SPRING-BED.

kmattress fabric is supported on the upper ends of vertically arranged. coiled springs whichA are mounted on a frame, the object of the invention being to provide an Vimproved bed spring of thisclass which obviates the swaying motion that has heretofore been an objectionable feature in such spring beds; which provides means to keep Vthe mattress fabric level .when the bedis the mattress fabric sti and under tension at all times; which stiffens the edges'of the mattress fabric when the bed is in use and so that a person can lie on the same without danger of rolling olf which enables the tension on the edge wiretobe varied as may be desired; and which consists of parts thatv are adapted to be readily assembled and disassembled so as togreatly facilita-.te packing,

storing and shipping the said-spring beds.

The invention consists in the construction,

combination and arrangement of devicesv hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a longitudinal sectional view of a spring bed constructed in accordance with my invention. Fig. 2'is a vertical transverse seci 'tional view of the same. Fig. 3 is a detail perspective view of one corner of the same. IFig. 4 is a detail horizontal sectional view of the same on the plane indicated by the line a-a of 3. Fig. 5 is a detail vertical sectional vlew of the same on the plane indicated by the line Z -b of Fig. 3.

The base, supporting frame of my 1mproved spring bed comprises a pair of longitudinally arranged side bars 1 which are made of angle iron and a series of transverse bars 2, which are also referably made of iron and which have their ends bent at right angles as at 3. and riveted to the inner sides of the vertical websofthe angle iron side bars 1. The coiled springs 4 which bear under the wire mattress fabric 5 have their lower ends secured on the cross bars 2 at suitable points, any suitable number of said v coiled springs being employed,

wires 7 This mattress fabric is provided with l,an endless edge wire 8 of suitable 'gage andwhich` extends around the ends and sides of themattress fabric.

My invention relates especially to im- ',proved means for engaging the edge wire and holding the same under tension, to keep the mattress fabric level when not in use and to prevent the same from sagging at the sideswhen not in use and to also ccoperate with the coiled springs in the support of the mattress fabric andthe weight of the person or persons using the bed.

In accordance with my invention I provide a bracket 9 for each corner of the bed. Each bracket is a single casting, comprising a base 10 to bear on one of the bars 1, at one end of the same, and an upstanding out -wardly extending curved arm 11. The arm its under side, near its inner end, with a downwardly extending stud 14 to enter an opening punched in the bar 1 and Said base is provided at its outer end with a downwardly extended and inturned 'flange 15 to engage the end of said bar as shown'. The brackets while thus firmly connected to the ends of the bars 1 by their studs 14 and flanges 15 may be readily detached from said bars, when taking down-the bed, no rivets or other fastening devices being employed lfor this purpose.

The corners of the edge `wire 8 are slidably engaged in the rounded grooves 16 in the outer sides and near the upper ends of the lever standards 17. One vof these lever standards is provided for `each 'bracket 9 and is arranged in the space between the lugs 12 and provided at a suitable distance from its upper end with trunnions-18 which engage in the slots 13 of said lugs so that the lever standards are detachably pivotally mounted in the brackets and may be readily mounted therein or removed therefrom.

Coiled retractile springs 19 are provided y the bars as at which are spaced from the ends ofthe barsI 1'. and as connected vto the lower ends of the lever standards by links 2l and eyes v22,l the latter being. en-

gaged with notches'23 near thelower ends of the lever standards andsaidvlink :wires extending-through and bein'g freely slidable in 'openings 24 in the bearingsat the ends 'of the frame. The tensioning spring 19 may be of any suitable.` gage`and strength according to the desired tension of the edge wire 8. The lever standards may bereadily disconnected .from the spring 19 by 1ner e,ly discharging' their lower ends from the llnk-v eyes, when taking down the bed for purposes of-repair, storage, transportation or the like. I also provide braces 26 to coperate with the lever standards 'and spring 19 in impart- ,f

' ing the requisite tension 'to the edge wire.

` 28 and is thereby forked andfadapted to bear on a guide wire 29 which connects two of the bars 2. A 'coiled retractile sp1-ing 3i) is mounted on .each guiderwire and bears at one end against one of the bars 2 and at the Vother end against the forked inner end of the brace andhence the said springs press the braces outwardly and cause the latter to coperate with the edge. wire under stress. When disassembling the spring bed the -braces 26 may be readily lifted and disconnected from the. guide wires, as will be un-v derstood. A y ,Havlng thus described my. invention,'lI
