PROVISIONAL SPECIFICATION.
Improvements in or applicable to Machines for Finishing Textile
Fabrics.
We, CHARLES EDMESTON of the Firm of Archibald Edmeston & Sons, of
Cannon Street Works, Salford, in the County of Lancaster, Millwrights_and
Engineers, and WILLIAM BOSTOCK PARKINSON, of 1 Kersall Terrace, Whit
Lane, Pendleton, Salford, in the said county, Foreman Finisher, do hereby declare
the nature of the said invention, to be as follows :-
Our improvements are applicable more especially to machines for stretching
and finishing textile fabrics, similar to the machine described in the Complete
Specification of Letters Patent No. 4480 of 1892 granted to Charles Edmeston
(one of the present Applicants) and Alfred Edmeston.
"
Our improvements relate to arrangements for "breaking down" and "softening
textile cloth which has been treated with stiffening materials so as to make both
the body of the fabrics and their selvedges or margins of the same uniform
character "feel" or softness, and our invention relates more especially to arrange-
ments for operating more effectively upon the margins or selvedges of the fabrics
to be treated.
The cloth to be operated upon is taken over the edge of one square bar and
under another, these two square bars have their ends secured in and carried by
cross bars, thus forming a frame, the cross bars of which have each a pivot which
rest in bearings in the framing of the machine, so that these two square bars can
be partly rotated on the pivots of the frame and held in any required position by
suitable mechanism in order to put more or less friction and tension upon the
passing cloth.
The pivotted cross bars have also two additional arms at about a right angle
more or less to the arms or cross bars for the square bars, in which additional arms,
slots or other arrangements are formed for sliding bearings for two shafts extending
from the arm of one cross bar to the other, and the bearings for these shafts can
be adjusted by screws or other means to move nearer to and further from each
other.
Upon these shafts, at each end there is a drum or roller the periphery of each of
which is corrugated, the corrugations being in the direction of the axis of the drum
or roller, or the corrugations are in a direction of and somewhat similar to the
teeth of a spur wheel, but of less depth and a different shape. The corrugation of
the drums or rollers on one shaft fit into those on the other shaft when the drums
or rollers on two shafts are brought together.
The corrugated drums or rollers can be adjusted and secured in any required
position in the lengthway of the shafts to operate upon the desired parts of the.
fabric which passes over and under the edges of the square bars and between the
corrugated drums or rollers which come between the two square bars.
Corrugated drums or rollers extending the full width of the fabric to be treated
may be used in some cases if desired.
Dated this Fifteenth day of December 1893.

Improvements in or applicable to Machines for Finishing Textile
Fabrics.
We, CHARLES EDMESTON, of the Firm of Archibald Edmeston & Sons, of
Cannon Street Works, Salford, in the County of Lancaster, Millwrights and
Engineers, and WILLIAM BOSTOCK PARKINSON, of 1 Kersall Terrace, Whit
Lane, Pendleton, Salford, in the said county, Foreman Finisher, 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 :-
Our improvements are applicable more especially to machines for stretching
and finishing textile fabrics, similar to the machine described in the Complete
Specification of Letters Patent No. 4480 of 1892 granted to Charles Edmeston
(one of the present Applicants) and Alfred Edmeston.
"
Our improvements relate to arrangements for "breaking.down" and "softening'
textile cloth which has been treated with stiffening materials so as to make both
the body of the fabrics and their selvedges or margins of the same uniform
character "feel" or softness, and our invention relates more especially to arrange-
ments for operating more effectively upon the margins or selvedges of the fabrics
to be treated.
The cloth to be operated upon is taken over the edge of one square bar and
under another, these two square bars have their ends secured in and carried by
cross bars, thus forming a frame, the cross bars of which have each a pivot which
rest in bearings in the framing of the machine, so that these two square bars can
be partly rotated on the pivots of the frame and held in any required position by
suitable mechanism in order to put more or less friction and tension upon the
passing cloth.
