LOOM-SHUTTLE.
Specification, of Letters Patent.
Patented Dec. 7, 1920.
Application led September 25, 1920. Serial No. 412,722.
To all 'whom t may concern.'
Be it known that I, WILFRED J. GLADUE, a citizen of the United States, residing at IVoonsocket, in the county of Providence and State of Rhode Island`,vhave invented new and useful Improvements in-Loom- Shuttles, of which the following is a specication. f
This invention relates to means for clamping a bobbin on the pivoted spindle' of a loom shuttle, when the spindle and Vbobbin are operatively located in the chambered body of the shuttle, and for automatically releasing the bobbin when the spindle is displaced, or swung outward from the body.
Heretofore the bobbin has been clamped by a single clamping member arranged to en age the inner side of the bobbin.
`invention has forits object to more rmly clamp the bobbin than heretofore, and is embodied in a shuttle having an inner clamp adapted to engage the inner side of the bobbin, and an outer clamp adapted to engage the outer side of the bobbin, so that the latter is clamped at two diametrically opposite points, the arrangement' being such that when the spindle is inv its operative position, both clamps are engaged with the bobbin, and when the spindle is displaced, both clamps aredisengaged from the bobbin.
Of the accompanying drawings forming a part of this speciiication,`
Figure 1 is a top plan view` of a shuttle embodying the invention.
Fig. 2 is a bottom plan view of the same.
Fig. 3 is afragmentary view, showing a portion of the shuttle body in section, a portion of the spindle in elevation, and a portion of the bobbin by dotted lines, the clamps being engaged with the bobbin.
Fig. 4 is a view similar to a portion of Fig. 3, Showing the spindle partially displaced, one of the clamps being. disengaged from, and the other engaged withthe bobbin.
Fig. 5 is a view similar to Fig. 3, showing the spindle completely displaced, and both clamps disengaged from the bobbin.
Fig. 6 is a section online 6-6 of Fig. 1.A
The same reference characters indicate the same .parts in all of the iigures.
In the4 drawings, 12 represents a loom shuttle body, which may be of any suitable form and construction, and is chambered to contain the spindle 13 and a bobbin 14 on the spindle. I
The spindle is provided with a base 15, mounted to swing on a'transverse pivot pin 16, fixedto the body and passing through the chamber thereof. v
In carrying out m invention I-provide the shuttle with a pair of clamps, an inner clamp 19, and an outer clamp 20, adapted to simultaneouslyl engage notches 17 Aand 18, formed in opposite sides of the bobbin base, one of said clamps 19 beingvcarried by the shuttle body, and the clamp 20` by the spindle base, and clamp-controllingvmeans, including elements carried by the body, and elements carried by the-spindle. base, said means having provisions for simultaneously engaging the clamps with a bobbin when the spindle is in its operative position, and being operable by the displacement of the spindle to disengage lthe clamps from the bobbin.
The construction of the clamps and the organization of the said controlling means are preferably as next described.
The innerv clamp 19 is composed of a spring arm, bearing at one end on the seat 21 formed in the shuttle body, andengaged between its ends by a headed screw 22, fixed to the body. The free end of the vclamp 19 has 'an ear 19a, constituting the acting portion of the clamp, and ladapted to spring lionto engagement with a notch 17 in the bobrIhe body 12 is provided with a fixed stop 23, which is a pin passing through the chamber of the body, and arranged as shown by Fig. 3, to limit the movement of the inner stop toward the spindle 13. The construction thus far described does not differ materially from that employed in single clamp shuttles in commonA use, the clamp 19 being Vadapted to enter a notch in the bobbin when the spindle and bobbin are in'their operative position shownby Fig. 3, the stop 23 confining the clamp -19vaga1nst movement in one direction, so that when the spindle and bobbin are -swung outward, the bobbin notch leaves the stop ear-'19, and the latter is disengaged from the bobbin.-
The yspindle base 15. is provided with an ear 24, which displaces the stop 19 when the spindle is displaced, as indicated by Figs. 4 and 5.
The stop member 23, which has heretofore had only the function above stated, has, in accordance with my invention, anotherV function, said stop constituting an element of controlling means whereby the outer clamp 2O is disengaged from the bobbin when the s indle is fully displaced, as shown The outer clamp 20 is an arm movably mounted on the spindle base 15, and provided at one end with an ear 20a, adapted to the acting/edges-19a and 20a enter a bobbin notch 18, and constituting the acting portion of the clamp. The opposite end of the clam-p is preferably bent to form aguide member 25, in sliding contact with a guiding face on'the spindle base. A stud 26 is Xed to the outer clamp at a point between its ends, and is slidable in a t socket in the "spindle base. A springv27 interposed between the head 26a of-the stud 26 and a shoulder in the spindle base, normally holds the outerfclamp in its bobbinvengaging position, as shown by Fig. 3. y
he arrangement is such that when the spindle is in its operative position, the ear of the outer clamp 20 is held by the spring '27 in position to engage a bobbin notch.
vWhen, thespindle is displaced by being swung outward, the outer clamp remains in yengagementwith the bobbin until the spindle has moved from the position shown by Fig. 3, to that'shown by Fig. 4, so that the outer clamp remains in engagement with the Vbobbin after the inner clamp is disengaged therefrom. V'hen the spindle is moved farther outward from the position shown by Fig. 4, the stud head 26EL abuts against the stop 23, and is moved by the latter against the force of the spring 27, until the outer clamp is disengaged from the bobbin, as shown byy Fig. 5. The clamps 19 and 2O are therefore successively disengaged from the bobbin, the inner clamp being displaced during the movement `of the spindle from the position shown by Fig. 3, to that shown byFig. 4. v l
A`It will now be' seen that I have provided clamp-controlling means carried in 4part by the body 12, andfin part by the spindle base, for simultaneously engaging the clamps with the' bobbin when the spindle is moved to its operative position, and for disengaging the clamps from the bobbin when the spindle is displaced, the inner clamp being preferably disengaged before the outer clamp. Y aid means may be otherwise embodied without `departing from the spirit yof the invention.
'It will be seen by reference to Fig. 6 that of the clamps 19 .and'20 are parallel with each other and eachY extends'crosswise of the shuttle body` vand substantially parallel with the inner or bottomface ofthe latter. This arrangement causes the grooves 17 and 18'.r infthe bobbin base to extend crosswise of the shuttle body when the bobbin is secured. Said grooves are parallel with the sides of the usual feeler slot 30 in the bobbin base so that the clamps hold the'slot'30 in position to register with the feeler slot 31 in one side of theV shuttle body. A shuttle previously equipped with only a clamp 19 may be provided with the additional clamp 20 by providing the body with a spindle carrying the clamp 20, or by connecting the clamp 2O as shown with an ordinary spindle. Thetwo clamps hold the bobbin so firmly that there is no possibility of even a slight rotative movement of the bobbin in the spindle,such as might occur if but lone clampwere em* ployed. Liability of wearing or chipping the base of thebobbin at the ends of the clamp-receiving groove therein, is thuszprevented. Y

Al loom shuttle Vcomprising a chambered body, a bobbin spindle having a base pivoted to the body, a `pair of clamps formed and arranged for simultaneous engagement with opposite sides of a bobbin on the spindle, one of said clamps being carried by the body, and the other by the spindlelbase, andV clamp controlling means carried by the body and by the spindle base, said means having provisions for simultaneouslyY engaging the clamps with a bobbin when the spindle is vin its voperativey position, and being operable by the displacement lof the spindle to disengage the .clamps Yfrom the V bobbin.
