This invention pertains to fan oscillating mechanismsuch as is used in small ventilating fans to vary the direction of the delivery of airwhile the fan isrunnmg.
able` to vary the extent ofthe swing of the fan, and it is further desirable to'be able to make the adjustmenttherefor while the fan,
is running. In the usual practice the arL rangements for-adjusting` vthe-thi-'ow of the fanare located beneath the 'motor frame,k
usually under the motor bearing and'vadjacent the moving connections between theYos-l cillating mechanism and the fan base. Such" an arrangement is'objectionable on accountof the'fact thatthe rmechanism is usually providedl with vlubricating devices containing l'oilforgrease and, since the manipulative parts'v fory adjustment are below, "the`re 11s often a leakage ofoil orgrease *whichV vcovers these lparts so Aas to soil the fingers when handling, With this location fof vmanipula- Figure 1 is a sectional view of fan oscillating mechanism embodying` this invention, taken Von 'line 1 1, Figure 3;
Figure 2 i'sian end view of the on line 2 2, Figure l1; o
Figure 3 isa section on line 3 3, Fig ure 1; and y Figure 4 is a bottom view of the adjusting head. Y v Y Referring. tothe drawing 1 designates the frame of the fan' motor. This may be mounted :forv swinging movement as by swiveling on a shank2 working in astationary base 3 in any well known manner. Thev motorl shaft works in a bearing 4 vand may beuprovided with a rear lextension 5 havinga worm 6 engaging a worinwlieel 7l same taken In such a mechanism it is desirable tobe means of this pin and on a transverse shaftl fixed to a hollow vertical shaft 11. These parts mayI be enclosedin a housing-12 having a vertical bearing 13in which the'shaft 11 moves. The housing 12 is adapted to re-'v ceive oil lor grease 4for Y lubricating the contained nmech'anism,
-The shaft 11 carries at its lower` end a head 16 recessed to receive an adjusting plate 17. The shaft' 11 but to a through the hollow cap14 to the voutside of :the `housing above the same where it is y I lative button 19. and the stem 18 fixed thereto and also fixed, the platef'l will be 'turned for presently.
Mounted onthe and-vin engage-i:
ment with the plate 17 is a carrier 20. This carrierispivoted at 21 to the-'head lf'and is provided with a radial slot 22 adapted to be'engaged by a pin`23fixed to and projectmg downwardly from the kplate 17. By slot connection, the carrier 20hmay be moved fromv side toside byproperly rotating the plate 17 Vby manipu lationk of the spindle 18. The carrier 2O and the plate 17 are held inplaceby'a cap 24 fixed tothe head 16, fas by pin 25, vand provided with a' curvedslot 26 in which' a crank pin 27 `mounted vonl the carrier v20 may move when the 'carrier swings on its pivot 21.y It will be seen, therefore,- thatl by manipulation of the button 19, the carrier 20y may be swung back and forth from side to side yon the head 16. AThe crank pin 27fis mountedon one` side of the carrier so that movement of Asaid carrier to'one sidewill movethe'crankpin out to the extremei'rim of the head 16 while movement in the opposite direction will bring the crank pinsubstantially into alinement with the shaft 11. It willbe seen, therefore, that this carrier and its pin 27 providea crank of variable throw according' tothe adjustment of the plate 17. y
The Crank pin27 may be connected by a y y 'and may be provided with a suitablek cover 14 Yfixed in place by a1,
equipped with a mvanipu-l. By turning the buttonv 19 y extendingl downwardly to the'plate'17tofwhich it adjusting the lrank as will be described l 8 carrying a second worm 9 engaglnga second worm wheel 10.
A plate 17 is not-,fixed to the stem" 18 passing upwardly shaft 11 and through Vthe -will also be slow so changing the length it at vthe center and suitable link 28 with a iixed pivot 29 on the base 3 so that rotation of the shaft 11 Will operate to swing the fan from side `to side through an arc depending on the adjustment of the crank pin 27. A detent engaging suitable notches in the plate 17 is adapted to yieldingly retain said plate in adjusted position.
In the operation of this device the motor, throughthe agency of the gearing 6, 7, 8, 9 and l0, drives the vertical Vshaft l1 and thereby the head 1.6 in rotation. Said rotation will carry the crank pin 27 in a circular pathso as'to swing the fan back and forth. Since the rotation of the shaft 1l is quite. slow on account of the large reduction ratio of the gearing 6, 7, 8, -9 .and l0, the' rotationof the manipulative ybutton 19 that the butt-on maybe grasped and turned in eitherI direction relatively to the shaft 1l even while the fan is in motion. Said movement of the button 19 will have .the eifect, as :above described of Since the pathof the pin 27 across the head 16 passes through the center of said head, the pin 27 may be adjusted so as to position when so positioned, the fan will not oscillate. i I It will be seen, therefore, that in accordance with this invention` oscillating mechanism is provided in which the manipulating adjusting element is-placed above the head and even above the motor bearing. There is thus no danger of soiling or injuring the lingers during said manipulation.
. It' is obvious that various `changes may be made in details of construction without Vdeparti-ng from the spirit of rthis invention; it is, therefore, to be understood that this invention -is not to be limited to the specific details shown and described.
