Referring now in detail to the drawings, i0 designates a frame for an upholstered chair comprising a spring seat foundation II and a sprin back foundation l2. The spring foundation ll comprises a. seat frame 13 having side walls [4, a front wall l5 and a rear wall IS. The frame I3 is supported at the front on le s IT. The spring back foundation l2 comprises a brack frame l8 having a top member 20, a bottom member 2|, inner side members 22, and outer side members 23, which extend downwardly forming legs '24, to which the rear portion of a seat frame I3 is fixed.

Referring to the seat foundation II, the same comprises a transverse, zig-zag shaped or sinuous supporting spring 25, disposed substantially parallel to the front wall it of the seat frame 13. The end loops or turns 2'! of the spring 25 are bent back beneath the underside of the spring. Said spring may be slightly arched if desired. The ends of spring 25 are attached to the upper edges of the side walls it by means of brackets 25.

One of the brackets 26 is illustrated in Fig. 9 of the drawings. The same may be made of sheet metal and comprises a bottom wall 26a contacting the upper edge of wall I 4. Said bottom wall 26a is formed with a central opening 26?), and a pair of openings 26c on opposite sides of the central opening. Extending from one end of the bottom wall is an upwardly and inwardly turned lip 23d formed with an opening 26c, aligned with opening 26b. Extending from the opposite end of the bottom wall 26a, are a pair ment loop 21. The abutment loop cannot be ac cidentally moved sideways out ofthe bracket.

As shown in the drawings, for the purpose of illustration, spring. 25 is spacedfrom front wall. I5 about A of the distance between wall l5 and l6,.although the'position ofthe spring 25 may be varied ii. desired.

Spring 25 may be lashed by a flexible guy 31!; as shown in the drawings.

to the front wall I5,

The guy 32 may comprise a sheet of burlap or other flexible or textile material. The sheet 32 is folded longitudinally about the spring 25, and the registering edge portion 324: thereof, are fastened to the upper edge of wall l5 by nails 33. The spring 25 is thus located between the folds of the sheet 32, and adjacent the fold thereof. The guy 32 prevents the spring 25 from being pulled away from the front wall l5, as will appear hereinafter, while permitting said spring to flex.

. Supported on the rear wall l5 and the transverse spring 25, are a plurality of spaced springs 35, which may likewise be sinuous or zig-zag in shape. The rear ends of the springs 35 may be attached to the top edge of rear wall l6 by brackets 31, to be described in detail hereinafter.

At the rear end of each spring 35 is an inwardly bent abutment loop or turn 36 engaged within a bracket 31. Each spring 35 comprises a main arched portion 38 extending from the bracket 31 to the transverse spring 25. Thus, the forward end 39 of the arch portion 33 of each spring 35 is supported by the transverse spring 25. Extending upwardly and forwardly from the end 33 of each arched portion 33 is an inclined portion 43 having at its forward end, an end loop 4| bent beneath said portion 43.

The bracket 31 illustrated in Fig. 8 of the drawings may likewise be made of sheet metal, or the like material, and comprises a top wall 43 contacting the top edge of rear wall l6 and a wall 44 extending downwardly from wall 43 and contacting the outer surface of said rear wall l6 of the frame. Wall 44 is formed with a pair of openings, adjacent the lower end thereof, to receive nails 45 or other fastening means driven therethrough for attaching the bracket 31 to the frame. b

Cut from the top wall 43 is a tongue 46, inclined upwardl and rearwardly from said top wall. Cut from the rear wall 44, is another tongue 41, inclined rearwardiy. The arms of end loop 36 of spring are engaged with the two tongues 41. Said tongues are then bent over the arms of loop 36. Arm 41 has an opening 48 to receive a nail or other fastening means driven into the side of frame wall l6. The advantage of the bracket 31 is that no nails have to be driven into the top thereof, as such operation would be difficult because wall 2| of the back frame is closed above rear wall l6 of the seat frame. A hammer may be worked sideways however, sufflciently to depress the tongue 43.

It will be noted that a part of the guy 32 is interposed between spring 25 and portions 33 of springs 35, thus eliminating noise. The portions 39 of spring 35 may be fixed to spring 25 by any suitable clips or hogs rings 45, piercing the cloth 32. The clips or rings embrace crossing portions of the

springs

35 and 25. Any suitable number of clips may be used for attaching springs 35 to the transverse spring, three such clips being shown for the purpose of illustration, for each of the springs 35.

It will be noted that the portions 43 of springs 35 may be freely flexed downwardly. Said springs are preferably tempered after the portions 43 are bent upwardly to'the desired angle, so that said portions upon being flexed will return to normal angle when pressure is released.

The upper ends of spring portions 43 are disposed above the front wall l5. They may be interconnected by a cross wire 41 threaded through the loops 4|. The transverse interconnecting wire 41 may be attached to said loops by straps 43. or any other suitable fastenina'means. The strap 43 may be made of a strip of easily bendable metal having loops 43 at the ends thereof.

To attach each loop 4| to the transverse wire 41, one end loop 43 of strap 48 may be first engaged with or threaded onto the outer arm 4| of said loop 4| The strap may then be wound around the other arm of the loop and around the wire 41 and then, the other end loop 43 may be threaded onto the outer arm of the loop 4|, as illustrated in Figs. 6 and 7 of the drawings.

The seat may be upholstered in the usual manner, but preferably no padding is placed between the spring portion 43 and the guy 32, so as to permit free flexing of said spring portions. Spring portions 43 produce a soft and comfortable spring edge at the front of the seat.

The back foundation |2 comprises a pair of transverse sinuous or zig-zagshaped springs 53 and 5| supported on portions 22 of the back frame "3. Spring 53 is parallel to portion 2| of the back frame, and spaced therefrom about V of the distance between portion 2| and 23 of said back frame. The spring 53 is substantially similar to spring 25 and the ends thereof are fixed within brackets 26 attached to portions 22 of the back frame.

Spring 53 is connected to the bottom portion 2| of the back frame by a guy 53, similar to the guy 32. The transverse spring 5| has a main central portion 5|a from the ends of which there extends forwardly and outwardly, inclined free flexing portions 5"), similar to portions 43 of springs 35. The ends of portions 5|a of spring 5| are attached to portions 22 of back frame likewise by brackets 26. Portions MD of the spring 5| may be flexed rearwardly, and the ends thereof are substantially in alignment with portions 23 of the back frame. Portion 5|a of spring 5| is connected to the top portion 23 of the back frame by a guy 55, likewise similar to the guy 32.

Supported by portion 5|a of spring 5|, and by spring 53, are a plurality of zigzag springs 53 extending up and down. Each has a central portion 56a from the upper ends of which there extends forwardly and upwardly inclined portions 56b, and from the lower ends of which there extends forwardly and downwardly inclined portions 560. The ends 56d of portions 560 of springs 56 rest on the transverse springs 53 and 5|. portions of the

guys

53 and 55 being interposed either between springs 55 and springs 53 and 5| S rings 55 are attached to the springs 53, 5| by clips 63, such as hog rings or any other suitable fastening means.

As illustrated in the drawings, each of springs 53 and 5| are attached to the springs 56 by a plurality of said clips 33. Spring 53 and portlon 5|a of spring 5| may be slightly arched, if desired, or substantially straight. The outer turns of portions 5") of springs 5| may be bent backward, as at He. The outer turns of portions 53b may likewise be bent, as at 5611.

