WEAVERS SHUTTLE.
SPECIFICATION forming part of Letters Patent No. 761,099, dated May 31, 1904.
Application filed June 17, 1903. Serial No. 161,953. (No model.)
To all whom it may concern:
I enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to improve ments of the means of supporting the bobbin or cop with the filling in weavers shuttles.
The spindles as they are used at present in the shuttles allow the bobbins to slide consid- .erably when the shuttle arrives at the end of the race, thereby causing the weft to unwind to an extent and make it liable to entanglement and to breakage.
The object of the present invention is to avoid this inconvenience, and to this end the spindle is provided with means which allow the cop to slide under the influence of the impact and to return immediately into its original position.
In the accompanying drawings, illustrating my invention, Figures 1 and 2 show in elevation the spindle with spindle-head adapted to turn .on the ordinary pivot in the shuttle and showing the parts in the two positions they can take while at work. Fig. 3 is a crosssec' tion on line 4 1 of Fig. 1. section on line 5 5, Fig. 2.
The spindle constructed according to the present invention comprises a tapered shaft 11, having ahead 12 of U-shaped cross-section. The flanges of this head 12 are connected by a cylindrical body 13, having a central aperture 14, adapted to fit over the pivot or pin of the shuttle around which the spindle is turned in the ordinary manner whenever it is necessary to exchange the spool. A coil -spring 15 is wound around the body13, one end being attached to the web connecting the flanges of the head, said web being preferably cut away in part to give room to the body 13 and the windings of the spring, the other end of said spring beingconnected to a link 16, which turns on a hinge of a collar forming part of a sleeve 17, adapted to slide longitudinally on the shaft 11.
Fig. 4 is a crossing inactive.
Said sleeve is longitudinally slotted and bent, as shown, presenting frictional springs in the same manner as the cores used in connection with spindles of spinning-machines. Itis obvious that the cop carried by the sleeve 17 will undergo a limited longitudinal displacement jointly with the sleeve, thereby tensioning the spring 15, which will return the sleeve and the cop immediately into original position.
It is evident that the spindle as described can be used in ordinary shuttles in place of the old spindle by simply placing the body 13 upon the pivot, no change being necessary for the shuttle.
An important feature of my improved spindle is that it is lighter than the spindles usually used. Hence by using it the wear and tear of the weft is not increased. The displacement of the sleeve 17 caused by the shuttle striking against the shuttle-box or by the workman taking the cop off is controlled by the end of the spring 15, attached to the link 16, being capable of only a limited motion, which, beside the resilience of the spring 15, is dependent on the circumstances that on the spring 15 being contracted its coils approach the body 13 till they are snugly and quite close upon it when the extreme limit of the action of the spring is reached. It is easy to calculate the diameter of the body 13, Fig. 3, so that the maximum possible contraction of the spring 15 will not exceed the limit of the elasticity of the spring, (for a desired number of contractions within a unit of time,) and consequently to provide a spring which will work without any deformation-that is, which will preserve its elasticity through an indefinitely long period of time. It may be observed here that the flange or collar of the sleeve 17 is made of a diameter sufliciently large to permit the workman, whose duty it is to remove the cop from the sleeve 17 (which manipulation, it is known, is repeated some thousand times a day) to grip the collar with the fingers and to remove the cop, the spring 15 remain- This. is, however, a secondary consideration, since the extent of the contraction of the spring being limited this removal may be effected an indefinite number of times without injury to the spring whenever the sleeve is not retained by the hand. From the permanency of the elasticity of the spring 15 it follows that the sleeve 17 when displaced from the normal position will return into it each time with the same force, the extreme inner end of the sleeve 17 being violently thrown against the head 12. Owing to this the cop carried by the sleeve 17 is forced back to its initial position whenever it has been displaced.
Havingthus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
A spindle for the bobbins of shuttles composed of a shaft with a U-shaped head carrying a sleeve adapted to slide longitudinally upon the shaft and to support the bobbin, said U-shaped head having between its flanges a v
