FABRIC BED-BOTTOM.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application led January 15, 1919. Serial No. 271,204.

To all whom t may concern:

Be it known that I, JOSEPH CIPOLLA, a subject of the King of Italy, but now residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Fabric Bed-Bottoms, of which the following is a specification.

My invention relates to a wire fabric bed bottom interlaced in forming the same and surrounding therefor having the end members connected to the side members by interposed coiled tensioning springs and in between with straining diagonally disposed springs for maintainlng the bed bottom throughout under a uniform tension for greater comfort and for the avoidance of sagging in portions under undue pressure exerted in one portion tendin to distort the surface of the bottom, which 1s compensated for or taken up by other portions through adjustment of members of the framing in respect to each other, under the load or strain.

The principal object of my invention, as thus defined, and in furtherance of such, as features thereof, consists of a fabric wire bed bottom constructively arranged in substantially the manner hereinafter described and claimed.

The nature, scope and characteristic features of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof; in which- Figure 1, is a top or plan view of a fabric wire bed bottom, embodying the essential main features of the same.

Fig. 2 is a transverse sectional view on the line m, of Fig. 1; and

Fig. 3 is a fragmentary sectioned end elevation of one of the side and of the end members of the supporting framing and the connecting coiled springs and straining tensioning coil springs of the present invention, as an embodiment thereof.

Referring to the drawings e, is the bed bottom comprising wire springs interlaced together to form the surface of the fabricated bottom and which throughout is of the character as illustrated, in Figs. 1 and 2.

The supporting framing o, consists of preferably thin metal end members b and b1, and similar side members b2 and b3.

These members, respectively, are coupled to each other by means of interposed coiled horizontally arranged springs c1 and c2, and in between the same a diagonally disposed coiled or other type of spring o8, and which is designated as the tensional or straining spring of each series in connection with the said end and side members of the said supporting-framing c, adjacent to the respective four corners of the bed-bottom. The fabricated wire bed-bottom is fixed to the side and end members of the said supportingframing, in preferably, the manner as illustrated in Fig. 1, so as thereby to stabilize the whole through the arrangement of the interposed horizontal and diagonal springs c1, 02 and c3, in direct connection with the said end and side members of the framing, but not with the bed-bottom proper; and which arrangement constitutes the means, whereby pressure either normal or abnormal exerted o'n the bed-bottom in any portion is compensated for by the said side and end member springs at the respective points of connection for taking up the same under either direct or indirect strain; and hence there is provided a bed-bottom of a decidedly comfortable character as practice has demonstrated, and a bottom aswell that can be maintained in a highly sanitary condition, at all times for use.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is The combination, in a bed-bottom, of end strips, a fabric extending to the end-strips and interlaced therewith, broad side strips shorter than the fabric and interlaced therewith, the side strips connected at their ends to the ends of the end-strips by helicals, some extending longitudinally and some diagonally to form spring equalizing and straining means for the fabric, for maintaining uniform positioning tension of the same, against sagging under normal and abnormal pressures.

In witness whereof, I have hereunto set my signature in the presence of two subscribing witnesses.

JUSEPH CIPOLLA.
