This invention relatesto an improved chair or sofa construction and more especially to a coiled spring assembly for supporting the upholstery for the back portion,
It is an object of this invention to provide a coiled spring unit or assembly which is adapted to be secured, to the back framework of a chair, sofa, or the like for supporting the upholstered back of the chair, thecoiled spring unit being provided with a reinforcing rod disposed intermediate its ends and extending from the upper border wire of the coiled spring unit to the lower border wire of the same, and which is disposed adjacent a substantially vertical row of coiled springs in the coiled spring assembly and to which it isconnected by a coiled wire extending from the upper to the lower ends of the coiled spring unit, as a result of which the weight of a person or object pressing against the coiled spring unit will be more evenly distributed throughout the coiled spring unit and to substantially decrease the pressure of the individual coiled spring against the padding an'd1upholsteryto thus extend the life of the upholstery,
Heretofore coiled spring assemblies for the backs ofchairs, sofas and the like, have been made up ofa plurality'of spaced vertically disposed rows of coiledsprings of the double cone type, the foremost coils of which have been interconnected at their proximate edges by horizontally'disposed coiled wires which extend trans- 'vrs'ely of the vertical row of coiled springs,- surrounding the'proximate portions of adjacent rows arcane-e springs. The foremost coils of the coiled springs disposed around the peripheryof the coiled spring unit, which is generally rectangular shape; :are generally surrounded and interconnected by a border wire of substantially larger diameter in cross-section than the wire used in the'forming of the coiledsprings or :the coiled substantially wider thanthe other parts of'the framework at the back of the chair, sothat the border wire iatthe'lower side of thecoiled spring unitrnay be stapled'or secured, in any other'suitable mannento the-frontedge of theframework, and theifearmost coils at therear ends of the l the coiled spring unit. a

(Cl. -479) other suitable manner to the top surface of the frame member which supports the lower end of It is another object of this invention to provide wires of substantially larger diameter than the coiled Wires, or the wires from which the coiled springs are. made, and which are adapted to extend within and over the length of the horizontally disposed coiled wires which serve to interconnect the rear ends of the vertical rows of coiled springs. These wires, which extend longitudinally of and are surrounded by the coiled Wires which connect thevarious vertical rows of coiled springs, are looped at opposite ends thereof to receive nails, serews or the like for securing these horizontally disposed uwires against the front surface of the framework of the rear of the chair, thus serving as animproved means by which a coiled spring assembly may be secured to the framework of the back of the chair.
Some of the objects of the invention having been stated, other objects will appear as the description proceeds; when taken in connection with the'accompanying drawings, in which- Figure l isa front elevation of a chair framework showing the improved coiled spring assembly applied to the frontsurface of the-back of the framework of the chair; a

Referring more specifically to the drawing the numeral Ill broadly designates the skeleton framework of a chaircomprising front posts .I l, rear posts 12, connecting front and'rear bottom rails l 4 and I5, respectively, connecting bottom side rails l6 and arm rests ll. i
coildsprings-maybe stapled orsecur'ed in any} Connected to and spanning the distance be-,
tween the upper ends of the rear posts of the chair framework it) is an upper horizontally disposed frame member 29. A lower frame member 2|, of substantially greater width forwardly and rearwardly than the posts l2 and the frame member 28, is disposed immediately above the rear bottom rail |5 (Figures 1, 4 and 6) being connected at opposite ends thereof to the proximate sides of the rear post I 2. Substantially vertically disposed frame members 22 and 23 are spaced inwardly a short distance from the proximate sides of the posts l2 and are connected at their upper and lower ends to the upper frame mem-- ably secured, a by nails, screws or the like 32,
to the associated frame members as shown in Figure 4.
The shape of the coiled spring unit 30 as shown in Figure l is of a type used in forming a T- shaped rear cushion for a sofa, chair or the like. However, it is to be understood that the invention is not limited to any particular shape or size of coiled spring'unit, the coiled spring unit shown in Figure 1 being by way of illustration only. Obviously, the coiled spring unit may be off-set on one side, both sides, or may not be off-set on either side, or may be of any other desired shape. Also, the number of rows of coiled springs and the number of springs in each row will be changed as the size of the coiled spring unit 'is changed according to the size of the chair, sofa or the like.
Although the coiled spring unit 30, as shown in Figure 4, is disposed on a slight angle relative to the vertical, the coiled spring unit 30 shall be assumed to be disposed in a vertical plane for purposes of description.
