BOBBIN HOLDING MEANS Filed Feb. 14, 1945 INVENTOR ATTORNEYS Patented Apr. 12, 1949 UNITED S TAT ES ram orrlcr:

BOBBIN HOLDING .MEANS Burt A. Peterson, Rockford, 111., assignor to Bar-- her-Colman Company, Rockford, 111., a corporation of Illinois 12 Claims. 1

The .invention pertains in general to bobbin holders for use in textile mills, and has for a general aim the provision of bobbin holders for use with automatic bobbin winding machines in which the dolfed bobbins are delivered directly to holders each adapted to support a group of bobbins whereby to facilitate handling of the bobbins.

In a more specific aspect the invention pertains to bobbin holding means of the pin board type and provides a plurality of individual holders for mounting upon a convenient supporting and carrying frame so as to form a sectional pin board.

With the foregoing in view, an important object of the invention is to provide a bobbin holder in the form of an elongated slide equipped with a series of supporting pins and constructed and arranged to be supported for sliding movement relative to suitable supportin and guiding means whether the latter form a part of a bobbin winding machine or a portable supporting and carrying frame.

A further object is to provide a bobbin holder of the character indicated which is light in weight yet strong, rugged and durable and capable of being manufactured at a low cost.

Another object is to provide a pin board comprising a supporting frame and a plurality of bobbin holders each adapted to receive and support a plurality of bobbins and constructed and shown by way of illustration in the accompanying drawings forming part hereof wherein I have shown a plurality of bobbin holders forming a part of a sectional pin board. The application of the holders to guiding and supporting means forming a part of a bobbin winding machine is disclosed and claimed in my copending application Ser. No. 577,865, filed February 14:, 1945.

In the drawings, Figure 1 is a perspective view of a sectional pin board embodying my invention.

Fig. 2 is a fragmentary transverse sectional detail view showing detent means yieldably retaining bobbin holder slides in position on the supporting frame of the pin board.

Fig. .3 is a transverse longitudinal section taken approximately in the line of of Fig.

Fig. 4 is a fragmentary detail view in plan illustrating the operation of placing a bobbin holder slide onto the supporting frame.

In the present exemplary embodiment of the invention a plurality of the novel bobbin holders l are shown for use with or mounting upon acornmon supporting frame 8 to form a sectional ,pin board. Each holder comprises an elongated slide 9 made of sheet metal and consisting of .a .flat narrow plate or bar with flanged opposite edge portions providing slide members Ill preferably shaped to form opposed grooves or channels l.l.. These edge portions perform the added function of stiffening and strengthening the slides thereby permitting the use of metal of relatively light gauge which is desirable both from the standpoint of cost and weight.

Each slide is equipped with a series of bobbin supporting elements or devices herein in the form of pins 92 mounted in uniformly spaced parallel relation along the slide bar centrally thereof. .As shown in Fig. 3 the pins are preferably made hollow .or tubular for the sake of weight reduction and each comprises a base portion I3 and a tip it of relatively smaller diameter. The base portion it of the pin has .an external bore fitting relatively snugly with respect to a metallic .sleeve It with which the butt ends of the bobbins .are

commonly equipped. 7

The pins are advantageously mounted in the slide bar 9 by a swag-ing operation. For this purpose countersunk holes are formed along the bar, and annular flanges l6 projecting axially from the base portions l3 of the pins are inserted through the holes and then expanded outwardly into firm binding engagement with the slide :bar. In such expansion of the flanges IS the shoulders ll of the pins are drawn downwardly toward the slide bar and this action is utilized to clamp bobbin retaining clips t8 firmly in position. Each clip is made from a thin piece of sheet metal to form an apertured base 19 which is interposed between the pin shoulder H and the top face of the bar. [it end the base it carries an upright arm ill for yieldab'ly engaging between adjacent rings 2! on the bobbin. To position each clip relative to the slide, a lug 22 depends into a slot 23 in the bar.

The supporting frame "8 is constructed :to provide guide members 24 for interfitting engagement with the slides, and in view of the channel formation of the slide members ill the guide members are in the form .of flat flanges protruding outwardly from channel shaped guide bars 25. The latter also constitute frame members, being rigidly secured as by welding to cross frame members 26 which are likewise of channel form for stilfening and strengthening purposes. It will be observed that the .fianges in addition to forming the guide members 24 lend strength and rigidity to the frames.

To facilitate movement of the slides onto the frame bars 25 the ends of the slide members I 9 may be cut back a short distance from the ends of the slide bars as indicated at 21 so as to reduce the width of the ends of the slide bars substantially to the width of the guide bars. Also the bottom sides of the channels I I may be rounded slightly as shown at 28 for coaction with the ends of the upright channel walls of the guide bars in guiding the slides onto the guide bars.

To enable the bobbin holders to be set on end without resting upon or interfering with the end bobbins, the slides are preferably provided at opposite ends with rests in the form of flanges 29 integral with the top plates 9 of the slides. These rests are of special utility in the use of the holders in automatic bobbin Winding machines, as disclosed in my said copending application.

For purposes of retaining the holder '1 yieldably in position upon the frame 8 each slide is provided with a block 30 (Figs. 2 and 3) for coaction with a spring detent 3| on the supporting frame. The block is rigidly fastened to the underside of the slide bar centrally thereof and is recessed to receive a ball 32 mounted in a cup 33 and urged outwardly by a spring 34. The cup 33 may advantageously be located within and therefore protected by the channelformation of the intermediate ones of the cross bars 25.

It will be seen that my invention provides bobbin holders especially adapted for use in the transfer of bobbins in groups from a bobbin winding machine to a storage device such as a pin board. Since the Wound bobbins are supported in a single row upon individual holders they are capable of easy and convenient inspection. Moreover, such holders provide for the easy handling of the bobbins without the necessity of touching the same which is a substantial advantage especially in the case of rayon yarn or other filament yarns. Finally, the particular construction employed provides a pin board of light weight yet very rugged and durable.

I claim as my invention:
