Letters Patent No. 79,656, .dated July 7, 1868.

l 'IMPEOVED EocKINe-GEAIE.

KNOW ALL MEN EY THESE PRESENTS:

Thatl', EDsoN HARTWELL, of Hubbardstomin the countJy of Worcester, and Comnionwealth of Massachusetts, have invented .certain new and useful Improvements in Rocking-Chairs; and I do hereby declare that the following is a full, elear, and ex-.act descriptionof the same, reference being had tothe accompanying drawings, i

forming a part of this specification, in lwhich-- -Figure 1 represents ax'side view of my'improved chair,

Figure 2 represents 'alongitudinal section through the side piece of the chair-seat and frame, and

Figure 3 represents a crossfsection through piece D, andparts connected therewith.

To enable those skilledfin the artto which my invention belongs to make and use the same, I will proceed to describe it more in detail. l i

In the drawings, the chair-seat A, to which the back C is attached, is supported upon the tops of the bent or curved side pieces D',one"o'nf eachside of the chair, by means of two standards E, one on each side of the chair. l Y* i v The standards E are formed at their tops in T-shape, the horizontal projection being fastened to the under sides of the seat-frame, while' their lower ends are made with curved seats a, and with two curved projections or horns, b ,to tit in corresponding slots c c in the inner plates I", which are also provided with teats or projections d, and .upon which the curved seats a rest. i l

The plates F are fastened in recesses out in the tops of the bent or curved side pieces D.

pon the inner sides of the standards E rise ears e; which afford inner supports or guides for the standards.-

After the lower ends of the standards E have been'slipped into place, as indicated in the drawings, outer plates G, having earsf, are secured in slots made -in the tops-of the pieces D, so as to t up close to the outer edges of the plates F, wherebyvthe earsfaord outer supports for the standards E.

To; the upper rounds of the frame-of 4the chair ,is fastened a piece, I, running from front to back, and a corresponding piece, J, is fastened to the under side of the seat-frame A. p

Spiral springs'g g, having adjusting-nuts, are 4combined with the pieces I and J, as fully set forth in my previous patent, and foi` the purposestherein clearly setforth. y a

Whenv the seat A. is rocked back and forth, the curved standard-seatsla roll upon theprojections d, while the curved projections b b on the standards prevent the latter froui being displaced from the plates F.

By makingthe pieces D inthve form shown, they'are niade to serve for back legs as well as top pieces for the chair-frame. i'

The motion ofthe scat back and forth, when supported as shown and described, is easy and very uniform, Again, there is no 'danger of a squealiing noise, as is the case when the seat is supported by pieces pivoted to tho seat-frame. i v V Having described' my improved rocking-chair, whatI claimf'therein asmew and of my invention, and desire to secure by Letters Patent, is

l'. The combination of the arms or standards E, having curved projections b b'with .the slotted plates F, substantially as and for the purposes set forth. 1'

2. The combination,\vith the lower ends of the standards E, of the'platesF and G, substantially as and for the purposes set forth.

The combination, with the seat-supports or standards E and chair-frame, of the curved pieces D, substantially as and for the'purposes set forth.

4. The combination of the scat A with the springs g g, standards E', and chair-fran1e', substantially as and. for 'the purposesset forth. i

EDSON HARTWELL.
