-
PROVISIONAL ŠPECÍFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 21st April 1875.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
FOR TENTERING, STRAIGHTENING, DRYING, AND FINISHING CLOTH AND OTHER
FABRICS," to be as follows:-
This Invention
so far as it relates to the tentering and straightening

page_text: of cloth and other fabrics, includes various novel constructions and
combinations of devices to adapt the Invention to different descriptions
and qualities of fabrics.
One feature of the Invention relating to oblique or diverging selvedge
carrying and feeding devices consists in a tentering and straightening
apparatus in which there is combined with oblique or diverging and
revolving selvedge carriers or wheels a novel arrangement of endless
belts, bands, or chains made to move in common with said wheels for
holding between them and the wheels the selvedges of the fabric to be
tentered and straightened, pulleys for guiding said belts, bands, or
chains, and a delivery roll for the fabric in close relation with the
selvedge carriers and feeders, whereby the sagging of the fabric in its
passage from the latter to the delivery roll and loss of stretch in the
passage of the fabric to the drying cylinders is avoided, also great
simplicity generally is obtained.
Another feature of the Invention having reference to the tentering
and straightening of fabrics consists in a combination of turntables and
slides, with the selvedge carrying and feeding devices of the tentering
apparatus mounted on or carried by said tables, whereby provision is
made for varying the obliquity and distance apart of the selvedge
carrying and feeding devices.
Another feature of the Invention consists in the combination with
said turntables and slides of upright shafts arranged to occupy con-
centric relations with said tables and pinions and mitre wheels or
toothed surfaces on the selvedge carrying wheels for operating the latter
under various adjustments of the same.
Another feature of the Invention consists in a combination of
separately hung and independently operating selvedge carrying or
stretching and feeding devices on opposite sides of the machine driven
in a positive manner, with facility not only for driving said devices on
one side of the machine and not on the other, but of positively driving
them at different velocities relatively with cach other to adjust the
stretch or feed on opposite sides as required. For this purpose conical
pulleys, belts, and belt strippers are provided for acting independently
on the gearing which transmits the driving motion to the sclvedge
carrying wheels.

page_text: The Invention also consists in a novel combination of devices con-
nected with the obliquely arranged selvedge carrying and stretching
devices for changing the obliquity of the latter as required for driving
the same, and for checking or controlling the one set of such devices on
the one side of the machine relatively to the other set of said devices on
the other side of the machinc.
Again the Invention consists in a stationary friction stretching frame
or drag between the selvedge carriers constructed so as not only to be
capable of expansion and contraction breadthwise of the fabric, but
also, if necessary, of being more or less bowed in or out radially
relatively to the axes of the travelling selvedge carriers, whereby a
very perfect provision is made for regulating the stretch of the fabric
between the selvedges.
The Invention also consists in a longitudinal adjustable or extensible
connecting shaft attached by universal joints to the rotating selvedgo
carriers, whereby a direct central or driving connection is established
between said carriers under all adjustments of the latter, likewise in a
combination of mechanism with said connecting rotating selvedge
carriers for driving the carriers on both sides of the machine from one
side of the latter.
The Invention also consists in a combination with the rotating
selvedge carriers of longitudinally adjustable or extensible and jointed
or free connecting rods, bars, or ribs between the selvedge carriers for
rotation with the latter, and for support of the body of the cloth or
fabric between the selvedge feeding and carrying devices under all
adjustments of the latter.
Furthermore, the Invention consists in a longitudinally adjustable or
expansible delivery roll for the cloth or fabric from the adjustable
selvedge carrying and feeding devices of the machine to suit different
widths of fabrics, likewise in a combination with the longitudinally
adjustable delivery roll of sheaves on the ends of said roll for the
endless belts, bands, or chains of the selvedge carrying and feeding
devices.
Lastly, so far as the tentering and straightening devices of the
apparatus are concerned, the Invention consists in a combination with
a rotating selvedge carrying wheel on either side of the machine of

