I, JOHN WILLIAM SLATER, of Dunscar Bleach Works, Dunscar, near Bolton, in the
County of Lancaster, Bleacher and Farmer, do hereby declare the nature of iny said
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to a new or improved machine for stretching textile fabrics
and is designed to operate on the latter in an even and regular manner across the
width of the fabric so as not to disfigure or damage the same. In suitable framework
are mounted grooved metallic or other rollers driven by toothed gearing or by
friction gearing from any suitable or convenient position. The cloth or textile
fabric to be operated upon is fed into the machine from any convenient source, being
guided therein by rollers with grooves to receive straps or cords, the said rollers
being composed of either wood, metal, or other suitable material. The top and
bottom rollers are provided with any desired number of grooves with flat or other
suitable faces to receive a number of endless belts or straps which are mounted on
two or more rollers disposed on either side of the machine, the said endless belts
or straps being maintained in their true working position by dancing or swinging
pulleys and weights placed underneath, the weight of the weights being regulated
according to the class or quality of the cloth to be operated upon. The cloth to be
treated is guided by the endless belts or straps so as to pass between the before
named grooved rollers, after which it is delivered to any desired position, from whence
it may be doffed or batched in the usual manner. A suitable fish-back" plate
or plates may be disposed at any convenient point or points over which the cloth or
fabric passes in its passage from the machine to the " doffing or batching frame.
The machine is provided with a horizontal shaft mounted in bearings, and the said
shaft is provided with bevel wheels gearing with bevel wheels mounted on vertical
shafts or spindles provided with screws or threads for raising and lowering the top
roller to produce an equal movement and pressure at both ends. The machine is
provided with a suitable index arrangement for indicating the setting of the top
roller to ensure of an identical position and even set or pressure being produced
on each end of the top roller. The indicating and setting arrangements are provided
with suitable locking arrangements consisting of a screw or screws and hand wheel or
wheels or other suitable equivalents.

Fig. 1-Sheet 1-is a front elevation of my new or improved machine for stretch-
ing textile fabrics. Fig. 2 a plan of same. Fig. 3-Sheet 2-an end elevation, and
Fig. 4 a sectional elevation through line A¹ B' in Fig. 1.
In all the figures the same letters and nuinerals are employed to indicate correspond-
ing parts.
A is the framework of the machine; B top metallic grooved roller; C bottom
metallic grooved roller; D shaft carrying grooved roller B; E shaft carrying grooved
roller C; F driving pulley; G loose pulley; H pulley for driving "doffer," and I
represents the cloth or textile fabric under operation or treatment.
In the framework A of the machine are disposed the metallic grooved rollers B
and C mounted on the centres D and E respectively. The shaft E carrying the
bottom metallic grooved roller C is mounted in the bearings J located in the frame
sides A at each end of the machine, and the shaft D carrying the top metallic grooved
roller B is mounted in the sliding or adjustable bearings K disposed in the frame
sides A at each end of the machine. The bottom metallic grooved roller C and its

page_text: shaft or centre E is provided with the loose pulley G, and fast pulley F by which it
is driven by a belt from any convenient source in the place in which the machine is
located or otherwise. The driving belt is operated from the fast or driving pulley F
to the loose pulley G and vice-versû by the strap fork attached to the sliding rod
in the bearings secured to the framework A of the machine. The sliding rod is
noved by means of the handles f³ secured thereto. The top metallic grooved roller B
is rotated or driven from the shaft E by means of the spur wheel e gearing with the
spur wheel b on the shaft D. The upper ends of the sliding or adjustable bearings K
are each fitted with the threaded bush L secured in position by the nut M. In the
threaded bush I, is mounted the screwed end N of the spindle O; the upper end of
the latter being provided with the bevel pinion P which gears with the bevel wheel Q
fixed on the cross shaft R mounted in the bearings S on the top end of each side
frame A. The cross shaft R is provided with the threaded or screwed end R¹ on
which is located the hand wheel R2 for locking the cross shaft R after the metallic
grooved roller B has been set to produce the desired amount of stretch to the cloth
or textile fabric under treatment. The cross shaft R is actuated to lift and lower the
top metallic grooved roller B by the hand wheel B. To one side of the framework A
of the machine are attached the fixings T provided with the bearings U and W
in which are located the shafts or centres X and X' carrying the rollers Y and Z.
To the opposite side of the framework A of the machine are attached the fixings T¹
provided with the bearings a in which is located the shaft or centre b carrying the
roller c.
The top and bottom metallic grooved rollers B and C may be provided
with any desired number of grooves with Hat or other suitable faces to receive the
endless belts or straps p which are employed for holding the cloth or textile fabric I
against the top roller B when the operation of stretching is being performed.
endless belts or straps are mounted on the rollers C and Z disposed on either side
of the machine as shown in Figs. 2, 3 and 4. The endless belts or straps p are main-
tained in their true working position by the dancing or swinging pulleys ; the latter
being provided with the centre s on which are mounted the metallic links t carrying
the weights underneath; the weight of the weights being regulated according to
the class or quality of the cloth or textile fabric to be operated upon. The endless
belts or straps p, dancing or swinging pulleys and the weights may be duplicated
as often as desired according to the nature, quality, strength, and width of the cloth
or textile fabric I to be operated upon or treated. The cloth or textile fabric I to be
operated upon or treated is guided by the endless belts or straps p so as to pass the
grooved rollers B and C, after which it passes over the "fish-back" plate f from
whence it may be "doffed" or batched in the usual manner. The "fish-back "
plate fis carried from the framework A by the supports or brackets gt. The frame
side A is provided with the index for indicating the setting of the top metallic
grooved roller B, to ensure of an identical position and even "set" or pressure being
produced on each end of the said roller B. The cloth or textile fabric I travels in the
direction indicated by the arrows.
The
In carrying out my said invention I would have it understood that I do not confine
myself to the precise details or configuration of the parts I have shown and described
as the same may be varied or modified without departing from the principle of the
same as they may be constructed and arranged so as to meet the various require-
ments demanded by the trade in the finishing and stretching of textile fabrics.
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 general arrangement, construction, and combination of parts composing the
new or improved machine for stretching textile fabrics as hereinbefore described
and as illustrated in the annexed drawings.
2. In a machine for stretching textile fabrics the use of the metallic grooved
rollers B and C, the roller B being mounted in the sliding and adjustable bearings K
provided with the threaded bush L and nut M, spindles O and screws N, wheels P

page_text: and Q, the latter being mounted on the cross shaft R, and operated in either direction
by the hand wheel B³, and locked by the hand wheel R2 mounted on the screwed
end R¹ the textile fabric being guided by the rollers Y and Z between the metallic
grooved rollers B and C by means of the endless belts or straps p which pass over the
rollers and c, the said endless belts or straps p being regulated in tension by the
rollers and weights v, the whole being operated and applied, substantially as
described and as illustrated in the annexed drawings.