The pivotted cross bars have also two additional arms at about a right angle
more or less to the arms or cross bars for the square bars, in which additional arms,
slots or other arrangements are formed for sliding bearings for two shafts extending
from the arm of one cross bar to the other, and the bearings for these shafts can
be adjusted by screws or other means to move nearer to and further from each
other.
Upon these shafts at each end there is a drum or roller, the periphery of each of
which is corrugated, the corrugations being in the direction of the axis of the drum
or roller, or the corrugations are in a direction of and somewhat similar to the
teeth of a spur wheel, but of less depth and a different shape. The corrugation of
the drums or rollers on one shaft fit into those on the other shaft when the drums
or rollers on two shafts are brought together.
The corrugated drums or rollers can be adjusted and secured in any required
position in the lengthway of the shafts to operate upon the desired parts of the
fabric which passes over and under the edges of the square bars and between the
corrugated drums or rollers which come between the two square bars.
Corrugated drums or rollers extending the full width of the fabric to be treated
may be used in some cases if desired.
Fig. 1, is an end elevation and Fig. 2, a longitudinal section of the mechanism
forming the subject of our invention.
Fig. 1, is a view similar to Fig. 4, of the drawings of the Complete Specification
of the aforesaid Letters Patent No. 4480 of 1892.
a, is a stand or bracket carrying the rollers marked e and e', in the said Complete
Spécification, the position of which rollers is also shown in Figs. 1 and 2 of the
drawings of the aforesaid Complete Specification.

page_text: The mechanism forming the subject of our invention operates upon the fabric
being treated before it arrives at the "belt stretching pulleys" as described in the
aforesaid Complete Specification.
, is one of the cross heads (one only shown in Fig. 2); ", the trunnion axis;
the two square bars; f³, hand wheel secured on one of the trunnions at
one end.
'
The above parts referred to by letters are the same or modifications, as hereinafter
described of the parts referred to by the same letters of reference in the aforesaid
Complete Specification.
The pivots, of the rollers e and e', rotate in bush bearings e³, which fit holes
for them in the stand a, which bushes when in position can be secured by a set
screw, (one at each end) screwing through the stand, the point of the set screw
coming against the bush bearing.
The slot or hole a', in the stand a, for the roller e, is formed so that the bush e³,
may be either placed in the position in which it is shown in Fig. 1, or in the hole a¹,
and then be secured by a set screw e.
The roller e, as shown, is in a position suitable when the fabric passes to it on or
below the line, and when the bush is in the other hole a', the roller e, is then in
the position to suit the fabric coming in the line, or from above that line.
There is a slot across the bush e, and a hole across the pivot of the rollers e
and e, for a pin e, to pass through when desired.
When the pin e, is not used the roller e or e¹, can freely rotate, but in some
cases the fabric is required to pass over the surface of the roller when it thus acts
as a guide and to put friction upon the passing fabric, and it is then when the
pin e, is used to prevent the roller from revolving.
Both rollers and e', may thus be prevented from revolving by a pin e³,
passing through the hole across each pivote, and through the slot in the bush
bearing e³.
The two square bars f³, have a pivot fx, at each end which fit holes in the cross
head, and each pivot is secured in the hole in the cross head by a set or thumb
screw, the point of which comes against a key shaped piece of metal f*, fitting a
slot in the cross head, the piece of metal being concave on the side-against the pivot
to fit its cylindrical surface.
By this arrangement the bars fa, can be turned upon their pivots and secured at
any desired angle.
One corner of each bar f, has a groove in it from end to end in which a thin
slip of steel, is inserted, and held at each end of the bar "", by a hoop similar to
the hoops, secured by the set screws f, for the hoops described in the aforesaid
Complete Specification.
But the steel edges f*, according to the present invention are not the inclined
slips of steel at each end of each square bar f, described in the aforesaid
Specification, but they are steel edges extending the full length of the edge of
the square bars ƒ³, and these steel edges operate upon the entire width of the
fabric.
