SPRING BED.

Application filed. February 4, 1922. Serial No. 534,044.

T 0 all whom it may concern:

Be it known that I, ARTHUR B. MASTERS, a citizen of the United States of America, residing at Boise city, in the county of Ada and State of Idaho, have invented certain new and useful Improvements in Spring Beds, of which the following is a specification.

This invention relates to means for effecting resilient tensioning of the web or fabric of a spring bed'bottom, and more especially to that type of webs or fabric which are connected by a plurality of coiled end springs with the respective cross rails of the bed bottom, an example of which forms the subject matter of my prior Letters Patent No. 1,253,858, dated Jan. 15, 1918. The present improvement has for its object:

To provide a structural formation and association of the parts of the adjusting 7 means whereby the desired degree of tensioning of the bed bottom web or fabric isattained in an effective and accurate manner, and with which a supplementary or independent resilient action in the adjusting means is provided, with the main portion of the mechanism enclosed from view, from accumulations of dirt and from accidental injury, all as will hereinafter more fully appear.

I11 the accompanying drawing Fig. 1 is a side elevation of a bed bottom illustrating the general arrangement of parts in the present improvement.

Fig. 2, is an enlarged detail sectional elevation of a cross rail, adjusting means and accessories at one end of the structure.

Fig. 3, is a similar view of the opposite end of the structin'e.

Fig. 1, is a detail transverse section on line 4+4: Fig. 2.

Like reference numerals parts in the different views.

Referring to the drawing, 1 designates one of the usual spaced longitudinal side rails of the bed bottom, carrying at its respective

ends angle brackets

2 and 3, to which are secured in manner hereinafter described the

end cross rails

4 and 5 of the bed bottom. The

rails

4 and 5 are adapted for end connections with the web or fabric 6 of the bed bottom and preferably in a resilient manner by plurality of coiled springs 7 as shown in Fig. l.

indicate like In the preferred form of the invention the cross rail & is rigidly attached to its .brack-- ets 2, while the companion cross rail 5 is adjustably connected to its brackets 3 by a construction of parts as follows:

8 designates one of a pair of downwardly extending end arms or levers fixedly at tached at their upper ends to the cross rail 5 and pivotally connected at their midlength to the upper ends of the angle brack-' ets 3 aforesaid.

9 designates a coiled sprin arranged in the interior of each longitudinal side rail 1 near the end of the same, and having end abutment against the end web of the angle bracket 3 as shown.

10 designates a screw shaft arranged centrally in the bore of said longitudinal rail 1 and spring 9, and having at its outer end a winged head or button 11 by which convenient manual rotation of the shaft is attained in an adjustment of the parts, and to such end the outer portion of the shaft 10 passes loosely through an orifice in the lower end of depending arm or lever 8 aforesaid, with said head 11 having bearing against said arm or lever as shown.

12 designates a travelling nut or head, having screw threaded engagement with the inner end of the screw shaft 10 and bearing engagement against the inner end of the coiled spring 9, and in the preferred construction shown the tendency of the nut 12 to turn with the shaft 10 is prevented by an engagement of one end of said spring 9 with an orifice in the nut 12, and a corresponding engagement of the other end of the spring with the end web of the angle .bracket 3 as illustrated more particularly in Fig. 2.

With the abovedescribed construction and arrangement of parts an effective andsubstantial adjustment of the parts is attained, with the required. tensioning of the bed bottom fabric or web 6, and at the same time the main portions of the adjusting means are protected frominjury, dirt accumulation and the like.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

In a bed bottom structure, the combination of a tubular longitudinal side rail, angle brackets on the ends of the same, end cross rails supported by said brackets, a.

fabric attached to said cross rails, and an adjustable connection between one of said cross rails and its angle bracket, the same comprising a fixed depending arm on said cross rail having pivotal connection at its midlength to said angle bracket and formed with an enlarged orifice in its lower end, an adjusting screw shaft passing through the enlarged orifice in the lower end of said arm, a screw threaded nut arranged in the tubular end of the aforesaid longitudinal side rail and having operative engagement res/awe with the inner end of said shaft, and a coiled spring arranged intermediate of said. nut and the end web of the angle brackets on said longitudinal side rail, said spring encircling said shaft and having its ends inserted in said web and said nut respectively whereby said nut is hindered from turning as said shaft is rotated Signed at Chicago, Illinois this 1st day of February A. ll, 1922.
