WIRE MATTRESS AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed July 18, 1914. Serial No. 851,693.

To all whom it may concern:

Be it known that I, HERMANN HESS-HON- EGGER, a citizen of the Swiss Confederation,

\ and the like, of which the following is a to the frame of the mattress.

specification.

My invention relates to wlre mattresses, cushions, seats and the like, and a primary object is'to provide an improved elastic wire structure for the same, whose supporting surface principally consists of elastic wire ropes arranged in parallel transverse planes, the ends of the ropes being bent into the form of preferably S-shaped supporting springs which form the elastic edges of the mattressor the like and are firmly attached The elastic transverse ropes are not connected at the level of the surface of'the mattress by any more or less stiff members, so that they can yield elastically and freely in all parts thereof in a vertical and horizontal direction, 6. e. longitudinally of the mattress, and even at the edges.

According to my mvention I support each of the transverse ropes by itself between its elastic supporting ends by stiff struts which are located in the plane of the wire rope at an angle to one another and rest on tensioning wires carried by springs between the 1011-' gitudinal sides of the frame of the mattress, the object of the elastic supporting device being that not only the middle portion of each wire rope shall elastically return to its normal position after being normally loaded,

but that owing to the angular arrangement of the struts the end supporting springs of the transverse ropes forming the edges of the mattress can be slightly adjusted laterally relatively to one another and secured in the adjusted position.

Another object of my invention is to provide improved connecting members which connect the struts on the one hand with the wire ropes and on the other hand with the tensioning devices on which they rest.

To these ends my invention consists in the construction, arrangement and combination of parts described hereinafter and pointed out in the claims.

One illustrative embodiment of my invention is represented by way of example in the accompanying drawing, wherein:

Figure 1 is a vertical cross-section through a preferred form of my improved wire mattress, Fig. 2 being a top plan view of part thereof; Figs. 3 and 4 are like views, respectively, of another form of mattress in which the elastic supporting device for the middle part of the transverse ropes is somewhat modified; Figs. 5 to 7 are two side elevations and a plan view, respectively, of part of the supporting device, while Figs. 8 to 10 are similar views of amodified sup porting device.

In Figs. 1 and 2, the transverse wire ropes b have their ends bent to form S-shaped supporting springs which form the elastic edges of the mattress and are firmly attached to the longitudinal sides a of the frame. These transverse ropes 1) consisting of hard drawn steel wires twisted together are connected. with one another only by readily flexible members, not shown in the drawing, such as cords or chains, which are attached elastically by means of spiral springs to the ends of the frame. Consequently, each of these ropes b can move elastically very freely both vertically and horizontally, i. e. longitudinally of the mattress, along their entire length, whereby a body lying normally on the mattress is prevented as much as possible from resting in a hollow. In order to support these ropes 6 clas tically between their end supports so that the ropes not only will always spring back in the middle to the correct height, but also will always remain extended at the sides of the mattress, e. g. at A in Fig. 1, the struts a which are arranged in the plane of each rope and rest on an elastic tensioning device are arranged at an angle one with the other.

This tensioning device may be made as shown in Figs. 1 and 2. The lower ends of the struts a of each rope areconnected with cured in their adjusted positions through the struts a so that the end S-springs will be located exactly in a rowalong the edges indicated at A. The upper ends of the struts a may be located quite close together in certain cases.

The elastic support or tensioning device shown in Figs. 3 and l differs from that shown in Figs. 1 and 2 only in spiral springs .9 being arranged between the links 0 and the hooks m, while the links 0 of the struts of the same wire rope are connected together by wire ties t.

In order that the wire ropes shall not be prevented from yielding elastically horizontally or vertically by the struts a the latter are connected above with the wire ropes and also below with the tensioning devices by links so that they. can pivot freely about their end supports in the plane of the wire rope and also, within certain limits, relative to this planewhen the wire ropes yield elastically. Further, in order. to prevent all noise owing to jars or friction at these ends of the struts the links at the ends are made so that when the wire ropes yield elastically either vertically or horizontally under the action. of the tensioning devices they always contact at as nearly the same place as possible. The surfaces of contact are at right angles to the supporting device. Pivots producing friction are avoided. These two sheets, namely free and noiseless elastic motion ofthe wire ropes, are obtained by the links of the struts shown in Figs. 5 to 10.

- Fig. 5 shows the strut a; and its links 0 and a in side elevation, the link 0 being shown in section. Fig. 6 is a top plan view showing the link 0 and the parts connected thereto, while Fig. 7 shows another view of the link 0.

The link ohas two end hooks 0 and 0 to one of which the stay is hooked and the spiral spring 8 to the other, a saddle 0 being provided in the middle on which the eye a of the strut a rides. The link a made of malleable cast-iron and firmly clamping the wire rope b in its jaw 0. constitutes an eye into which the. upper eye a of the strut a enters, the latter eye bearing from below against the saddle c off the link 0. It will be readily understood, from Figs. 5and 6 that by means of these links a and 0 the strut a can pivot both in the plane of the wire rope which it' supports and also rela tive to this plane on the saddles c and 0 and that the eyes a? and a of the strut are always held on their saddles c and 0 by the tension of the spirallspring 8, whereby all noise is avoided:

Figs. 8, 9 and lOIshow another form of link 7" which connects the struts a with the stay 79 and the spiral spring 8. Figs. 8' and 9 are views corresponding to Figs. 5 and 6, respectively, and Fig; 10 is anelevation as seen in the direction of the arrow n in Fig.

8. In this modified form of link the saddle W, on which the lower eye (a of the strut rides, is bent downward. V I i The adjustment of the wire-ropes b can be effected in this way that the links a are moved along the ropes to the desired point, after which the jaws c are firmly clamped around the rope. A further slight adjustment may be effected by the staples g in the manner above pointed out. Once adjusted, the ropes are held in their adjusted positions by the non-yielding struts a, resting on a common supporting structure.

I claim 1. A structure, comprising in combination a frame and elastic wire ropes arrangedin parallel transverse planes forming the surface of the structure, the ends of the wire ropes being bent into the form of springs forming the elastic sides of the structure and being firmly attached to the frame, said ropes being able to yield freely in all parts thereof vertically and horizontally, elastic tensioning devices stretched between the sides of the frame, and non-yielding struts arranged at an angle relatively to one another, supporting each rope intermediate its ends, the struts for each rope being carried by a common tensioning device, and means for adjustably securing said tensioning devices to said frame.

2. A structure, comprising in combination.

sides of the frame, and non-yielding struts arranged at an angle relatively to one another, supporting each rope intermediate its ends, links connecting the upper ends of the struts with the ropes, and links connecting the lower ends of the struts for each rope with, a common tensioning device,whereby each strut can pivot atits two ends both in the plane of the wire rope and relative to said plane when the wire rope moves vertically and horizontally, for the purpose of preventing the elasticity of the ropes vertically and horizontally from being im paired by the struts andmeans for adjustably securing said tensioning devices to said frame.
