Description
June 27, 1939. A. D. MULLER BOBBIN Filed Oct. 20, 1937 Inventor Aiiorneys Patented June 27, 1939 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to bobbins, the term of. bobbin as herein used being intended to comprehend bobbins of various types and analogous devices on which silks, rayons, cotton or woolen yarns and the like may be wound and from which the same may be delivered at the knitting machines or looms.
The object of the invention is the provision of a bobbin capable of being manufactured with facility and so characterized as to assure perfect winding of silks, rayons, cotton or woolen yarns and the like and the free delivery of the thread.
To the attainment of the foregoing the invention consists in a bobbin of cast metal, compressed or molded fibre, or other material compatible with the purpose of the bobbin, characterized by knurled sections or panels separated by intervening spaces; the knurled sections or panels in conjunction with the smooth or plain surfaces intermediate of the knurled sections or panels contributing to perfect winding of silk and other thread and also contributing to the free delivery of the thread from the bobbin, all as hereinafter described and definitely claimed.
The present application is a continuation in part of, my application filed on March 1, 1935, Serial No. 8,933.
The invention together with its objects and advantages will be best understood from a study or" the following description taken in connection with the accompanying drawing wherein:
Figure 1 is an elevation of a shipping and conditioning cone type of bobbin constructed in accordance with my invention.
Figure 2 is an elevation of a bobbin of winding conditioning and shipping cone type embodying my invention.
Figure 3 is an elevation of a bottle bobbin constructed in accordance with my invention.
Figure 4 is a transverse sectional view taken substantially on the line 44 of Figure 1.
Figure 5 is a fragmentary detail sectional view taken substantially on the line 5-5 of Figure 2 and Figure 6 is an. enlarged fragmentary detail horizontal sectional view showing clearly cer tain details of the invention hereinafter more fully referred to.
Within the purview of my invention the bobbins may be, and preferably are hollow; and may be, and preferably are formed by the wellknown die-casting process, the shells of the bobbins being milled out in a manner to provide roughened panels or surfaces, with plain or smooth surface portions or panels arranged intermediate of the roughened surface portions or panels; the roughened surface portions or panels being characterized by having the nodes thereof pyramidal, rounded at their apices, and providing intersecting lines or grooves for receiving therein the thread or yarn, with the lines or rooves so formed being interrupted at intervals by the smooth surface portions or panels which latter act as guides for the thread as will be hereinafter made manifest.
In Figure 1 the winding, conditioning and shipping cone type of bobbin l is illustrated, and. in accordance with the present invention is pro vided with longitudinal knurled sections or panels 2, separated by plain or smooth surface portions or panels 3 extending longitudinally of the bobbin on the exterior thereof.
In the cone type of bobbin I ashown in Figure 2 the roughened or knurled sections 2a, and the plain or smooth surface sections or panels 3a extend circumferentially, with the knurled sections or panels 2a separated by the intervening plain or smooth surface sections or panels 3a; it being noted that the plain or smooth circumferential sections or panels 3a are provided also below the lowermost knurled section or panel 2a and above the uppermost section or panel 2a.
In the bottle type of bobbin, shown in Figure 3, the knurled sections or panels 21) are extended longitudinally of the bobbin on the exterior surface thereof and are separated by longitudinally extending plain or smooth portions or panels 31). The arrangement of the knurled or roughened sections or panels 212 and the smooth sections or panels 31) is substantially the same as that disclosed in Figure 1.
As will be clear from a study of Figures 4 to 6 inclusive, the surfaces of the smooth sections or panels protrude radially slightly outwardly beyond the apices of the nodes forming the roughened or knurled sections or panels, and the surfaces of the smooth panels are highly polished so that these smooth surface sections or panels serve effectively as tracks or glides for assisting delivery of the thread especially as the primary winding of the thread on the bobbin is reached and is being delivered from the bobbin. As has been found in actual practice, by having the roughened surface portions or panels and the smooth surface portions or panels alternately arranged and with their exterior surfaces substantially coplanar or, at best, with the exterior surfaces of the smooth panels projecting slightly beyond the plane of the apices of the nodes which constitute the rough surface sections or panels a full delivery of every inch of material wound on the bobbin is assured.
In addition to this assurance of full delivery of thread from the bobbin, a further advantage is that the apices of the nodes being rounded, instead of coming to very definite points at their apices, the likelihood of the thread breaking or throwing the bobbin off its base, causing a stoppage of the machine with consequent waste or necessitating back-winding onto another bobbin, is effectively guarded against.
The above will be appreciated when it will be considered that Were the apices of the nodes pointed, the points of the nodes would have a tendency to pierce the threads, breaking the fibres or strands thereof, or else weakening them to such an extent that the least undue strain, as might result by the.thread becoming hooked onto the pointed ends of the nodes, could only result in the breaking of the thread. Hence the rounding of the nodes at their apices is a very salient feature of the present invention.
Also, by having the nodules forming each roughened or knurled surface section or panel arranged as to provide intersecting diagonal lines or grooves for receiving therein the thread wound on the bobbin, a cross-winding of the thread on the bobbin may be had, the windings of the thread lying within the lines or grooves formed by the nodules.
It will be apparent from the foregoing that my novel bobbin, characterized by knurled panels or sections separated by plain or smooth surface panels or sections is susceptible of being readily and inexpensively manufactured; and that by reason of the plain or smooth surface sections or panels in conjunction with the knurled sections or panels adjacent the plain or smooth surface sections or panels the bobbin is enabled to better prevent slipping of the thread and is calculated to assure perfect winding of the thread and the free delivery of the thread from the bobbin at the knitting machine or loom.
In connection with the above it might also be stated that cone bobbins of the type for which my invention is primarily intended are not supported on the machine by any extraneous sup ports but are merely sustained in proper position by their own Weight. Consequently, it is expedient that a free yet controlled delivery of the thread be assured, and to that end the plain or smooth surface sections or panels are slightly radially projected beyond the nodes of the roughened surface sections or panels and are highly polished; with of course the nodes or nodules at their apices being rounded off instead of pointed so as to preclude against any hooking of the threads on these nodes or nodules. Hence, with my invention the thread may be fed from the bobbin Without any substantial danger of the bobbin being tilted, which latter is objectionable since it causes stoppage of the machine and oftentimes much undesirable waste of time and material.
It is thought that a clear understanding of the construction, utility and advantages of. an invention of this character will be had without a more detailed description.
Having thus described the invention what is claimed as new is:
A bobbin having on its exterior surface a plurality of alternate rough and smooth surface panels, the smooth panels being highly polished and of substantially the same width as the rough panels, the rough panels being formed of a plurality of minute nodes located in rows and having their apices rounded and said apices terminating inwardly of the surfaces of said smooth surface panels.
