FOR WEAVING."-A communication from abroad by John Bailey, of

PROVISIONAL SPECIFICATION left by the said Clinton Edgcumbe Brooman
at the Office of, the Commissioners of Patents, with his Petition, on the
11th December 1866.
I, CLINTON EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and
Company, of 166, Fleet Street, in the City of London, Patent Agents, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING," to be as follows:-
This Invention consists of a new "taking-up motion" in looms for weaving,
and consists of the following mechanical arrangements:-On the usual or
ordinary cloth beam of a loom 1 key or otherwise fasten a toothed wheel,
which is driven by a worm working into the teeth of the wheel. The worm
is mounted upon the loose part of a catch box in such a manner as to admit
of the loose part of the catch box having a lateral movement and a back-
ward and forward rotary motion, taking the worm with it in its backward and

page_text: forward rotary motion only. On the end of the loose part of the catch box
and fastened to it is a small disc to be used as a handle, so that the weaver
can ungear the catch box whenever it is necessary to "let back
or "draw up,"
(that is, to let or take cloth from or to draw or take cloth on to the cloth
beam.) The loose and fast parts of the catch box are held in gear by a
spring, and are mounted and fastened upon a shaft, which is held in its place
in the following manner:-To the side of the loom is screwed or bolted a
bracket with two projecting arnis; one end of the shaft passing through a
step which swivels in one of the arms, and another part of the shaft lying in
an open slot in the other arm. The shaft is also partially embraced by the
end of one arm of a bell-crank lever which holds the worm and toothed
wheel in gear; the fulcrum of the bell-crank lever works upon a stud screwed
or fastened to one of the projecting arms of the bracket; the other arm of the
bell-cranked lever forms a handle, held in its place by a catch screwed to the
press beam" of the loom. The object of the handle and lever is to admit
of the weaver's uncoupling the worm and toothed wheel on the cloth beam at
any time, or when it is necessary to take the "cut" or cloth from the beam;
the said shaft has also mounted loosely upon it a quadrant wheel, upon the
side of which are mounted catches which work in the teeth of a ratchet wheel
keyed upon the aforesaid shaft, and upon the end of the aforesaid shaft is keyed
a break pulley, partially round which is wound a chain, the ends of which are
loosely screwed to any convenient part of the loom, so that any inaccuracy
through vibration or by the wheel slipping back may be prevented. Working in
the teeth of the quadrant is a rack held in its place by a bracket bolted to the
side of the loom, in which bracket is a slot, so that the rack working in the
slot can have imparted to it a reciprocating rectilinear motion. The rack has
made with it or fastened to it a nib or projecting bit, under which works one
end of a lever; the fulcrum or other end of the lever works upon a stud
screwed to a bracket bolted to the side of the loom, or to the back rail of the
loom; screwed to the loom is a stud, upon which works a friction bowl,
which rests upon a cam or excentric keyed to the tappet shaft of the loom.
I now proceed to explain how the above-mentioned parts of the Invention
receive their various motions:-The tappet shaft of the loom carries round
with it the cam or excentric, giving to the lever an upward movement, and
the lever by means of the nib or projecting bit takes with it the rack, both the
lever and rack following the cam or excentric in their downward movement by
their own weight or gravity; the rack gives to the quadrant wheel a recipro-
cating motion, and the quadrant wheel by means of the catches imparts to the
ratchet wheel an intermittent rotary motion, thereby communicating a like

