CHILDS CHAIR.

SPECIFICATION forming part of Letters Patent No, 317,668, dated May 12, 1885.

Application filed September 15, 1884. (No model.)

To all whom it may concern:

Be it known that I, FRANK F. PARKER, of Gardner, county of XVorcester, and State of Massachusetts, have invented an Improvement in a Childs Chair, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the construction of a combined high chair and carriage for children, wherein the bottom frame, which serves as the legs or support for the chair and its frame when used as a high chair, has its forward or front pivotal connection with the chair-seat frame in the line of the axle of the frontwheels, while the rear of the bottom frame, corresponding to the back legs of a high chair, is connected with the back end of the seat frame by a toggle-jointed link, which I shall call a toggle, so that whether the device is used as a high chair or carriage the middle joint of the toggle or that joint intermediate of those connecting the toggle with the seatframe and bottom frame is out of a line intersecting the said two outside joints, whereby the several parts are automatically locked or supported in position, whether the device is used as a high chair or carriage.

In the present instance a cross-piece at the front part of the bottom frame serves as an extension of or addition to the foot-rest attached to the chair-seat frame when the apparatus is used as a carriage, while, when the apparatus is used as a high chair, the said cross-piece rests against the front of the chair-seat frame and serves as a stop to limit the backward pivotal movement of the toggle and the consequent movement of the seat-frame in the bottom frame.

Suitable catches or stops are provided on one part of the toggle to engage other parts thereof and limit the movement of the toggle in one direction when the apparatus is used as childs carriage.

A suitable handle to enable the carriage to be trundled is, in this instance, pivoted to the arm-supports of the seat, the said handle being arranged to be swung on its pivots and rest against the bottom frame behind the chair proper when a high chair is provided. Further, the chair-arms are provided with slots and suitable screw-eyes, the former receiving lugs projecting from the side of a table and the latter being engaged by pins attached to inward! y-p roj ectin g extensions of said table, the pins on the extensions being provided with coiled springs which serve to lock the lugs in the slots and prevent their easy removal therefrom.

The invention is fully set forth in the follow ing description, and is particularly pointed out in the claims.

Figure 1 shows in side elevation a combined high chair and carriage embodying iny'invention, the device being shown as a high chair. Fig. 2 shows in side elevation the apparatus arranged as a childs carriage. Fig. 3 is a plan of Fig. 2, an d'Fi g. 4 is a detail to be referred to.

The seat A, provided with suitable, arm-sup ports, a, arms B,and back O,is rigidly attached to and supported upon the seat-frame of any suitable construction, but which in the present instance consists of the top pieces, 2, secured to the under side of the seat A, the bottom pieces, 3, having the front extensions, 4, the foot-rest 7, and rear extensions, 5, and suitable intermediate columns or supports, 6, con necting the top and bottom pieces of said seatframe, alias clearly indicated in Fig. 1. The front and back wheels, V V, have bearings in the bottom of the seat-frame. as shown. The bottom frame consists, essentially, of the coir nected sides, each having two main pieces, the like ends beingin a given plane to provide four legs to support the parts when used in ahigh chair. In the presentinstance the main pieces D E are secured together at d, and are braced near their lower ends by rungs 6, there being two each of such main pieces D E to form the two sides, which being connected with rungs and the cross-piece f form the whole of the bottom frame. This bottom frame is pivotally connected with the seat-frame in the line of the axis of the front wheels, the said pivots entering the pieces D, (see Fig. 1,) while the back of the bottom frame is connected at g with the toggle H, the upper end of said toggle being pivoted to the rear of the seat-frame. The toggle consists of the pair of bars H and the links Ii, the bars being provided with the stops h (see Fig. 4) to engage the links and limittheir movement in one direction when the parts are adjusted to provide a childs carriage.

Referring to Fig. 1, which shows the parts arranged as a high chair, it wil1 be noticed that the intermediate joint, t, of the toggle is out of a line intersecting the remaining joints of said toggle, so that the greater the strain exerted upon the toggle the more firmly are the parts retained in position, the cross-piece f of the bottom frame bearing against the front of the seat-frame and thereby serving as a stop to limit the movement of the toggle.

To change the parts from the high chair shown in Fig. 1 to theearriage shown in Fig. 2, the toggle is pushed at t, Fig. 1, toward the front of the chair to allow the seat-frame to be lowered in .the bottom frame, and the latter is moved on its front pivot, '6 to allow the wheels to support the body when the parts may readily be adjusted to the position shown in Fig. 2.

Ahandle, J, is pivoted to the arm-supports at J so asto allow it to be moved into the position shown in Fig. 1, while, when in the position shown in Fig. 2, it bears upon and is supported in the proper position by the pieces E of the bottom frame.

The arms B of the seat A are each provided with the curved or bayonet slots 1) and screweyes I), the former to receive the lugs 75, proj ecting from the sides of the table, the said eyes being engaged bypins m, attached to the ends of extensions n of the table K, the said pins having coiled springs 0, the pressure of which against the serew-eyes tends to lock thelugs k in the bayonetslots b, as will be readily understood.

I claim 1. In a combined high chair and childs carriage, a seat and an attached seat-frame provided with wheels and a bottom frame composed of connected pieces D E, pivoted to the seat-frame in the line of the axis of the front wheels combined with the toggle-jointed arms, substantially as described, pivoted to the back of the seat-frame and to the bottom frame, and with the stop to limit the movement of the toggle, as and for the purpose set forth.

2. The combination, in a combined high chair and childs carriage, with a seat and an H attached seat-frame provided with front and back wheels, of the bottom frame pivoted to the said frame in ihe line of the axis of the .front wheels and provided with a cross-piece, f, at a point beyond its pivotal connection, and a toggle connected with the rear end of the seat-frame and with the bottom frame and provided with stops to limit the movement of the toggle in one'direction, substantially as set forth.

3. The combination, with the seat provided with the pivoted handle J, and an attached seat-frame provided with front and back wheels, of the bottom frame pivoted to the seatframe and the toggle connected with the rear of the seat and bottom frames, whereby the bottom frame serves as asupport for the handle, substantial-1y as specified.

4. The combination, with the seat provided with the arm-supports and arms, the said arms being provided with slots and screw-eyes, as specified, of the table K, having the lugs and the extensions provided with pins and coiled springs, substantially as and for the purpose set forth.

In testimony whereofl have signed my name to this specification in the presence or two subscribing witnesses.

FRANK F. PARKER. Witnesses:
