Application filed February To all whom it may concern:

Be it known that I, CHARLES H. Mourns, a citizen of the United States, residing at VVoonsocket. 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.

The present invention relates to an improvement in shuttles. In the Comisky Patent No. 1,201,150, dated October 10, 1916, is shown and described a shuttle provided with a pivoted spindle carrying a sleeve on which the bobbin quill is supported, which sleeve is resiliently secured to the spindle so that when the shuttle is suddenly arrested at the end of its flight, the bobbin may come to rest with less violence owing to the interosition of a spring between the spindle an the sleeve upon which the bobbin quill is carried.

The object of the present invention is to improve the construction of a shuttle having a resiliently held quill supporting member, and to such end the present invention consists in the shuttle hereinafter described and particularly defined'in the claims.

In the accompanying drawings illustrating the preferred form of the invention, Fig. 1 1s a top plan view of a shuttle with'the 36 spindle holder shown in horizontal section; Fig. 2 is a. longitudinal vertical elevation partly in section; and Fig. 3 is a transverse section taken on the line 3-3, Fig. 1. The shuttle body 1 has the usual bobbin recess 2. The spindle 3 is of the split resilient type, and is provided with a flange 4 integral therewith or securely fixed thereto. The spindle pintle 5 is received in a spindle block 6 pivoted on the pin 7 in the shuttle body. .In normal position, as shown in Fig. 2, the spindle block rests upon the transverse pin 8, bein held thereagainst by the spindle block spr1ng9, which is supported on the two transverse pins 10 and 11 carried by the shuttle. These parts are received in the spring recess 12 in the bottom of the shuttle body. The spindle block 6 is provided with a spring cup 13 which is a cylindrical cup-like member formed upon 24, 1923. Serial No. 621,034.

the spindle block. A strong, shock-absorb ing spring 14; is received in the spring cup and engages at one end the flange 4 of the spindle and at the other end the spring follower 15, which is screwed into the mouth of the spring cup, being provided with two spanner holes 16 by which it may be screwed in. When the spring follower 15 is screwed home against the shock-absorbing spring 14 it compresses that spring and thereby holds the flange 4 of the spindle yieldingly against the bottom 17 of the spring cup 13. The spindle pintle 5 is permltted to move long)- tudinally in the spindle block 6. An oil hole 18 is provided for lubricating it. The spindle pintle5 is provided on its under side with a slabbed portion 19 which engages the surface of the pivot pin 7 and thereby holds the spindle from turning in the spindle block.

When it is desired to put a bobbin in this shuttle the spindle 3 is grasped by the hand and lifted out of the bobbin recess, thereby turning the spindle on the pivot 7 and lifting it up so that it projects upwardly from the bobbin recess at an angle. This pressure is resisted bythe spring 9, but by turning the spindle far enough the corner 20 of the spindle block is brou ht into a. line from the center of the pivot? perpendicular to the surface of the spring 9, so that the spindle is thereby held in its lifted position. The bobbin quill is then thrust on the spindle 3 and the spindle is pressed downward to enter the bobbin recess in which it is held by the spindle spring 9. Upon a shot of the shuttle to the left, as viewed in Figs. 1 and 2 of the drawings, the bobbin and spindle are cushioned by the pressure 'of the flange 4 against the shock-absorbing bobbin s ring, thereby bringing the, spindle and bob in to rest with greater easethan otherwise would be the case, and contributing to the good operation of the thread in the shuttle.

Having thus described the invention, what is claimed is:

1. A shuttle having, in combination, a body provided with a bobbin recess, a spindle block provided with pivot pin and spindle holes, a pivot for the spindle block supported in theshuttle body, a transverse stop pin supported in the shuttle body and adapted to engage the side of the spindle block to limit its movement, the spindle block being also provided with a. spindle cup. :1 flat coil spring in the spring cup, 8, spring follower closlng the mouth of the spring cup and engaging the base of the spring. the spindle provided with a spindle pintle received in the spindle hole in the spindle block and with a flange engaging the bottom of the spring cup on one side and the small end of the spindle spring on the other. a spindle hloek spring supported in the shuttle body. said spindle block being provided with a rain surface to engage the spindle block spring at a point such as to muse the spindle block to tend to turn toward and to engage and press upon the transverse stop pin as the spindle is turned to weaving position.

2. A shuttle having, in combination, a body provided with a bobbin recess, a spindle block having a spindle lole and a, spring cup, 20

a pin upon which the spindle block is pivoted to the body. a, spindle having a'pintle received in the spindle hole and having a slabhed surface engaging with the pin to preventturning of thespindle, a flange on the spindle, and a spring within the spring cup and pressing on the flange to hold the spindle in position.