page_text: motion to the shaft, catch box, and worm, and the worm gearing into the teeth
of the wheel upon the cloth beam gives a like motion to it also, thereby
taking or winding the cloth upon the cloth beam.
As the above mechanical arrangements and motions give only a regular
intermittent rotary motion to the cloth beam, and not a progressively slower
motion which is required as the cloth increases upon the cloth beam, I
proceed to explain how that motion is obtained, or, in other words, how
one definite speed at or of the circumference of the cloth upon the cloth beam
is maintained. Parallel with the cloth beam and resting upon it is a rod or
bar, the ends of which work in slots in two brackets bolted one to each side
of the loom, or to the "press beam," so as to allow the rod or bar to rise as
the cloth increases upon the cloth beam. Attached to the rod or bar is
another rack, the teeth of which work into the teeth of a pinion wheel, which
is made with or fastened to a half heart wheel, and the half heart wheel having
teeth upon its periphery gears into a curved rack which lies alongside, and is
connected with a movable inclined plane; or instead of the half heart' wheel
having teeth upon its periphery it can be made without teeth, in that case a
chain takes the place of the curvéd rack, one end of the chain being attached
to the outer extreme point of the balf heart wheel, and the other end of the
chain being attached to a standard fastened to or made with the base of the
movable inclined plane; the movable inclined plane is hinged to its base at
one end, and the other or raised end is fastened to the standard, which is made
so that the movable inclined plane can be set and held at different gradients;
the base of the inclined plane slides in a slot made in a fixing screwed or
bolted to the front rail of the loom, and by which the movable inclined plane
is held in position. Attached to the first-mentioned rack and parallel with it
is a screw, on which works a nut with a projection made upon it, which pro-
jection as the rack descends falls upon the movable inclined plane, so that the
person working the loom can by turning the screw give the first-mentioned
or "thicker
rack a greater or less fall, thereby making the cloth "thiuner
as required, and by giving the movable inclined plane a greater or less gradient
accordingly the cloth is maintained at one thickness throughout the piece, the
use of change wheels or pinions being thereby obviated; but change wheels or
pinions can also be used with this Invention. In that case I introduce between
the worm and the wheel upon the cloth beam an intermediate wheel so
arranged as to allow the wheel upon the cloth beam being changed without
interfering with the position of the cloth beam.
$5
I now proceed to describe how the above-mentioned parts are affected by the
increasing of the cloth upon the cloth beam. As the cloth increases upon the

page_text: cloth beam it raises the rod or bar, the rod or bar taking with it the rack which
is attached to it, and the rack gearing into the pinion attached to the half heart
wheels draws them round, and the half heart wheel by means of the curved
rack or chain draws the movable inclined plane under the projection of the
nut, which works upon the screw attached to the first-mentioned rack, thereby
stopping the descent of the first-mentioned rack sooner, as the movable inclined
plane is drawn more or farther under the projection of the nut, or as the cloth
increases upon the beam.
Another part of this Invention consists of an arrangement for stopping the
action of the foregoing taking-up motion the moment the "setting-on rod" of
the loom is thrown out of gear. For this purpose I attach to one end of a
rod or bar a wedge, the other end of the rod or bar I attach to the end of a
lever, having its fulcrum upon a stud screwed to a bracket bolted to the loom
side, or the stud can be screwed to the loom side without the bracket; the
other end of the lever works in a slot formed for that purpose in the "setting-
on rod." The working of this part of my Invention is as follows:-When
the "setting-on rod" is thrown out of gear it takes with it one end of the lever,
the other end draws with it the bar or rod drawing the wedge between the
small disc fastened upon the loose part of the catch box and one of the pro-
jecting arms of the bracket which holds the shaft and other parts in their
position, thereby uncoupling the catch box and stopping the cloth beam.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Clinton Edgcumbe Brooman in the Great Seal Patent Office
on the 11th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CLINTON
EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of December, in the year
of our Lord One thousand eight hundred and sixty-six, in the thirtieth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Clinton Edgcumbe Brooman, Her special licence that I, the
said Clinton Edgcumbe Brooman, my executors, administrators, and assigns,
or such others as I, the said Clinton Edgcumbe Brooman, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein

page_text: 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," (com-
municated to me from abroad by John Bailey, of Forssa, Finland,) upon the
condition (amongst others) that I, the said Clinton Edgcumbe Broomau, my
executors or administrators, by an instrument in writing under my, or their,
or one of 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 I, the said Clinton Edgcumbe Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings bereunto annexed,
that is to say-
This Invention consists primarily of a new or improved "taking-up motion"
in looms for weaving, and applies to power looms whether used for plain
or fancy work.
The main features of the Invention are, firstly, the mechanical arrangement
of certain parts in such a nanner as to admit of their motions or speed being
intercepted or decreased; and, secondly, in the arrangement of other parts so
as to intercept or decrease those motions or speed by and in proportion as the
cloth increases upon the cloth beam, so that as the diameter of the cloth
and beam increase the circumference is maintained at one definite speed.
These arrangements are fully explained hereafter, and are represented
in the accompanying Drawings in which like letters denote like parts. These
Drawings show those parts of a loom to which the Invention is applied, no
material alteration is required in the loom except that of taking away the
taking-up motion previously in use.

