June 15, 1954 w. MILLER TWO-PIECE BOBBIN Filed July 25. 1951 -c HE INVENTOR. WILLIAM H. Mmen Patented June 15, 1954 UNITED STATES TENT OFFICE TWO-PIECE BOBBIN Vania Application July 25,. 1951, Serial No. 238,464
1 Claim. 1
The present invention relates to certain new and useful improvements in bobbins or spools of the type used in the textile industry, but inasmuch as the bobbin is suitable for other uses it is not to be limited to the particular and specific use above stated.
The primary object of the invention is the provision of a bobbin composed of only two parts and which provides a bobbin which is extremely simple and cheap of construction and which can be quickly, conveniently, and cheaply assembled.
Another object of the invention is the provision of a bobbin, or, spool in which the two parts composing the same are connected to one another, in assembly, in a novel and improved manner.
A still further objectv of the invention is the provision of a bobbin or spool constructed in a manner to reduce to the minimum the points where yarn might trap when being wound upon the bobbin.
Other objects and advantages of the improved bobbin or spool will appear in and be understood from the following description when read in the light of the accompanying drawings which illustrate the specific embodiments of the inventive concept.
In the drawings:
Figure 1 is a longitudinal sectional view through a bobbin or spool embodying the present invention, the spindle being shown in full n lines.
Figure 2 is a fragmentary vertical sectional View illustrating a modified form of the invention.
Figure 3 is a fragmentary vertical sectional view illustrating a still further modification of the invention.
The ordinary or conventional type bobbin 0r spool is composed of a multiplicity of parts and ordinarily it embodies separate heads which are suitably secured to the opposite ends of the bobbin barrel, whereas the present improved bobbin is composed of only two parts, one of which is a combined barrel and head and the other a combined head and core.
The parts composing the bobbin are made of a suitable plastic; such as Bakelite, and are moulded into the necessary and proper shapes or configurations. bin parts are machined or otherwise suitably finished to provide a close fit, as will hereinafter appear.
Describing the bobbin in detail and having reference to the construction illustrated in Fig. 1, there is a hollow barrel A having one end closed Certain portions of the bob- 2v by an integrally formed head B having a thickened central portion l. The opposite end 2 of the barrel is open.
The open end of the barrel is closed by a head. C having formed as an integral part thereof a core 3 which is joined to the head by a thickened disc-like central portion 4. This core is provided with a longitudinally extending tapered bore 5 for the reception of the elongated tapered por-- tion 5 of a spindle D.
The barrel adjacent its open end is provided interio-rly with a circumie-rentially extending groove 1 and the disc-like portion 4 of the core is provided with a circumferentially extending flange or collar 8 which extends into the barrel groove and retains the head 0 on the barrel. In the assembly of the bobbin a suitable compression type gasket 9 is positioned between the barrel endZ and the adjacent inner face or the head C.
The thickened central portion l of the barrel head B is provided centrally with a bore or passageway I!) which receives and supports the reduced end I! of the core. The bore Ill and the core end portion H are machined or otherwise suitably finished to provide a close fit. The spindle .portion 6 extends completely through the bobbin to extend outwardly beyond the bobbin head 13 as at E2. The end l2 of the spindle passes loosely through the ferrule-like element l3 car ried in the outer face of the head B.
In the assembly of the bobbin it is necessary to heat-expand the end of the barrel to permit the flange or collar 8 to enter the groove 7. It will be understood that when the parts cool the flange or collar will constitute a lock holding the head C firmly to the barrel end.
In conventional bobbins having separate heads at each end of the barrel there are two points where yarn might be trapped between the heads and the ends of the barrel, whereas in the present arrangement ther is only one point where trappage could occur. This advantage is also present in the modified forms of the invention hereinafter to be described.
The described construction, and also the hereinafter to be described constructions, provide a bobbin or spool which is extremely simple of construction and assembly and which obviates the numerous head fastening means found in corn ventional bobbins or spools.
Inasmuch as the modified forms of the invention are directed entirely to the means for securing the head 0 to the open barrel end 2, the figures of the drawings illustrating the modified forms of the invention are limited to a showing 3 of the barrel end 2 and the barrel head C and in the description of the constructions appearing in Figs. 2 and 3 the same reference characters and numerals are utilized where the parts are the same as have been previously described.
In Figure 2 the barrel end 2 interiorly is threaded and the head or core disc-like portion 4 is threaded to provide a rotatably insertable and removable connection l4 between the portion 4 and the barrel. The same compression type gasket 9 is utilized in this construction. The particular arrangement here illustrated provides a bobbin in which the two parts comprising the bobbin can be quickly connected to or disconnected from one another.
The construction illustrated in Fig. 3 is one in which it is not intended that the two parts comprising the bobbin be disconnected from one another after they are once assembled. In this particular arrangement th barrel end 2 is provided with the same circumferential groove 7 and the disc-like portion 4 of the barrel head is provided with a complementary circumferential groove 15 in which is mounted a split metallic spring ring Hi. In assembly, the ring it is contracted so that it will enter the open end of the barrel and when the ring is opposite the barrel groove '7 it will expand thereinto and lock the head C to the barrel end 2 in the manner clearly illustrated in this figure of the drawings. The same compression type gasket 9 is utilized in this construction.
Departures from the specific constructions illustrated can be made without departing from the basic inventive concept, and the invention is accordingly to be limited only by the terms of the hereinafter following claim.
What I claim is:
An improved two-piece bobbin or spool comprising, a one-piece hollow tubular barrel formed with a head at one end and having an open nonheaded opposite end, said barrel head being provided with a bore, a one-piece core formed with a head at one of its ends and having an opposite non-headed end, the core being of much lesser diameter than the barrel and extending loosely through the barrel, the headless end of the core being disposed in and snugly fitting the bore of the barrel carried head, the core head being in abutment with the open end of the barrel, the core immediately behind its head having a disclike portion extending beyond the surface of the core and snugly fitting within the open end of the barrel, the bobbin heads and core being provided with a passageway for the reception of a spindle, the barrel inward of its open end being interiorly provided with a circumferential groove, the circumferential edge of the disc-like portion of the core being provided with a circumferentially extending groove, a resilient expansible and contractable ring carried by the core groove and providing on the disc-like portion of the core a circumferential flange, and said ring expanding into and interlocking with the barrel groove for securing the two unitary bobbin parts together.
