SHUTTLE. p

Application filed my 1o, 1924. serial No. 725,150.

To all whom t may oofrtoevn` Be it known that I, OvrLA J. BENOIT, a citizen of the United States, residing at lVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shuttles; 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. v

The present invention relates to an improvement in shuttles.

The object of the invention is to reorganize and improve shuttles of the removable spindle type, and to this `end the inven- 1 tion consists in theshuttle hereinafter described and particularly dened in the claims. Y

In the accompanying drawings illustrating the preferred form of the invention,

Fig. lis a plan lView of a part of a shuttle embodying the invention; Fig. 2 is a sectional elevation of the saine; and Fig. 3 is a transverse. section onthe line 3`3, Fig. 2.

The illustrated embodiment of the invention is described as follows: The shuttle 10 is provided with the usual bobbin recess 11 to receive the bobbin12. The bobbin is carried by the spindle blade 13 which is received in the opening in the bobbin. The spindle pintle 14 is received in the spindle block 15 andV firmly held in place therein. The spindle blade'is provided ,on its end V with a head 16 which engages thetip of the bobbin and holds the-latter on the spindle. The spindle pintle is rectangular in crosssection, as shown in dotted lines in Fig. 3. The pintle is received` in a correspondingly shaped slot 17 in the spindle block 15. The spindle pintle is provided with lateral bosses 18 which are received in recesses 19 out in the side walls of theslot 17. The bosses en- VVage the end walls of the recesses 19 and old the spindle from longitudinal movement in the spindle block. The spindle block is provided with an offset ear 20 which is provided with a bolt hole to receive the bolt 21 by which the ear is bolted to the shuttle, as shown in Fig. 2. The spindle block 15 is also provided with a second bolt hole which receives the bolt 22 which, together with the bolt 21, forms the means for securing the block in the shuttle body. A Spring Clip 23 iS Provided- Whch fhas .two

arms that project upwardly and embrace thespindle pintle for the purpose of holding it in position in the spindleV block. The arms of the clip are turned toward each other near their ends, and then outwardly from each other at their ends, so as to form a wedgeshaped opening into which the pintle of the spindle may be pressed and which, when the spindle has been pushed down into place, embrace and hold the spindle, as shown in Fig. 3. The spring clip 23 consists of a single piece of wire,'the ends of which form the ends of the clip portion proper, and the doubled portion extends horizontally under the spindle block and around the bolt 22, by which the clip `is securely held in place with respect to the spindle block. The end of the slot 17 extends through to the end of the block 15, so that the end of the spindle pintle may be received in the hole in the spindle block. The spindle pintle not only extends into but through the hole in the spindle block, andthere engages aspring 24 which is a right angle affair, the short end of which extends up over the hole in the end of the spindle block, and the longer portion of which extends under the spindle block, and is provided with a hole which receives the bolt 22.

In operation the spindle is removed from the shuttle by lifting it up', thereby disengaging the spindle pintle from the clip and freeing the spindle from the block. The

exhausted bobbin is then taken oif and the full bobbin put on over the pintle end of thel spindle. Then the end of the spindle pintle is thrust into the hole beyond the recess in the spindle block, and the spindle is turned about its end so as to swing the bosses 18 down into the recesses 19 in the spindle block. At the same time the spindle is pressed in between the arms of the clip, and once the spindle is forced down to its lowermost position, it is securely held in place by the recess in the block, the bosses which are received inthe spindle block, and by the clip. The hole which receives the Vend of the spindle pintle prevents overthrow of the spindle when it is moved downwardly, and the spring 24 affords a resilientfmeans which presses against the spindle rinly to hold it in position. It is to be noted that the end of the pintle is cut so that it is slightly inclined. This conveniences the insertion of a spindle in the spindle block. By cutting off theupperfeorner of the spindle ,end` theIl lower corner of the bosses will start into the recesses 19 without endwise pressure being -e:\:erted on the-spindle. i rlhen as the spindle j-is 'forced downwardinto a horizontal posi- L pintle adapted to be received in' the pint-le recess of =the block, the pintle and` block having co-operating project-ions and rec esses to prevent more than slight, longitudinal,movement of the pintle witlirelal tion :to the block, a spring clip having arms located at the bobbin end oil-the bleek adapt- V ed toV embrace the, spindle and to hold it in position in the block, a` springliaving a portion yieldingly pressed aga-inst the other endioithe pintlev recess, in tlieblock to en-V gage the end 'of' thespindle, the block be- 'Y ing provided with an offset ear, a bolt for lbolting the `offset ear to the shuttle. body, vand a boltfor bolt-ing the main partei the spindle block, the spring clip and ,the spring to the ,shuttlebody 23A shuttle,comprising a body, a spindle blockl provided with a longitudinal recess, a spring clip at the bobbin end of thebloclr and aespringat the otheryend of tliebloek,
