Tiltable and adjustably oscillatable portable electric heater/fan

A portable heater/fan which can be made to oscillate from side to side over either one of two different angular distances or remain stationary and which can be tilted backward or forward so as to provide a beam of hot or cold air whose lateral extent and direction can be adjusted over two mutually perpendicular axes, said heater/fan comprising:

• a. a base adapted to be placed on a horizontal surface for supporting the heater/fan.
• b. a shaft mounted on said base for rotation about a vertical axis,
• c. a main gear fixedly mounted on said shaft for rotation therewith,
• d. a synchronous electric motor mounted on said base and operatively connected to said main gear for causing said main gear to rotate with said shaft about said vertical axis,
• e. first cooperable limit means on said base and said main gear for causing said synchronous motor to oscillate said main gear through a first angular distance about said vertical axis.
• f. second cooperable limit means on said base and said main gear for causing said synchronous motor to oscillate said main gear through a second angular distance about said vertical axis smaller than said first angular distance.
• g. switch means for selectively actuating said synchronous motor and for selectively rendering either said first limit means or said second limit means operative to select the angular distance of oscillation of said main gear about said vertical axis.
• h. a neck joint fixedly mounted on said main gear for oscillating therewith.
• i. a compartment having a heater/fan for selectively providing a beam of hot or cold air through the forward end thereof, and
• j. means for pivotally mounting said compartment on said neck joint for selective tilting movement in either a forward or rearward direction relative to said base.
• k. said first cooperable limit means comprising:
• i. a first stop on the periphery of said main gear,
• ii. a second stop on the periphery of said main gear at a first arcuate distance from said first stop, and
• iii. a first fixed bar on said base positioned between said first stop and said second stop so as to hit said first stop when said main gear rotates a predetermined distance in one direction and so as to hit said second stop when said main gear rotates a predetermined distance in the other direction,
• l. said second cooperable limit means comprising:
• i. said second stop on the periphery of said main gear
• ii. a third stop on the periphery of said main gear on the side opposite said first stop and at a second arcuate distance from said second stop, said second arcuate distance being less than said first arcuate distance, and
• iii. a second bar on said base selectively movable by said switch means into position between said second stop and said third stop so as to hit said second stop when said main gear rotates a predetermined distance in one direction and to hit said third stop when main gear rotates a predetermined amount in the other direction to limit the angular distance of oscillation to said smaller second angular distance, and movable by said switch means out of position between said second and third stops so that the angular distance of oscillation is determined by the engagement of said first and second stops with said first bar to limit the angular distance of oscillation to said larger first angular distance.

An electric fan comprising:

• a. base adapted to be placed on a horizontal surface for supporting an electric fan,
• b. support means mounted on said base for rotation about a vertical axis,
• c. a synchronous motor mounted on said base and operatively connected to said support means for causing said support means to rotate about said vertical axis,
• d. first cooperable limit means on said base and said support means for causing said synchronous motor to oscillate said support means through a first angular distance about said vertical axis, said spaced first cooperable limit means comprising first and second fixed stops on said support means and a first bar fixedly mounted on said base,
• e. second cooperable limit means on said base and said support means for causing said synchronous motor to oscillate said support means through a second angular distance about said vertical axis smaller than said first angular distance, said second cooperable limit means comprising said second fixed stop and a third fixed stop on said support means spaced therefrom a distance less than the distance between said first and second stops and a second bar movably mounted on said base and selectively movable into and out of position between said second and third stops,
• f. switch means of selectively actuating said synchronous motor and for selectively rendering either said first limit means or said second limit means operative to select the angular distance of oscillation of said support means about said vertical axis by moving said second bar into said position to render said second limit means operative and by moving said second bar out of said position to render said first limit means operative, and
• g. a compartment having an electric fan assembly mounted on said support means.
