CONVERTBLE CHAIR.

Specification of Letters Patent.

:"ipplication tried January 6, 1908, erial No. 409,415.

and useful Improvements in Convertible Chairs, of which the followingis a specifieation.

My invention relates to convertible cha-irs, and more particularly to that class of the saine in which the frames are foldable. i

One of the objects of my invention is to provide a chair which may be converted into a' cot or bed.

Another object is to provide a chair which may be converted into a double chair.

' Anothcrobjeet is to combine a table and convertible chair so that thetable will act as a support when the device is converted into a dou ble c'liair or bed.

Another object is to provide a convertible chair having a scat section adapted to act as va support when the device is converted into a bed,and a further object is to construct a chair having vthe framev sections adapted to confine a mattress, bedding or other body material. v

With these and other objects in view my invention consists in the details of construction and manner of operation more fully described in the following description and accompanying drawings in which like referencev characters refer to corresponding parts.

-In the drawings: Figure 1 isa side elevation of my device showing one arm of the chair detached and the forward portion of the mattress broken away Fig. 2 a front i elevation thereof showing a portion of one arm brokenaway; Fig. 3 a side elevation showing the chair converted into a double chair, the portion in dotted lines showing a further conversion into a' bed; and Fig. 4, a, lan view of the device converted into a. bed,

theinattress and U shaped section being removed.

My device generally comprises a base A, .a foldable back B, springs C, table E and stool F. The base A is made up of a rectangular skeleton frame 1, 1 12 supported by suitablel legs 2, 2vand 2', 2 on each'side thereof respectively. vertically swinging members 3, 3 have their lower extremities pivoted at 4, 4 to the sides and at the rear of the base. The vertical members 3, 3 project slightly forwardly as they approachtheir upper extremities which latter are pivoted at 5, 5 to the rearwardly projecting upper extremities of the', vertically swinging members 6, 6. Projecting forwardly from the lower ex- ,tremities of the members 6, 6 at some distance above and parallel to the base are the members 7, 7 which hitter have their forward extremities pivoted to the corresponding extremities of the vertically swinging U shaped section having a middle portion 9 and side legs 9, 9', by means of the pins S and the corresponding Vbayonet slots 8.

All of the frame members above described may be made from t. shaped bars bent to the required configuration and vpresenting their transverse and longitudinal webs (1, (1 and t), t/ on the exposed sides of the chair. The'transverse webs a, c of the members 1,1/ of the seat frame and of the members I, 3 and 6, 6 of the back may ybe. perforated at intervals to enable springs (il to be strung from the wens c on the one side to corresponding webs (1. .on the other side of the frame, thus forming a lower seat section and forward and rear back sections, the springs be-` ing strung longitudinally between the forward. member 12 of the seat frame and the tie rod 10 which latter is drawn transversely through the oppositely disposed longitiulinal webs b, b at the lower ends of themembei' 6, 6. The transverse webs (1.,afk Yare. cut

ties of thc members 3,3 and 6, 6 in order not to interfere with the swinging movement of these members. ',lhe upper extremities of the members 3, 3 and 6, 6 project sulliciently foiwardlyand rearwardly to space theforward and rear back sections a predetermined distance apart to accommodate a suitably folded mattress, bedding or other body between them.

lf desired ornamental fabric or-otliei' material may be sewed or tl'irown loosely over the. exposed sides of the springs, blut this is not material since the folded mattress embraced bctween the tightly strung springs forni avery desirable cushionv or upholstering for the'back and seat. tress at thetop of the back tends to compress the same at this4 point and to lspread the "folded sections at the lower eXtreinity'ttiei-eof, thus thc mattress taken toggtp forward swinging section betwcen the bars G, 6 form a yielding back.` 'Vlie pivoted U shaped section formed by the members S), 9', 9, may also yield upwardly and downwardl with the mattress to accommodate the swing- 'er with tl By folding the i'natingmovement of'forwardly projecting menibers 7,7. Pivoted at thelr lower ends on the transverse webs of the seat frame 1, 1, 12 are the sidearms 11, 11 bent at an angle and .having theirl transverse webs cut away as they ap roach their respective .ends to' accomlnodfate the back, their longitudinal web 3 being notched at 13 near their rearward extremities to enable the same to be sprung over the pinsl/i, 14 mounted on ,the members 3i, 3 to support the latter in an upright position. A'table E having a drawer in each end thereof is bolted to the rear of the webs a, a

