SPRING BED BOTTOM. l No. 296,672. Patented Apljf, 1884.
T? l A UNITED STATES PATENT OFFICE.
Y SANFORD S. BURR, OF INNETKA, ILLINOIS.
SPRING BED-BOTTOM.
SPECIFICATION forming part of Letters Patent No. 296,672, dated April 8, 1884.
Application filed October 10, 1883. (No model.)
To @ZZ whom it may concern.:
Be it known that I, SANFORD S. BURR, a citizen of the United States, residing at `Winnet ka, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring Bed-Bottoms, of which I do declare4 the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
In an application for Letters Patent filed of even date herewith I have described and claimed improved means whereby the springs of bedbottorns can be readily adj usted to cornpensate for any irregularities or depressions due to the sagging of the cover oi the bottom. In the invention set out in said application the adjustment of the springs and cover of the bed-bottom was affected by straightening the supporting strips or rods upon which the springs rested, and thus the springs at such portion of the bed-bottom as had become irregular or depressed might be easily lifted.
My present invention also has for its object the provision of means whereby the springs of bed-bottoms may vbe readily adjusted to compensate for the permanent depression of the springs and sagging of the cover incident to long or severe usage; .but in this case the strips or rods that support the springs are provided with means whereby they can be lifted vertically, so that whether the strips or rods be flexible, as in the application above referred to, or be stiff, the desired adjustment of the springs can be easily effected.
In the accompanying drawings, Figure 1 is a view in vertical longitudinal section of a spring bed-bottom to which my invention has been applied. Fig. 2 is a view in vertical transverse sectiomand Fig. 3 is an inverted plan view, of such bed-bottom. Fig. I is a detail enlarged "view in section, showing a modified form of sustainin g-bolt for the springsupporting strips.
A designates the side bars, A the end bars, and A2 the top bars, of the 'bed-bottom, over which is stretched the cover A3, preferably of woven wire, having its ends held iirmly by the clamp-strips a, secured to the top bars of the main frame. Through the top bars, A2, and held therein by heads b and washers b', descend the bolts B, over the threaded ends of which t the friction-washers b'I and hand-nuts b3, which serve to support and retain in place the spring-sustaining bars C, through the slots or eyes c in the ends of which the bolts pass. These bars C are preferably of thin elastic wood or metal, and may be of any desired number. Upon the bars G rest the slats D, to which are attached the spiral springs e, of
'usual construction, which bear against the under side of the woven-wire cover, and serve to keep the same tightly stretched.
When from any cause, as by long or severe usage, the springs become permanently depressed and the cover slack and irregular, the supporting-bars D can be readily lifted by turning the hand-nuts b2, thus readily adjusting the springs and the cover to their proper position. The bars A not only serve as adjustable supports for the springs, but, being of yielding material, serve the further'function of giving greater elasticity to the bed bottom. By providing the supporting-bars with the means shown for vertical adjustment the springs can be pressed constantly against the coverto uniformly stretch the same.
In Fig. 4 is illustrated a slightly-modified form of this invention, wherein the bolts B are hinged, as at x, to allow greater freedom of movement to the supporting-bars.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a spring bed-bottom, the combination, with the frame and the cover, of the springs located beneath said cover, the longitudinal sustaining-slats for said springs, and adjusting mechanism, arranged substantially as set forth, 4whereby said sustaining-slats can be lifted vertically in order to vary the tension of the springs, substantially as described.
2. In a spring bed-bottom, the combination, with the frame and the cover, of the springs located beneath said cover, the transverse slats for said springs, the longitudinal slats, and means, substantially as described, for adj usting said spring-sustaining slats vertically, whereby the tension'o'i` the springs can be varied, substantially as described.
In testimony whereof I have hereunto set my hand,
SANFORD S. BURR.
