Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed April 28, 1911. Serial No. 623,956.

b all whom it may concern:

Be it known that 1, Jones RonvER, of the city of New York, county of Queens, and State of New York, have invented a new and useful Improvement in Bed-Springs, of which the following is a full, clear, and exact description.

My invention relates to improvements in bed springs, and the object of my invention is to produce a simple, inexpensive, and exceedingly resilient and easy bed spring which can be easily applied to an ordinary bed and is easily removed, which is adapted to have a perfectly flat and yet resilient surface, and further to provide a bed spring in which the surface is formed of longitudinal parallel inelastic bands which at the end portions are each connected with spiral springs so as to pull lengthwise on said springs, thus giving resiliency to the bands, and also to provide spring bolsters which are adapted to l e beneath the bands of the main springs and which by being movable can be made to support the main surface of the bed spring at any desired point.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a plan view of a pair of bed springs embodying my invention, the same being shown in position on a bedstead. Fig. 2 is a broken enlarged detail plan of one end portion of the bed spring. Fig. 3 is a broken inverted plan of the structure shown in Fig. 2. Fig. 1 is a broken side elevation of the spring as applied to a bedstead. Fig. 5 is a detail side elevation of one of the spring 1001- sters. Fig. 6 is a detail sectional view showing one of the end supports for the spring, and Fig. 7 is a detail cross section on the line 77 of Fig. 2.

The bed spring has side rails 10, which are preferably of angle iron, to form a convenient support for the bolsters hereinafter referred to, and the side rails are connected by cross pieces 11 near the ends and by cross rods 12, any necessary number of cross pieces and rods being used. At the ends of the bed spring and a little above the bed portion thereof are transverse shafts 13, each being provided with a series of rollers 14 which are spaced apart and grooved slightly so that the bands 18 hereinafter referred to may run smoothly on them and fit snugly in the grooves so as to leave the top surface flush with the surface of the rollers. Each shaft 13 is supported in a series of braces 15 which are in turn mounted on the cross rods 12 and 16 which connect the side rails of the bed spring near the ends. Each end of each band 18 is connected with a spiral spring 17 which is also attached to the cross rods 16. The rollers lt are fitted to run smoothly and, it will be seen that when tension is applied to the bands 18, as by a person lying on the bed spring, the tendency to sag is resisted by the tension of the spiral springs 17, while a very easy bed is afforded by the longitudinal resilience of the springs 17 It will also be noticed that each band 18 is an independent unit and that the bed is therefore very comfortable to lie on. It will further be observed that by this construction the tendency to produce a permanent depression in one part of the bed is obviated, and further that by this construction two bed springs can easily be applied to a double bed as shown in Fig. 1, and the depression of one part of the bed spring will not affect the other part, as is the case where a full woven surface on a sin-' gle spring bed is used.

The arrangement just described produces a very comfortable bed, but some people, either through excessive weight or for other reasons, prefer a bed that will not be so resilient, and to meet these requirements Iprovide bolsters l9 and 19 which are themselves resilient but which can be slipped along underneath the bands 18 so as to stiffen these, and at any necessary point. Each bolster is provided with top and bottom rails 20 and 21 which are spaced apart by the vertically arranged helical springs 22, and the bottom of each bolster is provided with ledges 23 adapted to rest in and run along the angle iron rails 10 of the bed spring. The top and bottom rails of the bolster are also connected by guide rods 24 which are secured to the top 20 and slide freely through the bottom portion of the bolster. At the right hand in Fig. 1 I have shown the bolster with two top rails 20 and a corresponding double set of springs 22, while at the left hand in Fig. 1 this arrangement is shown in triplicate, but obviously a greater or less number of banks of springs 22 can be used as desired.

Any suitable bedstead, as for instance the bedstead 25, can be used in connection with the bed spring, and I prefer to have the bedstead provided at the ends with ledges 26 preferably in the form of angle irons, so that the bed spring ends may be laid on these ledges, and by making the bed springs in single bed sizes and using two of them on one double bed as shown, the springs are easily handled and can be placed on or removed from a bedstead without injury to either the bed springs or the bedstead. Attention is called to the fact that the parallel bands 18 can be rigidly supported at one end if desired, and a cheaper bed spring produced, as the resiliency of the springs 17 at one end will answer the purpose very well, but I prefer to make the bed spring double ended as shown.

It will be understood from the foregoing description that the particular means for supporting the ends of the bands 18 of the bed springs can be departed from without affecting the invention, but the general arrangement of the bands and the mainte nance of their tension by longitudinally arranged spiral springs, should be preserved.

I claim 1. A bed spring comprising a base or frame, a series of parallel inelastic bands forming the bed spring surface, a separate rotatable guide or support for each band near its ends, and longitudinally expansible springs secured to the ends of the bands and to the frame of the bed spring.

2. A bed spring comprising a frame, a transverse shaft supported at each end of the frame, a series of rollers supported on the shafts, inelastic bands extending lengthwise of the frame and passing over the rollers, and a transverse support for the bands, said support being slidable longitudinally on the frame and having its top and bottom portions spaced apart by springs.

8. A bed spring comprising a base or frame, transverse shafts at the end portions of the frame, braces spaced apart to support the shaft, a series of rollers on each shaft, inelastic bands extending lengthwise of the frame and passing over the said rollers, and a pair of spiral springs for each band, said springs being attached to the ends of the band and to an adjacent support on the frame.
