BED-SPRING.

Specification of Letters Patent. Patented Apr; 16, 1918.,

Application filed March 3, 1915. Serial No. 11,670.

To all whom it may concern:

Be it known that 1, WILLIAM LEWIS, a citizen of the United States, and resident of Utica, in the county of Oneida, in the State of New York, have invented new and useful Improvements in Bed-Springs, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in spring beds in which the mattress, whether of woven wire or upholstering, is supported upon a system of helical springs resting on a suitable supporting frame, and while the main object is to provide this class of spring beds with marginal upstanding rails for retaining the upholstered mattress in place against lateral or endwise displacement and to sustain the edges of such mattress against fiattening or rolling downward, the specific object is to support the greater portions of such rails directly upon the upper ends of the coil springs so that they may yield under pressure independently of the frame, but the upper ends of the springs are held in definite relation to each other.

Another object is to make these confining rails of straight and relatively heavy wire as distinguished from coiled wire so as to afford greater resistance to the spreading out or displacement of the mattress laterally, and at the same time permitting them to yield vertically, as for example under the pressure of a person sitting on the edge of the bed.

Other objects and uses relating to specific parts of the spring bed will be brought out in the following description.

In the drawings- Figure 1 is a top plan, partly broken away, of a spring bed in which the upholstered mattress rests directly upon the upper ends of the system of helical springs.

Fig. 2 is an end view of the same'spring bed partly broken away.

Figs. 3 and 4 are enlarged vertical sectional views, taken, respectively, on lines 33, Fig. 2 and H, Fig. 1.

Fig. 5 is an inner face View, partly in section, of the central upper portion of one side of the spring bed, showing the manner of supporting the guard rail on the upper ends of the coil springs.

Fig. 6 is a top plan, partly broken away,

rail is attached being shown in section.

In the spring bed shown in Figs. 1 to 5, inclusive, the system of'helical springs as -l and 2 are mounted upon a suitable supporting frame 3 and the upper ends of the marginal series are bound or held in fixed relation by a superposed mar- .ginal frame 4l, tied to the upper ends of the springs of the marginal series by suitable tie-pieces 5.

The upper ends or convolutions of the springs 2 of the marginal series are provided with eXtensions -6 arched upwardly and constituting resilient guards rising from the outer edges thereof some distance above the horizontal plane of the frame -t and having at their highest points tie-pieoes 7- for receiving and supporting a marginal guard rail -8- which extends along both sides and across one end and part way across, the opposite end or head of the frame 4- in a plane substantially parallel with, but some distance above the same for the purpose of retaining an upholstered mattress on the upper ends of the springs against lateral or endwise displacement, and at the same time sustaining the edges of such mattress against matting, flattening or rolling down.

It will be noted, however, that by supporting this guard rail directly upon the arched extensions 6 of'the marginal series of springs and independently of the underlying frame which ties the upper ends of said springs to each other, it permits a limited vertical yielding movement of the guard rail, and particularlyv the longitudinal sides thereof where pressure is most often brought to bear by persons sitting upon the edge of the mattress, and by making this guard rail of a straight piece of wire as distinguished from coiled wire, it is evident that it is less liable to be stretched.

' 1 1 and guard: rail against lateral or endwi'se out of shape and is, therefore, more permanent and durable in the performance of its function of holding the mattress against shifting on the springs.

This particular form of guard rail. is preferably made of a single piece of wire haying its ends extended from the opposite sides part way across one end, as the head end, of the bed to form end brace-rails -l0 which are depressed to the plane of the frame and are secured thereto by clips 9 the remaining portions of the guard rail extending along the sides and around the foot of the bed. 7 I v This yielding action of the guard rail is mademore apparent upon reference to Fig. 5, in which'iit will be seen'that the upwardly arched portions 6 of the helical springs 2 rise from portions'of the" underlying convolutions of said springs some distance from the points of attachment of said underlying convolutions to the marginal frame 4, thus not only producing the resiliency afforded by the arches 6', but also that aiforded by the portions of the underlying convolutions of the spring along the sides of the bed at opposite sides of the cli" theadjacent sides of the upper ends of the helical side springs -2- at th ir junction with the spring arches -6 being sufliciently close to be tied together by tiepieces 10.t0 additionally hold the upper ends of said helical springs in definite rela tion to each other, which together with the 7-, serve to hold the movement. 7 a a a The ends of this guard rail are preferably bent downwardly at 11- Fig. 3:, to prevent their accidental displacement from the 'fi 'w f'a Figs. 6, 7 and 8, I have shown an iron frame -3- and opposite sets of helical springs '2". mounted on the longitudinal sides of the frame 3- and rising there- 'ti'e frame.

A woven wire mattress -a is stretched across and upon the upper faces of the tiefranies l and fastened at its ends to angle plates 12 on the opposite ends of the main supporting frame 3.

The springs -2 of each set are also provided with upwardly arched extensions iprojecting some distance abovethe horizontal plane of the tie-frame 4''- and woven wire mattress -a as shown more clearly in Fig. 7 for supporting at their highest points opposite lengthwise upon the upper faces of the end plates -I2 and having their terminal ends passed through said plates and fastened thereto by nuts or shoulders -1flto firmly hold the'rails in operative position.

Itwill be observed, however, that'theend's of the spring. arches -'G are united directlyf to the upper ends of the helical springs '2" some distance from and at opposite sides of the clips -5 so as to allow the guard rail 8 to yield dofWn- V.

The important feature, therefore, of my invention is the supporting of the guard rails directlyupon' the upper ends of the outer helical springs so as' to yield independently of the frame which ties the upper 'n r as described for the guard rail -8-, in
