IMPROVEMENT IN COMBINED CHAIRS AI\ID STEP-LADISER'S. i

The Schedule referred to in these Letters Patent and making part of the same.

T0 all whom Ait 'may concern.'

Be it known that we, IB JBGENSON and RAS- MUS OLsON,`ot' Racine, in the county of Racine and in the State of \Visconsin, have invented a new and useful Combined Chair and Step-Ladder; and we do hereby declare that the following is a full, clear, and exact description oi' the saine, ret'erenceibeing `had to theaccompanying drawing making a part of' this specification, in which- Figure l is a side elevation of a combined chair and step-ladder, showing the invention employed as a chair;

Figure 2l is a side view, showing one part of 'the chair reversed and the top part Ot' thebacli of the chair resting on the ground. In this positio'n a iiight of steps is formed.V

. Figure 3 is a side view of one detached part of the chair; and

l Figure 4 is a side view of the other part of the chair, with the back removed.

' Figure 5 is a Side view of a step, which may be attached to or detachedV from the hind legs of the chair.

Figure 6 is a side view of the adjustable step, and represented as raised, forming an additional step.

The same letters of reference in the several iigures denote identical parts.

The nature of our invention consists in a combined chair and step-ladder, consisting of two parts, which may be detached from each other and employed independently of each other as step-ladders or stools; or both parts may be combined, forming either a chair or step-ladder, according to the pleasure of the owner.

Vhen the inventionis employed asa step-ladder the number of steps may be increased by one o r more additional ones.

A is the frame of one part of the chair, which remains on the Hoor in its original position when the other part A1 is reversed.

The parts A and A1 are connected together by means of two bars or rods, B B, which are permanently secured (one on each side) to the outer edges of the seat on the part A1, but only attached to the edges of the seat of the part A by a screw or bolt, A, which serves as a pivot on which the part A1 may turn.

O1, C2, G3, and C are steps, which are constructed and so arranged that they may fit into each other when the chair is folded together.

Hooks, G G, are provided near the lower stepon the part A1, which fastcns the parts A and Al together when they forma chair, so that the chair may be carried about without any difficulty.

As it may become desirable to increase the num- `ber of steps when'the invention is employed as a the construction more complicated, expensive, and

awkward to move about, the additional step is constructed and arranged in suoli a manner thatit may be lowered and raised at pleasure, as shown in figs. 4

and 5.

The step G5 is, at each end, attached to,1 bars oi i metal or any other suitable material, which rest against the inner sides of the legs of the chair.

The bars D arc provided with slots, which, at their lower ends, terminate in a curvature of sntiieient size to admit the guides or bolts E E.

Fig. 5 represents the additional step when lowered down ina. level with the step O, forming one half Oi' said step. 4

Two bolts or stops are inserted in each slot of the bars D, where they serve as guides when the bars arev raised or lowered.

Said bolts are fastened to the inner sidesof the hind legs of the chair and` placed at short intervals, i

one above the other.

The lower bolt 'E' serves also as a rest or support for the bar D, and enters into the curvature of the slot-when the step is raised.

Fig. 6 shows the additional step C5 'thus raised and supported, and in order to prevent the step from sliding down when a heavy weight is placed on it, the curvature of the slot extends upwardv for some little distance.

When the bolt or support E has entered the curvature in the slot the bar D cannot slide down before it has been raised sufficiently to let the bolt E' pass out of the curvature.

VThe back Ot` the chair 'is hinged to the seat and supported by arms which may be detached, if desired.

and Al from each other, and employ them as separate step-ladders, it may easily be accomplished hy detaching the back of the chair and removing the bolt or screw A2, which connects the bar B to the p art A.

The combined chair and step-ladder may be handsomely tted ont, but the main object of' this invention is to furnish a household article which combines Should it become desirable to detach the parts A i a neat appearance with simplioityndurability, and cheapness. y

Having thus described our invention,

What We claim, and desire to secure by'Letters illl StrepCs, the bars D D provided wilghrslots in which are inserted'the bolts E E secnred to the inner ysides of the hind legs of a chair, substantially as and for the purpose set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
