To all 'whom it may concern.: y 1 Y l Be it known that l, JOHN H. Premier, a

` citizenof the United States, and a resident of Bengies,

.y for varying v lan A increasing'the e Aes contempla-tes a in 'the county' of Baltimore and State of Maryland, have invented certain new and useful Improvements-in -BedfBottoms, of which-thel followingis a specifica-v tion. v

My invention relates' to bed "bot-tomsof the kind provided with aflexibleimember of wire, rope,or the like,hereinafter 'conveniently described as a cable and which is normally'maintained under ltension forithe purpose of supporting the mattress and relatedV parts of the bed.

cable is extended back and forth lengthwise 'or crosswise of thebed bottom, and in which v the tension of the cable is distributed and equalized automatically;

vMy invention further comprehends a bed bottom provided'iwith improved mechanism My invention also coinprehends an improved casing, mounted telescopicallyj in position, for the My invention' likewise contemplates quite a number lof distinct improvements related to' bed bottoms ciency" thereof. Reference is made to the accompanying drawing forming a art of-*thi's 'specification, and in whichf li e lett/ers indicate like parts.

Figure 1'is a plan view ofthe bed'bottom complete; Fig. 2 isa entary section, taken on the. line 21-2of .ig..1 looking 'in 'casing 11 having the direction of the-arrow; and fragmentary section' on :the line -3--3-'01 Fig'.

I provide a pair of 'tubular 'sleeves 4- and into each of Vthese-I telescopically'" fit twofvhars 5, each bar 5 being providedwith a threaded portion 6 fand 'with 'a square por-'- ytion 7. Enga'gingopposite sides of the square portions 7 are vangle bars 8 provided with flanges' 9 extending outwardly there from, as will be. iind erstood from Fig. 2; The angle bars 8 are secured to the square portions 7 by aidofbolts or rivets' 10.'

a substantially semi-cylindrical form is v`provided with flanges 12 integral therewith and 11 is made of spring More particularly stated, invention bed bottom in which a single at will the tension of the cable.`

A metaland so formed that it may be slid or telescoped onto the flanges '9 .by `pushing .end wise'against it, the-parts being otherwise in the relati-ve'positions indicated in Fig. 2. Between the angle bars 8, l also place spacing sleeves 13l and extending through these' sleeves are bolts or rivets 14. The spacing sleeves 13, together with the square portions 7 of the bars ,5, maintain the angle bars 8 at a uniform distance from each other throughout= their entire length.

AAt each end of each sleeve 4 and encircling the-adjacent portions .of the bars 5, Iv

spacing place annular-'washers 15. Engaging these Washers are spiral compression springs 16 and engaging these springs are washers 17 vheldvin position underinore or less tension by rotary nuts 18 .which are mounted upon Athe threaded portions 6. I provide a nmber of'rollers 21 groove 22. and carrying a stub shaft 23., this -eachhaving a peripheral stub shaft extending' axially through the roller and being rigid relativelyto the same -so that each roller with its stub shaft acts as 1 unit. Between the anglebars' is a space l -24 into which the rollers 21`extend' for av slight distance. The cable is shown at 25 and is secured. at its ends by loops 26 which extend through holes 27)in,one of the angle bars 8. i
