FLY-

FAN.

SPECIFICATION forming part of Letters Patent No. 404,890, dated June 11, 1889.

Application filed August 4, 1887. Serial No. 246,166. (No model.)

To all whom, it may concern:

Be it known that I, HENRY S. BREWINGTON, a citizen of the United States, residing at Baltimore, in the State of Maryland, haveinvented new and useful Improvements in Fly-Fans, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in automatic fans, which will be hereinafter more fully described, and pointed out in the claim.

In the accompanyingdrawings, formingpart of thisspecification, Figure l is an elevation of the fan. Fig. 2 is a side view of the frame of one of the fans; Fig. 3, details, enlarged, of the gearing by which the fan-frames are rotated. j

A represents the stand, on which is secured in any suitable manner the figure B of an elepliant or any other animal. In the interior is located the proper machinery, operated by a coiled spring, as is usual in most of the automatic fans. A part of the shell of the animal is broken away at the origin of the tail to show the winding-wheel b of the coiled spring. The tail C Iis a lever for winding the spring, and is pivoted at c. It has on its 1nner end a pawl c', which iskept in place by a small flat spring c. Connected with this pawl and ratchet is a device (not shown in the drawings) by which, after the spring is wound up, the pawl will be detached, as in a clock or watch, to permit the spring to operate.

This lever, pawl, and winding-wheel are well-v known devices used for winding springs operating various machines. The train of wheels communicating motion to the main vertical sha-ft G are not shown, th ey being well-known devices.

A represents a basket in which tooth-picks or other articles can be placed.

On the elephants back are two chairs b b. Seated in each chair is a figure representing a monkey having the tail bent over to meet above their heads and form braces to support the tube F. The figures have their arms e e jointed to the shoulders at e. The hands clasp the crank g of the main shaft G, which is operated by the spring and train of wheels within the body of the elephant heretofore referred to. Thelegs of the figures are jointed to the body and are securely fastened to the chairs, and the chairs are also secured to the saddle B, so that there can be no motion eX- .cept in the arms and bodies, which are vibrated to and fro by the rotation of the crank g. .The tube F has a slit f on one side, having on one edge small notches f. F is another tube F', on which is a pin f, the purpose of which pin f is to rest in any fans at any elevation required. The tube F at its top has a flat and wide plate F, acting as a crown-wheel, having on its surface either a sheetof india-rubber or any other frictional substance. The main shaft passes through the inner tube F and projects above the plate F, as seen in Fig. l. On this projection are two sleeves H H.

I I are fan-shafts, having their inner ends z' t' journaled in sockets h, attached to the sleeve II by means of ears h', as seen in detail, enlarged, Fig. 3. This connection permits a free rotation of the shaft within the socket h, and is held therein by means of a screw h in the socket, and the end of which enters a neck t" in the end of the shaft I. A ball-and-socket joint can be substituted for this device. A sleeve H is secured on shaft G above H', and has ears on opposite sides, to which are jointed the two rods .I J, the other ends of which rods are jointed to ears j on sleeves J J on shafts I l, through which the shafts are allowed to turn freely.

Attached to shafts I I are thin bright metal strips I I, which are secured at their ends to braces L; k and the small friction-wheels L L, so that these strips I I have the form of long oval fans, as seen in Fig. 1. These strips are much wider at the en'd of the shafts-I I, as seen in Fig. 2, which shafts are secured in holes in the middle of the strips in any suitable manner. These strips alone form`the fans, and are not covered with fabric, as other fans are 5 but, being of bright metal, when they move around in the orbit and are rotated on the shafts I I by means of the small friction-wheels L L, as they are carried around over the crown-wheel F the flashing of the light will drive away flies and other insects. In the sleeve His a set-screw 7L, by which the one of the notches f and thereby sustain thel Vithin tube y IOO shaft is prevented from turning in the sleeve and also by which the sleeve H is secured at any place on the shaft.

Fig. l represents in black lines the shafts I I in a straight horizontal line. rlhe dotted lines represent the fans slightly elevated and at an angle to each. other. sliding sleeve II down on the shaft G and securing,` it by the set screw. This does not change the relative position of the plate Fl and the friction-wheels L L, the rims of which wheels are made slightly convex in cross-section, so that at whatever angle they may be placed in, the surfaces will be in contact with plate F, so as to produce rotary motion as they travel in the orbit.

The operation of this fan is as follows: By moving' the tail of the elephant up and down as a lever the spring' will be wound up. By loosening' a catch in the train (not necessary to be shown) the train will be set in motion, the shaft G will be turned, and the 'figures in the chairs, by being moved, will appear to be revolving the shaft by means of the crank r which they hold in their hands. The plate F being' stationary, t-he shaft G, when revolved, will carry around with it the fanshafts II and with them the wheels L L,which will cause them to rotate by friet ion with This is done by plate F and turn the rims of the fans around with their shafts I I.

The fans can be arranged at any height by means of the pin f and notches f heretofore described. At the base of the tube Fis a thumb-screw Z, which is to secure the shaft G and prevent it from turning, and when the machine is to be set in motion the screw is to be loosened.

Even date with this application I have tiled an application for a patent for a design covering' sueh features in said invention as are applicable thereto.

I claim- The combination of the revolving' shaft G, the tubes F and F', the latter of which is adjustably supported Within the former by the pin f and notches ff, the., and has on its upper end a frietion-plate F the frictioil- Wheels L L, shafts I I, sliding sleeves 1I II', and connecting-rods .I J and'sockets h 7L, substantially as described.

In testimony that I claim the foregoing'4 as my own I hereto a'fiix my signature in presence of two witnesses.

HENRY S. BREIVINGTON.
