SPRING STRUCTURE Original Filed Sept. 19; 1929 mvEhfroR [5/00/751 05/!6/7 Patentecl July 21 193i UNITED STATES PATENT QFFECE FALCONER OIBRIEN, OF DETROIT, MICHIGAN, ASSIGNOR TO L. A. YOUNG SPRING 8: WIRE CORPORATION, OF DETROIT, hiICI-IIGAN SPRING STRUCTURE Original application filed September 19, 1929, Serial No. 393,640. Divided and this application filed May 15,

1930. Serial This application is a division of my application for Letters Patent filed September 19, 1929, Serial No. 393,640.

The main object of this invention is to provide in a spring structure an improved brace whlch 18 effective in supporting or ment of my invention is illustrated in the accompanying drawings in which:

Fig. 1 is a fragmentary plan view of a spring cushion structure embodying the features of my invention.

Fig. 2 is a fragmentary section on line 2-2 of Fig. 1.

In the embodiment of my invention illustrated the body springs l are of the hourglass type, the outer springs being secured to the top border frame 2 by means of clips 3 and 4, the clips 4c being elongated to engage a pair of adjacent springs and also serve to connect the brace elements as will be hereafter described.

The bottom rim 5 illustrated is of the S type, the inner channel being clamped upon the bottom coils of the outer spring while the outer channel is adapted to receive the upholstery.

Certain of the springs are connected by tie or cross members 6 of channel cross section, these members being secured to the springs by clamping upon the intermediate coils thereof.

Opposite sides of the top border frame are tied together and braced by a cross brace consisting of brace members 7 which are connected to opposite sides of the border frame by means of clips 8, these members having laterally turned ends 9 engaged by the clips.

The members 7 have coupling engaging arms 10 at their inner ends disposed laterally and projecting in opposite directions, these arms being engaged in the coils of the coiled spring coupling member 11. The end coils of this couplin member are engagcd with the top coils of adjacent springs.

The members of the top frame are thus braced against lateral movement, at the same time its vertical movement or the vertical movement of the springs is not materially restricted by the brace.

I also employ in this structure jointed braces connected by coupling members 12 and 13, the coupling member 12 being secured to the member 6 while the coupling member 13 is secured to the clip l. This brace is the subject matter of claims in the original application.

I have illustrated and described my improvements in an embodiment which has been found to be very practical. I have not shown various embodiments and adaptations of which it is capable as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination in a spring structure of a plurality of coiled body springs, a border frame, a cross brace therefor comprising a pair of members connected to opposite sides of the border frame, and a coiled spring coupling member for said brace members, said brace members having laterally disposed coupling engaging members engaged within the coils of said coupling member, the coils of the ends of said coupling member being engaged with coils of adjacent body springs.

A spring structure comprising an as sembled set of body springs and a frame element, a brace connected to said frame element and disposed between adjacent body springs, and a coiled spring coupling member connected at its ends to a pair of the body springs, said brace having a laterally disposed portion engaged within the coils of the coupling member.

In witness whereof I have hereunto set my hand.

FALCONER OBRIEN.
