Patented May 6, 1913. Divided and.this application filed July 3,

1912. Serial No. 707,586.

To all whom it may concern! 1 Be it known that I, GEORGE B. BRINK, a citizen of the United States, residing at Plymouth, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in ,Spring Structures, of which the following is a speci' fication.

This invention relates to spring structures.

frame to which the spring su porting wires may be firmly connected an to which the cover facing may be readily secured.

Another object resides in the provision of a frame for spring stiuctures embodying such characteristics that the stay or supporting wires ma be readily secured firmly thereto without t e instrumentality of separate fastenings.

With the aboveand other objects in view 25 pointed outin the appended claim, it being understood thatchanges may be made in the form, pro ortion, size and minor details without eparting from the scope or sacrificing any of the advantages of the 0 invention.

In the drawings: Figure 1 is an inverted plan view of a spring structure illustrating my improved base frame. Fig. 2 is a transverse sectional view of a spring structure my invention and including the upholsterlng material and fastenings. Fig. 3 isan enlarged fra entary sectional view.

Fig. 4 is a view siml ar to Fig. 3 illustrating.

the side facing of the cover secured to the ig. 5 is a fragmentary sectional view of a modification. Fig. 6 is a fragmentary sectional view illustrating one means for connecting the binding element of the side facing to the base frame.

Referring now more particularly to the 'accompanyin drawings the'reference characters A an B indicate upper and lower frames respectively. The upper frame is preferably of wire while the lower frame is com osed preferably of sheet metal and of an e formation toprovide side portions 12 an base flange portions 13 with the side portions 12 preferably directed inwardly to provide an external longitudinal groove 14, and then directed outwardly to provide an inwardly One object is to provide a novel base' opening longitudinal groove immediate above the base flangeportion 13. The base flange portion- 13 of the lower frame B provi es for an ample base for the entire structure and as the flange portion 13 extends entirely around the lower frame it also provides a substantial rest for the ends of the supporting wires 15. The ends of the sup orting wires 15 are preferably curved as.

indicated at 16 in Fig. 1 and are secured to the'base flange portions 13 fixedly by turning in, as by a welding or other process, the edges of the base portions to form binding lips or parts 16.

Arranged between the upper and lower frames are springs 18, the lnner ones may be secured to the supporting wires in any suitable manner and the marginal ones of which on opposite sides of the structure may be secured to the sides of the u per and lower frames and to the correspon ing' supporting wires in any suitable manner, but preferably solely on the supporting wires and not on the frame.

It is customary to lace upholstering material 19 on the top 0? sprin structures and over this I dispose a top facing 20 which may be secured to the top of the structure in an suitable manner and the front, back and side facings 21 may besewed or otherwise secured to the top facing 20 at 26. There is preferably sewed in the outer or lower edges of theside facings a wire 22, which is preferably continuous with its ends preferably secured together by means of solder as indicated at 23 in Fig. 1. 'If preferred, there may be struck up from the marginal portion 12 of the lower base portion a tongue 24 (see Fig. 6) which may extend through the side facings 21 and over the edges of this tongue 24, the ends of the wire 22 may be bent as indicated at 2?) in Fig. 6. A cord, rope or'other equivalent element may be substituted for the wire 22 so long as it serves the function of providing for an efiicient or novel means for holding or drawing the side facings of the cushion at their outer or lower edges in the external longitudinal groove 14. of the base 1% frame.

If it be desired, a bottom facing 27 (see Fig. 5 may be employed to cover the bottom 0 the structure, and if it be used it is sim 1y necessary to place the edges thereof in t e groove-14 and by virtue of the hind ing or clamping action of the cable or'other securing means 22. between-which latter and. the bottom of the groove lel'the'bottom edges of the facing 27 are disposed, the bottom fag- 1% ing is held securely in place. The base frame of my strupture, therefore, provides not only a; base frame for spring structures but also provides means whereby the side facings of the finished article may be socured thereto asmay also be secured thereto a bottom facing, if used. It will thus be seen that I provide a base frame which is constructed for the ready ap plication thereto of the side facings of an upholstered cushion and that I also provide an eficient means for securing the spring supporting wires to the frame. .It will also be seen in the modifid'ation shown in Fig. 5

reemie be secured in said groove 14 of the base frame.

This application is a division of theapplication filed by me'on April 25, 1912 for spring structures, Serial No. 693,231.

What isclaimed is A baseframe for spring structures comprisin a member formed of angle iron with one 0 its portions directed inwardly and 'with its other portion provided with an internal longitudinal groove and also with an external longitudinal groove.