Attached to portions 22 of the back frame, somewhat below the brackets 26, which attach spring 5| to said portions of said back frame, are brackets 26 to which there are attached short zig-zag springs 65, likewise inclined upwardly and outwardly, similarly to portions 5| b of spring 5|. Each spring 65 may have a bent back abutment loop 66 at one end engaged within a bracket 26, and the outer end turn of said spring may assure likewise be looped back as at 01. The outer ends of spring 65, 5i and portions 50b of springs 53, are interconnected by a member 10. Member 10 may be made of wire and has a top straight portion II attached to the loops 50d by straps 48. or any other suitable attaching means. Extending from portion II of member I0, are parallel arm portions 12 connected to loops Ho and 67, likewise by straps 43, or any other suitable clips or connectors.

Arms 12 extend substantially down to the middle of the back frame l3, and extending inwardly therefrom, are aligned horizontal portions 13 connected to substantiallycentral portions of the end springs 56, by clips I5 or in any other suitable manner.

At the lower ends of spring portions 500 are bent back loop portions 58c interconnected by a connector member 80 made of wire, or in any other suitable material. Connector member 80 comprises a straight horizontal portion 8| connected to the loops 56c by straps 40 or any other suitable clips or abutment members. Extending from the outer ends of portion are parallel arms 32 terminating short of portions 13 of connectors I0. At the inner ends of arms 32 are inwardly extending aligned portions 33 attached to the end springs by clips or connectors 80.

It will now be understood that portions 56b, as well as portions 560 of springs 53, may be flexed rearwardly to produce a soft resilient back. Likewise, the end portions Bill of the springs as well as the springs 65, provide resiliency at the sides of the back. In upholstering the back, it is preferable not insert anypadding material beneath portions 56b and 56c of springs 58, or beneath portions 5Ib of spring 5|, or beneath spring 35. a

In Figs; 11 and 12 thereis shown a modified construction; In said figures, the seat frame is provided with a transverse supporting spring 25 and a guy member 32, similar to that illustrated in Figs. 1 to 6 of the drawings. In Figs. 11 and 12, however, there is substituted for springs 35, springs 90 having portions 9|, similar to portions 33 of, springs 35, and similarly attached at their rear ends to'the rear of the frame. Furthermore, the forward end of spring portion 3| rests on the transverse spring 25, likewise similar to spring 35. I

However, there extends from the forward end of spring portion iii, an upwardly inclined spring portion 92 terminating above the front wall I5 of the seat frame, and extending from the upper end of spring 92, is a rearwardly and downwardly inclined springportion 93 having a bent back loop 93 at its outer end contacting the spring portion 9| at a point spaced rearwardly from the forward end of said spring portion, and attached to said spring portion by clips 95, or in any other suitable manner. The apices of

spring portions

92 and 93 are interconnected to a transverse wire 61, connected by clips 95, or in any other suitable manner.

In the modification illustrated in Fig. 13, there is substituted for the springs 35, a spring I00 having a portion IIlI likewise similar to spring portion 39 of spring 35. The forward end of spring portion IOI rests on a transverse spring 25, similarly to springs 35, the guy 32, however being omitted.

Extending upwardly and forwardly from the front end of portion IN is a spring portion I02 terminating above the front wall I5 of the seat frame. Extending downwardly and rearwardly from the upper end of portion I02, is a spring portion I03, terminating at I04, substantially at the level of the upper edge of front wall I5. Fixed to the upper end of wall I5,'and extending rearwardly therefrom is a strip spring I05 having a loop or eye I06 at its rear end, receiving the lower end I04 of spring portion I03.

In Figs. 14, 15 and 16 there is shown a seat frame H0, provided with a spring foundation III similar in every respect to the spring foundation shown in Fig. 1, with the exception that the transverse spring 25 being quite long, is supported at int rmediate points by zigzag springs H2, disposed there beneath, and attached at their front and rear ends to the front and rear walls I5 and it of the frame. The spring foundation III has springs 35, the same as in Fig. 1, which are additionally supported by the intermediate springs II2 parallel thereto. The ends of springs 2 may be fixed to the frame by brackets 26.

If desired, the additional supporting springs I [2 may be employed in chair seat frames, as well as in sofa seat frames.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

- As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