The coiled spring unit 30 comprises a plurality of spaced vertical rows of coiled springs 35 which in this instance are shown to be doubled coiled springs, that is; the end-most coils of each of the coiled springs are of the same diameter, the di ameterof the coils of the coiled springs gradually decreasing as they extend towards the centermost coil of each spring.
Referring to Figures 1 and 6, it will be noted that the two uppermost coiled springs in the outside vertical'rows are off-set with relation to the 'restof the coiled springs in each of these rows and the proximate portions of the endmost coils in each of the coiled springs overlap or engage one another and a plurality of coiled'wires. 38 are wound about or surround the overlapping portions of the coiled springs 35 and extend from .35 at the periphery of the unit 30 are engaged coiled wires 42, which surround the border wire 43 and are also interlaced with the proximate portions of the front endmost coils of the coiled springs 35.
It is with the parts heretofore described that this invention is adapted to be associated. Heretofore, in order to prevent the centermost coiled springs 35 in the coiled spring unit from bulging forwardly in such a manner as to place an undue pressure against the upholstering material 3|, a heavy fabric strap of, say, the approximate width of the diameter of one of the endmost coils of the coiled springs 35, has been suitably secured to the rear surface of the uppermost frame member 2| and has then'been brought forwardly over the upper edge of the border wire and downwardly across the front of the coiled spring unit at a point intermediate its ends and has then been suitably secured to the lower frame member 2|. This has not been entirely satisfactory, and in order to eliminate the necessity of providing a band of material of thi type, and also to provide an improved manner in which the coiled spring unit 30 may be secured to the framework it of the chair, there is provided a plurality of rods of substantially larger diameter in cross seotion than the coiled wires 36, and one of these rods 44 is disposed within the coils of each of the coiled wires 36 at the rear ends of the coiled springs only, there being no rods in the coiled wires 36 at the front ends of the coiled springs 35.
It may be observed in Figure 6 that each of these rods 44 extends from one side of the coiled spring unit 30 to the other and is looped as at 45 for the reception of nails, screws, staples, or the like for securing opposite ends of each of the rods 44 to either the rear posts l2 of the chair framework ID or the vertically disposed members Hand 23. It is manifest, that the rods 44, which are connected to those coiled springs 35 which are in the same horizontal plane as the offset portion of the coiled spring unit 30, are connected at opposite ends thereof to the rear posts I2 of the chair framework l0, and the 0pposite ends of each of the rods 44 which are not adjacent the off-set portion of the coiled spring unit 30 are connected to the vertically disposed frame members 22 and 23.
at their outer edges bya border wire 40, the op- The lowermost edges of the rearmost coils of the coiled springs 35 at the bottom of the coiled spring unit 33 in Figures 1, 4 and 6, are connected, as by staples 41 to'theupper surface of the transverse frame member 2| in the usual manner and the uppermost coiled springs 35 are connected as by staples 5|] to the front surface of the upper horizontal frame member 20 (Figures 2 and 6).
The lower horizontal leg of the border wire 40 in Figures 1 and 4 may be connected, if desired, by any suitable means to the front edge of the lower frame member 2|. Extending from the lower horizontal leg to the upper horizontal leg of theborder wire 40, midway of their ends in Figure 1, is a reinforcing rod 52, the opposite ends of which are bent at right angles and are inserted between the coiled wires 42 and the border Wire 40 to thus secure the opposite ends of the reinforcing rod 52 to the border wire 40. It .willbe noted that this reinforcing rod 52 extends. adjacent one of the rows of coiled springs 35 and is surrounded by a coiled wire 53 which is also interlaced around the proximate portions of the front endmost coils of the coiled springs 35 to thus serve in restricting the tendency of thecentermost coiled springs to-bulge' exces- "sivel-y 'forwardly of theborder wires.
The rearmost coils of thecoiled springs-35, "to the foremost coils of i which the reinforcing ro'd 52 is connected, are connectedto a reinforcing rod-*by a coiled wire fili, therein'forcing rod 55 and the coiled WireWS-being"similar to the reinforcing rod 52 and-the, coiled wire 53 respectively. The lowermost end of'the reinforcing rodf55- in [Figure-dis bent at right angles and-is looped *for reception of a screw, nail, or-staple *fOi'flSeGuliIlg the lower endof -the reinforcing rod :55 tothe transverse "member 2!. lt-willbenoted that the upper -end of the reinforcing rod 55 is "looped as alt- "-for "reception of a suitable screw, nail, on-the like for securing-the 'rodor wire"55 to the front surface of the upperfr'ame member of the chair and'also having reinforcing means extending from the upper to the lower end of the coiled spring unit to thusuincrease the life of the coiled spring unit as wellas any upholstery that may be applied over the same.
