IMPROVEMENT IN AUTOMATIC FLY-FANS.
Specification forming part of Letters Patent No. 162,944, dated May 4, 1875; application filed January 8, 1874.
I To all whom it may concern ratus. Fig. 2 is a View of the same in crossscction, on the plane indicated by the dotted line 00 00, looking in the direction indicated by the arrow :17. 1
The invention is a device to be suspended from the ceiling of a room by a cord, or supported on a pedestal or bracket, or in any other convenient manner, for driving and keeping away flies, mosquitoes, or other insects from the face of a babe, a sick person, a sleeping person, or a well person or persons who desire it. It consists of a clock-Work contained in a neat and substantial case, giving contrarily-rotating motion to two shafts, one projecting from either side of the case, on each of which slides a socket bearing arms, to which are attached fans or small banners or floats of light fabric.
The letter a denotes the containing'case, made, by preference, of sheet metal, with one side to take off like a cover, appropriately ornamented and painted. I show it in the drawing as suspended by a cord. The letter a denotes the key-hole, whereby, or whereat, the lnechanism is wound up and set in motion. The clock-Work, which I will denote collectively by the letter b, is contained in the case a, and gives rotary motion to the shaft 0, which, by gears c (1, gives rotary motion in the opposite direction to the shaft d. ()n the shaft 0 slides the socket e, which can be adjusted toward or from the case. From this socket extend the arms 6, which can be provided with sockets for holding fans 5 but we prefer to turn them at an angle, as shown, and pivot thereon by means of the swivel-rings g the floats or banners g. As these fans or banners revolve, they produce a gentle and cooling agitation of the air, and the r action will drive and keep away flies or other insects from their immediate vicinage.
For babes or other persons lying in bed, the case may appropriately be suspended by a cord from the ceiling of the room. For a person reading in a chair, it may be suspended by a cord or mounted on a pedestal or bracket.
The gears c d differ in size, so as to cause one of the shafts c d to rotate faster than the other, the effect of which is to cause the whole device to rotate horizontally when suspended by a cord. .This action can be assisted and increased by adjusting one of the sockets e f farther from the case a than the other. The letter fdenotes the sliding socket upon the shaft 01, and f f the arms corresponding to arms 6.
By means of this adjustability of the sockets e f upon the shafts c d, the action of the fans or floats can be made to affect more or less space, as desired.
We claim as our invention- 1. The combination-of case a, clock-work b, and the oontrarily-rotating fan-shafts c d.
2. The combination of case 0t, clock-work b, and the contrarily-rotating fan-shafts c d, arranged to have difierent speeds of rotation.
3. The combination of the two contrarily rotating fan-shafts c d with the adjustable fanbearing sockets e f.
4:. The combination of the contrarily-rotating fan-shafts c d, adjustable sockets e f, arms 6' f, swivels g, and banners g.
In witness whereof we hereto set our hands.
