Application flied A gust 31, 1899.
To (0Z5 1071,0122. it may concern:
Be it known that I, JOHN W. Bow ERS, a citi- Zen of the United States,residing at Rockland, in the county of Plymouth and State of Mas-. saohusetts, have invented certain Improvements in Platform Rocking-Chairs, of which the following is a specification.
My invention relates to that class of rocking-chairs known as platform-rockers, and hasfor its object to simplify the construction and reduce the number of parts.
To this end my invention consists in a rock-' ing-chair having a base or stationary portion,
a seat provided with a centrally arranged rockersupported by and moving on said base, and means for maintaining said rocker and seat in an upright position and preventing lateral movementof the same in either direc-. tion, as hereinafter more fully set forth.
My invention also consists in certain novel tion, as hereinafter described and specifically claimed.
In the accompanying drawings, Figure 1 is a side elevation of a platform rocking-chair embodying my invention. Fig. 2 is a central vertical section of the same. Fig. 3 is avertical section on the line 3 3 of Fig. 2. Fig.4 is ahorizontal section on the line 4 4 of Fig. 3.
In the drawings, A represents the base or platform,whiohis preferably composed of two horizontal bars put together in the form of a cross, as shown in Fig. 4, thereby occupying the minimum of floor-space and at the same time affording a firm support for the chair.
From the base A rise two side pieces B B, each provided on the outer side with two solid uprights a a, having strengthening side pieces rights is secured, by means of vertical bolts 0 c, a transverse metal bar 0, at the ends of which are formed bearings 61 d for a horizontal rock-shaft D, to which is firmly secured a cylinder f, within which slides a piston or plunger 9, the upper-end of which is pivoted at 10 between two ears h 71, formed integral with a metal chair-supporting frame or spider E, to the arms of which is securely fastened the chair-seat G, which may be of any desired shape or construction.
H is a rocker which is centrally arranged with respect to the chair-seat G, as shown in Serial No. 729,114. (Nomodel'.)
Fig. 3, and is connected with its supporting frame or spider E by means of two slightlyconverging bars 7c 7r, which are securely fastened to the said rocker and spider by long bolts m m, which extend through the rocker, the bars, and the spider, and are provided at their upper ends with nuts it, the several parts being thus rigidly braced and held together as required.
The rocker H is maintained in its proper position on the base A by means of a flat k k, said buffer being adapted to contact with the rounded corners of the barC, which form stops to limit the rocking movement of the chair-seat in either direction.
During the rocking of the chair-seat forward and backward the piston g slides up and down within the cylinder f, the two form ing anextensible guiding brace or stay for preventing any possible lateral movement of the chair-seat in either direction, the cylinder receiving the lateral strain, which is in turn transmitted to the horizontal shaft D and its bearings, which thus resist any tendency of the chair-seat to tip to one side or the other and prevent any possibility of the contact of the rocker bars 7.: 7a with the side pieces B B.
It is obvious that the positions of the members of the extensible guidebrace or stay may be reversed, if desired-that is, the cylinder may be. attached to the spider E and the piston to the rock-shaft D without departing from the spirit of my invention.
The narrow space between the side pieces B B is partially closed at the front and rear by strips r r, and it will be seen that the rocker is protected and concealed from view by said side pieces and strips, which form a narrow box or casing therefor, whereby the feet and hands are efiectually prevented from coming into contact with and being injured by the rocker, an event of frequent occur rence with the ordinary platform rockingchair in common use.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. A rocking-chair comprising a base or sta tionary portion, a seat provided with a centrally-arranged rocker supported by and moving on said base, and means for maintaining said rocker and seat in an upright position and preventing lateral movement thereof in either direction, substantially as described.
2. In a rocking-chair, the combination-with a base or stationary portion, of a seat pro vided with a centrally-arrangedrocker sup ported by and moving on said base, and-a jointed extensible brace or stay connected having side pieces or uprights, a chair-seat having a central rocker, upright bars connecting said rocker and seat and moving between said side pieces, a rock-shaft, an oscillating cylinder mounted on said rock-shaft, bearings for said rock-shaft secured to said uprights, and a piston fitting Within said cylinder and rigidly secured to the seat-supporting frame or seat, said cylinder and piston forming an extensible brace or stay to prevent lateral movement of the seat and rocker, substantially as described.
' 5. In a rocking-chair, a base having side pieces risingltherefrom and forming a casing for the rocker, combined with a seat having a centrally-arranged rocker, upright bars connecting said rocker and seat and swinging between said side pieces, an elastic bufier for limiting the movement of the rockerand-seat in either direction, and a jointed extensible brace or stay connected with the seat and base to prevent lateral movement of the seat in either direction, substantially as described.
Witnessmyhand this 28th day of August, A. D. 1899.
