BOBBIN Filed Dec. 2, i950 INVENTOR Patented Jan. 19, 1932 UNITED STATES JOHN G. QUIGG, F PITTSBURGH, PENNSYLVANIA BOBIBIN,
Application filed December 2, 153%). Serial No. 499,475.
My invention relates to improvements in bobbins such as are used in the spinning of silk, and consists in such a modification of structure as permits economy in manufacture 5 and replacement of a portion subject to greater wear and consequent prolongation of the life of the major portion of the bobbin and economy in service.
In the accompanying drawings Fig. I is a 39 view in axial section of a bobbin of my invention; Fig. II is a view in end elevation of the same bobbin; Fig. III is a like view to Fig. I of a second bobbin, differing from the first-in detail but still embodying my invention; and Fig. IV is a fragmentary view in axial section of a bobbin, in association with which means are shown in eleva tion for effecting removal of the replaceable part alluded to.
The bobbin of my invention comprises a barrel 1 and opposite heads 2 and 3. The bobbin is hollow, to permit passage of a mounting spindle. It is desirable that the barrel be exteriorly of relatively great diameter and that the axial bore to afford bearing for the spindle be of relatively small diameter. Ad-
ditionally, for economy and lightness, it is desirable that the bobbin, when made of metal, be thin walled. Figs. I and III show in cross-section an outline in which these desired characteristics are present.
While it is possible to form integrally as a metal casting an article of such outline, the cost of production would be so great as to render such formation impractical.
My invention consists in forming the bobbin of such outline of a plurality of pieces. each of which may be formed as a die-casting and accordingly with economy, and in imposing upon the pieces such particular and minute features of shape that they may readily be assembled and separated and yet when assembled will be accurately assembled and be secure in their union; and informing as a separate and separable piece having such characteristics that portion of the whole which is subject tov wear in greater degree than the remainder. This piece then becomes a deciduous piece with respect to the remainder of the bobbin, and as such it may be removed and'replaced, and in consequence the life of the large portion of the bobbin may be very greatly prolonged. This, of course, is had with considerable economic gain and advantage. p
The right-hand head of the bobbin, as seen in Fig. I, is made relatively heavy, and in the end face a circular groove 31 is formed, with an obstructing web 32 across thegroove at one point. These structural features are characteristics with which my invention has nothing to do. I note them, and add that theright-hand end is the end engaged by the bobbin-revolving means, and thatit is the opposite end, the left-hand end, which'is free and unengaged except by the spindle which passes axially through the bobbin 1 The portion which consistsof'the barrel 1 andthe heads 2 and 3, as seen in Fig. I, is I open-ended to the left; at that end there is no diminution in the diameter of the bore of barrel 1. Accordingly,-that portion may ec'onon'iically be made as a die-casting. The head 2 becomes a flaring extensionat the end'of barrel 1, with walls of uniform thick- 7:; nessj with the walls'of barrel 1. i I form as a separate piece the bearing for the spindle at. the left-hand end of the bobbin. This piece'takes theform of a bushing 4 adapted to be secured in the bore of barrel 1. The piece 4 is essentiallycylindrical in form," of external diameter at one end to" fit snugly within the barrel 1, and of internal diameter at the other end such as to afford proper bearingfor the spindle upon which the bobbin turns. 1 This piece too may be shaped as a die-castingwln assembly the piece 4 telescopes'in theotherwise open left-hand end ofithe barrel 1 and being accurately proportioned it is secured by the snugness of fit. Exteriorly the piece 4 is provided with an outstanding ridge or collar 41. This ridge is shaped to abutupon and to fit snugly upon the, face of the body portion where the barrel 1 begins to flare, to form the head 2. By such abutment the piece 4 when forced from left to right into barrel 1 comes accurately to position, completing the bobbin with accuracy in proportions. Furthermore, the introduced piece 4 becomes reenforcement,
strengthening the bobbin, particularly at the base of the flare of the relatively thin-walled piece from barrel 1 to head 2.
The bobbin is mounted in the spinning apparatus by engagement at its right-hand end with other machine parts; the left-hand end remains unengaged. Accordingly, in prolonged use it is the bearing at the left-hand end, the bearing formed in piece 4 which reveals greater wear. IVhen unduly worn piece 4 may be removed and replaced with a new piece, and by such replacement the life of the body portion of the bobbin may be greatly prolonged. In Fig. IV I shoW pulling apparatus, consisting of a spider 5 equipped with a bolt 6, and with grapple hooks 7 carried by the bolt. By such an instrument the piece 4: may with facility be withdrawn from its place in barrel 1 when, worn in service, it is to be replaced.
Fig. III shows that similarly as the bearing at the left-hand end of the bobbin may be formed as a separate piece and seated by telescoping snugly in the barrel 1, so the bearing at the right-hand end may be formed as a separate piece, assembled in like manner in the right-hand end of barrel 1. The piece 8 also may be formed as a die-casting. It is replaceable either because of wear or to adapt the bobbin to assembly with machine parts of differing proportions.
I claim as my invention:
1. A bobbin including a cylindrical barrel provided at one end with an integrally formed flaring head, and a cylindrical bearing block provided externally with an outstanding collar, said bearing block adapted to enter the said barrel telescopically at one end thereof and to engage over its exterior surface the interior surface of thebarrel, with the said outstanding collar in abutment upon the flaring head at the base of the flare thereof, whereby the said bearing block, accurately positioned in the barrel, becomes reenforcement, strengthening the structure at the base of the flare.
2. A bobbin including a cylindrical barrel portion provided at its ends with integrally formed flaring heads and additionally at one end with an integrally formed spindle bearing, and a spindle bearing block with outstanding external collar adapted to be mounted telescopically in the-otherwise open end of the barrel with the said outstanding collar in position-defining and strength-giving abutment upon the barrel portion.
In testimony whereof I have hereunto set my hand.
JOHN.G. QUIGG.
