Be it known that l, JOHN A. STAPLES, a citizen of the United States, residing at State of New York, have invented certain newand useful Improvements in Springw'orlz, of whichlthe following is' a specification, reference being had therein to the ac My invention relates to spri11gwork for spring-beds, sofas, soiadaads, chairs aridall articles of furniture in which springs are era-- ployed, and the invention consists in the arraiigements and organizations of parts pointed out in. the appended claims.

' In the accompanying drawing, in which like-numerals refer to similar parts in the several figures, Figural is atop plan iew of a section of spring-Work made in accordance with my invention; Fig. 2 is a detail sectionalview'on the line 2- 2 of Fig. l Fig-3 is a top plan View of an embodiment of. ray

of Fig. .3.

' In the embodiment of my invention I may employany suitable form of springs 5 as the single cone springs supported on corrugated Wires 5" as in Fig. l or the double cone or the top and bottom coils of these hour glass springs are secured inidentically the same manger and in the manner in which the top coils of the sin le cone springs are connected,

it will be 0 y necessary to describe the method of fasteriiirg the top coils for a proper understandingol the erection of'the complete structure. lt is also to be understood that when the hour-glass springs are assem-= bled in a manner to be hereinafter made plain and the structure is in its complete cm, the top and bottom are identical, and

it is obvious that by reason of this fact, as in the case'of spring-work for beds, not only may the top and bottom be used intercharigeably but also the head and foot may be thus used, thereby adding to the life of' the structure and. providing a more com- 'fortable spring-Work.

In carrying out my invention the top coils of the springs are connected by clips 6, or in any other suitable manner, to a border-wire 7 or supportingwrires 8, which run: longitu irfally or transversely of the structure as preferredand are disposed in pairsslightly spaced apart betweenl the coils. These supporting-wires may or may not be secured to the border Wireand are carried in seats '9 formed in metallic supports orbrace strips 10 extending transversely or longitudinally of the structure and of predetermined length so that they will come out evenly With the border-Wire. The

' strips may be secured to the border wire by any suitable means though preferably by bending their ends to form loops or hooks 11 around the border-Wire as shown in Fig. 4 for example. The supporting Wires may be of any suitable form such as either plain in their intermediate portions as in Figs. 3 and l or provided with seats or ofisets at the points Where the coils are attached or Where the Wires fit into'the seats in the braces, as shown in Fig). 1'. The seats prevent the strips 10 from slipping on the wires, and also prevent the Wires from slipping on the" springs, as will be apparent from a consideration of Fig. 1. p

In order to prevent accidental dislodgm'ent of the supporting-Wires from the seats in. the braces, I provide means to'lock them in place, and While this may of course be accomplished in a variety of Ways I preferably em loy a length of Wire running substantia ly the length of the brace and forminga key 12, which is strung along the under face of the strips 10 andv throughslots or openings 13 in the down side Walls of the seats .9 and above the supporting Wires, as shown in Figs. 1, 2, 3 and 4.. Each end of the keys passes upwardly through the strips near their ends and then downwardly through suitable openings .14 ill the hooked ends of the strips and is formed into a hook 15 making a lock' for the hooks 11 to lock the strips to the bo-r der-Wire and prevent accidental displacement, as clearly shown in Fig. 4 for example.

While the ends of the supporting-wires 8 may or: may not be secured to. the border- Wire, in the forms shown they are not so socured and so do not 'make a knot or rough projection as they otherwise would, but are horizontally bent to form blunt ends to revent damage to whatever may be place on the structure, as, for instance, a mattress, and the borderrwire, strips 10, supporting- Wires 8, and the top coils lie in substantially the same horizontal plane. It is of course understood that the form of connecting-wire 8 illustrated'irrFi in connection witlisinr.-

gle cone springs may be employed, if desired, in connection with the other form of springs shown in Figs. 3 to 5, and that any form of spring may be used as desired.

The device may be furnished in knockdown form and may be readily assembled by unskilled workmen. The strips with the seats at predetermined intervals and vary ing in number according to the number of springs intended to be employed in the structure may be shipped in bundles, as may also the keys which are out to suitable lengths. In assembling the structure the springs are placed in position and their top coils secured to the border-wire and the strips 10 positioned transversely or longitudinally thereof as preferred and midway between the springs and secured. to the border-wire by bending their ends down to place, then they supporting-wires are placed in the seats provided for them in the strips and locked therein by the keys, which are readily strung through the slots 13 and 14 in the strips and also serve to lock the latter to the border-wire. The top coil of each spring is then secured to its adjacent supporting-wire and to the edge-wire when appropriate, and the structure is then complete when single cone springs areused;

when double cone springs are used the structure is next turned over and the then top coils of the springs, the original bottom coils,-

and associated parts are assembled as just described. This construction enables the parts to be. assembled in a mechanical and rapid manner and insures the proper location of the parts to hold the springs in position and provides a spring-structure having sufficient rigidity to maintain its form while allowing the desired spring e'ifeet, when any form of spring is used, and reducing the number of springs required for any given job as it distributes the load over the entire top, thereby equalizing the strain without in any manner impairing the flexibility of the structure. The braces and oonnecting-wires have a carrying-power whereby weight on one ls lpring is distributed to the others, and their exibility allows the springs to yield freely.

.While I have shown my invention applied to a small number of springs it isof course obvious that it may be employed. in structures having difierent numbers and arrangements of springs.

What I claim is:---.

1. In spring-work, a seriesqof springs, a border-wire and sup orting-wires intermediate the springs an secured to the larger coils of adjacent springs, brace strips interthe springs and having seat mediate the springs and having seats for the supporting-wires and secured to the border-- wires, and a key co-acting with each strip to retain the supporting wires in the seats.

2. In spring-work, a plurality of springs arranged in longitudinal and transverse rows, a border-wire secured to the larger coils of adjacent springs, supporting-wires intermediate the longitudinal rows of springs and fastened to the larger coils otadjacent springs, transverse brace st" 'ps intermediate 3 or tluYsupportingwir s and looped around the border wire, and a key cooperating with each strip to lock the supporting wires in their seats and the loops of the strips about the border wire.

In spring-work, a plurality of springs arranged in longitudinal and transverse rows, 'aborderuvire secured to the larger coils of adjacent springs, supporting-wires arranged in pairs intermediate the longitudinal rows of springs and fastened to the larger coils of. adjacent springs, brace strips intermediate the transverse rows of springs and having seats for the supporting-wires, and a key passing through. each strip above the supporting-wires to retain them in their seats.

4. in spring-work, a plurality of springs arranged in longitudinal and transverse ows, an upper and lower border-wire fastened respectively to the upper and lower coils of adjacent springs, supporting-wires intermediate the longitudinal rows of springs and. connected to the top and bottom coils of adjacent springs, transverse brace strips having end-hooks for the border-\vires and seats for the supporting-wires, and keys cooperating with the seats and having their ends passed through the endhooks of the strips.

In spring-work, a plurality of springs arranged in rows, a border-wire secured to the edge springs, .supportingavires intermediate the rows of springs in one direction, brace-strips intermediate the rows in the other direction and connected to the border wire, seats on ithe'supporting wires at their points of crossing the brace-wires and adjacent the springs, and means to secure the springs and brace-wires to the supporting wires at their seats.

In testimony whereof I affix my signaturein presence of two witnesses.
