elating to the Picking and Take-up Motions of
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows :-
This invention relates to looms for weaving and comprises the improvements
hereinafter described.
The said invention consists partly in actuating the shuttles of the loom by means
of shuttle grippers and carriers. Each of these consists of a sliding piece that works
in guides extending widthwise of the loom, and a pair of gripper jaws elevated above
the sliding piece, and having grooves adapted to receive the shuttle. One of each
pair of gripper jaws has fulcrummed to it a gripper lever. This lever is fulcrummed
between the ends. One end is provided with a hook or spur and extends into one of the
shuttle grooves, and the other end is provided with a rod that extends down through
the slide piece of the gripper and carrier to which it belongs and into a slot that
extends widthwise of the loom in a gripper lever operator. Motion is transmitted to
the gripper lever operators by means of levers working in cams mounted on the
main shaft of the loom. At the proper times the gripper levers are caused to grip
the shuttle. Motion is transmitted to the shuttle grippers and carriers by other levers
working in other cams mounted on the main shaft. These cams are reversed, so that
when one set of shuttle grippers and their carrier are coming toward the lay the other
set will recede from it and conversely.
Two shuttles may be employed if the shuttle grippers and carriers are severally
provided with a second pair of gripper arms, and one of these arms has fulcrummed
to it a gripper lever operating in conjunction with the rod to which the gripper lever
beneath it is attached.

page_text: My invention further partly consists in means for taking up the woven fabric and
comprising a pair of take-up rollers, upon the shaft of one of which is mounted a gear
wheel, which by means of a clutch may be caused to grip the shaft more or less
tightly.
Motion is imparted to the gear wheel by a pinion mounted on a shaft and having
affixed to it a clutch wheel loosely mounted on the shaft actuated by a clutch. Motion
is imparted to the clutch by a lever affixed to the shaft. A friction brake is employed
to prevent the movement of the clutch wheel in one direction. Motion is transmited
to the lever by a rod actuated from another rock shaft. An adjusting device is
employed by which the length of movement of the lever may be varied.

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents
Southampton Buildings in the County of Middlesex, do hereby declare, the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and, by the following statement:
-
This invention relates to lobnds for weaving and comprises the improvements herein-
after described.
The said invention consists partly in actuating the shuttles of the loom by means of
shuttle grippers and carriers. Each of these consists of a sliding piece that works in
guides extending widthwise of the loom and a pair of gripper jaws elevated above the
sliding piece and having grooves adapted to receive the shuttle. One of each pair of
gripper jaws has fulcrumined to it a gripper lever. This lever is fülcruined between
the ends. Ohe end is provided with a hook or spur and extends into one of the shuttle
grooves, and the other end is provided with a rod that extends down through the slide
piece of the gripper and carrier to which it belongs and into a slot that extends width-
wise of the loom in a gripper lever operator. Motion is transiiiitted to the gripper
lever operators by means of levers working in cams mounted on the main shaft of the
loomi. At the proper times the gripper levers are caused to grip the shuttle. Motion
is transmitted to the shuttle grippers and cartiers by other levers working in other
camis mötinted on the main shaft. These cams are reversed so that when one set of
shuttle grippers and their carrier are coining toward the lay the other set will recede
from it and conversely.
Two shuttles inay be employed if the shuttle grippers and carriers are severally
provided with a second pair of gripper arms; and one of these arms has fulcrumed
to it a gripper lever operating in conjunction with the rod to which the gripper
lever befieath it is attached.
My invention further partly consists in means for taking up the woven fabric
comprising a pair of take-up rollers upon the shaft of one of which is mounted a gear
wheel, which by means of a clutch may be caused to grip the shaft more or less
tightly:
Motion is imparted to the gear wheel by a pinion mounted on a shaft and having
fixed to it a clutch wheel loosely mounted on the shaft actuated by a clutch. Motion
is imparted to the clutch by a lever affixed to the shaft. A friction brake is employed
to prevent the movement of the clutch wheel in one direction. Motion is transmitted
to the lever by a rod actuated from another rock shaft. An adjusting device is
employed by which the length of movement of the lever fiiay be varied.

