Application filed. June 27,

T 0 all who-m it may concern.

Be it known. that we, JOHN H. D'UMBLn'rox and EDWIN C. LINDBERG, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful. Improvements in Self-Adapting Sleeve Stretchers, of which the following is a specification.

This invention is a self-adapting sleeve roller, and consists of the novel features herein shown, described and claimed.

An object is to make a self-adapting spring operated device for insertion into a sleeve of a coat or the like to stretch and hold the sleeve while the sleeve, is being steamed or otherwise operated upon, and adapted to form rolled edges instead of creases.

In our self adapting sleeve stretcher we utilize two curved members with leaf springs between. The leaf springs which are attached to the convex member are slightly longer than those connecting the concave side of the stretcher. By this construction when the two parts of the stretcher are pulled slightly apart, the springs will force them wide apart and when they are pressed together so that the long spring passes beyond its center or supporting line, it is bent backwards and the action of the springs is to hold the two sides of the stretcher to gether.

Other objects and advantages will appear from the drawings and specification.

The drawings illustrate the construction and operation of a self-adapting sleeve roller embodying the principles of our invention.

Figure 1 is a side elevation of the selfadapting sleeve roller collapsed for insertion into a sleeve and for handling, as in packing and shipping.

Fig. 2 is a side elevation of the self-adapting sleeve roller partially expanded.

Fig. 3 is a side elevation of the sleeve roller completely expanded, parts being broken away and shown in section.

Fig. 4: is an enlarged cross sect-ion on the line l-l of Fig. 3 and looking in the direction indicated by the arrows.

Fig. 5 is a perspective showing the selfadapting sleeve roller collapsed and inserted into a coat sleeve.

Fig. 6 is a fragmentary perspective showing the self-adapting sleeve roller expanded and upon a steam presser.

Fig. 7 is an end elevation looking in the direction indicated by the arrow 7 in Fig. 1.

The details of construction and operation shown in the drawings are as follows:

The mating side bars 1 and 2 are formed of wood and are curved in side elevation to fit the curvature of a coat sleeve, and the outer edges 3 and 4 of the bars are round in cross section. Leaf springs 5 and 6 are secured at their inner ends against the inner face of the side bar 1 and the leaf springs 7 and 8 are secured against the inner face of the side bar 2. The inner face of the side bar 1 is concave and the inner face of the side bar 2 is convex. Each one of the springs 5, 6, 7 and 8 consists of a main leaf 9 and a secondary leaf 10. The inner ends of the leaves 9 and 10 are brought together and rivets 11 and 12 are inserted through the side bar and through the ends of the leaves. A clip 13 is secured transversely against the outer side of the free end of the leaf 10 by a rivet 1 1, and the ends of the clip are bent around the leaf 9 loosely so that the clip will slide freely upon the leaf 9 and so that the clip will connect the free end of the leaf 10 to the leaf 9. The springs are preferably made of heavy clock spring material. A hinge 15 connects the free ends of the springs 6 and 8 and a hinge 16 connects the free ends of the springs 5 and 7. The springs 7 and S are slightly longer between the hinges 15 and 16 than the springs 5 and 6 so that the springs 7 and 8 bend more than the springs 5 and 6 when the device is completely expanded as in Fig. 3, and so that the springs 5 and G lay flat against the inner face of the side bar 1 when the device is only partially expanded as in Fig. 2, and so that when the side bars 1 and- 2 are forcibly pressed together the springs 7 and 8 buckle slightly until the hinges 15 and 16 pass the plane of the center of the side bar 2, and continued compression will cause the side bars 1 and 2 to snap together and be held together in collapsed positions, as in Fig. 1.

When the collapsed sleeve roller shown in Fig. 1 is inserted in a coat sleeve 17 as shown in Fig. 5, the extending ends of the side bars 1 and 2 may be forced apart, and then the springs will expand the side bars 1 and 2 to fit the sleeve, as shown in Fig. (5. and then the expanded sleeve may be placed upon the press board 18 and the steam board 19 applies as usual to steam and shape the sleeve. The device may be left in the sleeve for any desired length 0t time and then removed.

The round outer edges 3 and e of the side bars 1 and 2 will produce a roll finish and will leave no creases, and this is especially desirable in the treatment of womens clothes and the like.

It is apparent that the principle 01 utilizing the springs substantially as shown may be embodied in other types oit. garment stretchers. An internal tranie could be made up as shown in the illustrations. and an external frame attached thereto to con form to theshape ot the trousers, woniens skirts or other articles it is desired to stretch. So long as the co-acting faces and the springs are substantially the same as illustrated and described, other outer training or shape to the bars could be utilized.

Various changes may be made without departing from the spirit of the invention claimed.

o claiin 1. A self-adapting sleeve stretcher comprising a pair of bars havingparallel longitudinal curved inner faces, leaf springs cured at their inner ends to the confronting faces of the bars, and hinges connecting the free ends of the springs of one free ends of the springs of the other bar. the tensions of the springs being exerted to press the bars apart after their separation a known distance and the retraction of the springs being adapted to draw the bars together after their compression to said dist ance.

2. A self adapting;- sleeve stretcher. comprising a pair of bars having parallel longitudinal curved inner faces, one bar having a concared confronting race and the other bar having: a convex face, leat springs secured at their inner ends to the confronting tacos ct the bars and hinges connecting the tree ends of the springs of one bar to the free ends ot' the springs of the other bar, the tensions ot the springs being exerted to press the bars apart after the bars are separated a known distance, and the springs of the convex eonfronting face being slightly longer than the springs of the concave confronting taco that the bars will snap together when pressed nearly to a known distance apart to hold the bars contracted.

In testimony whereof we have signed our names to this specification.
