MATTRESS AND BED SPRING.

Specification of Letters Patent.

, Patented Jan. 2, 1912.

To all whom it may concern:

Be it known that I OZELLO R. HUNT, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Mattress and Bed Springs, of which the following is a specification.

.This invention relates to im rovements in mattress and bed springs, an refers more particularly to s rings of that type in wh ch a series of coile springs are connected side bly side over the area of the construction;

springs being generally hour-glass shape Among the salient objects of the present invention are to provide a construction in which the sprin are reliably united in such manner as to orm in effect a continuous surface fabric et nevertheless are capable of being folde or rolled up along any of the lines of juncture of the springs, either longitudinally or transversely of the con struction; to is specially suitable for use inside of a double-faced mattress, by reason of its capability of bending and folding without in- 'ury, by reason of its extreme com ressiility and by reason of the uni ormly smooth surfaces provided for contact with the mattress both above and below; to provide a construction in which the spring units are so united as to provide perfect hinge connections with each other, yet the adjoined wires are so held as to be practically noiseless and ractically incapable of displacement from t eir proper relations to each other; to rovide a construction in which each end of each unit is s anned by a bridge wire which precludes t e forcing of thesmaller coils of the spring axially beyond their limits of elasticity, and therefore prevents the springs from becoming permanently distorted; to provide a construction in which the adjoining springs are provided with interfitting correspondin offsets and insets, the contacting parts .0 which are held in the same plane by clips, thereby affordin a reliable hinge connection, absolutely ocking the springs against rovide a construction which from the following description, reference bein had to the accompanying drawings, m w l0h- Figure 1 is a plan view of a section of springs showing. the relative arrangement and manner in which they are connected; F1%2 is an edge elevation of the part shown in ig. 1; the manner in which the springs may be flexed upon each other in folding up being shown in dotted lines; Fig. 3 is a detailed plan view of one of the springs and fragmentary portions of adjacent connected springs; Fi 4 is a sectional view taken on line H o Fi 3; Fig. 5 is a perspective view of one of t e springs; Fig. 6 is an edge elevation of the spring shown in Fig. 4 compressed.

Describing the preferred embodiment of my invention shown in the drawings, the springs there shown are of the hour-glass type, the opposite sides of the spring structure being recisely identical, although it is obvious t at the invention may be utilized, so far as one surface is concerned, when the springs are of cone-form.

Each spring 1 in the preferred construction shown has its large terminal coils, as 2, 2', provided with four abrupt bonds, as

i

3, 3', 4 and 4, arranged in pairs at ri ht angles to each other, i. e. at 90 apart. he bends 3, 3', are radially outset, as best seen in Fig. 3 while the bends 4, 4', are radially inset, an in connecting up the springs they are, with reference to these insets and outsets, arranged at right angles to each other; the outsets 3, 3', of one spring being arrangedto fit within the

corresponding insets

4, 4, of the adjacent springs. The adjacent internesting or interfittlng portions of the contiguous springs are united and held in the same plane by suitable U-shaped clips 5; these clips being referably formed of sheet metal and provi ed in the ends of the U-arms with registering apertures 6.

To hold the clips in their adjusted positions, 5. e. embracing the interfitted parts of the sprin s, bridge-wires 7 are provided; each spring eing provided at each end with one such bridge wire, the ends of which are looped through both ears of each clip, as shown clearly in the drawin s. As a feature of, some importance in t at it contributes to the noiselessness and reliability of operation of the structure, these brid e wires are of a length slightly less than sulf'b cient to reach from ear to ear of the clips when the coil which it bridges takes circular form primarily given it, so that when the bridge wire is engaged with the clips the end coil of the spring is held under a distinct tension and made very slightly elliptic. The extremities of the bridge wires are bent back toward each other so as to hold the ends of the clips reliably against spreading apart, and inasmuch as the space between the two arms of each cli is just suflicient to accommodate the thic ess of the wires of the coils, it follows that at these hinge connections they are held reliably in the same plane.

Heretofore it has been customary to twist the extreme end of the wire which forms the outermost large coil of the spring around the next smaller coil to provide a suitable finish for the end of the spring, but I prefer to save the expense of so doing, and at the same time provide a somewhat etter construction, by making the end of the large coil terminate just beyond one of the inset or offset portions thereof, as the case may be, so that the clip holds this end, and in order to connect the terminal coil to the next subjacent coil I provide an offset 8 in the spring at the pomt which marks the juncture of the first and second coils; this offset. 8 being so shaped as to be engaged by that part 7 of the bridge wire which passes through the eyes of the clip. Inasmuch as the space inside the clip is just sufficient to accommodate the three wires embraced, it follows that the coils at the point 8 are thus perfectly and reliably united and, that this union is accomplished b the same means which serves to tie toget er the contiguous springs.

By reason of the fact that the bridge wires are individual to the several springs, i. e. they in no instance extend radially outside of the spring to which they pertain, it follows that they do not in the slightest interfere with the folding up of the structure along any of the lines of connection between the springs. It is also obvious that these bridge w1res, one at each end of each string,serve to absolutel confine the smaller inner coils agai st telescoping through the outer .termlnal coils, and thuspreclude the possibility of bending the coils together or past each other far enough to give them a permanent set.

Inasmuch as the brid e wires are alternately arranged at rig t angles to each other in the successive s rings of any givenrow, and inasmuch as the terminal coils of the springs are capable of being distorted slightly, z. e. sprung out of their normal sha e, in a direction at right angles to the bri ge wires, it follows that the surface of the spring structure is slightly elastic; the aggregateelasticity of a glven row extending the full length or width of the bed being substantial. This is a feature of much importance when the spring structure is used inside or beneath a thin mattress, because each individual part of the sprin structure will yield to accommodate the body. The importance of making the bridge wires the several the pliability of the spring structure and yet does not seriously sacrifice its strength.

While I have herein shown and described what I deem to be the best embodiment of my invention, nevertheless modifications may be made without de arting from the spirit thereof. For exampYe, it will be noted that the bends are not internested with corresponding bends in the ad 'acent wires yet they are nevertheless reliably confined by the clips and bridge wires, and this at once suggests that it is not absolutely essential that the other wires be actually internested, z. e. bent in such manner as to interfit, in order that they be held reliably in proper relation, although this is the preferred construction. Accordingly the claims hereto appended are to be construed broadly, except in so far as they are couched in specific terms.

I claim as my invention:

In a furniture spring structure, a series of coiled s rings arranged side by" side with their terminal lar e coils in juxtaposition, the peripheral portions of said terminal large coils being provided with interfittin abrupt radial deflections or bends, where y they are locked against circumferential movement relatively to each other, and tying devices embracing said inter-fitting ortions, holding them in the same plane an holding them against radial separating movement.

Ina furniture spring structure, a row of coiled sprin arranged with their terminal large cm s in juxtaposition, the peripheral juxtaposed portions of said terminal large coils bein provided with closely fittinlg internesting fiends lying in the plane of t e surface of the spring structure, whereby said springs are locked against circumferential movement out of alinement with each other in the row, clips embracin said internested eripheral portions an holding them in the same plane with each other, and bridge members extendi diametrically across every alternate spnng in the row and connecting the clips of that structure, a set spring.

3. n a furniture sprin in rows in two of coiled springs arrange directions at right angles to each other and with the peripheral portions of their large terminal coils in juxtaposition, the juxtaposed peripheral portions of said terminal large coils being provided with closely fit- 13o ting internested abrupt shoulders or bends, nate springs in each row and in each direchinging devices embracin and tilengc1S toi tion being arranged at right angles to each gether the juxtaposedshou ders or other.
