Application filed June 19,1922. Serial no; a
To all whom iamag camera:
Be it lmown that I, Josnrn NOFF, a citizen of the United States, and resident of the city of New York, borough of :n-
c hattan, county of New York, and State of New York, have invented a new and Improved Fan, of whichthe following is a full, clear, and exact description.
My invention relates to a to provide certain new and useful fan, and aims improvements in connection with a device of this character.
It is an object of the present invention to provide a fan which is movable with re- 5 s ct to a suplporting element, so that a b ast of air m be directed in various directions.
It is a further object of the present invention to construct a fan which will involve a mechanism permitting of its moving with respect to a supporting element for the purpose set forth in the preceding paragraph, but in which a further means will be provided which will serve to prevent this movement.
Another object of the present invention is that of constructin a device of the'character stated which 'w' l preferabl employ a plurality of fans, and means or driving the same, which latter means may be actuated to operate all of the fans synchronously, or to permit of an actuation of one or more of the same independent of the others.
Still another object of my invention is that of roviding a fan in which the angle at whic the blast of air is delivered may be varied according to the desire of the operator.
Among further objects of my invention are that of providing a fan embed ing a relatively simple construction caps. le of being placed on the market at a nominal figure, the fan proper being adapted to be positively moved with respect to the supportin element therefor.
Wit these and further objects in mind my fan consists essentially of a motor, and a support for the motor, together with a fan, and means connecting the fan with the mo- 59 tor, the said fan proper being capable of being moved with respect to the motor mounting. .7
Reference is had to the attached sheets of drawings as illustrat one practical bodiment of my, invention, and it will be seen in these views that;
'Figure 1 is a sectional side elevation of a fan embodying my improved construction.
Figure 2 and Figure 3 are sectional plan views taken along the lines 2-2 and 3-3 and in the directionof the arrows indicated in Figure 1.
Figure 4 is a transverse sectional view taken along the line 44.- and in the direction 3f the arrows also indicated in Figure i Figure 5 is a fragmentary sectional view of a detail Eof the operating mechanism forming a art of my im roved construction and ta en along the ine 5--5 and in the direction of the arrows indicated in Fi re 2. 1 v
11 these views the reference numeral 11 indicates the motor which may be of an desired type and construction and which 1s enclosed within a supporting housing 12, a gear housi 13 being formed adjacent the outer end 0 the housing 12 and being rotatably su ported thereby, by any suitable means suc as that of providing an outwardly extendin annular-flange 14 adjacent the upper e go of the housing 13, and the provision of a ring plate 15 atithe lower end of the housing 12, and extending in wardly therefrom, thus providing a ball race within which an annular series of balls .16 may be disposed to freely permit of the turning of the housing 13 with respect to the housing 12.
New with a view of positively. rotating one housing with respect to the second of the same it will be noted that I referably form teeth 17 in the upper edge 0 the housing 13, and these teeth in aggregate provide an annular rack which is enga ed by the teeth of a gear 18 carried by the ousing 12. The shaft 19 of the motor is extended into the housing 13 and its body carries a worm 20 with which a worm wheel 21 co-operates. This latter element is mounted upon ashaft 22 which in turn carries a gear 23 and the latter meshes with the gear'18 so'that upon the motor shaft 19 bein rotated, the worm 20 and the sh 22 wil be accordingly rotat/ed, thus causing a corresponding movement to be transmitted from the '2 .23 to the ar 18 and thus to the rash provided by the teeth 17 so that the operates at h motor 11 will cause the housing 13 to be posigig'ely rotated with respect to the housm ow with a View of providing means which will serve to prevent a movement of the housing 13 with respect to the housing 12, if an operator desires to prevent this action, it will be seen that one end of the shaft 22 is supported upon a crank 2 1lying within the housing and having its outer end extending beyond the same, whereby upon the arm 25 being rocked the crank arm W111 be correspondingly moved thus oscillating one end of the shaft 22 incident to the provision ofa ball and socket support 26, at its opposite end. In this connection attention is invited to Figure 5 which shows in full and dotted lines, respectively, the position with which the wheel 21 may assume with respect to the worm 20 and it will be obvious from these views that an operator may cause the crank 24 to assume a position which will cause a positive cooperation between the wheel 21 and the worm 20, but 11 it being desired to prevent a rotation o the housing 13 with respect to the housing 12 a shifting of the crank 24 will achieve the result desired in that it causes the worm wheel 21 to move out of engagement with the worm 20 or in other words, to the osition shown in dotted lines in the view a orereferred to. 7
It will further be seen that the motor shaft 19 carries a crown gear 27 and a plurality of brackets 28 are associated with the housm 13 in a manner hereinafter describe to support fan shafts 29 in suitable bearings provided for this purpose. These shafts carry adjacent their outer ends suitable fans 30 and incident to the association of burr gears 31 with the opposite ends of each of these shafts, and the co-operation of these latter gears with the crown gear 27 it will be obvious that upon the motor 11 being actuated that the crown gear will efiect an operation of the fans 30 to produce blasts of all.
