UNITED STATES PATENT oEEioE. N

L. REBSTOGK AND N. REIMEL, OF PHILADELPHIA, PENNSYLVANIA.

AUTOMATIC FAN.

Specification of Letters Patent No. 17,517, dated June 9, 1857.

To all who/m, 'it may concern:

Be it known that we, LAWRENCE BEB- s'rook and NICHOLAS REIM'EL, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Ventilating-Fan; and we do hereby declare that the following is a. full,

clear, and exact description of the same,

will proceed to describe it.

A represents the base of the implement, which may be constructed of wood or other material, and of circular form. This base is placed upon casters (a) of the usual construction. On the upper surface of the base, near its edge, an annular groove, B, is made, and C is a circular platform supported by two pedestals, (b) (b), and two hollow uprights, D, D, the uprights passing through the platform and extending upward a suitable distance. The lower ends of the pedestals, (Z2) and uprights, D, D, are provided with rollers or casters (c) the peripheries of which are fitted in the groove, B. The under side of the platform, C, has a pendent rod, E, attached to it; the lower end of said rod being placed or fitted in a step (el) at the center of the base, A. The platform, therefore, with its pedestals and uprights, may be rotated or turned upon the base, A, the above parts being secured upon the base by the pendent rod, E, and the rollers or casters (c) which fit or work in the groove, B.

F, F, represent two uprights, attached to the platform, C, and G is a fan, the shaft (e) of which works in bearings in the upper ends of the uprights, F, F. The shaft (e) has three or more radial rings (f) attached to it; and a pinion (g) is Placed on each end of the fan shaft (e). H, H, are two toothed wheels, the aXes (7L) (h) of which pass transversely through the upper ends of the uprights, D, D, one through each, and a drum (i) is placed on each axis (it), the drums being within the uprights, and having cords and weights (le) attached to them; see dotted lines in Fig. l.

The wheels, H, H, gear into the pinions (g) (g) on the fan shaft (e), and the wheels H, H, are placed loosely on their aXes, and connected with them, when they are turned in one direction and rotate the fan G, by pawls (l) and ratchets (071,); the axes being disconnected from the wheels when turned in the opposite direction; so that the cords (j) may be wound upon the drums without operating the fan and wheels. The ends of the axes (7L) are made square to receive a key for winding up the weights.

The wheel, H', gears into a pinion (n) on a shaft (o) the ends of which are fitted in pendents, (p), at the ends of a bar (g) attached to the upper end of one of the uprights, F. The outer vend of the shaft (o) has a scape wheel (r) upon it, and (s) is a pallet which works into the scape wheel (10,' the pallet being connected with a pendulum (slby a crutch (t) these parts being arranged precisely similar to those in an ordinary clock.

When the cords (j) are wound upon the drums (i) the fan G will be rotated by the.

gearing or clock movement described, and a blast ofair will of course be produced by the rotation of the fan. By turning the platform, C, on the base, A, the fan G may be placed in any relative position with the person receiving the blast, so that. the person may receive the blast more or less direct, and consequently of a greater or less strength, as desired.

The above implement being on casters may be readily moved from place to place. It may be placed at the bed-side, and kept in operation during the night, or it may be placed near a reading or dining table, or by an escritoire, to fan the persons sitting at such articles of furniture. The device is very compact, and when not used as a ventilator, the platform, C, may serve as a sewing or work table, and may, if desired, be provided with drawers.

I do not claim, broadly, the driving of revolving fans by clockwork, as such contrivances have long been known and used. Neither do I clailn, broadly, the revolving of mechanism around a given axis, by placing the mechanism upon movable frames.

The rotating domes of Observatories, telescope stands, and other species of mechanism are examples of this kind. But to the best of my knowledge and belief, there never has been made a fan driven by clockwork and arranged as herein shown, so as to be capable of being readily turned upon an axis Without moving the whole apparatus. The current of air is thus readily directed toward any given point in an apartment. My invention therefore constitutes a new and useful article of manufacture. No apparatus like it has ever before been known or used. Therefore,

I claim and desire to secure by Letters l0 Patent, as a new article of manufacture- A Ventilating fan, constructed as herein Witnesses:

HUGH CLARK, CONRAD H. YEARLY.
