SPECIFICATION forming part of Letters Patent No. 782,498, dated February 14, 1905. Application filed April 11,1904. Serial No. 202,481.

To all whom, if may concern:

Be it known that \vc,GHARLES R.G ROFF, Sr. Cuantas R. GROW, Jr. and LESLIE G non?. citizens of the United States of America. and residents of Whitebear, in the county of Ranisey and State of Minnesota, have invented certain new and useful Improvements in Advertising-Signs, of which the following is a specification. Our invention relates to improvementsin ad .fertising-signs, and has for its object eil'ect- 'e means for illuminated advertising which aresimple in construction and operation and brilliant intellect. g To these ends our invention consists of a suitable inclosure having an illuminating-sign and means for changing the colors of said sign. .ln the accompanying drawings, forming part of this specification, Figure 1 is a sectional view in elevation of our invention. Fig. '2 is a view looking at the back of the inclosnrc when the door is open. Fig. 3 is a front view. Fig. 4 is a view of the multicolor screen, showing the color-pieces removed. Fig. 5 isa sectional view of said screen. Fig. 6 is a sectional view of an alternate construction, and Fig. 7 is a sectional view of Fig. 6

on the line X X.

reflector b v means of; a socket 13. Arevolu` ble multicolor-screen' Gis positioned between the open end of the main reflector and the outerF end of the auxiliary reflector, where it In the drawings, let A represent a suitable inclosure havingl an illuminating sign-plate 2 in one end. This sign-plate' has an .opaque ground `and translucentletters 3. Located in said inclosure is a main reflector B, which is made of tin or other suitable material, having walls 4, which converge toward an open en 5. The larger end of this reflector is shaped to fit within the sides of said Ainclosure and rest against the sign-plate. The reflector is formed with flat segmental surfaces 6, which are adapted to sharply rellect the light against the sign-plate. Back of the reflector is a door 8, which is hcld'closed by means of an crdinary catch. (Not shown.) An'auxiliary reector 11 is fastened Ato the door, and an electric lamp 12 is mounted within said auxiliary is revolved by means of the clockwork mech- 56 anism D, (of ordinary construction and supported by brackets 7.) carrying the drive- -shai't 15, on'wlnch said screen 1s mounted.

This color-screen consists of a circular frame Y 14 andradiatlng arms 20, between which col- 55 ored segments F, of glass, mica, or any othet` transparent or translucent material, may be` mounted in .the slotsll. As shown, the segmental openings between some of the arms are leftopen or partly open, so as to produce diflerent color efl'ects upon the sign. An electric switchl is also carried by the shaft 15 and consists of a circular insulating-block 17, supporting commntator-scgments 18, which are electrically connected with said shaft. A

brush 19,' fastened to the support 10, sweeps the segments as the switch 16 rfcvolvcs. 'The main reflector is. provided with a horizontal partition Q2 between the words or letters of the sign` and the segments in the frame 14 are 70.v

formed with sections 21 of different colors. Partor all of the sections of any segmentmayl be omitted, so that the color of the light will be varied on thcdiilcrent sides of the partition in the main reflector, thus producing contrast and greater diversity of colors between the words of the sign.

The lamp and switch areA shown connected in Fig. 1 tliag1:tii1niatically with the electric circuit 23, which leads from the socket tothe' 80 brush, thence through the segments of the switch, clockwork mechanism, and the electric generator E and back to the socket and' lamp. The segments of the switch and multicolor-screen are positioned so that the lamp -is switched on or off successively as the screen revolves, the light being reflected through the 'opcnin g .against the sign when the color-seg- Vmcnts are fully interposed between the reflector and the opening and turned oil' when 9o the bars 2O are in front of said opening and the segments moved out of effective position.

I In operation the'color-screen is revolved at a low rate of speed.

It is obviocs that the partition 22 need not 95 be used unless desired or that a number of partitions may be used and' the arrangement of the color-screen changed, also that a gas or other side, means for changing the coiors of light thus cast, and means colors of light to sharply define on said sign-plate.

, 18. A device of the class set forth, consisting of an inclosure A, an illuminated signplate 2 in one end tiiei'eof, a main reector B their position in said inclosure having walls 4 which converge toward an open end 5, a door 8 in said inclosure back of seid reiectoi', an auxiliary reiiector 11 'asteiied to said door, an electric lamp 12 mounted within said auxiliary refcctor, a revoluble mLiiticolor-screen C between the open end of said main refiector and the outer end of said auxiliary reecrior, clockt'or separating said work mechanism Dattached to said screen to revolve the same, en electric switch 16 con.- nected to said screen, :in electric circuit connected with said lamp and switch. and a ion, in said mein i'eliectoi',

gitudinal partition 22 for the purposes specitied.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
