Company, of the same Place, Machine Makers, for the Invention of
"
Scaled the 27th April 1869, and dated the 5th November 1868.
PROVISIONAL SPECIFICATION left by the said Samuel Ward, William
Hurst, and John Tuer at the Office of the Commissioners of Patents,
with their Petition, on the 5th November 1868.
We, SAMUEL WARD, of Farnworth, in the County of Lancaster,
Manager, WILLIAM HURST, of the same Place, Manufacturer, and Joun
TUER, of the Firm of Tuer Brothers and Company, of the same Place,
Machine Makers, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The first part of our Invention is applicable to looms in which a
drop box with two or more shuttles is used. In ordinary looms of this
description the shuttle is made with a shoulder acting against a stop in

page_text: the shuttle box. Now our Invention consists in dispensing with the
said shoulder and stop, and in checking the shuttle by means of a check
strap acting on the picking stick, the said check strap being connected
to the shuttle box frame and to the front of the loom side. At the end
of the shuttle box frame is a double-slotted bracket to guide the shuttle
when the drop box rises or falls. By this arrangement the ordinary
straight shuttles may be used in drop box looms; the injury to the
swells and shuttles and the breakage of the shuttle box shells and
picking sticks are reduced.
The second part of our Invention consists in a positive taking-up
motion with one plain roller. As the cloth beam increases in diameter
it raises a lever which is moved to and fro by an eccentric or other
equivalent on the second motion shaft or other part of the loom; this
lever moves the catch of the taking-up ratchet wheel, and the speed
thereof is reduced in proportion to the increasing diameter of the cloth
on the beam. This arrangement simplifies the construction of the loom.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Ward, William Hurst, and John Tuer in
the Great Seal Patent Office on the 4th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
WARD, of Farnworth, in the County of Lancaster, Manager, WILLIAM
HURST, of the same Place, Manufacturer, and JoпN TUER, of the Firm
of Tuer Brothers and Company, of the same Place, Machine Makers,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date tlie Fifth day of November, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Samuel Ward, William Hurst, and John,
Tuer, Her special license that we, the said Samuel Ward, William Hurst,
and John Tuer, our executors, administrators, and assigns, or such others
as we, the said Samuel Ward, William Hurst, and John Tuer, our exe-
cutors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term.

page_text: 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 "CERTAIN IMPROVE-
MENTS IN LOOMS FOR WEAVING," upon the condition (amongst others) that
we, the said Samuel Ward, William Hurst, and John Tuer, 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 monthis next and immediately after the date.
of the said Letters Patent.
NOW KNOW YE, that we, the said Samuel Ward, William Hurst,
and John Tuer, do hereby declare the nature of our said Invention, and
in what the manner same is to be performed, to be particularly described
and ascertained in and by the following statement (that is to say) :-
The first part of our Invention is applicable to looms in which drop-
boxes with two or more shuttles are used. In ordinary looms of this
description the shuttle is made with a shoulder acting against a stop in
the shuttle box. Now our Invention consists in dispensing with the said.
shoulder and stop, and in checking the shuttle by means of a check
strap which is connected to the shuttle box frame and to the front of the
loom side. At the end of the shuttle box frame is a double slotted
bracket to guide the shuttle when the drop box rises or falls. By this
arrangement the ordinary straight shuttles may be used in drop box
looms; the injury to the swells and shuttles and the breakage of the
shuttle box shells or frames and picking sticks are reduced.
The second part of our Invention consists in a positive taking-up
motion with one plain roller. As the cloth beam increases in diameter
it raises a lever which is moved to and fro by an eccentric or other
equivalent on the second motion shaft or other part of the loom; the
lever moves the catch of the taking-up ratchet wheel, and the speed
thereof is reduced in proportion to the increasing diameter of the cloth
on the beam. This arrangement simplifies the construction of the loom.
And in order that our Invention may be fully understood we will
proceed to describe the accompanying Sheet of Drawings.
Figure 1 is a front view of part of a loom to which the first part of
our Invention is applied; Figure 2 is an end view, and Figure 3 a plan
of the same. a. represents the loom side; b, the lay bottom; c, the lay

page_text: sword; d, the drop shuttle box working up and down in the frame e;
, the picking stick; and g the picker moving to and fro on the
spindle g. All these parts are made in the usual manner. To the
shuttle box fram e is bolted the double slotted bracket h, shown full
size in Figures 4 and 5. The face of this bracket comes about in line
with the opening in the frame e that the drop box d works in, and it;
serves to prevent the escape of the shuttles out of the shuttle box, the
nose of the shuttle being guided by the slots ', shewn best in Figure 5.
The end motion of the shuttles is also governed by the check strap i, one
end of which is secured to a bracket cast or fixed to the under side of
the frame e, and the other end is secured to the bracket a' bolted to the,
loom side a. By this improved arrangement the ordinary straight
shuttles, as shewn in dotted lines in Figure 3, may be used in drop box
looms, whereas it has heretofore been necessary to use shuttles having a
shoulder acting against a stop in the shuttle box. The injury to the
swells and shuttles and the breakage of the shuttle box frame and of the
picking sticks are also greatly reduced.
Figure 6 represents our improved taking-up motion, forming the
second part of our Invention. In this view a is loom side; J, the crank
shaft, the tappet or second motion shaft; 1, the breast beam; m, the
taking-up roller; n, the ratchet wheel for driving the roller m by the
pinion n', wheel n², pinion 23, and wheel m' in the usual manner. To
the shaft k is fixed the eccentric k¹. This eccentric in revolving gives a
vibrating motion to the forked lever o, to which is jointed one end of the
link o', the other end of which is jointed to a stud which is capable of
being raised in a slot of the lever p. To this lever is jointed the catch p',
taking into the ratchet wheel n; to the link o' is jointed the lower end
of the rod q, the upper end of which is jointed to the lever q', through-
which the bar passes. The ends of this bar are guided in slots in the
loom sides, and it bears upon the cloth that is wound upon the taking-
up roller m. As the cloth accumulates on the taking-up roller the end
of the link o is gradually raised in the slot of the lever p, thereby
reducing the motion of the taking-up roller m in proportion to the
increasing diameter of the cloth wound upon it. This arrangement
simplifies the construction of the loom and effects a positive taking-up
motion with one plain taking-up roller.
Having thus stated the nature of our Invention, and described the.
manner of performing the same, we declare that we claim.

page_text: First. The improved mode of constructing looms in which drop shuttle
boxes are employed, as shewn and described in reference to Figures 1, 2,
and 3, and particularly the double-slotted bracket h, as shewn detached
in Figures 4 and 5, and connecting the check strap to the shuttle box
frame and to the loom side.
And, secondly. We claim the improved positive taking-up motion
with a single plain taking-up roller, as shewn and described in reference
to Figure 6.
In witness whereof, I, the said John Tuer, have hereto set my
hand and seal, this Third day of May One thousand cight
hundred and sixty-ninc.
