PROVISIONAL SPECIFICATION.
Improvements in the Construction of Cloth-stretching Machines.
I, CHARLES LOXTON JACKSON of the firm of Jackson and Brother of Wharf
Foundry, Bolton in the County of Lancaster, Engineers, Millwrights, and Iron-
founders, do hereby declare the nature of my said invention to be as follows:
This invention relates to improvements in the construction of machines for stretching
cloth and consists in novel and unique arrangements and disposition of parts to render
this class of machine more useful and occupy less space than hitherto.
In this arrangement of machine the feed and receiving batch rollers are mounted
on the front of the machine to facilitate operation on the cloth and dispense with the
inconvenience of the attendant having to move from one end of the machine to
the other as in machines at present in use. On a bed plate are mounted suitable
standards provided with bearings for carrying a shaft provided with stretching pulleys,
over which the cloth travels in passing through the machine. On this shaft is also
mounted adjustable fixings carrying inclined pulleys, over which straps travel to grip
the selvedges of the cloth to stretch the latter in passing through the machine. The
back side of the frames carrying the inclined pulleys are fitted with slots and sliding
blocks carrying strap tightening pulleys with right and left hand screws and nuts for
operating the same. The tightening pulleys are mounted on centres which admit of
being locked without interfering with their action. To prevent the adjustable fixings
carrying the inclined pulleys dropping when altering the angle of the pulleys a bar is
provided, being held in preparations or supports attached to the main standards of the
machine.
The upper and lower ends of the adjustable fixings carrying the inclined pulleys
are mounted on screws extending to the outside of the machine, worked by endless
chains and wheels so as to admit of one or both ends being operated. This is
effected by means of a clutch arrangement or other equivalents.
On a shaft mounted on the backside of the machine are fixed a number of pulleys
to give additional stretch to the cloth as desired. This shaft is mounted in sliding
bearings operated by screws and hand wheels or other mechanical means. The
batch rollers are mounted in fixings or arms attached to the main standards. The
machine is fitted with suitable driving gear to allow of the various parts being driven
at will.

Improvements in the Construction of Cloth-stretching Machines.
I, CHARLES LOXTON JACKSON of the firm of Jackson and Brother of Wharf
Foundry, Bolton in the County of Lancaster, Engineers, Millwrights, and Iron-
founders, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-

DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of my improved construction and arrangment of cloth
stretching machine.
Fig. 2 is a front elevation, and
Fig. 3 is a plan.
In all the figures the same letters and numerals are employed to indicate corre-
sponding parts.
A, A are frame sides; B, B bearings for carrying main shaft C; D, D adjustable
fixings carrying the inclined stretching pulleys E, E; G are fixed pulleys mounted
on the shaft C; F, F are endless straps or belts on the stretching pulleys E to grip
the selvedges of the cloth H in passing through the machine; I, I are adjustable
tightening pulleys, and J, J are guide pulleys for tightening and guiding the endless
straps F, F on the inclined stretching pulleys E, E; K is the feed batch roller;
L the receiving batch roller; M a spur wheel driven by the spur pinion N on the
shaft O; F is the driving pulley; Q the loose pulley on the shaft O, and R is the
strap for driving the machine from any suitable gearing.
The frame sides A are held together at their upper and lower sides by being bolted
to the stays S. In the latter are disposed the spindles or centres T and T2 provided
with right and left hand screws, on which are mounted the ends of the adjustable
fixings D carrying the inclined stretching pulleys E, E; the said spindles or centres
extending to the outside of the machine to allow of one or both of the same being
rotated at one operation by the hand wheel U, or by the chain wheels V and V
and the endless chain W, or by both combined. The hand wheel U is fitted with the
clutch teeth U¹ which gear or fit into corresponding teeth or openings in the chain
wheel V. When it is desired or necessary to alter the position of the bottom ends of
the fixings D the clutch teeth U on the hand wheel U are out of gear with the
teeth or openings in the chain wheel V as shown in Fig. 2, which allows of the
bottom spindle or centre T being rotated by itself. The chain wheel V is mounted
loosely on the bottom spindle or centre T to allow of the top spindle or centre T2 being
stationary when the bottom spindle or centre T is rotated with the clutch teeth U¹ out
of gear with the corresponding teeth or openings in the chain wheel V. The hand
wheel U with the clutch teeth U₁ is mounted on a key or feather in the spindle
or centre T for the purpose of sliding the clutch teeth U¹ in and out of gear with
the chain wheel V. When it is desired or necessary to alter the position of both
ends of the fixings D the hand wheel U is slid on the spindle or centre T until the

