Qriginal application filed January 7, 1913, Serial No. 740,641. Divided and this application filed October 9, 1917. Serial No. 195.497.
To all whom it may concern:
Be it known that 1, CHARLES H. J. DILG, a citizen of the United States, residing at the city of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Motor-Fans, of which the following is.
a full, clear, and exact description. I My invention relates to motor fans and particularly to motor fans of the oscillating type, this application being divisional of my a plication Serial Number 740,641, filed Jiinuary 7, 19-13.
Une object of my invention is to provide a motor fan which may be easily converted from an oscillating to a non-oscillating fan, and vice versa. Another object is to prevent injuring the motor when any unusual opposition is ofiered to the oscillation. Other general objects are simplicity and durability of construction, convenience in manipulation, and reliability in operation. Still other objects and advantages of my invention will appear from the following description.
In accordance with my invention, 1 provide in the oscillating train which operatively connects the motor shaft with a stationary abutment on the base, a clutch designed to automatically disengage under excessive back pressure on the oscillating train, as when an obstructionis encountered by the fan guard, and render the oscillating train inoperative, thereby converting the fan quickly and automatically into a nonoscillating fan. Specifically this is effected by a slidable shaft which carries one element of the clutch and is resiliently held in its position of clutch engagement, the clutch elements being designed to separate when they are subjected to relative movement. My invention also comprehends manual means for effecting the same operation. My invention also comprehends various other features of construction and arrangements and combinations of parts, as will hereinafter more fully appear. i
I shall now describe the illustrated embodiment of my invention and shall thereafter point out my invention in claims.
Figure 1 is a side elevation of a complete fan embodying my invention;
Fig. 2 is a longitudinal sectional elevation of the rear portion of the same, on an gplarged scale;
Fig. 3 is atransverse sectional elevation on line 33 of Figs. 1 and 2;
Fig. 4 is a detail face elevation of the striated clutch wheel;
Fig. 5 is a similar view of the coiiperating crank disk; and,
Fig. 6 isa detail, partially in rear elevation andpartially in section, of the cranklocking disk and cooperating parts.
In the illustrated embodiment of my invention an electric motor is employed which is mounted upon a base 1 and carries a fan 2 of suitable construction upon the front end of the armature shaft 3 in the usual manner. The base 1 is provided with an upwardly extending motor-bearing stem or arbor 4, and the motor casing 5 is provided on, its under side with an integral cylindrical bearing head 6 which has a cylindrical socket fitting upon the upper end of .the stem 4 for rotative movement thereon, and which bears at its lower end upon an adjustable collar 7 supported upon a shoulder on the stem 4. A locking screw 8 in the bearing head 6 engages in a circumferential groove in the stem 4 and locks the motor against movement longitudinally of the steml An anti-friction bearing is interposed at the upper end of the stem 4. To oscillate the motor upon this bearing means are provided actuated from the armature shaft 3, as will now be described.
A crank member comprising a crank disk 9 is fixed on the end of a horizontal axially slidable shaft 10 mounted below the armature shaft 3 in suitable bearings in a gear casing 11 on the rear of the motor, and on its inner face this crank disk 9 is provided with a plurality of beveled clutch teeth 12 adapted to engage in striations 13 on the adjacent face of a gear clutch wheel 14.- which is loosely mounted on the axially slidable shaft 10. A coiled spring 15 is disposed between the clutch wheel and crank disk and tends to separate them, but with the shaft in the position shown in Fig. 3,
the two clutch members are held together against the expansive pressure of the spring 15. The clutch Wheel 14 is actuated from the armature shaft 3 through reduction gearing comprising a worm 16 on the rear end of the armature shaft, a worm wheel 17 on one end of the stub shaft 18, and a pinion 19 on the other end of the stub shaft 18 and meshing with the clutch wheel 14. Through these transmitting means the clutch wheel 14 is continuously rotated by the motor, and, when the crank disk 9 is in engagement with the clutch wheel 14, it is also rotated by the motor.
To axially slide the shaft 10 and move the crank disk 9 into and out of engagement with the clutch wheel 14, manually operative means are provided comprising a stud or shaft 20 disposed at right angles to the slidable shaft 10, and having a knurled knob 21 on its outer end, and a crank or eccentric pin 22 on a head on its inner end extending into a circumferential groove 23 in the slidable shaft 10. The shaft 20 bears in a plug 24 and a coiled spring 25 is disposed between the plug 24 and the head on the end of the shaft 20, and holds the pin 22 in the groove 23, while permitting the shaft 20 to yield longitudinally. The engaging faces between the knob 21 and the plug 24 are preferably striated to securely lock the knob in adjusted position. It is now apparent that the turning of the knob 21 serves to adjust the slidable shaft through the engagement of the crank pin 22 in the groove 23, and to thereby throw the crank disk 9 into and out of engagement with the clutch wheel 14..
To lockthe crank disk 9 against rotation when out of engagement with the clutch wheel, a lock disk 26 is provided on the op posite end of the shaft 10, which is provided with a plurality of socket holes 27 near its periphery adapted to engage with a spring pressed pin 28 in the casing 11, when the shaft 10 is moved to disengage the crank disk. The spring permits the pin 28 to yield until it drops into one of thesocket holes 27 The crank pin 29 for the crank disk 9 is mounted on a crank member consisting of a disk 30 pivoted eccentrically upon the crank disk 9 and so arranged that the center of the crank disk 9 is in the path of rotation of the crank pin 29. On the periphery of the eccentric disk 30, suitably spaced locking notches are provided into which a spring pressed locking pawl 31 is arranged to engage. A knob 32 on the eccentric disk 30 affords convenient means for manually rotating the eccentric disk to vary the eccentricity of the crank pin 29 and thereby vary the throw of the crank pin, the locking pawl 31 serving to lock the eccentric disk-in adjusted position. It is evident that if the eccentric disk is adjusted to bring the crank pin 29 concentric with the crank disk 9, the throw of,the crank pin will be zero.
To mechanically connect the crank pin with a fulcrum or stationary abutment to impart oscillation to the motor as the crank. is. actuated, a'connecting rod 33 is employed, which at one end has a pivotal and swivel connection with the crank pin 29, and at the other end has a similar connection with a lug 34 on the adjustable collar 7 The adjustment of this collar adjusts the fan relative to the base, as is apparent, and per mits the breeze to be sent in any direction without altering the position of the base 1 relative to its support. A set screw 35 locks the adjustable collar 7 to the motor-bearing stem 4 in adjusted position.
The striated engaging faces between the crank disk 9 and the clutch wheel 14, being beveled or inclined, co-a'ct to spread the two members apart if any excessive load is placed upon them, as occurs, for example, when any unusual opposition is offered to the oscillation, as when an obstruction is placed in the way of the fan guard. If the crank disk is held against rotation, the rotative effort of the clutch wheel 14 causes the striated clutch face to act as a cam on .the teeth 12 and force the crank disk and slidable shaft 10 to the left, thereby rotating the-shaft 20 and the knob 21, which is permitted by the striated engaging faces between the knob 21 and the'plug 24, the shaft 20 y elding longitudinally against the tension of the spring 25. In this way the oscillating mechanism is automatically disengaged and the motor prevented from becoming overloaded and possibly burned out when oscillation is prohibited. When the obstruction has been removed, the knob' 21 may again be turned back and the oscillating mechanism thrown into operation.
It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described within the principle and scope of m invention. v v
