To all whom 'it may concern:

Be it known that I, MORRIS SHALANSK1,

citizen of the United States,residing at] Indianapolis, in the county of Marion and} State of Indiana, have invented certain neu; and useful Improvements in Convertible} Chairs, of which the following is a specifi cation, referencebeing made therein to theaccompanying drawings.

My improvement relates ,to convertible chairs which may be converted into a number 'of-diiferent articles of furniture.

The object of this invention is to provide articles of furniture which may be used as a bed, sofa, settee, stools, chairs, and rocking chairs and which may be easily and i uickly converted from one form to another. I-at-' tain these objects by means of the device illustrated in the accompanying drawings, in which- I Figure 1 isa view, in perspective, of the chair member; Fig. 2 is a view of a removable tablearm used in connection with the chair member; Fig. 3 is a view of the corner. portion of the seat of the chair member; Fig. 4 is a view of the triangular seat portion used in conjunction with the chair members in forming the circular seat (Fig. 16;.) Fig. 5 is a view of a removable foot rest-used in connection with the chair member; Fig. 6 is. a view of a support used to support the triangular seat portion (Fig. 4) to form a stool; Fig. Tie a part sectional view showing in detail the method of supporting the chair back in its difierentpositions; Fig. 8 is a detail part sectional view showing the means for preventing the chair member from rocking; Fig. 9 is a view of the lever used .to set the winged portion of the seat of the chair member, looking in the direction of the arrow D in Fig.1; Fig. 10 is a view of the same looking in the direction of the arrow A in Fig. 9; Fig. 11 is a view of the pivoted "nut,looking in the direc-' tion of the arrow B in Fig. 7; Fig. 12 is a view of the member used to maintain thechair members in the circular'seat in Fig. 16; Fig. 13 is a detail view showingthe means for raising and lowering the w nged portion of the seat of the chair member; Fig. '14 is a view of the back of the chair member, looking in the direction of the ar row C in Fig. 1, showing the hingedly connected legs which support the back portion y-whenused to form a bed; Fig. 15 is a view of afull sized bed composed of four chair members; Fig. 16 is a view of a circular chair composed of four chair members; and Fig. 17 is a view of a settee or sofa composed of four chairmembers.

Like numerals of reference indicate like parts throughout the several views.

' The base 1 of the chair member is pro- .vided with the casters The rockers 3 are of the usual design and secured to the base 1 in the usual'way. The threaded portion at is mortised into and secured to the base portion land the threaded portion 5 is mortised into andsecured to the rocker 3 (Fig. 8). The rod 6 is provided with the handle or knob 6* at its topend and the threads 6* at its bottom end'to engage the portions at and 5 to prevent the-rocking of the chair member. A suitable recess 7 is formed in the seat portion 7 to accommodate the knob 6*.

'12 of the removable portion 10 to secure the portion 10 to the portion 10. Said back portion 10 is provided with the hingedly connected foot members 13 which fit in grooves in said back portion (Fig. 14). Said back portion is maintained in its different positions by means of the screw 14 and the pivoted nut 15. Said screw is provided with the swivel 16 to permit of the screws turning. 1 Said swivel is enlarged to form a handle or knob by which said screw is turned. The pivoted nut 15 (Figs. 7 and 10) is secured in suitable bearings in the rocker of the chair member.

' The supportin eyes 17 are secured to the sides of the roc ers and are provided for the purpose of supporting the arm portion 9 ,.the triangular seat portion 8 or the table vjections 17 to engage the eyes 17 Said triangular seat portion is provided w th the projections 17 to engage theeyes 17.

The winged portion 18" is'sec'ured to the seat 7 bymeans of the hinge'19 (Fig. 13).

-The rack 20 is hingedly' secured to .said winged portion by the hinge-21. The teeth .of said rack engage the teeth of the sector gear 22., Said sector gear ,is rigidly securedb to theshaft j23,'.,whichlis supported in suit} -able bearings at-its ends in the" rockers 3.

' 10 and fit the grooves 11 of The retainer 22 is journaled at its top'end on theshaft 23 and provided at its bottom fend with the rollers 22 to maintain said rack in engagement with said sector gear. The lever 24 is rigidly connected to the shaft 23 to, turn therewith. Sai d lever is; locked in its difi'er'entpositions by means of the p'oint25 engaging the teeth 26 of the sector 26. The point 25 is disenga ed from the teeth 26*! by pressing the flexi le steel lever 24 as indicated by the dotted lines in Fig.9, and reengaged by releasing the pressure on said lever.

' The corner portion 27 (Fig. 3) is secured to the winged portion 18, when the latter is in its lowest position,-by means of the de-. pending projections 28 which slip down behind the rearside of said winged portion.

The removable foot rest 29 '(Fig. 5) is connected by placing the grooves 30 under: the pins 31 and allowin the grooves 32 to rest on the pins .33. of said pins are located in suitable positionsportion 18. I y The stand 34:,(Fig. 6) is provided with the holes 314 the triangular seat ortion -8 to form a stool;

The center mem or 35 is provided with the tongues 35 which are similar'to the tongues 12 of the removable back portion the back portion 10 to maintain the four chair members in the circular seat shown in Fig. 16. Four of the chair members may be arranged to form a full sized bed Fig. 15). The arm portions 9 may be ad ed, one at each end to form a head piece and a foot piece to such a bed. The circular seat (Fig. 16) may be formed by using four-chair members, four. triangular seat portions and a center member 35 as indicated. e

A settee or sofa may be formed by aron the winged --ranging the chair members as shown in Fig. 17. The number of-chair members may be varied withouthdepartingfrom my inventlon. I

The operation of this invention is very simple. The chair member may be used as an ordinary'base rocker byunscrewing the v screw-rod 6 from the threaded portion 4.

It" maybe-used as an ordinary easy-chair by 'screiwing the screw-rod 6 into the threadedportion 4 to --prevent' its rocking, or b .lowering .the back, by turning the ball:or

v handleof'the swivel 16, to the desired posi .--tion and 'raising the winged portion '18 by" to receive the projections 17 of means of the lever24 it may converted into a reclining chair. The foot rest 29 may or may not be used 'as desired. Either one or two arm portions 9" may be-used. The

form the circular seat. This combination will be very useful in halls, hotels pleasure boats, private parlors and the lilre. This circular seat is'ccmposed of four chair members, four triangular seat portions 8 and the shown in Fig. 16, in which they are used to central member 35, as shown. The central member 35' nay be made in two sections-to be easily adjusted around a post or pillar.

portion maybe used to sup ort an ornament, a light, or any kind of ecoration.

What I claim as new and desire to secure by Letters-Patentis as follows 1. In a convertible chair of the land described, an adjustable back portion com-I posed of two parts, one of said parts;

hingedly connected to the seat portion thereof and formed with its top side shorter than its bottom side sothat four or more of said convertible chairsmay be used together to form' a circular seat, and the other of said parts removably secured to the said first part substantially as set forth. v

2. In a convertible chair, the combination with a rocker body, a base portion, a fixed seat portion, a hingedly connected seat portion, and a means for raising and lowering said hingedly connected'seat portion, of a screw rod having a handle at its top end and operatively secured in said rocker body,

a threaded plate secured in said base portion to be -enga ed by said screw rod, and an adjustable ack portion composed of two parts, one of such parts h ingedly connected to said fixed seat' portion and formed with its top side shorter than its bottom side and the other of said parts removably secured to.

said first part. I In test mon whereof I hereunto set my hand this tenth dayof-December-. I MORRIS SHAEANSKY. Witnesses: p I HARRY SHALANSKY,
