The' Schedule referred todn these Letters Patent and making part of the esame.

To all whom it may concern.-

Be it known that I, SMITH W. ANDERSON, of the city, county, and State of NewYork, have invented a new and improved Ghameleotrope; and I do hereby declare that the followiu g is a fullfclear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings'fhrming part of this speci' cation, in Which- Figure l represents a plan or top View, partly in section, of my improved chameleotrope.

Figure 2 is a vertical transverse section of the same taken on the plane of the-line :c x, fig. l.

Figure 3 is a detail plan viewpoi'apart of the same. Figure 4 is a detail side viewof a double disk suport. Similar letters of reference indicate corresponding parts.

The object of this invention is to produce a spinning toy 'which will exhibit in constant variation a beautiful array of colors.

The invention consists iu the employment of a holder or support, which will retain a colored disk eccentric to the- 'rotating shaft on 'which the said holder is secured. l

' The invention also consists in connecting tbe said shaft vby suitable gear connection `with a hand-lever, so that its revolutions may b e unequal, being produced by muscular power.

The colored disk theshaft is, bythe unequal revolution of the same, turned 'on'its' own axis so. as to thereby constantly change'v the color which is above the center of the shaft.

The blending together of the colors produces.very beautifulvetfects. lhe independent .motion given .to the disk is necessary, because if the samewould merely revolvecoucentrically around the shaft, its colors would blend into one shade, while the vmere eccentric rotation would not show the desired variations.

A, in the drawing, represents a vertical shaft hung in a frame, B, and connected by suitable gear-wheels a a with a larger toothedwheel, b, that is hung loose upon a shaft, G.

suspended `on an eccentric arm'of The shaft C carries a ratchet wheel, c, into which a pawl, d, pivoted t0 the wheel b engages.

D is'a lever-'projectingr from the shaft G.. By oscillating it the wheels will be revolved in one direction. When the lever is carried back the pawl slips on the ratchet.

A ily-wheel, E, is mounted upon the shaft A to gather and equalize the power. ever, never quite equal, as it would be if the shaft was revolved by other than muscular power.

To the upper end ofthe shaft is secured, or on it is formed a hook-shaped holder', F.

The same serves to support a disk or plate, G, the surface of which is divided by radial lines or other- .wise into diiierently colored spaces.

The book supports the disk eccentric to the shaft A, and therefore one of 'the colored sections is inthe center of rotation-not the real center, where all colors converge.-

The constant shifting'of the disk on the holder produced by the unequal motion of the shaft, causes a constant change of color to take place, and during the changing a very beautiful blending together of the several colors.

v The` holder may he double-hook shaped, as in fig. 4, to hold adisk, H, and a colored ring, I, in separate centers, orftwo disks or plates, as may he desired.

Fig. 1 shows several of the disks and a ring, I, placed in a box formed by the frame B. Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- 1. The holder F, secured upon a rotating shaft, A, for the purpose of holding a colored disk or plate in an eccentric position to produce a varying display of colors, as set forth.

2. The combination of the lever D with the shafts C and A, and with the holder F, all arranged to pro The motion is, how-