page_text: spring jaws or clips attached to the wheel, and constituting each one of
the jaws of a series of clamps, the other jaw of which is constituted by
the rim of the carrying wheel, said clamp being made to open and close
for reception and holding of the selvedge of the fabric and for the
liberation of the latter after the tentering and straightening has been
effected, and in this relation the Invention also consists in fixed cam
pieces or their equivalent for automatically controlling the opening and
closing of the jaws. Such spring jaw or clip and selvedge carrying
wheel combinations are mainly applicable to licavy goods, either wide or
narrow, in which the selvedges are of sufficient stoutness to be held and
fed by said clamping devices in a positive manner.
When the fabric is of a gauze-like or light description, and of con-
siderable width, then it is desirable or necessary to use independently
rotating selvedge carriers with endless belts, bands, or chain accompani-
ments in connection with a stationary friction stretching frame or drag
between the carriers, as herein-before described.
For tentering and straightening narrow fabrics, then it is desirable in
many cases to use in connection with selvedge carriers either moving
together or independently of one another, a travelling intermediately
arranged body support, as herein-before specified, instead of a stationary
drag; but it may here be observed that while these several modifications
of tentering and straightening apparatus are more especially designed
for particular and different descriptions or qualities of goods, they are
not necessarily restricted thereto, and some of them or portions thereof
may be combined with the other modifications or certain of them, or
portions of the same.
That portion of the Invention which relates to the drying and
finishing of the fabrics as they come from the tentering and straighten-
ing apparatus, or tentering and straightening portion of an apparatus
in which the drying and finishing devices are a part of it, is applicable
to various kinds of sized or dressed fabrics requiring a softened or what
is known as an elastic finish.
This part of the Invention, which may be used in combination with
any of the several modifications herein-before referred to of tentering
and straightening devices, consists in a combination with the drying
cylinders over or round which the sized or dressed fabric is passed after
it comes from the tontering and straightening devices or apparatus of

page_text: one or more longitudinally reciprocating or traversing cylinders arranged
either above, below, or between the drying cylinders or certain of them,
and round which traversing cylinder or cylinders the fabric is passed for
the purpose of breaking or preventing adhesion by the size or dressing
material of the warp and weft at their places of intersection.

Office on the 21st October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in tho
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Alfred Vincent Newton, Her special licence
that I, the said Alfred Vincent Newton, my executors, administrators,

IN APPARATUS FOR TENTERING, STRAIGHTENING, DRYING, AND FINISHING CLOTH AND
OTHER FABRICS," being a communication to me from abroad by Isaac
Emerson Palmer, of Middletown, in the State of Connecticut, United
States of America, upon the condition (amongst others) that I, the said
Alfred Vincent Newton, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
uinto annexed and to the letters and figures marked thereon (that is
to say) :—
This Invention, so far as it relates to the tentering and straightening
of cloth and other fabrics includes various novel constructions and com-
binations of devices to adapt the Invention to different descriptions and
qualities of fabrics.
One feature of the Invention relating to oblique or diverging selvedge
carrying and feeding devices consists in a tentering and straightening
apparatus in which there is combined with oblique or diverging and
revolving selvedge carriers or wheels a novel arrangement of endless
belts, bands, or chains, made to move in common with said wheels for
holding between them and the wheels the selvedges of the fabric to be
tentered and straightened, pulleys for guiding said bolts, bands, or
chains, and a delivery roll for the fabric in close relation with the
selvedge carriers and feeders, whereby the sagging of the fabric in its
passage from the latter to the delivery roll and loss of stretch in the
passage of the fabric to the drying cylinders is avoided, also great sim-
plicity generally is obtained.
Another feature of the Invention having reference to the tentering
and straightening of fabrics, consists in a combination of turntables and
slides with tho selvedge carrying and feeding devices of the tentering
apparatus, mounted on or carried by said tables, whereby provision is
made for varying the obliquity and distance apart of the selvedge
carrying and feeding devices.
Another feature of the Invention consists in the combination with said
turntables and slides of upright shafts arranged to occupy concentric
relations with said tables, and pinions and mitre wheels or toothed sur-
faces on the selvedge carrying wheels for operating the latter under
various adjustments of the same.
Another feature of the Invention consists in a combination of
separately hung and independently operating selvedge carrying or
stretching and feeding devices on opposite sides of the machine driven
in a positive manner with facility, not only for driving said devices on

