NEEDLE-LOOM.

SPECIFICATION forming part of Letters Patent No. 383,079, dated May 15, 1889.

Application tiled .April 15, 1887. Serial No. 234,971. (No model.)

To all whom. it may concern.'

Be it known that I, ALBERT LoUrs SKINNER, of Yonkers, county efl/Vestchester, and State of New York, have invented an Improvement in Needle-Looms,of which the following description, in connection with the accompanying drawings, is a speeiiication, like letters on the drawings representing like parts.

This invention has for its object te improve the class of looms described in United States Patent No. 330,070, granted to me November 10, 1885, by providing the same with a weft stop-motion, which becomes effective to stop the loom in ease the weft or filling thread breaks o1' is not correctly supplied.

In accordance with my invention I have provided the loom,near the shuttle containing the selvage-thread, with an arm or feeler, against which, as the weft carrier or needle moves into position to pass the loop of weft thread over the upturned pointof the shuttle, the weft-thread,when contained in the needle or carrier, is pushed, the said weft-thread acting to turn the said arm or feeler, and through intermediate mechanism,to be described, move into inoperative position a device which, if

i not thus 1noved,would be acted upon to release the shipper-handle, and thus effect, in usual manner, the stopping of the loom. In the said patent I have shown and described a shuttle having a long thin tail, along which the weftthread slides as it leaves the heel of the shuttle, the said tail guiding and delivering the said loop of weft-thread to the feed ot' the cloth. In practice this long thin tail has been found objectionable because of its lack of strength; so te obviate this objection and insure the formation of a perfect uniferm selvage at that side of the fabric where the double shot ef weft is locked by the selvagethread, I have provided the shuttle with a rigid arni,whicli is extended from its heel,the said arm having a delivery-point, the arm cooperating with an arm -holder, the function and purpose of which are to prevent the weftthread as it is passing along the said arm from drawing the said arm and the shuttle longitudinally toward the selvage, for if the said arm were free to be drawn toward 'the selvage to any appreciable degree the selvage would not be straight and uniform.

My invention consists, essentially, in the combination,with a weft carrier or needle and shuttle to lock its thread, of an arm or feeler against which the weft is pressed by the nee dlejust as the weft-thread is to be lecked by the thread carried by the shuttle, substantially as will be described; also, in the combination, with a weft carrier or needle, a shuttle-box, and a shuttle having a rigid arni provided with a delivery point,ofa holder to engage the said arm outside the shuttle-box, whereby a perfect selvage may be made, substantially as will be described.

Other features of my invention will be herein described, and claimed at the end of this specification.

Figure l is a partial front elevation of a sufficient portion of a loom, taken in connection with my said patent,to enable my present invention to be understood, the feeding-roll of the takenp mechanism and the breast-beam being partially broken out te show parts behind them. Fig. 2 is a tcp or plan view of Fig. 1, with ,howeve'r, more of the needleeslide, the central part ofthe loom being broken out to save space on the drawings. Fig. 3 is a righthand elevation of Fig. 2. Fig. 4. is alefthand elevation of Fig. 2. Fig. 5 is an enlarged top view of the shuttle-box, shuttle, and armhelder removed from the loom; Fig. IG, arighthand end elevation ofFig. 5; Fig. 7, a view of the shuttle Aand its arm; Fig. 8,a section of Fig. 5 in the line m4,# Fig. 9, a detail, to be described, referring to the tension device to nip the weft-thread as it is to be pushed against the feeler; and Fig. l0 is a detail showing the weft-thread stretched across the end of the needlehT to act against and turn the feeler.

Referring to the drawings, the loom-frame A, lay B, camshaft C, needle N, carriage E2, to which it is attached, the connecting-rod D5, the lever D2, represented by full lines and operated from the cani D, through the link D"t and lever D', (shown by dotted lines in Fig. 3,) the slide E, on which the carriage is reciprocated, the bracket E', the shuttle bed or boX T, the bracket T', on which it is made adjust able, the projections tt of the shuttle bed or box, the rigidguide-plate T2, the pivoted guideplateT'`,bothhavingattheir upperendsflangcs, under and between which pass the needle N, and the shuttle S, with the exception of its long thin tail, the weft-clamp consisting, essentially, ofa fixed jaw, j, having guiding-eyes for the weft-thread attached to the slideway E, plate F, and a lever, F, for putting tension on the thread, and pivoted at It, are all as in my said patent, wherein like parts are designated by like letters, so that the said parts need not be herein further specifically described.

