OR
Our invention has reference to machinery for winding paper into rolls. In a
machine for this purpose according to our invention the desired length of paper is
first wound upon a spindle as well understood, then by throwing a clutch out of
gear and applying brakes the machine is stopped, the wound up paper is severed
from the unwound, and the roll of paper removed from the spindle is thereupon
received by a supporting contrivance, which may consist of curved brackets, and
there retained whilst the operator secures the free end of the unwound paper to or
on the spindle, and puts the machine in operation to wind up another length of
paper into a roll. Whilst this is being done by the machine the operator "knocks
up" the ends of the previously wound roll between a stationary abutment or
surface and a moveable pusher which is operated by a lever moved by a spring in
one direction and by the operator's hand in the reverse direction. When a roll of
paper has been "knocked up" by the rapid movement of the lever by the spring
the operator moves back the lever which withdraws the pusher in opposition to
the spring and the lever is retained in the position to which it has thus been moved
by a suitable catch. On the operator releasing the lever from this catch at the
proper time the spring operates the pusher to "knock up" the ends of another roll
of paper as above explained. The registering roller of the machine and the shaft
froin which the winding spindle is driven through friction gear are provided each with

page_text: a brake, these two brakes are operated by the clutch lever whereby the machine
is put in and out of gear with the driving pulley. Now according to our invention
this lever works a curved block that operates a weighted lever of the first order
that is moved in a vertical plane. At the one end this lever is connected with the
brake for the registering roller, in such a way that it raises that brake when the
machine is started, and at. the other end it carries the brake for the friction pulley,
which brake is lowered at or about the same time that the other brake is raised,
the two brakes are thus removed respectively from the roller and pulley slightly
before the starting of the machine. The brake block for the registering roller is
arranged to have a certain amount of play in relation to the lever that raises it
from the roller so as to be self adjusting, the retarding action of the block being
due to its weight supplemented by an additional weight or a spring. The arrange-
ment is such that the action of each brake against the surface it is designed to
retard shall be uniform or nearly so, notwithstanding any unequal wear of the two
brake blocks. On the shaft or spindle of the registering roller is fixed a worn
actuating a worm wheel which carries a stud. This stud comes in contact with a
loose crank which carries a stud that comes in contact with the lever mentioned
above causing the friction clutch to be thrown out and the brakes to be put on as
previously described, thus stopping the machine when the required length of paper-
has been rolled.

Patent Office on the 12th May 1883.
GEORGE WILLIAM OSBORN and DOCTOR WALSH YATES, both of King's Road
Chelsea, in the County of Middlesex, IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR WINDING PAPER INTO ROLLS.
Our invention has reference to machinery for winding paper into rolls. In a
machine for this purpose according to our invention the desired length of paper is
first wound upon a spindle as well understood, then by throwing a clutch out of
gear and applying brakes the machine is stopped, the wound up paper is severed
from the unwound and the roll of paper which is removed from the spindle, is
thereupon received by a supporting contrivance, which may consist of curved
brackets and there retained whilst the operator secures the free end of the
unwound paper to or on the spindle and puts the machine in operation to wind up
another length of paper into a roll. Whilst this is being done by the machine the
operator "knocks up" the ends of the previously wound roll between a stationary
abutment or surface and a movable pusher which is operated by a lever moved by
a spring in one direction and by the operator's hand in the reverse direction.
When a roll of paper has been knocked up by the rapid movement of the lever by
the spring the operator moves back the lever which withdraws the pusher in
opposition to the spring and the lever is retained in the position to which it has
thus been moved by a suitable catch. On the operator releasing the lever from
this catch at the proper time the spring operates the pusher to "knock up" the
ends of another roll of paper as above explained.
The registering roller of the machine and the shaft from which the winding
spindle is driven through friction gear are provided each with a brake; these two
brakes are operated by the clutch lever whereby the machine is put in and out of
gear with the driving pulley. Now according to our invention this lever works
a curved block that operates a weighted lever of the first order that is moved in a
vertical plane. At the one end this lever is connected with the brake for the
registering roller in such a way that it raises that brake when the machine is
started and at the other end it carries the brake for the friction pulley which brake
is lowered at or about the same time that the other brake is raised,-the two
brakes are thus removed respectively from the roller and pulley slightly before the
starting of the machine. The brake block for the registering roller is arranged to
have a certain amount of play in relation to the lever that raises it from the
roller so as to be self adjusting, the retarding action of the block being due to its
weight supplemented by an additional weight or a spring. The arrangement is
such that the action of each brake against the surface it is designed to retard shall
be uniform or nearly so; notwithstanding any unequal wear of the two brake
blocks. On the shaft or spindle of the registering roller is fixed a worm actuating
a worm wheel which carries a stud. This stud comes in contact with a loose crank
which carries a stud that comes in contact with the lever mentioned above causing
the friction clutch to be thrown out and the brakes to be put on as previously
described thus stopping the machine when the required length of paper has been
rolled.
In the accompanying sheet of drawings is illustrated a machine for winding
paper into rolls according to our invention, Fig. 1 being a side elevation, Fig. 2
a plan, and Fig 3 an end elevation. The same letters are used in the several figures
to distinguish like parts.

page_text: A is a split spindle upon which the paper is wound. The split spindle passes as
well understood through a hollow spindle O in bearings M' a projection of the split
spindle entering a notch in the spindle O at O' so that when O is rotated as
hereinafter explained A will rotate with it. B is a lever att iched to a bracket C
by means of a stud pin D. One arm of this lever carries a stud pin E for actuating
a friction clutch F and the other arm has connected to it a curved block G for
operating the brake lever H. The male cone of the friction clutch F is fixed upon
the spindle I while the pulley K which constitutes the female cone is loose upon
the spindle.
The friction pulley L is also fixed to the spindle I. b' is a beut catch
plate (see Fig. 4 which is a section taken through 1-1 Fig. 2) Against the part b
of this catch plate the lever B is pressed by the spring T when the friction clutch F
is in gear but when the end of the lever B is depressed by the crank pin Z the
spring T forces the lever into the position shown by dotted lines in Figs. 2 and 4,
thus putting the clutch out of gear. Attached to the bracket C by means of the
stud P is the bifurcated lever M carying the bearings M' which support the hollow
spindle whereon is fixed the friction pulley N. The requisite pressure between
the friction pulleys N and L is maintained by means of the spring c' acting
-through levers d' and M and link e'.
Qshews in dotted lines a wound roll of paper lying upon the brackets R. and
between the knocking up discs S S'. U is a registering roller having fixed to one
end of its spindle the worm V which gears with the worm wheel W. On the
axis a' of the worm wheel W is fitted loosely the crank Y carrying the pin Z and
in the worm wheel W is fixed the crank pin X The roller U is provided with a
brake factuated by the lever-H-through-a-projecting finger g¹ (see detached plan
view Fig. 5) The brake f¹ comprises a curved block shewn clearly-in-big-l-and-
attached to or formed with a stem the upper part of which is provided with a
weight or load that presses the block against the roller U when not raised out of
contact therewith by the lever H. is a guide roller, a guide bar, and
-guide-board over which the paper travels from the source of supply
a
We will now describe the knocking up apparatus-which comprises a stationary
disc S and a movable disc S. operated by a lever m'. is a headstock having a
long slot so formed that when the spring lever m¹ is drawn back it can rest in the
recessed portion n' of the slot. In this position the knocking up disc S is drawn
back against the headstock . 2 is a lever pivotted at p to the headstock. By
pushing or striking the head o' of this lever its other end is caused to release the
lever m' from the recess n' and by the action of the spring m³ the knocking up
disc S is caused to strike the roll of paper previously dropped into position
between S and S as will be presently described. The mode of operating the
machine is as follows:-
The lever B being in the position shewn in dotted lines in Fig. 2 the registering
roller U is turned to the zero position and the curved block G (whose forin is
indicated separately in Fig. 6) being withdrawn from under the brake lever H
allows the brakes to be applied by the operation of the weighted lever H to the
pulley L and the roller U."
The paper to be rolled is then drawn over the guide j' and bar i under the
roller U and over the roller h' to the split spindle A between the parts of
which it is inserted before the end of the spindle is put into the hole in the
headstock ¹
The lever B is then returned to the position indicated in full in Fig. 2 thus
putting the friction clutch F into gear and taking the brakes off roller U and
friction pulley L.
In this position the lever B is retained by 6' as already explained. When the
roller U has made the number of revolutions corresponding to the length of paper
required to form a roll the crank pin Z is by the action of the crank pin X caused
to press down and release from 6 the end of the lever B which is then pushed by
means of the spring T into the position shown by dotted lines in Fig. 4.
The curved block G being now withdrawn by the lover B allows the brakes to

page_text: •
operate again upon the roller U and pulley L and thus bring the machine to
rest.
The crank Y being loose upon the axis a' falis past the end of the
lever B.
The roll of paper wound on A is severed from the remainder, the spindle A is
withdrawn and the roll of paper is dropped upon the brackets R between the
knocking up discs SS' to be knocked up. The split spindlo A is returned
through O and attached to the free end of the unrolled paper ready for winding up
another roll and whilst this is being done the head o' of the lever 2 is pushed or
struck and releases the spring lever m' from the recess n' thereby actunting the
knocking up disc S as already described. The machine is driven by a belt passing
over K.
Having described the nature of our said invention and the manner of carrying
it into practical effect we would have it understood that what we consider to be
novel and original and therefore claim as the invention secured to us under the
bereinbefore in part recited Letters Patent is :-
1. The arrangement whereby whilst one roll of paper is being formed or wound
upon the spinule A the ends or edges of another roll previously formed or
wound upon that spindle can be "knocked up" or straightened substantially as
described.
.
2. The arrangement described whereby practically simultaneous action of the
brakes is ensured notwithstanding any unequal wear of the two brake blocks."
3. In combination with the brakes referred to in claim 2 the arrangement
described for operating the same.