page_text: one side of the machine and not on the other, but of positively driving
them at different velocities, relatively with each other, to adjust the
stretch or feed on opposite sides as required. For this purpose conical
pulleys belts, and belt strippers are provided for acting independently
on the gearing which transmits the driving motion to the selvage
carrying wheels.
The Invention also consists in a novel combination of devices con-
nected with the obliquely arranged selvedge carrying and stretching
devices for changing the obliquity of the latter as required for driving
the same, and for checking or controlling the one set of such devices on
the one side of the machine relatively to the other set of said devices on
the other side of the machine.
Again, the Invention consists in a stationary friction stretching frame
or drag between the selvedge carriers, constructed so as not only to be
capable of expansion and contraction breadthwise of the fabric, but also,
if necessary, of being more or less bowed in or out radially relatively to
the axes of the travelling selvedge carriers, whereby a very perfect pro-
vision is made for regulating the stretch of the fabric between the
selvedges.
The Invention also consists in a longitudinally adjustable or extensible
connecting shaft attached by universal joints to the rotating selvedge
carriers, whereby a direct central or driving connection is established
between said carriers under all adjustments of the latter, likewise in a
certain combination of mechanism with said connected rotating selvedge
3 carriers for driving the carriers on both sides of the machine from one
side of the latter.
The Invention also consists in a combination with the rotating
selvedge carriers of longitudinally adjustable or extensible and jointed
or free connecting rods, bars, or ribs between the sclvedge carriers for
O rotation with the latter, and for support of the body of the cloth or
fabric between the selvedge feeding and carrying devices under all
adjustments of the latter.
Furthermore, the Invention consists in a longitudinally adjustable or
expansible delivery roll for the cloth or fabric from the adjustable
5 selvedge carrying and feeding devices of the machine to suit different
widths of fabric; likewise, in a combination with the longitudinally
adjustable delivery roll of sheaves on the ends of said roll for the

page_text: UL
VF
SYGUge Callying and ung
devices.
Lastly, so far as the tentering and straightening devices of the appa-
ratus are concerned, the Invention consists in a combination with a
rotating selvedge carrying wheel on either side of the machine of spring
jaws or clips attached to the wheel, and constituting each one of the
jaws of a series of clamps, the other jaw of which is constituted by
the rim of the carrying wheel, said clamp being made to open and close
for reception and holding of the selvedge of the fabric and for the
liberation of the latter after the tentering and straightening has been
effected; and in this relation the Invention also consists in fixed cam
pieces or their equivalent for automatically controlling the opening and
closing of the jaws. Such spring jaw or clip and selvedge carrying
wheel combinations are mainly applicable to heavy goods, either wide or
narrow, in which the selvedges are of sufficient stoutness to be held and
fed by said clamping devices in a positive manner.
When the fabric is of a gauze-like or light description, and of con-
siderable width, then it is desirable or necessary to use independently
rotating selvedge carriers with endless belts, bands, or chain accom-
paniments in connection with a stationary friction stretching frame or
drag between the carriers as herein-before described.
For tentering and straightening narrow fabrics it is desirable in many
cases to use in connection with selvedge carriers either moving together
or independently of one another, a travelling intermediately arranged
body support as herein-before specified instead of a stationary drag;
but it may here be observed that while these several modifications of
tentering and straightening apparatus are more especially designed for
particular and different descriptions or qualities of goods, they are not
necessarily restricted thereto, and some of them, or portions thereof, may
be combined with the other modifications or certain of them or portions
of the same.
That portion of the Invention which relates to the drying and finishing
of the fabrics as they come from the tentering and straightening
apparatus, or tentering and straightening portion of an apparatus in
which the drying and finishing devices are a part of it, is applicable to 3
various kinds of sized or dressed fabrics requiring a softened or what is
known as an elastic finish.

page_text: Fig. 11 a view in perspective of one of the spring jaws or clips as applied
to the revolving carrying wheel shown only in part.
Referring in the first instance, or more particularly to Figures 1, 2,
3, and 4, of the Drawing A, A, are the diverging or obliquely arranged
selvedge carrying wheels on opposite sides at the one end of the appa-
ratus, and on to or between which and endless bands or chains B, B,
moving in common with said wheels the sclvedges of the fabric R to
be tentered and straightened are passed. Said fabric is introduced to
the apparatus under a roller or bar & in front and so that its selvedges
pass upwardly to or over the selvedge carrying wheels A, A, and under
the holding bands or chains B, B, on the narrowest or most contracted
side of said devices, while the body of the fabric passes up over an inter-
mediate stretching frame or drag.
The selvedge holding bands or chains B, B, which in connection with
the wheels A, A, from the selvedge feeding and carrying devices may
be variously arranged and driven. They are here shown however as
occupying an outside relation as regards both their upper and lower
courses of travel to the peripheries or rims of the wheels A, A, the
same passing over guide pulleys or rollers C, O, and sheaves D, D,
attached to or forming part of the delivery roll E, said rollers and
sheaves having their peripheries opposite to or facing, and in close
proximity with the peripherics or rims of the wheels A, A, over which
the bands B, B, also pass to give the necessary hold on the selvedges of
the fabric as the latter is introduced at its selvedges between the bands
and wheels under the guide pulleys C which are furthest from the delivery
roll E.
This combination of the endless chains or bands B, B, with the selvedge
carrying wheels A, A, is exceedingly simple and direct, thereby avoiding
all twisting of the bands by reason of their guiding and carrying devices
being in parallel axial relation, or nearly so, with each other, and it
furthermore dispenses with any great multiplicity of guiding pulleys or
rollers and provides for a close arrangement of the delivery roll E with
the sclvedge carrying and feeding devices, whereby all lost space pro-
ducing sagging of the fabric between said roll and the selvedge carrying
and feeding devices is done away with. The same side or end frames
F, F, which carry the revolving selvedge carriers also support or carry
by adjustable band tightening branches or attachments the guiding
pulleys or rollers C, O,

