CONNECTION FOR WEBBED BOTTOM. SEATS Filed July 25, 1930 Patented Nov. 22, 1932 SAMUEL S. BERNSTEIN, 015 BEVERLY HILLS, CALIFORNIA CONNECTION FOR WEBBED BOTTOM SEATS Application filed July 25,

This invention has to do in a general way with the manufacture of furniture, and is more particularly related to that type of furniture which includes a supporting memher of the type ordinarily known as webbed construction.

The webbed construction referred to above is usually employed in the backs or the bottoms of-chairs, or the like, and consists of a frame which contains a plurality of interlaced strips of webbing'or other similar flexible material. It has been the usual practice in attaching this webbing to the frame to secure the same thereon merely by nails or tacks. Due to the fact that the webbing, after a period of time, tends to stretch or sag, and also due to the fact that the initial strain placed upon the webbing and transmitted to the attaching means when a weight is placed thereon frequently pulls the nails from the frame or tears the webbing, it is a primary object of this invention to produce a device for'attaching webbing of the class described to the frame which is constructed so that it may be adjusted from time totime to tighten or loosen the webbing, correcting for any sagging or shrinking action, and which is also formed so that it is resilient 0r yieldable, and

. will absorb the initial strain placed upon the webbing, thus safeguarding against the webbing being torn.

In my prior Patent No. 1,774,696 which was filed April 28, 1928, and issued on Sept. 2, 1930, I show a connecting member of the general character described above, which consists of a stirrup adapted to be attached to the end of the webbing and provided with means for attaching same to the frame. This stirrup is attached to the frame by means of a bolt or screw and is held in yieldable relation therewith by means of an independent cushioning member, which may be in the form of a rubber cushion or compression spring. The device contemplated by the present invention may therefore be con- 1930. Serial No. 470,637.

sidered as an improvement upon the one disclosed in the application referred to above.

It becomes a further object of the present invention to produce a device of the class described wherein the stirrup is so constructed as to have an inherent resiliency, which eliminates one of the elements used in my former invention. This object is accomplished by making the attaching means in the form of a spring plate, which is provided with an aperture through which it is secured to the frame by an adjustable screw, and which has formed on opposite ends thereof side members to which the webbing is secured by a transverse bar.

Details in the construction of the preferred form of my invention, together with other objects attending its production, will be best. understood from the following description of the accompanying drawing, inwhich Fig. 1 is an inverted plan view, showing the frame of a chair seat which is equipped with webbed supporting structure, the elements of which are connected to the frame by means of my invention; 7

Fig. 2 is an enlarged sectional elevation of one of the side members shown in Fig. 1 and adjacent parts;

- Fig. 3 is an enlarged perspective view of the connecting stirrup contemplated by this invention; and

Figs. 4, 5 and 6 aresectional views showing various forms of adjusting means.

More particularly describing the invention as herein illustrated, reference numeral 11 indicates a chair frame embodying legs 12 and 13, side members 14, a front bar 15, and a rear bar 16. The chair set embodies a plurality of interlaced strips of webbing 17, which are shown as being tacked to the front bar 15, and attached to the side bars 14 and the rear bars 16 by connecting means indicated by reference numeral 18.

The webbing is shown as forming the support for a plurality of springs indicated by 00 necting member 18 are best illustrated in Figs. 2 and 3, where such member is shown as comprising a U-shaped stirrup which is preferably formed from a single strip of spring material, and may be described as embodying a curved end plate section 22 which has an aperture 23 formed in its center, such aperture being adapted to receive a screw member 24. The screw member 24 is shown as comprising a wood screw section 25, adapted to be inserted in the frame, and a machine screw section 26 which carries a wing nut 27 for imparting adjustment to the end plate 22.

It will be understood that while the particular type of screw connection shown has certain advantages, other forms may be used, for example I may employ an ordinary wood screw with asquared or slotted head or with an eye, effecting the adjustment by advancing same into the wood. Such forms are indicated in Figs. 4, 5 and 6 by reference numerals 23a, 23b, and 230. It will be noted that in these forms of my invention the side members 28a, 28b, and 280 may be made shorter than the member 28. The end plate 22 carries a pair of oppositely disposed side plates 27 and 28, to which the webbing 17 is attached through the medium of a transverse bar 29. The webbing may be secured to the bar in any well known manner, as by looping the same over the bar and either sewing or riveting the loop end to the body of the strip.

It will be apparent from the foregoing description that the device contemplated by this invention is of simple form and construction; it may be economically manufactured;

' and it can be easily and quickly installed and adjusted. The curved end plate section 22 is of a resilient nature so that it absorbs the initial strain received by the webbing when a weight is placed upon the chair seat, and

this construction has a further advantage in that it is impossible for the parts to get out of alinement, as is the case when the con- .nection consists of more than one member.

It is to be understood that while I have herein described and illustrated one preferred form of my invention, that the invention is not limited to the precise construction described above, but includes within its scope such changes as may fairly come within a plurality offlexible strips disposed across said frame; a resilient stirrup attached at its ends to each strip; and adjustable means verse member, and means at the midportion of said resilient member connecting said stirrup to said frame.

4. In an article of furniture which includes a frame having flexible strips disposed thereacross means for attaching said strips to said frame embodyin a resilient stirrup consisting of side mem ers, an end member and a transverse bar disposed between said side members, said end member being provided with a central aperture; and screw means extending through said aperture for adjustably securing said stirrup to said frame.

5. In an article of furniture which includes a frame havin flexible strips disposed thereacross means or attaching said strips to said frame embodying a resilient stirrup consisting of'side members, an end member and a transverse bar disposed between said side members, said end member being curved inwardly toward said transverse bar and provided with a central aperture; and screw means extending through said aperture for adjustably securing said stirrup to said frame. 7

6. In an article of furniture which includes a frame having flexible strips disposed across said frame: means for resiliently attaching said strips to said frame, said means comprising a resilient plate attached to the end of each strip; an means for attaching said plate at its central portion to said frame.

7 In an article of furniture which includes a frame having flexible strips disposed across said frame: means for attaching said strips to said frame comprising a bowed plate formed of resilient material and having an aperture formed substantially in the center thereof; threaded means mounted in said frame and extending through said aperture for adjustably securing said bowed plate to said frame; and means for connecting a flexible strip to said bowed plate comprising side plates projecting from said bowed plate and a transverse bar disposed between said side plates.

8. In an article of furniture, a seat. embodying: a frame; a plurality of flexible strips disposed across said frame; and means for resiliently connecting said strips .to said frame, said means includin a stirrup having a ,resilient transverse mem er, side members extending from said transverse member, means for connecting the side members to the strip, and a member secured to said frame eng 'ng the central portion of the transverse mem r of the stirrup. v

9. In an article of furniture, aseat'embodyin a frame; a plurality of flexible stri s isposed across said frame; means for res' 'ently connecting said strips to said frame, said means including end of each strip havin a resilient transverse member, side mem rs 'on said transverse member attached to the end of the strip and means attaching said transverse member at its midportion to said frame.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 9th day of July, 1930.
