CUSHION CONSTRUCTION.

Application led Kay 14,

This invention relates particularly to elishions adapted for automobile purposes, for sleeping car purposes, or the like.

The primary object is to provide an improved cushion of staunch construction which possesses important advantages from the standpoint of comfort and from the standpoint of durability.

The present invention constitutes a modification of the invention described in my pending application `Serial No. 109,078, filed of even date. herewith.

The invention is illustrated in its pre-- ferred embodiment in the accompanying drawing, in which- Fig. 1 represents a broken plan view of the improved cushion; Fig. 2, a broken sectional view takenl as indicated at line 2 of Fig. l; and Fig. 3,` a broken inner face view of the cushion-bottom.

InA the embodiment illustrated, the cushion comprises a rectangular base-frame A which supports a bottom A; a marginal row of upholstery springs B supported on the frame A and connected at their upper ends with a marginal rod B; an inner body of upholstery springs C supported on the bottom A', the upper ends/of the marginal row of the inner or main body of springs being connected with a marginal rod C; a filling of suitable stuiiing, or Wadding, material D, such as hair, moss or cotton, disposed above the springs; and a covering E which may comprise a ply of burlap 1 and a inishfabric 2.

'lhe outer marginal row of springs B preferably are enclosed in individual pockets, or coverings, of fabric 3; and the springs are united at their upper ends by ties,or stitches, 3a. The springs B are also connected with the marginal rod B as by means ot ties, or stitches, 3".

The springs C of the main body of springs preferably are encased in individual fabric containers 4. These springs are longer than the springs of the outer marginal Arow B, and preferably are somewhat lighter. The springs C are connected at then' upper ends by ties, or stitches, 4a; and the springs of the marginal row of the main body of springs are connected vwith the marginal rod C ,by ties, or stitches, 4".

The base ofthe structure comprises the rectangular fra-me A and the b ottom A which may be regarded as a portion o f the 1926. Serial N0. 109,079.

supporting frame, or base, of the structure. Thebottom A preferably is composed ot' sheet-metal. The sheet-metal member has an upturned lla-nge 5 which fits within the frame A and is equipped with supporting lugs 5a which are bent over the upper surface of the frame A and secured thereto, as by means of nails 5b.

If desired, the bottom A may be provided with perforations 6 equipped with inwardly opening valves 62L (one shown). These valves may be of leather secured at one point to the bottom A', as by means of a rivet 6b. The valves open inwardly or upwardly to admit air when the cushion is distended; and they close to give a pneumatic cushionlng etl'ect when the cushion is compressed.

As will be noted from Fig. 2, the main body of springs C have their upper endsprojecting some distance above the outer marginal row of springs B; also, by reason of the fact that the bottom A is depressed so as to be substantially flush with the lower surface of the frame A, the lower ends of the main body of springs extend below the lower ends of the outer marginal row of springs B.

'ljhe marginal row of the main body of springs C, or any desired number thereof, are connected by ties 7 with the upper end portions of the springs of the outer marginal iow B.

vThe covering E is stretched tautly over the springs and wedding l), and the skirt portions 8 of the fabrics are carried downwardly and secured to the frame A as by vmeans of tacks 9. Thus, the skirt portions of the covering furnish the usual flexible peripheral wall of the ciishoii.

lVhile the outer marginal row of springs B is anchored to the marginal row ot the main body of springs, there is a certain independent action of the main body of springs when the cushion is occupied. 'lliis is due partly to the. greater length of the main ody of springs, partly to the manner in which they are connected with the outer marginal row of springs, and partly to the fact that the outer marginal row of springs preferably are heavier, or stronger, than the main body of s rings. Otherwise stated, the main body o springs will yield readily and conform to the person, while the outer row of springs will offer more resistance and tend to give a certain desired firmness of support t0 the limbs vnear thel knees. This uo f action will occur without inconvenience to the erson seated on the cushion, owing to the act that the marginal row of the inner main bod of will yieldv rather readily when the person is seated. Moreover, the

outer marginal row of springs tends to pre- The improved cushion is a self-sustaining structure which may be placed upon any suitable support. The improved cushion may be made of necessary length and of the right proportions to serve as a seat cushion or as a back cushion in a sleeping car berth, where the advantages noted are highly desirable.

What I regard as new, and desire to secure by Letters Patent, is:

1. A cushion comprising a base, an outer marginal row of upholstery springs mounted on said base, fabric coverings enclosing the individual springs of said row, an inner main body of upholstery springs mounted on said base and rising a substantial distance above said outer marginal row of springs, individual fabric coverings en closing the individual springs of said main body of springs, a marginal rod secured to thel upper 'end portions. of the outer marginal row of springs, a marginal rod secured to the upper end portions of the marginal row of the main body of springs, ties connecting the upper portions of the outer marginal row of springs and the adjacent intermediate rtions of the marginal row of the main y of springs, stuing material above said groups of springs, and a fabric covering enclosing the stuiling material and springs and secured to said base.

2. A cushion vcomprising a base, an inner `main body of relatively light upholstery springs encased in individual fabric coverings, said springs beingnested in close contact with each other and connected b an outer marginal row of relatively stiff upholstery springs encased in individual fabric casings contacting with each other and connected by ties, said last-named springs having their upper ends disposed a substantial distance below the plane of the upper ends ties,

of the main body of springs, a marginal rod connected with the upper ends of the marginal springs of said main body of springs, a marginal rod connected with the upper ends of said outer row of springs, ties connectinjg the upper ends of the outer marginal row o springs with the adjacent intermediate portions ofthe marginal springs of the main body Aof springs, stuiling material above the groups of springs mentioned, and a fabric covering enclosing the stufling material and springs and secured to said base.

3. A cushion comprising abase consisting of a marginal frame-member and a relatively thin bottom secured to said framemember so as to be substantially flush with the lower surface of said frame-member, an` louter marginal vrow of upholstery springs mounted on said base, fabric coverings enper portions of the outer marginal row of a springs and the adjacent intermediate portions of the marginal row of the main body of springs, stuffing material above said groups of springs, and a fabric covering enclosing the stuiling material and springs and secured to said base.