If it is now desired to dispose one or more of the fan shafts 29 at an angle with respect to the axis of housing 13 different from that shown in Figure 1 this may be accomplished due to the peculiarity of the bracket mounting. In other words it will be noted that each of the brackets 28' is provided with a slotted portion 32 in its base and extendin through this slotted portion is a shank o a wing bolt 33, which latter has the inner end of its shank screw threaded, and associated with the said housing 13. Thus due to the fact that the lower end of the housing 13 is curved, and further for the reason that the inner contour of each of the brackets 32 corresponds to the outer contour of this curved portion, one or all of the brack ets can he slid downwardly or moved upmea er wardly by simply releasing its associated clamping member i. e. the bolt 33, and swinging the bracket to the position desired subsequent to which the same can again be affixed to the housing 13.
This action of the parts will not however cause a breaking of the driving connection existing between the motor shaft 19, and the shafts 29 due to the provision of the burr gears 31 and the crown gear 27. Thus it will be obvious that a swinging of any one of the shafts 29 with respect to the housing would merely result in the teeth of the gear 31 being slid with respect to the teeth of the gear 27 so that this portion, in angularity to the shafts 29 and 19 will not in any way'interfere with the driving of the former from the latter. It is also to be noted in this connection that an efiicient support for each of these shafts and each of its saddle members 3 1 are swingingly carried at a point 35 by the brackets 36, it being noted that this point of connection, which may be established by suitable pins, is in line with the center of the burr gear. Thus each of the shafts 29 will be efiiciently supported by a saddle member 34 in addition to the brackets 28, and a disengagement of the gears 31 and 27 is rendered impossible by virtue of the support provided at their inner end by the saddle member 34 and the brackets 36.
Finally with a view of permitting any one of the fans being cut off from operating without in the least affecting the operation of the remaining fans it will be seen, as in Figures 1 and at, that each of 'the brackets 36 is carried by a preferably screw threaded stem, 37 cooperating with a similar screw threaded opening in the housing 13, so that if the operation aforementioned is to be accomplished this may be achieved b simply moving one of the stems 37 to rop the bracket 36 associated therewith, to thus cause a disengagement of the teeth of the burr gear from the teeth of the gear 27.
Thus all of the objects of my invention have been accomplished and it will further be understood that numerous modifications of structure: might readily be resorted to without in the least departing from the scope of my claims; which are;
1. The combination of a plurality of fans disposed at an angle to each other on horizontal axes, an electric motor arranged with its armature shaft vertical for rotating all the fans, controlling devices for inclining one or more of such axes from the horizontal at will, and controlling devices for operatively disengaging one or more of said fans from said actuating means at will.
2. The combination of a plurality of fans disposed at an angle to each other on horizontal axes, an electric motorearranged with fans, means for relatively redisposing the axes of said fans without discngagin said actuating means, and means for re isposing the axis of one of said fans to disengage 5 said actuating means from the last-mew tioned fan.
3. The combination of a plurality of fans disposed at an angle to each other on horizontal axes, an electric motor arranged with 10 its armature shaft vertical for rotating said fans, means for relatively redisposing the axes of said fans without disengagin said actuating means, and .means for re sposing the axisof one of said fans to disengage said actuating means from the last-mentioned fan, both the two means last mentioned inc-ludin 'in common a toothed gear driven by sai actuating means and a toothed gear fixed relative to the fan last mentioned.
JOSEPH ARONOFF.
