July 27, 1965 w. A. WARNOCK HOLDER Filed Oct. 5, 1962 INVENTOR. WILLIAM A. WARNOCK his A TTORNEYS.
United States Patent 0 3,197,156 HOLDER William A. Warnoclr, Spartanhurg, S.C., assignor to Whitin Machine Works, Whitinsville, Mass, a corporation of Massachusetts Filed Get. 5, 1962, Ser. No. 223,663 9 (Ziaims. (Cl. 242-1302) This invention relates in general to holders and more particularly to rotatable bobbin holders for spinning machines.
Most types of bobbin holders, heretofore used for suspending bobbins in the creel of a spinning frame, have many parts including spring-actuated fingers made to engage the usual shoulder at the upper end of the bobbins. One of the main objects of the present invention is, therefore, to provide a bobbin holder of the type described which is economical to manufacture and which requires a minimum number or" parts. The present invention provides a simple design which is not only economical to manufacture but is also eficient in operation.
The invention includes a rotatable holder comprising :an overhead support to which a body portion is rotatably mounted. The body portion is generally elongated and has a channel passing transversely through its center. The lower portion of a movable slide positioned within this channel protrudes when the slide is positioned at its lowest point in the channel. This protruding portion supports at least in part the weight of a rotatable bobbin which can be mounted about the suspended body portion. This design includes limiting means for fixing the lowest position for the movable slide and provides a method for retracting the protruding portion of the movable slide when the rotatable bobbin or other object is being engaged or disengaged.
In addition many other uses are envisioned for this suspended rotatable holder in fields other than in the textile industry. Other objects and a fuller understanding of this invent-ion may be had by referring to the following description and claims taken in conjunction with the accompanying drawings in which:
FIGURE 1 is a slightly enlarged side elevation of the new bobbin holder;
FIGURE 2 is a vertical cross-section of the holder shown in FIGURE-l FIGURE 3 is a sectional plan view taken along line 33 in FIG. 1; and
FIGURE 4 is an elevational View of the movable bobbin holding member or slide.
Referring to the drawing, the bobbin holder comprises by spinning or crimping the upper end 17 of the body 7 over the outer race.
A dust cover '20 is mounted on the stud 14 against a shoulder 241 (and the cover is provided with a pin 22 upon which pivots a brake member 23. The upper end 16 of the stud -14-is threaded to receive a nut 24 which nu-t secures the dust cover and the stud to a slotted creel bar 25. When these parts are so assembled, the body id is free to rotate about the stud 14.
The bottom of the stud 14 has a tongue 26 and the bottom of the recess in the body 10 is provided with a groove 27. By raising the body so that the tongue enters the groove, the body can be used as a wrench to screw the stud into or unscrew it from the nut 24. In this manner the edges of creel bar 25 and cover 20 may be clamped tightly between shoulder 21 and nut 24, thereby rigidly fixing stud 14 in position. The anti-friction mounting, dust cover, brake and creel member are of conventional type.
The body 21b is molded from a plastic material, such as polyethylene, and its lower portion 13 is preferably of the shape shown in FIGURE 3, having its radial extremities defining a circle slightly less than the upper bore of a bobbin 29 on which is wound a roving package (not shown). As shown in FIGURES 1 and 2, the axis of the lower portion 13 is offset, preferably about three degrees (3), with respect to the vertical axis of the upper portion 11.
The body 10 is provided with an inclined slideway '30 as shown in FIGS. 2 and 3, in which is located a freely movable slide J1. Normally, this slide falls by its own weight until the surface 32 engages the edge 33 of the slideway 30. This is the lowest position which slide 31 occupies and its lower end '34 projects outwardly from the body it), as shown in FIG. 1.
When attaching a bobbin to the holder, segment 39 of the top inner edge 35 of the bobbin will initially engage the surface 35 of the slide so that the latter is moved upward to retract its lower end into the slot or slideway 30. The bobbin is then made to drop slowly allowing the slide to return to its lowest position, whereupon the lower edge segment 37 of the bobbin 29 will be engaged by the surface 33 of the slide, as shown in FIG. 1. In addition to this bobbin-slide engagement, the lower body portion engages bobbin 2 only at segment 39 of upper edge 35 and at lower edge segment 4%) of the upper bore 41. This is due to the approximate three degree (3) inclination or offset of this lower portion of the body. The bobbin :29, however, is consequently suspended with its .axis substantially parallel to the axis of the upper body port-ion 11, as shown in FIG. 1.
To remove the bobbin from the holder, the operator raises the bobbin to lift the slide 31 into position, as shown in FIG. 2. Here the bobbin 29 moves further valong the opposite side of the top inner edge 35 than during engagement, subsequently engaging the surface 32 of slide 31 and continuing to displace the slide upwardly until stopped by flange 12,. The operator then lowers the bobbin quickly, thereby preventing the surface 38 of the slide 3 1 from getting under the lower edge segment 37.
This invention thus provides a rotatable bobbin holder composed basically of two parts suspended from a ballbearing support. This simple and functional design thus provides the industry with a durable, inexpensive, easily replaceable bobbin holder which operates efiiciently as a spinning bobbin support and which may be easily engaged or disengaged from a creel frame in virtually a matter of seconds.
Although the invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereafter claimed.
For example, other embodiments are envisioned wherein the bracing or stopping surface which determines the lowest limit for the slide 31 may be located either within the inclined channel 39 or adjacent the lower opening of inclined channel and is, therefore, not strictly a function of surface 32. It is to be understood that other detail changes in design, such as replacing the upper cylindrical body portion with a rib web construction similar to the lower body portion and the construction of a non-rotatable holder, are also contemplated. These and other numerous changes in construction details are to be considered within the scope of this invention.
