ApplicationApril 110',v 1947,., SeriahNo., 740;5861" 1i My present. invention relates; to them general classx-ofifchairs -'and' seats, andfmoreV speciiically toranfimprovedeasy chair-ofthe-oscillatable type includi'ng'afspringvv frame with" an'- oscillatabl'e seat; amstationarybase frame; and'stravelingfsup.- portssomtheebaseframe-for the spring or resilient frame'.

While the chair offmy-inventionfis I well adapted for various: purposes,A it A isn especially `designed for-use'in automotive'vehicles-,= aircraft; and railroad-cars; 'and the` chair may be equipped "with various 'types of-Y trimmi-ngs and accessories adapting it to different-fstylesoilfurniture;

The inventionconsists'- essentially incertain novel-1featuresoffconstructionf andrcombinations and arrangementsA of-'1:iarts` embodying a base frame-having travelingsupports;` al` torsionR or resilient@ spring frame.; mountedfonthe supports, andk asuspended combinationvbaclr-andiseat; as willhereinafter'be'described and more specifically set forth in the appendedclaims.v4

In the accompanying drawings I have illustrated one-- complete examplefof a physical embodiment of my invention whereinfth'eeparts jare combined:and'arrangediin--accordiwvitlr one mode I havei devised for the practical applicationof the. principles of my invention. It willihoweveibe understood that changes and alterations are contemplatedfand may'fbeemade in these exemplifying drawings, within the scope-,ofmy

claims, without departing, front the principles ofifmyg invention.

Figure 1 is a view in front elevation of a chair in which my invention is embodied; and

Figure 2 is a side view in elevation of the chair.

Figure 3 is an enlarged detail sectional View at line 3-3 of Fig. 2, showing an arm rest or pad attached to one of the loops of the resilient frame; and

Figure 4 is a side view of the parts in Fig. 3.

Figure 5 is an enlarged vertical transverse sectional view at line 5-5 of Fig. 2 through one of the front roller carriers or traveling supports for the frame.

Figure 6 is a horizontal sectional detail view through one of the traveling supports; and

Figure '7 is a vertical sectional detail view at line 'I-1 of Fig. 2 showing one of the rear traveling supports or roller carriers mounted on a side bar of the base frame.

In carrying out my invention I employ a rectangular base frame that includes a pair of spaced, parallel side bars I, which are united at their front ends by a cross bar 3 and at their rear ends by a cross bar Il. The front ends of thesehorizontal' side-bars are# bent under to form -feet 5; and'l at the rear: ofcthe-'basen framea-pair'of-wheels 8l are j'oi-xrrl'aled'` atl 1,' inorder thatltheffeet and wheels may co-act=iti-providingl a levelbase forVv the chair, and whenthe-fy feet are lifted -free of fasupporting surface;- the chair may bei'trundled from-placeto place :on-the two supporting wheels.

'Iflreresilient chairv frame;l which` is mounted on' the base, includes a-pair or 'integral vsi'deb'au's each comprising'. an; annula-rforj-y circular@ loop 8L; anupwardly and'frearwardlyk extending arm 9 with a transverse bar I0 connecting thearms, and each side barof the.framevvalsofincludes a downwardly -f extending leg II. Asz-4 th-us Vcoristructed-ithetworesilient-side-y bars' oitthefspring frame'- are 'supported on th'eloops andtlfiel legs, and -underthe weight-cfa loadthe-incllnedfarms and!

Iny the:l depressing move@- ment, however-the uppe'rends-*of the arms spread rearwardly and thev lower ends-ofthe legs' spread rearwardly# with a cushioned effect; l and1 when the load is lifted the arms and legsare'auto'- -maticallvrestored/1 toV normal position.` r

The two sideframes/'with' their'A single coils o-rcloops'farelientI or Wrought-to desired" shape by the useA offasui'table machine toolffromf spring steelstoclr-v which' may bey ilatfstrips, or round bars; eithei-r` solid or tubular*` in cross; section.

here'LshownA the V-sidebarsj I of-'the hase frame andthe single-coilsgL 8 are circularorrounded in cross' section fory co -acti'onwith---the travelling carriages or carrier-supports of the resilient chair frame.