The cam D, herein shown as toothed at its periphery to form a gear, derives its motion from a small pinion, D3, on a driving or power shaft, D, having usual loose and fast pulleys, D10 D12.

The driving-belt (not shown) is extended through an eye in the arm D13, forming part of a shipper mechanism, the said arm being attached to a rod, D, free to slide in suitable guides, as D15 and 2. The rod D14 has projecting from it suitable pins, 3, (see Fig. 1,) which form a notch, in which enters an arm, D16, on the rock-shaft D", supported in suitable bearings at the loom-side, the said rock-shaft having attached to it the shipper-handle D18, which enters a notched lever-holding plate, D, attached to the loomfside.

The drawings show the shipper-handle in the position it will occupy when the loom is running.

The bracket T has at its under side suitable ears (see Fig. 1) to receive a short shaft, a, to which is secured the arm7 or feeler7 a3, as I shall call it, of the stop-motion mechanism, the said feeler rising through a slot in the said bracket and through a slot, a, of the shuttle bed or box Tsecured thereto,thesaid feeler standing opposite the upturned point of the shuttle S, so that the needle N, as it is about to pass the weft-thread w over the upturned beveled or diagonally-placed pointZ of the shuttle, will J cause the weft-thread held between the eye o and open fork o to be borne or pressed against the feeler and turn it and the rock-shaft a. Whenever the feeler is so pressed back by the weft-thread, the loom will continue to move; but in case the weft is absent and does not push back the feeler the loom will be stopped,

as will be described. Just at the time that the weftthread meets the feeler, as described, the weft-thread is checked or subjected to an extra nip or tension, so that the weft-thread when it comes to the said feeler will be checked for an instant, so that it cannot rend through the tension device. To effect this nipping of the threads the tension-lever F is acted upon by a spring-arm, b2, mounted upon a stud, Z1, of the plate F, attached to the slidewayE. One end of the said arm b2 has joined to it a rod, b4, which is extended along the slideway E to a point inside the loom-frame where the said rod is provided with an arm, b5, and as the carriage E2 arrives nearly at its farthest inward movement it strikes the said arm b5 and turns the spring-arm b2, causing it to travel along in contact with the lever F', thus iucreasing the tension on the weft-thread, the said arm and its actuating devices constituting a tension-increasing device.

The rock-shaft a2 has depending from it an arm, a6, to which is pivoted a rod, al, having at its inner end a loop or eye, as, which rests upon an arm, a9, of a rock-shaft, al", having a second arm, a, provided with a linger, (see dotted lines, Fig. 2, and full lines, Fig. 1,) which is extended behind the shipper-handle D.

In practice the friction of the shipper-handle in the notch 10 of the plate D19 is sufficient to enable it to normally keep the inner end of the arm a lifted, and also to enable it to sustain the weight of the loop a.E and rod of. The loop a8 has extended through it a rod, a, having near its upper end ahook (see Fig. 1) and a pin or projection, 16. r[he rod a is jointed to one end of a lever, a, on a short rock-shaft, al, having its bearings in a stand, a", the said rock-shaft having au arm, als, provided at its end with a suitable lug or projection,which is acted upon, in succession, by one of the pins al, Fig. 3, (see dotted lines,) attached to the inner side of the cam D, there being, as herein shown, three such pins, for the cam D is made to actuate the needle N three times during each rotation of they shaft C.

If the weft-thread is present in the needle, as in Fig. l0, and acts upon the feeler a3 to turn it and push the loop a@ to the right,vicw ing Fig. 1, just as the hook-rod al* is pulled down, as described, then the outer end of projection 20 of the loop will be carried out from the path of movement ofthe hook, so that the loop will not be struck by the hook and the arm a will not be depressed; but should the feeler not be pushed back bythe weft, theu the hook of the rod a will, iu its descent, strike the loop a", and through it depress the arm a and effect the release of the shipperhandle from its holding-notch in the plate D1, enabling the rod D17 to be turned in usual manner to move the shipper to transfer the usual driving-belt upon the loose pulley, or to effect the stopping of the loom or its driving power.

