INDOOR PORTABLE OSCILLATING DRIER Filed May 26, 1950 ERNEST K. F CHON BY AT To RN evs Patented Nov. i3, 1951 UNITED STATES PATENT OFFICE INDOOR PORTABLE OSCILLATING DRIER Ernest K. F. Chun, Honolulu, Territory of Hawaii Application May 26, 1950, Serial No. 164,461
1 Claim. 1
This invention relates to drying apparatus, and more particularly to an oscillating drier which is electrically operated.
A main object of the invention is to provide a novel and improved electrically operated, indoor drying apparatus which is very simple in construction, which involves relatively few parts, and which is very simple to operate.
A iur-ther object of the invention is to provide an improved electrical drying apparatus which is very inexpensive to manufacture, which is sturdy in construction, which is dependable in operation, and which may be employed to dry a plurality of different articles of clothing or the like, or for drying objects which would be adversely affected by exposure to ordinary sunlight.
Fur-ther objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:
yFigure l is a side elevational view, partly broken away, of an improved drying apparatus constructed in accordance with the present invention;
Figure 2 is a vertical cross-sectional view, somewhat enlarged in scale, taken through the base portion of the improved drying apparatus of Figure 1;
Figure 3 is a cross-sectional view taken on line 3 3 of Figure 2;
Figure 4 is a schematic wiring diagram showing the electrical connections of the improved drying apparatus of Figures 1 to 3.
Referring to the drawings, II designates a circular base plate, and I2 designates a cylindrical housing secured on the base plate. Designated at I3 is a flanged cap member which is threadedly engaged with the top portion of the housing I2 and deiines a top wall for said housing. Secured inside the housing are a plurality of angle brackets I4, and mounted on said angle brackets is a supporting disc I5. Secured centrally to the disc I5 is a bearing collar I6, and rotatably positioned in said collar is an upstanding sleeve member I'I which extends rotatably through the top cover I3. Secured in the sleeve member I'I is a flexible metallic conduit I8, and secured to the end of the conduit I8 is the electrical lamp socket I9. Mounted in the socket I9 is the infrared lamp 20. Designated at 2| is an electric cord whose conductors are connected to the socket I9, said cord extending into the housing I2 through the conduit I8 and through the sleeve I'I.
Designated generally at 22 is an electric motor which includes a eld coil 23 and an armature 24, said armature being rotatably mounted between the horizontal supporting plate I5 and the laminated iron support member 25 shown in Figure 2, said support member being connected to the plate member by depending vertical bolt elements 26. The coil 23 is mounted on the laminated iron support member 25 and is arranged so that magnetic flux from the coil causes the armature 24 to rotate.
Secured to the sleeve I'I is the horizontal crank arm 2l, and secured to the top end of the shaft 28 of the armature 24 is another crank arm 29. The ends of the crank arms 21 and 29 are connected by a horizontal link bar 30. The crank arm 29 is relatively short as compared with the link 30, and is arranged so that rotation of the shaft 28 oscillates the end of the crank 21 through a relatively wide angle.
Designated respectively at 3| and 32 are switches mounted on the housing I2, said switches being connected respectively in the energizing circuits of .the lamp socket I9 and the motor 22, as shown in Figure 4. Referring to Figure 4, it will be seen that the line cord 33 has one of its conductors 34 connected respectively to the lamp socket I9 and the motor 22 with the switchesI 3| and 32 in series with the respective connections, Therefore, the lamps 20 and the motor 22 may be independently controlled by means of the respective switches 3l and 32.
In operation, the flexible conduit I8 is adjusted so that the lamp 2t is directed toward the objects to be dried, the extent of excursion of the lamp being regulated by the point at which the flexible conduit I8 is bent. The lamp 2l) may be energized by closing the switch 3|, and to oscillate said lamp the switch 32 is closed to energize the motor 22.
It will be readily apparent that the infrared lamp 20 may be swung back and forth at a relatively wide angle of excursion, and that the radius of oscillation of the lamp may be readily regulated by forming the bend in the conduit I8 at a desired location. The device may be employed as a sun lamp as well as for drying garments or other objects, and may be employed for drying garments which cannot be exposed to ordinary sunlight for fear of fading or for other reasons.
While a specific embodiment of an improved electrical heating apparatus has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of 3 the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.
What is claimed is:
A rotatable drier comprising a vertically disposed cylindrical housing having a removable top wall, brackets mounted on the inside surface of the side wall of the housing and projecting radially inwardly therefrom, a supporting disc seated in va horizontal plane on the brackets, an electric motor depending from said disc and having an armature shaft rotatably disposed through the disc and arranged in a verticalplane. an upstanding tubular member rotatably disposed through the top wall of the housing, a bearing Y red lamp, a first horizontal crank arm disposed in said housing and secured to said tubular meinber, a second horizontal crank arm secured to the shaft of the motor above the disc and a horizontal link operatively connecting the crank arms.
