The main side frames of my combination chair and step-ladder consist of inclined Vvfront leg members 1 and upright back members 2,preferablysecured:relatively to each other by meansl of inclined brace members 3 and 4 attheirouter sides and by means of substantially horizontal brace members 5, the back members 2, being staggered, are positioned upwardly relatively to the leg niembers l. -These`si`de frames, there being two in number, aie spaced from and secured relatively tone'ach other by Vmeans Vofaback seat member 6 intermediate the upper andlower ends of the frameset the vupper ends of the leg members l, aback supporting *bracey member 'Tat the upperr ends of the upright vback members 2, and'astep meinber intermedi-` ate the ends ofthe leg members 1. At the back sides and near the'upper ends of eacli of the back members 2 are provided a plurali ty of spaced'a part, corresponding notches 22L whichy ai'e adapted' to receive a rod 9 secured at its ends tothe upper ends of the shiftable rear leg members 10. These rear leg members 10 vare vpreferably reinforced relativelyto each other by means' of hori- Zontal cross braces 7 near their upper ends and byA means of diagonal braces 12, as shown. best in Fig. 1. f

l Tlierod 9 at thenpper ends of the rear leg members 10 is preferably secured in position in the notches 2a at the back side of the members 2 by means of the rod positioning strips13, which are sliiftably secured to the back side of theunembers 2 by means of screws 14 and secured relatively to each other by means of a brace 15 'so that the strips 13 may be shifted simultan'eously,y The holes 13%l thronghwhieh the screws 14 extend are vertically elongatedv andproyided at their lower ends with enlarged holes 13" which extend partially therein from Ithe back side of the strip 'and are adapted` to receive the heads of the screws'14. Thus, it will be 'seen that in order to shiftthe strips 13 to permit the rod 9 to be positioned in the different notches 21, the strips 13 or the brace 15 connecting the same are shifted upwardly and outwardly, spacing the strips from the back side of the members 2,V permitting the rod 9 to be positioned :in the notches desired. The strips 13arethenshifted inwardly and permitted to drop, thus locking the rod 9 in the notches in which the same is positioned and providing a pivotal lconnection at the vpivotal connection with the main side frames relatively to said side frames, there is provided'a U-sl'iap'ed rearleg positioning inember 16,jwhich is pivotally connected at its 7 sides and near the rear cross portion thereof intermediate the ends of the members 10. The side portions 16a of the U-shaped meniber 16 extend forwardly through positioning members, preferably staples, 17, secured to the outersides and near the upper ends of the inclined braces 4. Theseside portions 16 of the member 16 are provided'at their lower edgesv witha plurality of notches 16h, which are adapted to receive the lower horizontalfportionfs of the staples 17. At the forward ends of the'side portions'16a'are provided grip portions 16c for raising the same at their forward ends and releasing the same from positive engagement vwith the .staples 17. lt`will be noted that by raising one of the side portions' lafof themember 16, both' guide portions Vare raised simultaneouslybyreason of the integral construction-of the member 16. To the middle portions of the cross or diagonal braces l2 of the rear leg members 10is secured the one end of Va tension spring 18 which is secured at its op,- posite end to the cross portion of the member 16, adapted to raise the same at its rear portion and retainf the side portions 16*1 thereof -in staples 17. Y Y,

Through the front edge of the back seat member Gis pivotally connected, by means of hinges 20, the front seat member 19, which is slightly narrower than theV member 6. Said'seat'member 19 is provided at its sides and rear portion with a pair of downwardly eXtend-ing inclined leg'menibers 21 and at the front portion of'its sides with substantially upright 'leg membersy 22. These leg members 21 aiid22` are secured together positive' engagement rwith the lll) and braced relatively to eachother at their' Y lower ends by means of a widecross member 23 which is adapted to rest on thefground or floor when the device is used asa straight?` back kitchen chair.` .The inclined 'leg mem-A bers 21 are further braced relatively to 'each' other by meansof a' step member 24 secured to the leg members 21 intermediate their The rear edges of the inclined leg ends. members 21 are positioned in engagement lil() with the front edges of thepinclined Vfront leg members 1 when .the device is .used as a Within the frame formed bythe front chair and are locked relatively to each other s' ier ber 19 and .the 'leg-'brace member 23zare 4foldably positioned the

foot restfmembers

27,and 28. The foot rest member-27 is U-shaped and is pivotally supported at the `upper ends' of its side members 27 to near the .upper ends of the `leg members 22 and is adapted `to* be shifted forwardly therefrom.- To the lower vends of the .inner sides and )near-.the

rear edges of the side members 27aof the foot rest member 27 kare pivotallyconnected the lower ends of the side members "25W-ofL the U-shaped foot -rest supporting member 29, as shown best in Figs. 3, 4 and 1.6 -of :the drawings. This U-shaped member 29 is adapted `to support the free end vof the foot rest lmember 271m various positions .relatively to the main portion of theclhair, -the foot rest member 27 as showin-by solid lines in lFig. 4, Abeing support-ed in an :outward position by the member 29-engagingithe cor-l ner or .step braces 30 secured-in th-ecorners between `the brace member Y23 Aand -the inclined leg members l2l.l ySuch brace inembers 30, as described abov'e,are secured lin all Athe lower corners between the inclined leg -members -l and '21 and .the-,several step niembersto reinforce the struct-ure when the same is used as afstep-ladd-er. i

At 4the upper side `and near the :rear portion of Ithe rear seatmember .-6 :is secureda back positioning member S32 which is ,provided with a longitud-inalslot 32a for receiving the lower end of the back rest member 31. This member 3l is positioned at its upper end in engagement with the back supporting brace member 7 and is held in engagement therewith and within the slot 321l of the member 32 by means of a tension spring 33 secured at its upper end to the back side of the member 31 and at its other end to the seat member 6. The back positioning member 32 is also provided at its frontportion with a cutaway portion 32b into which the lower end of the member 31 may be positioned and retained in said position by the spring 33.

On the outer sides of the inclined braces 3 of the main side frames are pivotally mounted intermediate their ends the chair arms 34, which are adapted, when in downwardly' shifted positions, to rest on the chair arm rests 35 secured to the front sides of and intermediate the ends of the braces 3, as shown in Figs. 2 and 4. The normally rear ends of the arms 34 are provided with bifurcated portions 34a, which are adapted tol straddle the chair arm brace members 36 secured near the front portions of the outer sides of the members 2 for stabilizing the chair arms when in a downward position. Gn the one chair arm 34 is adapted to be removably mounted a table member 37, which is provided at its under side with an angle member 37a adapted to 4engage the inner edge vand mottom'isidie lof the Chair ,arm ito tu-clinally.extendingsuip 37b which lis adaptyed to engage fthe 4outer edgeiof ,the .chair arm, thus positioningthe table member ilatf erally :.tihereon. ,Y Y Y At' `the. upper ends :of fthe upright rback members 2 is .-pivotallyimounted .a platform 38 ahyimeansoffhingesf39. When the .device isiused .a .step-Sladder, assho-wn in .Fig 6, tliezpflzatform `38 is shifted ,to a substantially horizontal frposition and rests :at theiforwazrd portionof its under side at .the .upperends ofthe/.members21and the upper .edge of the Y bracemem'ber fr'.
