Application filed September 28, 1927, Serial No. 222,665, and in Japan October 6, 1926.
fan motor according to this invention, when the fan motor oscillates its head.
Fig. 2 is a sectional elevation of the essential art of this invention, when the motor is in tlie position where the motor rotates its head continuously or intermittently.
Fig. 3 is a plan view of a frictional ring.
In Fig. 1, 1 is a motor held on a vertical spindle 3 in a stand 2. This spindle can freely rotate in ball bearings 4 and 4 provided in the stand, and the motor is clamped on the top of the spindle by means of a screw spindle 5. By unscrewingthis" spindle with its handle 6, the motor. can be adjusted in its angular position relative to the axial line of the stand, as an ordinary fan motor can be done in order to change the horizontal direction of the blow of fan. A cord 7 of leading wires for the motor passes through the interior of the vertical spindle 3, and gets in contact with the outer electric source through slip rings and brushes 8.
The stand is enlarged at its upper end and forms a semi-spherical surface 9. Over the upper opening of the stand is provided a cover 10, which protects the interior of the stand from the entering of foreign matters. 7 The motor shaft 11 is provided with a fan ,at its front end, and the rear end extends backward. A vertical spindle 12 is driven by the motor shaft through a worm and a worm gear, and they are engaged or disengaged by pushing in a knob 13. or pulling out the same as known fan motors are.
A sleeve 14 is provided slidably on the vertical spindle 12. The rotation of the sleeve is prevented b means of a small stud 15, which extends t rough an oblong hole 17 on the sleeve, so that the sleeve 14 can slide axially so long as the stud allows. The
sleeve is maintained in its position by a helical spring 19 resting on a disc or screw 20 which is firmly fixed on the extreme end of the spindle 12, so as to have the spring 19 push the sleeve upward.
On the sleeve 14 is slidably fitted another sleeve 21. This outer sleeve provides thereinsome small balls 18 each being pushed inwards by springs 18, which are located in radial holes perforated in the outer sleeve and are confined therein by screws 16. The outer sleeve increases its diameter at its lower end, and a frictional ring 22 made of rubber or the like is fixed thereon by means of a disc 23 screwed to the lower end of the outer sleeve. The ring 22 can be easily replaced by another ring as shown in Fig. 3 when intermittent rotation is required as described later on.
The lower end of the inner sleeve slidably fits in a hole in the outer sleeve as clearly shown in the drawing. The hole has a polygonal section so that the outer sleeve is rotated when the inner sleeve rotates, which in turn is rotated when the vertical spindle rotates.
The cylindrical surface of the inner sleeve is provided with two grooves 18 and 18",
and the balls 18 are kept in either of them,
so as-to keep the outer sleeve at a'higher position as shown in Fig. 2 or to keep it at a lower position as shown in Fig. '1. When the outer sleeve is kept at the higher position, the frictional ring 22 is in touch with the spherical surface of the stand, and the spring '19 tends to press the ring towardsv the sphericalsurface in order to ensure the frictional contact between the two members.
A stud 24 is screwed on the disk 23, and an end of a link 25 with a universal joint at each end is connected thereto. The free end of the link 25 is, when required, screwed to a, projection 26 on the stand by means of a screw cap 27.
In case the fan motor is to be used so as to rotate its head in complete revolution, the outer sleeve should be placed at the higher position and the free endof the link 25 should not be connected with the projection 26, as shown in Fig. 2. If the knob 13 is pressed down, the vertical spindle 12 is engaged with'the fan shaft 11, and the latter motor head rotates with the vertical spindleq'jo 3 due to the frictional resistance produced between the frictional ring and the spherical surface. The frictional contact of the ring 22 with the spherical surface is always kept in equal manner regardless of the angular position of the head relative to the axial line of the stand.
If a polygonal ring 22 such as shown in Fig. 3 is used in place of a circular ring 22, frictional contact of the ring with the spherical surface is obtained only when each angle of the ring faces to the stand. In this case, the motor head rotates intermittently instead of a continuous rotation.
When the upper sleeve is placed at the lower position, no frictional contact is obtained between the ring and the spherical surface, so that the motor head does not rotate at all while the ring 22 is rotating continuously. If the free end of the link 25 is connected to the projection 26, a complete rotation of the ring 23 has the motor head oscillate in a certain angle as an ordinary fan motor does.
When the knob 18 is pulled out, the motor shaft 11 no longer engages with the vertical spindle 12, so that the motor head neither rotates nor oscillates.
In these ways above described, the fan motor according to this invention oscillates, rotates intermittently or continuously, or fixes its head or direction of blow while the fan is running.
