ABVEFtTlSiNG MACHlNE= Application filed April 12,1906. Serial No. 311,375.

To aZZ whmn it may concern: Be it known that I, EDGAR W. Bnow v, a citizen of the Umted States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Advertising-Machine, of which the :iol-" lowing is a specification.

; My invention consists of a machine which produces an optical illusion of a very novel character and combines advertising matter with said optical illusion, the object of my invention being to provide means especially adapted lorv window displays and for advertising in such a manner as will not fail to attract attention.

The means for obtaining the hereinafterdescribed results produced by my invention will be understood from the following de tailed description, taken in connection withthe accompanying drawings, in which- Figures 1,2, and 3 are views of apparatus used simply for the purpose of illustrating the principle of my inventions Figs. 4: and 5 areside and front view, respectively, 01 a good form of construction embodying thev principles of my invention. Fig. 6 is an end view of member B, shown in Fig. 4. Fig, 7 is an end view of member 0, shown in Fig. 4.

In Figs. 1, 2, and 3, in which similar letters refer to similar parts, Z is'a shaft which re volve's in a bearing in the upper end of standard W. On one end of shaft Z is mounted a transparent plate Y,.while on the other end ismo'unted anon-transparent plate X. Near the circumference oiplat: X are five circular I openings, these openings being of equal size and e ually spaced. 1 On -the transparent plate are shown three series of figures, each series being concentric with the shaft Z, andthe figures of any one series-being of equal size and equally spaced. T is a candle, placed so that the light passing therefrom to plate Y is interrupted b the perforated plate X. This interrupts light will appear to be continuous if the interruptions are sufficiently rapid. The figures on plate Y may be painted thereon, or their degree oi transparency may be greater or less than that of said late Y. f It must be understood that plate simply acts as a carrier for tl e series of figures thereon and] that other figures maybe used.

In the three series of figures shown on plateY it will be noticed that there are four methods equally suitable for carrying said Specification of Letters Patent.

figures in the inner series, five middle series, and six figures i ser es.

When the plataY isrevolvcd at the outer a suitable terrupted, the following-described optical illusion will appear on said plate Y. The middleseries, containing five figures, will a pear to bestationary. The ouhr series, core taining six figures, will appear to revolve in the direction the plate is revolving at one sixth of the speed of said plate, while the inner series, containing four figures, will ap pear to revolve slowly in the opposite dire'c tion from that which the said plate Y is re volving. I account for this effect as follows: There are five light interruptions to each revolution, 01 one-fiith revolution from the time of one dash of light to the following flash of light. terruption of light each series oi-figures on plate Y has moved one-fifth revolution, and the figures are only seen the instant the light strikes them. 'l l rerelors in the middle series,

at the second flash of light the position occupied by the figure which precedes 1t, thus During this period of one-light interruption, or one-fifth revolution, each figure in the outer series oi' six figures will move one thirtieth revolution beyond the figure which precedes it, making this series appear. to move forward one'thirtieth revolution, while in the inner series of four figures each figure advances not quite to the position occupied dicated by the dotted lines. ries of figures it will be noted that during the light interruption between the t "o flashes that a has moved to a, t to t, 0 to c, and so on with the other figures'oi his s ies.

Asthe lightinterruptions and the change of positions .of the figures are so rapid that the eye cannot detect them, it will appear that this outer series of figures is advancm g steadily at only one-sixth of the speed ofplate Y. in the inner series of iigures it will be noted that during the light interruption that although dhas'moved forward to d, e to e, f

to,the appearance will be that f has moved back to e and that e has moved back to d, and m a like manner this entire series of fig ures appears to move slowly in the reversedirectiori from, that in which'the lplate Y is moving.

The operation of my machine is as follows: the pulley J is driven by a belt which is connected with a suitable source of power.

W'hen this pulley is stationary or just starting, the sprin s P cause the centrifugal arms I to cling firm y to the inner surface of flange K. Part C is thus made to revolve, and. the

interrupted. When a predetermined speed has been attained, the centrifugal force breaks the connection between the pulley J and the centrifugal arms I, thus eed of the moving member of the light-interrupter to decrease, and conse quently decreasing the rate of light interruption. When this decrease in speed has continued to a certain extent, the springs P again cause the arms I. to engage with pulley J, and in this manner a continual relative variation of speed is produced between the rate of light interruption and the speed of plate L, which is mounted on pulley J. It would be equally satisfactory to have a uniht interruption and a variation in the speed of plate L My machine may be used without the frosted plate N and the advertising-plate M; but when these plates are usedthey inclose the casing from the front, thereby obscuring from view all moving parts. When these plates are not used, the pptical illusion is seen directly on plate L. hen these-plates M and N arensed, however, then shadows from the series of figures on plate L and shadows from the advertising matter on plate M are cast on the frosted plate N, makroduction of the advertising matter as wel as an exact reproduction of the optical illusion. Advertising matter should be placed on plate n al M in such a position so that it will not con that With the optical illusion in a manner to detract from the eiiect.

My invention consists, broadly, in causing one or more seriesof figures to move in or move across the path of an interrupted light, and I do not desire to limit myself to the particular construction or -...;angement of parts herein shown, since changes therein which do not depart from the s irit of my invention and which are within the scope of the appended claims will be obvious.

' Nhat I claim is 1. In a machine of the class described, a light-interrupter consisting of two members, one a revolving member and the other a stationary member, each member having an equal number of similar openings.

2. In a machine of the class described, a light-interrupter consisting of a stationary member and a revolving member, each member having radial openings.

8. In combination in a machine of the class described, means for producing an interrupted light and figures moving in the path. of said interrupted light, difiierent portions of said figures being spaced so as to cause said different portions to appear to move at diflerent speedsQ 4. In combination in a machlne of the class described, means for producin an meor more series 0 figures terrupted light, one adapted to move in rupted in the relative speed between the rate of ligdit interruption and the speed of the mov ing figures to vary.
