z j Application fi1ed June 21, 1917. Serial No. 176,120.

I! '0 all whom it may concern:

Be it known that I, Lmvnuncn HAUssIN- can, a citizen of the United States, residing at Alhambra, in the count y of Los Angeles and State of California, have invented new and useful Improvements in Combined Baby-Chairs and Common Chairs, of which the following is a specification.

This invention relates to a chair and particularly pertains to a combined chair for adults and children.

It is the principal object of this invention to provide a chair of the straight back type which may be used by adults and may also be converted so that it will servethe purpose of a high chair and then used by infants. 1

Another object of this invention is to provide a chair of the above class, the convertible portions of which may be compactly folded so that when the chair is used by adults it will have a sightly appearance and will not disclose cumbersome and objectionable parts,

Anotherobject of this invention is to proride a chair having a seat which may be swung downwardly from the back of the chair and is supported by members which will catch in their lowermost position to hold the seat against. movement,

Another object of this invention is to pro vide a foldable tray support mounted upon the seat supporting members and adapted to provide a safety guard, as well as means upon which a tray may be detachably secured.

It is a further object of thisinvention to provide a chair adapted to beused for the double purpose here specified, simple in construction, formed of few parts, and not liable to become easily broken.

Other objects will appear hereinafter.

The invention is illustrated, by Way of example, in the accompanying drawings in which:

Figure 1 is a View in perspective illustrating the chair and particularly disclosing it as adjusted to accommodate an infant.

Fig. 2 is a fragmentary view in side elevation illustrating the auxiliary seat and the manner in which it is supported.

Fig. 3 is an enlarged view in section, as seen on the line 33 of Fig. 2, illustrating the detailed formation of the supporting arm catches.

Fig. 41 is a fragmentary view in perspective illustrating the back of the chair when the auxiliary seat is folded.

Referring more particularly to the drawings, 10 indicates a chair seat, here shown as being formed of a single piece of wood. Asis customary, this seat is supported by a pair of rigid front legs 11 and 12, and back legs 18 and 14. The rear legs are formed with continuations producing posts 15 and 16. These posts are connected by cross braces 17 and 18 to form the chair back. Mounted between the cross braces are back rounds l9 extending downwardly from the cross member 17 and terminating within an auxiliary cross brace 20. The chair thus constructed may be used by adults.

In order that the chair may be used by infants, an auxiliary seat member 21 is provided. This member is substantially the same in shape as the seat 10, although of smaller dimensions and is pivotally connected to the auxiliary brace 20 by means of hinges 22 and 23. As particularly shown in Fig. 2, the hinges are not secured exactly along the edge of the seat 21, but are spaced a distance therefrom so that when the seat is down, a portion will swing beneath the auxiliary strip 20 and catch as the main portion of the seat hangs overthe strip 18, thus providing a combined lock and support which will relieve supporting members 24 and 25 from excessive strains.

The supporting members 241 and 25 are each formed of two metal straps 26 and 27. The upper straps 26 are pivotally secured to the outer round of the chair back by screws 28, while the lower straps are secured by screws 29 to the sides of the auxil- .iary seat 21. The contiguous ends of the straps are bolted together by hinge bolts 30 which permit them to fold when the seat is in its uppermost position. Referring particularly to Fig. 3 it will be seen that the lower end of the strap 26 is formed with a lock recess 31 and that the adjacent end of the strap 27 is formed with a tongue 32 adapted to snap into the recess when the two straps are longitudinally alined. A spring 33 is interposed between the nut of the bolt 30 and the side of the strap 27 so that the end of the straps will be yieldably held in relation to each other and will permit the tongue to easily snap in and out of the opening 31.

Cil

Mounted upon the bolts are tray arms 34: and 85 which are thus pivoted in relation to the supporting members and are connectcd by a cross piece 36. The two arms and this piece form a U-shaped tray support, upon which trays may be rested and also which will act as a guard to prevent small children from falling. The arms 3-1 and are provided with outturned lugs 37 which engage the under side of thestraps 26 when swung down and hold the entire tray support in a horizontal position.

In operation, the auxiliary seat stands in the position illustrated in Fig. 4: of the drawings, and is held in position by a suitable snap fastener. In this position the chair will have a sightly appearance and will be provided with a comfortable back formed by the braces 17 and 18 and the auxiliary seat :21 which is swung up between the two braces, as shown.

IVhen the chair is to be converted for use as a high chair, the auxiliary seat 21 is swung dounwardl 1 from the back; As it swings down, the straps 2G and 27 forming the supporting members will swing out- *wardly from a folded position to one in which they are longitudinally alined. When the seat is in its lowermost position, the tongues of straps 27 will snap into the recess '31 and lock the straps against accidental movement. It will be noted that as the supporting members swing, the springs 83 will be held against rotation by the small iangs 38-which project into longitudinal 7 slots 30 formed upon the faceof the straps 527. hen the'chair has been swung down to its horizontal position, the lower edge of the seat will be disposed beneath the auxiliary support 20 and the main portion of the seat adapted to rest upon and overhang the cross brace 18. It will be noted that the cross member 18 is formed with a beveled portion 42 to accommodate the downwardly and rearwardly swinging edge of the auxiliary seat. If it is desired to use the tray support, it may be swung down to a horizontal position where its downward movement will be further limited by the lugs 37; The bar 36' may then be swung across on its pivot and will be caught at its free'end by a fastener 3%. When the seat is afterward folded, the straps will be partially concealed, due to the fact that recesses -10 and 41 be made by those skilled in the art without departing from the spirit of my invention.

I claim:

1. A chair having a set of supporting legs, a fixed seat secured to said legs, a back portion extending upwardly from the'seatg said back having transverse braces; an auxiliary seat adapted to be normally positioned be tween said braces for vertical swinging movement, an intermediate brace to which said auxiliary seat is hinged, means where- 'by the lower transverse brace and the intermediate brace will rigidly support theseat when in its horizontal position, and folding side braces pivotally secured to the chair back and to the forward end of the auxiliary seat. i

2. A chair havinga set of'supporting legs, a fixed seat secured to said legs, a back por- 7 tion extending upwardly from theseat and having side posts between which are disposed transverse braces, an auxiliary seat normally adapted to fill the space between said transverse braces, an intermediate transverse brace secured to said'posts and to which the seat is hinged for vertical swinging movement; said intermediate and lower transverse braces being so disposed that the rear edge of the seat will swing befneath the intermediate brace and be heldby it and the lower transverse brace; folding side braces pivotally secured to each other at their one ends and pivotally secured to the chair and the seat at their opposite ends so that they will be in longitudinal alinement when the auxiliary seat is horizontally disposed, and means for temporarily locking said braces when in their unfolded positions. y

In testimony whereof. I have'signed my name to this specification; I

LAIVRENCE HAUSSINGER. 7
