SHUTTLE FOR WEAVING CLOTH.

Specification forming part of Letters Patent No.

1,485, dated January 31, 184e; ,Reissued May 3,y

T0 all whom it may concern Be it known that I, JAMES BALDWIN, of Nashua, 'in the county of Hillsboro and State of New Hampshire, have invented a new and useful Impro-vement in Shuttles for lfeaving Cloth; and I do hereby declare that the following is a full and exactdescription thereof.

In the description of said invention reference is had to the accompanying drawings which are made a part of this specification.

In Figures 1, 2 and 3, A A A is the body of the shuttle, Fig. 1, being a longitudinal section of the shuttle, Fig. 2 a view of the bottom of the shuttle and Fig. 3 a perspective view.

In Figs. 1 and 2, B B is the spindle on which the bobbin is placed, in the position which it occupies when turned down into the mouth of the shuttle, being the position occupied by the spindle when the bobbin is placed in the shuttle and the shuttle is in operation in the loom. This spindle plays or turns on the pin P which passes through the body of the shuttle (Figs. 1 and`3) and also through the head D (Fig. 1,) of the spindle.

In Fig. 3, E E represents the spindle turned up out of the mouth of the shuttle in the position to receive the bobbin and the bobbin placed upon it.

In Figs. 1 and 2, C S is a steel spring let into the body of the shuttle on its under vside as shown in Fig 1, and confined to the body of the shuttle by means of the screw IV, Figs. 1 and 2, and this spring presses against the head D Fig. 1, of the spindle at the point H forcing up the rounded end' H of the head of the spindle against the body of the shuttle at I and holding the spindle firmly in its place when turned down into the mouth of the shutt-le and preventing it from playing loosely on the pin P. The dotted lines E E in Fig. 1, indicate the position of the spindle when turned out o-f the mouth of the shuttle for the purpose of receiving the bobbin. The bobbin being placed upon the spindle it is turned down into the mouth of the shuttle the head D of the spindle revolving on the pin P from the position indicated by the dotted lines until the rounded end of the head strikes against the body of the shuttle at I, the body of the shuttle being dug out or hollowed out so as to receive the head of the spindle and admit of its thus turning on the pin. The

of the bobbin striking against the lip or catch S is thus prevented from sliding on the spindle when turned down into the mouth of the shuttle. bin is shown at X, Fig. 3, and the head may be constructed with a groove as there represented into which the lip or catch S, Fig. 1, will pass as the bobbin is turned down .into the shuttle, and they confine it on the spindle. In Fig. 4, which is a longitudinal section o-f the spindle with the bobbin upon it in the position which they occupy when turned down into the shuttle, is shown the manner in which the bobbin `is thus coniined, T T being the head of the bobbin with a groove therein at O, O, and t-he lip S on the end of the spring projecting up into the groove. The spindle being in the position represented by the dotted lines E E, Fig. 1, ready to receive the bobbin. It is placed upon the spindle by the operative and as it is turned down into the mouth of the shuttle the bobbin being pressed down against the head D of the spindle, the lower edge of the head of the bobbin passes inside of the lip or catch S so that the lip or catch S shuts into the groove when the bobbin is turned entirely downinto the mouth of the shuttle as is represented in Fig. 4 and the bobbin is confined in its place. When it is desired to take the bobbin from the spindle, the spindle is turned up out of the mouth of the shuttle and as it rises the rounded end H of the head of the spindle is turned down and forces down the spring into theposition indicated by the dotted lines in Fig. 4, the lip or catch S being carried down by the the bobbin or so as to withdraw itself from the groove O O Fig. 4, and admit of the bobbins being taken-from the spindle.
