UPHOLSTERY SPRING CONSTRUCTION.

" Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed February 10, 1919. Serial No. 276,225.

To all whom it may concern:

Be it known that I, LEONARD A. YOUN% a e.- troit, Wayne County, Michigan, have in vented certain new and useful Improvements in Upholstery Spring Construction, of which the followlng is a full, clear, and exact specification.

In the use of sprin seats, it is advisable that the springs be a orded such support as.

to carry the load easily under normal shock, and at the same time be capable of resisting severe impacts, as when the vehicle in which the construction is used is traversing rough roads, in such a manner as to cushion the occupant against unnecessary jolting.

This invention includes means whereby the springs are not only given ample support, but also are yieldingly maintained, so that the occupant, if the springs are fully compressed, does not feel the jolt of a rigid, or non-elastic base, such as is usually used to support springs.

A further advantage of the construction is the shielding of the interior from dust and lodgment of foreign articles when the seats are removed, while the appearance is good and the parts assembled with a minimum of cost of labor and material.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a plan view with the upholstery covering removed and partially broken away of a construction that embodies features of'the invention:

Fig. 2 is a view in section and in detail of a portion of the construction;

Fig. 3 is a view in section and detail showing a modification of the construction;

Fig. 4 is a plan view of a seat showing the application of the upholstery, partially broken away;

Fig. 5 is a view in section and in detail showing a modification of the base;*

Fig. 6 is a view in form of securing and holding band,

Referring to the formed of transverse strips 2 'of wood or light, thin, resilient material, that are bound along front end marginal portions by a U shaped strip 3 of sheet metal that is detail showing one drawings, a base-1 is clenched upon them, and is carried around the corners, as at i if desired, while a rear strip 5 similarly secures the rear end marginal portions together.

The assembled base 1 is given the contour desired to have it meet the requirements of a frame of any desired dimensions an shape.

A plurality of upright spiral springs 6 are mounted on the base strips. These may be conoidal as indicated, or they may be of the hour-glass type, or of any preferred design suitable for the purpose. The base turn 8 of these springs may be stapled, or otherwise secured to the strips of the base; but preferably they are each held in pliable flat metal bands 9 that are supported on the base. Tacks may be used to hold the strips inposition, or in the preferred form of construction, the end portions of the bands are cut transversely and spurs 11 are bent down therefrom, and riveted through the base strips. Likewise the method of securing the springs to the flat bands may be varied as desired. As herein indicated, each base coil 8 is passed under a tongue 13 struck up from the face of the band, and beneath the band and between the band and a tongue 14, the tongue being clenched as desired.

A rim frame 15 may encircle the outer springs and is secured to the outer upper turns'thereof, clips 17 being used, or other suitable means, to secure the parts together.

' The tops of the springs may be stayed by cross-connections, or the latter may be omitted.

'The usual upholstery filling or cushion body 18 is laid on the springs and a cover 19 placed thereon with a depending apron 20 cured, while below, a groove is used to retain dec the enlarged or welt edge 5 of the apron, the latter being inserted therein and the strip clenched upon it in the usual manner, or the groove of the strip may merely afford an interlock engagement with the inserted welt. When it is desired to prevent any sidewise movement of the individual resilient strips 2, the U-strips 3 and 5 may be crimped between the strips, as shown at 26 in Fig. 5.

As a result of this construction, the spring seat has a closed base, which afi'ords perfect support for the springs and gives ease to the occupant when the resilient springs yield to a sudden jar, which brings the tops of the springs of the upholstery into contact with the base, the latter cushioning the shock, since the strips bend readily and individually, as they are connected together at the ends only.

Furthermore the base is a shield that prevents any large foreign substance working into the springs and gettingentangled therewith, while the finish is such that the unsightly underside of the upholstery is concealed when the spring seats are removed.

Obviously, changes in details of construction may be made without departing'from the spirit of the invention, and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is 1. In an upholstery spring construction a base formed of resilient strips, means securing the strips along the end margins thereof to form a closed seat bottom, springs mounted on the base, upholstery on the springs and a cover for the upholstery having a depending apron secured along the, margin thereof to the base.

2. In an upholstery spring construction a base formed of resilient strips in juxtaposition, means securing together along the end margins thereof, upright coil springs, and a cover for the upholstery having a depending portion engaged along the lower margin thereof to the strip securing means.

3. In an upholstery spring construction, a base formed of resilient strips in juxtaposition secured along the marginal end ortions thereof by a sheet metal strip, uprigl it spiral springs mounted on the resilient strips, upholstery on the springs, and a cover thereon having a depending apron secured along the margin thereof to the base.

4. In an upholstery spring construction, resilient base strips in juxtaposition, U-strips embracin the marginal end portions of the strips and securing them together, upright spiral springs mounted on the resilient strips, upholstery on the springs and a cover therefor having a depending apron secured along the lower margin to the base strips.

5 In an upholstery spring construction a resilient base, sheet metal bands supported on the base, upright spiral springs supported on the base and interlocked with the bands, upholstery on the springs, and a cover for the upholstery with a depending margin portion secured to the base.

6. In an upholstery spring construction, resilient strips, U-strips embracing the marginal end portions thereof and securing the strips in juxtaposition, sheet metal bands on the resilient strips, upright spiral springs supported by the base strips and secured by the bands, upholstery on the springs and a cover for the upholstery having a depending portion, the margin of which is secured to the base strips.

7. In an upholstery spring construction, resilient base strips in juxtaposition, binding strips, each having a pair of flanges between whiclrthe end marginal portions of the resilient strips are secured, sheet metal bands secured on the resilient strips and provided with struck out spring retaining portions, upright spiral springs the base turns of which interlock with the struck out portions of the bands, the strips affording support for the bands and springs, and upholstery on the springs. v

8. In an upholstery spring construction, resilient spring supporting strips, binding strips each having a pair of spaced flanges between which the end marginal portions of the resilient strips are secured in juxtaposition, the binding stripsbeing formed with a Welt receiving groove, sheet metal bands lying on the resilient strips, upright springs interlocking with the bands, upholstery on the springs, and a cover therefor having a depending portion, a margin of which is secured in the welt receiving groove.

9. In a spring seat construction, a resilient base formed of strips in juxtaposition secured along the margin end portions thereof by binding strips which embrace them, sheet metal bands on the resilient strips having spurs struck from them that penetrate the strips and secure the bands in position and upright spiral springs secured in position on 11. In an upholstery spring construction,

resilient basestrips in juxtaposition, U-strips embracing the marginal end portions of the strips and securing them together, a Welt receiving groove in each U-strip, upright springs on the strips, upholstery on the springs, and a cover therefor having an ties thereof only, each strip being free to flex apron with welted edge secured in said between the end securing means independgrooves. ently of the adjacent strips, upright coil 10 12. In an upholstery spring construction, springs and means for securing the springs resilient base strips in juxtaposition forming on the strips.
