Improvements in Cutting or Shearing Machinery used in the

We, WILLIAM STEAD, a Director of Sir Titus Salt Bart. Sons & Co. Limited,
Manufacturers, JAMES PEARSON, Manager, and WILLIAM JAMES MONK,
Engineer, all of Saltaire near Shipley in the County of York do hereby declare
the nature of this invention to be as follows:-
The object of this invention is in cutting or shearing machinery used in the
manufacture of woven fabrics to provide means to stop the machine, lower and
raise the bottom bed, or lift and lower the cutting cylinder, where the piecings of
the two ends, or any damaged place in the fabric is about to pass under the cutting
cylinder, so that the piecing or damaged place will pass clear thereof.
In carrying out this invention one method whereby the machine may be stopped
is as follows we fix rods or detectors at the front and back of the machine the width
of the fabric to be operated on, resting upon or under the fabric, and secured to
shafts fixed across the machine with suitable arrangement of levers that may come
in contact with a spring, arm, or other part so that any thick piece, rod or button
passing under or over the rod will give motion to levers releasing the spring, arm
or other part which being released may throw the belt onto the loose pulley and
stop the machine.
On the other end of the said shafts may be secured levers connected to a rocking
piece, tumbler or equivalent part so that the piecing or any thick place passing
under the rods or other detectors give motion to the levers or arms lifting a tumbler
or rocking piece and allowing an operating arm or part to engage a stud or
equivalent on a disc or support at the same time moving the operating arm out of
position, the operating arms being secured to a rocking lever or carrier which being
actuated by an eccentric operates the disc or support of equivalent kind and lowers
the bottom bed.
The piecing passing under the cutting cylinder and under the rod or detector at
rear of machine gives motion to the operating arms and the tumbler which moves
the one operating arm clear of the stud, and allows the other operating arm to
engage another stud or equivalent part on disc and raises the bottom bed in position
again, by moving a small lever in the series of parts we are enabled to lower and
raise the bottom bed, or lift and lower the cutting cylinder, without stopping the
machine.
The desired stoppage of the machine, lowering and lifting of the bottom bed or
lifting and lowering of the cutting cylinder so as to render the shearing edges
inoperative during passage of a certain portion or portions of the tissue or cloth
may be effected in an equivalent manner to the example given.

Improvements in Cutting or Shearing Machinery used in the
Manufacture of Woven Fabrics.
We WILLIAM STEAD, a Director of Sir Titus Salt Bart., Sons & Co. Limited,
Manufacturers JAMES PEARSON Manager and WILLIAM JAMES MONк Engineer
all of Saltaire near Shipley in the County of York, do hereby declare the nature of
1

page_text: this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of this invention' is in cutting or shearing machinery used in the
manufacture of woven fabrics to provide means to stop the machine, lowor and raise
the bottom bed, or lift and lower the cutting cylinder, where the piecings of the 5
two, ends, or any damaged place in the fabric is about to pass under the cutting
cylinder so that the piecing or damaged place will pass clear thereof.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews an end view of the machine and
Fig. 2 an end view of the same looking from the opposite end of the machine.
Fig. 3 shews by a similar view to Fig. 1, a slightly modified arrangement of
mechanism for attaining the same object.
Fig. 4 shews a portion of parts as shewn in Fig. 2, but in a modified position as
hereafter described.
In carrying out this invention one method whereby the machine may be stopped,
is as follows; we fix rods or detectors A, A' at the front and back of the machine
the width of the fabric to be operated on said rods resting upon or under the
fabric, and secured to shafts B, B1 fixed across the machine with suitable arrange-
ment of levers C, D, D₁ that may come in contact with a spring, arm, or other
part S so that any thick piece, rod, or button passing under or over the rod A will
give motion to the levers C, D, D' releasing the said spring, arm,.or other part S
which being released may throw the belt onto the loose pulley and stop the
machine.
On the other end of the said shafts B, B' (Fig. 2) are secured levers E.E'
connected to a rocking piece, tumbler or equivalent part F so that the piecing or
any thick place passing under the rods or other detectors A. (front of machine)
gives motion to the levers or arms, C and E lifting the tumbler or rocking piece F
and allowing an operating arm or part G to engage the stud or equivalent H¹, on a
disc or support H, at the same time moving the operating arm G, out of position,
the operating arms G, G¹ being secured to the rocking lever or carrier I which
being actuated by the eccentric K, operates the disc or support of equivalent
kind H and lowers the bottom bed.
The piecing passing under the cutting cylinder and under the rod or detector A¹
at rear of machine, gives motion to the operating arms G₁, E, and the tumbler F
which moves the one operating arm G clear of the stud H', and allows the other
operating arm G' to engage another stud or equivalent part H herein shewn as on
the disc H and raises the bottom bed into position again, by moving the small
lever D¹ in the series of parts (Fig. 1) we are enabled to lower and raise the
bottom bed, or lift and lower the cutting cylinder, without stopping the machine.
Referring to Figs. 2 and 4:-The operating arms G. G' are kept clear of the
studs or equivalents H¹ H on the disc or support H by the points F' on tumbler
or rocking piece F until required. Lifting over the tumbler or rocking piece Fat
the same time moving the operating arm or part G¹ clear of the stud or its
equivalent H' on the disc or support H, and allowing an operating arm or part G
to engage the stud or equivalent H' on a disc or support H, the disc or support H
being secured to one end of a shaft S running across the machine on which are
secured 2 levers T and rods V connected to the bottom bed, the operating
arms G G¹ being secured to the rocking lever or carrier I which being actuated
by the eccentric K operates the disc or support or its equivalent H part of a
revolution and lowers the bottom bed.
In Fig. 3 the form of the levers C, D, and D' are slightly modified in form and
relative position but their operation is the same as in Fig. 1. A being the rod
which is actuated as already stated so that the passage of any thick piece or the
like passing under the detector A will cause stoppage of the machine.
The desired stoppage of the machine, lowering and lifting of the bottom bed, or

page_text: lifting and lowering of the cutting cylinder, so as to render the shearing edges
inoperative during passage of a certain portion or portions of the tissue or cloth,
may be effected in an equivalent manner to the example given.
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
The combinations or arrangements and use of parts of apparatus employed in
shearing or cutting the surface of woven fabric so that the passage of a thick piece,
rod, button or inequality will operate a set of levers and cause the stoppage of the
machine, substantially as set forth.
