Patented May 6, 1930 UNITED STATES PATENT OFFICE STMDN HENRI STOFFEL, OF DELFT, NETHERLANDS, ASSIGNOR '10 MACHINEFABBIEK REINEVELD. OF DELFT, NETHERLANDS, A COMPANY OF THE NETHERLANDS LAUNDRY IRONING MACHINE Application filed December 22, 1927. Serial No. 241,951.

This invention relates to laundry ironing machines or mangles of the type wherein a clothed roller is associated with a heated concave polishing bed in which it rotates.

The main object of this invention is a construction in which no special means are required for causing the goods to disengage the roller at the delivery side of the machine, and with this object in-view I suggest to apply suction to the exterior of the roller by dividing the polishing bed into compartments and connecting one or more of these compartments with the suction side of the exhauster, other compartments serving as usual for the circulation of the heating medium. By these means I attain that thesuction of the exhauster tends to disengage the goods from the roller so that the articles are readily delivered without manual assistance or special mechanical appliances.

Another object of my invention is to' in crease the polishing surface of the bed without interfering with the easy mounting of the roller. This may be realized, in accordance with my invention, by dividing the polishing bed into segmental sections adapted to be mounted separately so as to conjointly form a bed which encircles the roller through an an ular distance of more than 180.

Either objects of my invention will appear from the following description of the ironing machine diagrammatically shown, by way of example, on the annexed drawing, which ,illustrates a side elevational View, partly a cross sectional view thereof.

On the drawings, 1 is the frame of the machine, 2 the roller adapted to be rotated by some conventional means, 3 the blanket -or equivalent with which the roller is covered.

The polishing bed is composed of a plurality of segmental sections 4, 4 4", 4 each comprising one or more suction compartments 5 in addition to one or more heating compartments 6. The suction compartments 5 have their polishing faces perforated, the perforations being designated by 7 whereas the polishing faces of the heating compartments 6 are impervious, as usual. The compartments 5 are connected to the suction side of an exhauster, not shown, compartments 6 having connections with a heating steam supply pipe and a; waste steam pipe, as usual.

- In the example shown, the suction compa rtment of cach section 4, 4 4 4 is at the leading or inlet end thereof as viewed in the direction of rotation of the roller indicated by the arrow 8, the last section 4 being, moreover, provided with a suction compartment at the delivery side of the polishing bed. It will thus be seen that the goods, in the normal course of rotation, easily enters into the space between the clothed roller and the polishing bed, also at the gaps or joints between two adjacent sections of said bed, and that at the delivery end of the machine it will under the influence of the suction created by the last roller and its associate covering where the heating boxes 6 are not effective to mitigate the tendency for vapour to be condensed in the clothing owing to the removal of heat by the entering cool air.

What I claim is 1. In a laundry ironing machine, a clothed roller, a circular series of segmental sections together forming a concave polishing bed in which said roller is adapted to rotate, a circular series of compartments formed in said sections, means for creating suction, means for supplying heat, means for connecting said suction creating means with recurrent compartments, means for connecting said heat supplying means with the remaining compartments, and perforated face plates for the compartments connected with the suction applying means.

2. In a laundry ironing machine, a clothed roller, a circular series of segmental sections together forming a concave polishing bed in which said roller is adapted to rotate and extending through an angular distance greater than 180, a circular series of compartments formed in said sections, means for creating suction, means for supplying heat, means for connecting said suction creating means with recurrent compartments, means for connecting said heat supplying'means with the remaining compartments, and a perforated polishing face for the compartments connected with the suction applying means. I

3. In a laundry ironing machine, a clothed roller, aplurality of segmental sections together forming a concave polishing bed in which said roller is adapted to rotate, partitions in said section's dividing the same into compartments lying side by side in circumferential direction, means for applying suction to the leading compartment of each section and to the compartment at the delivery side of the polishing bed, perforations in the polishing face of said suction compartments, and means for heating the remaining compartments.

4. In a laundry ironing machine, a clothed I roller, a concave polishing bed in which said roller is adapted to rotate, partitions dividing said bed into a plurality of compartments, means for applying suction to certain of said compartments, the compartments to which suction is a plied having perforations in their polishing aces, means for applying heat to the remaining compartments, and means for heating the roller.

5. In a laundry ironing machine, a clothed roller, a circular series of independent segmental sections together forming a concave polishing bed in which said roller is adapted to rotate, spaced apart compartments formed on the segmental sections with their polishing. faces perforated, means for applying suction to the compartments, and means for supplying heat to the segmental sections between the spaced apart compartments.

In testimony whereof I aifix my signature.

SIMON HENRI STOFFEL.
