MANGLE.

Specification of Letters Patent.

Patented July 26', 1921.

Application filed February 28, 1921. Serial No. 448,327.

To all whom it may concern:

Be it known that I, JAMES Nonnm, a citizen of the United States, residing at Quincy, county of Norfolk, Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Mangles, of which the following is a specification, reference being had therein to the accompanying drawings. i

The invention relates to a new and useful improvement in mangles for use in ironing fiat goods such, for instance, as sheets, pillow cases, towels, etc. The object of the present invention is to provide a simple device having an apron on which the article to be ironed is fed and pressed by being rolled up around a roller inside of the apron. In some mangles, the article together with the apron is drawn betweentwo rolls and removed at the opposite side after having been drawn through the rolls, and in some cases, the rolls have been reversed and the articles brought back again to the front side of the machine, but the outer end of the apron has hung loose; In other cases, an endless feed apron is employed and the article is carried by the feed apronaround between two rolls and back again. By still another method,

the article is wound up. with the apron around one of the rolls and then drawn out again by reversing the direction of rotation of the rolls, and the end of the feed apron on the operative or feed side of the machine either hangs down free or rests on a table and has no takeup for the apron on the reverse movement. My invention consists in the use of a single apron and two rolls, one of the rolls being at some distance in front of the other, one end of the apron being connected with one of the rolls and the other end of the apron being connected with the other roll. Means are provided whereby the rolls are positively rotate-d so as to unwind the apron fromone roll onto the other in the forward action of the machine, carrying the article with it and winding it around inside the apron on the takeup roll, keeping the apron taut all the time and pressing the article as it winds around the takeup roll inside the apron. Means are also provided by which both rolls may be positively rotated in the reverse direction so that the apron will be unwound from the takeup roll and Wet- 1d p again on to t e f r01 thereby bringing the article back again to the front and keeping the apron taut during the entire forward and reverse movement.

7 The invention will be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof Will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a side elevation partly broken away of a machine embodying my invention.

Fig. 2 is a plan view of the machine shown in Fig. 1-.

Referring now to the drawings, 1 represents what I term the feed roll and 2 the takeup roll. The feed roll 1 is mounted on a shaft 3 journaled in bearings in the side members 4 and 5 of the frame. The takeup roll 2 is mounted on a shaft 6 also journaled in the side members 4 and 5 of the frame. An apron 7 is connected at one end with the feed roll 1 and is connected at the other end with the takeup roll 2. By rotating the roll 2 in one direction, it will unwind the apron from the roll 1 onto the roll 2, and by rotating roll 2 in the reverse direction, it will wind the apron back onto the feed roll 1. The articles to be mangled are placed on the apron 7 at the front, that is, the left-hand side of the machine as viewed in Fig. 1.

Means are provided whereby both rolls 1 and 2 are positively rotated in the same direction either forward or back as desired. The method for operating the rolls is as follows :-The shaft 6 is extended through the side wall 4 of the frame and has mounted thereon a spur gear wheel 8. A pinion 9 is mounted on a stud shaft 10 projecting from the frame 4, said pinion meshing with the gear 8. The shaft 10 is provided with a crank 11 by which it may be rotated, thereby rotating the spur gear 8 and the roll 2. Preferably, the pinion 9 is much smaller in diameter than the gear 8, for instance, in about the ratio of one to five, so as to gain in power.

On the opposite end of the shaft 6 outside of the frame member 5 is mounted a gear 12 a sprocket 16 is mounted on the shaft 3 on the same side of the frame as the spur gear 12. A chain 17 runs over said sprockets 15 and 16.

The two side members 4 and 5 of the frame are suitably connected and braced so as to form a rigid frame. Preferably a cross board or table 18 is provided which is secured to the two side members 1 and 5 underneath the run of the apron 7, said cross board serving not only to connect the two side walls and stifien the frame, but also serving as a support for the apron 7 if at any time it should sag and drop. Its forward end, as will be seen by Fig. 1, extends only to a point somewhat back of the feed roll 1 so as not to interfere with the apron.