Invention applied to an ordinary loom side.
Figure 2 is a plain view taken through the line A, A, of Figure 1.
Figure 3 is a section of a "swivel step" showing its position in a section
of one end of the bracket a.
Figure 4 is part of the plan view showing the position of the change wheel
or pinion when adapted to and used with this Invention.

fication of this Invention, particularly the arrangement of the rod or bar k
with its curved arm, also the section of a wheel V₁ and the horizontal
rack V³.

its curved slot, and the brackets Y and Y" which hold the roller p in its
position.
Figure 8 is another part of the back sectional elevation shewing another
modification of this Invention.
Figure 9 is a front elevation of parts of a loom showing an arrangement for
stopping the action of this taking-up motion at the moment the "setting-on
rod" of the loom is thrown out of gear.
And Figure 10 is a top view of Figure 9 showing the projecting arm k¹
attached to or made with the rod or bar k, also a plan of the catch n.
I now proceed to describe more particularly the various parts and arrange.
ments of this Invention. On the "gudgeon" of the ordinary, cloth beam i
of a loom I key or otherwise fasten a toothed wheel j (the teeth of which
are not shewn in the Drawings), which gears into and is driven by a worm e
which is held in its position by part of the bracket a, and is mounted upon a
part d of a catch box in the following manner (see Figs. 1 and 2):-The two
screws or pins s¹, s¹, are screwed fast in the worm e, their ends entering two.
longitudinal slots in the part d of the catch box; on the end of this part d
of the catch box is fastened the small hollow shaft or tube g, to which is
firmly attached the disc f; the part d of the catch box is mounted loosely,
Within the small hollow shaft
and the part c is fastened upon the shaft b.
or tube g and shown by dotted curved lines is a spiral spring held in its place
by a washer, and the set screw m¹ which is screwed into one end of the shaft b;
the object of the spiral spring is to push and hold the parts d and c of the
catch box in gear. The above arrangement allows the weaver (by taking
hold of the disc f) to overcome the pressure of the spring and uncouple the
catch box without altering the position of the worm e, but by turning the disc f
either to the right or left it takes the worm e with it, thereby winding on or
"letting" cloth off the cloth beam. The shaft b is held in its position by the
following means :-To the side C of the loom is bolted the bracket a which
has two projecting arms; one end of the shaft 6 passes through a step z¹, which
swivels in the end of one of the arms (shown in section in Figure 3), and
another part of the shaft passes through an open slot in the end of the other
arm; the shaft is also partially embraced by the end of one arm of a bell-
erank lever m, the fulcrum of which works upon a stud r which is screwed

