Loom-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 7 53,957, dated March 8, 1904. Application led December 10, 1903. vSerial No. 184,530. (No model.)

To all whom it may concern.-

Be it known that'I, HENRY CT, a citizen of the United States, and a resident of Woonsocket, county ofProvidence, State of Rhode Island, have invented an Improvement in Loom-Shuttles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts,

This invention has for its object the production of a loom-shuttle providedwith means which upon the occurrence of a float in the warp will break the lling, and thereby cause the stoppage of the loom, so that the weaver can correct the fault promptly. The displacement of one or more of thewarp-threads out of the proper plane of the shed is technically termed a float, and they cause overy shots in the cloth, necessitating pick-outs, so that the loom should be stopped upon the occurrence of a iioat before the damage is done.

In the present embodiment of my'invention I `have provided means in the shuttle to catch Aand. part the filling-thread upon the occurrence of a float, and such breakage will of .courseeifect stoppage in an ordinary loom.

The invention is equally lwell adapted for use in an automatic iilling-replenishing loom of rthe feeler type, wherein the lling-fork eifects stoppage of the loom uponl breakage of the filling, as is well known tothose skilled in the art.

I'have illustrated my invention in connec- 4ti'onwith an automatically self-threading l loom-shuttle; but it will be manifest herein- .after that the invention is not in any way restricted to such type of shuttle, as it can be used with equal facility in a common shuttle operated in a non-replenishing loom.

The various novel features of my invention will be fully described in the subjoined specification and particularlypointed out in the following claims.

similar view, but showing theilling about to be parted or broken as the result of the de- Fig. 4 is a top or plan view of the front end of the shuttle. Fig. 5 is a transverse section on the line 5, Fig. 2, looking toward the right; and Fig. 6 is a similar view on the line 6 6, Fig. 3.

The shuttle-body B, having a side deliveryeye bx and a longitudinal opening B to receive the filling-carrier or bobbin BX, is of usual construction and, as herein illustrated, l

is provided with a threading-block T, having a longitudinal thread-passage t and a passage t leading to the eye 6X to automatically conduct the filling-thread tx from the threadpassage to the eye in well-known manner.

On the inner face of the side wall of the shuttle toward which the filling whips or turns as it is drawn oif over the tip of the lling carrier I have mounted a threadparter, which is normally rendered inopera- Upon the occurrence of a oat in the warp, however, the thread-parter is automatically rendered operative to engage and catch the lling-thread between the tip of the filling-carrier and the delivery-eye of the shuttle, the lateral deflection of the thread caused by such engagement preventing it from drawing off the bobbin and breaking it promptly. l

Referring to the drawings, a plate l, having an upright slot 2, is firmly secured to the inner face of the rear side wall b of the shuttle, (the thread drawing off from left to right when vfacing the tip of the bobbin,) the plate having. a wing 3, through which some of the fastenings 4: are extended into the wall, said wing lying against the latter. The upright rear edge of the plate is bent over at 5, and the opposite edge above the wing is similarly bent at 6 to form an upright recess or pocket between the side wall and the plate, behind the slot 2, for a purpose to be described. A prong 7 springs from the bottom of the slot and is curved toward the longitudinal center of the shuttle and upturned, (see Figs. l, 5, and 6,) its tip 8 being somewhat lower than the top of the slot 2 and leaving a clearance between the tip and the plate. If the tip of the prong is exposed or unprotected, the iill- IOO ing-thread will as it whips or throws around the tip of the bobbin pass down between the tip of the prong and the plate 1, as shown in Figs. 3 and 4, and be held from further rotary motion, so that longitudinal pull on the thread will draw it across the filling-carrier and break it promptly. Such lateral deiiection of the thread and the diagonal line of pull thereof across the filling-carrier is so clearly shown in Fig. 4 that the action of the parting-prong 7 will be manifest.

The parting device must be inactive or inoperative under ordinary conditions, but rendered operative to act as described when a float occurs.

In the present embodiment of my invention I have provided a guard to normally shield or hood the tip of the prong and shed the thread therefrom, the guard being mounted on a yielding support, which serves also as a fioatdetector, so that upon occurrence of a iioat the guard is retracted 4and the prong uncovered. A resilient arm 9, preferably made of light yet strong wire, is iixedly secured at its rear end by a pin or other fastening 10 to the side wall the forward end being downturned at 11 to enter the pocket hereinbefore referred to between the bent edges 5 and 6 of the plate 1. The lower end of the bend 11 is shaped to form a guard by forming' two upright parallel loops 12 and 13, connected by the crosspiece 14, the loops projecting through the slot 2 at opposite sides of the prong 7. The resiliency of the support 9 ordinarily lifts the loops forming the guard to the top of the slot 2, Figs. 1, 2, and 5, to thereby shield or hood the tip of prong 7 and shed the thread as it whirls around between the bobbin'tip and the shuttle-eye, the free end of the support being then elevated above the top of the shuttle. When, however, the shuttle in passing through the shed encounters afloat and is therebylifted to make an overshot, the warps above engage and depress the detecting member 9, thereby lowering the guard into the position shown in Figs. 3, 4, and 6 and uncovering the prong 7 to operate as has been described.

If the shuttle passes underneath a float held out of its proper plane in the shed, it will de press the support'9 and move the guard into inoperative position, as before set forth.

Manifestly the means herein shown and described will operate in the same manner if applied to a common shuttle instead of to one provided with an automatic self-threading device.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be modified by those skilled in the art in various particulars without departing from its spirit and scope.

Having fully described my invention, what I claim as new, and desire to-secure by Letters Patent, is-

1. In a loom-shuttle having a delivery-eye and adapted to contain a filling-carrier, a thread-parter located on the shuttle-wall in front and at one side of thetip of the fillingcarrier, a guard to normally prevent engagement of the filling-thread by said device, and a controller for and to retract the guard and render the thread-parter operative upon the occurrence of a float in the warp.

2. A loom-shuttle adapted to contain a filling-carrier and having a delivery-eye, an upturned thread-parter on the side wall of the shuttle and between the eye and the tip of the filling-carrier, a guard to normally shield or hood the thread-parter, and a yielding support for the guard extending above the shuttle and adapted to be depressed by a ioat, to retract the guard, the whipping of the filling-thread causing its engagement and breakage by the thread-parter when the guard is retracted.

3. A loom-shuttle adapted to contain a filling-carrier and having a delivery-eye, an up turned prong mounted on the side wall of the shuttle near the tip of thel illing-carrier, a guard to normally shield or hood it and prevent catching of the filling-thread thereby, and a yielding support for the guard normally extending above the top of the shuttle and adapted to be depressed upon the occurrence of a warp-iioat, to retract the guard and render the prong operative.

4. A loom-shuttle adapted to contain a filling-carrier and provided with an automatically self-threading device, a thread-parter mounted on the shuttle side wall slightly in advance of the tip of the lling-carrier, a resilient iioat-detector carried by the shuttle, and a guard controlled by the detector and normally retained thereby in position to prevent engagement of the filling-thread by the thread-parter, detection of a ioat causing the guard to be retracted and thereby rendering said threadparter operative.

5. A loom-shuttle adapted to contain a filling-carrier and having a delivery-eye, a slotted plate secured to the side wall of the shuttle beyond the tip of the illingecarrier and having an upturned prong, a resilient float-detector mounted on the shuttle and having its forward, free end downturned to pass between the plate and the side wall of the shuttle, and a guard carried by the downturned end of the detector and projecting inward through the slot in the plate, to normally shield the point of the prong and prevent engagement of the filling-thread thereby.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
