COMBINED CHAIR, STEP-LADDER, AND TRES'TLE.

. SPECIFICATION forming part of Letters Patent No. 739,395, dated September 22, 1903.

' Application filed January 20, 1903. Serial No. 139,761. (No model.)

T0 at whom it may concern:

Be it known that I, EDWARD J. DARLING, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in a Combined Chair, Step-Ladder, and Trestle; and I do hereby declare the following. to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertai-ns to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention comprises a combined chair, step-ladder, and trestle, the latter being particularly adapted to receive and support an ironing-board.

The object of the invention is to form a improved device of the kind stated adapted to a variety of uses and having certain advantages with respect to construction andvation.

Referring specifically to the drawings, 6 indicates the side bars, and 7 the steps, of the ladder. Two pairs of props are used in connection with this ladder, one pair being indicated at 8, which I will call the ladder props, and the other pair being indicated at 9, which I will call the chair props or sup- The latter are pivoted at their up porters. per ends at 9 to the side bars of the ladder, and the former-that is, the ladder-props 8- are pivoted at 8 to the chair-props 9.

The ladder-props have suitable cross bars or braces 8 ,an'd the chair props or supporters to the top bar 8", forming a swinging section which serves as a bucket-shelf when swung out, as shown Fig. 2, by engaging undor'a round 6", which extends. across between the the side bars of the ladder under the top step thereof.

j The chair-seat is composed of slats 10, which extend across between side framesll, which are pivoted at 11 to the side bars of the ladder at a proper height for the chair. The chair-seat is movable within or between the members of the props.

The side bars of the ladder have at the top and back edge thereof notches 6, which receive the topmost cross-bar 8", and at the bottom thereof notches 6 which receive the lowermost cross-bar 9". The seat-frames 11 have in the lower edge thereof notches 11 whichreceive one of the intermediate crossbars 9".

To adjust the device as a chair, as shown in Fig; 1,the top cross-bar of the ladder-props is engaged in the lower of the notches 6 and the seat is projected through between'the props and the parts locked-in position by engagement 'of, the intermediate bar 9 in the inner notches 11 To adjust the parts as a step-ladder,the topmost round of the ladder-props is engaged in the upper notches 6? and the bottom of the props swung out until the intermediate bar 93 engages the outer notches 11, forming a tie, whichprevents further spreading of the, props. The ladder may then be mounted in safety. l V V To form a trestle, as indicated in Fig. 3, the ladder-props are disconnected at the top and swungaround to engage the bottom crossbar 9 in one of the notches 6 and the ladder being turned to a horizontal position the props form cross-legs therefor. The series of notches 6" permit the trestle to be adjusted to various heights. The seat hangs idle between the props when the parts are adjusted as a trestle, except when the trestle is let down to the last notch to form a washbench, when the lower ends of the seat-frame reach the floor and help to support the bench. On the trestle so formed anironing-board 12 may belaid, and cleats (indicated in dotted lines 12 on the bottom of the ironing-board) enter between the steps and side bars of the ladder it a e and serve to prevent sliding of the board. The props are out to proper length to rest on the floor when the parts are adjusted to form a chair. This forms a stable and strong support for the chair. The device may be folded into very small compass by detaching the crossbar-s from the notches and folding the props, ladder, and seat to parallelism as near as may be.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination with a ladder, of two pair of props crossed and pivoted together, one pair being pivoted to the ladder and the other engageable with the ladder at either end thereof, and tie-bars joining the foot of the ladder and the props.

2. The combination with a ladder having side bars notched at both ends, of the props 9 and notched seat-frames 11 pivoted to the said bars, and the props 8 pivoted to the props 9, the latter having a cross-bar engageable in the notches of the seat-frames and the former having cross-bars engageable in the notches of the said side bars.

3. The combination with a ladder, of props therefor, a seat pivoted to the ladder and supported by the props,and a vertically-swinging shelf hinged to the props and sustained in horizontal position by engagement with the ladder, and forming when in vertical position a back for the seat, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD J. DARLING.
