FOLDING OR COLLAPSIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 561,136, dated June 2, 1896. Application filed February 27, 1896- Serial No. 580,965. (No model.)

To aZZ whom it may concern.-

Be it known that we, CHARLES J. SCHULTE and CHARLES F. WEHMEYER, citizens of the UnitedStates,'residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Folding or 001- lapsible Chairs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention has relation to improvements in folding chairs; and it consists in the novel arrangement and combination of parts, more fully set forth in the specification, and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the chair folded. Fig. 2 is a side elevation of the chair unfolded into the form of a vehicle. Fig. 3 is a sectional detail on the line so a; of Fig. 2, and Fig. 4 is a section on line y y of Fig. 2.

The object of our invention is to construct a childs chair which under ordinary circum-.

stances will serve the purposes of a high chair, and which under other circumstances can be folded or converted into a wheeled chair or vehicle by the simple manipulation of certain parts, the details of which will be more fully hereinafter described.

A further object is to construct such a chair with a minimum number of parts and to simand the latter being mounted near the lower end of said leg. When the device is used as a high chair, the upper ends of the extensionlegs 5 abut against the front transverse strip 8, secured to the under surface of the seat adjacent to and parallel to the front edge thereof. The upper ends of the extension-legs are connected by the links 9, secured, respectively, along the outer and inner surfaces of the respective legs 4 and 5, and the lower ends of the said extension-legs are similarly connected by the links 10 at a point above the wheels 7, the object of connecting the links on opposite faces of the legs being to allow the latter to freely fold, about the links when the chair is unfolded, as best seen in Fig. 2. Pivotally connecting the side bars 11 of the back with the lower extremities of the extensions 4 are the brace-bars 12 and the curved handle-bars 13, the medial portions of the latter and the lower extremities of the legs 4 embracing the free ends of the reduced extensions 14 of the rounds 15, which respectively connect the handle-bar and leg on one side of the chair with its corresponding handle-bar and leg on the opposite side, the extensions 14 each passingthrough the braces 12 to effect such connection.

When the device is normally used as a high chair, the parts are folded as seen in Fig. 1, in which case the shoulders 16, formed in the handle-bars adjacent to the pivotal ends of the braces 12, are firmly looked under and against the lower surface of the seat 1, and the free ends of the handle-bars are additionally secured to one of the legs 4 by a swinging latch 17. When thus locked, the chair cannot be accidentally collapsed by the child using it. The free ends of the handle-bars are connected by a rod 18, whose end is shown by the dotted lines in Figs. 1 and 2. \Vhen the parts are unfolded, as in Fig. 2, the members 13 serve as the handle-bars for the carriage or vehicle thus resulting.

Having described our invention, what we claim is 1. In a folding chair, a suitable seat, rigid legs depending from the same, extensions pivoted to said legs, wheels carried by the front pair of said extensions, an abutting strip carried by the seat against which the extensions may rest when the chair is in its normallyraised position, suitable links connecting the front and rear extensions, the opposite ends of each link being pivotally secured along opposite sides or surfaces of the front and rear extensions respectively, a back for said chair, folding connections between said back and one pair of the extensions, and means forming part of said connections for locking the parts against the seat when the chair is in its normally-raised position, substantially as set forth.

2. I11 a folding chair, a suit-able seat, rigid legs depending from the same, extensions pivoted to said legs, wheels carried by the front pair of said extensions, an abutting strip carried by the seat parallel to the front edge thereof against which the free ends of the extensions may rest or be held when the chair is in its normally-raised position, suitable links connecting the front and rear extensionlegs, one end of each link being secured pivotally along the outer surface of the rear extensions and along the inner surface of the front pair of extensions, a suitable back for said chair, suitable handle-bars pivoted to the back, rounds having reduced extensions connecting the handle-barsv at approximately their medial portions, suitable braces pivotally connected to the reduced extensions of the rounds, suitable rounds connecting the bases of the rear pair of extension-legs, said latter rounds having reduced extensions conneeted pivotally to the opposite ends of the braces, shoulders formed with the handlebars in such position that when the device is folded to raise the chair the said shoulders will be in engagement with the under surface of the seat, and a suitable latch adapted to further secure the free ends of the handlebars to the rear extension-legs, the parts all operating as and for the purpose set forth.

3. In a folding chair, a suitable seat, a back for the same, suitable depending legs, extensions for said legs, suitable handle-bars pivoted to the back, suitable braces pivotally connecting the handle-bars and rear extensions, and shoulders formed with the handlebars in such position that when the device is folded to raise the chair, said shoulders will be in engagement with the under surface of the seat, substantially as set forth.

In testimony whereof We afiix our signatures in presence of two witnesses.
