This invention relates to furniture and more particularly to a bed spring.

Many persons object to a double bed as the spring has a tendency to sag in the middle and also due to the fact that large sheets and blankets must be used which are not only hard to handle but are also expensive. Twin beds have been used but many do not find them practical as they require extra room.

Therefore, one object of the invention is to provide a spring for use upon a double bed so constructed that separate mattresses may be supported thereon and thereby provide the convenience of individual beds.

Another object of the invention is to provide a bed spring including a frame of the proper size to lit a double bed and so con structed that it will be very strong and rigid.

Another object of the invention is to provide the spring with mattress supporting units which are entirely separate from each other and spaced from each other transversely of the frame a sufficient distance to allow sheets, blankets and the like to be easily tucked under mattresses supported thereby without interference.

The invention is illustrated in the accompanying drawings, in which:

Figure l is a top plan view of the improved bed spring.

Figure 2 is a transverse sectional view through the spring taken on the line 22 of Figure 1.

Figure 3 is a longitudinal sectional view through the spring.

Figure 4 is an. end elevation of a modified form of spring.

Figure 5 is a perspective view of one of the brackets shown in Figures 2 and 4.

Figure 6 is an end elevation of another modified form of spring.

The improved bed spring includes a frame having side bars 1 and a center bar 2 which extend the full length of the frame and may be either solid or of a tubuular construction. Brackets 3 and 4 are carried by the ends of the bars 1 and 2 and each is firmly secured upon the end of the bar to which it is applied.

Each of the brackets 4 is provided with a "duplicat may be secured.

sleeve 5 which fits tightly upon the bar'2 and arms 6 extending upwardly at an outward incline transversely of the bar and each terminating in a fiat head 7. The brackets 3 are formed of strong sheet metal and each has its lower portion formed with an opening 8 to receive 'it-is applied and a corner "to form a shoulder 9 and prevent the bracket from slipping the end of the bar 1 to which portion removed when set upon a ledge of a bed rail. The heads 7 of the brackets 4' and the upper ends of the brackets 3 fit flat "against the depending flanges 10 of the end bars 11 where they are secured by rivets 12, "so thatthey will be firmly secured to the end bars; If so desired, formed in sections a each end bar may be s shown in Figure 4, where the two sections are indicated at 11'. In this figure there has also been shown bearing rods 13 which connect the brackets 3 "and 4;.

The mattress supporting units are of a e construction and each includes end strips 14 connected by side strips 15 thereby defining rectangular frames to which a fabric 16, upon which a mattress is to rest, This fabric may be formed of links joined together, as shown in Figure 1, or interwoven wires or the like. Coiled springs 17 connect the end strips 14 with the

end bars

11 or 11 and, therefore, the mattress supporting units or elements will be yieldably connected with the end bars of the frame and allowed to have sufficient give to yieldably support a mattress.

When this improved bed spring is in use, it is set in place in the usual manner and the shoulders 9 of the brackets 3 rest upon side rails of a bed. The mattresses rest upon the mattress supporting units an may be applied in the usu tucked in at the lower ends sides of the mattresses.

a1 manner and and along both I have, therefore, upon a double bed having all of the a without requiring more space 1n a room than a double bed of a conventional construction and size.

In Figure 6, there has been shown a modified form of the invention.

01 bed covering In this figure,

dvantages of separate beds the numerals ,18 represent box springs of .a conventional construction. These box springs rest upon a suitable number of cross bars 19 spaced from each other longitudinally of the box springs and the cross bars at the ends of the box springs carry depending cleats 20 to bear against side rails of a bed upon which the cross bars rest and prevent transverse shifting. 10 Having thus described the invention, I claim:

1. A bed spring comprising a frame having side bars, and a center bar extending V longitudinally of the frame, end bars disposed in transverse relation to the side bars and center bar and above their ends, brackets 7 carried by the side bars at their ends and extending upwardly therefrom and secured to the end bars, brackets secured tightly about the'ends of the center bar and each having arms extending upwardly from opposite sides of the center bar in diverging relation to each other and secured to the adjacent 1 end bar,,mattress supporting units extending between said end bars t opposite sides of said'center bar, and springs connecting said units with the end bars. 7 '2. A bed spring comprising a frame having side bars, and a center bar ext-ending longitudinally of the frame, end bars dis posed in transverse relation to the side bars nd the center bar and above their ends, brackets carried by the side bars at their ends and each having its lower portion engaged tightly about a bar and its upper end secured to the adjacent end bar, brackets secured tightly about the ends of the center bar and each having arms extending upwardly from opposite sides of the center bar in diverging relation to each other and secured to the adjacent end bar, rods extending between the brackets of the center bar and side bars and constituting braces, mat- V tress supporting units extending between said end bars at opposite sides of said center bar, and springs connecting said units with the end bars.

In testimony whereof I affix my signature. MOSES L. COHN. [1,. s.]
