CANOPY ROCKING FAN.

To all whom it may concern: V

, Be it known that I, EM L F. H RRMANN, a citizen of the United States, residing at can Baxter avenue, Louisville, in the county of Je-fferson and State of Kentucky, have invented anew and useful Canopy Rocking Fan, of which the following is a specificati-on.

This invention relates to fan attachments for chairs or the like and has for its principal object to provide a fan which is actuated by the rocking movement of the chair.

Another important characteristic of this invention resides in the provision of a fan, an oscillating blade and a set of rotary blades, the oscillating blade imparting mo tion to the rotary blades.

Another object of this invention is to provide a device of this character which is simple, durable and efficient in its construction and which may be manufactured at a nominal cost.

With these objects in View, others will appear as the following description is taken in connection with the accompanying drawings; in which Figure 1 is a front elevation of my device showing the same attached to the-back of a chair. Fig. 2 is a side elevation showing the chair in section. Fig. 3 is a modified form of my invention showing a weight in the place of the oscillating fan blade.

Referring to the drawings in detail 1 designates a top rail of the back of a rocking chair of any common construction on which is secured a bracket 2. This bracket 2 is preferably formed of wood and is substantially L-shaped as shown in Fig. 2. One extremity of the bracket is bifurcated to provide the divergent legs 3, the lower eX- tremities of the legs being formed with substantially U-shaped feet as at 4, the feet engaging the rail 1 and held in rigid position thereupon by means of the set screws 5. Owing to the peculiar shape of the bracket it will beseen that when the same is in applied position upon the chair the free extremity thereof will be disposed directly above the seat of the chair.

Vertically arranged upon the free extremity of the bracket and intersecting the same at right anglesis a U-shaped yoke 6. One of the arms of the yoke 6 is extended through the bracket at a point remote from the free end thereof as at 7, while the re- Application filed June 1, 1914. Seria11\To. 842,333.

Specification of Letters Patent. Patented Oct, 17, 1%16,

maining arm is secured to the free end of the bracket as at 8; Thus it will be seen that the semicircular portion of the yoke is disposed upon the upper side of the bracket while the extremities of the arms vare disposed upon the under side. To form a rigid support for the yoke and to keep the same in proper position upon'the bracket, Ihave provided the latter with a bearing plate 9,:

the same being of U-shaped formation. and having'the free ends thereof secured to the upper sides of the bracket, while the upper end thereof engages the medial portion of the yoke 6. The opposite sides of the bearing plate 9 are provided with alined bearings in which is journaled a shaft 10, the shaft being arranged at right angles to the bracket and having its opposite extremities provided with fan blades 7 11 which are of any suitable construction. Pivotally mounted upon the bracket and between the parallel arms of the yoke 6 is the upper extremity of a fan blade 12, the same depending from the bracket and adapted to oscillate when rocking movement is imparted to the chair. Wound about the shaft 10 is a cord 13 the extremities of which are trained around pulleys l4 journaled in the ends of the yoke 6, and have their extremities secured to the opposite sides of the fan blade 12.

It will be seen from this construction that when oscillatory motion is imparted to the blade 12 the cord 13 will be moved over the pulleys 14 whereby rotary motion will be imparted to the shaft 10 to cause the fan blades 11 to rotate first in one direction and then the other, the direction of rotation depending upon which way the blade 12 is moved.

In practice the bracket is secured to the back of the chair as shown in Figs. 1 and 2 so as to cause the free end of the bracket to be disposed directly above the seat of the chair; WVhen the occupant imparts rocking motion to the chaiiythe blade 12 being free to swing, the inertia of the blade will cause the same to oscillate or swing upon its pivot, thereby causing a fanning of the air in close proximity to the occupant. Upon movement of the blade 12 rotary motion is imparted to the blades 11, first in one direction and then in the other, through the medium of the cord 13 as has been described. Thus it will be seen that further fanning of the air is accomplished in addition to the moving of the blade 12. It has been found in practice that the rotary blades serve to keep flies and other troublesome insects out of the zone of the occupant, while the oscillating blade 12 agitates the air sufiiciently to keep the operator cool.

In Fig. 3 I have shown a modified form of my invention, in which I have substituted a weight 15 of any suitable construction, in place of the blade -12. Owing to the fact that the weight 15 has less air resistance than the blade 12, a greater speed is imparted to the rotary blades, as will be under stood. The Weight 15 is substituted for the blade 12 when it is desired to use only the rotary blades for agitating the air.

Although I have shown and described a specific form of fan, I wish it to be understood that various changes in the size, shape, proportion and minor details of construction maybe made without departing from Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

the spirit and scope of the appended claim.

What I claim is A fan attachment for chairs comprising a bracket a U-shaped yoke secured to one yoke, a member pivotally mounted upon 1 said bracket between said pulleys and depending from said bracket, a shaft journaled in said bearing plate and having the opposite extremities thereof provided with blades, and a cord Wound about said shaft and passing over said pulleys and having the opposite extremities secured to the opposite sides of said member.