page_text: to one of the projecting arms of the bracket a, the other arm of the bell-crank
lever terminates with a haudle, and passes through the catch n which is
bolted or screwed to the "breast beam" O¹; thus by taking hold of the
handle of the bell-crank lever m, and releasing it in the catch n, the worm e
will be uncoupled from the toothed wheel j, leaving the cloth beam i at liberty
so that the "cut" or cloth may be readily taken from the loom. The shaft 6
has also mounted loosely upon it a quadrant or section of a wheel p, upon
one side of which is screwed or bolted a bracket t (see Figures 2, 5, and 9),
to which are fixed studs, upon which are mounted the catches U, U, U, that
take into the teeth of the ratchet wheel Q which is keyed on the said shaft b..
The catches are held to their places by the small springs T, T, T. Upon the.
end of the shaft 6 is keyed a break pulley R partially round which is wound
a chain S, one end of which is screwed to the loom side C, and the other end
is screwed to a spring St which is bolted to the loom side C. The object
of the break pulley R and the chain S is to hold the shaft 6 at rest
during the descent of the lever G, and to prevent any inaccuracy through or
from vibration. Gearing into the teeth of the quadrant or section of a
wheel p is a rack u held in its position in the following manner :-Bolted to
the loom side C is a bracket or fixing M, in which is a perpendicular slot,
through which pass the ends or a stud from each of the bracket N which'.
are fastened to the rack u, in such a manner that it and the bracket N are
held in a perpendicular position and can have imparted to them a reciprocating
rectilinear motion. The rack u has made with or fastened to it a projection v,.
under which works the end of the lever G, the fulcrum or other end works
upon a stud F which is screwed to the bracket E bolted to the loom side C;
screwed to the lever G is a stud I, upon which works a friction bowl H resting.
or working upon a cam or eccentric K which is keyed upon the tappet shaft L.
of the loom.
บ
I now proceed to explain how the above-mentioned parts of the apparatus.
receive their motions. The tappet shaft L carries round with it the cam or
eccentric K, giving to the lever G an upward movement, the end of which.
lever coming under the projection takes with it the rack u and the bracket N.
The rack u and the bracket N follow the cam or eccentric in their downward
movement by their own weight or gravity. The rack u gives a reciprocating.
motion to the quadrant or section of a wheel p; this by means of the
catches U, U, U, imparts to the ratchet wheel Q an intermittent rotary..
motion, thereby communicating a like motion to the shaft b; the catch
box d, c, and the worm e, which gearing into the toothed wheel j gives to it:

page_text: a like motion, and through it to the cloth beam i, thereby taking or winding
the cloth upon the cloth beam.
As the above mechanical arrangements and motions produce only a uniform
or regular intermittent motion or speed, and not a gradually decreasing
motion or speed which is required as the cloth increases upon the cloth beam,
I will now explain the mechanical arrangements I make use of for that
purpose. Parallel with the cloth beam i and resting upon it is a rod or bar k,
the ends of which are held in slots in the brackets 1, 1, (Figures 5 and 9,)
which are bolted to the loom sides C and C³, the slots in the brackets allowing
the rod or bark with its projecting arm k¹ to be raised as the cloth increases
upon the cloth beam. Screwed to the projecting arm is a rack W, the
teeth of which gear into the teeth of the pinion X which is made with or
connected to the half heart wheel V, to the extreme end or point of the half
heart wheel is attached one end of a chain S", the other end being attached
to a curved standard Z' which is made with a piece Z, which forms the base
of a movable inclined plane q; one end of this inclined plane passes through a
slot in the standard Z' and terminates with a screw, upon which is a nut, by
means of which it can be set and held at any required gradient or angle, the
other end being hinged to its base Z for that purpose. The standard Z' has
attached to it a strap or flexible band x, to which is attached the weight y to
prevent the movable inclined plane q from being drawn unduly forward by
the weight of the chain S". To the base Z are screwed two studs w, w,
passing through a slot in a ledge upon which the base rests; the ledge is made
with or fastened to the bracket Y, which is bolted to the front rail D of the
loom. In some cases I make the half heart wheel with teeth upon its
periphery which gear with a rack fastened to and lying alongside the base Z,
and so curved that it will bo in gear at all times with that part of the half
heart wheel which points downward. Now in the bracket N and held by
it is a screw O, on which is a nut P made with a projection and screw upon
it, the screw passing through a slot in the bracket N has a nut upon it by
which it is screwed firmly to the bracket N at any required elevation. The
rack w, the bracket N, and the screw O descending by their own weight or
gravity, the projection on the nut P falls upon the movable inclined plane q.
Therefore the rack w will have a greater or less fall as the nut P is screwed
or set higher or lower on the screw O. The front edge of the bracket N has
a graduated scale upon it which indicates the correct elevation for putting
in the cloth, any given number of "picks" required, thus enabling the weaver
to make the cloth "thinner" or "thicker," and by setting the movable