page_text: In the accompanying drawing Figure 1 is a plan or top view of parts of a loom
embodying my improvement certain parts being shown in section. Figure 2 is a
central transverse section of the same. Figure 3 is a perspective view of one of the
shuttle grippers and carriers and their co-acting parts. Figure 4 is a side view of a
shuttle gripper and carrier illustrating a modification. Figure 5 is a plan of a shuttle
gripper and carrier illustrating another modification. Similar letters of reference
designate corresponding parts in all the figures.
A designates. the reed. It is mounted in the upper end of a frame A' which is
affixed to a rock shaft A*. The reed is. shown as grasped between jaws a a¹, one of
which is operated by a screw or screws a³.
On the rock-shaft A' is affixed an arm A' that enters a groove in a cam A* affixed
to a shaft A, and derives motion from the said cam, whereby the reed is vibrated.
The shaft A has upon one end a bevel pinion 6 which engages with a bevel gear
wheel 6 affixed to a shaft B that constitutes the main shaft of the loom.
The bevel gear wheel 6' is twice the size of the bevel pinion & hence the reed vibrates
back and forth twice during each rotation of the shaft B.
The shaft B may be furnished with fast and loose belt pulleys and if desirable also
with a fly wheel, as shown.
CC designate shuttle grippers and carriers and D designates a shuttle.
Each of the shuttle grippers and carriers consists of a slide piece c that works in guides d
extending widthwise of the loom, and a pair of gripper jaws c¹ elevated above the slide
piece and having grooves adapted to receive the shuttle. One of each pair of gripper
jaws has fulcrumed to it a gripper lever c. This lever is fulcrumned between the
ends. One end is provided with a hook or spur and extends into one of the grooves;
the other end is furnished with a rod c that extends down through an opening c* in
the slide piece c of the gripper and carrier to which it belongs, and into a slot e that
extends widthwise of the loom in a gripper lever operator E.
Each gripper lever operator consists of an L-shaped piece, one limb e¹ of which
extends widthwise of the loom and is provided with the slot e, and the other limb of
which e, extends fore and aft of the loom.
The limbs of the gripper lever operators E work in guides attached to the
under side of a table or platform F forming part of the loom frame. This table or
platform is omitted from Figure 1 in order to more clearly illustrate the parts beneath.
The limbs e¹ are also supported in guides f¹.
G designates levers fulcrumed at one end to the table or platform F, and connected
at the other end by links H to the slide pieces c of the shuttle grippers and carriers CC¹.
Between their ends these levers G are provided with bowls or rollers which enter
grooves in the circumference of cams I that are affixed to the shaft B. These cams
are reversed so that the shuttle grippers and carriers will be moved in the same
directions, one towards the reed while the other recedes from it, and conversely.
There are straight portions of the grooves which provide for dwells.
The two gripper lever operators E are connected to a T-shaped lever J which is
fulcrumed to the underside of the table or platform F, and has its two cross arms
pivotally connected to the gripper lever operators E and its other arm provided with a
bowl or roller working in a circumferential groove in a cam K affixed to the shaft B.
The groove of the cam K is such that at the proper times it will rock the lever J, so
that the gripper lever ³ of one of the shuttle grippers and carriers will be caused
to release the shuttle, and that of the other shuttle gripper and carrier will be caused
to grip the shuttle.
The shuttle will be delivered first from one shuttle gripper and carrier into the other
and so on.
Two shuttles may be employed if the shuttle grippers and carriers are severally
provided with a second pair of arms c and one of these arms has fulcrumed to it a
gripper lever c as shown in Figures 3 and 4. In Figure 4, the gripper lever c® is
shown as fulcrumed upon that one of the arms which is toward the front of the
loom, and is above and forward of the arm c³, and in Figure 3 said lever is shown as

page_text: fulcrumed upon that one of the arms which is toward the rear of the loom, and is above and
parallel with the arm. The gripper lever c may be connected by a link c' with the
rod c as shown more clearly in Figure 4. When the second gripper lever is thus
operated, the shuttle in conjunction with which it operates, will be impelled in the
reverse directions to the other shuttle.
If however, the shuttles are to be impelled in the same directions at the same time
the said gripper levers may be arranged parallel with the others and connected directly
to the rods c as shown in Figure 3.
L designates a cloth beam or roller upon which the woven fabric is taken up. Its
shaft has mounted on it, friction-tight, a gear wheel L'.
The shaft has a collar y affixed to it. A conical collar g' is fitted to the shaft so that
it may be slid along the same a short distance. It is however, engaged with a spline or
splines so that it will always rotate with the shaft. The gear wheel L' bears against
the collar g. The conical collar fits within the gear wheel L'. The outer end of the
shaft is screw-threaded and has a nut applied to it. By forcing the nut farther on
the shaft or moving it nearer the end of the shaft, the collar may be forced more or
less into the gear-wheel and the latter may be secured with a greater or less frictional
grip, to the shaft.
With the gear wheel L' engages a pinion N mounted on a rock-shaft N'. The
pinion N is affixed to a clutch wheel N mounted loosely on its shaft and having a rim
extending from one side. N³ is an arm hung loosely upon the shaft N and having in
one side at the outer end, a notch whereby it is enabled to embrace the rim of the
clutch wheel. This arm where it surrounds the shaft N₁ is much larger than the
shaft, so that it may be lifted independently of the shaft to cause it, by being canted,
to grip the rim of the wheel. It has a projection extending from one side. A bell
crank lever N' is affixed to the shaft N¹. This lever has on one side a projection.
When this lever is rocked in one direction, its projection will act against the projection
of the arm N. Thereupon the arm will be canted so as to grip the rim of the clutch
wheel and subsequently by the continued movement of the lever, motion will be
imparted to the clutch wheel, the pinion N, the gear wheel L' and the cloth beam L.
The movement of the lever in the reverse direction will not effect the clutch wheel, a
friction brake M being employed to prevent this.
The friction brake M consists of a block of wood or other like material arranged to
slide towards and from the side of the clutch wheel along pinsj extending from a
bracket k. A spring having a swiveling connection with a screw m and working in
a tapped hole in the bracket k, may be caused to force the block M with more or less
force against the clutch wheel to prevent it from turning backwards.
The lever N has a longitudinal slot in its lower arm. A stud O passes through this
slot, is shouldered on one side of the slot and provided with a clamping nut on the
other side thereof, hence it may be secured in different positions to the lever. A rod P
pivotally connected at one end to an arm Q affixed to the rock shaft A' and having at
the other end a longitudinal slot through which the stud O passes, operates periodically
to draw the lower arm of the bell crank lever N* rearwardly. The upper arm of this bell
crank lever operates in conjunction with an adjustable screw stop T whereby the
motion of the lever may be regulated. The arm N³ is connected by a spring S to a
fixed part of the loom frame. This spring returns the arm N³ to its normal position
after it has been rocked by the lever N*.
Obviously by adjusting the screw stop T the length of the movement imparted to
the lever N may be-varied.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. The combination with shuttle grippers and carriers C C₁ having gripper arms or
jaws c', of levers G for reciprocating the shuttle grippers and carriers, cams I for
actuating these levers G, gripper levers c³, gripper lever operators E, a lever J,
and a
cam K, substantially as specified.

page_text: 2. In a loom the combination of a reed and supporting frame or lay, a rock shaft to
which the lay is affixed, a cloth beam, a lever for imparting motion to the cloth beam,
