Application filed January 25, 1910. Serial No. 540,063.

T 0 (ZZZ whom it may concern:

Be it known Rana and J .K'MES A. Knxuss, citizens of the United States, and residents of East Greerr ville, in the county of Montgomery and. State of Pennsylvania, have invented a new and Improved Shuttle, of which the following is a full, clear, and exact description.

The object of the invention is to provide A a new and improved shuttle, more especially designed for use in silk ribbon looms, and arranged to tear the filling thread in case the shed is not fully open or clear, owing to extraneous matter causing a tangle of some of the warps. For the purpose mentioned, use is made of a spring-pressed locking device for the quill, and normally inactive, to allow free rotation of the quill, but when an obstruction in the open shed engages the locking device, then the latter is released to lock the end of the quill and thus hold the same against turning, to tear the filling thread, thus stopping further formation of the weave.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the shuttle; Fig. 2 is a transverse section of the same on the line of Fig. 1, and showing the shuttle in position on the open shed; Fig. 3 is a sectional side elevation of the same on the line of F l, the quill spindle and quill being removed; Fig. i is a plan view of the shuttle, parts being in section, the quill spindle and the quill being removed; Fig. 5 is a side elevation of the quill spindle; and Fig. (i is an end view of the spool or quill.

The body A of the shuttle is provided with the usual bow-shaped front portion B, in the opening of which extend the bearings c, C extending angularly from a metal plate C, secured to the body A of the shuttle, the bearing C being fixed to one side of the frontportion B, while the other bearing C is resilient. The bearing C is provided with a recess or dent C for the reception of one end D of the spindle 1), having its other end formed with an angular arm D engaging a correspondin socket (1*, formed in the resilient bearing C the said arm D and the socket C holding the spindle that we, WELLINGTON N.

I against turning. On the spindle D is mounted to turn loosely the spool or quill E, carrying the filling thread E, which after unwinding from the spool or quill passes through the eyes G, G and G and finally through the eye H, fixed in the front portion B of the shuttle body. The eyes G, G are held on the ends of springs G G attached to the front portion B, while the eye G is hung on the front portion adjacent to the eye H, fixed in the front portion B of the shuttle body. A spring brake I held on the plate C, bears in the usual manner against the filling on the spool or quill E, to retard the turning of the latter with a view to prevent the filling from unwinding faster than required.

The ends of the spool or quill E are provided with slots or recesses E, of which the recesses at the right hand end are adapted to be engaged by a locking device, controlled by ext aneous matter on the warp, as hereinafter more fully described. The locking device, as shown, is in the form of a locking bar J, mounted to slide lengthwise in bearings K and K, arranged on the plate 0, the bearing K being elongated to also allow up and down swinging movement of the locking bar J, the other bearing K acting as a fulcrum. The bar J is pressed on in the direction of its length by a spring L, and one end J is adapted to abut against a stop N on the plate C. The other end of the bar J is provided with an L-shaped lockii g arm J (see Fig. 4), guided in a slot C in the bearing C, and adapted to engage a recess E in the adjacent end of the spool or quill a. The bar J is provided with a curved portion or arm J extending normally a short distance (about an eighth of an inch) below the shuttle body A, to thus extend into the path of any tangled warps or other extraneous matter, so that when the shuttle passes through the shed (see Fig. 2), and the arm J 3 comes in contact with the tangled warps or other extraneous matter, then an upward swinging motion is given to the locking bar J, to disengage the end J from the stop N, to allow the spring L to move the locking bar J in the direction of the arrow a, and thus engage the locking arm J 2 with the recess E in the spool or quill E, to hold the same against rotation. When this takes place, the filling thread F is broken and thus further weaving is prevented, as no filling is paid out by the shuttle. The operator now stops the loom, removes the obstruction that caused the tangle, and then resets the locking bar J by moving the same in the opposite direction of the arrow at and abutting the end J against the stop N. On moving the locking bar J in the inverse direction, the spring L is placed under tension, to readily shift the locking bar J in the direction of the arrow a, as soon as the next extraneous matter on the warp P actuates the locking bar J, as above described.

By constructing the bearings C, C and the spindle D in the manner described, the spindle can be quickly removed or replaced, for exchanging empty spools or quills E for filled ones, and by having the arm l) engaging the socket C the spindle D is held against turning. The spool or quill E is preferably provided at both ends with recesses E, to allow of slipping the spool or quillv E in position on the spindle l), to locate either recessed end adjacent to the locking arm J for engagement by the latter.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. A shuttle for looms provided with a locking device normally held in an inactive position, and adapted to be released by obstructions in the shed, to engage and lock the quill against rotation and thus tear the filling thread.

2. A shuttle for looms, provided with a spring-pressed locking bar for locking the quill, the locking bar having a projecting portion for engagement by obstructions in the shed, and a stop for normally holding the locking bar in an inactive position and under the tension of its spring.

3. A shuttle for looms, provided with a quill spindle, having one end provided with an angular arm, a metal plate secured to the shuttle and bearings for the ends of the spindle extending angularly from the said plate, the bearing for the angular arm end being free and resilient and provided with a recess for the reception of the said angular swinging mo\'*ement of arm, the other bearing being tired and provided with a recess for the other end of the spindle to rest in.

4. A shuttle tor looms, provided with a spindle having recessed ends, a locking bar having a locking arm for engaging one of the recessed ends of the said spindle, the said locking arm having a projecting portion for engagement by obstructions 1n the open shed, a stop for one end of the said locking bar to abut against, and a spring connected with the said locking bar.

5. A shuttle for looms provided with a spring-pressed locking bar for engaging and locking the quill, hearings in which the lock ing bar is mounted to slide, one of said bearings being elongated to permit up and down the locking bar, the said locking bar having a projecting portion for engagement by obstructions in the shed, and a stop for normally holding the locking bar in an inactive position and under the tension of its spring.

6. A shuttle for looms provided with a quill having recessed ends, a metal plate secured to the shuttle and carrying the bearings for the quill spindle, one of said bearings being provided with a slot, a locking bar mounted to slide in bearings on sand plate and having a locking arm guided in said slot and adapted to engage a recess in the adjacent end. of the quill, a spring exerting tension on said locking bar in the direction of its length, and a stop on said plate against which the other end of said locking arm is adapted to abut, the said stop hol-d ing the locking bar in inactive position and with the spring under tension, the said locking bar having a projecting portion for engagement by obstructions in the shed.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
