Year: 1870

page_text: LETTERS PATENT to James Denby Lee and James Crabtree, of
Shipley, near Leeds, in the County of York, Machine Makers and
Iron Founders, for the Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING."
Sealed the 13th June 1871, and dated the 19th December 1870.
PROVISIONAL SPECIFICATION left by the said James Denby Lee and
James Crabtree at the Office of the Commissioners of Patents, with
their Petition, on the 19th December 1870.
We, JAMES DEnby Lee and James Crabtree, of Shipley, near Leeds,
in the County of York, Machine Makers and Iron Founders, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING," (to be as follows): :-
This Invention relates to "rising box looms or those having change
shuttle box, and chiefly to that class employed in the weaving of
woollens or heavy textile fabrics, and the improvements consist in a new
combination and arrangement of means or apparatus for effecting the
rising and falling or change of shuttle boxes as follows:-A lever is

page_text: hinged to the low part of the loom end frame, one end of such lever
being connected by a rod to the boxes, and the other end provided with
a weight to balance the said boxes. A peg wheel is fixed on the tappet
shaft the peg of which is capable of taking into and giving intermittent
rotary motion to a star wheel mounted on a short shaft carried in a
bracket fixed to the loom end. On this shaft is also a two-nosed tappet
fixed in suitable position so as to act upon the lever. An ordinary
jacquard cylinder is mounted in a frame capable of sliding in another
bracket fixed to the loom end, and so that the cylinder will rotate and
also move up and down. A spur wheel is carried on a stud fixed to the
loom end, which wheel is in gear by means of an intermediate spur wheel
with another spur wheel fixed on the crank shaft. On the side of the
first-named spur wheel is fixed a stud forming a crank pin, which by
means of a connecting rod gives a slide motion to the cylinder frame.
On the end of the cylinder is fixed a star wheel, which is operated by a
peg or pin formed on or attached to the said rod and thereby gives
intermittent motion to the cylinder. The said cylinder carries an
ordinary chain of punched cards or plates suitably arranged according to
requirement. The first-named star wheel is capable of sliding on its
shaft into or out of position for contact with the peg wheel. The slide
motion of this star wheel is effected by a bell-crank lever, one end forming
a fork which takes into a groove on the boss of the wheel, and the other
end is connected to one end of a hooked rod the other end of which is in
position to be acted upon or operated by the cards or plates when no hole
is presented to the said end of it, and thereby moving the said star wheel
into position to be operated by the peg on the peg wheel, which thereby
changes the shuttle boxes, but when a hole in any of the plates is
presented to the end of the rod no action on the star wheel takes place,
and consequently no change is made in the shuttle boxes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 30
filed by the said James Denby Lee and James Crabtree in the Great
Seal Patent Office on the 19th June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
DENBY LEE and JAMES CRABTREE, of Shipley, near Leeds, in the County
of York, Machine Makers and Iron Founders, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of December, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs. and successors, give and
grant unto us, the. said James. Denby Lee and James Crabtree, Her
special licence that we, the said James Denby Lee and James Crabtree,
our executors, administrators, and assigns, or such others as we, the
said James Denby Lee and James Crabtree, our executors, adminis-
trators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter 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 LOOMS FOR
WEAVING," upon the condition (amongst others) that we, the said James
Denby Lee and James Crabtree, our executors or administrators, by an
instrument in writing under our, or their, or one of our or 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.
NOW KNOW YE, that we, the said James Denby Lee and James
Crabtree, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, and accompanying
Sheet of Drawings (that is to say) :-
:-
This Invention relates to " rising box" looms or those having change
shuttle boxes, and chiefly to that class employed in the weaving of
woollens or heavy textile fabrics, and the improvements consist in a
new combination and arrangement of means or apparatus for effecting
the rising and falling or change of shuttle boxes as follows:-A lever
is hinged to the low part of the loom end frame, one end of such lever
being connected by a rod to the boxes, and the other end provided with
a weight to balance the said boxes. A peg wheel is fixed on the tappet
shaft, the peg of which is capable of taking into and giving intermittent
rotary motion to a star wheel mounted on a short shaft carried in a
bracket fixed to the loom end. On this shaft is also a two-nosed tappet
fixed in suitable position so as to act upon the lever. An ordinary