It will thus be seen that if the crank 11 is turned to the right, that is, in a clockwise direction as viewed in Fig. 1, the pinion 9 which turns in the same direction, will cause the spur gear 8 to rotate counter clockwise and thereby rotate the takeup roll 2 counter clockwise. causing the apron 7 to wind around the roll 2 and unwind from the roll 1. At the same time, the spur gear 12 on the opposite end of the shaft 6 will rotate in the same direction as the takeup roll 2 and will thereby positively rotate the spur gear 13 in a clockwise direction, thus causing also the sprocket wheels 15 and 16 and the roll 1 to rotate in a direction to positively feed the apron 7.

The crank 11 will be turned over to the right to feed the article forward and roll it up with the apron around the roll 2 for as many wrappings as desired; then the crank will be turned in the reverse direction, that is, to the left, as viewed in Fig. 1, which will reverse the direction of rotation of the roll 2 and the'roll 1, and the apron will be rewound around the roll 1, being kept taut all the time. The roll 2 will thus be positively rotated in the reverse direction by means of gear connections 9 and 8, and the roll 1 will also be positively rotated by reason of the gear "and sprocket connections previously described.

at I claim is 1. A mangle having a feed roll and a takeup roll parallel with each other, onein' advance of the other, a carrier web of sheet material which pays off from the feed roll to the takeup roll, and carries the article to be mangled, winding it up with the web around the takeup roll, and means for positively rotating the two rolls, simultaneously.

2. A mangle having a feed roll and a takeup roll parallel with each other, one in advance'of the other, a carrier web of sheet material which pays off from the feed roll to the takeup roll, and carries the article to be mangled, winding it up with the web around the takeup roll, and means for positively rotating the two rolls simultaneously in opposite directions to each other.

3. A mangle having a feed roll and a take up roll spaced apart from each other, a carrierweb of sheet material which pays off from the feed roll to the takeup roll and carries the article to be mangled, winding it up with the web around the takeup roll, and

means for positively rotating both rolls simultaneously, said actuating mechanism being capable of being operated to reverse the direction of rotation and to positively unwind the web from the takeup roll back onto the feed roll. I

4. A mangle having a feed roll and a take-- up roll spaced apart from each other, a carrier web comprising a single sheet of material which pays off from the feed roll to the takeup roll and carries the article to be mangled, winding it up with the web around the takeup roll, and means for positively rotating both rolls simultaneously in opposite directions to each other, said actuating mechanism being capable of being operated to reverse the direction of rotation and to positively unwind the web from the take up roll back onto the feed roll.

5. A mangle having a feed roll and a takeup roll spaced apart from each other, a carrier web which pays off from one roll onto the other roll and carries the article to be mangled, winding it up with the web around the takeup roll, driving mechanism for posi tively rotating said takeup roll, driving mechanism connecting the takeup roll with the feed roll whereby the rotation of the takeup roll positively rotates the feed roll,

causing the web to be paid off from the feed roll and wound up on the takeup roll and maintained in a taut condition, the driving mechanism for the takeup roll being capable of being reversed so as to rotate the takeup roll in the reverse direction and positively feed the web backward and'rewind it on the feed roll.

6. A mangle having a feed roll and a take up roll whose axes are parallel with each other, the axis of the takeup, roll being for ward of the feed roll and at a somewhat higher elevation, a carrier web which pays off from the feed roll and windsonto the takeup roll and carries the article to be mangled, winding it up with the web around the takeup roll, means for positively rotating both rolls simultaneously in opposite 7directions to each other, the takeup roll rotating up over toward the front during the from one roll onto the other, and carries the article to be mangled, winding it up with the Web around the takeup roll, a crank having driving connection with one end of 5 the takeup r011 shaft whereby the said takeup shaft may be positively rotated at will in either direction; and positive driving connection between said takeup roll shaft and feed r011 shaft whereby the rotation of the takeup shaft positively rotates the feed r011 shaft 10 in the opposite direction to that of the takeup roll shaft.

In testimony whereof I aflix m signature.

JAMES ORRIE.
