine for Covering Rollers used in Textile Machinery.
1 JAMES SHEPHERD of Holly House Davenport near Stockport in the County
of Cheshire 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 :—
My invention relates to apparatus for covering the top rollers used in connection
with textile machinery, al is serially designed to meet the requirements of my
Patent No. 4592 year 1889 for Improvement in Coverings for Rollers use în
Textile Machinery."
vi
To cover top rollers having one or more bosses (fixed or lunse) upon the same
spindle with paper in the form of a continuous tape or ribbon in such manner that
the paper tape or ribbon may be wrapped or wound on to the loss or bosses of a
roller so evenly and accurate in length that the separate bosses of a roller are
exactly of the same diameter, and having an equal amount of spring or elasticity 1
construct for the purpose a machine composed of a framework of cast iron, the two
sides being braced together by tie rods or bolts.
To the front portion of this frame 1 fix a truly bored and turned metal cylinder
of any required length and diameter, fitted on a shall to revolve in suitable bearings
on the frame side. The surface of this cylinder is covered with an elastic body
such a- india-rubber, and afterwards turned or ground up perfectly true over the
outer or elastic surface.
The object of this elastic covering on the mictal cylinder is to obtain grip or
driving power to turn the roller in process of being covered with the paper tape,
and also to art as a compensating nudium to the inequalities that exist in the shapes
and diameters of the pivot ends of the rollers or spindles.
Without some method of taking up these irregularities, two or more bosses on the
one roller could not be covered sufficiently accurate to be of the same diameter.
Within the frame behind the main cylinder and parallel with it I fix a shaft in
suitable bearings on which are nummited two quadrant or other shaped levers fitted
with keys or set screws so that they may easily be moved about in the shaft, and
made firm in their position.
:
The front end of each quadrant or lever on the underside is slotted in a ^ groove
to carry the pivot or spändle end of a top roller in process of covering or loose
holding pieces may be attached to the quadrants or levers as a means to facilitate
adjustment of a roller.
Upon this same shaft between the quadrants a bracket is fixed to carry a rod or
bar of iron that comes under the main cylinder to the front of the machine, and
which is weighted by dises of metal to any required load. This lever raises and
lowers the quadrants that holds a top roller to the elastic surface of the main
cylinder below it, and the weight at the end of the bar or lever determines the
degree of compression or elasticity given to the folds of paper wrapped on a roller
in process of covering.
Within the frame of the machine at a higher level than the quadrants fix a
screwed mandrel shaft carried on cone centre ends of regulating screws that go
through either side of the frame.
The reel or reels of paper to be used for covering rollers are placed on the
screwed mandrel, and are held in their required position by nuts and washors. The
amount of stretch or tension put upon the paper in process of unreeling is governed
by the side regulating screws.
At any suitable position in the frame, one or more light metal or timber rollers
may be used as guides to conduct the paper tape or ribbon from the reel or reels on
to the top roller in process of covering.
To ascertain correctly the finished diameter of a covered roller, a recording

page_text: apparatus may be attached to the machine by fixing as shewn in the drawing
herewith a swinging feeler in the shape of a metal pointed rod suspended from a
light shaft above the main cylinder. The pointer can be made telescopic and
adjustable as a gauge to suit any dimension of roller in process of covering.
Having now described the nature of my invention I will proceed by reference to
the accompanying drawings to describe the several parts as arranged.
The same letters of reference indicate the same parts in the several figures of the
drawings.
Figure 1 is an elevation in section. Figure 2 is a plan. Figure 3 is an end
elevation on the working or driving side. Figure 4 is a front elevation of the
inachine.
"A" represents coils or reels of paper tape. "B" a screwed mandrel that
carries the coils or reels of paper tape, with nuts and washers for adjusting and
securing the same in position. "C" regulating screws with cone shaped ends for
receiving and carrying the screwed mandrel and for giving the tension necessary in
unwinding the paper coils or reels. "D" the main metal cylinder covered with an
elastic body such as india-rubber. "E" quadrant levers for holding in position a
roller in process of covering. "F" a shaft from the frame sides for carrying the
quadrant levers, and also for carrying the fixing "G" into which the lever bar H
is secured. "" are disc weights of metal which may be increased in number or
reduced according to the amount of compression given to the paper wrapped on the
top roller "K." The loose bracket "L" slides over the shaft "M" and is fitted
with an adjustable pointer for gauging purposes. "N" a roller, or paper carrier
of which one or more may be employed. "O" stretchers or stays to bind the
frame sides marked X firmly together." "P" spur pinion wheels arranged as double
gearing working from a small to a larger driver on the main cylinder shaft as a
means to obtain increased hand power.
e
Having now particularly described and ascertained the nature of my invention,
and the means I adopt in carrying the same into practice what I claim is :-
First. The use of an elastic covered cylinder as a winding motor, and com-
pensator in connection with machinery for clothing top rollers for textile machinery
with paper substantially as described and illustrated.
Second. The use of regulating screws in the screwed mandrels for applying and
adjusting tension in unwinding reels of paper used for clothing top rollers for
textile machinery substantially as described and illustrated.
Third. The combination of the various parts forming a machine for clothing top
rollers for textile machinery with paper tape as shewn and described.
