Description

UNITED STATES PATENT OFFICE ROBERT STEEL AND THOMAS P. MGOADDEN, OF PHILADELPHIA, PA.
IMPROVEMENT IN TOY CHROMATROPES.
Specification forming part of Letters Patent No. 170,603, dated November 30, 1875; application filed May 8, 1875.
To all whom it may concern:
Be it known that we, ROBERT STEEL and THOMAS P. McOADnEN, of the city and county of Philadelphia, in the State of Pennsylvania, have invented an Improvement in Toys, of which the following is a specification:
Our invention relates to the combination of a disk having concentric rings with two or more segmental portions of dilferent colors to each, with a plain disk in front of the other, having a segmental portion removed, the two disks turning loosely on the hub of a pulley, which, by means of a band connected with a band-Wheel, is rotated at any desired speed; and as the two disks, by being loose on the hub of the pulley, have no regular velocity and change their speed in relation to each other, different parts of the colored disk are brought to view at different times, and consequently there is an interchange of color in each ring.
In the accompanying drawings, Figure l is a front view of the improved toy. Fig. 2 is a side view of the same.
Like letters of reference in both figures indicate the same parts.
A is a shaft, which is held in the hand by means of the handle a, or which may be connected with a stand or any other convenient object to hold it in the desired position. Projecting outward at right angles from the shaft A is a short shaft or spindle, B, on which is a pulley, O; and at a suitable distance from the shaft B is a like shaft, B, on which the bandwheel D revolves, which, by means of the band E, revolves the pulley 0. On the outer end of said pulley there is a hub, 12, on which the disks F and Or have a loose connection and are caused to revolve, being carried forward by the friction of the hub with their center holes, but subject to a change in their relative velocities with each on account of their-looseness on the hub. The disk F has concentric rings formed of segmental portions 0, as shown in Fig. 1, which are of diiferent colors. The disk G has a segmental portion between the lines (1 d removed, whereby a portion of the disk F is always exposed to view but, in consequence of the varying positions of the two disks in respect to each other, caused by their varying velocities above described, different parts of the disk F'are in succession exposed to view. Consequently there is an appearance to the vision of concentric colored rings, which vary in their colors as there is a change produced in the relative position of the reduced plain disk G and the colored ring-disk F. One or more concentric openings, 6, are in the colored disk F, to produce the appearance of a disconnection of the wheel. These may be omitted, if desired. 4 We are aware that tops and other spinning toys with colored disks are old; but
Whatwe claim as our invention is- The toy herein described, consisting of the disk F, segmental disk Gr, pulley O, huh I), and band-wheel D, all constructed and arranged to operate substantially as and for the purpose set forth.
ROBERT STEEL.
THOS. P. MOOADDEN.
