PORTABLE CYLINDRICAL DRIER FOR FABRICS.

SPECIFICATION forming part of Letters Patent No. 487,600, dated December 6, 1892.

Application filed April 15, 1892.

To all whom it may concern.-

Be itknown that I, ALBERT BOROHARD'I, of Brooklyn,New York, have invented a certain Improvement in Portable Cylindrical Driers for Curtains and Fabrics of Delicate Texture, of which the following is a specification.

The object of this invention is to facilitate the drying of curtains and fabrics of delicate texture, which require to be symmetrically stretched in order to retain their shape in drying.

The invention consists of a hollow cylinder of muslin or other suitable fabric having its end portions circumferentially inclosing and fastened to two light wheels loosely mounted upon a shaft provided with adjustable means for holding apart said wheels, and thereby 'stretchingsaid muslin cylinder longitudinally.

The muslin cylinder is preferably marked with parallel circumferential lines to serve as guides to facilitate the symmetrical adjustment and fastening to the cylinder of the objects to be dried.

The accompanying drawings, illustrating the invention, are as follows:

Figure 1 is an end elevation. 7 side elevation,partly in section. Fig. 3 is an isometrical perspective of the collapsed cylinder. Fig. 4, is an elevation of the shaft detached. Fig. 5 is a longitudinal sectional view of a portion of the cylinder, showing one of the hoops in transverse section and showing the outerportion of one of the spokes.

The portable drying-cylinder illustrated in the drawings is composed of the tube or cylinder a, of muslin or other suitable fabric, the end portions 0. and a of which are respectively turned inward and fastened to the outer edges of the hoops b and cin any convenient manner-as, for examplaby means of a series of tacks d, driven through the overlying tapes I) and 0 into the hoops. The hoop b is provided with spokes, preferably consisting of two crossed strips of wood e and f, having their ends fastened to the inner edges of the hoops, and the hoop c is similarly provided with spokes consisting of the crossed strips of wood e and f. At the places where the strips cross they are provided, respectively, with the perforations e and f for admitting the shaft g, which constitutes the axis of the Fig. 2 1s a Serial No. 429,316. (No model.)

cylinder. The shaft 9 is provided with several transverse perforations h to receive the pins h and 71. by means of which the hoops are held at such distance apart as will properly stretch the muslin cylinder a.

The muslin cylinder is provided with the system 1: of parallel circumferential marks, which serve as guides to indicate the appropriate position upon the cylinder for the object to be dried. For example, the marks facilitate the pinning to the cylinder of a currain with its edges parallel to eachother, whereby the conditions of parallelism will be maintained during the drying of the curtain. It will of course be perceived that the cylinder may be of any desired dimensions. For drying curtains a cylinder, say, of four feet in diameter and five feet in length will usually be suitable.

The entire structure is Very light and when required for use may be supported by resting the projecting ends g g of the shaft upon the backs of two suitably-placed chairs or other objects. turned step by step by hand as the curtain or other object to be dried is being pinned to its perimeter. When desired,the transverse pins h k can be withdrawn, and the shaft g, being removed, the hoops b and 0 can be pressed together and the cylinder collapsed, as illustrated in Fig. 3. In this collapsed condition the structure occupies very little space and can be readily stored away until again required for use.

Each of the hoops, with their cross-pieces, constitutes alight wheel of simple construction. The flat cross-strips which serve as spokes are adapted to spring in the direction of the axis of the cylinder, and hence impose an elastic stretching strain upon the muslin perimeter of the cylinder when the wheels are forced apart by the insertion of the pins h it through the appropriate transverse holes h on the shaft g.

Ample room is afforded by the spaces between the spokes for access to the interior of the cylinder for the purpose of appropriately inserting the pins. It will therefore be seen that the shaft g, transversely perforated, as shown, and provided with the removable pins h h*, constitutes a stretcher for more or less In this position the cylinder can be tightly stretching the muslinperimeter of the cylinder in the direction of the axis thereof.

What is claimed as the invention is- 1. In a portable drying-cylinder, the combination of two light wheels and a hollow cylinder of muslin having its end portions circumferentially inclosing and fastened to said wheels, respectively, with a stretcher for bold ing said wheels apart, and thereby stretching said muslin cylinder longitudinally.

2. A hollow cylinder-of muslin with itsend portions circumferentially fastened to the perimeter of two light wheelsloosely mounted upon a central shaft provided with removable transverse pins for holding said wheels apart.

3. A hollow cylinder of muslin with its end portions circumferentially fastened ,toithet perimeter of two light wheels provided with spokes adapted to spring in thedirection of.

E holding said hoops at: prescribed distances the axis of said cylinder, in combination; with a central shaftyprovided-with adjustable means for v holding said wheelseapart, and

thereby imposing anelastic outward strain upon theopposite ends, respectively, of said, muslin cylinder.

4:. The combination, as herein set forth, of the muslincylinder a, the hoop 1b, the crosspieces 6 and f, the hoop c, the cross-pieces e and f, the shaft 9, of greater length than the cylinder a, and the transverse pins h and b 5. A tube of muslin, two hoops inserted within the-opposite ends-thereof, respectively, and fastened to the muslin by having tacked to their outer edges the inwardly-turned end portions of said tube,ain combination with two systems of crossed slats'having their ends fastened, respectively, to the inner edges of the hoops, a central shaft. inserted through perforations in' the crossed portions of said slats; suitably-located transverse holes in said shaft, and two pins adapted for insertion in said transverseholestor thepurposeof bearing, respectively upon- ;the;inncr surfaces of said systems-.oftcrossed slats and thereby aparh- ALBERT .BOROI-IARDT.v Witnesses:
