'BOBBIN-HOLDING' MEANS.

Application filed June 29,

T 0 (ZZZ whom it may concern Be it known that 1, WILLIAM P. WOOD, a citizen of the United States, residing at 34 Brook St, Pawtucket', in the county of Providence and State oil? Rhode Island, have invented certain new and useful Improvements in Bobbin-l-Iolding Means; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bobbin holding means for loom shuttles.

Bobbins used in loom shuttles, and more particularly those used in the shuttles of weft replenishing looms, are made of wood and are usually formed with a projection at the butt having ribs or shoulders which are engaged by a tongue on a bobbin catch carried by the shuttle body. lVith this construction, the wooden ribs are frequently split oli by the constant hammering due to the travel of the shuttle back and forth and the sudden starting and stopping of: the shuttle, thus delaying the weaving and rendering the bobbin unfit for further use. Considerable loss is occasioned in this way and various kinds of bobbin holders have been devised, but they have not been success ful in preventing injury to the bobbins.

The object this invention is to prevent such wastage of bobbins and loss of time in the weaving by providing improved bobbin holdin means -for more securely holding the bobbin in the shuttle during the weaving.

To this end the bobbin is held in the shut tle by means of interlocking metallic holding devices, one or more members of which are on the shuttle and one or more cooperating members of which are on the bobbin. The holding devices preferably comprise spurs or fingers arranged to lit within metallic or reinforced sockets, and the spurs are preferably formed on a spring catch plate secured to the shuttle, while the reiniorced sockets are preferably formed by embedded metallic bushings in the butt of the bobbin, since this enables the strain on the bobbin member to be more evenly distrib uted and more effectively withstood.

Referring to the drawings, Figure l is a view'partly in side-elevation and partly in Specification of Letters Patent. Patented July 26, 1921.

1918. Serial No. 242,673.

longitudinalsectionof a portion of a shuttle, with a bobbin occupying its normal or operative position therein, and showing a preferred form or" the lnvention; Fig. 2 IS a similar view showing the bobbinspindle elevated to release the bobbin; Fig.3 is a bot spindle through which the pivot pin passes has two angularly disposed positioning faces E and F on its under side, adapted to cooperate with a spring member to hold the bobbin spindle in its two extreme positions; one being the normal or operative position, and the otherbeing the bobbin receiving and releasing position. The parts so far described are of usual construction.

The bobbin holding means comprises two fingers or spurs 7 projecting upwardly from a spring catch plate 5 which is secured to the shuttle by the screw 6, and which may also form the spring member cooperating with the spindle positioning "faces E and F. The spursare arranged to engage reinforced sockets 11 formed by inserting metallicbushings 10 in holesbored in a longitudlnal tongue 8 which extends'diametri'cally across the butt end of the bobbin G, and is formed with two parallel fiat surfaces 9. The tongue is of sufiicient thickness to allow the central longitudinal opening H in the bobbin to continue therethrough. The socket holes are bored transversely through the tongue at'right angles to the surface 9,

one at each side of the central. opening H V which receives the spindle B. The metallic bushings are inserted in the holes and the ends are rolled over on to the opposite fiat surfaces 9 of the tongue so as to hold the bushings securely in place, and also strengthen the tongue aboutthe bushings. Reinforced sockets are thus formed which ily be engaged with the spurs oft-he catch.

The bobbin is first placed on the spindle while the latter is in its receiving position, I

as shown in Fig. 2, and as it is swung downwardl toward its operative position, the spurs on the bobbin catch enter the sockets 11 in the tongue. Inasmuch as the sockets extend through the tongue, the spurs on the bobbin catch may enter them from whichever yarn carried by the bobbin.

When the spindle and bobbin are finally positioned, as shown in Fig. 1, the spurs 7 project practically their entire length into the sockets and securely hold the bobbin against longitudinal displacement on the spindle, and also position it with the 'teeler hole I in proper relation to the replenish ing mechanism. The strain resulting from the sudden stopping of the shuttle during the weaving is resisted by the bushings which are firmly seated within the wooden tongue of the bobbin, so that they will effectively resist the strains and shocks to which they are subjected without danger of breaking the tongue or of becoming detaChed therefrom.

While the invention has been herein described and illustrated by the drawings in accordance with what is now considered to bethe preferred'embodimentthereoi, it will be understood that changes in the form and arrangement may be made without departin from the spirit and scope of the claims,

Ilaving described the invention, what is clanned 1s 1. In a shuttle, the combination with the bobbin and the bobbin spindle, of a longitudinal tongue at the butt end of the bobbin having a socket extending transversely therethrough, and a spur on the shuttle body adapted to engage said socket when the bobbin is inserted to lock the bobbin against longitudinal displacement or turning on the; bobbin spindle.

2. In a shuttle, the combination with the bobbin and the bobbin spindle, of a longi tudinal tongue projecting from the butt end of the bobbin having sockets extending transversely therethrough, and bobbin. holding means on the shuttle'body adapted to codperate with said sockets to hold said bobbin against longitudinal displacement in the shuttle and positively prevent the bobbin from turning on the bobbin spindle.

3; In a shuttle, the combination with the bobbin and the bobbin spindle, of a longitudinal tongue at the butt end of the bobbin having a transverse recess therein, a bushing in said recess, and a bobbin catch on the shuttle body having a spur adapted to enter said bushing when the bobbin is inserted in the shuttle to lock the bobbin against longitudinal displacement or turning on the bobbin spindle. a

4:. In a shuttle, the combination with the bobbin and the bobbin spindle, of a longitudinaltongue at the butt end of the bobbin having reinforced sockets extending transversely therethrough, a bobbin catch on the shuttle body, and spurs projecting from said bobbin catch adapted to enter said sockets to lock the bobbin against longitudinal displacement or turning on the bobbin spindle.

'5. In a shuttle, the combination with the .bobbin and the bobbin spindle, of a longitudinal tongue at the butt end of the bobbin having recesses extending transversely therethrough, bushings in said recesses, a plate secured at one end of the shuttle body, and spurs projecting from the opposite end of said plate and adapted to enter said bushings when the bobbin is inserted in the shuttle to lock the bobbin against the longitudinal dis placement or turning on the bobbin spindle.

6. In a shuttle, the combination with the bobbin and a pivoted bobbinspindle having positioning faces at its pivoted end, 01 a tongue projecting longitudinally from the butt-of the bobbin and having holes extending transversely therethrough, bushings in said holes, a spring plate secured at one end to the shuttle body and adapted to cooperate with said positioning faces to hold said bobbin spindle in operative and inoperative positions, and spurs on said plate to engage said bushings when said bobbin spindle is swung into operative position to lock the bobbin against longitudinal displacen'ient or turning on the bobbin spindle.

7. The combination in a shuttle having a pivoted bobbin spindle with positioning faces formed at its pivoted end, of bobbin catch comprising a spring plate secured at one end to the shuttle body, and adapted to cooperate with said positioning faces to hold said spindle in two positions, spurs on said plate, and a bobbin adapted to be inserted on said spindle when said spindle is in one position and provided with sockets in the butt thereof adapted to be engaged by said spurs when the spindle is in the other position to lock said bobbin against longi tudinal displacement or turning on said spindle. 1

8. A wooden shuttle bobbin having a tongue across its buttlend provided with reinforced sockets extending transversely therethrough and adapted to be engaged by bobbin holding prongs on a shuttle.

9. A wooden shuttle bobbin having a tongue across its butt end provided with two transverse holes, and bushings in the holes having their ends rolled over theitaces of the tongue.
