3 Claims.

This invention relates to ironing machine rolls and more particularly to' the provision in an ironing machine roll of an extension at one end that will support; articles being ironed projecting beyond the end of the roll and thus prevent such articles becoming wrinkled.

It has been found, while ironing large pieces on an ironing machine of small size having one or both ends accessible, that the ironed piece is allowed to project over the end of the roll. In so doing the ironed piece becomes wrinkled as it bends over the end of the roll.

Among the objects of my invention is to overcome the above objections, and provide an iron- 16 ing machine roll whose article supporting length may be increased or decreased at the will of the operator.

Other objects, advantages and capabilities will later more fully appear.

so My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment, I wish it understood that the same is susceptible of modification and change without departing from the spirit of my invention.

In the drawings:--

Fig. 1 is a side elevation of an ironing machine showing in dotted lines my extension for the roll II) in partially extended position.

Fig. 2 is a fragmentary side elevation of the ironing machine roll showing my improved ex-. tension extended to a greater degree than in Fig. 1.

III Fig. 3 is an end elevation of the ironing machine shown in Fig. 1 and looking toward the end of the roll to which my extension is applied.

Fig. 4 is a. longitudinal cross-section, partly broken away, of the ironing machine roll and my 0 improved extension therefor, the extension being shown in its fully extended position.

Fig. 5 is a fragmentary longitudinal sectional view similar to Fig. 4, but showing the extension as being pushed into the ironing machine roll.

Fig. 6 is a transverse section taken on the line 66 of Fig. 4.

In order to prevent the wrinkling or otherwise mussing of the ironed pieces, particularly the larger pieces, such as sheets, tablecloths and the like, I have devised and shown in the accompanying drawings an extension at the end of the roll that supports the projecting portion'of the ironed pieces in a substantially straight and continuous line with the main roll, and which supports and carries the ironed work without wrinkling. As such an extension would be in the way when smaller pieces are being ironed, I have so formed this extension that it will be preferably collapsible or telescopic with the main roll so that it may be pulled out or pushed in at the 5 will of the operator and varied as to length within the limits of its adjustability.

Referring in detail to the drawings, the main roll I is provided with semi floating mounting, the idle head 2 revolving on the supporting tub- 1o ing 3, the ironing machine roll being secured to the idle head 2 in any suitable manner. Also fixed to the interior of the hollow ironing machine roll and at a point inwardly from the idle head 2, is the drive head 4 which is fixed to the 15 drive shaft 5, which drive shaft is in turn supported by the journal 6 at the inner end of the supporting tubing 3.

The drive head I is preferably positioned a sufficient distance inwardly from the free end of the roll I to provide the necessary room for the telescopic roll-extension attachment, which is designated generally as A, and which in the form illustrated in the drawings comprises two cylindrical sections I and 8, the latter being telescopically mounted in the former.

The ironing machine roll I is provided at its extreme end with the annular ring 9, which reinforces the roll at that end and also serves as a guide for the telescopic roll extension. This ring 9 is only optional as it is apparent that the extension could slide directly in the cylindrical shell of the main roll or in any other suitable form of guiding means therefor. The annular ring 9, as shown, is provided with an annular recess I0 into which the top cover cloth II of the roll may be tucked and secured, and thus the cover cloth be kept out of the operating way of the telescopic extension. I

Sections 7 and 8 are provided with tapered portions I2 and I3, respectively, which, as seen in Fig. 4, cooperate to prevent section 8 from being pulled entirely out of section I and also to eliminate looseness of these parts when in extended position. Section 1 is provided with a 5 stop spring I4 (see Figs. 4 and 6) which, when section I is pulled to its outer limit, will contact with the annular ring 9 to prevent section I from being entirely removed from the main roll I. If it is desired to entirely remove section 1 from the main roll this can be accomplished by bending the spring stop inwardly until it clears the inner edge of the annular ring 9. This bending of stop spring I4 may be accomplished manual y or by any other suitable means.

Section 8, as shown, is provided with a flange l5 projecting sufiiciently beyond the diameter of section 8 to limit the closing travel of this section which, as seen in Fig. 5, will be accomplished by reason of flange l5 striking flange I6 of section I, flange 16 in turn striking the annular ring 9. Flange i5 of section 8 has an opening of smaller diameter than the interior diameter of section 8, thus providing an available hand-hold to enable the extension sections to be pulled outwardly into extended position.

While my extension device is shown in the drawings as consisting of two sections, it will be readily understood that the same could consist of any other number of sections as desired, and when more than two sections are used similar tapered portions l2 and I3 may be provided for the various sections to operate in a similar manner to those-shown in connection with sections 1 and 8.

Having now described my invention,

I claim:-

1. In an ironing machine roll having a hollow interior and an open end, a tubular extension slidably mounted in the hollow interior and movable in one direction into the roll, and in the opposite direction to project outwardly therefrom, and a stop member adjacent the inner end of the tubular extension to limit the extent of its outward movement, said stop member comprising a normally sprung out finger movable inwardly when desired to entirely remove the tubular extension from the roll.

2. In an ironing machine roll having a hollow interior and an open free end, a tubular extension longitudinally slidable inwardly and outwardly of the roll, an inwardly projecting stop projection within the open end of the roll, and a normally outward sprung finger adjacent the inner end of the extension to normally limit the extent of outward movement of the extension, said finger being movable radially inwardly of the extension to clear the stop projection of the roll to permit the extension to be entirely removed from the roll when desired.

3. In an ironing machine roll having a hollow interior and an open end, an inwardly extending annular projection in said open end, a tubular extension telescopically slidable in the hollow in- I