of-the vertical members 3, 3', and a stoolF v15 -is movably'4 secured to the chair frame by' a suitabliklink 15.'. When the stool is not in seit `may .be secured beneath t'he tableto thecross bar 16 by a hook 17. When it is desired to convert the chair into a double chair as shown in'Fig. 3 the side "arms 11,-11 are sprung upwardly to enableV the notches to clear the pins 14, 14. which1 causes the- back members 3, 3 to be released and swung downwardly and rearwardly on their pivots 4, 4 to a horizontal position in i whichv position thetable E acts asa support and the U shaped section is' detached from the members '7, 7 and 'is replaced so that its vvmiddle, bar 9 rests on the free extremities Aof the members 7, 7 being held in place by means of thepins 8, 8 resting in the bayonet slots 82 and 83 respectively thus -forming a cross arm vbetween the two seats.- The sidearms 11, 11 may then be turned on their pivots 12,112 towards each other and are suitably secured together by a pin 18 in one arm passing into an aperture notsh'own in the other arm, both arms thus secured acting as an end arm for the chair.

sired, however the arms 11, `11,may remain inthel position shown in Figs. 1 and 2 the notches 13 being sprung over .the pins 8.

jThe chair may be further converted into a bed -by unfolding the back members 6, 6 rearwardly, the members 7, 7 acting as legs or props as shown in dottedl lines in Fig. 4.'

Themattress Dmay be so folded within the cha-ir so asl to unfold with the frame members l when the device is converted into a bed, and

the stool .F hooked'to the cross bars 16 may be sus ended out of contact with the Hoor beneat the bed. The side arms 1-1, 11 ar-v ranged as in Figs. 3 and 4 act as ahead to the bed.` i

When the device is' not intended to be con.- verted into a double or two seated chair the U 'shaped section may bey dispensedwith, if-

desired, as shown lin Fig. 4.

' Having now described my invention what' 'I desire to claim and protect by Letters Pat'-1 ent'isz.

1. A convertible chair comprising a base and a back having its lower extremities pivoted to said base and arrangedlto swing rearwardly 'into a horizontal position to form an an additional seat and horizontally swinging side arms mounted on said base arranged to support said back in' an-upright position and ltoo swing inwardly to .form an arm for'said` ase.

3. A convertiblev chair comprising a base, a back having front vand rea-r sections pivotally connected at their upper extremities and spaced apart 'to confine bedding, the rear section having its lower extremity pivoted to said base and the. front section having a forwardly projecting support rigidlyconnected to its ower extremity and spaced above said base also to confine bedding, the? said .back bein arranged to swing 'rearwardly and to be unfo ded to form a bed. and the said su ort being arranged to act as a'prop for saidjh 4. In a convertible chair, a base, a rearwardly swinging backsection having its lower extremities pivoted tosaid base, `a forwardly swinging back section having its upper extremities pivoted tosaid. irst men# tioned section, the said sections being arranged to swing rearwardly to-form an additional seat and to be unfolded to form a bed,

and a forwardly projecting support rigidly connected with the lower extremity of said forwardly Aswingingbac'k section arranged to act as an arm section betwe'en'said back and additional seat and asi-a prop2 for said bed.

5. A convertible chaircomprising a base having a foldable back pivoted thereto ,and arranged to be swung rearwardly in to a horizonta position and unfolded to form a bed, and horizontally swinging. side arms mountedl on said base arranged to support said back in anupriglht position and to swing inwardly to form a ead for said bed.

In witness whereof I have hereunto set my handthis 4th day ofJ'anuary, A. D. 1908.
