Application March 12, 1954, Serial No. 415,815

4 Claims. (Cl. 242-72 Our invention relates to structuresdesigned to receive strip and wire material, such as steel, and to rotate with the etfect of winding the material into'a roll. Various machines have been devised for this purpose and designed to be adjustable in respect to the original diameter or inner size of the roll to be formed. However, such machines as have come to our attention do not carry a drum which is suitable for the winding of strips 'of different widths, and one object of the present invention therefore is to provide a winding drum which has this advantage.

A further object is to provide a winding drum which is easily mountable on the conventional winding machine and made fast to the machine by the adjustment of the same.

Another object is to design the novel winding drum as a flexible unit which is expansible to render the drum rigid for the support of the work.

An additional object is to construct the novel winding drum along lines of simplicity and easy application to the conventional winding machine.

With the above objects in view, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Fig. 1 is a front elevation of the winding drum as mounted on the winding machine;

Fig. 2 is a view from the right-hand side of Fig. 1; and

Fig. 3 is an enlarged section on the line 33 of Fig. 1.

In accordance with the foregoing, specific reference to the drawing indicates the standard of a conventional winding machine at 10, and the base thereof at 11. The machine has a headpiece 12 which journals a shaft 13; and a gear 14 is mounted on the frontal portion of this shaft. The shaft also carries a suitable bearing 15 for a set of radial screws 16 whose inner ends carry pinions 17 which are in mesh with the frontal side of the gear 14; and the screws carry a set of traveling nuts 18 which are extended forwardly with arms 19. The gear 14 may be made stationary by means of a key or pin 20 passing through the gear hub and into the headpiece 12, or by some other suitable mechanism. In this event, rotating the bearing 15 in order to revolve the screws 16 will cause the pinions 17 thereof to roll around the gear 14 and rotate the screws at the same time. The effect will be the gathering or separation of the arms 19.

Usually, when work is to be wound on the machine, the arms 19 are situated at the proposed internal diameter of the work; and they are separated as just described in order to make the work fast to the set of screws. Then, when the winding is to begin, the pin 20 or other mechanism is withdrawn to release the gear from the headpiece, and the latter made tight to the shaft 13, so that the rotation of the latter will operate the winding assembly as a whole.

The present invention has no operative connection with the mechanism of the winding machine, applying only to the arms 19 thereof. In other words, the invention is intended to be mounted on the said arms and to be made 2,729,403 Patented Jan. 3, 1956 fast on the same when they are expansively adjusted. Specifically, the novel winding drum consists of three basic parts, namely, a frontal plate 25, a back plate 26, and a frontal band 27. The

plates

25 and 26 are of sufficient thickness'to be rigid, yet light enough to enable the winding drum to be carried about readily; and the plates are both of circular form and concentrically arranged.

The

plates

25 and 26 are attached to each other in spaced relation. Thus, Fig. 3 shows a spacing unit employed, the same consisting of a disc 30 which is extended from one face with a shank 31 which is riveted, as indicated at 32, to the plate 26. The thickness of the disc 30 represents the spacing distance for the plates; and the plate 25 is attached to the disc by means of a screw 33 threaded into the disc as shown. Fig. 1 shows that this spacing expedient is employed at six circularly spaced points to hold the plates together evenly.

The

plates

25 and 26 are made with central openings 35 of the same diameter; and the band 27 is positioned in front of the plate 25, and with the rear edge of the hand even with the rear face of the plate. The band is of spring steel and normally contracted to a size materially less than the diameter of the openings 35, so that the ends of the band are closely spaced, as indicated at 36. However, it is possible to expand the band until it fills the opening 35 in the plate 25, so that the wall of the band will lit the plate, as clearly shown in the right-hand central portion of Fig. 3.

The band 27 is fioatingly supported in relation to the

plates

25 and 26 when the band is in the contracted position shown. This support is gained by welding 2. lug 37 to the rear of the drum wall, as shown at 38 in Fig. 3, to dispose the lug 37 in a plane crosswise of the band axis. The ing 37 is made with an opening 39 to receive one of the spacer discs 30, as shown in the figure just referred to, so that the band becomes pivotally supported between the plates in this manner. In order that the drum may not swerve laterally, it is extended with lugs 40 and 41 at points distant or across from the lug 37, such lugs extending from the band into the space between the

plates

25 and 26.

It is apparent that the band 27 is of considerable width, so that it may serve as a winding spool for material which is either narrow or wide. When such service is required, it is only necessary to gather the arms 19 of the winding machine to an extent to be received inside the band 27 as the novel winding drum is backed toward the winding machine 10. The latter then is operated to separate the arms 19, this action expanding the band until it fits tightly in the opening of the plate 25. The winding drum now is rigidly attached to the rotary assembly of the winding machine and may receive the work 50 by having the foremost end of the same hooked over the leading end of the band.

It will now be apparent that the novel winding drum is a highly efiicient mounting for the winding machine. While it requires no operative connection with the mechanism of the same, it becomes a part of the winding machine by simple application to the projecting arms 19 thereof and the expanding of the same to make the winding drum fast. Now, the arms 19 alone are not depended upon to receive the work, but the wide and circular unit 27 is present to receive material of any suitable width, and to form the same into a roll without the need of accurate alinement between the supply zones and the winding drum. Further, the plate 25 is large, offering a corresponding capacity for the work. Further, the large size of the plate 25 also gives it the function of a guard to prevent the material wound from getting in the way of the mechanism of the winding machine. Further, the

provision of the two

plates

25 and 26 not only makes for the rigidity of the winding drum, but also provides a uniform bearing for the

band lugs

37, 40 and 41. Finally, the novel winding drum is made up of parts which are few and simple, so that it may be produced economically and easily handled for application to or removal from any winding machine available for a given job.

While We have described the invention along specific lines, various minor changes or refinements may be made therein without departing from its principle, and we reserve the right to employ all such changes and refinements as may come within the scope and spirit of the appended claims.

We claim:

1. A winding drum adapted for mounting on the expansible arms of a strip or wire windingmachinc comprising a frontal plate, a rear plate spacecily attached to the frontal one, both plates having openings in substantial registration, a band situated forwardly of the frontal plate and being expansible to engage its rear portion with the rim of the opening in the frontal plate, an element attaching the band for free motion at a point between the plates, and other elements extended between the plates distantly from said point for maintaining the alinement of the band with the plates.

2. The structure of claim 1, one spacing means for the plates being a circular disc, and the first element being a lug extended from the band to pivot about said disc.

3. The structure of claim 1, said other elements being lugs extended at points opposite the first element to project into the space between the discs.

4. The structure of claim 1, said elements comprising lugs attached to one end of the band in a plane transverse of its axis.
