PROVISIONAL SPECIFICATION.
An Apparatus for use in the Pasting, Measuring, and Cutting of
Roller Cloths.
I JOSEPH STANDRING DRONSFIELD of the firm of Dronsfield Brothers of
the Atlas Works Oldham in the County of Lancaster Card Grinding Machine
Makers do hereby declare the nature of this invention to be as follows:-
My invention relates to the preparation of the roller cloths which are used in
the covering of rollers employed in the preparation and spinning of textile materials.
Previously to my invention my said firm has made machines for pasting the strips
of cloth such strips having been cut up into measured lengths by hand. The object
of my present invention is to facilitate the cutting of the cloth into measured
lengths which shall be true in form and shall be of uniform size. In the apparatus
which I have designed for the purpose the strip of cloth passes between adjustable
cheeks over a table and below a doctor the paste being supplied to the space partly
enclosed by the said cheeks and doctor as in the apparatus made by my firm as
aforesaid. To press the paste well into the corner behind the doctor I apply a
pusher plate which is connected with arms upon a rock shaft which is provided
with a loaded lever or I otherwise so mount the said pusher as that it shall be
caused to press the paste forward toward the doctor with a yielding pressure. The
pasted cloth passes from the doctor below the edge of a knife which is adjustably
attached to a knife carriage which is guided to move toward and from a changeable
bed of hard wood or other suitable material over which the cloth passes. The
knife carriage is slid to and fro by means of a hand lever which acts upon the knife
carriage through a crank shaft or a rocking shaft which is formed or provided
with crank or lever arms or with cams or excentrics to act upon the carriage so
as to force the knife through the cloth the return movement of the knife carriage
being effected by the direct action of the said hand lever or by means of a spring
or load. I prefer to limit by means of an adjustable stop the movement of the
said hand lever or of the knife carriage in the direction to effect the cut so that the
knife edge shall not be forced too deeply into the knife bed. After the knife has
retired a grip clamp is pushed toward the cut edge of the strip of cloth. This clamp
is guided to move in a straight line which is at right angles to the said cut edge the
to and fro movements of the clamp being limited by stops. The extent of the
backward movement of the clamp is indicated by a scale so that any required
movement of the clamp may be obtained such movement corresponding to the

pushed forward the cut edge of the cloth passes between the two jaws of the clamp
and one of the jaws which is movable is forced upon the cloth by means of a cam
lever or of a screw spring or load. To ensure the clamp taking a secure hold one
or both of the jaws may be provided with pins or teeth or may be suitably adapted
to take hold of the cloths. When the clamp is pushed back to the measuring stop
the strip of cloth is drawn forward to a measured extent and when the knife is
brought down the required length is severed from the strip. It may be necessary
to slightly raise the front edge of the strip of cloth after the cut to permit the
lower jaw of the clamp to pass under. For this purpose I may employ a spring
pusher or a plate or bar carried by a lever which tends to raise such plate or bar.

An Apparatus for use in the Pasting, Measuring, and Cutting of
Roller Cloths.
I JOSEPH STANDRING DRONSFIELD of the firm of Dronsfield Brothers of
the Atlas Works Oldham in the County of Lancaster Card Grinding Machine
Makers 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 and accompanying drawings :-
-
My invention relates to the preparation of roller cloths which are used in the
covering of rollers employed in the preparation and spinning of textile materials.
Previously to my invention my said firm has made machines for pasting the strips
of cloth such strips having been cut up into measured lengths by hand. The object
of my present invention is to facilitate the cutting of the cloth into measured
lengths which shall be true in form and shall be of uniform size. In the apparatus
which I have designed for the purpose the strip of cloth passes between adjustable
cheeks over a table and below a doctor the paste being supplied to the space partly
enclosed by the said cheeks and doctor as in the apparatus made by my firm as
aforesaid. To press the paste well into the corner behind the doctor I apply
pusher which is connected with arms upon a rock shaft which is provided with a
loaded lever or I otherwise so mount the said pusher as that it shall be caused to
press the paste forward toward the doctor with a yielding pressure. The pasted
cloth passes from the doctor below the edge of a knife which is adjustably attached
to a knife carriage which is guided to move toward an from a changeable bed of
hard wood or other suitable material over which the cloth passes. When the knife
has retired after making a cut a grip clamp is pushed toward the cut edge of the
strip of cloth.
This clamp is guided to move in a straight line which is at right
angles to the said cut edge the to and fro movements of the clamp being limited
by stops. The extent of the backward movement of the clamp is indicated by a
scale so that any required length of forward movement of the cloth may be obtained
such movement corresponding to the length of the piece of cloth which is to be
severed at each cut. As the clamp is pushed forward the cut edge of the cloth
passes between the two jaws and one of the jaws which is movable is forced upon
the cloth by means of a cam lever or of a screw spring or load. When the clamp
is pushed back to the measuring stop the strip of cloth is drawn forward to a
measured extent and when the knife is brought down the required length is severed
from the strip..
In order that my invention may be clearly understood I will describe the same
more fully with reference to the accompanying drawings. In the said drawings
Fig. 1 represents a side elevation and Fig. 2 a plan of my measuring pasting and
cutting machine. Fig. 3 is a vertical sectional view of part of Fig. 1.
دو
In the said figs. or in Fig. 3 a is a bed which carries the parts of the machine b
represents cloth passing into the machine c is the doctor d is the knife and e is the
measuring slide and clamp. To the bed a is bolted a bracket f which is formed
and provided with " vec guides and is planed to receive a sliding knife
carriage g to which is secured the knife d. In bearings formed in lugs which
are cast, upon the bracket fa shaft is mounted and upon each end of this
shaft is fixed a short lever which carries a stud or crank pin h. Each stud
works in one of two jaws d' which are formed one at each end of the knife
carriage. It will be seen that when the shaft is turned in its bearings the knife
carriage will be caused to slide up or down. The shaft his acted upon through a
hand lever i which is provided with a loaded arm which tends to raise the said
hand lever and thereby to withdraw the knife upward.
The knife can be adjusted upon its carriage by means of set screws j so that the
cutting edge of the knife shall be parallel with the knife bed. The said knife