page_text: inclined plane at a greater or less gradient accordingly, which is indicated on
another graduated scale upon the front edge of the standard Z', the cloth
will be maintained at one thickness throughout the "piece." The use of
change wheels or pinions is by these means entirely obviated. But change
wheels or pinions can be used with this Invention, as will be better under-
stood by reference to Figure 4. To the bracket a is bolted the bracket a³,
which has in it a slot, so that the bracket all which is bolted to it can be
moved either backward or forward when it is necessary to change the
wheels. The worm e I take from the part d of the catch box and fasten it
upon the stud or shaft 6', on the end of which I fasten the change wheel 2 in
the ordinary manner gearing into the wheel 1, which is mounted upon the
part d of the catch box in place of and in the same manner as the worm e
which has been before described, the cloth beam i and the toothed wheel j
being so arranged that the teeth of the wheel j will work in the worm e as
before. The ends of the stud or small shaft 6 pass through slots in the
bracket al, and this stud or shaft is held in position by pins 4, 4, so that by
taking out these pins, the change wheel 2 can be taken out of gear from the
wheel 1 and the worm e from the toothed wheel j, thereby letting the cloth
beam at liberty, so that the "cut" or cloth can be taken from the loom, as
in this case the bell-crank lever m is dispensed with. In order to change the
wheel or pinion 2 I loosen the bolt which holds the brackets all and a³
together; I then take away the change wheel 2 and replace it by another,
moving to and fixing in such a position the bracket a" upon the bracket as
that the change wheel newly put on will gear into the wheel 1 as before. I
also move the tooth wheel j upon the "gudgeon", so that it will again gear
into the worm e.
I will now explain how the increase of the cloth upon the cloth beam effects
the above mechanical arrangement, so that as the diameter of the cloth and beam
increase the circumference is maintained at one definite speed. As the cloth
increases upon the cloth beam i it raises the rod or bar k with its projecting
arm k¹, taking with it the rack W, which draws round the pinion X and the
half heart wheel V, which by means of the chain S draws forward the movable
inclined plane q, and in proportion as it is drawn under the projection of the
nut P the rack u has a shorter stroke or descent, thereby communicating less
motion to the cloth beam as the cloth increases upon it, and if care is taken
to have the half heart wheel V made of the right form, and the movable
inclined plane q set at the gradient required, the circumference of the cloth
and beam, or the cloth upon the beam will be maintained at one definite
speed.

page_text: Another part of this Invention is an arrangement for stopping the action of
this "
taking-up motion" the moment the "setting-on rod" of the loom is
thrown out of gear (see Figure 9). For this purpose the thin part of a wedge
his placed between the disc f and one end of the bracket a, and is held in
position by resting upon a ledge formed on the bracket a for that purpose;
made with or attached to the wedge h¹ is a rod h, the end of which is hinged
to one end of a lever f; the fulcrum of this lever turns upon a stud g¹ screwed
to the bracket d¹ which is bolted to the loom side C¹; the other end of the
lever has a stud upon it which enters a slot made for that purpose in the
"setting-on rod" e¹ of the loom. The lever f¹ is made sufficiently elastic to
enable the weaver to take the stud out of the slot and to hold the catch box
d, c, uncoupled, by which means a few "picks" or a little cloth may be
"let back" without going to the other side of the loom to uncouple the catch
box by means of the disc f.
The working of this part of the apparatus is as follows:-When the
"setting-on rod "e is thrown out of gear it takes the position shewn by the
dotted lines 5, taking the lever f¹ to the position shown by the dotted lines 6,
and draws with it the rod h, so that the thick part of the wedge h¹ is drawn
between the small disc f and the end of the bracket a, thereby uncoupling the
catch box d, c, and stopping the action of the taking-up motion.
I now proceed to describe a modification of this Invention. According to
this modification, by means of the brackets c¹, c", (see Figures 9 and 10,) the
cloth beam i is raised about one inch and half, and the other parts accordingly,
to allow space for the cloth upon the cloth beam, and instead of the bar k,
with its projecting arm k¹, the brackets 1, 1, the rack W, the pinion X, the
balf heart wheel V, and the chain S, I use the following arrangement (see
Figures 6 and 7):-Along the rear side of the cloth beam i and parallel with
it is a rod or bar k", with its curved arm held in its place by the slotted
brackets 1, 1, which are bolted to the loom sides C and C¹ (in the places of
the brackets i, ¹). The roller p" with its curved slot is fastened upon a stud
or small shaft y', upon one end of which is keyed the section of a wheel V₁
which gears into a horizontal rack Vs. The stud or small shaft y¹ is held in
its position in the following manner :-One end of it passes through a step in
the bracket Y, and the other end passes through a step in the bracket Y"
which is bolted to the bracket Y for that purpose.
The action of this modification is as follows:-As the cloth increases upon
the cloth beam i it pushes from it the rod or bar with its curved arm "",
the end of which enters and moves in the curved slot of the roller p", giving
to it a rotary motion and taking with it the section of a wheel V' which

