An object of this invention is to provides simple and inexpensive construction which may be readily attached to standard chair :10 frames for Fth'e purpose 'of providing an eX- j tended surface onwhichthe legs of an individual may rest whilebeing-seated to give what is knoWn -asfthe-chaise longue construction Another iobj ect of the invention is 1115 to provide an article offurniture hayingtwo V movable bottom memherg one of which when men inner positionlies beneath the other an'd when 'in a'n enter pos'itien iie-s' "in ed vance erthe other to form a continuationthereof.

A-rranged "to move on 'the "mainframeot the Fig.2 isasimilar sectionshowilrgtlie mov V furniture is, a bottom member 9 which I member 10 -'superimposed thereon, *both bottom fimembers bein'gfin this f i'nsitanceflIp'liolstered-"sprmg cushions mounted o'n rectangularframes. Thebottom'memoerS) is moy'zibl'e to an "outer position, its shown in Fig. *1, Wherei'tsubstantielly elignswith the bottom member 10 and serves, inthis'instztnce; es mi extension or said bottom meiiriher "so that one sitting upon "the 5 bottom member 10' may rest his legs upon ith'e bottom member 9, s'o' th'a't the furniture will form i n thisinst'ance, What is known a-s achaise lo'ngu'e, V In order to guide th'e' bottom --member '9 from its'in'ner to "itsouter position antlyic'e versa, the-cross piece =2 hatsa metal eterehment strip 11 secured'thereto byscrews 12 or other means to project below-"the--"cross piece, such strip having slets 13fthrough lying beneath the cross piece 2 in abutment with the undersurface of the latter, as illustrated in Fig. 5, thereby permitting the adjustment of the strip on the tracks for frames of different sizes. The forward end of these guides 14 are secured at 16 to the underface of an angle iron or attaching piece 15 secured, to the rear face ofthe cross piece 5, the upper horizontal flange of the angle iron being in a plane of the upper surface of the cross piece. The guides 14 have-rear lower horizontal portions 145, inclined portions 14 and upper horizontal portions 14:. To the lower rectangular frame 9 ofthe bottom member 9 two angle bars or supporting pieces 17 are secured in parallel relation so as to project rearwardly from the rear of the bottom member 9 and provide rests 18 for a purpose hereinafter set forth,-and, at the same time, these supporting pieces extend downwardly at 19'from the rearward extension 18. One flangeof each angle iron support 17 has a slot 20through its depending portion 19 through which one of the guides 14 pass, while the other flange of the portion 19 carries a roller 21 for cooperating with the top surface of a guide or track 14. The angle irons or supporting pieces 17 have pivoted thereto at 22, links or swinging members 23 formed, in this instance, of angle iron and each being pivoted at its forward end at 24 to the horizontal flange of'the angle iron piece 15.

Secured, in this instance, to the outer faces of the angle irons 17 on the bottom member 9 are two rests or supports 25 which when the bottom member is in its innermost posi-' tion depend into the open bottom frame formed bythe cross pieces 2, 3 and and which, when the bottom member9 is inits outermostposition, rest upon the floor surface; upon which the furniture-legs 1 and 4 rest. 7 a

Helical springs 26 secured at 27 to the supports 19 andat-28 to the swinging members 23 serve as means for assisting the user ofthe chair in moving the bottom member 9 from its innerto its outer position, the springs being under tension when the bottom member is in its innermost position and beinguntensioned when the chair is in its outermost position due to thefact that the springs connect with the swing members. A on or depression 29 is provided in the front lower portion of the frame 9 of the bottommember 9 and thecross piece 5 is provided with a pocket or depression 30 in its front face;

This arrangement permits the hand of the user of the chair to be readily engaged with "the underside of the bottom member 9' to facilitate the movement of the latter toward and from its inner position.

The bottom member 10 rests, when the chair is inthe position shown in Fig. 2, on

1 the bottom member 9. 'However, whenthe bottom member 9 is moved to its outer posi tion, the bottom member 10 is caused to rest at its forward portion upon those portions of the angle irons or supports 17 which extend in rear of the bottom member 9. The

rearportion" of the bottom member 10 may f be supported by a supporting means comprisare secured to the inner faces of the frame pieces 3. Normally this supporting means tends to swing forwardly so that its arms 32 will cooperate with stops 36 formed on the plates 34. In its forward position the supporting bar 31 lies in advance of the front surface of the upholstered back 6 so that it .willserve as a support for the rear end of the bottom member 10. As the bottom member 9 moves inwardly, the rear surface thereof cooperates with the crossbar 31 and moves the latter automatically toward the rear, but

still inadvanceof the pivotal axis 27, so that r the weight ofthe cross bar is so positioned that as the bottom member 9 is'moved forwardly, the cross bar automatically moves forwardly to supporting position.

The operation of the invention will be understood from the foregoing, but it may be summarized as followsz-Assuming that the parts are in the positions shown in Fig. 2 and it is desired to shift the movable bottom member 9 to its outer position, as shown in Fig. 1, the hand is engaged with the bottom member, as shown in dotted lines in Fig. 2, and the bottom member is pulled upwardly and outwardlyor forwardly. As it moves outwardly, the rollers 27 move on the trackway 14 and the swinging arms 13 tend to move the forward portion of the bottom member upwardly, so that the legs 25 will clear the cross piece 5. Later the arins 23 swing downwardly and the legs 25 come to rest on the floor or surface on which the furniture rests. This movement of-=the bottom member 9 outwardly is assisted by energy stored in the spring 26, when the bottom member is moved to itsinner position. As

the rear wall of the bottom member, moves I out of engagement with-thecross piece31, the .-latter moves forward-1y. Thebottom p member 10 is now removed from the bottom member 9 and is placed on the cross piece 31 and also. on the rear extensions of the angle irons 17. Toadjust the furniture from the position, shown'in Fig. 1 to that shown in Fig. 2, the bottom member-10 is moved from its position, shown in Fig. 1, and placed on the bottom member 9. The latter-"again is elevated and pushed rearwardly andgin bein ushed rearwardlythe rollers 27 m,

on the guides 14 and the arms 23 swing upwardly and rearwardly so that the leg 25 again clears the cross piece 5. The rear sur-;

agae'ogesa the upholstered back 6. At the same time,

the extensions on the angle iron'pieces 17, as

, well as the supports 19, will lie beneath the v upholstered back'in the chamber or recess.

As the swinging arms 23 move downwardly and rearwardly, theyplacethe springs 26 under tension-so that they are in COHditiOn for assisting in the movement of the bottom member 9, to its outer position,

What I claim as my invention and desire to secure by Letters Patent is: I
