Application filed February 8, 1915. Serial No. 6,681.

To all whom it may concern:

Be it known that I, JACOB SGHUMAN, a

citizen of the United States, and a resident ported onvlegs that are arranged in swing-- ing relation intermediate of their ends, whereby the chair can be raised and lowered by moving the legs together or apart, respectively, the chair having a handle POI? tion attached at a suitable point on the legs and in rear of the seat portion.

The chair has, a front extension which is suspended vertically from the front edge of the seat when the seat is in its raised position, but which extension is swung out so as to extend horizontally fromthe front of the seat portion, the extension being swung to and held in its extended position by the top ends of the rear legs of thechair.

The chair is further provided with a back 7 hinged to the back end of the seatportion,

'bil

the chair having means forholding the back in its upright position, the back being supported by the handle when it is, in its lowered position. This type of chair permits the use of the chair as an ordinary high chair, and in case an infant falls asleep while in the chair, the chaircan be lowered, the lowering operation swinging the extension out on the front end ofthe seat portion and then the back can be lowered to be supported by the handle part so that the chair can be transposed into a bed or crib and there is no necessity of attempting to remove the,child from the chair if it falls asleep. Thehandle is so secured to the chair that/it is locked to the seat portion when the seat portion is at its-uppermost position, and is thereby held up close against the back of the chair. There is an intermediate holding portion to which theseat can-be lowered, which intermediate holding, means holds the handle upright inits relation to the chair to prevent the lowering of the/back of the chair, but this intermediate holding means i is so disposed that when it supports the chair at an intermediate position, the extension on the frontof the seat portion is raised so that the extension at the front of; thechair and the back at the rear of the seat portion can both be arranged to be in position to allow the infant to lie down. The chair can also be fixed so that the front extension is raised to extend from the front ofthe seat portion, but the back of the seat portion is heldalso in: is raised position.

The invention further consists in details of construction that will be hereinafter more fully set forth and embodied in the clauses of the claims.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a side v ew of my improvedchair. Fig. 2 is a back view of the chair illustrated in Fig. 1, the bottom portion being broken away, and Fig. 3 is a side view of the chair illustrated in Fig. 1, this view showing the chair lowered to position where the child occupying thechalr can recline, this view showmg the tray removed from the chair.

The chair is supported by two pairs of legs, the forward legs 10 and the rear legs 11 being pivoted at 12, a pair of legs being arranged on each side of the chair and having Wheels'13 at their bottom ends so that when the chair is lowered to the position shown in Fig. 3 it can be wheeled on the floor, as will be evident. The rear ends 14 of the front legs 10 are pivoted as at 15 to the seat portion 16, the seat portion having any desirable type of side rails 17 and the rear posts 18, oneon each side of the seat portion, the rear post 18, beside its other functions, .actingto support a suitable tray 19, the arms 20 of whichare pivoted as at 21 to the rear post 18, being held inplace by any suitable means, usually springs 22 which project so that they can be operated and which snap into the slots 23 in the side rails 17 as will be evident. The seat portlDIl has, near its front end, pivotal supports 24 for the links 25 which are pivoted at 26 to the front ends 27 of the rear legs 11, the front ends 27 having their upper ends 28 cut away as at 29, the purpose of which will be described hereinafter.

At the frontofthe seat portion 16 are the hinges 30, these hinges ,being arranged preferably on each side of the seat portion and to which are attached theextensionfil, this extension 31 to hang vertically when the .chair is raised as shown in Fig. 1 and permits the extension to hang freely from the hinges 30, but abuts on the rails 34 so as to hold the extension 31 in place against excessive swinging or rattling. Pivoted at 35 to. the. rear legs 11- are the arms 36, which arms, combined with the cross-bar 37, form a handle for the chair. The handle has upper clips 38 and intermediate clips 39 whic'liextend from the front of the handle and provide staple-shaped or similar receptacles 'for the reception of the h-ooks'40,

which hooks are fastened to the back edge of tlieseat portion 16, and when the hooks are caught in the upper clips 38 the handle is held close up toward the back 41 which is pivoted as at 42to the seat portion and when in place can be secured by the tabs 43 which have button-holes 44 to receive the studs or buttons 45 to hold the back in'it's upright position, hen the chair is lowered to the intermediate clips 39 the handle is held in the position in which it is shown in Fig. 1,

but the lowering of the seat causes a sw1ng-' ing of the legs to separate the ends 14 and 27, the ends27 moving forward, and their rounded ends. 28' engaging the bottoms of the'rails' 34 and swinging the extension 31 tothe position substantially in extension of the seat portion 1 8, that is, to an approximately horizontal position. If the chair is I raised to release the'hooks from the intermediate clips 39 and still further lowered, the. legs are spread to the position shown in Fig. 3 and the supporting rod 46, which is fastened at its

ends

47 and 48 to the crossbarsof the arms 36 of. the handle, engages the end of the yoke 49 which is fastened to the, end of the seat portion 16.- With the handle in this position the tabs 43 can be unbuttoned from the buttons and the back 41 permitted to drop back until it rests on the handle, preferably on the cross-bar 48.

On the back 41 can be arranged a suitable cushion5O secured by tabs 51 to the buttons 52 to hold'thecushion 50 in place. A double cushion with a seat portion 53 and an extension portion 54 has a narrowconnecting strip 55 between these portions, and suitable strings 56 on the rear corners of the seat portion 53 can be tied aroundthe rear post I 18 tohold this double cushion in place. The

is avoided by means of this construction of chair. Vhen the infant falls asleep the chair is slightly raised until the hooks 40 are released from the clips 38, and then the seat portion is lowered to the position shown inFig. 3 which automatically swings the extension 31 so that it horizontally extends from the seat portion 16, this also straightening out the double cushion. As soon as the chair is lowered the tabs 43 are unbuttoned from the buttons 45 and the back can be lowered as shown in Fig. 3, and the child is .as'comfortable as if it were in a crib or bed, and a great deal of work is saved and acomfortable chair is provided.

It will be evident that this chair, while preferably made of wood on account of its lightness, can be made of metal and other materials, the chair being simply operated, its simplicity making its operation assured.
