INVENTDFIL PATENT XVILLIAM FAY, OF NEW ORLEANS, LOUISIANA.

IMPROVEMENT IN AUTOMATIC FANS.

Specification forming part of Letters Patent No. 137,189, dated March 25, 1873.

To all whoni it may concern:

Be it known that I, WILLIAM FAY, of the city of New Orleans, parish of Orleans and State of Louisiana, have invented a new, useful, and Improved Automatic Fan, and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing constituting a part of this specification.

My improvement relates to a mechanical combination and arrangement oftoothed-wheel gearing operated by spring-power, through the agency of which rotary motion is imparted to a flywheel, from which, by means of cranks and connecting-rod, reciprocating motion is transmitted to a rock-shaft, in which may be inserted, at any desired angle, one or more fans of the kind in general use for fanning or cooling purposes.

An especial object accomplished by my invention is that it may be rendered equally effectual for the purposes for which it is designed, in almost any relative position in which the same may be placed, by simply arranging or adjusting the fan upon the rockshaft, before mentioned, so that its effects may be directed to the face of the person upon whom the same are desired to operate; but my invention and its mode of operation will be more clearly understood by reference to the drawing, whereon at Figure l is shown a front elevation, having a portion of the outer casing thereof broken away the more effectually to expose to view the mechanical arrangement of its several internal parts 5 and at Fig. 2 is a side elevation, with the said outer casing also partially broken away with the like object as expressed for Fig. 1.

My apparatus, as at present constructed, is operated by the two volute springs A and B, the inner ends of which are secured to the respective shafts a and b, having bearings in the frame 0, while the outer extremities of the said springs are attached to the connecting-bars of the said frame 0. Upon the said shafts a and b are rigidly secured the respective ratchetwheels c and d, which, when the said springs are wound up, engage the respective spur-wheels d and e, by means of the pawls f and g and springs 71. and i therewith connected.

In the process of winding up the said springs the said spur-wheels d and 6 remain loosely upon their respective shafts, and for the purposes of winding up the said springs the said shafts a and b are prolonged sufficiently beyond the said frame 0, so that a key may be applied thereto, as plainly shown.

The spur-wheels d and e aforesaid engage the respective pinions 7c and I placed upon the respective shafts m and 02. Upon the said shafts m and n are likewise placed the enlarged cog-wheels 0 and p, gearing into the pinions r ands upon their respective shafts t and 20. Upon the said shafts t and a are placed, respectively, the cogwheels v and 20, both of which engage the pinion a: upon the fly-wheel shaft D.

The combined power of the two springs A and B is transmitted to the said shaft D so as to move the same, and consequently the flywheel E thereon placed, continuously in one direction. Upon the side of the said fly-wheel E, and at any required or suitable distance from its central axle, I place the crank-pin H to receive one end of the connecting rod shown. This connecting rod has its opposite end connected with one end of the cranklever L, which in turn has its opposite end inserted in or through the rock-shaft M, having bearings in the projecting frame N. By the revolutions of .the fiy-wheel E an oscillating or vibratory motion is imparted to the said rock-shaft M through and by means of the connecting-rod and cranklever L aforesaid. In the said rock-shaft M, through perforations m m therein made, may be inserted at any required angle the stem or handle of the fan M tobe employed by my apparatus. 0 is a balance-weight, the stem of which is likewise inserted within the said rock-shaft M for the purposes of giving regularity of movement to my device. The balance-weight 0 should always be placed in the same plane with that of the fan employed. This is an essential requirement.

The whole apparatus, above described, is secured to the upright standard P of the stand R by means of the loose links Q and Q, and

may be raised or lowered thereupon, or re volved thereabout, and secured in any desired posit-ion thereon by means of pins, as clearly shown.

FFICE.

It is clearly obvious that one spring instead of two might be employed for the operation of my device, and to this end I reserve the privilege of employing one or more. 7

The machinery for the operation of the fly- Wheel is inoased in a neat box, and the whole device is cheap, simple, economical, of easy construction, and effectual for the purposes for which it is designed; and having described it What I claim as new, and desire to secure by Letters Patent, is

The operatingmechanism herein described, which is substantially that of the clock, in

combination with a rock-shaft having a series of perforations, m on, fan M, and balanceweight 0, the whole being constructed and arranged to permit of the fan and weight being adjusted on the rock-shaft, as described, and for the purpose specified.
