UPHOLSTERED SPRING STRUCTURE.

Application led December 7,1922. Serial No. 605,489.

To all 'whom t may concern:

Be it known that l, Dnsmn H. VAN Hovn, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Upholstered Spring Structures, of which the following is a specification.

vThe invention relates to an upholstered spring structure.

T he object of the present invention is to provide for upholstered spring structures,

a base frame equipped with means for sup porting the spring structure and for securing the marginal springs to the base Jframe and to the marginal springs at the lower ends thereof.

A further object of the invention is to pro-y vide a base frame of this character adapted to hold the leather or other material, of which the leXible covering is constructed, smoothly in position so as to present a neat finish7 and to protect the flexible covering from wear, abrasion or other injury at the point of attachment of the covering to the base frame and to the spring structure.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion and minor details of construction, te within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

ln the drawings, in which like characters e0 of reference designate corresponding parts in the several viewst Figure 1 is a vertical sectional view of a portion of a spring structure provided with a marginal base frame constructed in accordae ance with this invention. l Figure 2 is an enlarged detail sectional erspective view of a portion of the base rame illustrating the manner of attaching the marginal springs and the Flexible coverer ine.

igure 3 is a detail perspectivevlew ol' a portion of the main strip.

Figure l is a similar view of a portion of the auxiliary interlocking, clamping strip.

e5 ln the accompanying drawing, in which is illustrated the preferred embodiment ot the invention, the base frame comprises in its contruction a main strip l and an auxiliary interlocking clamping strip 2 constructed of sheet metal or other suitable material and designed in practice to extend around the `four or more sides of a spring structure, such as a spring seat of an automobile or the like. The main strip is composed of upper and lower approximately horizontal sides 3 and 4, and an inner connecting portion or bend 5. The upper and lower sides 3 and 4 are spaced apart to form an approximately U-shaped body portion, and the lower side Ll, which is extended outwardly beyond the upper side, is provided at the outer edge with an upwardly, extending longitudinal ange 6, which is nearly vertical and which is adapted to be compressed or bent inwardly to close the space between the upper and lower sides 3 and Il at the outer portion of the main strip to conne the lower marginal portion 7 of a flexible covering 8 in the longitudinal opening or space between the upper and lower sides of the main strip. The main strip in practice is preferably constructed of heavy material, and the narrow upper Side 3 is provided with an upwardly extend ing approximately vertical flange 9, which spaced from the upwardly extending flangi- 6 of the lower side. before the said flange il is bent inwardly to confine the marginal por, tion of the flexible covering within the main strip for fastening the said marginal cover ing to the base frame. The marginal portion of the flexible covering 8 is preferably provided with a hem l0 formed by folding the material on itself and stitching the folded portion and a core ll, consisting of a rod of metal or wood, or other suitable material, is preferably arranged within the hem to provide a bead or vmarginal enlargement, 'which is confined within the main strip and which eilectually prevents'the exible covering from accidentally slipping out of the base frame', The marginal portion ot the illexible covering may be constructed in any other desired manner as will be readily un derstood.

rlhe interlocking auxiliary strip 2, which is reversely arranged with respect to the main strip, is composed of upper and lower spaced sides and an outer curved connecting portion or bend 12, which presents a smooth i supporting surface to the flexible covering 8 at the attached marginal portion thereof, and it enables the flexible covering to be stretrhed taut without liability of tearing or otherwise-injuring the flexible covering. This also enables the flexible covering to be maintained in a smooth neat condition at the point of attachment to the base frame. The lower side of the auxiliary clamping strip extends into the main strip and fits against the inner o1' lower face of the upper side of the said main strip, while the inner face of the bent or connecting portion 12 fits against and is braced by the upwardly extending flange 9 of the said upper side 3 of' the main strip. The upper side of the auxiliary clamping strip is adapted to be compressed or pinched around the upper and innerside faces of the lower end coils 13 of the coiled or volute springs 14 of the spring structure and the compressed or pinched portions 15 of the upper side of the auxiliary strip se curely fastens the marginal springs upon the main strip of the base frame, which supports the said marginal springs. The spring structure, which may be of any preferred construction, consists of rows of the said coiled or volute springs coupled or otherwise connected together at their upper and lower ends and preferably provided at their upper ends with a marginal frame 16.

The main and auxiliary strips are adapted to be easily and quickly assembled, and the said strips may be readily compressed to fasten the marginal springs and the marginal portion of the flexible covering to the base frame.

`What is claimed is:

1. In a spring structure, a base frame comprising a main approximately U-shaped strip having spaced upper and lower sides and an inner connecting portion and provided at the outer edges of the sides with projecting anges. the flange of the lower side being adapted to be bent towards the upper side to close the space between'the said sides to confine a flexible covering therein, and a reversely arranged auxiliary clamping strip interloclred with the main strip and having an exterior flange adapted to be compressed around the upper and inner faces of the lower end coils of the marginal springs of a spring structure to secure the marginal springs upon the main strip.

2. ln a spring structure including a base frame comprising a main strip approximately U-shaped in cross section having spaced upper and lower sides, the lower side being extended outwardly beyond the upper side and the said sides being provided at their outer edges with projecting longitudinal flanges. the flange of the lower side being adapted to be bent inwardly towards the upper side to confine a flexible covering in thev main strip and an auxiliary clamping strip interlocked with the main strip and having an exterior flange located above the upper side of the main strip and adapted to becompressed around the lower end coils of the marginal springs of a spring structure.

3. In a spring structure'including a base frame comprising a main strip approximately U-shaped in cross section having spaced upper and lower sides, the lower side being extended outwardly beyond the upper side and the said sides being provided atA their outer edges with projecting longitudinal flanges, the flange of the lower side being adapted to be bent inwardly towards the upper side to confine a flexible covering in the main strip, and a reversely arranged auxiliary clamping strip approximately- U-shaped in cross section having upper and lower sides, the lower side extending into the main strip and the upper side being located above the same and adapted to be compressed around the lower end coils of the marginal springs of a spring structure to secure the marginal springs upon the main strip.

4. In a springl structure including a base frame comprising a` main strip approximately U-shaped in cross sectionhaving spaced upper and lower sides, the lower side being extended outwardly beyond the upper side and the said sides being provided at their outer edges with projecting longitudinal flanges, the flange of the lower side being adapted to be bent inwardly towards the upper side to confine a flexible covering in' the main strip, and a reversely arranged auxiliary clamping strip composed of upper and lower sides and an outer connecting portion fitted against and braced by the upwardly extending flange of the upper sideof the main strip and presenting a. convex ex'- terior surface to the flexible covering, said auxiliary clamping strip having its lower side extending into the main strip and its upper side located above the same and adapted to be compressed to clamp springs of a spring structure on the main strip.

5. In a spring structure, a main strip of approximately U-shape, having upper and lower sides and provided at the upper side with a substantially vertical projecting longitudinal flange and an auxiliary clamping strip of approximately U-shape reversely arranged with respect to the main strip and having its lower side 'extending into the main strip and its upper side located above the same. said auxiliary clamping strip fitting against the said flange and braced by the same and adapted to clamp springs on the main strip.
