SPRING BED-BOTTOM.
SPECIFICATION forming part of Letters Patent No. 683,636, dated October 1, 1901.
Application filed November 16, 1900. Serial No. 36,675. (No model.)
To aZZ whom it may concern-.-
Be it known that I, HORACE I'I. BROWN, a subject of the Queen of Great Britain and Ireland, and a resident of the borough of Manhattan, in the city and State of New York, haveinvented a new and useful Improvement in Spring Bed-Bottoms, of which the following is a specification.
My invention relates to an improvement in spring bed-bottoms, and has for its object to provide certain new and improved features of construction and arrangement whereby a very strong and durable bed-bottom is obtained.
A further object is to provide a bed-bottom which is provided with legs, so that it may be used independently of the bedstead when so desired.
A still further object is to provide the weight-supporting surface of the bed-bottom of a plurality of interwoven lateral and longitudinal bands or straps, preferably of spring metalsuch, for instance, as steel-the longitudinal bands or straps being independently adjustable and held under spring-tenmen.
A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a top plan view of the bed-bottom, portions of the bands being broken away in one corner of the bed-bottom to show more clearly the independent adjustable springtension for the longitudinal bands of the bedbottom. Fig. 2 is a side view of the bed-bottom. Fig. 3 is a longitudinal vertical section taken in the plane of the line 3 3 of Fig. 1. Fig. 4 is a transverse vertical section taken in the plane of the line 4 4 of Fig. 1; and Fig. 5 is an enlarged detail vertical longitudinal section showing, on an enlarged scale, the adjustable tension for one of the longitudinal bands.
The frame of the bed-bottom comprises a pair of longitudinal side bars A A, having their opposite ends turned upwardly,as shown at a a, and a pair of end bars B B, which connect and are rigidly secured to the said upturned ends of the side bars.
The bed-bottom is provided with four supporting-legs, so that it may be used without a bedstead when so desired. One pair of legs a a are secured rigidly to the side bar near the opposite ends thereof, and a similar pair of legs-a a are rigidly secured to the side bar A; These legs are preferably made V.- shaped, as shown, having their upper ends secured to the side bars, so as to produce a rigid support for the bed-bottom. Cross-bars O O extend laterally across the bed-bottom and are secured rigidly at their ends to the legs a a and a a respectively, near the lower ends of said legs.
The several parts of the framework of the bed-bottom hereinabove described are preferably formed of angle construction, so that a very strong and yet light construction is obtained.
The longitudinal bands or straps of the bedbottom are denoted by D and the lateral bands or straps by E. These bands or straps are formed from sheet material, except the side longitudinal bands D D which are preferably of rope form for the purpose to be hereinafter set forth. The longitudinal and lateral bands of the bed-bottom are interwoven with each other, but are free to yield with respect to each other, except at the points where the outer ends of the lateral bands E are rigidly secured to the side longitudinal bands D D At the opposite ends of the bed-bottom the longitudinal bands are passed over pulleys or sheaves and thence led downwardly a short distance toward the cross-bars O C,
carried by the legs of the framework. Each of these longitudinal bands is provided with an adjustable spring-tension.
At one end of the bed-bottom I provide a tension-spring d,having one end engaged with the cross-bar C and its other end engaged with the downwardly-turned end of the band or strap. At the other end of the bed-bottom I provide a tension-spring d, having one end secured to the end of the band or strap and its other end secured to an adjustingscrew 0?, which passes through the cross-bar O. I provide the outer end of the adj ustingscrew d with a nut 01 preferably a thumbnut, so that the tension of the spring d, and therefore the band or strap, may be increased or diminished at pleasure independently of the other bands or straps.
The longitudinal bands or straps D intermediate the side bands D D pass over pulleys or sheavesfat the opposite end of the bed-bottom. These pulleys are preferably supported in blocks f, secured rigidly to the end bars in such position that the bed-bottom will be substantially in alinement with the tops of the said bars and a shortdistance above the portions of the side bars A A intermediate of the upturned ends.
To provide the weight-supporting surface of the'bed-bottom of the same width as the framework, I pass each of the ends of the outside longitudinal bands D D around a pair of pulleys or sheaves f f so as to bring the ends of the said outside longitudinal bands to points where they may be engaged by the tension devices hereinbefore described.
The tension-springs,which are engaged with the ends of the exterior longitudinal bands of the bed-bottom, are preferably considerably stronger than the springs of the other tension devices, as it is necessary to keep a much greater strain upon the exterior longitudinal bands than upon the intermediate longitudinal bands, so as to prevent in as much a degree as possible the drawing together of the said exterior longitudinal bands when the bed-bottom is in use.
From the above description it will be seen that I am enabled to provide a structure in which a very smooth surface is provided for the mattress, so that there is no tendency on the part of the bed-bottom to tear the mattress. It will further be seen that each one of the longitudinal bands or straps may be adjusted entirely independently of the others, so that any sag in the bed-bottom may be taken up wherever it appears and also so that one side of the bed-bottom may be brought under a considerably greater strain than the other side of the bed-bottom, if so desired, so as to efficiently support a greater Weight on that side of the bed. It will further be seen that if any one of the straps or bands should become broken it can be readily renewed without interfering with the other bands or straps,
as the parts are completely interchangeable.
It is evident that slight changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but
What I claim is- 1. A spring bed-bottom comprising a suitable framework, interwoven lateral and longitudinal bands or straps, spring-tension devices connectingthe corresponding ends of the longitudinal bands or straps with the framework at one endof the bed-bottom and adjustable spring-tension devices connecting the other corresponding ends of the longitudinal bands or straps with the framework at the other end of the bed-bottom, the said tension devices being located entirelybelow the interwoven portion of the bed-bottom, substantially as set forth.
2. A spring bed-bottom comprising a suitable rigid framework, a plurality of independently-operating sheaves or pulleys secured to each end of the framework, a plurality of interwoven lateral and longitudinal flexible bands or straps, the longitudinal bands or straps being passed over the sheaves or pulleys at the opposite ends of the framework and from thence downwardly and inwardly and spring-tension devices located entirely below the interwoven portion of the bed-bottom for connecting the ends of the longitudinal bands or straps with the framework, substantially as set forth.
3. A spring bed-bottom comprising a rigid frame, consisting of side bars, end bars, supporting-legs secured rigidly to the side bars and cross-bars connecting/the supportinglegs, a plurality of interwoven lateral and longitudinal bands. or straps, sheaves or pulleys carried by the end bars of the frame, over which the longitudinal bands or straps pass and spring-tension devices connecting the downwardly-turned ends of the longitudinal bands with their adjacent cross-bar, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 12th day of November, 1900.
