SPECIFICATION forming part of Letters Patent No. 393,169, dated November 20, 1888.

Application filed July 20, 1888.

To aZZ whom it may concern.: v

Be it known that I, JOHN McGowan, of Quincy, in the county of Norfolk, State of Massachusetts, have invented a certain new' and useful Improvement in a Combination Chair and Step-Ladder, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of my improved chair; Fig. 2, a rear elevation of the same; Fig. 8, a like View showing the movable seat thrown back; and Fig. 4, a vertical transverse section taken on linew .r in Fig. 3, some of the parts being shown in side elevation.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of chairs which are particularly designed for the use of invalids; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a simpler,cheaper,and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation:

In the drawings, A represents the body proper ofthe chair; B, the movable seat, and C the seat proper.

The body proper consists, primarily, of the hind legs z, which are extended upward to form the back of the chair, said legs being connected by cross-pieces 15 and 25, a rung, 35,and at the bottom by a broad horizontallyarranged cross-piece, 45. (See Fig. 4.)

The arms v occupy the usual position,extend ing horizontally outward from the legs z, said arms being provided with cushions b and connected by the seat proper, C,which is provided with a circular opening, 55. (See Fig. 4.)

The seat B is iitted to rest on the seat proper, C, between the arms o, and cover the opening 55,*said seatB being provided at each forward corner with a pin, d, (see Fig. 3,) which pins, respectively, project into slots f, formed in the inner faces of the arms c, and

are designed to secure the seat B to the body when pushed back from the seat proper until Serial No. 5280.520. (No model.)

it rests in a vertical position on 'the crosspiece 45, as shown in Figs. 3 and 4.

A brace, g, projects centrally downward from each arm '0, and is connected with a leg, c, by a horizontal brace,A h, said horizontal braces being connected by a transversely-arranged step, i. (See Fig. 4.)

A supplemental body, D, is hinged at 7c to the forward ends of the arms c, said body consist-ing of side pieces, m, connected by a rung, p, (see Fig. 4,) and transverse steps 75 and 65,upon which the step t' and seatproper,

l, respectively rest when the parts are in the position shown in Fig. 4, the body then forming the front legs of the chair.

In the use of my improvement, 'when it is desired to employ the chair as an invalids chair, the seat B is pushed backward until it falls into a Vertical position, with its rear edge resting on the step 45, (see Figs. 3 and 4,) thus allowing the vseat proper, C, to be utilized, a vessel, P, having beenpreviously disposed on the step ,as shown in Figs. 2 and 4, the pins d sliding in the slot f and holding said seat in position.

When the device is employed as a step-lad` der, the body proper, A, is thrown over onto the supplemental body D, by means of the hinges k, until the topof the backof the chair and cross-brace 15 rest upon the door, as shown by the dotted lines in Fig. 1,thereby forming a stepladder or consecutive series of steps consisting of the steps 55 and 65, seat proper, C, and steps t' and 45.

Havingthus explained my invention,what I claim is- In a device of the character described, the combination ofthe body proper, A,having the seat proper, C, provided with the opening 55, the step 45, connecting the legs of said body, the step i, adapted to support a vessel,

l?, the seat B, provided with pins d, fitted to slide in groovesfin said body, and the supplemental body D, having the side pieces, m, and connected by steps 75 and 65,upon which the step and seat C are respectively adapted to rest when the device is used as a chair,said body D being hinged to the body proper, A, in such a manner as to form a step-ladder therewith when said body proper is inverted, substantially as specified.

Witnesses: JOHN MCGOWAN.
