CHAIR Filed March 15, 1930 2 Sheets-Sheet 2 r MM" I .2314, fle/zrl 9 2mm A itorney Patented Nov. 1, 1932 UNITED STATES ERNEST A. OEI-IRL, 0F GRAND RAPIDS, MICHIGAN I CHAIR Application filed March 15, 1930. Serial No. 436,200.

This invention relates to certain structural im rovements and advantageous commercial re nements in the construction of upholstered furniture in general.

More explicitly stated, the invention herein shown is embodied in an upholstered chair including an inclined cushioned back and a solid laminated seat of the tight covered ipecie and a novel spring suspension assem- The principal feature of novelty is predicated upon a solid laminated seat which is inlaid in a manner to telescopically nest itself into an upstanding marginal bead formed on the frame of the chair.

The specific details and their relative association and arrangement will become more readily apparent from the following descrip tion and drawings.

In the drawings:

Figure 1 is a view partly in section and part1 in elevation showing the general assemb y of details embodied in the construction of the seat.

Figure 2 is a top plan view showing the multiple coil spring assembly.

Figure 3 is a fragmentary view thereof.

The essential details of the invention may well be seen in Figure 1. In this figure the numeral 4 designates the wooden frame and the numeral 5 indicates the supporting legs. The upstanding inclined back 6 is fashioned to provide a cushioned back rest 7. In accordance with the present invention I provide a series of coiled cushioning springs, as shown in the drawings, arranged in distin guishable rows of springs with four springs in each row. For instance, as seen in Figure 1, the front spring is indicated by the numeral 8, the second spring 9, third spring 10, and the back or fourth spring at 11.

The lower coils or convolutions of each spring are stitched or otherwise fastened to the bottom webbing. This webbing is generally in the form of a heavy burlap. The coil springs are interconnected through the medium of twine of a suitable strength which is properly laced and connected with the convolutions of the spring to prevent lateral buckling and to tension the springs and to maintain them in an appropriate even or uniform plane with respect to each other.

The numeral 13 designates generally central horizontally disposed lengths of twine which constitute a central tie between the intermediate convolutions of the various springs 8 to 11 inclusive. The twine is an chored to the rear bar of the frame as indicated at the point lt and then tied to the corresponding convolutions of the springs 11, 10, 9 and 8 respectively, and the forward end of the twine is fastened on the front bar 4;

The purpose of this twine is to prevent lateral buckling, at the central portion of the springs. There is a second tie 15 which-extends from the anchor point 14 and this is connected with the third convolution as at 16 with the spring 11 and extending upwardly as at 17 and then across the tops of the springs in a manner represented. w

There is a tie 18 between the second coil of the spring 9 and the fourth coil of the spring 8. There is a similar inclined tie at 19 which extends from the frame upwardly through the coils to the front spring 8 and is attached to the uppermost coil of the same spring. I

This arrangement is for throwing the upper end portion of the spring 8 upwardly and forwardly to overlie the frame 4. This 0 lateral offsetting of the front coiled springs 8 in the complete assemblage is to provide a desirable spring edge for the seat. It may be added however, that the manner of lacing the twine may vary in chair constructions according to the estimated tensile strength of the respective coil springs. 7

In the particular arrangement herein shown comparatively heavy springs amused and the springs are such as to project a considerable distance above the frame to provide the desired yieldable result for a solid seat' structure. V

I invite attention at this time to one important factor of the improved arrangement and that is the upstanding substantially V- shaped marginal bead generally represented by the numeral 20. Thisbead extends along the opposite side portions' of the frame.

across the front, but of course is not disposed across the back.

It defines a marginal riser which is built up from a suitable filler 21 of hair or the like and this is covered with the finish material generally indicated at 22. The apex portion thereof is stitched through with thread to bind the filling sufficiently tight to present rather rigid bead. This bead cooperates with the solid cushion 23 in providing the desired inlay action. In other words, the cushion has its edge portion overhanding and cooperating with the upstanding V-shaped head to nest therein when weight is placed on the seat.

The seat itself extends from the rear part of the frame forwardly and has a curvate marginal edge portion 24 whose crown or crcstoverlies the apex portion of the V-shaped upstanding rim-like bead 20. Then the lower edge portion of the seat recedes inwardly to dispose it in spaced relation to the inwardly inclined inner surface of the bead.

This arrangement provides the desired telescoping or accordion-like action. The fact is that three marginal edge portions of the seat will nest nicely into this V-shaped rim forming bead.

The seat embodies a burlap covering 26' resting on the upper ends of the spring. Placed on this burlap is a layer of the best black hair 27 and then at 28 is a layer of thin burlap ply which may, if desired, be tufted.

At 29there is a layer of white hair stufling which is placed on the burlap partition piece 28. Then there is a layer of cotton stulfing as at 30 over which the muslin covering 31 is disposed. The final material 32 is in the finish which may be mohair, tapestry, cretonne and the like.

The gist of the invention is in the provision of a solid seattight covered spring cushioned structure, and the V-shaped upstanding riser forming a rimaround the frame of the chair and inlaid in a manner to telescope into the abounding head. There is also an advantage embodied in the spring edge construction wherein the upper ends of the marginal coil springs are properly drawn into the corner of the covering material as shown in Figure 1.

It is thought however that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the same after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size, and rearrangement of details coming within the field of invention claimed may resorted to in actual practice if desired.

Having thus described my invention, what I claim as new is:

In an article of upholstered furniture, a seat frame including front and rear pieces and side pieces, a cushioned bead secured to the upper face of the front and side pieces having its inner face inclined inwardly and downwardly, front, rear, and intermediate rows of coil springs, means connecting the springs together, means connecting the lower convolutions of the springs to the seat bottom, means anchoring the upper convolutions of the rear row of springs to the rear piece to limit the upward thrust thereof, a seat pad resting on the upper convolutions of the springs and having its rear edge contacting with the upper face of the rear piece, the sides and front of the pad inclining inwardly and downwardly and being free from the seat bottom, the inclination of the free sides and front of the pad corresponding to the inclined inner face of the cushioned bead to permit the telescoping of the pad within said seat bottom during the rising and falling of said pad.

In testimony whereof I affix my signature.

ERNEST A. OEHRL.
