ADVERTISING DEVICE.

To all whom it mwy concern: Be it known that I, NIKOLAUS S'ITPKO- WITSCH, painter, a subject of the Kin of .tion is an advertising. device preferably in the form of letters r signs and the like which is formed of indivldual deep prismatic reflectors provided with sources of light, so that advertising signs and the like are fective both byday and night.

In order that the invention may be clearly understood, reference will be made'to the accompanymg drawing in which two embodiments are represented by way of example and in which:

Figure 1 represents in front ele'vation'a prismatic reflector of glass. a sectional elevation through the same. Fig. 3 illustrates same in side elevation. Fig. 4: is a side elevation partly broken away showing the combination of the reflector'with an incandescent lamp and its attachment on a plate. Fig. 5 re resents in slightly perspective view a fimshed .lettercomposed of a plurality of reflectors with incandescent lam s and a casing, and 6 illustrates in sectlonal elevation. a modi d form of reflector.

Similar characters of reference denote like parts in all the figures.

Each individual, device or letter is composed of single deep prismatic reflectors having an inner hollow space which is adapted to lodge a small incandescent lamp and outside a multiple of refracting surfaces of which for instance four are shown in the device illustrated in Fig. 5. These single prismatic members are suitably supported in ame work conforming m shape 'to the de-- sired devices. By virtue of these deep rismatic reflectors the daylight is as wel reflected producing then a shining and attractive appearance. At n'i ht the artificial light, that is the small incandescent lamp Specification of Letters .Patent. Application filed September 21, 1908. Serial No. 454,010.

produced which are almost equally ef Fig. 2 is Patented Feb. 2 2, 1910.

I within the cavity of each prismatic reflector 1s llkewlse reflected whereby an attractive device is produced. Thus the device forming thesubject matter of this invention is highly effective both in day time as well as at night, a eculiarity which has heretofore, to the'know edge of applicant, not been produced.

Referring-to the drawing, advertising letters are made in the following manner: A letter which is of like form and size as the advertising letter which is to be made is (flit out of a thin plate a of iron, for exam- P sary for attaching it to a support, whereupon the reflectors 0 each provided with a lamp 7) in, a holder 6 are mounted on the late in such manner that the desired letter is made. The whole device is finally attijacheg in a casing '01, as clearly shown in The letter R of Fig. 5 is shown-as a specimen because in.,it the shapes of the deep and is provided with the holes necesi prismatic four-sided reflectors occur which are necessary for composing straight, round and slanting parts of letters.

provided with a thin layer of metal, preferably gold, on their exterior.

The advertisin letters comprising deep rismatic glass re ectors and sources of light in the same have the following advantages (1-. During the day they appear as shining lass letters, look superior and are very striking on account of the many reflecting surfaces. b. When illuminated by their sources of light they appear as sharply defined,

highly illuminating and readily legible letters. c. The number of incandescent lamps required is about half that'necessary when letiters are demarcated by incandescent lamps on y. p

What I claim as my invention and desire to secure by Letters Patent is z p 1. An advertising letter composed of a multiple of deep prismatic hollow glass reflectors having straight inner surfaces and curved outer surfaces, and a coverin of shining metal on said curved outer sur aces I As a rule the glass reflectors are c0l0red*or 2. 'An' advertising'letter composed of a frame conforming 1n sha e to said letter, a

multiple of deep prismatic hollow glass reflectors having each four straight, reflecting inner surfaces and curved outer surfaces covered with gold, and an incandescent lamp in each of said reflectors, said arran ement 10 reflectini both day light and artificia light so that t e letter is br lliant at all times.

Signed at Berlin, Germany, this 2nd day of September, 1908.
