CONICAL BOBBIN ARRANGED WITH STEPS Filed July 5 1927 Patented May 21, 1929.
UNITED STATES PATENT OFFICE.
MAX WIELAND, or AUERBACH, NEAR onniumrz, GERMANY.
CONICAL BOBBIN ARRANGED WITH STEPS.
Application filed July 5, 1927, Serial No. 203,659, and in Germany July 8, 19136.
This invention relates to bobbins upon which is wound thread or yarn, etc., used in the textile industry, and has for its object to provide a conical or bottle shaped bobbin having formed thereon a plurality of sets of annular steps, each set of steps differing in depth and height from the adjacent set, the arrangement of which steps allows the thread .to be wound on the bobbin more evenly, prevents the thread from forming beads or beat formations, and avoids the unintentional slipping off of the thread wound on from the bobbin. 7
Another object of the invention is to provide a conical bobbin having a plurality of sets of annular steps,each set of steps differing in depth and height and disposed with a set of steps having the least depth and height at the largest end of the conical bobbin.
A practical embodiment of my invention is represented in the accompanying drawings, in whichi Fig. 1 represents an elevation of a conical bottle shaped bobbin having my improvement applied thereto;
Fig. 2 represents a similar view of a modified form of bobbin showing the thread and thread guide diagrammatically;
Fig. 3 represents a similar View of the bobbin with the. thread and thread guide removed; I
Fig. 4 represents another modified form of bobbin, and
Fig. 5 represents an elevation of a eonical bobbin.
In Fig. 1 the cylindrical bobbin is denoted by a, and t e conical portion by a, a A thread guide 6 (shown in Fig. 2) is located in its extreme position at one end of the bobbin and is moved to uide the thread 0 as it is wound on the bobbin.
The conical portion a of the bobbin is provided with a set of annular steps 6, each of said steps having substantially the same depth and equally spaced apart. Each of the steps has a different diameter from that of the adjacent step, The conical portion 0.
of each step is smaller than the diameter of the adjacent step as it approaches the cylin- 'd'ricalportion (k Th t of steps e are portion of the smaller in depth and height butlarger in diameter than the set of steps 6. From the foregoing it will be seen that the conical portion of the bobbin has two sets of steps, each set of steps diflfering in depth and height, and disposed with the set of steps having the smallest depth and geight at the largest end of the conical boblIl.
In the form shown in Fig. 4, the conical bobbin is provided with a set of steps e,
a set of steps e havin a smaller depth and \height than the set of steps a, and a set of steps e, which set of steps is smaller in depth and height than the set of steps e In this form, the sets of steps progressively increase. in depth and height as they decrease in diameter.
In the form shown in Fig. 5 the set of steps 6 is developed to the extreme small end of the bobbin, while a set of steps 6 is arranged to progressively increase in diameter and diminish in depth and height toward the large end of the bobbin. 4 j
While I have shown and described the set of steps having the smallest depthand height dis osed at the largest end of the conical bobbin, I also find it advantageous to locate a set of steps 'havin asmaller depth and height at each end 0 the conical b0 bin and a set or sets of steps having a larger depth and height interposed between the set of steps of smaller depth and hei ht;
It has been found in practice that 8. bob in formed with sets of steps having a different depth and height wound with thread will hold the body of thread firm and even. Furthermore:i by this structure the thread will.
be woun on the bobbin uniformly,.without being caused to pile u and form beads on the end of the bobbin where the thread guide changes its direction.
What I claim is:
1. A bobbin com rising, a conical ortion.
provided with a p urality of sets 0 annular steps, each set. of steps being decreased in depth and increased in diameter.
2. A bobbin comprising a conical portion provided with a lurality of sets of annular steps each set oi steps being decreased in depth and height and increased in diameter.
3. A bobbin com rising, a conical ortion provided with a p urality of sets 0 steps, each set of steps having a different depth from the ad'acent set of steps, the smallest depth of said sets of steps being disposed at the larger end of the conical portion.
4. A bobbin comprising; a conical portion I 5 provided with a plurality of sets of steps,
each set of steps having a different depth and hei ht from the adjacent set of steps, the sma ler depth and hei ht of said sets of steps being dlsposed at t e larger end of 10 the conical portion.
5. A conical bobbin provided with a plurality of annular steps of difier'ent depths In testimony that I claim the foregoing asmy invention, I have signed my name this 21st day of June, 1922.
