CHAIE.

Specifieation of Letters Patent No. 9,449, dated December 7, 1852.

first, in elevating and depressing the leg rest which is hinged to the front edge of the seat and connected by a link to a lever the fulcrum of which is connected with the under side of the seat, and the lever operated by the standing frame of the chair, which lever is constructed so as to be locked by another lever o perated by the person occupying the chair, and which enables him without leaving his seat to release the first leVer and adjust the inclination of the back and leg rest to such a position as pleases him, and then to lock or fasten the chair in that position; thus enabling him to change the inclination of the back seat and leg rest at pleasure, and with facility and to fasten them in such position as he desires without rising from his seat. Second in making notches in the back side of the slide that holds the head rest and making the aperture it slides in so large that it may be moved forward so as to release it from the plate that catches into the notches, and raised or lowered, and pressed back so that the plate upon the back side of the aperture will catch into a notch and hold it at the height required.

'To enable others skilled in the art to make and use my invention I will proceed to descrbe its Construction and operation referring to the beforementioned drawings of which,

Figure 1, is a side elevation. Fig. 2, is a. representation of the stands, levers, etc., as seen from the bottom.

The same letters indicate like parts in each of the figures.

A is a scroll stand connected to a similar one by the girt B and rounds C C represented by dotted lines. The standard D is fastened to the stand A, and a similar one upon the opposite side of the chair, these standards support the pivots of the bottom of the chair one of which is represented at E. The bottom F may be made of such a form and size as may be desirable with a back and arms (if there are any) t'astened in the usual manner or otherwise. The front edge of the bottom or seat F is beveled back upon the underside, and has the leg rest G hinged to it as represented at H so as to Vibrate freely and may be made of a frame of proper form and size stuii'ed as represented or otherwise. There are two stands I and J fastened to the underside of the seat which support the shaft K, which shaft is fastened into the lever L and forms its fulcrum. The lever L is made in the form represented and the long arm is jointed at M to the link N, which connects it to the stand O, to which it is also jointed, and the stand O is fastened to the underside of the leg rest G which rest has a recess P, in its underside (shown by dotted lines in Fig. 1,) which receives the link N and the end of the leVer L when the rest G is brought to a perpendicular position. The stand J is made a little longer than the other and has a score for the leVer Q which Vibrates upon a pin passing through it for that purpose. The stand I is represented as broken off so as to show the notches in the lever L into which the end of the lever Q catches and retains the chair or back, seat, and leg rest in the required position. A side elevation of the lever Q is represented in Fig. 3. It has a hole in it at S for the cord T which passes through it and up through a staple under the arm of the chair. The stand U is tastened to the girt B and has the rod V passing across from one part to the other, and the curved prongs W W of the lever L pass each side of the rod V 'so as to go-Vern the elevation and depression of the lever L and the leg rest G. The prongs W `W may be straight or curved more or less so at to elevate and depress the leg rest as may be desired.

The back of the chair X may be made in the usual manner or otherwise and fastened to the seat F. In the upper part of the back X there is a caVity a for the notched slide b. The back is represented as broken out to show the cavity a. The metal plate c at the top of the back projects partly over the cavity a and fits the notches in slide b; so that as the head rest (Z is moved forward it may be raised or lowered as required and then pressed back so that the metal plate c will catch one of the notches in the slide b and retain it until it is moved forward to be readjusted.

The dotted lines e, f, g, 71, and z', represent the outlines of the stufifed coverng of the chair.

This chair may be adjusted by the person sitting in it in the following manner. Suppose the seat to be horizontal and the back and leg rest nearly perpendicular and the end of the lever Q, being in the first notch in the lever L holds the several parts permanently in the position above mentioned. But should the occupant Wish to recline he pulls the cord T, raising the lever Q, releasing the lever L; then by leaning against the back it Will recline and carry the fulcrum of the lever L forward and raise the legrest, When he may slack the cord T and drop the lever Q so as to catch in to the second, or some other notch in the lever L and hold the several parts in a position more or less inclined as the occupant may desre; and whenever he Wshes to resume an upright position, he has only to pull the cord and throw his Weight upon the front part of the seat When it Will return to a horizontal position and depress the leg rest and elevate the back to its former position. Then by slacking the cord the lever catches into the first notch and fastens the several parts in the position first mentioned.

I contemplate that my inprovements may be applied to the seats of railroad cars, sofas and other articles for sitting and reclining, Also that there may be several plates arranged to catch into the notches in the rack of the head rest. And to use such devices for looking the chair in the required position as may be most desirable.

What I claim as my invention in the above described chair and desire to secure by Letters Patent is,

Operating the leg rest from the motion of the seat and back by means of the lever L and rod V or their equivalent.

In testimony Whereof, I have hereunto signed my nane before two subscribing Witnesses.

LAURENCE McLAREN, JAMES T. HADDOCK.
