SPRING-BED.

Specification 01? Letters Patent. Patented J an; 24, 1911.

Applieationflled March 3, 1910. Serial No. 547,158.

To all whom it may concern: I

Be it known that I, EDWARD Ronsnri, a

citizen of the United States,.residing at his Angeles, in the county of Los Angeles and State of California, have invented a new and useful Spring-Bed, of which .the following is a specification. 4

This invention relates tospring beds which are adapted to accommodate two persons, and the main object of the invention is tofprovide such a bed with means whereby the two sides of the spring bed are rendered moreor less independent, so that excessive weight on one side of the bed will not materially affect the other side ofthe bed.

" Where two persons of different weights are usin a spring. bed, the bed tends tosa towart the side where the greater weight-is laced, resulting in the inconvenience of the ighter persontending to rolltoward the opposite side, and the present invention is 'dil rectedto obviate this defect.

Another object ofthe invention is to provide a spring bed of the abox'edcscribed character with means for substantially .cqnalizingtl'ie tension orelasticity of the bed throughout its width.

Other objects of the invention will appear hereinafter.

Referring to the drawings :Figure .1 is a plan of thespring bed; with parts broken away;- Fig. 2 is a transverse section on line oa -m Fig. 1.

The bed comprises a frame having longitudinal members 1 and cross bars 2 at each end thereof, and a bed spring 3 secured to and stretched between ,Silld cross pieces.

Said bed. spring preferably consists of a woven wire web'orfabric having-its end portions gripped by suitable clamping means 4'at each end of the bed frame or otherwise secured tothe cross members 2. Said bed spring isconstructed so asto overla'p along the central portion of the bed and this is preferably effected by doubling the .woven wire back and forth on itself so as to form two oppositely extending superposed loops or overlap portions indicated at 6, 6 in Fig. 2, said loops or overlap portions- 6 overlying the overlap portions 6'.

A reinforcing member consisting of a rope or strand Of-COllGd. wire, indicated at 7,

- extends within each of the loops 6, 6. at the "bend'thereof so that the bed spring 3 passes over'and around one of said ropes andthen back over and'around the other of said ropes, then forwardly below the two layerstirst formed to the other side of the bed,

and is secured at its end by the clamping means 4 so as to efiectively support the inner end of each loopand to divide the spring bed into two portions 3', 3", the portion?! extending over one side of the bed to the bend of the loopv 6, and the portion 3 ex tending over the opposite edge of the bed to the bend of loop'6.-

The triple thickness of web. provided at the overlaps or loops'6 together with the reinforcing means 7- provides for considerably greater stiffness at the central portion of the bed than at the side portions, and to equa,lize,'as far as necessary, the stiffness throughout thcbed, I prefer to provide ad- 5 ditional reinforcing means consisting of longitudinal wires 8 tensioned, by coiled springs 9 secured by wires 10 to the respective end members 2. The reinforcing wires 8 preferably extend through the woven wire mesh as indicated in Fig. 2 to enable "them to more efiectively'support the bed.

A stiffening rope or reinforeim means consisting of a portion of the width of the spring bedrolled upon itself as shown at 10, and with a'core strand 11, is provided at each sideof the bed to stiffen the edge thereof.

' By reason of the independent support of the: two sides 3', 3 of the bed, by means of the loops 6, 6, each side of the bed may yield more or less independently of the other web is of advantage in that, in case 0 saging of one side of the bed, no opening is orrned through which bed clothes or any part of the occupants person might protrude.

What I claim is: 1. A s ring bed comprisin a frame, two

"longitudinal reinforcing mem ers extending between and secured to the ends of the frame near the midwidth of the bed, and a bed spring secured to and extending between the ends of the frame, said'bed spring being bent over and around one of said reinforc-- g with the bend of each of said 1oops,'and reing members, and then back over and Enforcing means for said elastic fabric along around the other of said reinforcing men 1 each side thereof.