The shuttle S at its heel has attached 'to it a rigid arm, d, having a discharging-point, 24, and a shoulder, 25, a neck, 26, falling between the shoulder and point. a hole in an arm-holder, S2, attached to asuitable guide, S3, attached to the loom-frame.

The shoulder 25 of the shuttle-arm rests against one side of the arm-holder, and,coop erating therewith,prevents such movement of the shuttle or arm-holder as would result in the formation of an uneven selvage, as would be the case were the arm or extension flexible, as in the shuttle described in the said patent. rFhe feeding-roll e, over which is led the woven carpet after passing beyond the breastbeam-such a feedingroll as is ordinarily used in looms for weaving Moquette and other carpetsmhas at one end a toothed gear, e', which The neck 26 enters ICO IIO

ISO

engages a pinion, attached to the hub of a ratchet-wheel, e3, free to be rotated on a stud, e", *extended from the loom side, the said ratchet-wheel being engaged and moved step by step by a pawl, e5, adjustably attached to an arm, e", of arockvshaft, el, having its bearings in a suitable stand,e, secured to the loomside, the said rockshaft at its opposite end having an arm, e", to which is adjustably attached by a stud, ew, a connecting-rod, ew, which at its upper end is adj ustably attached to an arm, ci, secured to the rock-shaft of the lay B, the pawl being moved in unison with the lay and rotating the ratchet-wheel to effect the take-np of the carpet or other material being woven.

The detent e, weighted at one end, engages the wheel e3 and prevents retrograde motion thereof, the pawl e5 being normally held pressed toward the ratchet-wheel e3, so as to elngage its teeth by means of a suitable spring, e a.

The stud e4, at the lefthand end oi the loom, has mounted upon it a pawl-eontrolling lever, el, one end of which embraces the pawl e5, the upper end ofthe said lever proj ecting,as shown in Fig. 4, above the breast-beam, where it has a handle, as c, which may be grasped and moved by the operator in the direction of the arrow against the spring e, and held in the notch ci, (see Fig. 4,) when it is desired to stop the operation of the pawl e5 and ofthe take-up, as is frequently neeessary-as, for instance, when a wrong row of tufts has been inserted or other error has been made in the weaving.

When the loom is stopped, as described, the take-up is permitted to turn backward to enable the feed of the fabric to be brought into correct position for the insertion of the next pick. This may be readily done whenever the pawl e5 and detent e are disengaged from the ratchet-wheel. The loom herein described is provided under the breast-beam with a rod,fl, which slides in suitable bearings, the said rod being surrounded by a spring, asfs, which acts against the loomside and against a collar, as f4, (see Fig. 1,) the spring normally acting to force the rod toward the shipper-handle.

The operator can move the lever el to disengage the pawl e5 from the ratchet-wheel e3 only when the loom is stopped, and in moving the lever in the direction of the arrow upon it in Fig. 4 its upper arm is brought immediately opposite the end of the rod f2, so that when the loom is again started the operator, by taking hold of the shipper-handle D18 and moving it in the direction ofthe arrow immediately above it in Fig. 1, causes the said shipper-handle to act against the end of the rod f2, forces the said rod in the direction of the arrow 30, (see Fig. 1,) compresses the spring f3, and causes the end of the rod just back of the upper arm ofthe lever e16 to force the said lever out of the holdingnotch et", thus permitting the spring e15 to resume control ofthe pawl e5 and draw it `toward and into engagementwith the ratchet-wheel es, the pawl in its movement also turning the lever em, so that its upper end travels in a direction opposite to the arrow 32. that the movement of the shipper-handle to start the loom also throws into operative engagement the devices for operating the takeup, so that the latter will be correctly started whenever the loom is started.

I have omitted from the drawings many parts which are fully shown in the patent referred to, which parts will be used in connection with the parts herein described.
