ROTARY IAN.
Specification of Letters Patent. lApplication filed March 14, 191.1. Serial No. 614,416.
Patented Dee. 12; 191er.-
To vall lwhom 'it-may comem: U Be it known that I, JAMES INGLIs, a citizen of the United States, residing at Detrolt,
in the county of Wayne and State of lMichigan, have invented certain new and useful Improvements in Rotary Fans, of which the following is a specification.
The invent-ion relates to rotary fans, and especiallyto such as are used for ventilating purposes.
The object of the invention is toprovide.
an improved means of this character ad-` justable to direct the current of air produced by it at different angles',or`e`ven tov reverse the direction of the current of air.
A further object is to provide such a device adapted for use in the walls of buildings, or with a window-board placed in the window frame above or below the window sash. 1 l An embodiment of the invention is illustrated in the accompanying drawing, where- 1n- Figure 1 is a rear elevation of the fan with parts broken away; Fig. 2 is a transverse section, vwith parts in elevation, and Fig. 3 is a side elevation showing the fan tilted; j
In said drawing A indicates a fan-wheel of suitable form, and BY any suitable motor for driving the fanwheel. Preferably an' electric motor is employed, as shown, on the shaft @of which the fan-wheel is mounted. In order to provide for the adjustment of the fan-wheel to. direct the current of air produced thereby in diferent'directions, it is mounted in a frame C journaled upon any suitable support D, and preferably provided with suitable means E, for moving it to its A adjusted positions. 'As shown, one of the journals 'c of the frame has attached there-v to a gear e meshing with a worm f upon a rod or shaft g journaled in a bracket t profan and support whereby neitherl .the fanl wheel nor the motor projects an undue dis- :clear from Fig. 3.
the support D y-through lwhich the .air is in the preferred construction the pivotal tance Y, beyond the support D. To this end i the .distance -from its'point of intersection i with-,the fan shaft to the rear ofthe motor is substantially the same as the distance from such point to the-periphery of the fan wheel. By this means the tips ofthe fan blades` and the rearof thermotor describe substantially the same circle when the device is swung around its ivotal axis, as will'be he circular opening j driven or drawn by the fan` wheel may -hence be-of a diameter which is notvmaterially larger than the diameter of' the fan wheel, and yet permit the fan to be tilted as illustrated in Fig. 3 so that it "occupies a position partly on one side and partly on the other side of the opening. Or With a minimum size of opening the fan may be entirely y f reversed if desired. This `construction not only provides the minimum degree lof projection on each sideiof the vopening but also reduces the size andweight of the support D. The support is preferably provided withannular flanges k c which when the fan wheel is running ona horizontal axis provide a housing for the fan wheel. The pivotal axis of the frame C is preferably located at a point between the fan wheel and the motor in order to best secure these results. It is desirable, however, tok support the device from the *motor casing, and for' this purpose the frame vC is preferably bowed rearwardly, and is connected with the motor casing at or near the middle of the y latter. y The frame for the fan-wheel may be mounted at any angle onits support, and the gears and rod/provide a convenient means for adjusting the fan-wheel and frame, especially when the fan is located'out of reach. These means are also especially advantageous when the support for the frame and fan-wheel is in the formof a wall plate and located in the wall or window of a building.-
By manipulating the hand-wheel the fanwheel lmay' be adjusted to direct the current of air blown from it at different angles,`and
by turning it far enough Vthe fan may be reversed so asto direct the current of air in` the opposite direction. Forr instance, if the fan be located wallaor windowof a building, itfinay vbegman'plpllated to blow llaa..
