CUSHlON SPRING SUPPORT.

SPECIFICATION forming part of Letters Patent No. 777,208, dated December 13, 1904. Application filed April 3, 1903. Serial No. 150,869. (No model.)

- To all whom it may concern.-

cation.

This invention relates to improvements in cushion-spring supports, and refers more specifically to an improved skeleton support formed of underlying wires of peculiar configuration.

The salient objects of the invention are to provide a construction in which each row of cushion or mattress springs is supported entirely by a single supporting-wire, thereby reducing to a minimum the cost of the substructure; to provide in a construction of this character means for supporting the springs rigidly against tilting movement; to provide a construction in which each spring is united or fastened to the supporting wire or rod by means of loops formed in the supporting-wire, through which the lower coil of the spring is conveniently passed to be attached or de tached; to provide a construction which is suitable for use with an ordinary cone spring and without specially shaping the latter, and in general to provide a simple, eflicient, and economical construction of the character referred to.

To the above ends the invention consists in the matters hereinafter described, and. more particularly pointed out in the appended claims.

The invention will be readily understood from the following description, reference being had to the accompanying drawings, forming a part thereof, and in which- Figure 1 is a view in side elevation of the lower end portion of a spring engaged with and supported by a supporting-wire embodying the invention. Fig. 2 is a view similar to Fig. 1 looking in the direction of the sup porting-wire, the end of which is shown in cross-section. Fig. 3 is a bottom plan view of the supporting-wire with spring in position. Fig. 41 is a View of a modified form, showing the use of a cross supporting-wire.

Referring to send figures, 1 designates as a whole a vertical cone spring such as is commonly employed for cushion and mattress springs, and 2 a supporting-wire upon which the lower end of the spring is seated. The supportingwires are arranged to extend across the cushion or mattress frame in the usual manner and at distances apart at which it is desired to space the springs. Each wire is also provided at suitable intervals throughout its length with laterally-extending V- shaped loops or bends 3, located at points of engagement of the several springs therewith. The width of these V-shaped loops is less than the internal diameter of the lowermost coil 1 of the spring 1 and is of peculiar shape in side elevation, as shown clearly in Figs. 1 and 2- that is to say, the straight or main portions of the supportingwire 2, while extending in the same general direction, occupy planes one above the other, as shown by 2 and 2, Fig. 1. The loop or deflected portion is bent to extend laterally, as indicated at 3, Figs. 3 and 4;, the arm of the loop adjacent the portion 2' being bentdownwardly into the same plane with the opposite arm of said loop, as indicated at 1, Figs. 1 and 2. This V-shaped loop extends beyond the periphery of the lowermost coil of the spring 1 and is then bent upwardly and back upon its own plane, the end thereof extending downwardly between its arms 3 to form the smaller loops 5, which encircle the lowermost coil of the spring 1 when in use. The extreme end of the V-shaped loop, with the overlying coilof the spring, forms the eye 6, through which a cross supporting-wire 7 may be passed, if desired, as shown in the modified form by Fig. 1. Preferably at the points of contact between the supporting-wire and the lowermost coil of the spring recessesS and 8 are formed in the supporting-wire, which recesses are occupied or engaged by said coil and hold the spring against movement longitudinally of the wire.

The spring is mounted as follows: The end 1 of the coil 1' is passed over the recess 8 in the wire 2 and in a screw-like manner through the small loops 5, underneath the wire 2, and into engagement with the recess 8, then continuing its circuitous route until it comes around to the starting-point, where the tendency is to pass under the wire 2; but instead it is manually pressed upwardly so as to pass over the wire 2 in the recess 8 until it rests against the arm, as shown more clearly in Figs. 3 and 4. The spring is thus conveniently attached to and detached from the supporting-wire and firmly and immovably held in an upright position.

It is evident that variations may be made in the form herewith presented without departing from the spirit of my invention, and I do not, therefore, confine myself to the particular form shown.

1 claim 1. A coiled-spring support, comprising a wire provided at its spring-engaging portion with a lateral extension having formed at its outer end a transverse loop for receiving the lowermost coil of said spring, whereby the end of said coil is threaded over the main wire at one side of said extension, through the loop at the end of said extension, under the main wire at the opposite side of said extension and around to the starting-point, substantially as and for the purpose described.

2. A coiled-spring support comprising a wire provided at its spring-engaging portion with a laterally-extending loop the width of which is substantially the same as the inside diameter of the lowermost coil of said spring, said loop being provided at its outer end with a pair of transverse loops, whereby the end of the lowermost coil may be threaded over the main wire at one side of said laterally-extending loop, through said transverse loops, under the main wire at the opposite side of said laterally-extending loop and around over the main wire at the starting-point, substantially as and for the purpose described.

3. A coiled-spring support, comprising a wire provided with a laterally-extending loop and having therein adjacent the opposite sides of said loop indentations on the upper and lower sides of said wire, respectively, said laterally-extending loop provided at its outer end with transverse loops adapted to receive the lowermost coil of said spring when passed therethrough and through said indentations in the manner described.

4. In combination with a coiled upholsteryspring, a supporting-wire therefor underlying and overlying, respectively, the opposite sides of the lowermost coil of said spring, and provided at its spring-engaged portion with a laterally-extending loop having at its outer end atransversely-disposed loop adapted to receive the end of said coil as the same is threaded onto said supporting-wire in the manner described.

5. In combination with a coiled upholsteryspring, a supporting-wire therefor underlying and overlying, respectively, diametrically opposite points substantially in the middle of the lowermost coil of said spring, said supporting-wire being provided at its spring-engaging portion with a laterally-extending loop, the outer end of which forms a pair of transverse loops adapted to receive the end of said lowermost coil as it is threaded upon said supporting-wire, in the manner described, and a cross-wire-receiving loop in said wire underneath said coil, substantially as described.

6. An upholstery-spring support comprising a wire to underlie and support saidspring, said wire provided at its spring-engaging portion with a plurality of loops and recesses transversely disposed with relation to each other, whereby the lowermost coil of the spring may be readily screwed into engagement with said loops and recesses for the purposes shown and described.
