LOOM FOR WEAV ING CH EN l LL-E WEBS.

SPECIFICATION forming part of Letters Patent No. 470,426, dated March 8, 1892. Application filed May 23, 1889. Serial No. 311,771. (No model.)

To @ZZ wir/0112, t may concern.-

Be it known that I, RICHARD HARTLEY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new anduseful Improvement in Looms for 'WeavingChenille Webs, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in looms more particularly designed for weaving chenille webs, the same embodying means for bringing the yarn of the required color into position to be grasped and carried by the shuttle.

It further consists of the combination and arrangement of parts hereinafter set forth.

Figure l represents a front view of a loom embodying my invention. Fig. 2 represents a side elevation thereof. Fig. 3 represents a section on line @o on, Fig. 2, on an enlarged Fig. 4 represents a vertical section of a detached portion on line ,e e, Fig. 3, on an enlarged scale. Fig. 5 represents an end View of a guide or eye employed. Fig. 6 represents a perspective View of the guide-shown in Fig. 5. Fig. 7 represents a detail view of parts, illustrating diagrammatically the operation of the weft-gripping devices or shuttles. Fig. 8 represents a vertical sectional view of the parts shown in Fig. 7. Fig. 9 represents a vertical section on line y y, Fig. l. Fig. l0 represents an end View of one of the shuttlejaws. j

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, 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 L and are connected with the 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 series of pivoted elbow-levers M, which are arranged in an arc of a circle and have bearing or resting upon their horizontal limbs the movable pins N, which are vertically arranged in the guides P, projecting from the sides 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 movable 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 Fig. 4:. To prevent the easy displacement of the heads from the armsk B, the walls of the openings in the said arms are provided with projecting portions RX, which enter 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 SV 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-boltslT, 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 Afilling-yarn against the base of the eye, 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.,wl10se lower ends are pivoted to the levers Z, which latter are engaged by cams A', secured on the drivingshaft VX, 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 theloonl-frame.

The side arms or swords C of the lay C are pivoted at their lower ends to the arms H2, which are pivotally secured to the frame of the loom, said arms riding on cams D on the driving-shaft VX, and to the lay are secured the pitmen C2, which are connected with the crank-shaft DX, journaled in the frame A, whereby the proper motion is inuparted to the lay, so that it may properly beat up the fabric, the said mechanism causing the lay to move in a horizontal direction instead 'of the usual arch; but such'form of construction for connecting the lay and operating the same is old andwell known and not claimed per se herein.

E designates the shuttle race, extending across the lay of the loom.

The shuttle F' (shown in Fig. 7) has the spring-jaws H andJX, normallyclosed, 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 lilling-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 H' and has raised end portions, be-

tween 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 Warpthreads of the shed to pass between theshuttle and the carrier as the carrier, with the shuttle, is shot across the loom in the groove Gr of the shuttle-race. Pivotally connected with the shuttlerace and adjacent to the sides of the loom are the pairs of cam-heads J', J2, J 3, and J4, said heads being normally held against the stop-pins L on the shuttlerace by the springs K' and adapted to engage the Shanks F of the jaws of the shuttle inthe 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, either to release the thread which has passed through the shed or to clasp the thread which is to be passed through, 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 H', which may be of any suitable material, as catgut, dac., passes around the pulleys M on the lay and then around the guide-pulleys N' 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 Fig. l.) Bearing against the said strap R on opposite sides of the pulley Q are the rollers S', which are journaled on the upper ends of Each of the latter' is pivotally the rods T'.

connected to thefront end of a lever U', 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 laterall y-proj ectin g pin V2, which is engaged b v a cam-arm V', secured to and rotatable with the driving-shaft lxrythe said arms V' being on opposite sides ofthe shaft'VX, so as to alternately contact with their respective pins V2, and th ns draw down the rods T and rollerS' with the cord R', thereby imparting oscillating motin to the wheels Q and P', and therebymoving 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 clearlyshown in Fig. l.

The lower end of each of the frames K is arc-shaped and rides on anti-friction rollers A2, whose bearings are on spring pressed stems B2, fitted on the sides of the frame, the saidvrollers 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 f openings S on both sides of the loom,as seen in Fig. l. 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 elbowi lever M, and thereby lifting the pin N, with which said lever engages.

As the cam J oplerates the lever H and rod F, and consequently the arms D and links C O, the arms B B are moved toward the center' of the box or frame K, as seen by the dotted lines, Fig. 2. rlhe selected pin N, being in the path of motion of the heads R,is now engaged by theV .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 JX, which was'held opened by contact with the heads J', is released therefrom, vso that it closes, grasping the filling-thread. As the shuttle comes in contact with the outer pair of cams J2 on the opposite end of the race, the jaw JX, which holds the filling, is opened, so that the latter is released therefrom, while at the same time the other jaw l-IX is opened by contact with the cams J4, so asto be adapted to grasp another illingthread. As the shuttle starts to return, the removal of the jaw H from the cam-heads .l4 permits the latter to close and grasp the thread, so that the shuttle carries it through the shed and across th e race, when it is released IOO IIO

from the said jaw HX by the contact of the camheads J2 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 by the shears described 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.

Itis 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 inl contact with the pin N as raised, and thus moves the boX or frame K to the required extentV 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, advances in opposite directions toward the center ot' the boX or frame K, and thus comes in contact with any pin N that may be in the path of the heads R inl the grooves Q, such pin being properly raised, so as to be engaged by the head of either of the arms B, the box o1' 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 ofany suitable form.

The particular form of shuttle and carrier described herein is not claimed7 forming per Se no part of` this invention, as any other suitable operative shuttle or carrier therefor can be employed in connection with the other parts of the loom.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,'is y l.