page_text: bed k consists of a strip of hard wood tightly fixed in a recess in the bed a. When
the hand lever i is brought down the knife carriage is pushed down until the cutting
edge of the knife bears upon the bed k. When the knife is fully down the outer
end of the hand lever bears upon the head of an adjustable screw / which pre-
vents any further movement of the lever. By turning this screw in one direction
or the other the extent of penetration of the knife into the bed k can be increased
or regulated. When the said bed has become too deeply indented it may be
reversed or replaced with a new bed. The back of the bracket f is planed to
receive a doctor carriage m which is secured to the bracket by means of screws which
permit of the carriage being moved toward and from the bed a the parallelism of
the carriage being retained by means of planed cheeks or projecting ribs upon the
bracket. To this carriage m is secured the doctor c and below the lower edge of
this doctor the cloth passes as it is drawn forward. The distance of the doctor
from the cloth or the degree of closeness of contact between the doctor and the
cloth can be regulated to a nicety by turning a regulating screw n. Two cheeks oo
are mounted to slide upon the bed a. The opposed faces of these cheeks are
vertical and parallel one with the other and the ends which are toward the
doctor are inclined and shaped to fit against the doctor. The two cheeks are
attached to nuts o' which are fitted to slide in a planed slot in the bed and engage
with a right and left hand screw o². By turning this screw by means of the
head of the distance between the two cheeks may be regulated to suit the width
of the strip of cloth which is to be cut up the cheeks being adjusted so that the
cloth will just pass easily between them. Resting upon the cloth is a pusher
plate p which is of such a length as to slide easily between the two cheeks and is
connected with a lever or with a pair of levers upon the shaft q' which is mounted
to turn in bearings. Upon this shaft is fixed a weighted lever q which tends to
force the pusher plate toward the doctor. Upon the two cheeks a loose metal
plate ŕ rests. It will be seen that the doctor, the two checks, the plate r and the
pusher plate formn a box or receptacle having the cloth for its bottom. This box
is filled with paste which is pushed forward toward the doctor by the plate p. The
measuring slide e is mounted to slide in a straight line in planed ways toward and
from the knife carriage the direction of such sliding movement being in the
example at right angles to the line of cut of the knife and parallel with the inner
faces of the checks o. To the front end of the said slide is fixed a thin plate e¹
which projects from the slide in order that the said plate may pass over the knife
bed when the slide is pushed forward. Hinged to the slide e is a clamping jaw s
which is furnished at its front edge or lip s with a row of teeth. The jaws is
raised from the plate by means of a spring but can be closed tightly down upon the
plate e by means of a cam lever t. When the slide e is pushed forward toward
the bracket the front end of the slide passes between two projecting ribs a¹ which
keep the bed in place so that the jaws se can pass below the knife. To enable
the lower jawel to pass below the cloth the latter is lifted away from the bed k by
means of a rising lifting bar u which is carried by one end of a lever v v¹ which is
mounted to turn upon a fulcrum o². The said lever is within the bed but is
indicated by dotted lines in Figs. 1 and 2. The longer arm of this lever
is heavier than the shorter arm so that there is a tendency for the lifting bar u to
rise above the surface of the bed the amount of projection above such surface
being regulated by means of a screw. The movement of the slide e is limited
in both directions in the forward direction by the bed and in the backward
direction by an adjustable stop w. This stop is mounted to slide in the same slot
as the part e and is connected with the nut of the screw whereby the stop can be
adjusted in position with great nicety. The position of the stop determines the
length of each piece of cloth which is severed from the riband such length being
indicated upon a scale of inches and parts of an inch as seen in Fig. 2. By setting
the index on the stop to any desired indication of length pieces of cloth of such
length can be cut with great accuracy. The stop is secured in its adjusted position
by means of a nut and bolt y. The method of using the machine will be readily

page_text: understood. The slide e being pushed forward the lower jaw e¹ passes below the
cloth which is lifted as in Fig. 3 and the clamping levert is turned down so as to
close the upper jaw tightly upon which carries a coating of paste of a thickness
the cloth. The slide is then drawn back to the
stop w drawing forward the
regulated by the doctor. The lever i is then brought down upon the support
whereby the knife is caused to sever the measured length of cloth. The knife
carriage is arranged to slide in a direction which makes less than a right angle with
the bed partly for the reason that the cloth is thereby cut with beveled edges
which facilitate the making of a good joint when the cloth is applied to the roller.
If preferred the parts might be arranged to give a diagonal cut across the width
of the riband of cloth. I do not confine myself to the screw adjustment of the
stop w nor to the screw adjustment of the cheeks o nor to the precise details of
the apparatus.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The combination of parts constituting the apparatus substantially as and for
the purpose set forth and indicated.
2. The apparatus for pasting measuring and cutting roller cloth consisting
principally of a clamp or cloth gripper mounted to slide to and fro an adjustable
stop to regulate the extent of movement of such clamp a knife secured to a carriage
guided to move toward and from the knife bed and actuated by means of a lever
or shaft combined with means for supplying paste to the cloth substantially as set
forth and indicated.
