To on whom it nay concern.

Be it known that I, HENRY RroHARDsoN, a subject of the King of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed-Bottom Fabrics, of

which the following is a specification.

My invention relates to bed-bottom fabrics, and pertains more especially to that class or type of fabrics which are made up of interconnected bent wire units. Numerous bed-bottom fabrics of this general. type have been devised and used, in most of which, so

far as I am aware, the units are so disposed teract such tendency.

A leading object of my invention is to produce a bed-bottom fabric wherein the bent wire units shall be so disposed when connecttension, and this object I accomplish through the employment of wire units so bent as to present open and closed ends at the opposite ends of the unit, respectively, these units be ing arranged in a series of longitudinal rows or strands wherein adjacent units are inversely disposed,so that their closed ends are adjacent to each other and their open ends are adjacent to each other, the closed ends being further connected by an intermediate longitudinally-rigid link, while their open ends may be connected either by direct interhooking or by the interposition of connecting-links of ring or other form. The unit in its preferred form has symmetrical longitudinal sides united integrally at one end to form a narrow closed end for the unit, while their opposite ends diverge, producing a wide open end of the unit.

In the accompanyin drawings I' have illustrated two praotica forms of fabric in which my invention may be embodied.

Referring to the drawings, Figure 1 is a plan view of a portion of a bed-frame, showing my improved fabric applied thereto. Fig. 2 is an edge view of the same. Fig. 3 is a view similar to Fig. 1, but showing a slight modification in the manner and means of connecting the open ends of the units; and Fig. 4 is an edge view of Fig. 3.

Referring to the drawings, 5 may designatethe siderail, and 6 the end rail; of an ordinary bed-frame, said rails being preferably in the form of angle bars rigidly united at the corners by bolts -7 and nuts 8.

The fabric of the bed-bottom. is composed, preferably, of a series of bent wire units, that are disposed in straight longitudinal and transverse rows or strands. While the particular form of the bent Wire unit herein shown is not of the essence of the present invention, yet within the invention the unit is characterized by a wire so bent as to present a substantially symmetrical pair of sides, that converge and meet at one end in a closed end of thennit, while at the opposite end of the unit said sides are divergent, thus pro ducing a wide open end of the unit.

In the drawings I have designated the main portions of the sides of the units by 9, the closed end, which is preferably bent to present an eye, being designatedby 10. The free ends of the sides 9 at the open end of the unit are preferably doubled back to produce hooks, (designated by 11, Fig- 2.) ed as to substantially eliminate this diagonal 4 As regards the arrangement of the units it will be observed that in each longitudinal strand adjacent units are inversely disposed-that is to say, thenarrow closed ends are adjacent to each other and the wide open ends are adjacent to each other. The units of the several longitudinal strands are con nected at their closed ends through the interposition of longitudinally-rigid links, which preferably take the form, herein shown, of straight wires 12, having. hookedends -13, that engage the eyes 10 of the units. The adjacent open ends of the units are preferably connected through the interposition of links 13 of ring shape, which are engaged by the hooks 11 on the open ends .of the units, said rings serving to transversely unite the several longitudinal strands at suitable intervals.

On each longitudinal side of the fabric in order to produce a straight edge I employ a longitudinal strand made up of half units, (designated as an entirety by 14,) said half units being connected endwise by the straight wire links 12 and links 13, the same as the entire units.

To afford increased elasticity, the fabric at either or both ends is preferably connected with the end rail 6 through the interposition of helical springs .15, having at their outer intervals by means of transverse. clips 19,.

which may be located at any convenient or preferred point. or points, but which preferably are locatedadjacent to the interhooked ends of the units, as shown.

From the foregoing it will be seen that my invention provides a bed-bottom fabric capable of b61119 easil and uickl assembled y y 7 presenting a neat and attractive appearance,

and so organized as to resist superimposed strains along longitudinal and transverse lines, avoiding diagonal or oblique tension, with the stiffness and deformation resultant therefrom.

I claini- 1.. Abedbottom fabric of the class described, comprising a plurality of longitudinal rows or strands each including a series of endwise-connected. bent wire units, each of said units having a narrow closed and a wideopen end, adjacent units in each row being inversely disposed and having their closed ends connected by an intermediate longitudinally-rigid link, substantially as described.

2. A bed-bottom fabric of the class described, comprising a plurality of longitudi nal rows or strands each including a series of endwise-connected bent wire units, each of said units having a narrow closed and a wide open end, adjacent units in each row being inversely disposed and having their closed ends connected by" an intermediate straight link interhooked therewith, substantially as described.

3. A bed-bottom fabric of the class described, comprising a plurality of longitudinal rows or strands each including a series of endwise-connected bent wire units, each of said units having a narrow closed end formed with an eye and a wide open end, adjacent units in each row being inversely disposed and having their eyes connected by an interinedate longitudinally-rigid link, substantially as described.

4. A-bed-bottorn fabric of the class described, comprising a plurality of longitudinal rows or strands each including a series of endwise-connected bent wire units, each of said unit-s having a narrow closed end formed with an eye and a wide open end, adjacent units in each row being inversely disposed and having their eyes connected by an intermediate straight wire link interhooked therewith, substantially as. described.

5. A bed-bottom fabric of the class described. comprising a plurality of longitudinal rows or strands of bent wire units, each of said units having a narrow closed and a Wide open end, adjacent units in each rowbeing inversely disposed, longitudinally-rigid links connecting the closed ends of adjacent units, and rigid links connecting the open ends of adjacent units, substantially as described. Y

6. A bed-bottom fabric of the class described, comprising a plurality of longitudinal rows or strands of bent wire units, each of said units having a narrow closed end and a Wide open end terminating in hooks, adj acent units in each row being inversely disposed, straight wire links having hooked ends engaging and connecting the closed ends of adjacent units, and rings engaged by and connecting the open hooked ends of adjacent units, said rings also transversely uniting the longitudinal rows or strands, substantially as described.

7. A bed-bottom fabric of the class described, comprising a lurality of longitudinal rows or strands o' bent wire units each having an open and a closed end, adjacent units in each row being inversely disposed with their open ends connected together and their closed ends united through an intermediate longitudinally-rigid link, substantially as described.
