BED-SPRING.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed October 31, 1914` lSerial No. 869,516.

To all 'whom t may concern:

Be it known that I, PAUL W. KREUZKAMP,

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-Sprmgs, of which the following is a specification.

This invention relates to bed springs, more particularly to that form known as spiral bed springs, kin whichthe spring consists of suitable supporting means and spiral springs carried thereby for supporting the ordinary stuffed mattress, the object ofl the invention being to provide an improved spring of this kind in which certain of the springs may be utilized to partly f orm a side-guard for preventing the slipping, spreading and attening of a stuifed mattress.

I-Ieretofore it has been found practicable to provide onlyY flat bed springs, that is springs in which the bottom is formed of a fabric of some kind, with side-guards, and although it khas beenV highly desirable to make spiral bed springs with side-guards this has not been found practicable for various reasons, among others the difliculty of attaching and the difficuhty of maintaining such side-guards in shape and position, and therefore I believe that I1 l tov provide a side guard spiralA bed spring in which some of the `springs are utilized to form or pantly form the side-guards, and by means of whichthe shifting, spreading and 4flattening of a stuffed mattress are prevented'and such mattress maintained in its box-like shape, and therefore the object of ythe present improvement is the provision of'a bed spring of the class described hav- 40 ing side-guards which are inexpensively, but practically, applied Yand formed in part Aof vthe spiral springs themselves, and which structure is durable and practicable, so that the. advantages of the ordinary side-guard spring are obtained in the spiral form of bed spring. l

In the drawings accomp-'anyingand formingpart of this specification, Figure is a perspective view of this improved spring; Fig. 2 is an enlarged detail view of a part thereof; and Fig. 3 is a side view of the spring shown in Fig.` 1.

Similar characters of reference indicate corresponding parts throughout the several l 5v5 figures of the drawings. c 's am the first v The spiral spring supporting means may consist of any suitable framework 2. In the form shown it consists of a pair of longitudinal extending bars 3 shown as of angle iron 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. rThe angle' iron 'bars 4 are bent upward at their ends as at 8 so as to extend above the spiral springs a predetermined distance, thus forming guard supporting means or brackets 8', and these brackets are connected by braces 9 with the spring supporting means, and thejupturned portions of such brackets may also be suitably braced. In the present instance the lower ends of the braces 9 at each side of the bed spring are co-nnected with the outer longitudinal extending bar. 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 7 and connected along the inner sides of certain of the springs. In the present form of side-guard each spiral spring has itsends so bent upon itself as to form an upright vmember or projection 10 and one or more loops or eyes 1l at each side thereof. The end of the spiral spring may be utilized to form various Stylesv of uprights or projections, but in the presentinstance the end of the spiral spring is bent upon itself to form a loop 12, and then again bent .upon itself above said loop. to form another loop 13, and then bent downward and upon itself to form another loop 14 at the side of the upper loop, and then again bentupon itself to form another loop 15 at the side of the first loop, and the wires` then extend downward and are bent around one of the coils of the spiral spring. as at 16.

As each of the spiral springs terminates in an upstanding member or projection, it follows that a series thereof are located along eachA outer edge of the bed spring. Connected with the loops of the upstanding members or projections is a series of wires 17 extending in parallelism with the connecting rod 6 hereinbefore referred to. The end proj eotions are in turn shown connected by spiral springs 18 with the guard supporting brackets hereinbefore referred to.

Of course, it will be understood that as many loops may be formed in each upstanding bracket as may be found desirable in practice, and according to the number o f connecting Wires Which it may be desired to locate in parallelism.

From the foregoing, it Will thus be seen that at each side of the bed spring there is provideda side-guard stretched between the supporting brackets therefor, the members of which side-guard are connected With or formed as a part of the spiral springs upon Which vthe stuffed mattress rests, so that each guardis` not vonly connected at its ends vvith 'the brackets preferably through the medium of coil springs thereby to impart a tension to the side-guard, but each guard is also connected, Vand this in the present instance integrally With the spiral springs themselves, so that the guard tends to resist Y any compressive force -applied -to 'the spiral springs While the compression of the spiral springs causes the guard to move With them so that such guard is always in position to maintain 'the stuffed mattress in its box-like form and prevent the flattening and spreading thereof, or any shifting that might be present.

By the present construction it Will also be observed that the guard projects above the spiral springs the required distance and While the height of the guard may be varied somewhat it is usually about three inches, and therefore extends about this distance above the spiral springs, and it Will also be vobservedthat, by reason of the tension imparted to the side-guards through the medium of the coil springs, the side-guard very materially assists in maintaining the outer rovv of springs in their normal position.

By foldino the upstanding members in the manner shown it will be seen that each thereof has a certain spring action under pull of the longitudinally extending Wires so as to assist in maintaining the guard stretched under tension.

The 'upstanding projections of the sideyguard are tied by suitable Wires 19 to the longitudinally extending rod or Wire 6.

It Will be understood that the various details may be more or less modified Without departing from theV spirit or scope of the present improvement, for instance, it Will be understood that the supporting means as used herein and in the claims may consist of any means Which support or con- Vnects or ties the several springs into `a structure whereby it may be utilized as a spring mattress.

The spiral bed springs as frequentlycalled are not infrequently called box springs by reason of the fact that vthe structure is usually covered With some suitable form of ticking, that is to say, the springs are usually -entirely inclosed alongthe sides, ends and 'top with ticking, While the bottom is usutvveen said loops, each of ally of some cheaper material and, of course, When the spring is so coveredthe guards could likewise be covered by the ticking also. Of course, it Will be understood that the springV structure itself may be so covered Without covering the sideguards if this is not desired.
