Patented Nov. 8, 1932 UNITED STATES DWIGHT D. RICHARDSON, OF WEST END, NORTH CAROLINA RESILIENT SUPPORT Application filed October 24, 1930. Serial No. 490,950.

This invention relates to a resilient support for chairs, settees, beds, and in fact any articles in which a resilient support may be desired.

An object of my invention is to provide a resilient support for objects, which support may be built into the structure at the time the same is manufactured, or which can be supplied to articles after they have been manufactured and in use in the various fields.

Another object of my invention is to provide a resilient support for articles, said support being adapted to be placed in a bore in a portion of the article, and having a resilient upper portion of rubber or other suitable substance to which a compression spring is slidably secured and to the lower end of the compression spring there is secured, preferably by moulding therewith, a resilient substance,

2 such as rubber or other suitable material, with the intermediate portion of the spring being free. The upper portion of the spring is also free, due to the fact that the material associated therewith is not molded therewith,

thus allowing resiliency to the greater part of the spring. This article is adapted to be placed in a bore and to be held therein by cementing the upper portion in position, or by causing the upper covering to have a snug 3O fit with the upper portion of the bore.

Some of the objects of my invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawing,

showing a preferred embodiment of my invention, in which- Figure 1 is a side elevation of the lower leg portion of a chair, with a portion thereof being broken away to show my invention 40 applied thereto;

Figure 2 is a side elevation of my spring and the resilient material associated therewith, and also showing the cover for the upper portion.

Referring more particularly to the drawing in which like reference characters indicate corresponding parts throughout the drawing, the numeral 10 indicates a bottom portion of a chair post or any other supporting member, which member 10 has a bore 11 therein. In this bore coiled spring 12 is adapted to be secured, and at the top of spring 12 there is the rubber or other suitable material indicated by 13, and integral with 13 but spaced therefrom is a tubular portion 1 1 surrounding the spring, with portion 13 projecting inside the spring. At the bottom of spring 12 there appears portions 15 which is preferably of rubber, which is molded around and intermingled with the lower o end of spring 12, and in normal position the parts occupy the position shown in Figure 1, but when additional weight is carried then portion 15 travels further into bore 11.

In the drawing and specification, I have set forth a preferred embodiment of my invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the-scope of my invention be- .70 ing set forth in the appended claims.

I claim:

1. A resilient support for articles adapted to be secured in a bore in the article, said resilient support comprising a coiled compression spring having resilient material moulded on the lower end thereof, and having resilient material on the inside and outside of the upper end thereof, said upper end being adapted to be secured in the deepest portion of said bore.

7 2. A resilient support for an article of furniture with said article of furniture having a bore extending into one of the supporting portions thereof, a compression spring having means associated therewith whereby the same may be secured in said bore and the other end of said spring having thereon and intermingled therewith a resilient material.

3. A resilient support for an article, with said article having a supporting portion with a bore therein, a compression spring adapted to be secured in said bore and to extend therefrom, a cap member having an interior protuberance adapted to fit Within the upper portion of the spring and the outer sidewalls of said cap member serving to secure the spring to the sidewail portion of said bore, a member intermingled with the lower end of the spring and normally projecting into said bore.

In testimony whereof I aflix my signature.

DWIGHT D. RICHARDSON.
