UNITED STATES PATENT OFFICE.

WALTER E. COLEMAN, OF NEW DORP, NEW' YORK.

FAN.

SPECIFICATION forming part of Letters Patent N0. 697,448, dated April 15, 1902.

Application filed July 12, 1901.

To all whmn it may concern:

Be it known that I, WALTER E. COLEMAN, a citizen of the United States, residing at New- ,Dorp, Richmond county, and State of New appertains to make and use the same.

My invention relates to fans for cooling and ventilating apartments; and it consists in the special construction and arrangement of parts hereinafter described and claimed spocifically.

In the accompanying drawings, Figure 1 represents a side elevation of an electric fan provided with my improvements; Fig. 2, a top view of the same with a portion of the fan-guard broken away; Fig. 3, a front View; Fig. 4, a rear View. Figs. 5 and 6 are respectively a top view and a side elevation of a modified structure. 7

M represents, symbolically, an electyic motor, of any ordinary construction, for actuating the fan F.

G is the guard-frame surrounding the fan. Pivotally supported in this guard-frame G are a series of deflectors D, free to rotate in whole or in part upon their longitudinal axes. Thus in the first four figures they are connected by a rodd, which limits the degree of their rotation, whereas in the remaining figures they are provided with pulleys d and connected thereby with belts (1 so that the slats or deflectors are capable of makingcontinuous and complete revolution upon their longitudinal axes. In this latter arrangement the axis of oneof the deflectors is provided with a pulley P for the reception of a belt B, which passes over idlers i '6 and around the power-pulley P P on the motor-shaft m,

crank-pin s, which in turn actuates the rocklever'R, the forward bifurcated end of which engages with a crank-pin n on one of the deflectors D. As a result the rotation of the crank-pin 8 causes the deflectors D to vibrate back and forth, and thereby deflect the aircurrent from left to right and right to left alternately and wish, thus differing from the result attainedin themodifications shown in Figs. 5 and 6, in which the continuous rotation of the deflectors D changes the current of air from right to left or leftcto right, as the case may be, suddenly, the sweep of the air-current being in one direction only.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with an electric motor M, and fan F, of the guard G, the series of slats D, pivotally supported in said guard G, and means for automatically moving said doflectors or slats D, by the direct action of the motor, substantially as herein set forth.

2. The combination of the electric motor M, the'fan F, the guard G, a series of pivoted I slats D, and mechanism for transmitting motion from the motor-shaft m, to said deflectors D, for the purpose and substantially in the manner described.
