Description

Lhasa vi i- Tqalkwho'm it may concern:

Be it known that I, Gnome Human r Bm amwrnvfacitizen of the United States,

51 -in'to-the shuttle. r v "The object of my invention is to produce transverse section on the line 11-41 of Fig.

residin in the city, county, and State of New" ork,"-have invented certain new and euseful Improvements in Bobbins, of which the following is a specification.

invention relates to bobbins of the type whichf'are"speciallyedapted for use with leoms wherebobbins are automatically fed a bobbin in whichthe rings on the lower paitof the 'bobb1n, which coact with the inte'ri'orof'th'e shuttle, shall be so arranged as to retain their space relation and fun thenthat the tube on the interior of the base of the bobbin, which coacts wit the shank ,oi clutchof the spindle whirl, shall be so corresponding in height with the acting surfacesiof the clutch and maintain a fixed pbsition relative to the body of thebobbin, and"thus' be.prevented from turning within the bobbin'or dropping out of the bobbin,

owing to the shrinkage of the material of which-the bobbin is made, etc,

ffA- f1irther object of my invention is to provide a base for a bobbin which may read- -il'y" be secured to old shankswhich have split at? the base, and thus al low the rings to dro'pofi. r o v 'The accompanying drawings will serve illustratelmy' invention, in which Q Eigure 1 is a side elevation.

portion consists of a tubular member 16,

basemember 17, arm members 18, provided with horizontal grooves 19, and ring members 20, which may be of well known construction and secured in position in the usual manner. The tubular member 16 is adapted tor-fit within the cavity l5 of the head 11; the base member 17 to be located under the bottom of the head 11; the arm members 18 in the grooves 13, and'the ring members 20in thegrooves 12 of the head 11, and in the grooves 19- ofthe arm members 18v It will be observed that the grooves 19 of the arm members 18 are in alinement' with the grooves 12, and as the arm members 18 have the grooves 19 deli nitely .spaced, the ring members 20 will be held in a defined position as regards each other, and irrespectiveof shrinking or splittingolt' the head 11 (with the consequent displacement of the grooves 12), and further, that as the arm members 18 are situated in grooves 13-of the head 11, there can be no rotation of the tubular member 16 within the cavity 15 of the head 11, which rotation is apt to occur by the frictional resistance between the tubular member and the driven whirl, shank or clutch, when, a tubular mem. her is inserted into the base of a bobbin and ot secured therein, except by the pressure due to the resilient action of the material of which the bobbin is made.

21represents a spindle whirl, provided wit-ha shank E22 and clutch 23: It will be observed thatthe clutch 23 coacts with the interior of the tubular member 16. Manifestl'y the shape of the tubular member may be any thatisrequired to dooperate with any special design of. clutch, or as is usual, it may bexcone-shaped so as to cooperate with the ,ordinary cone-shaped spindle shank.

tubular member 16 is pressed into the wood at 27. Any other means of securing the 1 base member to the head 11 may be adopted.

In all of the figures, I have shown the interior tubular member and the exterior memhere as formed of a single pieceof metal.

Manifestly, for convenience of manufacture or otherwise, the tubular member, the base "member, the arm members or theexterior shell m mber, can allbe formed of separate pieces or material secured by. rivets or otherwise .without in any'wis'e 'de arting from the intent of my invention.
