JOHN STU'RTON EWART AN D WILLIAM 'ERN 'EST CLIFTON, OF'NOTTINGI-IAM, ENGLAND.
(GRANTED UNDER To all whom it may concern:
Be it known that we, JOHN SEWART and WILLIAM E. Cnrrrorr, subjects of the King of Great Britain, residing .at Nottingham, England, have invented certain new and useful Improvements in Chromatropes (for which we have filed applications in Great Britain on January 1, 1919, and on, April 3, 1919, on which we have obtained a single patent, No. 136,923), of which the following is a specification.
This invention relates to chromatropes which are chiefly used as toys, but which are also useful in determining the effect of mixtures of colors when in motion; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a front view of a chromatrope constructed according to this invention. Fig. 2 is a vertical section through the device as shown in Fig. 1. Figs. 3 and 1 are a front view and a section similar to Figs. 1 and 2, but showing a modi fication. Figs. 5, 6, 7 and 8, are front views of subsidiary disks showing various arrangements of color patches. Fig. 9 is a front view of a transparent chromatrope adapted 0 forms a guide for the subsidiary disks,
and retains them in one plane while the main disk is being revolved. A bar B of wire is provided and has pivots B formed on its ends which are passed through the holes B and through holes in the main disk C, and which have end portions bent around parallel to the bar so as to secure, the bar to the main disk. The pivots B fit the holes in the main disk C, but the holes in the sub sidiary disks are larger than the pivots B, so that the subsidiary disks are free to slide upon the face of the main disk to a predetermined extent in all directions.
The subsidiary disks have patches of color a on,their exposed faces Z2, and the patches may be varied in shape and in color as hole in the the main disk C is mounted Specification of Letters Patent. Patented June 2'7 1922 Application filed me 2, 1919. Serial No. 301,170. run raovrsrons OF THE Aer or MARCH 3, 1921, 41 STAT. 12., 1313. I
-Whenused as a toy, a applied to the middleof and passes through the center main disk, and the device is adapted to be twirled by hand by means of this twisted cord.
In the modification shown in Figs. 3 and 4, the hook-shaped end portions of the bar are pasesd through the main disk in the reverse direction from that shown in Figs. 1 and 2, and they have non-circular shutters D mounted on the pivots B. The shutters partially cover the subsidiary disks, and they have large center holes similar to those of the subsidiary disks. When the main disk 0 is twirled first in one direction and then in the other direction, the colors of the patches are blended, and at eachchange of speed and direction the disks A are moved to a different position eccentric of thelr pivots, and are frequently partially revolved on the pivots, so that a great variety of color effect is obtained.
In Fig. 5 the color patches 0 are circular. In Figs. 6 and 7 the color patches 0 have extensions 0 In Fig. 8 two plates E and F are shown having color patches 0. These plates are used in place of the disks A, and they have large holes G, and are movable on the pivots B in a similar manner to the plates or disks A, and may also be revolved with respect to each other.
In the device shown in Figs. 9 and 10, on a shaft J secured to a plate K carried by a frame L, and is driven by means of a grooved driving sheaveC or in any other approved way. NVhen the device is used with a projecting lantern the plate K and the color patches on the disks A are formed of transparent material, and openings C and C are formed in the main disk C behind the color disks A.
What we claim is:
1. In a chromatrope, a main disk pro vided with means for revolving it, pivots which revolve with the main disk and which project laterally of it at predetermined distances from its center, and subsidiary disks provided with color patches and having center holes of larger diameter than the pivots, which holes engage slidably with the pivots and permit the subsidiary disks to move to positions eccentric of the ivots.
2. In a chromatrope, a main disk having a much as desired.
twisted cord.- H is the 2 bar B central hole, a bar secured crosswise of the said hole and havlng pivots at its ends arranged at predetermined distances from the center of the main disk, subsidiary disks middle part of the said bar and extending through the center hole of the main disk.
In combination, with a chromatrope as set forth in claim 2, non-circular shutters having holes similar to the subsidiary disks, said shutters being mounted on the said pivots and partially covering the subsidiary disks and being movable in a similar manner to them and independently of them.
In testimony whereof We have signed our names to this specification in the presence of tWO subscribing Witnesses.
