FAN.

SPECIFICATION forming part of Letters Patent No. 330,627, dated November 17, 1835.

Application filed J une 20, 1884. Serial No. 135,525. (No model.)

To all whom it may concern.-

Be itknown that I, JAMES M. SEYMOUR, a citizen of the United States, residing in Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Fan Attachments, fully described and represented in the following specification and the accompanying drawings,forming a part of the same.

This invention consists in a self-acting gravity or friction driver, by which the fan is gently rotated when unclutched from the driving-shaft, and in means for clutching the fan positively to the shaft when abreeze is desired. The fan is thus adapted to perform two entirely different functions: first, to drive away flies and insects by moving at so slow a rate as not to agitate the air; and, secondly,to ventilate the apartment in a greater or less degree when clutched to the driving-shaft.

These improvements are also applicable to columnar fans, as shown in another application filed herewith, and in which I have claimed specifically one modification thereof.

In the drawings, Figure 1 is a side view of a suspended fan provided with my improvement, the friction-disk and driving-pulley being shown in section on the line 00 min Fig. 2; and Fig. 2 is a sectional plan on the line 3/ y in Fig. 1.

A is the ceiling from which the fan is suspended by a vertical shaft, 0, mounted in bearings 0 upon a hanger, B. D is the driving-pulley. E E are the fan-blades; F,the hub by which the latter are attached to the shaft; and G is an oil-cup suspended below the hub to catch the drip from the shaft 0. The pulley D, which is driven by the belt 0, is shown placed on the shaft in contact with the lower bearing of the hanger, and runs loosely upon the shaft with a friction driving-disk, D, to which it is attached. A friction clutch-plate, D is fitted upon the shaft above the drivingdisk D, upon a spline, a, in such a manner that the plate may be moved to and from the disk D. A shifting-lever, I, is applied to the hub b of the plate D to increase or diminish the friction at the point of contact. The

lever I is pivoted to the hanger at z', and its rear end is connected with a cord, J, which is carried over pulleys e e to a point beyond the sweep of the fan. It may thus hang down withwithin convenient reach of the operator. The

end of the cord is provided with a ring, d, and

one or more hooks, d, are affixed to a wall or some fixture in the apartment, so that the ring may be hooked thereon and the lever held in its operative position. When'the cord hangs loose, the plate D rests upon the revolving disk D merely by its weight, and derives therefrom merely enough motion to turn the fanblades gently around and agitate the air sufficiently to drive flies and insects from the apartment without making any perceptable wind. The friction faces may evidently be pressed together with any desired degree of force, and the speed transmitted to the fan thus be raised up to the full velocity of the driving-disk D, the hooks d serving to secure the cord J and the lever I in whatever position may be required to produce the desired effect. The lever I- may be extended in the opposite direction from its fulcrum and provided with a weight, W. In this case the fan may be stopped by lifting such weight and lever, as by the cord L,actuated by a ring, and secured to hooks g,like the cord J described above.

In lieu of the hooks d, other means may be employed to hold or clamp the cord when adjusted in the required position, as the means used are entirely immaterial, provided the cord be fixed within reach of the operator. The means of operating the clutch thus secure results not heretofore obtained with any other mechanism.

I am aware that friction-clutches have been used in a great variety of combinations, and that springs and weights have been used to throw the clutch into or out of gear, and I therefore disclaim any such construction; but I am not aware that any such combination has existed heretofore as I have described above, in which a fan is so actuated by a frictionclutch as to perform two distinct and different functions, and in which the separable parts of the friction clutch revolve continuously in contact with one another, and operating to perform one of its functions-namely, to frighten away insects when it is not required to perform the other function-that is, to produce a breeze.
