MASSACHUSETTS, ASSIGNOR TO THE OF PORTLAND, MAINE.

MANGLE.

Application filed June 23, 1893 Serial No. 78,597. (No model.)

To all whom it may concern.-

Beit known that I, J AMES G. CRAWFORD, of Boston, in the county of Suifolk and State of Massachusetts,have invented certain new and useful Improvements in Mangles, of which the following is a specification.

The object of this invention is to provide an improvement in mangles, which will enable a piece of cloth to be more effectively ironed than heretofore.

To this end, the invention consists in the novel features of construction and combinations of parts described hereinafter and pointed out in the claims.

Referring to the accompanying drawings, which illustrate the invention: Figure 1 shows a side elevation of the machine. Fig. 2 shows a longitudinal section.

The same letters of reference indicate the same parts in both the figures.

In the drawings: The letter (L designates the supporting-frame of the machine which has hearings on its upper side for two cylinders b and (2', around which the cloth is carried. Each of these cylinders is formed of spiders c, and slats c, which have spaces between them to allow the escape of moisture issuing from the cloth under treatment. A covering (7, of felt or other suitable material, is fastened on each cylinder. The cylinders are driven from a shaft a, through gears e e a and both rotate in the same direction. Be-

low each cylinder is supported an arm j, which is hollow, so that steam may be admitted to itfor purposes of heating, and said iron is concavo-convex in form, having a smooth concave face f, concentric with the cylinder and adapted to co-act therewith in ironing the cloth; and a smooth convex under surface f one end of the iron is rounded, as at f so that the cloth may pass readily over this end from the under to the upper side of the iron. The iron is supported in a hearing g, which permits it to rock and adjust itself to the cylinder and the cloth under treatment, and said bearing is fastened on an arm g, pivoted at one end to the frame of the machine. Adjustment of the iron to suit the material under treatment may be effected through a worm 9 having a handle y a segment-gear g in mesh with said worm and carrying a gear 9 and a segment-gear g fast with the arm g and in mesh with said gear 9 It will be seen that, by turning the handle 9 the iron may be lowered or raised, and 5 5 thereby adjusted with relation to the cylinder. An endless apron 7t passes around rollers 71' h 71 in bearings fastened to the ends of the irons f, and engages the convex surfaces of said irons. Theniiddle roller 72. and 6c the roller h are supported above the irons, in close proximity to the cylinders, so that, at these two points, the apron extends from the ends of the iron toward the cylinders, so as to properly guide the cloth. This apron passes from the roller 71., which is located at one side of the iron f, under the convex surface of said iron, and thence over the roller 72 from whence it is carried under the convex surface of the second iron f and over the roller 72. Said apron is carried from the roller 71, downward to and under a roller h, supported in bearings on the machine frame, and thence under a tension-roller h and back to the roller 7K. The tension-roller 71, is carried in bearin gs 7L6, each mounted on a vertical screw-shaft M, which is supported in fixed bearings on the frame. Said screw-shaft carries a wheel 7L8, by which it may be turned and the tensionroller adjusted to regulate the tension of the apron 7L according to the adjustment of the irons.

The operation is as follows: A piece of cloth to be ironed is first introduced between the apron and the under surface of the iron at the right-hand end of the machine, and the said apron, being constantly driven, carries the cloth over the said under surface, at the same time pressing it against the same. The cloth is turned over the rounded end of the iron, as indicated by the arrow in Fig. 2, and then passes back between the concave surface of the iron and the cylinder, and thelatter, being constantly rotated, carries the cloth around with it. The under and upper ironing surfaces of the iron both act on one side of the cloth as it passes around the'iron. After the cloth passes over the top of the cylinder, it is carried therefrom over the apronroller W, as indicated by the arrow in Fig. 2, and thence passes between the apron and the under convex surface of the second iron.

The cloth is carried around the end of the iron, and between the same and the cylinder, as before, and thence passes up over the cylinder, and is carried off over the apron-roller 5 k The close proximity of the rollers 7L2 and h to the cylinders prevents the cloth from returning under the cylinders after passing over them. Guide-plates '5 are hinged in a position to hold the cloth upon the cylinders.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A mangle, comprising in its construction a rotary cylinder around which the cloth passes; an iron supported below the said cylinder, and having a concave ironing surface to co-act with the said cylinder, and a con- \Vitnesses:
