Improvements in Apparatus for use in the Pasting, Measuring, and
Cutting of Cloth or Material for Covering Spinning Machine
Rollers, and for other purposes.
We JOSEPH STANDRING DRONSFIELD and JAMES DRONSFIELD of the firm
of Dronsfield Brothers Limited, 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:-
Our invention relates principally to the preparation of the roller cloths which are
used in the covering of rollers employed in the preparation and spinning of textile
materials. A former invention for which Letters Patent number 11567 of the
year 1890 have been granted to one of us namely the said Joseph Standring
Dronsfield related to the preparation of these roller cloths. In the former apparatus
gripping parts were used to draw forward the cloth which was coated with paste
supplied to a pasting box situated behind the cutting knife. In our invention we
feed the cloth forward below the cutting knife instead of drawing it forward.
We
are thereby enabled to have a table to receive the cloth in front of the knife such
table being free from slides and other encumbrances. To feed forward the cloth
we employ a modification of the feed apparatus which is described and illustrated
in the Specification of the invention for which Letters Patent number 1858 of the
year 1889 have been granted to the said Joseph Standring Dronsfield. We employ
a measuring roller and an arc with stops for the handle or lever but the roller
feeds the cloth forward by contact with the back of the cloth. To enable the
roller to act upon the cloth we cover the roller with card clothing or provide it
with pin points or otherwise roughen the roller so that when the roller is turned the
cloth will not slip upon the roller.
Before passing to the roller the cloth receives a coating of paste.
The paste is
contained in a rectangular box which is provided with a piston which is pressed
toward the back of the box by a load or spring acting through a shaft and lever or
through a rack and pinion. The cloth is led over the back plate of the box entering
and issuing through slots which can be regulated in length by means of sliding
plates which when adjusted are secured by means of thumb screws or by suitable
means. One half of the box or a part of the box is hinged to the other part
or is removable in order that the box may be opened to obtain easy access to
its interior for charging and cleansing purposes. The side of the box which is
the issuing side for the cloth or which is the top plate of the box is fitted to
slide toward and from the cloth and can be adjusted by means of a screw the edge
which is toward the cloth being adapted to act as a doctor to regulate the layer
of paste. By preference the knife is pressed down to cut by means of a crank
shaft or of a lever or of a lever and shaft and is returned by means of a spring or
of springs. The apparatus or modifications of the same might be adapted for use
in the pasting and cutting of material for purposes other than herein specified.

We JOSEPH STANDRING DRONSFIELD and JAMES DRONSFIELD of the firm
of Dronsfield Brothers Limited, of the Atlas Works, Oldham, in the County of

invention and in what manner the same is to be performed to be particularly

We
Our invention relates principally to the preparation of the roller cloths which
are used in the covering of rollers employed in the preparation and spinning of
textile materials. A former invention for which Letters Patent number 11567 of
the year 1890 have been granted to one of us namely the said Joseph Standring
Dronsfield related to the preparation of these roller cloths. In the former apparatus
gripping parts were used to draw forward the cloth which was coated with paste
supplied to a pasting box situated behind the cutting knife. In our invention we
feed the cloth forward below the cutting knife instead of diawing it forward.
are thereby enabled to have a table to receive the cloth in front of the knife, such
table being free from slides and other encumbrances. To feed forward the cloth
we employ a modification of the feed apparatus which is described and illustrated
in the Specification of the invention for which Letters Patent number 1858 of
the year 1889 have been granted to the said Joseph Standring Dronsfield. We
employ a measuring roller and an arc with stops for the handle or lever but the
roller feeds the cloth forward by contact with the back of the cloth. To enable
the roller to act upon the cloth we cover the roller with card clothing or provide
it with pin points or otherwise roughen the roller so that when the roller is
turned the cloth will not slip upon the roller.
Before passing to the roller the cloth receives a coating of paste. The paste is
contained in a rectangular box which is provided with a piston which is pressed
toward the back of the box by a load or spring acting through a shaft and
lever or through a rack and pinion. The cloth is led over the back plate of
the box entering and issuing through slits which can be regulated in length by
means of sliding plates which when adjusted are secured by means of thumb
screws or by suitable means. One half of the box or a part of the box is
hinged to the other part or is removable in order that the box may be opened

