IMPROVEMENT rIN AUTOMATIC PAN.

The Schedule referred toin these Lettera Patent and making part of the same.

To allwhom it may concern Be it. known that I, `Geenen H. BRIGGs, of Mont.-

gomery, in the county of Montgmery and State of Alabama, have invented a new anduseful Improved AutomaticFam and I do hereby declare that the following is a full, clear, and exact description thereof, sucient to enable those skilled in the art to which ,my invention appertains tomake and use `the same, reference being had to the accompanyingdrawing making part of this specification,V4 in which- Figure 1 is a plan or top vew of the mechanism lfor operating the fan.

Figure 2 is a side view ot'` the same.

" 'Figure 3 shows the-,mechanism'incloscd'ina box or casinghfcrming a Stand or platform for 4the fan.

Figures 4 and 5 are detailed Vviews, hereinafter more particularly referred to.j

The nature ot' my invention consists in constructvingan automatic fanwithadjustable telescopic supports for one or more fans or brushes; also, in-imi l artiu a reci )rocatixwrotar motion to the ian-shaft- P. o o a also, `in lthe `peculiar,arrangement ot' an adjustable device for increasing or diminishing the speed of the fanshaft.

The fan-shaft is formed in two sections, A B, and

, provided with sockets a, or other suitable means for att-aching the fans.

-The upper sect-ion, B, is a telescopic rod, which may be `extended or contracted at pleasure. .It is attached to the lower section A by an ordinary hingejoint, and is held in a verticaliposition, or inclined at any desired angle by means of an adjustable brace.

The brace O consists of a bar hinged to utwo collars. one of which is fastened to the section A, and

the 'other slides 'eely on the section B, and is pro- `vided with a set-screw, by which it may be held at any desired point. z

9 Two-different positions of the sections and brace are shown respectively in gs. `4 and 5.x The fans D- are' attached i to thel lower section A,

` and to the upper section B are attached any desired "number oflpea-fowl' feathers or brushes, or tassels made of any suitable material, which will serve as av fly-brush and mosquto-chaser.

Fans, also-in any desired number, may be attached `to the upper section B, hinged to bars or rods radiating from the sec tion B, so as to have a-swinging inotion;

The section A is journaled in the frame-work which holds the operating mechanism.

Attached to it, justabore the upper journal, is a gear-wheel, E, which receives motion from another gear-wheel, F.

To the shaft of the gear-wheel F is rigidly attached one end of a slotted bar, G, in the slot of which works a screw-pin, H, project-ing from a disk vor plate, I, attached to a shaft, K, on which is a'pinion,yL, through which motion is imparted from the operatingmechanism, which may consist of an ordinary spring clockwork.

The disk or plate I has a series of holes placed at differentdistanees from the center, and, by inserting the screw-pin -H in the ldifferent holes, diiiercnt de' grecs of velocity are attained by the wheell F, as well as different length of oscillation of the slotted bar G,

The operatingr mechanism imparts a continuous ro tary niotion'to the disk or plateI, land the screw-pin H working in the slot, causes the bar G to oscillare and impart a reciprocating rotary motion to the wheel F, Iend through the wheel E to the fan-shaft, giving the fans a back-and-forward motion.

When the section B is turned down horizontally, as shown in figs. 1, 2, and 4, it oscillates back and forward, with the section A as its center.

This fan may be placed at one end of a table, and the section -Bexteuded so as to l'each to the other end, the mechanismbeing so adjusted as to not give too great a sweep to the shaft.

The stand or platform may be provided with a clamp or thumb-screw, or other suitable means for attaching it tothe head-board of a bcdstead, where its efficiency as a mosquito-chaser will be readily appreciated` What I claim as new, and desire to secure by Letters Patent, isf- 1 In an automatic fan, thecombination of the adjustable telescopic rod A B, which may be extended or contracted and adjusted at'dil'erent angles with the gearing E'F, slotted bar G, plate I, and'adjustable wrist-pin H, whereby a reciprocating rotary motion is imparted to the fans, when arranged and operating as ero. lar-. sarees'.
