SPRING. j

Patented July 1, 1919.

Application filed March 17,1919. Serial No. 283,226.

To all whom it may concern:

Be it known that I, J osnrn zen of Austria, residing at Brooklyn, Kings county, State of New York,*'have invented certain new and useful Improvements in Springs, of which the following is a clear, and exact description.

This invention relates to improvements in springs, particularly for use in connection with beds to support the apron upon which a mattress is laid. In other Words, my improved spring is especially adapted for use in connection with beds that do not employ the so-called bed-springs or spring-mattresses, but rather an apron which in turn is held or connected to a bed frame by springs. One of the objects of my invention is to provide a spring for the purpose set forth that will not collect dirt or vermin. To accomplish the foregoing result, my improved spring is formedto obviate corners or surfaces that would collect dirt.

I I will now proceed to describe my invention in detail, the novel features of which will be pointed out in the appended claims, reference being had to the accompanying drawing, wherein Figure 1 is a diagrammatic plan view of a form of bed for which my improved spring is especially adapted;

Fig. 2 is an enlarged perspective view thereof;

Fig. 3 is an enlarged fragmentary perspective view of an alternate manner of forming one of the loops of the spring, and

Fig. 4: is a perspective view of a modified form of spring.

To accomplish the results set forth, I pre fer to form the spring out of suitable material, such as spring wire, wound to form a single coil, said wire being provided with intermeshing or interengaging looped portions to limit the extensibility of the spring.

Referring to Fig. 2, the spring is formed out of a single strand 5 of suitable wire formed into a single coil 6, said coil acting to produce resilient yieldability. To limit the extensibility or contractibility, or in other words, the opening or closing of the 5o coil, I form the wire into loops 7 and 8 which are interengaged or passed one i through the other, the loop 8 being a closed a loop produced by securing that Ortion of the wire which is used to form sai loop 8 to Mnorrz, a citifull, 'or stop, the stop at the opposite end of the the coiled portion 6 thereof, as at 9. The

securement at 9 may be accomplished by spot-welding, wiring or otherwise. To form a closed loop the portion 5 of the strand of wire will be bent inwardly, as at 10, toward the coiled portion (5 to produce an end wall loop being formed by the curved end 11 of loop 8. The inter-engaging loop 12 is formed by bending the portion 5 of the strand 5 to lie in parallelism with the end 5 of said strand, said end 5 being an extension of the portion 5. The loop 8 will be formed to lie in a horizontal plane, while loop 12 will be formed to lie in a vertical plane. The outer end of the portions 5 and 5 will be bent to form a hook 13. When used in connection with the form of bed hereinbefore mentioned one hook 13 will engage eyes 14 at the end of the apron 15 of the bed, and the other hook 13 will engage eyes 16 in the bedframe 17. It will be apparent that my improved spring will yieldably support the apron 15 and at the same time will be prevented from being broken by being extended too far or opened too much. Should the weight upon the apron be suflicient to open the coil 6 to its utmost extent, the end 11 of loop 8 and end 18 of loop 12 would contact one with the other, thereby limiting the movement of the spring in the direction of the arrows 19 and 20. Such a condition could exist should any considerable weight be dropped on. the mattress of the bed. In this event, the breaking of the springs would be prevented by the stops mentioned. The reaction of snapping back of the coil would be resisted or prevented by the contacting of the stops 10 and 18 of loops 8 and 12 respectively.

By forming a spring in the manner above described, all corners or surfaces that would collect dirt are obviated, as it will be quite apparent from an inspection, of Fig. 2, that there will not be any surface upon which dirt can collect.

Instead of wiring or spot-welding the member 5 to coil 6 as indicated in Fig. 2, I may pass said portion 5 through the coil, as indicated in Fig. 3, thereby forming the closed loop 8 having the end wall 10.

Fig. 4 illustrates a modified form of my improved spring, in which the strand of wire is looped as at 21 and 22, said loops being passed one through the other, the ends 23 and 24 of the loops 21 and 22, respectively, forming stops.

Having described my invention, What I claim is i 1. A spring consisting Wire formed into intermoshing loops, the loops being formed in that portion of the Wire not employed to form the coil.

2. A spring consisting of a single coil of Wire, that portion of the Wire not employed to form the coil being bent overto form interengaging loops, one of saidvloops being closed, the other loop being an open loop.

of a single coil of,

3. A spring consisting of a single coil of ire, said coil at one end terminating in an open loop, the other end of the coil also terminating in a loop Which engages the loop first named, the-second named loop being closed, and means to connect the coiled porday of March, 1919.
