Improvements in Looms for Weaving.
We, RICHARD HARTLEY, of 2117 E Tioga Street, Philadelphia, Pennsylvania,
Inventor, HENRY FOULDS, Gentleman, and ALBERT FOULDS, Shoe Dealer,
both of 3428 Frankford Avenue, Philadelphia, Pennsylvania, all of the United
States of America, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
n and by the following statement :-
Our invention consists of improvements in looms, more particularly designed for
weaving rugs, but applicable to carpets, hangings and other fabrics of the order
of chenille, the same embodying means for bringing the yarn of the required
shuttle into position to be grasped and carried by the shuttle.
It further consists of the combination and arrangement of parts hereinafter set
forth.
In the accompanying drawings,

Figure 10 represents an end view of one of the shuttle jaws.
Similar letters of reference indicate corresponding parts in the several figures.
A designates the frame of the loom, on the upper portion of the sides of which
are mounted the swinging arms B, which depend from their axis and are connected
with their links C, the latter being attached to the arms D on the studs E on the
frame A.
F designates rods, whose upper ends are pivoted to the arms G on the studs E;
and whose lower ends are pivoted to the levers H, which are pivoted on the lower
portion of the frame A, and bear upon the cams J secured to the driving shaft V*,
suitably journalled in the lower part of the said frame A.
K designates swinging frames which depend from each side of the upper portion
of the frame A, and are mounted on the axis or shaft L, on which the arms B are
mounted. Each of the said frames K is provided with a series of pivoted elbow
levers M, which are arranged in an arc of a circle, and have bearing or resting
upon their outer horizontal limbs the movable pins N, which are vertically
arranged in the guides P projecting from the side of the frame K. It. will be
readily seen that the movement of the elbow levers M, will either raise or lower
the said pins.
In the sides. of the said frames K are circular grooves or ways Q, having
novable within them the elastic heads R, which are fitted in openings in the lower
ends of the arms B, and project therefrom, as shown in Figure 4.
To prevent the easy displacement of the heads from the arms B, the walls of the
openings in the said arms are provided with projecting portions R*, which enter

page_text: grooves in the heads so that when the latter are sprung or forced into the openings,
they are reliably held thereon.
The lower portion of each frame K is provided with a series of openings having
therein the eyes S, arranged in circular form, and through which the ends of the
filling threads or yarns are passed.
In each of the frames K above the eyes S, are the screw bolts T, having their
heads in the slot U of the frames, and their points bearing against the walls of the
eyes S, so as to keep the latter in place.
Pivoted to the inner side of each of the eyes S, is a dog or pawl V, having a
tooth W on its lower side adapted to press the filling yarn against the base of the
cye. and thereby prevent it from slipping from the eye.
On the sides of the loom frame A are secured the shears X, the movable blades
of which are connected with the rods Y, whose lower ends are pivoted to the
levers Z, which latter are engaged by cams A' secured on the driving shaft V
whereby the shears are opened their closing motion being effected by means of
the springs B attached to the levers Z, and to proper parts of the loom
frame.
The side arms or swords Cx of the lay Care pivoted at their lower ends to the
arms H2, which are pivotally secured to the frame of the loom, said arms riding on
cams Don the driving shaft V*, and to the upper end of the lay are secured the
pitmans C, which are connected with the crank shaft Dx journalled in the
frame A, whereby the proper motion is imparted to the lay, so that it may properly
beat up the fabric, but such form of construction for connecting the lay and
operating the same, is old and well known, and not claimed per se herein.
E' designates a shuttle race of any usual construction, extending across the loom
and secured or supported on the end portions of the frame thereof.
The shuttle F shown in Figure 7, has the spring jaws H* and * normally
closed, mounted at each end thereof and pivoted thereto, the inner portions of said
jaws being preferably serrated or corrugated to reliably retain a hold on the filling
thread while carrying it across the shuttle-race. The shuttle-carrier G is secured
at its ends to the ends of a chain or band H¹, and has raised end portions between
which the shuttle F is held, the said shuttle having depending anti-friction wheels,
and the carrier having wheels above the top thereof for readily allowing the
lower warp threads of the shed to pass between the shuttle and the carrier, as
the carrier with the shuttle is shot across the loom in the groove G* of the shuttle-
race.
Pivotally connected with the shuttle-race and adjacent to the sides of the loom
are the pairs of cam heads J, J2, J³, and J, said heads being normally held against
the stop pins L on the shuttle-race by the springs K, and adapted to engage the
shanks Fx of the jaws of the shuttle in the travel of the latter across the race, the
said stops limit the movement of the cams in one direction only, so as to afford a
firm bearing when opening the jaws to release the thread which has passed through
the shed, and permitting a free movement in the other direction, so as to allow the
jaws to readily ride over the same without opening, when the filling is to be passed
through the shed.
The chain or band H¹, which may be of any suitable material, as catgut, etc.
passes around the pulleys M' on the sides of the loom frame and then around the
guide pulleys N₁, and a pulley P' below the shuttle-race. On the shaft of the
pulley P is a pulley or wheel Q, around which passes a cord or strap R', the ends
of which are secured to the loom frame, see Figure 1.
Bearing against the said strap R' on opposite sides of the pulley Q, are the
rollers S, which are journalled on the upper ends of the rods T. Each of the
latter is pivotally connected to the front end of a lever U¹, which is pivoted at its
rear end to a cross bar or other portion of the frame of the loom, and is provided at
or near its front end with a laterally projecting pin V, which is engaged by a cam
arm V₁ secured to and rotatable with the driving shaft V. The said arms V₁ are

