' FASTENING MEANS FOR IRONER ROLL COVERS Filed March 8, 1952 INVENTOR.

JACK A. SKELTON BY a fdwz ATTOENEY Patented June 16, 1953 FASTENING MEANS FOR IRONER ROLL COVERS Jack A. Skelton, Atlanta, Ga., assignor to Southem Mills, Inc., Atlanta, Ga., a corporation of Georgia Application March 8, 1952, Serial No. 275,585

6 Claims.

My invention relates to ironer rolls for use in mangles and more particularly to an improved fastening means for securing the pad and pad cover to the ironer rolls.

The use of asbestos cloth as an ironer roll cover has introduced a definite problem in satisfactorily securing the cover to the roll, because the asbestos cloth cannot be easily removed if it is glued to the roll; and although several other methods have been proposed andnumerous mechanical means devised, all of them have proved to be unsatisfactory both from the standpoint of results obtained and the complexity of installation.

It is therefore an object of my invention to provide a means by which an asbestos cover may be secured to an ironer roll satisfactorily.

Another object of my invention is to provide a means which will secure both the pad and pad cover to the ironer roll without the use of tools or lead cloth.

Still another object of my invention is to provide a means for fastening a pad cover to an ironer roll regardless of the type of material from which it is manufactured such as asbestos, cotton, etc.

A further object of my invention is to provide mechanical means of fastening a pad and pad cover to an ironer roll that is simple and inexpensive to manufacture and install, and whereby the pad is held securely in place without the necessity of gluing.

Other and further objects and advantages of my invention will become apparent from the following disclosure when taken in conjunction with the accompanying drawings in which like characters of reference designate corresponding parts throughout the several views, and wherein:

Fig. 1 is a perspective view of a device embodying my invention.

Fig. 2 is a perspective view showing the relative relationship of the parts at the start of installation.

Fig. 3 is an exploded perspective view.

Referring now in detail to the embodiment chosen for purpose of illustration, numeral I denotes a cylindrical iron roller found in conventional rotary ironers or mangles. The roll I0 is customarily mounted for axial rotation on shaft I0. Threadably engaging the outer periphery of roll ID are a plurality of studs II which are spaced along a plane parallel to shaft I 0 to provide a means for attaching the remaining structure to the roll.

As shown in Fig. 3, a thin rectangular fastening bar I2, which corresponds in length and curvature to roller I0, is provided along one of its longitudinal sides with a plurality of spaced lugs I3 which correspond in their spacing to the spacing of studs I I. Lugs I3 are made integrally with bar I2 and are provided with keyhole apertures M to selectively engage or disengage their respective studs I I as illustrated in Fig. 2 and Fig. 3.

From Fig. 3, it can be seen that the flexible asbestos sheet cover I5 is provided with spaced slots l5 adjacent its leading end. Slots I6 are of such shape and spacing that lugs I3 may be inserted through these respective slots I6 so that cover I5 may be folded around and be retained by bar I2, as illustrated in Fig. 2. Padding material I! is inserted between the cover I5 and roll Ill, and cover I5 is wrapped around roll it and over pad I! until the abutting ends of pad H are covered, suificient overlap of cover I5 being allowed to permit spring retainer I8 which engages reinforced holes I9 in cover I! to maintain the proper tension on cover I! to prevent unwrapping. Reinforced holes I9 into which spring I8 is engaged are so positioned that the length of the arc between them, measured from the end of cover I5 in the direction of wrapping, is less than one-half the circumference of the roll, hence the spring I8 will tend to tighten the wrapping regardless of whether it is connected directly between the holes or made to pass around shaft ID as shown in Fig. 1. Cover I1 is wrapped to correspond to the direction of rotation of the roll l0, indicated by arrows in Figs. 1 and 2, thereby tending to tighten the cover I'I while the roll I0 is in motion. From this, it is obvious that the keyhole slots I 4 must be positioned with the smaller dimension toward the outer end of lugs I3 to hold lugs I3 in looking contact with studs II.

It is to be remembered that while a specific number of studs II, lugs I4 and slots I6 has been shown, the actual number is a matter of choice and dependent upon the length of roll In.

From the foregoing description, it will be seen that the pad I! and pad cover I5 are simultaneously affixed to the roll I 0 in a simple yet effective manner which may be accomplished without the use of any tools. It will also be apparent that the type of material from which the pad cover I5 is made does not affect the fastening means.

It will be obvious to those skilled in the art that my invention provides a needed article of great convenience and usefulness, and that while I have illustrated and described my invention in a very practical embodiment thereof, various changes and adaptations may be made without departing from the scope of my invention as de fined in the appended claims.

I claim:
