HISASHI KAYASHIMA AND TOTARO MIYA'IA, OF NEW YORK, N. Y.; SAID KAYASHIKL ASSIGNOR TO SAID TOTARO MIYATA.

LAMP. I

.while adapted for Various other uses such as an advertising medium, primarily is designed for household uses, by reason of its illuminating function, and also because of the ornamental and interesting effects produced thereby.

- The invention has for its principal object to provide a lamp of the character stated herein which is simple in construction, effective in operation, durable in use, and adapted to be made at a comparatively low cost.

With the foregoing, and other objects in view, hereinafter stated, the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically stated,'and illustrated in the accompanying drawings, wherein is shown a lamp embodying the structure of the invention in its preferred form, but it is to be understood that changes, variations and' modifications may be-resorted to without departing from the scope of the invention.

In describing the lnvention in detail ref-.

erence is had to the accompanying drawings, which form a part of this specification, wherein like reference numerals indicate corresponding parts throughout the several views, and wherein: I

Figure 1, is a vertical central section of a lamp embodying the invention.

Figure 2, is a plan of the lamp shown in Figure 1 with the top cap removed.

Fi re 3 is a transverse section taken on the line 3-3 of Figure 1.

Figure 4 is a plan of the bottom of the lamp, and 1 Figure 5, is a vertical section of one of the details of the invention.

As illustrated in the drawings, the lamp is provided with a shade, 1, preferably cylindrical in form, the lower end of the shade being supported upon a base 2.

The base is provided on its bottom with air inlets 3, which are controlled by means of a damper plate 4, having apertures 5 formed therein, and adapted to register with the alr inlets 3 in the bottom of the base, either in whole or in part.

The plate 4 is tom of the base means of a pivot pin 6, whlch may also if desired secure to said plate4 a land operating lever 7 the outer end of which extends beyond the outer margm of the bottom of said base as shown in Figures 1 and 4. I

The base is provided with a side wall 8 and a .top wall 9 having openings 10 formed therein to permit air to pass from the interior of said base to the interior of the shade 1.

An electric lamp 10 is secured to the top wall of the base and wires 11 leading from a source of electric supply pass through an aperture 12 formed in said base and connect cured to the lamp shade, preferably to the lower portion thereof, which may be of any suitable construction, but which as shown in the drawings consists of a band 13, secured to the shade by frictional contact, or otherwise; a wire ring support 14 is preferably connected with said band.

An inner supporting ring 15 is secured to the outer ring 14 in any suitable manner such as by the cross bars 16. The cross bars 16 are preferably formed together with vertical standards 17, the upper ends 18 of said standards being preferably turned inward, and connected with a plate 19 which is provided with an aperture adapted to receive a socket bearing20 closed at its lower end as shown in Figures 1 and 5. y

A rotating shaft 21 is supported at its lower end in the socket bearing 20 and rotates on said bearing.

The upper end of said shaft 21 rotates in, and is supported by, a cross bar 22, the outer ends of' the'cross' bar being secured to a ring 23 which is held in place in the upper portion of the shade by frictional contact, or in any other suitable manner.

A sleeve 24 is shown secured to the upper end of the shaft 21, and a fan 25 is secured to said sleeve. The fan may be secured to the shaft 21 in any other suitable manner, if so desired.

pjvotally secured to the bot- The fan is preferably constructed of blades, having a central disk section, and blade sections 26 lying infthe plane of the central disk section. The blade sections 26, have wing sections 27 formed integral therewith. The structure of the fan may be modified however without departing from the invention.

Branch arms 28 are connected with the vertical shaft 21, by means of solder or otherwise, and figures, emblems or other devices 29, may be supported upon the outer.

ends of said branch arms.

The figures 29 are preferably made of transparent material so that different po-r tions thereof may be differently colored, or if desired the figures may be made of plain colors, or of opaque, nontranslucent material.

Instead of, or in addition to, mounting said figures on branch arms such as 28, figures may be secured directly to the vertical shaft 21, as shown by 30 in Figure 1.

The shade may be provided, if desired, with a top or cap 31 having its lower edge supported upon the upper edge of the shade, and provided with openings or apertures 32 to permit of a circulation of air through the shade. Y

When the lamp is in use, electric current is supplied to the lamp 10 through the wires 11, which may be connected with a lamp. or wall socket. The heat from the globe of the lamp causes a current of air to pass up through the base and shade and out through the apertures of the top or cap of the shade.

The ascending current of air causes the fan to turn with the shaft 21, thereby causing the figures mounted onsaid shaft to turn with the shaft.

The light from the lamp projects a reflection from the figures on to the shade bringing out clearly on to the shade the outlines and coloring of the figures, thereby producing a prett and pleasing effect to the eye. The sha e itself may be decorated w1th any desired designs or color scheme to add to the effect.

What we claim as new and desire to -se-, cure by Letters Patent is:

1. A lamp including a translucent shade, a frame Within said shade, including an outer ring secured to the shade, an inner ring connected to the outer ring, standards connected with the inner ring and having converging upper ends, a socket member connected with the ends of said standards, a shaft having its lower end journalled in said socket member, a fan secured to the upper end of said shaft, arms connected with said shaft intermediate said fan and bearing, emblems carried by said arms, and means for illuminating the interior of said shade. 2. A lamp including a translucent shade, a frame having an outerring connected with said shade, an inner ring connected with the outer ring, standards connected with the inner ring and having converging ends, a bearing connected with the inner ends of said standards a socket member connected with said standards, an upper frame consisting of a ring connected with the upper end of said shade and providedwith an apertured cross bar, a shaft having its lower end journalled in said socket member and its upper end engaging the aperture of said cross bar, a fan secured to the upper ends of said cross bar, emblems connected with said shaft and rotating therewith, and means for illuminating the interior of said shade.

In testimony whereof we have ailixed our signatures.
