T 0 all whom it may coneem:

Be it known that I, LEONARD A. YoUNG, a citizen of the United States of America, residing at Detroit,-in the county of Wayne" and State of Michigan, have invented cer -Q tain new and useful Improvements in- Spring Constructions, ;of which the following is a specification, reference being bad, therein to the accompanying drawin i In spring seat constructions-it is gsirable to reduce the number :of, parts and ,to simplify the means of connecting them in order not only. to cut down the cost of material but likewise that of the labor of This invention relatestospringconstruc tions in which spring members are secured to confining and supporting frames without the use of clips or other fastening means and without the necessity of previously slotting, perforating or otherwise tooling the mem-' bers of the frames; The invention consists in the-matters hereinafter set forth, and more particularl pointed out in the appended claims. 1

In the drawings, Figure Lisa view of a portion of .an upper rim frame with adjacent parts of springs, einbodying'the invention: Fig. 2 is a view in detail of a base frame showing methodof attaching springs thereto; Fig. 3 isa "iew in. section through one of the frame members; Figs. 4 and 5 are 6 is a view in views in section showing different manners of attaching springs to the strips; and Fig.

detail of afurther modification.

In spring constructions in theclass above referred to, the body springs are usually upright spiral coils as indicated at 1 whose top convolutions 2 are secured in place by attachment to a rim frame 3. In the 0011-; struction herein shown the latter is a metal strip or bar having a flange 4 thereon 1on gitudinally disposed in a plane transverse to the plane of the body of the strip. As indicated in Fig. 1 where the strip is used for a rim frame thebody of the strip rests on the top convolutions 20f the springs, which contact also with the longitudinal flange. The marginal portion of the latter adjacent the point of contact with each spring 1s bent over the spring toward the base of the strip. This forms a retaining part 7 which secures the coil firmly in place. The portion 7 usually forced into place with a swaging v .Speeificationof Lettcrs ratent.

- tool which usually is arranged to shear the part 7 from the bodyof the :flange as indimar'gin to theflange. The base frame as indicated in Fig. 2 may also be formed in' a the same manner asthe I'1Il1 frame.

ously,.the portlon 7 may be made to bear Obvitangential-ly only against the spring as in Fig. 3-'or it may be bent to closely embrace the spring as in Fig, 4. As the strips are usual marginal or central and if central as in Figs. 4 and 5, it is usually double walled in which case one of the walls is pressed out at the-point of contact with the spring to form the ton e. I In Fig; 5, the body of the strip is up- .rig-ht'sand one of its margins is inbent around the spring. When used as a base frame construction, the bending down or. interrupting of the marginal flange necessarily weakens the latter and this is. compensated for by the spring itself whose coil held in contact with the member acts as a reinforcement to the weakened zone. method of construction the use of clips or not wish to'limit myself to any particular form or arrangement of parts.

I claim as my invention p 1. In a spring construction, a frame member having a longitudinal flange in a plane transverse to the plane of the body of the member, and springs disposed thereon, a convolution-of each spring contacting with the body and flange of the member and the margin of the flange being interrupted adjacent the contacting portion of the spring with an off-set that is bent over the contiguous spring.

'2. In spring constructions, sheet metal strips provided with longitudinal flanges transverse to the body of the strip, and springs each having a convolution resting cated in Figs. '2, 3, 4 and 5. Otherwise it maybend over a portion ofvthe flange, and

in both instances it leaves an interrupted,

the margin of the flange and being bent around the spring. v

In a spring construction, upright body springs and a rim frame consisting of flanged strips resting on the top convolutions of the springs 'with their flanges in contact therewith, the marginal portions of the flanges adjacent the springs being in- 4. In a spring construction, upright body springs and a rim frame consisting of flanged strips resting on the top convolutions of the springs withtheir flanges in contact therewith, the marginal portipns of the flanges adjacent the springs being inbent around the springs, and the portion of the.

convolution of each spring that bears against the body of the strip being adapted to reinforce the strip at the point of interflange resting on the top con olutions of the springs which contact also with the other flanges, the marginal portions of the latter fla e adjacent each contacting spring being Imnt around the spring and forminginterruptions to the margins'of the flange itself.

In testimony whereof I aflix my signature in presence of two witnesses.
