SHUTTLE.

Application led March 29, 1923.' Serial No. 628,453.

To ZZ whom t may concern.'

Be it known that I, JOHN C. SnAMBow, a citizen of the United States, residing at lVoonsocket, in the county of Providence and State of Rhode Islan-d, have invented certain new and useful Improvements in Shuttles; and I do hereby declare the ollowing 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.

The present invention relatesto an improvement in shuttles.

The object of the invention is to reorganize and improve the construction of removable blade shuttles, and to this end the invention consists in the improved shuttle'hereinafter described and particularly defined in the claim.

In the accompanying drawings illustrating the preferred from of the invention, Fig. 1 is a plan of the shuttle, showing the end in which the bobbin holding blade is secured; Fig. 2 is a sectional elevation of the same; and Fig. 3 is a transverse section taken on the line 3-3, Fig. 2.

The body of the shuttle is provided with the usualvbobbin recess 11. The bobbin 12 is provided with the base 13 having driving notches 14 for engagement with the usual driving lugs on the spinning frame. It is desirable to hold the bobbin both from longitudinal movement and from rotational move ment in the shuttle, and to these ends the spindle 15 is provided with a head 16 at its end to engage the tip of the bobbin and hold the bobbin from longitudinal movement on the spindle, and one of the notches 14 is adapted to be engaged by a lug on the spindle block 21, pivoted at 22 on the pin 23 in the shuttle, which lug 20 holds the bobbin from rotating in the shuttle. This spindle block is provided with a central longitudinal pintle receiving hole 24 which receives the pintle 25 of the spindle 15. The spindle block is provided with a cam 26 which is engaged by the spring 30, one end 31 of which engages the cam as shown in Fig. 2, the other end 32 of which engages the bottom of the end of the spring slot 33 in the shuttle. A spring bolt 34 holds the spring in place and under tension. The pintle 25 of the spindle is slabbed oi at 35 so as to pass the pivot pin 22, and its end is provided with a transverse recess 36 i is provided with a transverse recess 41I adapted to engage and receive the transverse pin 42 supported in the shuttle body.l The spindle block is cut away at 43 so that when the spindle bloclt is turned down to the position shown in Fig. 2, the pin'42 enters the recess 43 without engagement of the pin with the walls of' the recess. The spindle blade 44 is provided with an enlargement 45 which is slabbed oli' at 46 to permit the spindle pintle to enter the spindle block until the shoulder of the enlargement 45 engages the face of the spindle block without engagement with the projection 20 hereinbefore referred to. In use, when it is desired to remove the bobbin from the spindle, the end of the spindle is lifted, thereby distorting the spring 30 and moving the point of the cam under the end 31 of the spring, so that the spindle block will be held with the spindle inclined upwardly. At this time the spindle is free to be removed from the spindle block; a bobbin may then be dofed and a new bobbin put in place. The operative positions the bobbin on the spindle with one of the notches over the slabbed portion 46, and inserts the spindle pintle in the hole in the spindle block, pushing it down as far as it will go. Then the spindle and bobbin are pushed down into the bobbin recess in the shuttle, and the two recesses in the top and bottom of the spindle pintle receive the two transverse spindle holding pins 40 and 42. 'Ihese pins now hold the spindle both` :trom rotation and from longitudinal movement, and the bobbin is held from longitudinal movement in one direction by the head of the spindle, and in the opposite direction by engagement of the shoulder at the end of the bobbin recess in the shuttle, and it is held 'from rotation by the 'engagement of the projection 20 of the spindle block with one of the recesses in the bobbin base. The spring 30 holds the spindlel block inclosed position, as shown in Fig. 2, by pressure on the top of the cam 26.

It is to be observed that the three pins, namely the spindle block pin and the spindle pintle holding ins, comprise the means for securely hol ing the bobbin in fixed poin both positions by the spring. The Con-` .struotio'n' vis simple', eliioient,r strong ind d`u- Table;

Having V,thus described the inventiom,

what is claimed is:

. A shuttle having, in combination; a, body,

' a spindle block. pivoted in the body and having a bobbin engaging lug to prevent `,rotation of the bobbin and a longitudinal `splindle hole, a, spindle having a; pintle received in the spindle hole and provided VWith an enlargement to form a shoulder iadapted `t0` beai against the spindle block, fthe enlirgementbeing sl'abbed beneath the bobbin en- -gaging lug of the spindle'bloekg'and additional means engaging the spindle to prevent rlongitudinal vmovement vof the latter.
