(Cl. .5-e-262) This invention relates to spring bed bottoms, bed springs or the like and more particularly to means for stabilizing the movement of a top frame of a bed spring with reference to a bot5 tom frame which, through interposed springs,support the top frame. An important object of the present invention is to provide novel and advantageous stabilizing means of the general character speci?ed. 10 One important feature of the present invention involves the use at a desired position along Fig. -'7 is a plan view of the structure illustrated in Fig. 6. ‘Referring to the drawings, the spring bed bot tom comprises an upper ‘frame iii preferably com posed of angle metal, a lower frame I! which ; may also be formed of angle metal, and coil com pression springs l2 interposed in a suitable man ner between end bars iii of the upper frame it and end ones of the cross bars 84 of the lower frame H as shown in Fig. 1 to assist in the sup- 1 w port of the upper frame from the lower. The a bed spring of a cross member which is spring end bars of the lower frame H are suggested by supported from the bottom frame, and spring stabilizing devices interposed between the cross the broken horizontal line at the left of Fig. 1, extending from that frame. Further support 15 member and the upper frame, the spring stabiliz- ing devices supported by the cross member being desirably weaker than the spring supports for the cross member whereby for light stresses the spring stabilizing devices substantially alone 20 are adapted to give, although also there may be of the upper frame II] from the lower frame is ;. obtained by additional coil springs i2 which are Within the two frames and are supported by ad ditional cross-bars, such as l4, (Fig. 2), connect; ing the opposite side rails of the lower frame. Such use of coil springs, as l2, throughout a bed A comparatively a very slight give to the spring supports for the cross-member, but these will yield to a greater extent under greater stresses imposed on the spring stabilizing devices, with bottom or similar structure and supported on cross bars I4 is well known in the art and re quires no further illustration. ‘Stabilization of the upper frame ill with ref the result that any up or down movement of such cross-member is minimized and is not as great erence to- the lower frame I! may be effected by use of one or more stabilizing assemblages, two being illustrated in Fig- 2- ACCOTdiHg '60 the pre as the up or down movement of the top frame.

Referring to the modi?cation illustrated in Figs. 6 and 7, it will be seen that it differs from that of Figs. 4 and 5 only in arranging springs l6b, diverging from the end of cross member l5b, in a vertical plane and in securing their outer weight is removed.
