FAN ATTACHMENT FOR ROCKINGCHAIRS.

SPECIFICATION forming part of Letters Patent No. 544,421, dated August 18, 1895.

Application filed November 12, 1894. Serial No. 5281555- (NO model.)

To all whom may concern:

Beit known that I, JOSEPH S. URBAN, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have inventedcertain new and useful Improvements in Fan Attachments for Rocking-Chairs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others ro skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Flgure l is a side elevation showing the invention as applied to a chair. Fig. 2 isa vertical section showing the invention. Fig. 3 is a detail view of one of the attachment-clips.

This invention has relation to certain new zo and useful improvements in fan devices for rocking-chairs, the object being to provide a simple device of this character which can be readily applied to an ordinary rocking-chair and which is adapted vto give the fans an alternate rotation as the chair is rocked; and

the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claim.

3o Referring to the accompanying drawings, the letter A designates a common form of rocking-chair, to which I have shown the invention applied.

B designates an elongated tubular casing,

which is supported in vertical relation to the chair by means of plates or brackets C O clipped tothe body of the chair, as shown, the plates or brackets having each a clip c which embraces said casing. Extending 4o through said casing and projecting beyond both ends thereof is a rod D, whose lower end is secured in a tubular sleeve G, arranged to slide loosely upon the lower portion of the casing and to rotate thereon. The lower end of the sleeve G is fitted with abutton or cushion D', of rubber orother yielding material. The upper end portion of said rod has channeled thereon two beveled-wall helical grooves d d, which are arranged to be engaged each 5o with a stationary pin or projection f in the upper portion of the casing B. These projections will usually consist ot' two small screws having smooth hardened points.

Above the helical grooves the rod D has a short extension d to which is rigidly secured 5 5 a sleeve E, working loosely uponv the upper portion of the casing B, and which at its upper end carries a fan-head F. Said head is provided with a series of radial openings g to receive the shanks of the fan-blades, which are 6o held therein by set screws g. Ooiled around the rod wit-hin said sleeve is a helical spring H, which rests between that part h of the sleeve G to which the rod is secured and a shoulder h of the casing. y

The operation of the device is as follows: As the chair is rocked backwardly the button or cushion D comes in contact with the floor and forces the rod D upward. The pins or projections fbeing in engagement with the 7; helical grooves or channels d d said rod is caused to rotate as it moves upwardly, thereby rotating the sleeve E, the fan-head F, and the fans. As the chair comes forwardly, the spring H throws the rod downwardly, causing the fans an opposite rotation. In this manner a nearly constant rotation of the fans is maintained, this depending, of course, upon the movementof the chair. The device can be removed quickly from a chair when 8o not needed or itcan be allowed to remain with the fan-blades removed. This can be readily done by loosening the set-screws g.

Having described my invention, what I claim, and desire to secure by Letters Patent', 8 5 1s- The fantattachment for rocking chairs, consisting ot an elongated tubular casing designed to be supported in substantially vertical relation to a chair, an elongated rod D 9o which extends entirely through said casing, said rod having channeled therein two beveledwall helical grooves d, d, and having above said grooves a short extension d', a sleeve E rigidly secured to said extension and working loosely upon the upper portion of a casing B, a fan head F carried by said sleeve and having detachable blades, the pins f held in the casing B and engaging respectively the grooves d, d, the sleeve G in which the lower rco In testimony whereof I afx my signature in pxesenee of two Witnesses.

JOSEPH S. URBAN.
