Application February 1, 1947, Serial No. 725,945
11 Claims.
This invention relates to a novel spool or bobbin construction.
Various built-up spool or bobbin constructions have been proposed in the prior art. The pres-- ent invention provides departures from the constructions of the prior art which afford numerous advantages in manufacture, particularly in mass production, and in the usefulness of the resultant product.
In pursuing the teachings of the present invention, it is possible to fabricate a, sturdy and rigid spool or bobbin from a minimum number of simple parts which lend themselves readily to economical production on a. large scale by molding from any of a wide variety of synthetic resins or plastics.
Further, the construction of the present invention is such that the major parts of the spool may be used interchangeably to form spools having various base diameters. Base diameters as here used means the diameter of the drum or element upon which the material for which the spool is provided is wound. The spool of the present invention comprises a pair of interfitting end members or heads which engage over the ends of a short sleeve element which comprises the surface upon which the material is to be wound. Sleeve elements of various diameters may be engaged between a given pair of end members to provide spools of various effective sizes.
A detailed embodiment of a spool or bobbin constructed according to the present invention is illustrated in the accompanying drawing and described in the following specification. However, the principles of the present invention are not limited to the form shown by way of example nor otherwise than as defined in the appended claims.
In the drawing:
Fig. 1 is a perspective view of a completed spool or bobbin;
Fig. 2 is a cross-sectional view taken on the line II-II of Fig. 1; and
Fig. 3 is an elevational view of the inner face of one of the end members of the spool or bobbin of Figs. 1 and 2.
In the several figures of the drawing, like characters of reference denote like parts. and the numerals Ill and II designate a pair of circular end members individually molded from synthetic resin or other suitable plastic material. The end members l and l I are provided with telescoping central sleeve-like projections I3 and I4, respectively. Either the external periphery o1 projec ment. The external tion l3 or the internal periphery of projection M or both may be very slightly tapered in the'molding step to facilitate assembly and insure a tight fit The facing radial surfaces of end members I 0 and H are each provided with a series of concentric circular ribs l6 and 11, respectively. The several ribs l6 and II are equally spaced in a radial direction to provide a series of seating grooves and in Fig. 2 a cylindrical sleeve element 20, likewise preferably of molded resin, is shown with its ends seated between pairs of adjacent ribs- [6 and IT. The dot and dash lines at A in Fig. 2 illustrate the fact that, in the alternative, another sleeve of considerably less diameter might be seated between another pair of the ribs [6 and IT, in place of sleeve 20, to provide a spool of greater capacity within the same end members l0 and H.
During assembly the circular grooves of the end members I0 and II which are to receive the ends of sleeve 20, or the ends of sleeve 20 themselves or both, are provided with a suitable ceperiphery of projection l3 and the internal periphery of projection M are likewise provided with cement, so that when the device is assembled as shown in Figs. 1 and 2, the parts I0, I and 20 bond into an integral unit which, while it basically may be made of relatively low strength synthetic resin, provides a very rigid, strong, and attractive spool or bobbin.
The material normally used is moderately resilient and the proportions may be such that when the projections l3 and M are pressed to finally assembled position the radial walls of end members l0 and l l are flexed slightly outwardly by the sleeve 20, so that they clamp sleeve 20 with resilient pressure.
