JAMES E. EMERSON, OF TRENTON, NEW JERSEY.

Letters Patent No. 96,211, dated October 26, 1869.

IMPROVE-D BOOKING-CHAIR.

The Schedule referred to in these Letters Patent and making part of the same To'all whom it may concern:

Be it known that I, J AMES E. EMERSON, of rirentou, in the county of Mercer, and 'State of New Jersey, have invented certain new and useful Improvemonts in Rocking-Chairs; and I do hereby declare the following to be afnll, lear, and exact description of the same, reference being had to the accompanying drawings, making a part ot' this specilication, in which- Figure l represents a perspective view of the rocking-chairs' f Figure 2 represents a Vertical section through the same.

Similar letters of reference, where they occur in the separate figures, denote likeparts of the chair in both of=the drawings.

lily invention relates `to that kind of rocking-chair in which thc upper or seat-portion rocks upon the stationary under or supporting-portion, and 'of which there are many forms; and

M y invention consists in the' devices by which the seat and basefare united, and on which the seat-portion rocks.-

And it .further consists in the use of pivot-points @and steps, for the seat to rock 1upon, which steps may also serve for oil-boxes, if oiling should be found necessary. i

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

A represents the stationary under portion of the chair, which Vmay be constructed in any of the usual well-known and substantial ways, and which I prefer to make rounded or circling on top, so that a circular concave seat will tit and move over it, the joint hetween the two heilig covered by a moulding, a, which prevents theclothes of the user from being` caught therein, or trom pinching the iingers.

The uppe` portion B of the chair, which consists of the seat b, arm-supports c c, and back d, may be made, and upholstered, if so desired, in any of the usual well-known ways, the side-pieces being, howere curved out, so as to snugly tit over the rounded part of the stand or stationary under portion.

On the rail or rung-pieces of the under stationary portion A, there `are' arranged steps, e e, which are cast with depressions or recesses in them, as shown by the dotted lines thereon, which form boxes, and in which the projecting points on the ends of the V or U-shaped supports G C, that are fastened to the upper or seat-portion B of the chair, enter and are supported, and upon which points, like the knife-edge ofa scale-beam, the seat-portion rocks.

In the supports or braces C are made circular slots, ff, through which a screw, stud, or pin, c', is passed into the plate that margins the steps, which connection admits of therocking of the seat-portion upon the points in the steps, and without a pivot-pin to work on, and still imite the upper and under portions, so that the chair may be moved about without the two parts separatino'.

Should it become necessary at any time to oil the hearing-points ou which theJ seat rocks, it may be done without liability of oiling`or' soiling the carpet or door, jas the steps are boxes capable ot' holding a. drop or more of oil withoutl allowing it to escape.

From the upper cross-piece I) of the stationary portion A, a coiled spring, E, extends to and bearsagainst the front piece Foi' the seat-portion, the reaction of which spring moves or helps to move the upper portion in one direction, whilst its compression prevents the seat from going too far, or with a jar, in the other direction. i

rDhis spring may extend from Dto the rear piece G, and serve the same purpose, or there may be two springs. one front and the other back, but one will be found to he enough.

lf the chair is required for a'stationary or a reclining-chair, it may be'made either by means of a springholt, an., with a thumb-nut head, n, which will take into any one of a series of holes,o o o, in the seatportion, and there hold it firmly to the stationary under portion.

The bolt passes through a catch-piece, r, that has recesses or notches s in it, so that the bolt in being turned will draw out and be caught and held out, when used as a rocking-chair, and can be turned further, when it will shoot into one of the holes o, and then hold it rigid and in an inclined position, when so desired.

Having thus fully described my invention,

\Vhat I claim therein asinew, and desire to secure by Letters Patent, is v s The combination ot' the pivot-pieces -or supports C with the steps c, for forming a rocking connection between the upper and under portions of the chair, as described and represented.

Also, the combination of the pivot-pieces, steps, and spring, with the oscillating seat and stationary under portion, as and for the purpose herein described and represented.

Also, in combination with the pivot-pieces and steps, the concentric slot and set-screw, for admit-ting ofthe rocking mot-ion of the upper upon the under portion, without allowing them to separate` when being lifted or carried, as set forth.

J. E. EMERSON.
