IMPROVEMENTS IN THE CONSTRUCTION OF POWER LOOMSCLAIMER AND MEMORANDUM OF. ALTER
Year: 1859

page_text: In the Matter of Letters Patent granted to JOHN HIRST, junior, of
Dobseross, in Saddleworth, in the County of York, Merchant, and
JAMES HOLLINGWORTH, of the same Place, Joiner, for the Invention
of "IMPROVEMENTS IN THE CONSTRUCTION OF POWER LOOMS," bearing
date the Second day of February, One thousand eight hundred and
fifty-nine.
DISCLAIMER AND MEMORANDUM OF. ALTERATION proposed to be
entered by the said John Hirst, junior, and James Hollingworth, in the
Great Seal Patent Office, by and with the leave of Her Majesty's Solicitor-
General, pursuant to the Statutes in such case made and provided.
WHEREAS since the filing of the Specification of the said Letters Patent
e have been advised that the second part of the said Invention as therein
ontained does not possess that amount of novelty to render it desirable to
etain the same as part of the said Specification, for which reason we are
esirous of disclaiming as part of our Invention all the parts embraced under
e second head, and the description of the same as contained in the body of
e said Specification. For this purpose we desire at page 3 of the copy of
e said Specification (as published at the Great Seal Patent Office), line 7, to

omit the word "first," also to omit the paragraph beginning at line 17, and
expressed in the following words :-" Secondly, the improvements relate to clear-
ing the wefts when series of rising boxes are used. For this purpose the front
part of the lay is cut away, the filbow is attached to the end of the lay and lay
"sword, and the shuttle boxes at the part adjoining the lay, as is also the lay, are
"bevilled to admit of the weft falling down out of the way of the upper: shuttles;"
also at page 5, line 21, we desire to omit the words, "We will now describe the
"second part of the improvements," retaining the remainder of the paragraph
only, as describing an arrangement of parts which we find it convenient to use
without claiming them as part of the Invention; also at line 36 of the same
page we desire to omit the words "any part of;" and at line 37 we desire to
omit the word "First;" and at page 6 to omit the words " Secondly, the adap-
"tation or arrangement of parts to facilitate the clearing of the weft threads when
" series of sliding boxes are used."
The said Specification as altered will then read as follows:-The improve-
ments relate when series of lifting shuttle boxes are used to operating them
by a series of cams or tappets capable of being slided so as to bring the par-
ticular cam or tappet into position to operate upon the connecting means to the
boxes, in order to the box.required being brought into a line with the race or
lay, and at the same time operating supporting catches to such boxes to release
them to the extent desired, to enable the particular catches alone to come into
position to support the particular box. The sliding to the tappets is effected
by Llever or L levers, operated by chains of pattern surfaces, and such
L levers are held between the changes of surfaces by catches or other suitable
means.
But that the nature of these improvements and the means we adopt in carry-
ing the same into effect may be fully understood, we will proceed to describe
the Drawing annexed.
:
DESCRIPTION OF THE DRAWING.
Figure 1 shows by a sectional end view some of the parts of a loom, with
adaptations thereto arranged according to our improvements; Figure 2 is a
plan view thereof; Figure 3 represents a front view of a portion of one end of
the batten in its relation to the end framing of the loom; 'Figure 4 shews the
parts on a larger scale. In each of the views the same letters are used to
indicate the same parts wherever they occur.

upper ends, and motion is given, as is well understood, from the crank axis 6 to.
the batten by suitable links or connections;, d is a series of three shuttle boxes
1, 2, 3, but this number may be varied, and they are capable of sliding freely
in the end parts of the batten, so as to bring either of them into a line-with the
race of the batten when operated. as we will now explain..
The series of boxes have affixed to them collars d¹; which slide on the guide-
rods d², carried by the end parts of the batten,. by which in the rising and.
falling motion of the boxes they will be controlled to rise and fall correctly.
From the back of the series of boxes projects a stud d³ to receive one end of the
link d'; the other end of which takes on to a stud projecting from the-lever d³, one-
end of which turns upon a stud de, projecting from the sword or arm c³, whilst it
is by the link d' connected to the lever d³, which turns upon the centre of motion.
do, carried by the framing of the loom, and has applied to it the weight d¹º to-
act as a counterbalance to the weight of the boxes; and this weighted end of
the lever ds is, by the link d", connected to one end of the lever e, which turns-
upon the fixed stud e and carries the pulley in position to be operated upon
by one or the other of the cam surfaces f¹ or f³, formed upon or affixed to the
cylinder f, according to the shuttle box of the series desired to be placed in a
line with the race of the lay, and supposing the box 1 be that desired to be-
brought into a line with the lay the cam or tappet surface fi will act on the
truck or bowl e; supposing the box 2 to be that required to be in a line with
the race of the batten, then the cam surface f¹ will operate on the pulley or
wheel e, but if the box 3 is that to be in a line with the race or lay, then
the pulley will be acted upon by the cylinder f, and the cylinder f with its.
surfaces ff, whilst it is controlled to rotate with the axis b, is capable of
sliding thereon to bring the desired surface over the pulley by there being
affixed to or formed thereon the collar f³, which is embraced by the forked
piece affixed to the L lever g', which turns upon a fixed stud g³ from the
bracket a', carried by the loom framing, and this lever g¹ is at its other end
by a link g³ connected to the lower end of a lever g', which turns upon a fixed
stud, whilst it is in position to be acted upon by the projections h¹ from the
chain h, as that chain is carried round by the teeth of the wheel h³ to bring up
a fresh pattern surface; the surfaces of the links of the chain h vary in height
to the amount of motion to be obtained for the sliding of the cylinder f, with
its surfaces ff. The lever g' is kept pressing against the surfaces of the
chain h by means of the spring 96 acting on the lever g'. A step-by-step

