Specification of Letters Patent.

Application filed October 20, 1914. Serial No. 867.570.

To all whom t may concern: Y

Be it known that I, AUGUST J. KREUZ- KAMP, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bed- Springs, of which the following is a specication.

This invention relates to bed springs, more particularly to that form thereof known as spiral bed springs, in which the spring consists of suitable supporting means and spiral springs carried thereby for supporting the ordinary'stufed mattress, the object of the invention being 'to provide an improved spring of this kind.

I-Ieretofore it has been found practicable to provide only flat bed springs, that is springs in which the bottomis formed of a fabric of some kind, with side-guards, and although it has been highly desirable to make spiral bed .springs with side-guards this has not been found practicable for various reasons, among others the diiiiculty of attaching and the difficulty of maintaining such side-guards in shape and position, and therefore I believe that Iam the first to provide a side-guard spiral bed spring in which the guards will prevent the shifting, spreading and flattening of a stuffed mattress and maintain it in its boxlike shape, and therefore the object of the present improvement is the provision of a bed spring of the class described having side-guards expensively but practically applied, and which structure is durable and practicable so that all the advantages of the ordinary sideguard flat spring are obtained in the spiral form of bed spring.

In the drawings accompanying and forming part of this specification, Figure 1 is a perspective view of this improved springt; Fig. 2 is a side view thereof; and Fig. 3 is a detail view of the guard partly broken away. VSimilar characters of reference indicate corresponding partsy throughout the several figures of the drawings.

The spiral spring supporting means may consist of any suitable. framework 2. In the form shown it consists of a pair of lon- 'gituclinal extending bars 3 shown as of angle which are iniron form connected crosswise at their ends by suitable angle iron bars 4, and by a series of intermediate bars. Supported by these bars are a series of spiral springs 5 of any suitable form. The outer row of springs at each side of the bed spring is shown connected by a longitudinally extending wire or rod 6 inturned at its ends as at 7 and connected along the inner sides of certain of the springs. The angle iron bars t are bent upward attheir ends as at 8 so as to extend above the spiral springs va predetermined distance, thus forming guard supporting means or brackets 8', and these brackets are connected by braces 9 with the spring supporting means, and the upturned portions are also suitably braced. In the present instance the lower ends of the braces 9 at each side of the. bed spring are connected with the outer longitudinal extending bar. Stretched between the upper ends of the `supporting brackets .is a Asuitable side guard 10. In the presentinstance, this guard is formed of fabric, as for instance a woven wire fabric, and in this form ofguard each end thereof is provided with a binding strip 11 and each end is secured by one or more, shown as three `in number, coil springs 12 with abracket 8 whereby the guard is maintained under tension so that it will normally retain its upright position and be returned to its normal position when flexed therefrom. In the present instance each guard is provided with'a large'or reinforced upper edge 13 which, in the formshown, consists of a series of spirally wound wires effective also to assist in maintaining the side-guard under tension. The lower edge of the guard is preferably provided with a longitudinally extending wire 14 thereby reinforcing it, and it is tied at intervals by Vmetal rings to the spiral spring connecting resist any compressive force applied thereto. It will be observed that in the present im proved structure the supporting brackets extend above the spiral springs so that the y' guard of whatever form maybe usedY is located above the tops of whatever forms of so ,tending wire tied to said springs and a spiral springs that may be used, so that when the stuffed mattressis in position the Y guard willralways be in proper position to prevent' any shifting and flattening and spreadingof the stulfed mattress, and main- .tain it in its box-like form.

In practice theV height of the guard member may be varied somewhat, but it is usuallyabout three inches high, and therefore extends about this distancey above the spiral springs. In other words, by reason of the presentV construction any compression of the side row ofy spiral supportingfsprings carries with them the side-guards which, however, by reason of the fact that'these Aside-guards are supported under tension, is

maintained Vin proper position to insure the advantages referred'to.

It will be understood that the various details may bemore or less modilied without departing from the spirit or scope ofthe present improvement, which broadly con-` sists in the provision of-means located-aboveV the spiral supporting springs for main-Y tainingthe shape of the stuffed mattress and preventing the spreading and flatteningV and shifting thereof. For instance, it .will bey understood that the supportingmeans as usedY herein and in the claims may consist of any means which supports or connects or ties the several springs into a structure 'whereby it maybe utilizedas a spring mattress. Y n Y The spiral .bed springs as frequently called, are not infrequently called box spr-ings'by .reasonfof the fact that the structure is usually covered with somesuitable form of ticking, that is toV say,cthe springs are usually entirely inclosed along the sides, ends and top with ticking, while the bottom is usually of some cheaper material and, of course, .when the spring is so covered the guards could likewise be covered-by the ticking also.- Of course, it .will be understood that thesprirng structure itself may be socovered without covering the side-guards if this is not desired.

A bed vspring comprising. supporting means, a series of spiral springs` carried thereby, brackets at each side extending nected to saidV brackets for preventing a Vstuffed mattress from flattening, spreading and sagging over the lengthwise edge of theV spring, andl means? connecting said vguard member lwith the outer row of springs, said means consisting Vof a longitudinally exlongitudinally extending wire yconnected means connecting said wires.

2. A bed spring comprising VsupportingY means, a series lof spiral springs carried thereby, said supporting means including a pair of Ycross members Y having upturned bracket portions extending above said spiral springs at the corners ,of the bed spring, a vside-guard stretched under Ytension between said brackets and extending above said spiral springs for preventing a stued inattres's from-flattening, spreading and Vsagging over the edge of the spring, and braces cony necting .said upstanding brackets with' the spiral spring supporting means.

Y 3. A bed sprin comprising rigid sup-V f porting means. inc uding crosswiseconnecting members at ythel endsA thereof, each of Vsaid connecting members having, at its.v ends upstanding brackets, a` guard member extending along each longitudinal edge of the I Vspring and stretched under tension between saidbrackets forpreventing a stuffed inattress from flattening, spreading Vand sagging. over-the edge of ythe spring, spiral springs carried bysaid rigid supporting means, each outer row thereof having their V.upper ends terminatingadjacent'tothe bottom 'of a guard member, and means connecting the bottom of the guard member with said spiral springs, said means comprising a longitudinally extending-wire tied to said Y springs and'to the ,bottom of said guard member.
