SPECIFICATION fo in part of Letters Patent No. 723,994, dated March 31', 1903. I
' Application filed O ctober 15.1902. Serial No. 1 27,381 (Ne model.)
To calla/homz't may concern:
Be it known that I, CHARLES A. 11101:, a subject of the'King of Sweden and Norway, and a resident of Belleville, Essen county,'New Jersey, have invented certain new and useful Improvements in Fans, of which the following is a specification. i
My invention relates generally to fans, and has more particular referenceto means whereby a fan will be caused to oscillate or turn from one side to the other as it rotates.
The object of my invention is to produce a structure which is simple, inexpensive, and efficient and one which will not mar the appearance of the fan.
In carrying out this object myinvention consists in a vane for oscillating the fan, which is adapted to be moved alternately in the same plane into operating position on either side of, the center of. the fan, and-also in means for regulating the distance and the speed of the oscillation.
I shall describe a fan adapted to oscillate in the manner set forthembodying my invention and afterward, point out the novel features in the claims. a 1 In the drawings I haveiembodied my invention in'a suitable form; but changes in construction may of course bemade within the scope of. the claims.
In the said draw ngs, Figure l is a front, view of a fan embodying myinvention. Fig.1
2 is a side view of Fig. 1. Fig. 3 is a plan view of the base of the fan-motor. Fig. 4 shows a modification. f 7
A represents a fancomprising the vanes a, mounted on the armature-shaft a 'of the mo; tor a3. The motor a is of any suitable construction and is mounted loosely, so that it can turn from one side to the other on the upright stem 1) of the base B, which rests in the ball-bearings b and b The motor is prevented from becoming detached from the base by the screw b which projects into the cir cumferentialv groove b of the stem 1). The base B further carries the circulartrack b, which is provided with two arc-shaped slots t of any desired length and'wi'th stops b which are conveniently in the form of setscrews adapted to be adjusted in the said slots to regulate the distance of the oscillation.
The fan is, as is usual, inclosedin a wire guard O, which is attached to the motor by means of the arms 0'. At the lower side of this wire guard and in substantially the same vertical plane as the center of the fan is a horizontal sleeve 0 into which is inserted the arm (1 of theoscillating device or vane D.
"From the arm'd extends the arm d provided with a hook, as (1 inserted into the bushing d of the vane proper, d, and held thereby means of the screw 1. From the other end of the arm (1 extends the projection 01? to engage alternately with the stops of the base B.
If the vane d now be on the right-hand side of the center of the fan, as shown in Fig. 1, the force of the air coming from the fan as it rotates will turn the said fan until the projection 01 engages with one of the stops b which has the effect of stopping the turning motion and of causing the vane d to be moved oscillation, the vane 01 is inclined more or less or not at all, as shown in Fig. 2, the set- 'screwd permitting such adjustment. "The vane d? Will preferably be placed in .front of the fan, so as to receive the blast coming from the same. It may, however, as
d 9,"be placed. in the rear of the fan, as the current of air produced by the said fan would turn it whether the vane is placed in front or 'in rear of the fan.
' Obviously several vanes may be used, or the vane 01* may be composed of several blades or disks. The shapeof the Vane d is shown shown-in Fig. 4, Where the vane is marked .in the form of a disk; but it may of course 2. The combination with a fan, of means, Q
for oausingjt to oscillate as it rotates, comprising a vane in the path of the current of air produced by the fan, means for moving the said vane alternately into operating position, in the same plane, on either side of the center of the fan, and means for adjusting the vane thereby regulating the speed of the oscillation.
The combination with a fan, of means, for causing it to oscillate as it rotates, comprising a vane in the path of the current of air produced by the fan, adjustable stops for moving the said vane alternately into operating position, in the same plane, on either side of the center of the fan, and for regulating the distance of the oscillation.

5. The combination with a fan, of means, for causing it to oscillate as it rotates, comprising a vane in the path of the blast produced by the fan, means for moving the said vane alternately into operating position, in the same plane, on either side of the center of the fan, and means for adjusting the vane thereby regulating the speed of the oscillation.
6. The combination with a fan, of means, for causing it to oscillate as it rotates, comprising a vane in the path of the blast produced by the fan, adjustable stops for moving the said vane alternately into operating position, in the same plane, on either side of the center of the fan, and for regulating the distance of the oscillation.
7. The combination with a fan, of means, for causing it to oscillate as it rotates, comprising a horizontal sleeve in substantially the same vertical plane as the center of the fan, a vane loosely mounted in said sleeve, stops on either side of the center of the fan, and a projection carried by the vane for engaging with the said stops to move the vane alternately into operating position, in the same-plane, on either side of the center of the fan.