rotate the chain wheel V' and the spindle or centre T it is fixed to.
desired or necessary to alter the position of the upper sides of the fixings D on the
spindle or centre T2 it is effected by sliding the hand wheel U and the clutch teeth U¹
out of gear with the chain wheel V, after which the chain wheels V and V2 and the
endless chain W can be turned or operated in either direction at will. After the
positions of the fixings D have been determined the spindles or centres T and T2 are
locked or secured by means of the lock nuts T³.
The adjustable fixings D D carrying the inclined stretching pulleys E, E are
mounted on ball-bearings on the shaft C in the usual manner to allow of the angle of
the stretching pulleys E, E being adjusted to the amount of stretch required on the
cloth in passing through the machine.
The backside of the adjustable frames D, D are provided with the slots X, X, in
which are mounted the sliding blocks Y, Y carrying the strap tightening pulleys I, I.
The sliding blocks Y, Y can be adjusted in the slots X, X by the right and left hand
screws Z, Z and nuts Z1, according to the amount of tension required by the endless
straps F, F.
The tightening pulleys I, I are mounted on the centres A¹ in the sliding blocks Y,
which admit of the centres A¹ being locked by the nuts B' without interfering
with their action. To prevent the adjustable frames D, D dropping when altering
the angle of the pulleys E, E the bar is provided, being held in the preparations or
supports D' attached to the main standards or frame sides A, A. The adjustable
frames D, D are constructed with the bearings E¹ to rest or slide on the bar (₁. On
the shaft G³, on the backside of the machine, are fixed the pulleys H¹ to give
additional stretch to the cloth as desired. The shaft G¹ mounted in the adjustable
bearings I, which can be slid to and fro by means of the screws J' and hand wheels K'.
The feed batch roller K is mounted on the fixings or supports L' secured to the base
of the frame sides A, A on the front of the machine; and the receiving batch roller L
is carried by the movable arms M₁ pivoted to the fixings N¹, also secured to the
frame sides A, A on the front of the machine, which is an important feature and
designed to dispense with the inconvenience of the attendant having to move from one
end of the machine to the other when batching.
As the
This invention operates in the following manner :-The cloth-represented by the
line H-passes from the feed batch roller K, as indicated by the arrow, under the
roller or guide O' to the inclined stretching pulleys E, E, where the selvedges are
secured on the peripheries of the same by the endless straps F, F.
stretching pulleys E, E rotate the cloth is stretched to the desired width, which is
determined by the angle given to the pulleys E, E by means of the adjustable
frames D, D. The cloth passes round with the pulleys E and endless bands F to
the upper side of the machine, where it is released from the endless bands F and
passes over the roller or guide P₁, then under the roller or guide Q and over the
roller R' to the receiving batch roller L on the front of the machine. The batch
roller Lis mounted in the movable arms M¹ to allow of the same moving to the
increasing diameter of the batch. The movable arms M' are provided with the
levers S and weights T¹ to ensure of the batch being held or pressed against
the batching roller R'; the weights T being adjusted according to the kind of cloth
under operation. To assist the rotary motion of the receiving batch Lit is driven by
contact with the rotating roller R¹ driven from the shaft C by the pulleys U2 and V³
and the strap W'.
Having now particularly described and ascertained the nature of my inven-
tion and in what ir anner the same is to be performed I declare that what I
claim is:-
1. In a cloth stretching machine the construction and arrangement of apparatus
consisting of the spindles or centres T and T2 provided with right and left hand
hand wheel II with the clutch teeth U¹ the chain wheels V and V2 and the
scrowa

page_text: endless chain W- for the purpose, of altering the angle of the frames. D carrying the
stretching pulleys E, substantially as described.
2. The general construction, combination, and arrangement of parts forming my
improved machine for stretching cloth, substantially as herein described and illustrated
by the drawings.
