Specification of Letters Patent.

Patented Apizfi, 1920.

Application filed April 6, 1917. Serial No. 160,214.

To all whom it may concern:

Be it known that I, CLARENCE WV. PIPER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Bed-Spring Fabrics, of which the following is a specification.

This invention relates to certain new and useful improvements in borders for bed springs and the provision of a novel form of wire fabric, the primary object being to pro vide an improved form of bed-bottom which is light and durable, of economical construc-. tion and very neat in appearance.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.

In the drawing, 7 I

Figure 1 is a detail plan v ew of a bed bottom constructed in accordance with my invention; Fig. 2 is a side view broken away, Fig. 3 is a sectional detail of one means of connecting the fabric to the mat- V tress frame; Fig. at is a detail showing the manner of constructing the fabric; Figs. 5 and 6 are different forms of the clip spacing means employed; and Figs. 7 and 8 show modified arrangements of the border with respect to the fabric.-

Like numerals of reference refer to like parts in'the several figures of the drawing.

Referring to the drawing 2 represents the sidebars, and 3 and 4 the foot and head bars, respectively, of a mattress frame which, it will be understood, may be of any preferred size, shape and configuration, though as shown, these parts are of angle iron secured at their points of intersection by means of bolts or rivets 5.

At each of its longitudinal edges, the improved wire fabric employed is providedwith a border consisting of a pair of spaced built-up wires, each of which is bent intermediate its length to form

strands

6 and 7 in parallel proximity to one anoth r and has its ends rigidly fastened together by means of a clamp 8 to be hereinafter more specificallv referred to. Each of the pairs of strands thus formed is secured at intervals to its adjacent pair through the medium of a plurality of clips consisting of wires 9 of suitable length, each of the ends of which is caused to encircle and tightly clamp a pair of the strands as'clearly shown in Fig. 5

. strands within the mattress frame.

and in this way retain the individual pairs of strands. distanced apart. More particularly, the .wire 9 forming the clip is bent at points removed, the ends thereof to form shoulders 9 against which the fabric strandsabut and is thence continued around the strand so that the ends of the wire rest against the shoulder as shown- By this construction of clip, it has been found that there is less tendency 'of the strands being unintentionally forced" out of the loop formed by the encirclingpart of the wire.

In Fig. 4: is shown a detail of the manner in which the

strands

6 and 7 of my improved border are constructed. As illustrated, these strands consist of a wire 10 of suitable size and continuous length forming a core about which is tightly and spirally wound or wrapped a plurality of small flexible wires;

11 whereby a finished construction is formed that is exceedinglydurable and which at the same time presents a neat appearance andv is light in weight.

As above pointed out, a continuous wire of this type is bent, midway of. its length to form the

strands

6 and 7, a helical spring 12 being utilized for securingthe looped end 13 of the wire to the head hard of the frame. At the other extremity, the ends of the wire are secured rigidly together by means of the clamping device 8, which is double crimped as shown at 8, the holding effect of which V is augmented by the employment of the somewhat yieldable surfacing formed by the spirally wrapped wires 11. A coil spring 15 is secured at one end tothe foot bar 3 and is provided at its other end with a hook 1.6 which is passed between the

strands

6 and 7, as shown in Fig. 3 to properly secure the As further shown in this figure, the clamped ends of the wire are disposed inside the sprin 15 so as to obviate any possibility of bed clothing engaging being damaged by contact .therewit The space intermediatethe border edges may be occupied by. fabric of any suitable,

construction, but as shown it consists of continuous wires each bent midway of its ends c to form

parallel strands

17 and 18 spaced apart by clips 19,'see Fig. 6, very similar in construction to the cli '9 shown in Fi 5. It will be noted that theseclips 19 not 7 only space the strands of each pair apart, J

llO 3 but they are also used in alternate arrange ment tocsecure the adjacent strands of different pairs together. It will also be noted. that the borders, though positioned in proximity to the strand of the next adjacent pair,

are not connected by means of clips or otherwise to such strand as it has been found in practice to be unnecessary due to the lateral rigidity of the borders formed in the manner heretofore described.

In Fig. 7 is shown a modified construction of fabric wherein the strand 18 of the outermost portion of the fabric overlies to some extent the adjacent strand 7 of the border and in this way tendency of the mattress or bed clothing towork its way between the border and the fabric is eliminated. .Furthermore when excessive pressure is brought to bear upon the border, it will be under.- stood that a degree of lateral movement thereof is permitted without interfering with the substantial continuity of the bed bottom.

In Fig. 8 the border is shown as con structed of asingle pair of

strands

6 and 7 spaced at intervals by means of clips similar to those 19, the ends of which are bent upwardly around the strands of the border; while the

strands

17 and 18 of the fabric are spaced by means of clips substantially identical in all respects with those 19 except that their ends are bent downwardly around the strands. By this means, the strand 18 of the outermost portion of the fabric is adapted to overlie and in effect nest between the

strands

6 and 7 of the adjacent border.

In neither the preferred form nor the modifications shown,is the fabric attached or in any wise secured to the border as in this manner a greater give or yield is. ob

tained without sacrificing the comfort of the user. Y p

In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth 1 within the scope of the following claim.

Having described my invention, what I claim as new and desire to protect by Let- CLARENCE W. PIPER.