page_text: It is immaterial so far as this combination of selvedge carrying and
feeding devices is concerned, whether the wheels A, A, or the bands
B, B, be the drivers of the fabric, or whether the fabric be used to drive
said devices by its selvedges being drawn in between the bands and
wheels that move in common. Said devices however will herein-after be
referred to as being both selvedge feeders and carriers, and instead of
driving the bands by the delivery roll E, the wheels A, A, will be made
the drivers.
Furthermore, while the selvedge carrying wheels might be connected
to rotate in common at a uniform velocity, and the same have an
invariable distance apart, also a fixed obliquity or diverging relationship
with each other it is desirable for working certain kinds of goods, as
herein-before mentioned, to provide for different adjustments of said
selvedge feeding and carrying devices. Thus the frames F, F, on or by
which the sclvedge carrying wheels A, A, and their bands B, B, aro
supported are constructed to form turntables, whereby the obliquity of
the selvedge carrying wheels and their respective holding bands may be
changed as required. This is done independently as regards the two
sets of sclvedge controlling devices on opposite sides of the apparatus
by means of screws c and worm wheels or sectors & connected with the
turntables F. These turntables F are carried by slides G adjustable by
means of right and left hand scrow threads e, e, on a shaft H along a
lower cross bed or beds I to vary the distance apart of the sclvedge
carrying and holding or stretching devices.
The selvedge carrying wheels A, A, which may if desired be of any
suitable clastic or roughened construction on their peripheries, arc
driven by bevil pinions K, K, arranged to gear with mitre wheels or
surfaces L, L, on the outer faces of the selvedge carrying wheels, the
shafts of said pinions passing down through lower studs or sleeves of
the turntables F, and carrying on their lower ends bevil pinions M, M,
which gear with bevil pinions N, N, on independent lower horizontal
shafts O. These independent shafts O may either be operated directly
or indirectly through gearing g, h, and countershafts i by conical
pulleys P, P, to either or both of which motion is communicated by
bands or belts j, j, from conical pulleys Q, Q, fast on a general or main
horizontal driving shaft T. This arrangement or combination of devices
admits of one set of selvedge carrying and feeding devices being run or
driven in a positive manner at a different velocity from those on the

page_text: other side of the apparatus, or the one set of said devices may be
temporarily arrested to provide for various contingencies, as regards the
run of the fabric at the onc selvedge relatively to the other or to the
body of the fabric. This is done by shifting the belts j, j, which connect
the conical pulleys Q, Q, with the independently operating conical 5
pulleys P, P, by means of sliding belt shifters S, S. These belt shifters
may be actuated in various ways, but preferably by the feet of the
operators, as for instance, by means of pinions U carried by slides and
arranged to gear with sliding racks V carrying the belt shifters, the
shafts 1, 1, of said pinions being provided with foot rolls W, for the 10
purpose of enabling the operators to actuate the pinions to the right or
to the left as required, by merely slightly working the foot on or
over the rolls.
Instead of the foot rolls being on the shafts 1, 1, the said shafts may
be geared by bevil gears with two short horizontal shafts arranged 15
parallel with the shafts O, and the foot rolls may be arranged on these
two shafts in a position near together to be conveniently worked by onc
operator sitting in front of the machine.
The combination of the primary conical pulleys Q, Q, and secondary
independently operating conical pulleys P, P, for separately or indepen- 20
dently regulating the motions of the two sets of selvedge carrying and
feeding or holding devices on opposite sides of the apparatus constitutes
a very simple and effective means for attaining the desired end.
Furthermore, by the concentric arrangement of the shafts with the
turntables F, the turning of the tables in no ways interferes with the 25
driving of the wheels A, A, under all adjustments of the latter.
To provide for the setting in or out relatively to each other of the
selvedge carrying wheels A, A, by the movement of the slides G along
the bed or beds I, the pinions N should be fitted to slide by feather on
the independent shafts O which carry them, or other provision should be 30
made for the adjustment of the said gear.
The delivery roll E, beneath which the fabric passes in an upward
direction to the first of a usual or any suitable series of drying rolls A³,
is arranged across the apparatus at the back of the wheels A, A, that is
on the diverging sides of their peripheries, and as herein-before observed 35
in close relation with the latter, whereby loss of stretch in the fabric in

