SHUTTLE.

Application filed fune 3, 1909.

To all whom 'it may concern.'

Be it known that l, Josnrn GAoNoN, a subject et the King of England, residing at Fall River, in the county otl Bristol and State of Massachusetts, have invented certain new and useful Improvements in Shuttles, of which the following is a spcciiication.

My invention relates to certain new and useful improvements in shuttles, and it has for its object to provide a means which will prevent the bobbin from flying ont of the shuttle when the bobbin is disengaged troni its locking mechanism, due either to the breaking' of the locking plate or the breaking of the rear end of the bobbin between the groove with which the plate engages and the rear end.

lV ith this and other objects in view my invention consists in certain constructions, combinations and arrangements ot parts the preferred form of which will be iirst described in connection with the accompanying drawings and then the invention particularly pointed out in the appended claim.

)referring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1 is a plan view of a shuttle provided with the preferred forni of my invention; Fig. 2 is a section taken on line 2, 2 of F ig. l, looking in the direction of the arrow; Fig. 3 is a section ot' the front portion of the shuttle, the section being taken on line 3, 3 of F ig. 1, and Fig. i is a section of the rear portion ot' the shuttle taken on line t, 4 of Fig. 1.

5 is the body et the shuttle having the end portions G and 7 and the usual central slot 8, in which is located the bobbin 9. The bobbin is slipped onto a spindle 10 which .is pivoted at one end by a pin or shai't 11 tending crosswise of the shuttle at the end t3. When the shuttle is in its operative position the spindle 10 and the bobbin 9 occupy the position shown in Fig. l, parallel with the longitudinal axis of the shuttle. rltlhe bobbin is then retained in place on the spindle and is prevented from slipping thereon by mean;` of a bobbin catch 12 on a bobbin catch-plate 13, the catch 12 engaging a peripheral groove 14 on the end of the bobbin. The plate 13 is located in a recess 15 at the bottom of the end G of the shuttle, and is held in place by a screw 1G which passes through the plate 12 and into the wood of the end 6 ot' the shuttle. The spindle 10 is retained in its proper operative position shown in F ig. 1

by means ot a bobbin spring' or tongue 1'4". This bobbin spring or tongue is located in a recess 18 in the upper tace of the end G ot the shuttle, and is held therein by a screw 19 which extends through the bobbin spring and screws into the wood et the end G of the shuttle. This screw is adapted to tension the bobbin spring 1T, as said spring is pretcrably slightly arched. The inner end oit this spring cooperates with the head 2O ot the spindle. This head is provided with suitable faces, so that the bobbin spindle may either be held in its position in the shuttle or when thrown out from the shuttle for the purpose ot changing the bobbin. lt will he not-ed that when the spindle is in the shuttle the groove l-it on the bobbin will be engaged by the bobbin catch 12, se that the bobbin is held in proper position in the shut-- tle. lVlien, however, the spindle is moved on its pivot and out ot' the shuttle the groove le on the bobbin will be moved ont of engagement. with the catch 12 and the bobbin will thus be free to be withdrawn. r1`here are several detects in the use of these old and widely known shuttles which involve the construction so tar described. lt in placing a bobbin on the spindle it is not pushed clear down on the spindle, but only partially pushed into place, as often happens with careless operators, the end of the bobbin is brought into contact with the bobbin catch l, when the spindle is returned to its operative position. As result of such carelessness the bobbin catch plate is subjected to strain and it sometimes causes the breaking of the plate or the breaking et the end of the bobbin. Furthermore, even when the bobbin is properly positioned and locked the end otl the bobbin will sometimes break, permitting the bobbin to slide up on the spindle. The result ot' many et these causes with the ordinary form et shuttle is that the end of the bobbin will wedge up on the t'ront end of the slot and jump out of the shuttle, so that it' the bobbin is passing through the shed the warped threads will be broken and the loom must be stopped until the damage is repaired.

ln order to obviate the etiects just enumerated I have formed the end ot the shuttle slet at the end of the shuttle in novel torni, and it comprises the forming of the upper portions of the shuttle adjacent the thread slot 2() leading' to thc thread-guide 21, with the over-hanging walls rlhe over-hanging walls are so positioned at the front end of the slot that when the bobbin is placed in proper position on the spindle and the spindle turned into the operative position with the bobbin catch l2 in engagement with the peripheral groove le, the end of the bobbin will just clear the edges of the over-hanging walls 22, and when the Spindle is forced down in the line of the axis of the shuttle the end of the bobbin will be beneath these walls. From this it will be seen that should anything break in the locking mechanism for the bobbiu so as to permit the same to move longitudinally on the spindle, the end ot the bobbin will pass over the overhanging walls 22 which will operate to prevent the bobbin jumping out of the shuttle and doing damage.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- A shuttle provided with a central slot, a bobbin spindle pivoted at one end of the slot, a spring resting on the bobbin spindle and tending to hold the saine in horizontal or vertical position, a bobbin catch adapted to engage a peripheral groove in the bobbin to hold the bobbin in axial position on the spindle when the latter is in its horizontal position and parallel to the axis of the shuttle7 the opposite end of the slot in the shuttle to that at which the bobbin spindle is pivoted having its side walls extended over the slot so as to form overhangs separated by a central axial opening, which opening decreases in size toward the end of the slot, and having a thread guide mounted transversely of the shuttle with its opening in line with the opening between the overhanging Walls, the space separating the walls being less than the thickness of the end ot the bobbin, said overhanging wallsextending from the front of the slot toward the rear such a distance as to permit the cud of the bobbin to just clear the rear edges` o1c the overhanging walls when the bobbin is properly positioned on the spindle and the spindle is raised but to catch the end of the bobbin if it has moved forward on the spindle and prevent the bobbin and spindle being raised.

In testimony whereof l allix my signature in presence ot' two witnesses.
