apinieation mea August 14, 1924. serial No. 731,925.

, My invention relates to ironing machines and it has special relationlto ironing machines of the domestic type.

' An object of my invention is to provide a device that shall make convenient the ironing-of large pieces on small ironing machlnes. s

A further .object of my invention is to provide a device adapted for use in the ironing of large pieces in an ironing machine, for supporting and advancing that portion of an article to be ironed which extends beyond the end of the machine, in correspondence. with the advancement ot that .part ofthe article which is being ironed.

Other objects 'of my invention will appear'` as the description proceeds.

Referring to the drawing:

Figure 1 is a .rear elevational view of an ironing machine with my invention applied thereto.

Fig. 2 is a longitudinal central sectional view of the roll shown in Fig. 1.

D Fig. 3 is adetail sectional view of the roll and cooperating parts, portions being brokenl away, and

Fig. 4 is a' view of the right end of the roll, parts being broken away to facilitate illustration. Y

An ironing machine embodying my invention comprises a roll 1, a shoe 2 and standards?) and 4 for supporting the roll and the shoe. Instead ofthe shoe, a heated roll may be used if desired.

The ends of the roll 1 are mounted on a pair of spiders 5 and 6 that are secured to a longitudinal -shaft The end of the roll at which the spider 5 is provided, has no immediate support other -than the spider 5 and the shaft 7. It is of thetype commonly referred to in the art: as open Each of the spiders 5 and 6 is provided with a plurality of holes 8, each hole of one spider being connected to a corresponding hole of the other by an 'elongated tube 9. The tubes-9 may be of' any desired number and are adapted to receive slidable tubes 10 which are secured to a head 11.

limited by stops, 12 thereon which engage detachable stops 13 in the tubes 9. Y

Tubes 14 rigld with a head 15, are slidable in the tubes 10 but limited in their outward port for articlesI Outward movement of the tubes 10 ismovement by stops 16 which engage detachable stops 17 'in the tubes 10..

COMPANY, A CORPORATION OF PENN- When small pieces are being ironed, the

tubes 10 and 14 are of the roll'v 1, being completely enclosed thereby, as indicated by dotted lines in Fig. 3. hen comparatively wide pieces are being ironed, the heads are drawn outwardly to the position shown in' full lines in Figs. 1, 2Kand 3. The articles are then passed between the roll 1 and the shoe 2 and those portions of the articles which are not positioned interiorly subjected immediately to an ironing action by the shoe 24 are supported and' carried by.

the tubes 1() and 14.

When an article is draped over the tubes 10 and 14, it is given a semi-cylindrical shape conforming substantially to the shape imparted to that portion of an article which is on the roll. It is not necessary in order to impart a semi-cylindricalshape that the tubes 10 and 14 should be of the specific number illustrated. It is apparent, therefore, that wrinklingfof that art of the article which is beyond the en of the roll is avoided. l

In addition to preventing wrinkling, the tubes facilitate the feeding of large pieces by reason of the fact that; n`o special care portions of the pieces end of the roll, since need be taken of those which are beyond the they are carried by thetubes and advanced in correspondence with thev portions that are on the roll.

If desired, the tubes 14 need not be moved outwardly with respect to the tubes 10 but the tubes^10 only may be utilized as a supbeing ironed.' Again, if desired, the tubes 10 and 14 and heads 11 and 15 may be dispensed with altogether, as the detachability of the stops 13 and 17 permits their removal.

In the case of an 18 roll, the tubes 10,'in their extended positions, ma be made to v project 12. beyond the end o the roll 1, 4

tubes 10 during the rotation of the roll. 4In a machine of these dimensions, the tubes 14 may have a corresponding and` proportional length with respect to the tubes 10. In they case of an ironing machine having a 30 roll, the tubes 10 only are .1 2 ry, as suplsively modified and varied without departing fromthe spirit of the invention. For instance, Instead of the extensible tubes, any support maybe used that is adapted to rotate with and telescope in, the roll. Again, a'

support may be used whichl does not telescope with the roll but is attached ythereto and removable therefrom. A substantial range of equivalents is contemplated within the scope of the4 appended claims.

I claim as my invention:

1. In an ironing machine, in an ironinv roller and a Work support carried by the rol said Work support being disposed in telescopicrelation with the roll. i

2. The combination of a heated ironing member; a roll having an open end, and extensible means projecting from the open end of said roll, and movable therewith for supporting and advancing an article to be iro'ned, said means. being operative to supcombination, i

portisaid article in. substantially theV same shape. as that portionof the article between said member and said roll.

3. The combination of a heated ironing` member, a roll, and extensible means ron said -roll for supporting and advancing an article to be ironed.

4. The combination with a heated ironing member and a roll cooperative to perform ironing operations, of means movable to be completely enclosed. by saidl roll and extensible to pro]'ect beyond said ro'll for supporting that portion of said article which is not immediately subjected to ironing action.

5. In au ironing machine, the combination with the heated ironing' member and a roll cooperative lto perform ironing operations` of a member extensible with respect to said roll Iand an additional mem'ber extensible with respect to the first mentioned extensible member, the two .last mentioned members being adapted to support that portion of jected to ironing action.

5o .said article which is not immediately sub- In testimony whereof, I havel hereunto A subscribed my name this 2nd day of August,

RALPH HRENFELD.