page_text: its passage to the drying cylinders is prevented by reason of the selvedge
carrying and feeding devices having hold on the fabric till it passes
under the delivery roll. This roll E may have applied to it some means
of producing friction to act as a brake in order that it may produce a
drag on the fabric.
In some cases instead of a delivery roll a bar might be used, but the
roll with friction is preferable, said delivery roll E, as shewn in the
Drawing, is made capable of extension and contraction by constructing
it in a telescopic manner of longitudinally or sliding and extensible
sections to conform to the adjustments of the sclvedge carrying and
feeding devices when the latter are made adjustable, as herein-before
described. The sheaves D, D, round which the bands B, B, pass may
either be rigidly or loosely attached to said roll, but it is preferred to
have them free or loose on the ends of tho roll.
When it is not desired to maintain at a fixed tension the stretch of the
fabric between the delivery roll or device and the first drying cylinder,
then the selvedge carrying and feeding devices, and the delivery roll or
device may be moved in common further away from the first drying
cylinder than is shown for the arrangement represented in Figure 1 of
the Drawing.
The friction frame or drag (sec Figures 1, 2, and 4) interposed between
the selvedge carrying and feeding devices, for stretching the fabric
between its selvedges, and preventing its body from running ahead of
the selvedges is, that is for a certain class of goods, of stationary con-
struction, and is preferably composed of any desired number of divided
stringers extending across the machine, and so that the same are not
only capable of being expanded or contracted in a transverse relation
with the feed or run of the fabric over them, but also capable of being
set straight or of being bowed in or out radially in relation with the
travelling selvedge carriers for the purpose of adjusting the stretch on the
body of the fabric. To this end the stringers composing the drag are
made up of longitudinally slotted bars B', B', and C', C', with or without
wings D', D¹, the whole being carried in an adjustable manner as regards
setting them in or out relatively to the axes of the wheels A, A, by
'means of attached sliding rods or guides 6', entering fixed standards E',
and retained in position therewith by set screws or otherwise, and the
centre bars C¹, C¹, of cach stringer being jointed or pivotted to cach
other as at c¹.

page_text: It is preferred to leave a wide vacant space as at G¹ between thiese
stringers composing the drag in the upper portion of the latter, for the
purpose of allowing the fabric by slightly sagging, to adjust or recover
itself if unduly or irregularly stretched in its passage over the drag.
Referring in the next instance to Figures 7 and 8, of the Drawing
A, A, are the diverging or obliquely arranged solvedge carrying wheels
or revolving devices on opposite sides of the machine or tentering portion
of the apparatus, and B, B, the endless bands moving in common with
said wheels to unite with the latter, for carrying and feeding the fabric
to and under the delivery roll E. These wheels, bands, and roll, as also
the turntables F, F, which support the selvedge feeding and carrying
devices, may all be constructed and arranged for operation substantially
as herein-before described, but to adapt said tentering and straightening
devices to different kinds of goods as herein-before referred to, the modi-
fication shewn in Figures 7 and 8 has the wheels A, A, connected to
uniformly rotate in common and so that not only the one wheel A. is
made to feed or drive at a time but both wheels A, A, to simultaneously
and equally operate in a positive manner, and the frame which supports
the body of the fabric between the selvedge carrying and feeding devices
is made to move in common with the wheels A, A, either by attachment
to the latter or otherwise. Thus the selvedge carrying wheels A, A, are
connected by a sectionally constructed and longitudinally adjustable or
extensible central shaft H', which is united with said wheels by universal
joints d', d, and a positive driving motion is communicated to both of
said carriers or wheels from the one side of the machine only by means
of a bevil pinion f¹, which may be adjusted along a driving shaft I', and
which gears with a bevil wheel h³, on the shaft of which is a bevil pinion
, that gives motion to a bevil wheel fast on the face of the one selvedge
carrier A. Connecting the selvedge carrying wheels A, A, at or near their
peripherics by pivotted or jointed attachments 1, 1, are sectionally con-
structed and longitudinally adjustable or extensible rods, bars, or ribs J',
J', which thus rotate in common with the wheels A, A, and are capable of
adjustment therewith, and which constitute a frame to support the body
of the cloth or fabric, as the latter is simultaneously carried at its
selvedges by the selvedge carrying or carrying and feeding devices.
Instead of this fabric supporting frame being attached to the wheels
A, A, it might be independent of them and be separately rotated in
proper relation with said wheels.