The
The construction of our improved measuring, pasting and cutting machine is
illustrated by the accompanying diawings
-
Of these drawings Fig. 1 represents a side elevation of the machine and Fig. 2
an end elevation of the same.
Figs. 3, 4 and 6 are detail views of parts of the pasting box.
Fig. 5 is a detail view showing the ratchet pawls which are hidden in Fig. 2 and
Fig. 7 illustrates a modification which we may make in the machine.
In the drawings certain important parts which have actions the same as or
similar to parts which appear in the drawings attached to the Specifications of the
prior inventions hereinbefore referred to are marked with corresponding letters of
reference.
In Figs. 1 and 2 a-indicated by a dotted circle in Fig. 1-is the measuring
roller, oo is the paste box, h is the hand lever for actuating the measuring roller
and d is the cutting knife. The measuring roller appears most clearly in Figs. 2

page_text: and 4. The said roller is provided with a shaft or is formed with gudgeons a¹
whereby the roller is mounted to revolve in bearings formed in or carried by the
framing B of the machine. The said roller is covered with fine wire card of an
ordinary description or with a special short toothed card which may be made
without the ordinary bends in the wires, the points of the wires constituting the
measuring periphery of the roller. The cloth to be pasted is preferably supplied
in a roll provided with a central wire or spindle which can be mounted within the
framing as indicated at c in Fig. 1. From this roll the cloth b is drawn forward to
the paste box passing below the rounded edge of a back plate e which nearly
closes the back end of the paste box. This plate appears in section in Fig. 4. The
paste box is formed in two principal parts o o' the part o being fixed to the framing
whilst the part o' is hinged to lugs o formed upon the fixed part o. The box can
be opened by raising the top o'. The piston p is attached to an arin p' which is
jointed to the upper end of a lever q which is carried by a rock shaft and this shaft
is turned by means of a loaded lever so as to press the piston toward the back end
of the box as in the aforesaid invention of 1890. When the top part o¹ is raised
the piston can be turned over out of the box so that the interior of the box is
fully exposed and can then be readily cleansed. The cover plate o of the box is
fitted to slide between vee cheeks in the manner more clearly indicated in Fig. 3,
the plate being mounted to slide toward and from the back plate e so that the front
edge of the cover plate shall always be parallel with such back plate. The said
front edge of the cover plate is bevelled as indicated in Fig. 4 or the said edge is
otherwise adapted to act as a doctor to remove superfluous paste from the cloth.
The cover plate can be adjusted nearer to or further from the back plate by means
of a screw l. The cloth passes upward in front of the back plate e to the
measuring roller.
The apparatus is adapted to operate upon cloths varying in
width. Without some special provision the paste would be forced out of the ends
of the slits through which the cloth enters and leaves the paste box when cloths
narrower than the lengths of the slits were being treated. To prevent this escape
of paste adjustable closure plates mm are used. These plates appear in Figs. 1, 2,
4 and 6, the latter being a plan view of part of the back end of the lower part o
of the paste box. Each plate is equal in breadth to the depth of the box and is
fitted to slide between the bottom of the box and the cover plate o³ and between
the back plate e and the flange of formed on the box o at right angles with the
same. The plates are nicely fitted so that little or no paste will be liable to
escape between the plates and the surfaces with which they are in contact. The
plates are fitted to be slid toward and from the centre of the paste box, and are
intended to be adjusted so that there shall be a space between the plate ends
sufficient for the passage of the cloth. When adjusted the plates are secured by
means of set screws n n. When properly adjusted these plates leave slits only
long enough to permit of the free passage of the cloth. From the paste box the
cloth passes to the measuring roller a. Upon the shaft of this roller is fixed a
spur wheel which gears with a wheel g which is loosely mounted upon a ɛtud g¹,
the hand lever h being also loosely mounted upon this stud. A ratchet wheel ris
attached to the spur wheel g and upon a stud fixed to the hand lever are mounted
a series of pawlss which vary in length in order that the pawls may be capable of
rotating the ratchet wheel to an extent including a fraction of the distance from
one tooth to the next as is well understood. These pawls appear in Fig. 5. By
using a ratchet wheel of fine pitch I can obtain a sufficient degree of uniformity
in the movements of the measuring roller. The movements of the hand lever are
limited by fixed and adjustable stops, the adjustable stop j being adapted to be
fixed in any required position upon a slotted arc k as in the former invention of
the year 1889. When the hand lever is moved back against the fixed stop at i the
gearing remains at rest. When the handle is moved forward into contact with the
adjustable stop the ratchet wheel is turned by one of the pawls whereby motion
is communicated through the gearing gf to the measuring roller which is revolved
in the direction indicated by the arrow in Fig. 4 to an extent determined by the