The cross heads f, according to our invention (one at each end of the bars) are
different in shape to those shewn in the aforesaid Complete Specification, as they
are made with parts in which slots g', are formed radially from and upon opposite
sides of the axis f¹.
These slots g, are for the ends of two shafts which pass through the slots.
There is a collar g³, upon each shaft g, secured from moving endways upon the
shaft by a pin passing through a hole in the collar and shaft.
The outer end of each shaft g, is reduced and screw threaded for a screw nut 9³,
which and by means of a washer is screwed up tightly when the shaft 9, is adjusted,
drawing the inside of the collar g³, upon the shaft against one side of the cross
head f
A thumb or set screw 9, is fitted in a hole in the cross head, in a line with the
lengthway of the slot g¹, in the cross head for the shaft and this screw g*, screws

page_text: through a screw tapped hole passing through the shaft g, and its inner point has a
footstep bearing in a hole in the inner end of the slot g'.
There is a groove round the thumb screw 9, which the point of a set screw g",
enters that screws through a tapped hole in the side of the cross head and thus
prevents the thumb screw g', from moving outwards endways while allowing it to
be rotated.
in the slots
This arrangement of screws for adjusting and securing the shaft 9,
in the cross head f, is used at each end of each shaft g, there being a cross head at
each end.
It will be understood that the two shafts g, arranged as above described do not
rotate upon their axes.
Upon each shaft 9, there are two pulleys or drums, having grooves and
projections upon their peripheries in planes at a right angle to the axis of the
shaft g, forming corrugations the projections on one drum h, on one shaft g, fit the
hollows of the other drum h, on the other shaft g. These drums thus work in pairs,
and there is a pair of these drums on each end of the shafts g, to act upon the cloth
at or near its selvedges, which passes between the drums h.
These drums h, have a bush ', of brass at each end and they can rotate freely
upon the shafts y, and they are rotated by the friction and drag of the fabric
passing between them.
The drums /, can be slided upon the shafts g, to any required position and then
are secured by collars h³, at each end of the lower drum h, by thumb or set
screws ³, on the shaft g, the lower drum is prevented from moving endways and
the lower drum of each pair being thus fixed, the upper drum h, is kept in
position by the projections of one drum entering the hollows or grooves of the
other drum.
The square bars f³, and shafts g, being carried by the cross heads f, they can be
moved into any required position by means of the hand wheelf, and may then be
secured by a thumb or set screw, acting upon a block of metal" the underside
of which fits the convex surface of the axis f, where they come together.
Instead of the drums h, as on the left of Fig. 2, at both ends of the shafts g,
drums, on both ends of the shafts g, as shown on the right side of Fig. 2, may be
used, having teeth similar to spur toothed wheels except that the top and bottom of
each tooth is rounded.
The end of each spur drum h, has an ordinary spur toothed wheel ³, secured to
it, the spur wheel of one drum of one pair of drums gearing with the spur wheel of
the other drum, the spur wheels being equal wheels.
The drums, and wheels h³, are rotated upon the shafts g, by the drag and
friction of the cloth passing between them, and the spur wheels h³, act to prevent
the sides of the spur rounded teeth of the drum h, from pinching the cloth between
them, which thus passes over and between them and is bent to their corrugations but
without being pinched between them.
When spur toothed drums, are used, both drums are prevented by collars h³,
on the shafts g, from moving end ways when placed in the position on the shafts g,
in which they have to work.
If desired the ends of the shafts g, may be placed in step bearings that can slide
in slots in the cross heads f, and be acted upon by adjusting screws to regulate the
distance of the shafts from each other.
The shafts g, in this case will rotate on their axes, and the drums h or h³, will be
secured to the shafts and will rotate with them.
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 use of drums h or h', or their equivalents, substantially as and for the
purpose hereinbefore described and illustrated by the drawings.
