lThis invention has For its object a Simple, durable and ellcient .construction of silk tluowsterspindlej which will ellectually hold the bobhin thereon and at the saine time prevent it from turning relatively' to the spindle the latter rotated, and the invention eonsiste in certain constructions and arrangements of the parts that l shall hereinaitei fully describe and claim.

For a full underetamling` oi' the invention and the merite thereof and also to acquire a knowledge el the details et construction ef the means@ lor effecting; the resultreference is to he had to the following description and accompanying drawings;7 in which.

Figure l is a longitudinal sectional view of myliinpreved spindle vwith. the hohhin thereon.- En 2 is a detail perepec-tive view of the spindle detached.

' My improved silk throwstei' spindle is provided with the 'usual journal ends and is also provided at one end witl'i the usual cylindrical head 2. A tapered hushingg 3 surrounds one end of the spindle l and iilewitli" in the inner side of the head 2, said bushing tapering towards the opposite end of the spindle, as; clearly illustrated in the drawings. .Preferably this bushing secured to the spindle hy the saine pin 4 which secures the head 2 thereon.

so, through. the longitudinal Slot 12in the spindle. The proportions of the parte are euch that Whei'i the hohhin is slipped over the spindle with the tapered bushing 3 fitting snug y in the tapered. end el the bore of the hohhin, the shoulder il will enea e with the opposite end of the here in the he ihin, While the oulged or rounded head 11a will 'pro trude from that end of the hohhin and hear against the Said endso as to hold. the holahin snugly on the spindle; the springlatch har 7 being held under tension and the head lla effectuallv prevent-ing the hohhin from Working longitudinally oils the spindle. li hears outwar illy against the hobhin at one and of the here, and the tapered bushing edges into the tapered portion of the bore. Hence, any rotary ineveinent of the hohbin independently of the spindle is effectively prevented.
