BED OR COUCH BOTTOM.

SPECIFIGATION forming part of Letters Patent No. 747,176, dated December 15, 1903. Application filed June 18, 1903. Serial No. 162,006. (No model.)

lib all whom, it may concern:

Be it known that I, JOHN HOEY, a citizen of the United States, residingin the city and county of San Francisco, State of California, have invented an Improvement in Bed or Couch Bottoms; and I hereby declare the following to be a full, clear, and exact descrip tion of the same.

My invention relates to improvements in bed and couch bottoms of that class in which a woven wire or equivalent support for the upper mattressis attached to a framework, which framework is supported upon the bedstead.

My invention consists of parts, constructions, and combinations hereinafter described.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a partial plan showing the fabric attachment. Fig. 2 is a transverse section of same. Fig. 3 is a perspective view of strengthening-bar and an adjustable frame.

Bed and couch bottoms are largely made by stretching a woven-wire or equivalent fabric across a rigid supportingframe. The difficulty in the employment of such fabric is the tendency of the central portion to be unduly depressed and the nnsuppprted sides or edges of the fabric to be drawn toward each other by continual use. It is the object of my invention to stiffen and strengthen such fabric and to maintain the edges in their proper position and to prevent the undue depression of the bearingsurface.

As shown in the drawings.,A represents the side, and B the end rails, of a mattress or couch frame bolted together at the angles and constructed in any suitable or desired manner for the support of the woven-wire fabric 2, which 'is here shown as secured to the end bars and extending without attachment from one end to the other. In order to equalize and distribute the depressing action of the weight appliedto the surface of this fabric and also to maintain the fabric in its full transverse width and to prevent its being contracted or the edges drawn inwardly, I have shown the metalbars 3, which are in the form of elastic bars, each of which has upward or downward bent curves or loops 4 at short intervals. These bars extend entirely across from one side of the fabric to the other and may be applied either above or below. In the present case I have shown the bars lyingupon the upper surface of the fabric and the loops 4 projecting downwardly between the meshes of the fabric.

By means of links or equivalent attachments5 of any desired description passing through the loops below the fabric they are prevented from being drawn out and the bars are maintained lying flat upon the surface of the fabric. The ends of the bars are in like manner connected with the outer edges of the fabric, and as the bars are continuous from one side to the-other it will be manifest that the edges of the fabric will be prevented from drawing or being pressed inwardly.

The bars are so elastic that they will be depressed at any point in unison with the depression of the fabric itself, and by reason of the downwardly-curved loops and the short distance between the loops this elasticity of the bars becomes almost the same as that of the fabric itself. I have found that by extending one or more of these bars across the fabric the latter is greatly strengthened, especially in the central portion, which is subject to the greatest depression by reason of its distance from the end supports.

It will be understood that my invention is equally applicable to couch or bed bottoms in which one end of the fabric is secured to a tension-adjusting bar movable with relation to the main frame, as shown in Fig. 8.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination in a bed or couch bottom of a rigid frame, a fabric stretched from end to end thereof, transverse elastic bars having their ends secured to the fabric, and attachments between the bars and the fabric at points intermediate of the ends.

2. The combination in a bed or couch bottom of a rigid frame,an elasticfabric stretched between the ends thereof, elastic metal bars having bent loops at intervals extending through the fabric, means for maintaining the bars in position upon the fabric and conand means for securing the bars to the fabric [0 nections between the ends of the bars and the at intervals between the ends.
