IRONING MACHINE 2 Sheets-Sheet Filed April 13, 1928 INVENTOR Gis T -5ca z'ezd' BY e lub- ATTORNEY gs. T. SCOFIELD IRONING MACHINE Filed April 13, 1928 2 Sheets-Sheet 2 INVENTOR Gilles T s cjyz'efii Patented Aug. 9, 1932 PATENT OFFICE GILES T. SCOFIEL'D, OF ROCHESTER, NEW YORK IRONING MACHINE Application filed April 13, 1928.

The present invention relates to ironing machines and more particularly to the type in which one or more padded rollers feed the work over a stationary ironing surface. An

. object of this invention is to provide a means which will act on the goods being ironed to prevent them from sticking to the rotary roller to hold the goods to the ironing surface.

Another object of the invention is to provide in connection with the stripping means a means which will hold the stripped material in contact with the ironing surface for en gagement with a second padded roller.

To these andother ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described: the novel features being pointed out in the appointed claims.

Fig. One

of a plurality of steam heated sections 1 with concave ironing surfaces 2 separated by con vex surfaces 8. For cooperating with these r concave surfaces padded rollers 4 are provided. Material may be fed by a feeding mechanism comprising a plurality of moving tapes which direct the material 6 to the concave ironing surface 1 beneath a receiving roller 4 from which it is delivered to a second ironing surface 2 beneath a second roller 4 and so on until the material is finally delivered from the machine.

There is a tendency in a machine of this type for the material 6 to follow the rollers 4 and particularly the first roller 4 which operates on the material while the latter is in moist condition. Heretofore, it has been customary to place cords or strings about these rollers 4 in such a manner that the goods are stripped from the rollers and caused to eral use comprises a stationary iron formed Serial No. 269,755.

travel over the ironing surface but these cords or strings because they pass between the rollers and the ironing surfaces produce in the ironed goods ribs or marks conforming to the shape of the cords thus making it impossible to obtain a smooth unwrinkled ironing effect. I

According to this invention a stripping means has been provided which will effective-- ly prevent the material from following the rollers and will at the same time eliminate all possibility of marking or disfiguring the goods.

A means for carrying out this invention comprises a rotary stripper 7 which cooperates with the first padded rotary roller 4 adjacent the point where the latter passes out of contact with the concave ironing surface 2 and which has a peripheral rotation in the direction opposite to the peripheral rotation of the roller 4. In this instance, this rotary stripper is in the form of a rotary brush, the shaft 8 of which is supported by a rod 10 by means of bracket arms 9. The rod 10 is supported at opposite ends by brackets 12 bolted at 13 to the side frames 14 of the ironing machine and to this end a rod 10 has at each end laterally extending plates 15 which by bolts 16 and a slot 17 may be adjusted to ralse and lower the rod 10, in order to move the rod toward and from the ironing surface. The arms 9 are also adjustable about the rod 10 at an axis through the medium of split clamps 17 which permit the brush or stripper 7 to be moved toward and from the roller 4. Rotation of the brush 7 may be effected by a pulley 18 on the shaft of the brush cooperating with a belt 19 which is driven by a pulley 20 on the shaft of the next roll-er 4.

In addition to stripping the goods from the first roller 4 means may be provided which will coact with the stripper to strip the goods from the latter and at the same time direct them toward the convex ironing surface so that they will travel toward the second roller 4. This means, in this instance, may comprise a plurality of endless flexible belts 20 made of any suitable material and passing about pulleys 21 journalled on the shaft of the brush 8 at spaced points throughout the length thereof. From the brush the belts pass over the convex surface of the iron to rollers 22 situated in close proximity both to the ironing surface and to the peripheral surface of the second roller 4 but spaced from the latter. In this instance, these rollers 22 are arranged on a shaft 23 which is supported by a plurality of arms 24 adjustably secured by split clamps 25 to the rod 10. From the rollers 22 the belts 20 pass over the pulleys 26, theperipheries of which engage the secondfeeding roller 4. These pulleys 26 are supported on shafts 27 by means of bracket arms 28 fromthe tubular rod 10 and are held in proper positions against the second roller 4 by set screws 29. ,After passing over the pulleys 26 the belts pass over pulleys 30 on shafts 31 supported by bracket arms 32 from the shaft 10.

From the pulleys 30 the belts pass again to the pulleys 21 on the brush shaft.

It will thus be seen is stripped off the first roller 4 by the brush or stripper 7 and is then engaged by the belts 20 and held against the ironing surface until a point near the second roller l is reached. The latter then takes up the goods and may also have another stripper mechanism like that herein disclosed associated therewith to direct the material to the next roller. .The belts, 20 travel at'the same surface speed as.

the rollers 4 and in this way assist in feeding the goods as Well as holding such goods to the ironing surface between the rollers.

What I claim as my invent-ion and desire to secure by Letters Patentis:

1. The combination with an iron having two concave surfaces and an intervening convex surface, and two padded rolls arranged above the iron and cooperating with said concave surfaces, of a plurality of endless belts arranged bet-ween the two rollers and each having a portion conforming to and engaging the convex surface between the two rollers, all portions of the iron engaged by the belts being situated between the rollers, and means for driving said belts at a surface speed corresponding to the surface speed of said two rollers.

2. The combination with an iron having a concave ironing surface and a surface beyond said concax e surface and a padded roll arranged above the iron and cooperating with said concave surface, of a rotary stripper having its periphery operating in a direction opposite to the direction of'movement of the that the material 6- them and also the goods adjacent the convex surface and directingand holding the goods against the convex surface for travel to the other roll.
