To all whom t may concern;

Be it 'known fthat I, THOMAS PETER ROONEY, a citizen of the United States, :re-l siding at New Bedford, in the county .of 'Bristol and State of Massachusetts, have 1nvented new and useful lmprovements in BobbineHolderspof which the following is a. specification.

This invention relates to improvements in bobbin holders forcreel frames, the primary object of the invention being to provide .a bobbin holder which admits of the easy motion and the ready application and removal of the bobbin, so that ybobbins -o-f different lengths may be employed with ease and facility.

A further object of the invention kis to provide a bobbin holder which is simple of construction, inexpensive of production, eliminates the use and handling of skewers and the objections incident thereto, and which is vdust-proof, avoids the `use of oil as a lubricant and saves wear and :tear upon the bobbin, creel frame and the roving.

A still further object of the invention is to provide a bobbin 'holder which l.will handle line and coarse 4rovings with equal facility, Awhich obvia-tes the expense of re plenishing parts at frequent intervals, as 1n the use yof lwooden skewers, Yand which .reduces labor and mainte-nance `of .cost to a material degree.

The invention consists of the features of construction, combination and arrangement of parts hereinafter full-y ydescribed and claimed, reference being had :to the accom.- panying drawing in which Figure 1 isa sectional elevation showing the application of the invention.

Fig. 2 is a detail section on line 2-2 of Fig. 1.

`Fig. 3 is a detail section on line 3-3 of Fi l.

eferring to the drawing, 1 and 2 respectively designate the upper and lower creel boards or rails of a creel frame, and 3 the bobbin having the usual longitudinal passage 4 terminating at its lower end in the opening 5, of greater diameter.

The bobbin is rotatably supported from and between the creel rails 1 and 2 by upper and lower holders 6 and 7. The upper holder 6 comprises a head 8 preferably made of porcelain, and which is of semi-oval or elliptical form, having the tapering lower end 9 which tits within the opening 4 at the upper `end of the bobbin and an internal chamber or socket 10. Into this chamber fits rthe lower end or circular -portion 111 of a fastening bolt, 12, the upper Lend or portion 13 of which .is threaded and passes through the creel bar 1 and `is equipped at its `upper end with a clamping nut 1&1 and washer 15. The bolt portion 11 forms a spindle on which the head 8 is fitted -to slide and revolve, and said portion of the bolt extends into the chamber 10 and through a fiber .bushing 15 `fitted in said chamber and secured therein by screws 16, the lower end of the bolt being provided with a flange 17, whereby the head Vis held against downward displacement and its downward motion limited. At the point of junction .of its spindle and threaded stem portions the bolt is formed with a shoulder 18, and this shoulder is arranged to bear against a base plate or disk 19 Vwhich engages the underside of the rail 1 and is clamped `by said shoulder in position. rllhis base plate,- which may be made of fiber or other suitable material, carries a tubular shield or Ycasing 20 which extends downto embrace the head 8 and serves as a guard to prevent the entrance of dust and dirt. This 7tube also serves lin conjunction with the spindle as a guide for the head 8, `which is kfit-ted to slide upward on said spindle so that itmay :be withdrawn from engagement with ythe opening 4 in the bobbin, kthus permitting different bobbins to 4be applied rand removed with facility and bobbins of different lengths to be used.

The lower bobbin support 7 `comprises a head 21 of hemispherical form, having lits convex face upwardly disposed and fitted within the opening 5 of the bobbin, whereby the bobbin is supported and held in position upon the creel rail 2. The head 21, which, like the head S and base plate 19, is also made of porcelain or other suitable material, is formed with a socket 22 and an annular chamber or cavity. Extending into said socket 22 is the upper circular portion 23 of a fastening and pivot bolt 211, having a threaded stem or shank 25 which passes downward through a threaded opening in a. base plate 26 and also through an opening in the lower creel rail 2 and is equipped at its lower end with a nut 27 and washer 28, whereby said bolt and the base plate are fastened in position upon said rail. As shown, the base plate is preferably provided with a thickened or depressed central portion having a threaded opening to receive and engage the bolt, which is provided-at the junction of its circular and threaded portions with a shoulder 20 to engage and clamp said base plate in place. Preferably the base plate is formed with an upstanding dust guard or flange 30 which extends into the chamber or cavity of theJ rotary head 21 and prevents the entrance of dust or dirt, and the outer edge of the base plate is also preferably beveled oil', as shown at 31, to shed and prevent the accumulation therearound of any dust, dirt, lint or other foreign substances. Fitted within the socket of the head 21 is a fiber bushing 3Q which turns with the head upon the spindle of the bolt, which spindle is provided'with a iiange 33 to prevent upward displacement of the head and also with a conical point or projection 34 acting as a bearing engaging the crown of the head and on which said head is centered and mounted to rotate. By this construction it will -be seen that the lower end of the bobbin will be engaged and held from displacement by the conveX surface of the head 21 which will revolve freely on its aXis, thus coperating with the upper head to permit the bobbin to have easy motion without the necessity of employing oil or other lubricant, the construction being such ,as to obviate the use of skewers and other similar devices and the objections incident thereto. Inasmuch as the heads are made of porcelain or other suitable hard and durable ma.- terial, it will be evident that the holder will last in active service for a very long period, and as these surfaces are mounted the catching and accumulation of lint and other foreign substances will be prevented and the smooth and even running of the roving Without binding, permitted. Furthermore, by simply sliding the head 8 vertically alone or with the bobbin, it will be evident that the bobbin may be unseated from the lower head and removed, and that the construction is such as to facilitate the operation of applythe combination with an upper supporting head, of a lower supporting head comprising a base plate, a spindle, a yhead fitted te revolve upon the spindle and having a cavity therein, and a dust guard flange upon the base plate and projecting upwardly into said cavity.

2. In a bobbin support,.an upper supporting head having a tapering curvedsurface, a lower bobbin vsupporting member having a hemi-spherical surface, means for mounting the member and permitting the rotation thereof, and a base plate having a flange at the edge thereof cooperating with the edge portion of the heini-spherical member and preventing the entrance of dust to the mounting means therefor, the base plate and head being spaced apart to form an annularcavity between said elements. v

3. In a bobbin support, an upper supporting head having atapering curved surface, a lower bobbin supporting member having a hemi-spherical surface and carrying a central boss below said surface and having an annular recess surrounding the boss, a pin projecting upwardly through said boss and providing al support upon which said lower bobbin supporting member may rotate, and a base plate having a ange at the edge thereof cooperating with the edge portions of the heini-spherical member and preventing the entrance of dust.

In testimony whereof I aiHX my signature.