page_text: rotary motion is given to the tooth wheel h³ to bring up fresh links of the chain
by there being affixed to that toothed wheel a star wheel ³, acted upon by the
stud and surface of the plate h, as is well understood. i is the picker tappet
for operating the lever in connection with the picker motion, and in order
that the lever may be moved out of the way of the picker tappet i when that
picker is not to act, one end of the lever ¹ is supported upon one end t* of the
L lever ³, which turns upon an axis of motion, and at its other end is, by
the link i, connected to the lower end of the lever ³, the upper end of which
turns upon the axis g³, whilst it is borne by the spring against other projec-
tions on the links of the chain h. In order that when the series of boxes have
been lifted to the desired height they may be held in position till a pick has
been obtained, the lever d³ is provided with stops d", d, either of which is
capable of being acted upon and supported by the upper end of the lever j
which is supported upon the fixed stud j¹, and is borne with its upper end
towards the studs d's, ds, by means of the spring, whilst its lower end is in
position to be acted upon by either of the surfaces f³ or f', to release those
boxes just before the time for effecting a fresh change.
Although we have shewn a chain of surfaces as the means we employ for
effecting the desired changes, jacquard or other pattern surface may be em-
ployed, when catches or other suitable means may be employed to hold the L
levers in position after each selection and till just when another selection is
to be obtained, and these catches may also be used with the chain of
elevations.
It will be seen that the front part of the batten from about the selvage of
the cloth is cut away or bevilled off to k, where the series of boxes joins on
to them and to about the same level, in order that the wefts may hang freely
in front thereof, as indicated by the colored lines, and to facilitate this the
filbow l in place of being attached direct to the lay or batten sword c', as is the
usual practice, is carried down and affixed partly to the portion of the batten
in front of the boxes, to which it serves as a support, and thence underneath
the batten to the sword c¹. The filbow may, however, in place of being carried
down be carried up, and in like manner fastened above the batten. The
shuttle boxes at the end k adjoining the lay, as also that end of the lay, are
inclined.
Having thus described the nature of our said Invention, and the best means
we are acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shown and
described, as these may be varied without departing from the peculiar character

page_text: of our improvements; but what we claim is, the adaptation and combination of
means for operating shifting shuttle boxes.
In witness whereof, we, the said John Hirst and James Hollingworth,
have hereunto set our hands and seals, this Thirtieth day of March, in
the year of our Lord One thousand eight hundred and sixty-one.

page_text: LETTERS PATENT to John Hirst, junior, of Dobscross, in Saddleworth,
in the County of York, Merchant, and James Hollingworth, of the same
Place, Joiner, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
POWER LOOMS."
Sealed the 29th July 1859, and dated the 2nd February 1859.
PROVISIONAL SPECIFICATION left by the said John Hirst and James
Hollingworth at the Office of the Commissioners of Patents, with their
Petition, on the 2nd February 1859.
We, JOHN HIRST, junior, of Dobscross, in Saddleworth, in the County of
York, Merchant, and JAMES HOLLINGWOTH, of the same Place, Joiner, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF POWER LOOMS," to be as follows:-
The improvements relate, when series of lifting shuttle boxes are used, to
operating them by a series of cams or tappets capable of being slided so as to
bring the particular cam or tappet into position to operate upon the connecting
means to the boxes, in order to the box required being brought into a line
with the race or lay; and at the same time operating supporting catches to

page_text: such boxes to release them to the extent desired, to enable the particular
catches alone to come into position to support the particular box.
The sliding to the tappet is effected by L lever or L levers, operated by
chains of pattern surfaces, and such L levers are held between the changes of
surfaces by catches or other suitable means.
Also the improvements relate to clearing the wefts when series of rising
boxes are used. For this purpose the front part of the lay is cut away, the
filbow is attached to the end of the lay and lay sword, and the shuttle boxes at
the part adjoining the lay, as is also the lay, are bevelled to admit of the weft
falling down out of the way of the upper shuttles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hirst and James Hollingworth in the Great Seal
Patent Office on the 2nd August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOHN
HIRST, junior, of Dobscross, in Saddleworth, in the County of York, Merchant,
and JAMES HOLLINGWORTH, of the same Place, Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of February, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said John Hirst, junior, and James Hollingworth, Her special licence that
we, the said John Hirst, junior, and James Hollingworth, our executors,
administrators, and assigns, or such others as we, the said John Hirst, junior,
and James Hollingworth, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and.lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland;
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF POWER LOOMS," upon the condition (amongst others)
that we, the said John Hirst, junior, and James Hollingworth, our executors
or administrators, by an instrument in writing under our or their hands and
seals, or under the hand and seal of one of us or them, 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

