Application June 2'7, 1945, Serial No. 601,734

3 Claims.

This invention relates, in general, to clothes racks of the rotary type and constitutes an improvement over the rack disclosed in the Pollard et a1. Patent No, 2,289,450 of July 14, 1942.

The object of this invention is the provision of a radially collapsible rotary clothes drier, the metal fittings of which can all be made of die stampings and readily assemblied to produc an operating mechanism.

The invention possesses other advantageous features, some of which with the foregoing will be set forth at length in the following description where one form of the invention has been selected for illustration in the drawing accompanying and forming a part of the present specification is outlined in full. in said drawing, one form of the invention is shown, but it is to be understood that it is not limited to such form, since the invention as set forth in the claims may be embodied in other forms:

Referring to the drawing:

Fig. 1 is a front elevation of a vertically collapsible rotary clothes drier embodying the objects of my invention.

Fig. 2 is a partial central vertical section showing the drier illustrated in Fig. 1 in its collapsed position.

Fig. 3 is a fragmentary central vertical section showing the clothes rack in its open operative position.

Fig. 4 is a detailed vertical section of the upper end of the rack standard and its associated mechanism.

Fig. 5 is an enlarged elevation of the upper end of the rack standard an its associated parts.

Fig. 6 is a horizontal section taken on the section line 6-6 of Fig. 5.

Fig. 7 is an enlarged section taken on the line ll of Fig. 3.

Fig. 8 is a front elevation of the structure shown in Fig. 7,

As shown in these figures, the objects of my invention have been embodied in a rotary clothes drier rack comprising a block I in which is detachably mounted a post or standard 2 of circular cross section. Disposed over the upper end of the standard 2 is a cylindrical upper collar 3 provided with an inwardly extendin circular flange 4 arranged to seat on the upper end of the standard. Inserted into the upper end of the standard 2 is a screw 5 provided with a square or hexagonal head as, this head having positive clearance with the upper collar 3 so as to permit the rotation of the collar with respect to the standard 2. Seated on the head 6 is a washer. I and securing the washer in place is a wing nut 8. The upper collar 3 is provided with two pairs of diagonally disposed, longitudinally extending, symmetrically arranged slots B as best indicated in Fig. 6. Threaded through each pair of slots 8 is an outwardly extending U- shaped upper hinge member 9. Pivoted to each of these four upper hinge members 9 by a bolt [0 is a connecting arm ll of channel form.

Secured to two opposed pairs of adjacent hinge members 9 by the bolts I0 is an outwardly facing, U-shaped stiiiening member l2. Welded to one or more of these stiffening members is a downwardly extending, outwardly bowed, spring finger l3.

Rotatably and slidably mounted on the standard 2 below the upper collar 3 is a lower collar I4, and welded thereon are two diametrically opposed outwardly extending symmetrically arranged hinge members l5. Pivoted to each of the hinge members l5 by a bolt I5 is a clothes line rack arm ll, preferably made of wood.

Snugly fitting around each of the rack arms I 7 intermediate its ends is a pair of opposed U- shaped caps 18. Pivoted to each of the rack arms I! through its associated pair of opposed caps if! by means of a bolt I9, is the outer end of one of the connecting arms H. Secured to and between each pairof adjacent lower hinge members It by means of the bolts i6, is an outwardly facing stiffening angle 2 l.

Formed on the lower end of each of the downwardly extending spring fingers E3 is an outwardly and upwardly extending hook 22, arranged in the operative position of the rack to engage the lower edge of the adjacent stiffening member 2| (see in Fig. 5). Each of the rack arms I! is formed with a plurality of perforations 23 and threaded through these perforations is a clothes line 24. From an inspection of this figure, it is to be noted that the lower ends of the spring fingers l 3 pass between the outer face of the lower collar l4 and the inner face of the stiffening angles 2!. To collapse the rack above described, it is necessary only to raise slightly the lower collar M so that the stiffening angles 2i will clear the upper edge of the hook members 22 and then to spring the lower ends of the spring fingers l3 inwardly and simultaneously to permit the collar M to drop under the influence of its own weight and the vertical component of the weight of the rack arm assembly. To open the rack to its operative position, it is necessary simply to raise the rack until the stiffening angles 2| have reached a point above the hooks 22, whereupon the spring fingers will move outwardly under their own resiliency so as to permit the hooks 2| to engage the lower edges of the stiffening members when the lower collar 14 is permitted to drop.

From the above description it should be noted that I have described the rotary clothes rack assembly, all of the metal fittings of which can be economically made by die stamping and which can be simply and rapidly assembled.

I claim:

1. A clothes drier comprising: a standard; a first collar provided with an inwardly extending flange rotatably mounted on the upper end of said standard, said collar being provided with diametrically opposed pairs of circumferentially spaced longitudinally extending slots; an outwardly extending U-shaped hinge member threaded through each of said pairs of slots; a connecting arm hinged at its inner end to each of said U-shaped hinge members; a second collar mounted on said standard below said first collar; diametrically opposed rack arms hinged at their inner ends to said second collar and pivoted intermediate their ends to the outer ends of said connecting arms; a spring finger mounted on one of said collars and arranged to extend longitudinally in the direction of said other collar; and means for detachably securing said spring finger to said other collar.

2. A rotary clothes drier comprising: a standard; a first collar provided at its upper end with an inwardly extendin flange rotatably mounted on the upper end of said standard, said collar being provided with two pairs of diametrically opposed peripherally spaced and longitudinally extending slots; an outwardly extending U- shaped hinge member threaded through each pair of said diametrically opposed slots; a connecting arm hinged-atits inner end to each of said hinge members; a second collar slidably and rotatably mounted on said standard below said first collar;

diametrically opposed outwardly extending U- shaped hinge members secured to said second collar; a rack arm hinged at its inner end to each of said second outwardly extending U- shaped hinge members and pivoted intermediate its ends to one of said connecting arms; a downwardly extending spring finger mounted on said upper collar; and means for detachably securing the lower end of said spring finger to said second collar.

3. A rotary clothes drier comprising: a standard; a first collar rotatably mounted on the upper end of said standard; two pairs of diametrically opposed outwardly extending and symmetrically arranged U-shaped upper hinge members mounted on said first collar; an outwardly extending U-shaped stiffening member secured to and between each adjacent pair of U-shaped hinge members; a second collar slidably and rotatably mounted on said standard below said first collar; two pairs of diametrically opposed outwardly extending U-shaped lower hinge members secured to said second collar, one in vertical alignment with each of said upper hinge members; outwardly extending U-shaped lower stiffening members secured to and between each pair of said lower U-shaped hinge members; a downwardly extending spring finger fastened to each of said upper stiffening members and arranged to have its'lower end pass between said lower collar and one of said lower stiffening members, each of said spring fingers being provided at its lower end with an outwardly extending lug arranged to catch on the lower edge of its associated lower stiffening member; a rack arm pivoted at its inner end to each of said lower hinge members; and a connecting arm hinged at its inner end to each of said upper U-shaped hinge members and at its outer ends to one of said rack arms intermediate the ends thereof.
