ATENT ROCKING-CHAIR.

SPECIFIGATIOR' forming part of Letters Patent No. 540,87'7, dated June 1 1, 1 895.

Application filed January 9, 189 5. $eria1N0.534,367. (No model) like letters and numerals on the drawings representing like parts.

This invention has for its object to provide a rocking chair with springs, and supports therefor which in addition to providing points of attachment for the springs,'restrain the rocker from moving along the rockerframe, or base supporting it.

In accordance with this invention the rocker-frame or base which supports the rocker,

comprises two parallel bars, preferably grooved at their upperrsides to receive the rockers, said bars resting upon suitable supports, and the spring supports, two preferably being employed, each comprise two members,

the lower one being formed integral with or secured to therocker frame, as to the rockersupportiug bar for instance, and the upper one being pivotally connected to the rockerframe, as to the rocker-supporting bar for instance, and the forward end of the upper member is loosely connected to the rocker, so that that as the rocker rocks, the upper member will be moved up and down on its pivot. The upper end of the spring is connected to the upper member, and the lower end to the lower member, and in order that said spring may be adjusted toward and from the pivot of the spring support, each member is provided with two or more points of attachment.

Figure 1 shows in vertical section a rockingchair embodying this invention; Fig. 2, a plan view of the base provided with rocker-supporting bars and supports or connections for the springs; Fig. 3, a rear end view of the rocker-supportingbars and parts connected therewith; Fig. 4, a modified form of spring-support, to be referred to; Fig. 5, a vertical section of a rocking-chair, showing another modified form of spring-support; Figs. 6 and 7, under side and plan views of the spring-support shown in Fig. 5.

The base of the chair consists essentially of the side pieces a, a, and tranverse connecting pieces a, a. Bolted to said cross pieces a,

a, are two metallic rocker'supporting bars I), 1), arranged in parallelism with and adjacent to the side pieces a, the heads of the bolts by means of which they are secured to the bars being countersunk in the bars. A rockerframe is thus formed.

Each metallic rocker supporting bar I) has cast integral with it a slotted or other car or lo I) located near its rear end, to which is pivotally connected a curved or bent arm 0, said arm extending forward, and being loosely connected at its forward end with the rocker d, or it may be the chair body, by means of a link 0'. The arm 0 has formed in or along its under side two lugs 2, 3, side by side, to provide separate points of attachment for the upper end of the spring e, one point, as 3,being nearer the pivotal connection of the arm than the other. This arm 0 constitutes the upper member of the spring support. A lug b is also cast integral with each metallic rocker-supporting bar Z), which projects downwardly for a short distance, then at right angles in a direction toward the front of the chair, as shown in Fig. 1. The lug b is formed with two notches 4, 5, located beneath the lugs 2, 3, to provide separate points of attachment for the lower end of the spring e, more or less distant from thepivotal connection of the arm '0. This lug 19 formed integral with or attached to the rocker-frame, as to the rocker-supporting bar for instance, constitutes the lower memberof the spring-support.

The upper side of each metallic rocker-supporting bar b is grooved to receive the rockers cl, and in the present case the rockers are circular in cross section, and the grooves in the bars correspondingly shaped. There are material advantages gained by employing me tallic rocker-supporting bars, grooved to receive the rockers, as for instance suppose these bars were made of wood they must be made of wide stock to support the rocker, and

if grooved to receive a circular rocker the edges are liable to split off if the rockers should swerve ever so little, and they must also be made of considerable thickness to provide a good and efficient support for the pivotal connection of the arm 0; and for the lug b or its equivalent, and as a result. a bar with these parts attached to it presents a very clumsy and otherwise unsightly appearance.

By referring to Fig. 4, the upper part or member of the spring-support is the same as shown in Figs. 1 to 3, but the lower part or member is represented as two separate lugs or hooks c 0 formed integral with the rockersupporting bar, at points directly below the, lugs 2,3, and serving as points of attachmentf i and rocker-frame, and adjustable toward and for the lower end of the spring.

Referring to Figs. 5 to 7, the upper part or member 0 of the spring-support is the same as shown in Fig. Land the lower part consists of a plate or bar, cast or otherwise formed with a hookf, notched at. 4, 5, to .receive the lower end of the springe, an ear f by means of which it is secured to the under side of the-'rocker-supportingbar, and an ear f extending upwardly to which the upper part c is pivoted. This lower part is placed against the inner sideof the rocker-frame or bar, and'secured by ascrewipassing through said ear f and another screw passing through the plate into the side of the frame. The

rocker-frame is made of Wood and its :rocker- 'supportin g bars have fiat tops.

These modificationscome within the spirit andscope of myinvention.

1. In a rocking chair, thecombination of a rocker and rocker-frame, .a spring-support.

comprising an upper partipivotally connected at its rear end to a fixedpointon the rocker frame,'and loosely connected at its front end with the rocker, a lower part on the rockerframe, thespring e connecting the parts, the said spring-support restraining the rocker from movingalong therocker-frame, substantiallyas described.

2. In arocking chair, the combinatiom of a rocker and rocker frame, a spring-support comprising an :upper part having =lugs 2,3, at a point between its ends, and pivotallyconnected at its rear end to a fixed point on the rocker frame, and loosely connected at its front end with the rocker, and a spring d, the upper end of which is attached to one of the hooks on the upper part, and the lower end of which is attached to a fixed point on the rocker frame, directly beneath its upper end attachment, substantially as described.

In a rocking chair, the combination of a rocker and rocker-frame, arm 0 pivotally connected at its rear end to the rocker frame and loosely connected at its front end to the rocker, spring e interposed bet ween the rocker from the pivotal connection of said arm a, substantially asdescribed.

4. In a rocking-chair, two metallic rockersnpportingrbarsb,b,having cast integral therewith ears I), and spring-supporting arms a,

, pivotedattheir rear ends to said ears and connected loosely at their front ends to the rockers of the chair, substantially as described.

the upper ends'of .the springs c, substantially as described.

6. .In a rocking chair, two metallic rockersupporting bars 11, b grooved at the upper sides, and having cast integral therewith ears '1), and lugs 11?, spring-supporting arms 0, pivoted to the ears, and sprtn gs e connecting said arms with the lugs b substantially as described.

:In testimony whereof I have signed my :name to this specification inthe presence of twosubscribing witnesses.
