WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Second day of
November, One thousand eight hundred and forty-seven, in the eleventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William James Walker, my exors, adññors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said
William James Walker, my exors, adiñors, and assigns, or such others as I,
the said William James Walker, my exors, adiñors, or assigns, should at any
time agree with, and no others, from time to time and at all times during
the term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN WEAVING;" in which
said Letters Patent is contained a proviso that I, the said William James
Walker, shall cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, by an instrument
in writing under my hand and seal, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William James Walker, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are
fully described and ascertained in and by the following statement thereof,

page_text: reference being had to the Drawings hereunto annexed, and to the figures
and letters marked thereon, that is to say :-
My Invention consists of improvements in arranging and working shifting
shuttle boxes of looms. And in order that the Invention may be understood I
will proceed to describe the same.
The shuttle box is shifted either up and down or back and forward, with
the motion of the lathe by two pins (one for pushing the box up or back, and
the other for letting it down or forward) coming against a shifting surface
opposite the front of the lathe so as to regulate the shifting of the box.
DESCRIPTION OF THE BOX FOR TWO OR MORE SHUTTLES SHIFTING UP AND
DOWN, OR PERPENDICULAR WITH THE RACE OF THE LATHE.
Figure 1.-A, the framework of the loom. B, the crank shaft. D, the
sword of the lathe. 1 is a crank working on the end of the wyper shaft C
with a pulley 2 for lifting the lever 3 working on stud 4, which is fixed to the
side of the loom. 5 a catch connected with lever 3 at 6, which is drawn back
by lifting lever 3 at 7, which catch turns a roller 8 with a square end 9, the
stopper pressing against the square end, 10 a spiral spring for keeping up
the stopper. This roller revolves in a bracket 12 (Figure 4) bolted to the side
of the loom under the breast beam E; on the roller are four pins 13, which
bring up the belt 14, which will be afterwards explained. 15 is a box for three
shuttles sliding on spindles 16 and 17 (Figures 2 and 3) at the back of the
box. There are two inclined planes 19 and 20 (19 seen in Figure 1, and
the ends of both in Figures 2 and 3) for lifting the box. 21 is a catch
working upon studs 23 and 24 (Figures 2 and 3), held by brackets 27 and 28,
screwed to the bottom of the lathe. 26, a spring fixed to the bracket 27 at 29
for pressing the catch 21 against a rest 25 fixed to the bottom of the box.
30 and 31 are seats cut in the catch, the distance from 30 to 31 being the
depth of one of the shuttle boxes. When the shuttle in box 33 is working
the rest 25 is in seat 31, and when the shuttle in 34 is working the rest 25
is in seat 30, as shown in the Figure.
Figure 2.-35 is a piece of iron rivetted to the bottom of the box at
36; 37 and 38 are pins rivetted to the piece of iron 35, which the
inclined planes come against for lifting the box; the distance between
the lower edge of 37, and that of 38 being the depth of one of the boxes.
When the box is fully down the pin 37 will be above the point of the
inclined plane 20 so far as to let it enter underneath the pin. When the
first lift is wanted the inclined plane 20 is pushed back, and coming against
the pin 37 lifts the box so far as to allow the seat 31 (Figure 1) to fall into

page_text: the rest 25, the depth of the inclined plane being a little more than one of the
shuttle boxes. As soon as the inclined plane has lifted the box, which is now
held by the catch 21, it is drawn out by a spring 39 (Figure 3), fastened to
the bottom of the lathe at 40, and connected with the inclined plane at 41.
When the second lift is required the inclined plane 19 presses against the
pin 38, and lifts the box into the position shown in the Figure, when it is
drawn out by the spring 42, Figure 1. The catch 21 is thrown off by a
pin 43, shown as a dotted line, and the end of which is colored blue in Figure 3.
11 is a stationary plate of iron immediately opposite the inclined planes, with
three holes in it, 46, 47, and 48, see Figure 4. The pin 43 enters the hole 46
when the lathe comes forward. The pin 44, Figure 3, fastened to the inclined
plane 20, enters 47, and the pin 45 enters 48.
Figure 5 is a view of the belt, with plates of iron 49, 50, &c., for regulating
the shifting of the box Figure 4. This belt passes over the roller 8; the
pins 13 fit into the holes in the belt, thereby drawing the belt up as the roller
revolves. 55 is a groove in the plate, the depth of the thickness of the belt,
so as to keep the back of the plates 49, 50, &c. flush with the face of the
stationary plate 11. When the small plate 54 is opposite the stationary
plate 11 the hole 47 is covered, so, when the lathe comes forward (the box being
fully down) the inclined plane 20 is pushed in, thereby raising the box the
first lift. When the plate 53 is opposite the hole 48, the inclined plane 19 is
pushed in, which lifts the box to the top. Then, for letting down the box,
the plate 52 covers the hole 46, the pin 43 being so long as to push back the
catch so far as to let the rest 25, Figure 1, fall into the seat 31, when the
plate 51 comes opposite the hole 46, and 51 being made thicker or raised, as
56 pushes the catch farther back, and the box falls to the bottom. The driver
is wrought on one spindle, and has no tongue. 57, Figure 2, is a guide, the
size of one of the boxes, for entering the driver.
Figure 6 shows a plan of the slot. 58 is an eye, which allowing the slot to
yield on the entering of shuttle, and being pressed against the shuttle by the
springs, 59, Figure 2, prevents rebounding.
DESCRIPTION OF THE HORIZONTAL SHIFTING Box.
Figure 10.-60 is a horizontal shifting box for two shuttles, moving
backward and forward on spindles 61 and 62 at the bottom of the box.
The box is pushed back by the pin 63, fixed to the front of the box,
and when fully back the catch 64 (Figure 7) being pressed against the
rest 65, fixed at the back of the box by the spiral springs 66, falls into
the holes 67, Figure 10, thereby keeping the box back, Figure 7. When

page_text: the box is to be let forward the pin 68, connected with the inclined plane 69,
is pushed back, which throws down the catch 64, and the box is pressed
forward by the spring 70, Figure 10, fixed to the back of the lathe at 71.
When the inclined plane has pushed down the catch it is thrown back into
its original position by the spring 73, fixed to the back of the lathe at 74.
These pins may be pushed back in the same way as already described with the
belt, or they may come against a square cylinder 83, Figure 7, instead of the
stationary plate 11, Figure 1. This cylinder 83, Figure 8, has eight pins 84,
which bring up plates or cards, as Figure 9, which regulate the shifting of the
box. The slots 82, Figure 10, are in the bottom of the box. When the shuttle
enters the slot is pressed against the pin 75, Figure 11, which, pushing down
the lever 76 (working on the stud 77) at 80, lifts it at 78, which lifts the
tongue of the protector 79.
Having thus described the nature of my Invention, and the manner in which
the same is to be performed, I would state that I do not confine myself to the
precise details, so long as the peculiar character of my Invention be retained.
But what I claim is,―
First, the mode of shifting two or more boxes, lifting and falling perpen-
dicular to the race of the lay, and also the method of working the slots, as
described. And,
Secondly, I claim the arranging of the horizontal shifting box moving
with the lay, with slots and apparatus for lifting the protector underneath
the box, and also the shifting the horizontal box, as described.
In witness whereof, I, the said William James Walker, have hereunto
set my hand and seal, this First day of May, in the year of our Lord
One thousand eight hundred and forty-eight.