page_text: jacquard cylinder is mounted in a frame capable of sliding in another
bracket fixed to the loom end, and so that the said cylinder will rotate
and also move up and down. A spur wheel is carried on a stud fixed
to the loom end, which wheel is in gear by means of an intermediate
spur wheel with another spur wheel fixed on the crank shaft. In the
side of the first-named spur wheel is fixed a stud forming a crank pin,
which by means of a connecting rod gives slide motion to the cylinder
frame. On the end of the cylinder is fixed a star wheel which is operated
by a peg or pin formed on or attached to the said rod, and thereby gives
intermittent motion to the cylinder. The said cylinder carries an
ordinary chain of punched cards or plates suitably arranged according
to requirement. The first-named star wheel is capable of sliding on its
shaft into or out of position for contact with the peg wheel. The slide
motion of this star wheel is effected by a bell-crank lever, one end
forming a fork which takes into a groove on the boss of the wheel, and
the other end is connected to one end of a hooked rod, the other end
.of which is in position to be acted upon or operated by the cards or
plates when no hole is presented to the said end of it, and thereby
moving the said star wheel into position to be operated by the peg on
the peg wheel, which thereby changes the shuttle boxes, but when a
hole in any of the plates is presented to the end of the rod no action on
the star wheel takes place, and consequently no change is made in the
shuttle boxes

page_text: on a stud fixed to the loom end and in gear by intermediate wheel L
with another spur wheel M fixed on the crank shaft. A stud may be
fixed in the side of this wheel to form a crank, but in this case we have
an eccentric N fixed to the boss of a peg wheel P which is fixed to the
said wheel K, and a strap with rod Q connects it with the boss H for
giving the up-and-down motion to the cylinder G, and on the shaft of
which is fixed another star wheel S, which is operated by the peg wheel P
at each revolution, whereby the cylinder is turned intermittently. A
chain of cards or metal plates, punched according to design on the
pattern required, is carried by the cylinder. The star wheel E is slidable
on the shaft by means of the bell-crank lever T, one arm of which is
forked and clips in a groove of a boss on the said star wheel, the other
arm being connected to a hooked rod U, which the cylinder operates or
lifts on its rising when no hole in the card or plate is presented to the
end of the said hooked rod, which by being lifted the star wheel E is
placed in position to be operated by the peg wheel D, and thereby moves
the tappet F intermittently, which either rises or lowers the boxes
according to the arrangement of the holes in the card or plates, as will
be fully understood by all practical weavers.
In looms having "rising" boxes at both ends a similar arrangement of
lever A and other parts in connection herein-before described is applied
to the other end of the loom, but it is indicated and actuated by the
same jacquard cylinder, another hooked rod V being employed for the
purpose, which is connected to one arm of a bell-crank lever W, the other
arm being connected by shackle X to a slide rod Y, which communicates
the action to the apparatus at the other end of the loom.
We also employ this apparatus for indicating the picking of the
shuttles at proper times by having the picking cones loose on the shafts,
and having clutches or catch boxes slidable on a square part or feather
on the said shafts, which clutches are placed out of or into connection
with the picking cones at the time required by forked levers, indicated
and actuated by the aforesaid apparatus.
I
Having thus fully described the nature of our said Invention, and
shewn by Drawings in what manner the same is or may be performed
or carried into practical operation, we would have it understood that
we do not confine ourselves to the precise details shewn and described;
but what we claim is, the combination and arrangement of means or

page_text: apparatus for the purposes set forth in manner substantially as herein
described and shewn by the accompanying. Drawings.
In witness whereof, I, the said James Denby Lee, for and on behalf
of myself and the said James Crabtree, have hereunto set my
hand and seal, this Sixteenth day of June, in the year of our
Lord One thousand eight hundred and seventy-one.
Signed, sealed, and delivered by the.
within-named James Denby Lee,
