'A pp1icati0nfi1ed April 22, 1921. seriai No. 463,632.

To all whom it may concern.

Be it known that'l, GH R Es H. GAIL, a citizen of the United States residing at Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certainnew and useful Improvements in Be'dsprings, which the following is a specification.

Simple and eflicient meansfor fastening or securing the ends of short, horizontal, connecting springs to the uppermost coils of the vertically arranged spiral-springsin a bed-spring or similar appliance in such manner that there willbe an entire absence of noise in the use of the structure andin which there is no possibility of the connecting springs becoming displace'd even though the coils of the spiral-springs are not crimped or bent at thepointsvof'attachinent constitutes the substanceof the present invention.

The manner in which these and other desirable objects and aims of the invention are attained in the actual practice of the invention will be readily comprehended by those skilledin this art from. a consideration of preferred embodiments of the invention il in the accompanylng drawing lustrated V v I forming a part of this specification, the detailed descrlptlon of the appliances shown" in such drawing below. I v

In the several views of this drawing the same parts have been supplied with like reference characters. I In the drawing: Figure 1 is a fragmentary plan view of a small portion of a bed-spring or similar structure embodying the present invention; Figure 2 is an "enlarged cross-section on line 2-2 of Figure 1, the parts being viewed as indicated by the arrows being presented herein- I M Figure 3 is a fragment ry plan view of a modified construct on; and

Figure 4 1s a view of the type of construction shown 1n Figure 3 andconstitutes a fragmentary SGCtIQHOIL an enlarged'scale on line ir- 4 0f Figure 3.

Referring to the 'drawing,"it will be per+ ceived that the structure includes the usual longitudinal and transverse rows of vertical, spiral or hour- glass springs 10,10 supported, as is customary, 'at their lower ends-on a suitable framework, not shown, and each having the regular, flat, .top coil or convolution 11,with the common attachment'12 at of spring to its neighbors, all as is clearly spring end loop,

the end of the wire oflwhich the spring is formed.

At their upper ends,these several springs are yieldingly or elastically connected together byhelical-springs '13, 13, four being used to fasten the top coil of'each spiralillustrated,

At each of its opposite'ends, each of such hehcal-springs has an elongated or other appropriately-shaped loop 14 passing over and bearing'on'the wire forming the round top coil of the correspondingupright spiralspring, the terminal portion 15 of the loop wire being bent down outside of such top convolution, whereby there is'no danger of its catching or tearingthe mattress or other cushion adapted to rest on and be'supported bythe spring structure. 1

Each such loop is fastened to the corre-' lated or complementary top'coil on which it rests by a tie-wire 16 extended diametrically, across the spiral-spring, each ofyits ends-being bent to fasten the loop of they corresponding helical-spring in position.

Inasmuch as both ends of such securing wire are similarly bent to perform its holding or binding function, described in detail.

Thewire 16 near the end under consideration is bent somewhat sidewise at 17 in a] more or less oblique direction, then out-f wardly at 18'beneath the top coil wire, then upwardly at 19 at one side ofthehelicalthen acrossthe top of said loop atQO, thence downward at 21' over the other side of the loop, then inward atQQ- under the top coil 11, then up around and over the part 17 at 23 of the same wire, and then down in an inclined directionat; 24 through and in contact'with the end wall of the loop, all as is fully presented in Figures only one will be a land 2.

' In this manner, the helical-spring is bound so securely endwise against the top coil of the upright spring, and its loop is so firmly clamped to the wire forming such coil, that there is no danger of relative slippage ormovemfent of the parts on one another, and hence there is nodangerof the structure squeakin-g or otherwise becoming noisy.

As has beenindicated, the opposite ends of the wire 16 clamp two of the helical springs to the same spiral-spring and in like manner a second cross-w re 25 disposed at clamping wire around the same is omitted.

90 degrees towire ltlandpositione deither above or below the latter wire fastens two other helical connecting springs to the same top convolution of the uprightspring.

It is not absolutely essential, although usually desirable, that the end of the fastening wire be bent around itself at 23, and," accordingly, in Figures 3 and 4c a somewhat modified construction hasb'een presented.

In this case, thehelical-spring and its loops are the same as in the preceding instances, but the end of the fastening wire is somewhat differently shaped.

Such wire 26 is bent sidewise aslant at 27 and then it passes under the top ooilat 28, extending upwardly at 29 outside of such top ring, then it projects horizontally across the top of the loop at3O and then down beyond its other side at 31.

It then continues inwardly at 32 under the top ring, then up at one side at and over the top of one side wire of the loop at It will be seen that this structureis practically or substantially like the other, one except that the bendingof the end of the the main body of In many cases. this latter construction is adequately strong and. obviously employs alesser length of wire.

.In both instances, the ends of the, short helical-springs are very fixedly clamped or tied or attached to the main, load-supporting, vertically-(iisposed spiral-springs, and because of such construction, even though the upper convolutions or rings ofthe spiralsprings are uncrimped at the points of attachment of theshort, horizontal, connecting springs, yet the elementsare so ade quately and firmly secured together that relative movement is impossible 7 under, normal conditions. 7 I

As in somewhat similar constructions, the short helical-springs not only. yieldingly connect the spiral-springs together, but they act in some measureto support thesuperimposedmattress or other cushion, prevent.-.

ing it from unduly sagging between the, upright springs, and the crossed securing wires extended across the upper ends of the vertically-disposed springs, perform a somewhat similar function in supporting the mattress or similar body and preventing it from beoomingunduly depressed in the 00115 or interiorsof the springs.

Cbviously, theinvention is not. confinedto the precise structures detailedfiherein,

since it is of broader scope as indicated by the appended claimsby which itis defined.

Accordingly numerous minor changes may r' be incorporated in the bed-springs shown;

without departing from the fundamental 34,, and then down into the loop helicaI sPring having an end loop bearing on the wire forming said endconvolution,

and means to substantially immovably secure said" loop and convolution together, said loop; and convolution being: uncrimped at their points ofattachment.