page_text: gearing into the horizontal rack V draws the moveable inclined plane q further
under the projection of the nut.P.
The following is another modification of this Invention:-I take away the
break pulley R, the chain S", the spring S¹, the quadrant or section of a
wheel p, the rack u, the bracket M, the bracket N, with the screw O and nut
P, the half heart wheel V, the bracket Y, the small pinion X, and the movable
inclined plane q, with its base Z and standard Z', and instead thereof I use
the following arrangement (see Figure 8):-Inside the bracket a is screwed
or bolted a bracket S, to which are attached studs, upon which are mounted
the catches U, U2, which take into the teeth of the ratchet wheel Q. On
the shaft 6 is mounted loosely the section p¹ which has made with it a nib or
projection p, and has fastened to it the small springs T, T, T¹, and the
studs upon which are mounted the catches U¹, U, U To the projecting
arm k¹ is screwed one end of the rack W¹, the other end passes through a
notch Ys made with the bracket Y. The teeth of the rack gear into the
teeth of the small pinion X', which is made with or fastened to the.cam or
scroll V; these work together upon a stud 6 screwed to the bracket Y';
which is bolted to the front rail D of the loom.
:
The following is the action of this modification:-The lever G working
under the nib or projection p takes with it the section p', and this by means
of the catches U', U', U', gives motion to the ratchet wheel Q during the time
the lever G is rising, but during its descent the ratchet wheel Q is held at
rest by the catches U², U. Now as the cloth increases upon the cloth beam i
it raises the rod or bar k with its projecting arm k¹ which by means of
the rack W¹ draws round the pinion X and with it the cam V", thereby
shortening the stroke or fall of the section pl as the thick part of the scroll is
drawn under the nib or projection p¹¹. It must be observed that the cam Vu
can only be employed when change wheels are used, as it is not susceptible
of alteration, as is the case with the movable inclined plane q, in the place of
which it can be used. The other parts of this modification can be used either
with or without change wheels, as also the modification shown by Figures 6
and 7.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,-
Firstly, the rack and the arrangement, substantially as described, for
holding it in such a position that its descent or motion can be intercepted or
decreased.
Secondly, the movable inclined plane q, see Figures 5 and 9, and the cam

page_text: or scroll V, Figure 8, for the purpose of intercepting or decreasing the
descent or motion of the rack u, or the section p¹, substantially as described.
Thirdly, the catch box d, c, and the manner of mounting the worm e or
the wheel 1 upon it, and the arrangement for uncoupling it for the purpose
of enabling the weaver to "let back" or "draw up," that is, take cloth from
or wind cloth upon the cloth beam, all substantially as described.
Fourthly, the screw P. and the nut O, for the purpose of enabling the
weaver to regulate or make the cloth "thicker" or "thinner," without the use
of change wheels or pinions, substantially as described.
Fifthly, the manner of adapting change wheels to the new or improved
taking-up motion, substantially as described.
Sixthly, the modification, substantially as described and shewn at Figures 6
and 7, with the peculiar form of slot in the roller p", and the method described
and shewn of drawing forward the inclined plane q....
Seventhly, the use of graduated scales for indicating the relative positions of 1
the nut P and the movable inclined plane q, and for the purpose of enabling
the weaver to change the quantity of "picks" to be put into the cloth,
substantially as described.
Eighthly, the apparatus or mode, substantially as described, of stopping the
action of this taking-up motion the moment the "setting-on rod "e¹ of the s
loom is thrown out of gear.
Ninthly, the general arrangements and combinations of parts, substantially
as herein-before described and shown in the accompanying Drawings.
In witness whereof, I, the said Clinton Edgcumbe Brooman, have here-
unto set my hand and seal, this Tenth day of June, One thousand eight 2
hundred and sixty-seven.