page_text: position of the stop j and a measured quantity of cloth is thereby passed forward
along the table t. This table may consist of a renewable piece of wood. The
cloth as it is fed forward passes below the cutting edge of the knife d. This knife
is secured to a sliding carriage which is operated by a crank shaft u upon which is
fixed a hand lever v. When this lever is brought down upon an adjustable stop-
indicated by the dotted lines at w in Fig. 1,-the knife is forced down and the cloth
is severed. As the method of mounting and actuating the knife carriage and
knife is similar to what is set forth with reference to the cutting knife in the
Specification of the aforesaid invention of the year 1890 it has not been considered
necessary to enter more fully into a description of the details of the said parts.
When the machine is in operation a length of cloth coated with paste is drawn
forward through the paste box by moving the hand lever / from i to j and the end
of the cloth is passed on to the table a measured distance beyond the line of cut of
the knife. The hand lever is then put back to the stop i and the hand lever o is
brought down upon the stop w whereby the measured length of cloth is severed.
The thickness of the coating of paste is regulated by turning the screw l. Fig. 7
illustrates a modification which we may make in the apparatus. In the machine
as so far described the measuring roller has to draw the cloth through the paste
box and it may be considered that the resistance offered by the cloth may cause
a little slipping of the cloth upon the roller whereby the measurement may be
rendered irregular. To obviate this possible defect is the object of the modification.
In addition to the measuring roller a a drawing roller x might be used, the latter
roller revolving in unison with the measuring roller and at about the same surface
speed or if found to be advisable at a slightly increased speed. The cloth would
extend loosely from one roller to the other so that the measuring roller would be
freed from the strain of passing forward the cloth. The additional roller .r might
be loose upon its shaft and be connected therewith by means of a ratchet wheel
and pawl so that the roller could be turned independently of the measuring roller
to slacken the cloth between the two rollers. If considered to be advisable a
roller might be applied in front of the knife but below the table to aid in passing
forward the cloth.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination of parts constructed and adapted to act substantially as and
for the purpose set forth and indicated.
2. The paste box formed in two parts, one part hinged to the other substantially
as and for the purpose set forth and indicated.
3. In a paste box for the purpose set forth the cover plate mounted to slide
adjustably so as to act to regulate the coating of paste substantially as set forth
and indicated.
4. The adjustable plates or sliding shutters m m in combination with a paste box
for the purpose set forth.
5. In a machine for pasting and measuring cloth or material drawing or passing
the cloth over or in front of a plate which constitutes the back or end plate of a
rectangular box to contain paste which is forced toward the cloth or material by a
piston substantially as set forth and indicated.
6. In a machine for pasting and measuring cloth or material a measuring roller
having a surface adapted to take hold of the back of the pasted cloth or material
and to draw or pass the cloth or material forward in combination with means for
turning the roller to a regulatable determined extent and for severing the cloth
nto lengths substantially as set forth and indicated.
