FAN ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 451,188, dated April 28, 1891.

Application filed August 12, 1890. Serial No. 361,79 (No model.)

' to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The herein-described invention relates to improvements in fan attachments adapted to be operated by the movement of rockingchairs, cradles, and other like articles of furniture, and which is designed to provide an effective and simply-constructed device which is readily operated and the fan-propelling mechanism of which works without the slightest degree of noise.

In the accompanying two sheets of drawings, in which similar letters of reference are employed to indicate corresponding parts in each of the several views, Figure 1 represents a side View of one form of chair provided with my improved fan attachment, certain parts of which are illustrated in section. Fig. 2 is a horizontal section taken on line x in Fig. 1. Fig. 3 is a side elevation of a casing containing the gear-operatingmechanism connected with the fan-propelling shaft. Fig. 4: is a top view of the same. Fig. 5 is a vertical section taken on line a: in Fig. at, and Fig. 6 is an end view of the casing shown in Fig. Fig.7 is an enlarged vertical section of the shaft-propelling mechanism adapted to be operated by racks shown in Fig. 5; and Figs. 8 and 9 are horizontal sections taken through lines y and 2, respectively, in said Fig. 7. Fig. 10 is a plan view of a slotted disk employed in connection with the clutch mechanism shown in Figs. '7, 8, and 9.

In the drawings, A indicates the base of the chair, upon which the same rocks by m cans of the rockers A.

To the cross-pieces a and a is attached in any convenient manner an upwardly-projecting arm 13, which is provided at its end with a socketed sleeve Z), and upon which is secured in any well-known manner a casing 0, containing the shaft-revolving mechanism. Said casing is hollow, forming a chamber 0, and is provided upon its upper and lower sides with the threaded portions 0 and c, the lower one of which is arranged within the socketed sleeve 12, while to the upper one is secured a tube 6. The body portion of said casing 0 extends on opposite sides of said portions 0 and 0, being provided on its ends with diagonally-arranged holes and 0 which extend entirely through the casing and form ways or guides in which reciprocate the racks (Z and d, connected with the back of the chair by means of links 61 and d Said racks are secured in any convenient manner to a bar or cross-piece d", and the links (1 and d are pivotall y secured thereto at its ends, passon said shaft, fitting loosely thereon, being in frictional contact with said pinions. On each side of said disks and securedv to said shaft E are socketed clutch-collars e and a, provided within their socketed portions with serrations or teeth a and c As shown more especially in Fig. '7, the pinion 6 is provided with upwardly-projecting pins a which project through a slot c in'the friction-disk (2 (see Fig. 8,) and upon said pins are pivotally secured pawls e and upon said disk are arranged two pins o against which said pawls slide, and are thereby forced in engagement with the teeth or serrations in the socketed portion of the clutch-collar e by the movement of the pinion e. The pincontact between the pinions, friction-disks, and clutch-collars, as will be evident from Figs. 5 and 7. hen the racks are pushed forward, rack d operates pinion e, causing the pawls thereon to slide against the pins e 011 the friction-disk e whereby said pawls are thrown into lock ed engagement with the teeth within the clutch-collar 6 which causes the shaft E to rotate in the direction of arrow 1 in Fig. 8. At the same time the pinion e rotates in the direction of arrow 2 in Fig. 9, withdrawing the pawls 6 out of locked engagement with the teeth in the socketed portion in the clutch-collar c. On the return of the racks (Z and d pinion e is in locked engagement with clutch-collar (2 the same turning in the direction of arrow 4:, Fig. 9, and the pinion e and friction-disk 6 having its pawls withdrawn from thelocked engagement with the teeth in the clutch-collare, rotates loosely upon the shaft E. IIence during the backward and forward movement of the racks the shaft E will at all times revolve in the same direction. Thus it will be seen that the motion of the one pinion carries the pawls thereon against the relatively stationary pins on the friction-disks, thereby throwing the pawls into engagement with the adjacent clutchcollar, while the pawls on the other pinion are out of engagement with the teeth in the other clutch-collar.

From Figs. 8 and 9 it will be more clearly seen that the clutch-collars are provided with. oppositely-formed teeth, and when the rack cl moves forward pinion e rotates the clutchcollar 6 in the direction of arrow 5, (shown in Fig. 5,) while the pinion e rotates loosely on the shaft E, and thereby does not operate the clutch-collar 6 During the return of the racks, rack 61 operates pinion e, which causes clutch-collar e to move in the direction of arrow 6, and the other pinion 6 moves loosely on the shaft, from which it will be evident that said shaft E revolves in but one direction. Thefriction-disks have been slotted, as shown, which causes the pawls to be nioved back and forth against the pins on said disks, and thrown into or out of engagement with the teeth on the socketcd portions of the clutch-collars, according to the directions in which the racks move, as will be seen from Figs. 8 and 9.

In Fig. 1 it will be seen that the tube I), which contains the shaft E, is provided with a cap or collar b containing a bearing b through which the end of shaft E projects and rotates. A slightly-curved tube f is secured within said collar and communicates by means of another collar f with a straight tube f which is provided with the collar f said collars having bearings in which is arranged the straight shaft E. A tube g, having elbows g and 9 is secured to the tube f and has arranged therein a straight shaft E Springs or flexible shafting f" and f connect the ends of the straight shafts, as shown. NVithin the elbow g is arranged the spiral or spring g to which is attached a fan h in such a manner that when in operation the fan rotates in one direction above the chair-seat. Of course itwill be evident thatthe collar f can be constructed so that the tube f can rotate upon said joint and the fan thereby turned to either side of the chair.

Having thus described my invention, what I claim is- 1. In a rocking-chair or other seat, the combination, with the back thereof, of a tube provided with a flexible shaft and a fan, a casing to which said tube is secured, mechanism within said casing and secured to said shaft, racks for operating the same, and links connecting said racks with "the back of the chair, all of said parts being arranged and operating to cause said fan to revolve in one direction during the rocking motion of the chair, for the purposes set forth.
