Upon the rotation of the revoluble member 0 by the crank b the fabric is drawn tight against the tension of the springcoils b of the respective inverted-U members I) I). he tension or height of the pillow is readily adjusted by giving to the revoluble member I) a greater or less number of revolutions which causes the fabric strip 0 to be wrapped about said No. 830,837.

to provide a construction anc which w ll permit the free The drawing represents a perspective view of the device, similar parts of which are indicated by corresponding characters of reference.

Referring by letter to the drawing, a a represent two parallel tubes connected at opposite ends by transverse tie-wires a a, which extend into the tube and are brazed or soldered, thus forming a rectangular frame or base. There are also projected into the ends of the tubes and secured therein by brazing or soldering the ends of two inverted-U- shaped members I) b. Each of the invertedis formed of resilient or springwlre, and ad acent to the ends of the respective tubes a a each is formed with spring-coils 6 The tendency of the inverted-U-shaped members I) b spring-coils b is to straighten into a plane coincident with that of the rectangular frame formed by tubes at a and transverse wires (1 a.

In the respective legs of the inverted- U-shaped member I), at directly opposite points, are formed bights 6 which constitute the bearings for the revoluble member 6 The revoluble member 6 against further rotation by 7 of the extremity b of the crank I) with the leg of the inverted-U-shaped member Z). The various parts being of resilient material will spring aside sufficiently to allow the crank I) to pass while the strip is being wound upon the revoluble member 6 It is obvious that by the use of the same construction, but differently proportioned, being constructed on a largerscale of proportionately stronger parts, the devlce may be Havmg thus described my invention, I claim 1. As an article of manufacture, a device verted-U-shaped members attached to said rectangular frame, having a tendency to move into the plane of said rectangular frame,

earings formed on one of said inverted-U- shaped members, a revoluble member having member, means for securing said member in its adjusted position and a strip of fabric connected to one of said U-shaped members and extending over the other of said members and engaging with said revoluble member, substantially as specified.

2. As an article of manufacture, a device comprising two parallel tubes, transverse 1s provided with a longitudinal slot 6 for the purpose hereinafter mentioned.

In the drawing the revoluble member I) is shown as constructed of two parallel wires, one of which is extended, as at Z), to form a crank, the extremity of which is turned inward in a hook, as at b, to engage the leg of comprising a rectangular frame, resilient inwires connecting said tubes, and forming a rectangular frame, inverted-U-shaped members, formed of resilient wire, spring-coils formed in said U-shaped members, said mem- 5 bers being connected to the opposite ends of the respective aforementioned tubes, bights formed in one of said U-shaped members at directly opposite points on the legs of said member, a revoluble member for-med of two 10 parallel wires, sa1d wires being coherent at points adjacent to their extremities mounted in said bights, the projecting end of one of said parallel wires being formed; into a crank and adapted to engage with the legof said U- shaped member above or below said bight, 15 substantially as specified.

In testimony whereof I have hereunto set my hand this 27th day of February, A. D. 1906.
