"{Be it known that. I, RUDOLPH Dmitri., a cltizen oi the United States of America, und a" resident of Chicago, Cook county, Steteof Illinois have invented certain new and use Vful Improvements 1n Sota-Beds, of which the, following is e specification.

*Themain objects of this invention are to provide an improved forni of sofa `ned, which is yof simple construction :ind which has butV few parts to its operating mechn I nisin;y to provide a soffu-bedwhich is adept ed to be quickly converted from e sofa, to a bed or vice verse with but u slight expenditure oflabor; and to provide :i` sofa-hed in whichy the bed springs and the supporting mechanism therefor are adapted to be automatically folded into smell compass within the sofa or supporting Iframe, through the simple ect of lifting the sent traine.

y` A specific construction embodying this invention is illustrated in the accompanying drawings, in which: Figure 1 is a perspective view of the sote- Ibed in its closed or folded position. Fig. 2 is .a perspective View ot the sofa-bed in its open position. Fig. 3 is e transverse section taken on line A-A of Fig. 2. Fig. t is central, transverse section of the sofa -bed in its closed position. Fig. 5 is a fragmentary, end elevation of the sofa-bed with one end boord or member' removed. Fig. 6 is e plan View of the front rail and of the seatfreme in open position, with the bed-spring freine removed. Fig. 7 is e perspective view showing the front and inner sides of one oi the end members. Fig. 8 is al fragmentary, perspec- Fig. 9 is :L similr view of the rear rail. Fig. 10 is an enlarged, fragmentary detail showing the connection between rails and the end ineinbers.

In the construction shown, the soin` or supporting frame comprises end boards or menibers 1, 'which nre rigidly but detnehnbly con-- nected together by means of the front and

beck rails

2 and 3. Suid rails are provided' et their ends with longitudinally" directed hooks 4 which are adapted to enter sockets 5 in said endmeinbers and engage over pins or bolts 6 in said rsockets and thereby rigidly se cure seid end boards and rails together.

section 8 may/'therefore be quickly attached or. detached when desired.

The sofa sent 10 comprises a trame or lboxing' 11, in whichthe upholstering is secured. The frame is provided on the side which is down when the seat is closed and np when the sent isopen, with longitudinelly directed. supporting strips or

bars

12, 13 and 14, the two 'former of which :trendincent to the front edge of the closed sect, and the lutter adjacent to the rear edge of the closed sent, es shown more clearly in Fig. 4t.

The seat lrnrne 11 is hinged to the top of 'the front ruil 2 by means of hinges 15 which are secured to the bei' l2 :ind to the top of seid rnil. When in closed position, es shown in Fig. 4, the front edge ot the seat rests on the top oit' seid ruil 2, und when in open position the frame is inverted :1nd extends forwnrdly trom the ruil with the upper surfaces of seid strips on n level with the top of the rail, :is shown in Figs. 3 and 5. .A helical spring 1G is secured :it its ends to the strip 12 and the top of the ruil 2 in such manner that when the sont is closed the spring is under tension, rind nets to help reise the sent.

The bed-spring trame 1,7 is constructed in sections which hre pivotnlly connected together und, when the sofa-hed in closed position, the 4traine 17 is `folded end concealed beneath the sent freine. Seid Spring frameicomprises un outer, un inner or rear, und :in intermediate section. The outer section comprises end pieces 18 which are constructed of :ingle bars and nre rigidly secured to supporting bers 19, which extend along the'sent tranne nud are rigidly secured to the

strips

13 and 14. Suid bars 19 nre curved et their ends away from the strips so :is to support the end pieces 18 above the sent frame when the bed is open. The inner or rear section of the spring frume is like-l inner section. The outer and inner sections nre connected hy the interinedinte section,

wardly directed foot or or-nce 2G, adapted,v

when the bed is open, to rest on the strip 12 and support the intermediate section.

