FAN ATTACHMENT FOR CHAIRS, 84C

SPECIFICATION forming part of Letters Patent No. 421,330, dated February 11, 1890.

' Application filed September 6, 1888- Serial No. 284,733. (No model To all whom it 12mg concern:

Be it known that I, ROBERT TAGGART, of Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Fan Attachments for Chairs, the; and I do hereby declare that the following is a full, clear, and exact descrip tion of the inventiomwhich will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the form part of this specification. I

My invention relates to an improved. attachment for chairs, rockers, the.

The object of the invention is to produce an improved article of the class mentioned which can be readily and easily attached to or detached from a chair, whether a rockingchair or not, or can be applied to a cradle, and which shall be simple in construction and effective in operation, and composed of a minimum number of strong and durable parts.

The invention consists in certain novel features of construction and combinations of parts, more fully described hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a perspective view of a chair with my invention attached. Fig. 2 is a detail elevation of the device, portions being broken away. Fig. 3 is a detail view of the upper portion of the casing, in which the operatingrod works, the casing being partially broken away to show the gearing connecting the fanshaft and reciprocating; operating-rod. Fig. 4 is an elevation of a portion of the fan-holder, showing the clamp by which it holds the fan. Fig. 5 are detail views of clamps, by which the device is rigidly and detachably secured to a chair.

As shown, the device comprises a reciprocating spring-actuated rod provided with a suitable casing adapted to be clamped-to a chair, so that the rod will project below the same, a fan or rocleshaft connected with and rocked by the reciprocating rod, and a fanholder adj ustably secured to the fan shaft and provided with a clamp to hold a fan.

In the drawings, the reference-letter (I, indi cates a suitable supporting and. inclosing tube or casing, preferably composed of a length or section of gas-pipe open atits lower end and provided upon its upper end with anenlarged portion Z), provided with a side opening, or,

preferably, a T section or coupling. v A rod 0 extends longitudinally through the casing and T and projects a suitable distance below the lower end of the same, while its upper end is confined and reciprocates in a suitable slot in the upper closed end of the T. A coiled spring 61 embraces the reciprocating rod 0 and at its upper end bears against a stationary stop 6, while its lower end bears against a stop f, secured to and moving with the rod 0. A stop g extends from the casing a to engage stop f and limit the downward movement of the same.

The lower end of the rod 0 which projects below the casing is provided with a nut t', if desired. It will be observed. that the spring is constantly tending to force the rod 0 downwardly, with its end projecting its full extent out of and below the casing.

The upper portion of therod c in the upper portion or T of the casing is provided witha lateral bend, as shown,having a rack or teeth j upon its inner longitudinal face. A fanshaft It extends transversely through and is j ournaled at one end in the upper portion or T of the casing, and is also journaled or ro tates in bushing Z, placed in the lateralopening of the T. The inner end of the shaft eX tends through the bend of rod 0, and a pinion m is rigidly mounted on the shaft and meshes with rack j. The shaft 7t extends laterally a suitable distance from the rod 0, at right an gles to the same, and uponits outer free end is provided with an adj ustable fan-holder c011- sisting, preferably, of a flat barn, of metal or other material, provided with a longitudinal slot 0, whereby it is adj ustably. secured to the shaft by means of a clamp comprising a thumb screw 19, extending through the slot and screwing into the fan-shaft, and provided with a washer (1, between the head of the screw and the outer face of the bar n. Upon its free end the bar at of the fan-holder is provided with a clamp consisting of a rigid jaw r and a movable spring-jaw s, movably secured to the same by means of pins 25 t and a belt at, extending through the arm a, rigid jaw, and movable jaw, and provided upon one end with a nut and a coiled spring 1), interposed between said nut and the outer face of the movable jaw, whereby the same is constantly and yieldingly held bearing against the rigid jaw, as clearly shown. Either jaw of the clamp is provided with a set-screw h, extending through the same to more securely hold the fan w in the clamp.

Two forms of clamp by which the device can be secured to a chair are shown in Fig. 5,

I and consist of rigid jaws to receive a portion of the chair and aset-screw to clamp the same in the jaws, and the rigid jaws are provided with a ring or circular aperture to receive the casing a, which is clamped in the same by a set-screw. If desired, the ring to receive'the casing a can be mounted upon a'screw working through the rigid jaws, as shownat 0c in Fig. 5. By this means the clamp will admit of more varied adjustment.

The shaft can be provided with a joint y to allow the parts to swingin one plane, and thus allow the fan to be thrown up and out of the way, so as not to inconvenience a per son getting in or out of the chair. A sliding sleeve z is located in the shaft to slip over the joint y'and hold the shaft rigid, when desired. I

The device is secured to a chair, 850., by

the clamp shown in Fig. 5, with the lower end of the rod 0 projecting a suitable distance be-' low the bottom of the rocker or a leg of the chair, and it is evident that by rocking when the chair comes forward the end of the rod o strikes thefioor, forcing the rod up into the casing against the tension of the spring and rocking the fan-shaft and fan in one direction, and then when the chair moves back the spring forces the reciprocating rod to its norinal position,rocking the fan and shaft in the opposite direction. .It is a very quick and prompt motion, and the device is exceedingly neat and tasty in appearance, and there is not Having thus fully described'my invention,

a complication of parts to get out of order.

What I claim, and desire to secure by Letters Patent, is'

1. In a fan attachment for chairs, the combination, with a rock-shaft, a standard to support the same, and means, substantially as described, to operate the same, of a laterally-extending longitudinal slotted plate or bar adjustably secured to the free end of said shaft, a clamp securing said plate to the shaft, whereinclination or longitudinal adjustment, and a fan-clamp on the lower free end of said plate, composed of a jaw rigidly secured to the plate, and a movable jaw loosely secured to the same and provided with a spring to hold it in engagement with the rigid jaw,'subs'tan tially as described.

2. A fanattachmeht for chairs, consisting of a tubular casing provided with adjustable clamps to secure it in position extending .above a chair, a hollow head on thejupper end of the casing, having'a guide-opening in its top, and a side bearing-openingprovided with a bushing, areciproc'able operating-rod extending below the casing and at its upper end into saidguide-opening, a spring to force the rod down, a lateral bend in the rod opposite the bearing-opening of said head, provided with a rack on its inner side, a horizon-.
