LATI-RA M. LOVELL, OF SACRAMENTG, CALIFORNIA.

Application filed December 22, 1924. Serial No. 757,516.

ilied springs now in use weaken on their sides and ends and vget outof shape and, when depressed at the sides and ends, the bed spring tends toward uniform yielding u ln other words, when depressing a s idc, practically only that portion of the sprlng where the pressure is applied dcpresses, while the center `remains practicallv normal. d

It is a purpose of the present invention to provide a bed spring which, when pressure is applied thereon, will yield uniform ly throughout its area,in fact, when one side or one end is depressed, the spring will r yield practically the same in the center as the. pressure at the side is distributed toward the center.

Another purpose is to provide a spring which is durable and substantial and in case any part thereof shall become defective or damaged in any way,"the defective part can be removed and a new oneapplied. In fact, new parts can be'supplied by the dealer or the manufacturer. In this way, 'a' spring can be easily repaired at a nominal cost, saving the pricelof an entirely new bed spring. Y Still another purpose is to provide a bed spring `which gives perfect comfort and lvlields'unifnmly to the body andwhen the body moves, it will not impart excessive vi)- brations, nor will there be any encessive loosenessof play of the various parts.

A further purpose is to provide intersecting longitudinal and transverse bars tosupport a plurality of coil 'springs disposed perpendicularly which, in turn, support the upper portion of the bed spring uniformly throughout its area.

A still further purpose is the provision of upper and lower marginal bars with intervening coil springs at the corners of the bed spring, in conjunction with elliptical springs between the side and end bars which,

l when compressed in conjunction with the intersecting transverse and longitudinal bars, act to distribute their yielding action throughout the entire bed spring.

It is to be understood that the particulars herein given are in no way limitative and that, while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances. n The invention comprises further fewures and combinations of parts to be hereinafter set forth, shown in the drawings and claimed. g

In the drawings Figure 1 is a plan view of the improved bed spring constructed in accordance with the invention. I l

Figure 2 is an edge view of the same.

Figure 3 is an end edge view.

Figure 4 is a transverse sectional view on line P- i of Figure 1. i

Figure 5 is a perspective view of one cor-` ner of the bed spring, morecl'earlyA showing theV construction thereof. l

Referring to the drawings, 1 and 2 designate the lower side and end bars of the bed spring, while 3 and 4 designate the upper side and end bars. The adjacent ends of the upper and lower side and end bars 1, 2, 3 and 4 are riveted or otherwise secured together. In fact, these bars may be welded.

secure the adjacent ends of the upper and j `lower side and end bars together, although they may be otherwise fastened. j l

Interposed between the upper and lower side and end bars of the bed spring are elliptical leaf springs 7 and 8. The ends of the leaves of these elliptical :springs are welded or otherwise securedtogether, as at 9, `there beingstaple rivets connecting the leaves of the' elliptical springs toI the upper and lower side and end bars. Mounted between theupper and lowerl leaves of the elliptical springs are coil springs 10 which are secured in position by the saine staple rivets which secure the leaves of the elliptical springs to the bars.

Longitudinal and transverse bars 11 and 12 are provided. These bars are U-shaped as shown, hence they have depressed portions (which extend substantially the entire width and length of the lower frame) and at their ends upstanding arms 13 and 14 which are guided by the side and end bars of the lower frame, said arms having lateral extensions 15 which are secured to the upper bars of the bed spring frame by means of staple rivets 16. Supported on the depressed portions of the transverse bars 12 at points where they intersect with the longitudinal bars 11 is a plurality of perpendicularly disposed coil springs 17. The lower ends of these 'springs 17 are secured in any suitable inan-v ner, say for instance, by suitable rivet connections or the like to hold the springs in uniform positions.

Connecting the upper transverse end and upper longitudinal side bars of the bed spring traine is a network ot coil springs 19, certain of which are connected to the upper side and end bars of the bed spring traine' through the medium of the eyes in said bars, and others are connected at 20 to he upper ends ot the coil springs which rise troni the transverse intermediate bars. At the ends ot the bed spring, the wires which connect to and extend from the upper ends of the transverse bars are, in turn, connected to rings 2l. These rings are, in turn, connected to other coil springs of the network which, in turn, connect to a plurality oi" siniilar rings. In order to render the network of springs niorc substantial and thereby insure against breaking down of the network and to enable the springs ot the network to properly yield, the rings are connected by intersecting eye-rods 22. Depending from and carried by the lower side barsV of the bed spring` traine are angle plates 23 which are provided for the purpose ot engaging with the bed frame to hold the bed spring in position when in use.

The invention having been set forth, what is claimed is y 1.A A bed spring comprising a bed spring trame consisting of longitudinal side and end upper and lower bars, elliptical springs interposed between the upper and lower bars at the sides and ends ofthe bed spring, coil springs interposed between the upper and lower bars at the corners of the bed spring, transverse and longitudinal intersecting bars connecting the upper side and end bars and having depressed v portions constituting spring supports extending substantially the entire length and width of the bed spring, coil springs supported upon and secured to the depressed portions or" the intersecting longitudinal and transverse bars, and a spring network supported by and connected to the coil springs which rise troni the longitudinal and transverse intersecting bars, said network being, in turn, connected to the upper side and end bars.

2. A bed spring consisting ot' upper and lower trames, elliptical springs interposed between and secured to the side and end bars of both frames, coil springs between the upper and. lower iframes at corners thereof, the upper traine having a depressed portion guided through and below the lower traine, a. plurality of coil springs supported perpendicularly upon and secured to the depressed portion, a network of horizontal coil springs, and connecting rings carried by the upper frame and supported upon the upper ends of the perpendicular coil springs oit the cepressed portion. f

8. A bed spring comprising upper and lower frames, the upper frame having an auxiliary depending frame with a depressed portion consisting of intersecting longitui dinal and transverse bars, the construction and arrangement ot which being such that, when pressure is applied upon the upper traine, the depressed portion of the auxiliary traine guides from the lower traine, the upper traine having a net-work of interconnecting horizontal coil springs and rings, coil springs supported perpendicularly upon the depressed portion of the auxiliary traine and supporting said network of horizontal coil springs and rings, elliptical springs 1nterposed between the upper and lower frames, coil springs between the upper and lower leaves ot the elliptical springs and connected thereto, and coil springs between the upper and lower frames at the corners thereof.

ln testimony whereof she atliXes her signature. Y
