PATENT QFICE.
DANIEL L. WEB/DZ, OF FERGUSON, MISSOURI, ASSIGNOR TO WAGNER ELECTRIC GOR- PORATION, 01? ST. LOUIS, MISSOURI, A. CORPORATION OF DELAWARE.
.MOTOR FAN.
Application filed May 11, 1925. Serial No. 29,321.
My invention relates to a motor fan and particularly to constructional details thereof which lessen the cost of manufacture and improve the operation and appearance. My in'iproven'ients relate chiefly to means for connecting the motor bracket to the base and removably retaining the motor in the bracket.
In the accompanying drawings, which illustrate my invention, Figure 1 is a side view of a complete fan; Figure 2 is a sectional view along the line 22 of Figure 1; Figure 3 is a sectional view along the line 3- 3 of Figure 2; and Figure 4 is a side elevational view of a portion of the oscillation mechanism.
The base 1 of the fan has its top bifurcated and the semicircular portion 2 of the motor bracket 3 tits in the space between these ends, being pivoted to the base by means of the hinge pin l. The screw clamp 5 carried by the base and bearing upon the. lower part oi the portion 2 of the motor bracket serves to clamp the bracket in any desired tilted position with respect to the base. To the motor casing 6 is secured the motor spindle 7 extendin into an opening formed through the lower portion of the bracket, and the spindle is provided with an integral collar 8. The hinge pin is held in place by means of a plug 9 in threaded engagement therewith, this plug being drilled out to form a bottom bearing for the motor spindle 7 and itself being held against lateral motion by being positioned in the lower end of the opening through the motor bracket.
B y the means justdescribed the hinge pin l: is securely held in place and against lat eral play without the use of any external clamping screw and by means not visible in usual positions of the fan.
The tan may be oscillated by mechanism connecting the motor shaft with the motor bracket This mechanism, in the particular iian shown, comprises the oscillating arm 10 connected at one end to the rotatng member 11 driven by the tan shaft and at the other to the motor bracket by means oi the pin 12. As shown in Figure 3, the end oi the oscillating arm 10 attached to the motor bracket is so shaped that a portion of this arm extends over the collar 8 on the motor spindle when the arm is in its operative position and serves to prevent the separation of the motor and base when the tan is lifted by the motor or "tan guard. However, when the arm 10 is released from its connection to the member 11 itmay be rotated on its pivot into a position in which no part of it extends over the collar 8, and the motor spindle may be inserted or removed irom the bracket.
The construction just described obviates the necessity of drilling and tapping a hole in the motor bracket and providing a screw to hold the motor spindle therein.
Having fully described my invention, what i claim as new and desire to secure by Letters Patent oi the United States is:
1. A motor mounting comprising a base. a bracket member, a spindle carried by the motor casing and seated in the bracket, a pivot pin extending through said bracket and having bearings in the base, and means for retaining the pivot pin against lateral motion with respect to the bracket and base, said means comprising a. plug fitting into an opening in the bracket and engaging with the pivot pin, said plug being adapted to also form a bearing for the lower end oil the motor spindle.
2. in an oscillating fan, the combination ot a mounting bracket, a motor spindle rotative therein and provided with a retaining shoulder, and an oscillation arm connecting the motor to the bracket, said arm having a projection adapted to cooperate with said shoulder to retain the spindle in the bracket.
3. In an oscillating fan, the combination of a mounting bracket, a motor spindle rotative therein and provided with a retaining shoulder, and an oscillation arm pivoted to the bracket and having a portion eX- tending over said retaining shoulder in assembled relation of the parts but out of engageme-nt with said shoulder when the arm is rotated on its pivot to a non-operative position.
In testimony whereof, I have hereunto set my hand this the 5th day of May, 1925.
