GEORGE W. BUNDLE, OF SPOKANE, WASHINGTON, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO BUNDLE NOVELTY COMPANY, A CORPORATION OF WASHINGTON.

CONVERTIBLE CHAIR.

Specification of Letters Patent. Patented July 20, 1915 Application filed February 16, 1914-. Serial No. 818,938.

To all whom it may concern:

Be it known that I, GEORGE W. BUNDL a citizen of the United States, residing at Spokane, in the county of Spokane and State of lVashington, have invented certain new and useful Improvements in Convertible Chairs, of which the following is a specification.

This invention relates to chairs which are convertible, and its object is to provide a novel and improved childs high chair with a saddle seat, reclining back, spring seat and removable tray, and, furthermore, to

provide in a chair of this kind a structure claimed, reference being had to the accom' panying drawings in which Figure 1 is a perspective view of the chair arranged as a high chair; Fig.2 is a-vertical section thereof; Fig. 3 is a perspective view showing the chair arranged as a nursery or low wheel-chair, and Fig. 4 shows the chair arranged as a couch or reclining chair.

In carrying out the present invention, there is provided a chair structure characterized by front and rear legs 10 and 11, respectively, a pair of each of said legs being provided. The front legs are connected in spaced relation by a rung 12, and rungs 13 connect the rear legs in spaced relation. The front and rear legs converge upwardly, and the rear legs are longer than the front legs, their upper ends terminating some distance above the corresponding ends of the front legs. The upper ends of the rear legs, at the outer sides thereof, carry wheels 14, and the lower ends of said legs carry wheels 15, which may be ordinary caster Wheels. The wheels 15 are carried by the rear edge of the legs 11, and the diameter of the wheels 14 is such that they. project from said edge. Thus, these wheels serve as a rolling-support for the chair when the legs 11 are placed in horizontal position next to the floor, as will be hereinafter described.

The front legs 10 are pivoted at their upper ends to seat-supporting members 16, as indicated at 17, said members being flat metal plates. To the rear legs 11 are rigidly secured, intermediate their ends, forwardly extending arms 18 which are pivoted at their outer ends to themembers 16, as indicated at 19. On-the bottom edges of the members 16 are abutments 20 whichare engaged by the inner edges of the legs 10 adj acent to the pivots 17, to prevent said legs from swinging out of supporting'position.

The members 16 and the rear legs 11 are connected by brace bars 21 pivotally connected to said parts, the pivotal connection with the members being indicated at 22 and the pivotal connection with the rear legs at 23, the latter connection being near the lower ends of the legs. The braces 21 are slotted to accommodate the pivots 23, in order that they may be folded. The braces extend diagonally between the members and the legs.

To look 'the legs 11 in adjusted position,

a yoke 24 is provided, the two arms or branches 25 of which are rigidly secured to the members 16 and project rearward therefrom to extend between the legs 11, the latter having a suitable catch 26 to engage the yoke and thus lock the said legs in upright position. When the legs 11 are placed in horizontal position, a second catch 27 engagesthe' yoke and locks the legs in this position.

The seat of seat 29 hinged to the rear portion of said seat 28 to fold down on top thereof. When the seat 28 is to be used, the seat 29 may be swung upward and back-as shown in Fig. 3.

,The seat 28 is rigidly secured between side 35 in the rear portions of bars 36, one edge of the slots having notches 37 corresponding the chair is double, the same comprislng a nursery seat 28 and a saddle to the several positions the back-rest may.

. be locked, said notches being engageable by the bail branches.

At the front ends of the bars 30 is remov-v ably mounted a tray 38. Slotted ears 39 are secured to the bottom of the tray adjacent to the opposite side edges thereof to extenddownward over the outer ends of the arm rests 32, through which latter pass screweyes 40 over which the ears are slipped and clamped by wing nuts 41. The eyes of the bolts are on the inner sides of the arm rests,

" pivoted the outer ends of links 42 which extend downward and are fulcrumed intermediate their ends, as indicated at 43, on the members 16, to swing in a vertical plane. The inner lower ends of the links cross and ar pivotally connected by a pin 44, one of the links having a slot 45 through which the pin passes. Below the links is located a lever for adjusting the hei ht of the seat, said lever being bail-shape and having its branches 48 connected by coiled springs 49 to one of the links of the respective pairs, and fulcrumed to the members 16, the latter having slots 51 in which the fulcrum pins 52 work in order that the lever may be moved in the direction of its length to seat and unseat locking pins 53, the latter being carried by the branches 48. The rear edges of the members 16 have keeper notches 54 in which the locking pins 53 are adapted to be seated to lock the lever, and upon taking the pins out of the notches, the lever is left free and may be swung to raise or lower the seat. A downward swing of the lever swings the links in a direction to elevate the seat. To lower the seat, the lever is swung upward. The springs 49 provide a resilient support for the seat and allow the same to yield freely to the weight of the child occupying the same. The chair is also provided with a foot rest 55 carried by and mounted between the outer ends of two side bars 56 which are "pivoted at their inner ends, as indicated at 57 to the brace bars 21. On the front legs 10 are swiveled guide eyes or loops 58 through which the bars 56 slidably pass. I

Fig. 1 shows the chair set up as a high chair. To convert the chair into a low wheel-chair, the catch 26 is-swung to release the yoke 24, and the rear legs 11 are swung about their pivots 19 to come to horizontal position beneath the member 16, next to the floor, with the wheels 14 and 15 engaging-the latter. The chair is now wheelsupported. The legs 11 are locked in the new position described by engaging the catch 27 with the yoke 24. The front legs 10 are supported at their outer ends on top of the corresponding ends of the rear legs. The chair may now be used as a walker and jumper, the seat being low enough to allow the childs feet to reach the floor. If a nursery chair is desired, the back-rest 33 may be inclined rearward, and the saddle seat 29 swung upward and back to allow the child to occupy the seat28, as shown in Fig. 3. The tray 38 is also removed.

To convert the chair into a couch or bed, the back-rest 33 is lowered to serve as a head-rest as shown in Fig. 4 and a pad, mattress or seat extension 59 is placed on the seat 29,- said pad extending from the rear end of the seat and projecting from the front of the seat to allow its outer end to be connected to the outer ends of the legs .10, the same being swung upward as shown.

For a reclining chair, the parts may remain in the last-described position, except that the back-rest 32 is placed in a more upright position and the tray 38 is replaced, as shown by dotted lines in Fig. 4.

I claim:
