ROCKlN G-CHAIR'FAN.

SPECIFICATION forming part of Letters Patent No. 513,809, dated January 30, 1894.

Application filed November 2, 1893. Serial No. 489,779. (No model.)

To LtZZ whom it may concern.-

Be it known that we, EMIL METHKE and HENRY SCHWALBE, subjects of the King of Saxony, (having resided one year last past in the United States and declared our intention of becoming citizens thereof,) residing in the cityandcouuty of Philadelphia, State of Pen nsylvania, have invented a new and useful Improvement in Rocking-Chair Fans, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of a fan attachment to a rocking chair, formed of parts whereby the fans may be readily operated, as will be hereinafter set forth.

It also consists of the construction of the springs of the form of shoes, and coupling them in such manner that they possess great resiliency, operate comparatively noiseless, and are steadied in their motions.

It also consists in mounting the fans on rock shafts, and connecting the same therewith in such manner that they may be set at various angles, and folded when not required for use.

Figure 1 represents a perspective view of a shoe embodying our invention. Fig. '2 represents a side elevation of a detached portion thereof. .Fig. 3 represents a horizontal section thereof, on an enlarged scale, one of the fans being shown folded, in dotted lines.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings: A designates a rocking chair, which excepting the features of our invention applied thereto is of usual construction.

Connected with the rockers B are springs C, which in their normal condition rest on the floor, so that by the rocking of the chair, rising and falling motions are imparted to said springs.

D designates a vertically-arranged slide, which is fitted in a guide E on the rear of the seat of the chair, and having connected with its upper end the cross head F, to which are pivoted the links G, whose upper ends are pivoted to the toggle levers H, one limb of each of which is mounted on the back of the chair, and the other limb is pivoted to a crank arm J, on a vertical rock shaft K. The shafts K are in opposite sides of the back of the chair, and provided with journals which enter ears M on said back, whereby the shaft-s are mounted in position on the chair.

N designates fans which are provided with sleeves P, the latter being freely fitted on the shafts K, and connected therewith by pins Q, which project from said shafts and enter slots or recesses R in the sleeves. It will now be seen that when motion is im parted to the slide D by means of the springs O, the same is communicated to the links G, the toggle levers H, the crank arm J, and the rock shafts K, whereby the fans are operated, especially for the occupant of the chair, the eifect of which is evident. When the slide D is raised to a sufficient height to clear the springs O of the floor, the fans are rendered inoperative, and

the rocking of the chair may be efiected without action of the fans. In this'case, the slide is retained in elevated position by means of the pin R, which is passed through an open- .ing in said slide above the guide E, thus controlling the descent of the slide.

Owing to the slots R, the fans may be raised and set at different angles, and when not required for use, folded on the back of the chair, as shown in Fig. 3, the fans then being lowered and the respective slots receiving the pins Q, so that the fans retain their adjustment or inoperative positions.

In order to cause the springs C to possess great resiliency and work comparatively noiseless, the same are curved in the form of shoes, and attached at one end tothe rockers, and left free at their other ends. The springs are coupled by a cross piece S, which serves to steady the same and prevent lateral play, also providing means for the attachment of the slide D to the springs. 1

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- V 1. A rocking chair having a fan attachment consisting of a spring connected with the rockers and movable on the floor, a vertical slide on the chair connected with said spring, a toggle lever mounted on the chair, a link pivotally attached to said slide and lever, a rock shaft on the chair, and a crank arm on said shaft attached to said lever, the fan being connected with said shaft, said parts being combined substantially as described.

2. In a fan attachment to a rocking chair, 5 the operating springs adapted to rest on the floor, and formed of elastic shoes, and a cross piece connecting said shoes, the slide of the attachment being secured to said cross piece, the parts namedbeing combined substantially :e as described.

3. A rock shaft mounted on the chair, and

provided with a projecting pin, and a fan having a sleeve freely fitted on said shaft and formed with slots to receive said pin, whereby the fan is connected with the shaft and may 15 be angularly adjusted and folded, substantially as described.