page_text: Referring in the next instance to Figures 9, 10, and 11 of the Draw-
ing, which shows a modification of the selvedge carrying and feeding
devices applicable to heavy goods, both wide and narrow, having strong
or stout selvedges, each revolving selvedge carrying a feeding device on
opposite sides of the machine is constructed substantially as follows :—
A is the revolving selvedge carrying wheel, which may be supported on
a turntable F, made capable also of sliding to provide for the varied
adjustments of the sclvedge carrying and feeding devices, both as regards
the oblique or diverging relation of the same, and as regards their
distance apart on opposite sides of the machine. Applied to the off or
outer side of this carrying wheel for rotation along with it are a series
of spring jaws or clips O³, arranged to overlap the rim of the carrying
wheel, for a portion at least of its width, and serving to hold between
them and the rim of the carrying wheel the selvedge of the fabric while
the latter is being tentered and straightened by its feed or motion, in
common with the selvedge carrying and feeding devices on opposite sides
of the machine. These clamping jaws C³ remain closed during the upper
portion of their travel, but open at any convenient points on approaching
and leaving their upper course of travel, to receive the selvedge of the
fabric in between them and the carrying wheel, and to liberato said
selvedge after the tentering and straightening has been effected, the rim
of the carrying wheel forming the one jaw of the clamps.
A convenient construction and combination of devices for such
purpose
and for securing a proper action of the clamping jaws or clips is shewn
in Figures 9, 10, and 11 of the Drawing. Thus the jaws C* have a
radial relation around the outside of the carrying wheel A, and are con-
nected by springs & with a ring or annular rod c² as a centre of motion
when opening and closing, and to give to said jaws or clips an elastic
action.
Furthermore, the back or outer ends of the jaws or clips Cs are con-
structed with cars d, which as said jaws are rotated in common with
the carrying wheel pass within or against fixed cams D², D², on opposite
sides of the axis of the carrying wheel to automatically operate or open
the clamps against the closing action of the springs b² at the necessary
points in the travel of the clamping jaws or clips for reception and
liberation of the selvedges, as hercin-before described.
Referring once more to Fig. 1, and to Figures 5 and 6 of the Drawing
by way of describing that portion of the Invention which relates to the

page_text: drying and giving a softened, or what is known as an elastic finish to
the fabric, the means or combinations of devices of which this part of
the Invention is composed are applicable to the manufacture of sized
or dressed fabrics of various kinds, irrespective of any particular con-
struction of the tentering and straightening portion of the apparatus.
A¹ are drying cylinders, such as used in the manufacture of sized or
dressed fabrics, and round which the fabric R as it comes from the
tentering and straightening apparatus is passed; E³, E³, arc also
cylinders, of which there may be any number, that is, one, two, or
more, arranged cither above, below, or between the ordinary drying
cylinders, so that the fabric in its passage through the drying apparatus
or drying portion of the combined tentering and drying apparatus passes
over or round said cylinders E³, E³. These cylinders E³, E³, have a
longitudinally reciprocating or traversing motion in a transversc
direction relatively to the passage of the fabric through the apparatus,
as for instance by means of revolving cranks G³, G³, made to vibrate
swinging arms H³, H', which together with the corresponding arms I³, I³,
on the opposite side of the apparatus carry the cylinders E³, E³. Said
cylinders E³, E³, may if desired also be drying cylinders, and cither be
of a perforated or close construction. They may also be either free to
independently rotate on their respective axes, or be positively rotated by
means of gearing, as customary with the drying cylinders A'. It is the
longitudinally reciprocating or traversing motion however of the
cylinders E³ which operates to break the adhesion caused by the size or
dressing material at the intersection of the warp and weft which serves
to give the elastic finish to the fabric, as the latter in its passage through
the apparatus travels round said cylinders.
Having now described the Invention of "Improvements in Apparatus
for Tentering, Straightening, Drying, and Finishing Cloth and other
Fabrics," as communicated to me by my foreign correspondent, and
having explained the manner of carrying the same into effect, I wish
