Application flied July 12,

T (1 11710111 it may concern Be it known that I. JAMES C. BRIAN, a citizen of the I nited States. residing at Minneapolis. in the county of Hennepin and State of Minnesota. have invented, certain non and useful Improvements in Cushions. of which the following is a speciiication.

This invention relates. to seats or cushions and the main object is to provide a self ventilating. eilicient and practical cushion or spring pillow which is porous so that air may readily circulate through it, and which is provided with a top covering of a fun mesh rust ploof screen. so that it will not only yieldingl and comfortably support the body. but will also prevent ex:- i-essive heating and 'icispiration. \Vlllkll is so commonly experienced in hot weather with nod. leather. or fabric upholstered furniture and car seats. Further and more Specific objects will be disclosed in the course of the following specification, reference being had to the accompanying drawing. in which- Fig. 1 is a, plan view of the cushion, fractional portions being broken away to illustrate the interior construction.

Fig. 2 is a sectional elevation as seen on the line 2-2 in Fig. 1.

Fig. 3 is an enlarged perspective detail showing the frame construction.

Fig. 4 is a fractional detail sectional view of a spring fastener used in the device.

Referring to the drawing more particularly and by reference characters 4 designates an endless frame. of heavy sheet metal, having an inwardly flaring flange 5 at its lower edge. and having an outwardly bent or curved loop 6 at its upper edge. The frame 4 mav be round. oval. elliptical or of any other desired or suitable form and its shape is retained not only by the strengthening members 5 and 6, but also by a series of heavy wires 7, which have their ends hooked, as at 8, into spaced perforations about and in the flange 5. Secured upon the wires 7. by suitable means 9. is a series of spiral springs 10, having their larger ends up so as to cover as large a top or rest area as possible. Over the tops of the springs 10 is a series of zig-zag springs 12, which are suitably connected together as by clips 13 so as to form a yieldingly flat mat over the springs 10. The connected loops of the springs 12 are slightly 1924 Serial No. 725.578.

bent down. as shown in Fig. 4, so that the clip 13 will not project above the springs and into the screen. Stretched over the mat 12 is a cover member 14 which is preferably made of tine mesh rust-proof screen, which, it will be noted, has a diagonal weave f the wire to aiiect a diamond shaped mesh in the screen. This feature is considered very important, as a part of the invention, in that it permits the seat cover to expose a larger area of supporting surface. In fact by this method the wire can he so closely woven that the screen affects practically a solid surface. the openings only being large enough to permit the desired ventilation. while in a right angled weave, for instance, fewer wires can be used per square inch due to the abrupter curves in the weaving. and thus a weaker and less eflicient cover results than with the diagonal weave. This screen 14 is secured in place by a curved band 15 which is clamped against the frame 4 by suitable means such as bolts 16. The screen 14 is first pulled and bent down over the loo 6, it is then folded under a heavy wire I? (Fig. 3), and back against itself, in such a manner that when the band 15 is tightened against the frame 4 it will clamp the screen and tend to pinch the wire 17 downward. It will thus be seen that any strain on the surface or top of the screen cannot loosen it from the frame. but will rather tend to clamp it tighter by pulling or wedging the wire 1'? up into the wedge shaped restricted space between the members 4 and 15. If the cushion is to be used as a detachable seat for chairs or on other smooth or polished surfaces it may be provided with a rubber. fabric or composition rim 18 to prevent the metal parts from injuring such surfaces.

It is understood that suitable modifications may be made in the shape, general design and structural details of the spring cushion as herein shown and described, provided, however, that such modifications come within the spirit and scope of the appended claims.

Having now therefore fully shown and described my invention, what I claim to be new and desire to protect by United States Letters Patent is:

1. The combination in a spring cushion, of a circumscribing frame having an outwardly curved loop portion at its upper edge, springs within the frame, a motel screen cover over said springs and stretched over said 100p portien, a wire member com tained within a ford in said screen near the ed e thereof, an eutwardly tiered band secure about the frame to secure the screen thereto, said band being arranged to engage and clamp the screen between said loop and Wire.

2. In a cushion, a frame having an inturned flange at its -tower edge and formed with a bead at its upper edge, supporting members secured to said flange, springs arranged on said members, a perforated cover member covering said springs and stretched over said bead, and means including an outer band for securing the edge portion of the cover member to the outer periphery of the frame.

a meme 3. In a cushion, a eireumscribing frame having an inturned flange at its iower edge and formed with a bead at its upper edge supporting members secured to said flange springs arranged on said member a per forated cover member covering sair. springs and stretched over said bead, means in cluding an outer band for securing the edge portion of the cover member to the outer periphery of the frame, flexible zig-zag members, lying in the same plane, and in* terposed between said springs and cover member, and means for eonnerting together adjacent loops of different of said zig-zag members.

In testimony whereof I aflix my s1gnature.

JAMES C. BRIAN.