At the rear of the chair the ends of the legs II are rigidly mounted in housings I2, I2. These housings, which form the carriages, roller-supports, or carriers, for the chair frame preferably consist of split or sectional castings that are bolted together to enclose the side bars of the base frame, and in addition to the performance of their functions as traveling supports for the chair frame, they guide the movement of the frame and prevent lateral displacement of` parts.

Each of the rear traveling supports or housings encloses a journaled roller I4 that is provided with an annular exterior groove conforming to the rounded side bars of the base frame. and the side bars, near their rear ends may be provided with stops S, or .bolts which limit thereafterward movement of the traveling housings I2.

The lower portions of the two coils or loops 8, 8 merging with the lower ends of the arms of the resilient frame are mounted, or rest upon two pairs of traveling rollers each of which is designated by the number I5. The pairs are arranged in tandem relation to afford seats for the two loops or coils, and they are journaled in two spaced traveling supports or carriers I6 and I'I. These carriers, preferably, are made up of bolted sections that enclose the side bars of the base frame, and the upper portions of the housings accommodate the loops or coils.

The carriers I6 and I'I are rigidly braced by a cross bar I8 with its ends threaded into the carriers, to prevent wobbling movement of the the loops and mounted on the rear carriers the frame also comprising arms extending upwardly and rearwardly from the loops and connected at their upper ends by a cross bar, a seat pivoted at its front end to the loops, and means suspending the rear end of the seat from the cross bar.

2. The combination of a chair having a base frame including two spaced parallel connected side bars provided with curved xed `feet at their forward ends and wheels at their opposite ends,

a pair of front travelling carriers and a pair of chair frame, and the loops are free to roll or glide coils or loops 8, 8, and a flexible back 2| for the I chair, of canvas or other suitable material, is suspended at its upper end 22 on the head cross bar l of the resilient chair frame. At its lower end the flexible back 2I is pivotally suspended at 23 tothe rear edge of the seat I9, thereby providing a comfortable, combined seat and back for the chair that readily adjusts and adapts itself to the occupant of the seat.

At the top of the two loops or coilsare provided arm rests or pads 24, 24, secured by screws 25, and these padsv preferably conform to the shape of the chair frame to which they are attached.

From this description taken in connection with my drawings it will be evident that I have provided a comfortable easy chair composed of parts that may` be manufactured with facility at comparatively W cost of production, and assembled with convenience', to assure a mechanical structure that is durable, and effective in the performance of its required functions.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: Y

1. The combination of a chair having a vbase frame including spaced parallel connected side bars provided with curved xed feet at their forward ends and wheels at their opposite ends, a pair of front 'travelling carriers and a pair of rear travelling carriers mounted on said bars and a resilient frame includingv two laterally spaced loops supported on the front carriers, and two legs extending rearwardly and downwardly from rear travelling carriers mounted on the bars and a resilient frame including two loops supported on the front travelling carriers, two legs extending from the loops having their ends mounted on the rear carriers, two arms extending rearwardly and upwardly from the loops and united at the upper end by a cross bar and a pivotally jointed back and seat suspended from the loops and said cross bar. f t

3. The combination of a chair having a base frame including connected side bars provided with curved fixed feet at their forward ends and i Vwheels at their opposite ends, a pairof front travelling supports each having `tandem rollers mounted on the bars, and a pair of rear travelling supports, each having a roller mounted on a side bar, and a resilientframe consisting of two side bars, each side bar comprising a loop resting on a pair ofthe tandem rollers, a leg extending rearwardly and downwardly from vthe loop and having its rear end united with a rear travelling support, and an arm extending rearwardly and upwardly from the loop, a cross bar uniting the upper ends of the arms, a seat pivotally mounted at its front end on the loops, and a flexible back suspending the rear edgeof the seat from the cross bar. y JOHN D. JULIAN.
