I BOBBIN Fil-ed March 27, 1941 a m Joseph Capzma'ugk j j Patented Nov. 11, 1941 UNITED STATES PATENT OFFICE BoBBnv Joseph C'avanaugh, Barrington, N. Application March 27, 1941, Serial No. 385,543
4 Claims.
This invention relates to an improvement in bobbins, and more particularly to an improved construction of bobbin spindle by means of which the thread may be readily attached to the spindle to prevent the thread from slipping relatively to the bobbin spindle during the initial stages in the winding of the thread on the bobbin.
More particularly, it is an aim of the invention to provide a spindle having an annular outwardly opening groove having circumferentially spaced portions of different widths, adjacent the periphery of the spindle, to provide wide grooved portions for readily receiving the end of a thread and more restricted grooved portions in which the thread will be wedged and held as the bobbin rotates.
Still another aim of the invention is to provide a bobbin having means for catching and holding an end of a thread to be wound thereon and by means of which the end of a thread can be eifectively engaged in less than a single revolution of the bobbin.
Still a further aim of the invention is to provide means for catching and holding the end of a thread to be wound on a bobbin which is so arranged that rotation of the bobbin for winding the thread thereon will tend to direct the thread in a direction so that it will be more tightly wedged and held, whereas the rotation of the bobbin for unwinding the thread therefrom will be in a direction to cause the attached end of the thread to be readily released.
Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, which illustrates a preferred embodiment thereof, and wherein Figure 1 is a plan view of a bobbin constructed in accordance with the invention,
Figure 2 is a sectional view of the same, taken substantially along the plane of the line 2-2 of Figure 1,
Figure 3 is a fragmentary plan view of a portion of the bobbin spindle and on an enlarged scale, and
Figures 4 and 5 are sectional views taken. substantially along the planes of the lines 4--4 and 55, respectively, of Figure 3.
Referring more particularly to the drawing, wherein like reference characters designate like or corresponding parts throughout the diiferent views, Ill designates generally a bobbin including a spindle II which, as shown, is provided with a longitudinal bore I2 which extends therethrough.
The spindle II is provided with externally threaded ends I3. The bobbin I0 also includes a pair of heads I4 which are provided with centrally disposed threaded openings I5 for detachably engaging the threaded ends I3 for assembling the heads I4 on the ends of the spindle II. The parts of the bobbin III, previously described, are of conventional construction and areshown merely to illustrate the application of the improvements which will hereinafter be described, and said parts may therefore be varied Without effecting the improvements comprising the invention.
The improvement constituting the invention comprises an annular groove, designated generally I6 which is formed in the spindle II, intermediate of its ends, and which opens outwardly of the periphery thereof. The groove I6 is provided with spaced, substantially parallel side wall portions I'I, adjacent thebed I8 of the groove I6. The upper portions of the side walls of the groove I6 are flared outwardly to form the complementary portions I9 and the complementary portions 20. As best seen in Figures 1 and 3, the complementary portions I9 are circumferentially spaced by the complementary portions 20 which in turn are circumferentially spaced by the complementary portions I9. As best seen in Figure 3, the inclination or slant of the portions I9 is less than that of the portions 20 so that said portions I9 at their upper edges, and intermediate of their ends, are spaced a substantially greater distance apart than the corresponding edges of the portions 2!] to form circumferentially spaced portions ZI of the groove I6 which are substantially wider at the periphery of the spindle II than other portions of the groove I6. Furthermore, as best seen in Figures 4 and 5, the portions I9 extend to a greater depth in the groove I6 than do the portions 20. As seen in Figure 3, the portions I 9 taper from intermediate of their ends to the ends thereof where they merge with the portions 20.
From the foregoing it will be apparent that when the bobbin I0 is revolving and the end of a thread, not shown, is applied to the bobbin the end of the thread will readily enter one of the widened portions of the groove I6 formed by the portions I9 and will be wedged between the portions I'I, contiguous with the portions 20, as the bobbin I0 revolves. Furthermore, it will be apparent that the rotation of the bobbin II] will tend to pull the end of the thread toward the bed I8 of the groove I6 wherein it will be most effectively held. In unwinding the thread from the bobbin In it will be obvious that the direction of movement of the thread away from the bobbin will tend to release the end of the thread from the groove l6.
Obviously, the width of the various portions of the groove l6 as well as its depth will vary depending upon whether a thin or coarse thread is to be engaged therein. Various other modifications and changes are likewise contemplated and may obviously be resorted to as only a preferred embodiment of the invention has'been disclosed.
I claim as my invention:
1. A bobbin having a. spindle provided with an e annular groove, said groove having circumferentially spaced portions of different widths, ad-
of the. groove being approximately as great as the widest part thereof. i
2. A bobbin having a spindle provided with an I Y 15 jacent the periphery of the spindle and the depth;
annular groove, the side walls of said groove bethe periphery of the spindle, of difierent widths,
and the bed portion of the groove being of substantially the same width throughout.
JOSEPH CAVANAUGI-I.