page_text: boxes, 1, 2, 3, but this number may be varied, and they are capable of sliding
freely in the end parts of the batten so as to bring either of them into a line
with the race of the batten when operated, as we will now explain.
The series of boxes have affixed to them collars d', which slide on the guide
rods d², carried by the end parts of the batten, by which in the rising and
falling motion of the boxes they will be controlled to rise and fall correctly.
From the back of the series of boxes projects a stud d³ to receive one end of
the link d', the other end of which takes on to a stud projecting from the
lever d³, one end of which turns upon a stud de projecting from the sword or
arm c¹, whilst it is by the link d' connected to the lever a, which turns upon
the centre of motion do, carried by the framing of the loom, and has applied to
it the weight do, to act as a counterbalance to the weight of the boxes. And
this weighted end of the lever d³ is by the link d" connected to one end of the
lever e, which turns upon the fixed stud e² and carries the pulley e² in position
to be operated upon by one or the other of the cam surfaces f¹ or f³, formed
upon or affixed to the cylinder f, according to the shuttle box of the series
desired to be placed in a line with the race of the lay; and supposing the box 1
be that desired to be brought into a line with the lay, the cam or tappet
surface fe will act on the truck or bowl e; supposing the box 2 to be that
required to be in a line with the race of the batten, then the cam surface f¹ will
operate on the pulley or wheel e²; but if the box 3 is that to be in a line with
the race or lay, then the pulley e² will be acted upon by the cylinder f, and the
cylinder f, with its surfaces f¹, f³, whilst it is controlled to rotate with the
axis b, is capable of sliding thereon to bring the desired surface over the pulley
², by there being affixed to or formed thereon the collar f³, which is embraced
by the forked piece affixed to the L lever g', which turns upon a fixed stud 9³
from the bracket a', carried by the loom framing, and this lever g' is at its
other end by a link g³ connected to the lower end of a lever g', which turns
upon a fixed stud g', whilst it is in position to be acted upon by the projections
.h¹ from the chain h as that chain is carried round by the teeth of the wheel h² to
bring up a fresh pattern surface; the surfaces of the links of the chain h vary
in height to the amount of motion to be obtained for the sliding of the cylinder
f with its surfaces f¹, f. The lever g' is kept pressing against the surfaces of
the chain h by means of the spring 9 acting on the L lever g¹. A step by
step rotary motion is given to the tooth wheel h³ to bring up fresh links of the
chain by there being affixed to that toothed wheel a star wheel ³ acted upon
by the stud and surface of the plate h, as is well understood; i is the picker
tappet for operating the lever ¹ in connection with the picker motion, and in

page_text: order that the lever may be moved out of the way of the pickor tappet i when
that picker is not to act, one end of the lever is supported upon one end *
of the L lever, which turns upon an axis of motion ³, and at its other end is
by the link connected to the lower end of the lever, the upper end of. which
turns upon the axis 9%, whilst it is borne by the spring against other
projections on the links of the chain h.
In order that when the series of boxes have been lifted to the desired height
they may be held in position till a pick has been obtained, the lever d³ is
provided with stops ¹³, d, either of which is capable of being acted upon and
supported by the upper end of the lever ; which is supported upon the fixed
study', and is borne with its upper end towards the studs 3, ¹³, by means of
the spring, whilst its lower end is in position to be acted upon by either of
the surfaces for f*, to release those boxes just before the time for effecting a
fresh change..
Although we have shewn a chain of surfaces as the means we employ for
effecting the desired changes, jacquard or other pattern surface may be
employed when catches or other suitable means may be employed to hold the
L levers in position after each selection, and till just when another selection is
to be obtained, and these catches may also be used with the chain of
elevations.
We will now describe the second part of the improvements. It will be seen
that the front part of the batten from about the selvage of the cloth is cut away
or bevelled off to k, where the series of boxes joins on to them, and to about the
same level, in order that the wefts may hang freely in front thereof, as indicated
by the colored lines, and to facilitate this the filbow in place of being attached
direct to the lay or batten sword c', as is the usual practice, is carried down and
aflixed partly to the portion of the batten in front of the boxes, to which it
serves as a support, and thence underneath the batten to the sword c'. The
filbow may, however, in place of being carried down, be carried up, and in like
manner fastened above the batten. The shuttle boxes at the end k adjoining
the lay, as also that end of the lay, are inclined.
Having thus described the nature of our said Invention, and the best means
we are acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shown and
described, as these may be varied without departing from the peculiar character
of any part of our improvements; but what we claim is,-
First, the adaptation and combination of means for operating shifting shuttle

page_text: Secondly, the adaptation or arrangement of parts to facilitate the clearing of
he weft threads when series of sliding boxes are used.
In witness whereof, we, the said John Hirst, junior, and James Holling-
worth, have hereunto set our hands and seals, this Twenty-ninth day
of July, in the year of our Lord One thousand eight hundred and
fifte nine
