fJ t aly 2, 1935. F. J. TRAINOR SPRING FRAME SEAT Filed March. 8, 1935 Inveno (E/Md WWI/70A- Patented July 2, 1935 a 2,006,421 v I srme ras m sun Felix rm'inei," l N' wcastle, assign er Trainer National springcompany Newoastle l andiparticularlyto. a novel type ofehairfior-the like wherein all of the supporting-members are formed of spring material toproduc'e a yielding. 5 flexible structure fitting itself to the occupant with a suitable degree off re'silieney and [provid ingthe utmost comfort'. Another; advantage of my invention is that it may be incorporated in a number -of designs gi'vinga very pleasingand 10 striking effect suitable to-be madeup'in -varying 7 colors *and patterns A further, advantage is found in the'fact that byreason ot the allmetal-f" is extremely durable and may even'be'subjected' 15 to out of-door use without-appreciabledamage.

These and other objectsand advantages of my invention wil l become apparent to those versed in theart in the following description whichis made 29 wherein embodyingmy invention:

Referring first to that 'formfshownin tFi'gsbl' may: employ a" pair of runners l 0 and l I,, each having a major' length thereof normally hori zontally disposed. Tothese runnerslt and Il as"; 35 foundation members, I secure members generally designated by the numerals l2 and l 3 symmetrical one with the other so that the description of one will be, ddescription of the other.- Taking. the

From this arm rear- 7 portion I 8, the steel is then carried around and upwardly to form the rear bend l9 from which bend the steel then is carried upwardly to the v in -refe'rence to the aecam any s dmwmg,

Alsd'the upper ends of the back supports. aretied togetherby a bar-.14; in, the form herein vShown o ne t flIKEensasedJnyes formed in the top ends of: thoselsupports 20.; A;

seat 25 isrockably secured over the bar-23 and extends 'rearwardlybetween the, i'r'i elrrbers.- l2 and I 1 l llito have its rearl'end:liingedlytconnected along 'Fig. 2, a similar view of ajslightly modified the lowerendj oi." a 'b'ackl a which is hungg by. its. top'endfrom the bar 24. The seatZS and backjt may beef usual rigidstructure with resilient upholstery mereem'so that the distance between. the bar 23 and the rear hingeline of the; seat 25 c with theback 'fl ismaintained under load.

Now when;the.; seat or thus described l c up ig flw l om l -pos t on: as

indicated by-the dash lines in Figg 4, depending,

of course; uponthe weight of the occupantand to. what degree/the. Occupant, desires to rock; It

is'to be considered that the dash line position is merely illustrative and is not to be considered as the absolute P ition variousmemberswill assume. 7 vlllfl'ien the occupant sits down andleems backagainst thel hackle, the side members l2 and Ilwill tend to roll back along their runners while at the same; time the portions l6 and 2| 1 will assume sharper curves therebypermitting a the'balck supports-20 will permit a-fslightfiexing rearwardly thereof so as to permit ther' back to assume a more inclinedposition-.-"The hinging of 4 the seat and back permits assumed new. positions as indicated soil-that the seatand back will readily accommodate themselves to theoccupants position. As-the members and Bare thusdeformedunder load, the forward ends of tend to lift. Thus every supporting member outside of the seat and back may be flexed and deformed somewhat to accommodate itself readily to the load and to permit an easy rocking of the chair. As a matter of finish and to prevent damage to the floor, the forward ends of the runners Ill and II are preferably turned upwardly somewhat onithecurvesii and there'ar ends 'are' provided withturned up or rolled 'over ends.

In the form of the invention shown in Fig. 2,

the supporting structure remains exactly the same as that described above with the exception that the s L5 25 and back 26 are replaced with a length of fabric 21 hung between the bar 23 and the bar 24. Also for the sake of changed appearance, additional blocks 28 are placed on top of the arm rest portions I8. I

In the form shown in Fig. 3, the same support combined canvas seat andback 29 isemployed, in this case havingthehdditloh theretol ofan upholstered head rIestjIl and a seat cushion 3|.

Another modification from thatshownirithi: two.

formspreviously described is that onthe runners l0 and II Iadd as iperimposedplate 32 ease to have the rear end'of' that plate}! upwardly near the lrear 'en'daway from the runner and thence sharply'idownwardly to join. with and be secured to'the runner at its end.

aws thus added to pro vide anincreasing resalience tot-he rocking back or the sidefmembfers. l2 and I3 as their portions 211011 into contact therewith. Of course, the runners i0 andfl ifmay be omitted entirely in this form if desired, so that the bearing plates 3; then ny the members no and Malone.

In any thejformsabovedescribedi I achieve an extremely "comfortable chairwhich will settle back to accommodate the occupantwithout. any

tendency to pitch himiorward." The curves of the various members 'are so positioned andplaced as indicated as to prevent such pitching and at,

the same time prevent too'niuch ofithe springmembers' I contact with the runner over-a forward portion only thereof; the upper' ends of said legs being curved aroundtoward'each other to 'form' a re-- silient tie therebetween; a resilient back support" member extending from said tie andturned upwardiy; a seat bar interconnecting said front} legs; a backbar interconnecting said back support members; and a seat carried by said two While I havehereinshown-and described my invention in the forms as now best known to me, it is obvious thatstructurallchanges may be made without departing from i the spirit of the invention, and I; therefore do not'desire to those precise forms beyond the as may be'imposediby the following I 1.