The inner edge of the inner` spring` freine. section is supported upon selil adjusting legs 27 which :ire ndopted to he automatically raised or lowered with the section und to support the section in either its lowered or elevated positions. The legs 2T eneh cour prise :i har piroted :it one end to n lin-ticket 28 which is `secured to the inner side oi the end hoard 11, adjacentI to the lower front corner otL the hozird. The other end of said bur is curved upwardly into position *for the inner end o't the ruil 2O to rest thereon. A connecting); har Qi) is piroted :it one end to the pivot pin 25, :ind :it the other end is pivoted to the leo' QT ncnr the curved end. llt'hen the hed is being' opened the connecting hzirs rnise the curved ends of the legs so esito support the inner spring tranne seci tion :it the desired height, sind when the hed is closed .said connecting hnrs lower the legs 27 to :in npproxiunitely horizontal position where their curved ends rest upon brncltets 30 carried on the end boards 1.

The cdgeot the sent iii-:une 1l which is at the trent when the hed is openiis supported on legs 31 which :ire pivoted to plates 3Q on the ends ot the sent tronic. 'llnch leg 3l is Vprovided with nn operating' link which vpivoted ut one end to the upper end ot the lee', nud nt` its other end is piioted to the end piece f )fl :it :i point about midway between the endsl oi seid end piece. When the sent irnnie is being closed, the houding ot thc jointl :it 2l reduces the distance between the pivotal point oi the leg` 31 und the pivotnl point ot the hnr il?, on the end piece 2?- und onus the operating' links 33 to turn the lees il to n. loi'zizontnl position nt the ends` ot' the sent freine, :is shown in Fig. 4.

For the purpose ot supportingthe tree or swinging cde'e of the sent 'traine and the outer spring` t'rzinie section `when the soinhcd is 'in closed position. nu arm 34 is pivotcd to the. outer side of euch leg 27 and extends upwardly und rearwardly, :ind is provided withnn inturned end 35 adapted to engage beneath the end piece 18. The upper or free end ot' seid :irin is supported nt jthe proper height., when the hed iselosed, hy ineens ot s hrncltet 3G carried on the end hoord, und when the hed is opened the end 35 rests on lthe end piece :20.

The bed-springs 37 are secured directly to the

end pieces

18, 23 and 20 and are adapted to be folded with the spring trarne sections. 4

The operation o'f the device shown is as follows:`l"i7hen it is desired to open the device, or to convert itJ from a sofaD into :i bed, the rear edge of the seat is raised and the sent turned 'forwardly on the hinges 15 to rai horizontal inverted position in front of the front rail 2. As the sent frame is turned outwardly, it carries the front spring section, vwhich is rigidly secured thereto, up wardly end outwardly over the front'rail 2. The pivots E24 travel through arcs of circles whose centers nre in the hinges 15.

is the pivots 24 swing about the axis of the hinges 15, the intermediate section 23 of the spring f tune is'grndunlly swung out of :i vertical position, as in Fie'. 1.1-, Yto a horizontal position. :is in Fig'. The, Weight of the i11- ner section ot the spring' frame resting upon the legs QT cnuses the links '29 to .swing the feet 26 of the intermediate section rearwardly enough so thatv they clear the upper edge ot the front uil Q. The parts theretore pass freely 4from the folded to the extended positions without interference with euch other or with the traine. When the sent frame reaches its open position, the feet 2G come to rest upon the hars 12, While the hair :2l cornes to rest upon the upper edge of the front rnil Q, and the rear section of the hed-traine is supported by-the legs 27 in horixontnl nlineinent with the front and middle sections. While the sentfrarne is heine opened the operating links 33 are xnored longitudinally hy the straightening oi the spring tronic, und the legs 31 are thereby turned down to position for supportingl the sent ironie. Then closingthe hed, the sections 23 :ire raised with the sont irnnie so the-.t the feet QG nnd 'the har -l will pnss inwardly clear oit the rflil 2. The inner spring' section is moved inwnrdly and downvnrdly by the movement of the seotions Q3, und the connecting hairs 29 lower tho legs 27 until they rest onv the brackets 30. The arms 34k lower by gravity until they rest on tht` hrnckets 36 in position to support the sent in n horizontnl position.
