SPECIFICATION formingpart of Letters Patent No. 758,008, dated April 19, 1904.

Application filed J1me 1903- To ctZZ whom it may concern:

Be it known that I, PARKER D. HEATHER, a citizen of the United States, residing at Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Cots, of which the following is a specification.

This invention relates to furniture having a spring-support, the purpose being to provide novel means for sustaining the fabric and to prevent careening or swaying of the springs when subjected to perpendicular pressure or strain about at a right angle to the plane of the support.

The invention is particularly designed for cots, couches, chairs, and like articles of furniture intended to support the person in either a sitting or recumbent position.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and draw ings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical central longitudinal section of a cot illustrating the application of the invention. Fig. 2 is a transverse section about on the lineX X of Fig. 1, the parts being on a larger scale and the intermediate portion broken away. Fig. 3 is a detail perspective view showing more clearly the supporting and guiding means for the springs and covering. Fig. 4 is a detail perspective view of the component parts of the guide, the same being separated.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The relatively fixed section of the cot or like article is indicated at 1 and the adjustable section at 2, the latter being hinged to the former. Each section comprises a frame 3, supporting-springs 4, and a covering 5, the

laced and confine the lower coils of the springs 4, as shown most clearly in Fig. 4. Strips or slats 7 rest upon the springs 4 and may be attached thereto and are adapted to sustain the covering or fabric 5 at desired points. Clampstrips 8 are secured to the slats 7 by suitable fastenings and confine the fabric 5 thereto.

The strips 7 act as stays and equalize the pressure or load upon the springs, thereby preventing undue straining of the fabric 5 when loaded at one point.

An essential feature ofthe invention is to insure movement of the slats or strips 7 in straight lines and in a direction at a right angle to the plane of the fabric 5. In order to attain this object, guides of novel construction are interposed between the parts 7 and elements of the frame 3 and cooperate th erewith. The guide means consists, essentially, of a socket-plate 9 and a ribbed bracket 10. The socket-plate 9 is provided with parallel flanges 11, curved toward each other at their outer ends and inclosing guide-space 12 to receive the rib 13 at the vertical edge of the bracket 10, said rib 13 having a head 14 at its lower end to limit the upward movement of the bracket 10 with reference to the socket-plate 9. The parts 9 and 10 are firmly attached to the respective parts 3 and 7 by any suitable fastening means. These parts 9 and 10 may be constructed in any commercial manner, either by being cast, drop-forged, or struck up from sheet metal.

In the adjustment of the parts the upper ends of the springs 4 project above the plane of the upper edge of the frame 3. Hence the fabric 5 normally occupies a position above the plane of frame 3, and its end portions are drawn downward and secured to opposite bars of the frame, as shown most clearly in Fig. 1.

nected with and upheld by said frame, a sup- Any Weight or strain coming at a right angle upon the fabric will cause the springs to contract in a direction at a right angle to the plane of said fabric, this being due to the guide devices 9 and 10 applied in the manner stated. It will thus be seen that the full benefit of the tension of the springs is obtained, and said port sustainedby said springs, and means for directing the coil-springs when contracting and expanding, said means consisting of a socket-plate havingparallel flanges curved toward each other at their outer edges and a bracket having a rib slidably mounted in the space formed between the flanges of the socketplate and having'a head at one end of the rib and an arm at the opposite end to positively limit the movements of the bracket in each direction, said slidable bracket having the aforesaid support attached thereto, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
