Application filed lFebruary 15, 1912. Serial No. 677,780.
To all whom t may concern:
Be it known that I, SOLOMON M. RAFTERY,
This invention relates to back spring con-` struction of simple design adapted to aiford a yielding cushion edge for supporting upholstery without the application of edge rolls or the like.
The invent-ion consists in the matters hereinafter set forth and more particularlyy pointed out in the appended claims.
In the drawings, Figure l is a view in front elevation of a back spring embodying the invention; Fig. 2 is a View in end elevation thereof; and Fig. 3 is a diagrammatic y View showing approximately the position assumed ,by the members of the construction plurality of marginal body springs 2 of hour-glass or cylindrical type, the base coils of the springs being secured by suitable clips 3 to the frames-` Inner body springs d of greater height than the marginal springs 2 are supported by attachment of their base coils to the frame and to parallel cross stay rods 6 attached near .their ends by clips 7 or the like vto the base coils of the marginal springs. Stay strips 8 of suitable material connect the upper turns 9 of the marginal springs tothe adjacent body coils 10 of the inner springs. The upper coils 9 of the marginal springs are further interconnected by a suitably disposed continuous member l1 'secured as by clips 12 to the inner portions from thi` spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.
IfVhat I claim as my invention is 1. A. back spring construction comprising av frame, body springs secured around the margins thereof, inner body springs of greater height than the marginal springs and means secured to the middle coils of the inner body springs and tothe adjacentportions of the top coils ofthe marginal springs, the outer portions of the top coils being free to turn downwardly.
2.- A back spring construction comprising a rim frame, a plurality of marginal body springs whose base coils are secured thereto, stayrods secured in spaced relation across the frame to the base coils of the marginal body springs, inner body springs supported on the frame and stay' rods andprovided with upper, coils ext-ending beyond the plane of the top coils ofV the marginal springs and means articulating the intermediate turns of the inner body springs to the top coils of the marginal body springs, the top coils of the latter being free to tilt and the projectingportions of the inner body springs being free to tilt in any direction.
3. A back spring construction comprising a rim frame, a plurality of marginal body springs with their base coils secured to the frame, transverse members of the frame secured to the base co-ils of `the marginal springs, inner body springs of greater height than the marginal springs supported on the rim frame and transverse members, a single member connecting the inner\portions of the top coils of the marginal body springs and means articulating the single member to the adjacent intermediate turns. of the inner body springs, the outer portions of the body springs being free to tilt.
In testimony whereof I a'tlix my signature in presence of two witnesses.