page_text: on opposite sides of the shaft V*, so as to alternately contact with their respective
pins, and thus draw down the rods T' and roller S' with the cord R', thereby
imparting oscillating motion to the wheels Q and P, and thereby moving the
chain H', so as to reciprocate the carrier and shuttle across the race.
The elbow levers M have their upper limbs connected with the cords W' of any
ordinary jacquard attachment X', the needles Y' and card Z' of which are clearly
shown in Figure 1.
The lower end of each of the frames K are are-shaped and ride on anti-friction
rollers A, whose bearings are on spring-pressed stems B fitted, on the sides of the
frame, the said rollers acting as checks in connection with the corrugated lower end
of the frame for keeping it in place.
The operation is as follows:-
Yarns of different or required colors are inserted in the openings S, on both sides
of the loom, as seen in Figure 1.
The jacquard is now operated so as to place the yarn of the desired color in
position to be grasped by the shuttle. The proper cord W is drawn or raised by
the jacquard, thus operating the attached elbow lever M, and thereby lifting the
pin N with which said lever engages. As the cam J operates the lever H and
rod F, consequently the arms D and links C, C, the arms B, B, are moved towards
the centre of the box or frame K, as seen by the dotted lines Figure 2. The
selected pin N being in the path of motion of the heads R, is now engaged by the
advancing head or heads, whereby the box or frame K is moved the distance
required, to bring the pin to a position coincident with the shuttle race, the yarn
thus being placed in line with the shuttle.
The shuttle which now may be at the right of the race is moved across the
same, the jaw H* thereof leaving or passing the pair of cam-heads J2, which are
readily moved on their pivots, so that the said jaw is not opened while at the
same time the jaw J which was held opened by contact with the head J', is
released therefrom so that it closes, grasping the filling thread. As the shuttle
comes in contact with the outer pair of cams J³ on the opposite end of the race,
the jaw which holds the filling is opened so that the latter is released therefrom,
while at the same time the other jaw H* is opened by contact with the cams J', so
as to be adapted to grasp another filling thread. As the shuttle starts to return,
the removal of the jaw H* from the cam-heads J, permits the latter to close and
grasp the thread, so that the shuttle carries it through the shed and across the race,
when it is released from the said jaw H*, by the contact of the cam-heads .J'
therewith.
When the yarn is carried along by the shuttle, it rides freely under the latch or
dog V, the latter then rising, but when the yarn is cut and the end of the following
yarn hangs from the eye S, the latch or dog falls by gravity, and its tooth W bites
the yarn and holds it against the base of the eye, so that outward or return motion
of the yarn is prevented.
It is evident that the yarn of the desired color may always be placed in position,
to be grasped and carried by the shuttle, this being accomplished by lifting the
relative pin N, by the action of the jacquard, and the intermediate elbow-lever M,
so that when an arm B advances, it comes in contact with the pin N, as raised, and
thus moves the box or frame K to the required extent, in order to bring the eye
that contains the desired yarn in line with the shuttle-race, it being evident that
such operation may be accomplished by the action of either of the arms B, which,
as will be seen, advance in opposite directions towards the centre of the box or
frame K, and thus comes in contact with any pin N that may be in the path of the
heads R in the grooves Q, such pin being properly raised so as to be engaged by
the head of either of the arms B, the box or frame K being thereby moved in a
direction from front to rear of the loom, or vice versa, thus placing the yarn of the
desired color at the proper spot or place...
The mechanism for shedding may be of any suitable form. The particular form
of shuttle and carrier described herein is not claimed herein, forming per se no part

page_text: of this invention, as any other suitable operative shuttle or carrier therefor can be
employed in connection with the other parts of the loom.
