LOOM-SHUTTLE.
SPECIFICATION forming part of Letters Patent No. 407,958, dated July 30, 1889.
Serial No. 305,660. (No model.)
ing description, in connection with the ac-v companying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its objeetto provide a loom-shuttle with means for clamping and holding firmly upon its spindle one end ot a cop-tube-such as commonly employed upon mule-spindles-thus enabling mule-spun cops to be taken directly from the mule-spindles and be employed economically in loom-shuttles.
In accordance with my invention, the shuttlc-spindle, provided with a shoulder to actas a stop for one end of the usual cop-tube, composed of paper, cloth, -or metal, has combined with ita finger, which, as the spindle is turn ed into the shuttle in position for weaving, catches the cop-tube near its end, clamping the latter between the finger and the spindle, firmly holds the cop-tube in position on the spindle until the yarn or thread has been exhausted or unwound therefrom.
The clamping-finger serves to prevent any longitudinal movement of the cop-tube upon the spindle after the spindle has been turned into the shuttle-body.
Figure l, in longitudinal section, represents a loom-shuttle provided with acop-tube holder embodying my invention. Fig. 2 shows a modified forni of my invention, and Fig. 3 is a section across the spindle and cop-tube near the end of the finger.
The shuttle-body a, of any usual shape, has a spindle b, of usual shape, it having' a shoulder, as 2, against which is abutted one end of the cop-tube c, of usual construction, or such as commonly employed on mule-spindles to receive the yarn being spun in the mule.
The spindle shown in Fig. l has as its fulcrum a pin d, and the spindle is retained upon the said fulcruin-pin by means ot the usual spring-actuated pin e and spiral spring e. The spindle in Fig. l has connected to it by a rivet 3 the cop-tube-holding finger f, it being composed of thin metal, preferably spring metal, the free end of which is preferably of concavo-convex shape, as shown at 4, to come against and fit snugly the eXterior portion of the cop-tube at or near the shoulder 2 when the spindle is turned into the shuttle-body, as shown in the drawings. IVhen the spindle is lifted or turned outwardly from the shuttle-body, the clampingfinger meet-s the pin 6, which arrests its movement and carries the end 4 away from the cop-tube, thus leaving the latter free to be moved longitudinally upon the spindle.
In Fig. 2 the cop-tube-holdin linger is somewhat diiferently shaped vfrom that shown in Fig. l, it being pivotally connected at8 to the head of the usual spindle, having its tulcrum on a pin 10, the head of the spindle being acted upon by a spring 12, of common construction, the operation of which is well understood. vWhen the shuttle-spindle shown in Fig. 2 is turned into the shuttle, as indicated, the finger f meets the shoulder I3, (shown as forming part of the shuttle-body,) and the shuttle-spindle, acted upon by the spring 12, is pushed upon in such direction, while the finger f rests against the shoulder I3, that the end of the finger acts againstand clamps the cop-tube.
By simply turning the spindle shown in with the shoulder 13 is released, thus releasing the pressure between the finger and the cop-tube.
I do not desire to limit my invention to the exact shape of the end of the finger to come in contact with the cop-tube; but I prefer to shape it so as to present a concavo-convex portion to extend somewhat around the coptube.
I claim- The combination, with a shuttle-spindle having a shoulder or stop to support one end of the cop-tube, of a cop-tube-holding finger to clamp the said cop-tube between itself and the shuttle-spindle, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
PLINY T. LITCHFIELD.
