ELECTRIC SIGN.

Specificationof Letters latent. Patented O t 11 1921 Application file'd'November 12, 1920. Serial No. 423,590.

To all to 7mm it may concern Be it known that I, MA'r rHnw J. Cannon, citizen of the United States, and resident of New York, in the county of New York and State of New Yorlg have invented certain new and useful Improvements in Electric Signs, of which the following is a specification. I I This invention relates generally to Aid vertising devices and particularly to the kindlniown as illuminated signs.

The objects of my invention are to provide an inexpensive sign having readily ex changeable characters for the purpose of varying the wording, and means whereby the expense of illuminating the sign 1s reduced to a minimum.

Another object of this invention is to provide in connection with such a sign two sets of adjustable reflectors, one of which being adapted to reflect the light from the light source in a substantially vertical plane toward the sign characters} the other set adapted to reflect the light from top and bottom toward said characters. Another object of my invention is to provide in connection with such reflectors, means whereby the latter may be adjusted at desired angles respective to the characters so as to utilize the light of the light source at maximum efliciency.

The foregoing and still further objects will be fully understood from the following description and the accompanying drawings forming part of this specificatlon and in which:

Figure l is a front elevation of a sign showing the exchangeable characters.

Fig. 2 is a sectional view therethrough taken on line 2-2 f Fig. 3. i

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Fig. dis a sectional elevation taken on line 4-4 of Fig.1. i Fig. 5 is a detail view showing the arrangement of a transverse member supporting a substantially vertically disposed rewhich are provided supports or guides 2 for glidably engaging sign characters 3. These characters may he slid from either side of the casing. By changing these characters various 'words may be formed.

The character plates are preferably made of solid, non-transparent bases, from which are cut out the desired characters. The cut out portion is preferably filled with a transparent substance as glass. porcelain or the like, indicated at a. At the bottom of the casing, and disposed centrally between its sides, a'longitudinal guide 5 is provided wherein ride adjustable sockets 6 in which a light source 7 is mounted. At the top and bottom in near proximity to the characters. a set of longitudinal parallel guides 8 are provided wherein slide, by means of guide bars 9, vertical or transverse connecting members 10. Adjustably mounted upon the latter are reflectors 11 provided at their center with a swivel joint 12 forming part of a tubular member 13, which may slide upon vertical connecting member 10 and can be attached thereto atany position by means of thu1nb-screw 14. Due to the swivel joint connection, the reflectors, which are preferably cylindrically curved, may beset at any desired angle respective to the characters 3. Reflectors 11 are'substantially parallel with the long side of the characters. Parallel to guides 8 is a set of longitudinal connecting members 15, u 30H which are glidably mounted sleeves 13, provided with a set screw let and a swivel joint 12 which support another set of cylindrically curved reflectors 11.

The latter are preferably disposed substantially parallel with the short side of the characters 3 and may be set at any desired angle respective to the latter.

A preferred form of mysign is shown in the drawings where the light source is disposed centrally between two pairs, of opposite" disposed characters so that the light source is intermediate between at least two adjacent characters at each side of the sign.

. ue vertical reflectors are preferably disposed near the extreme long sides of the two adjacent characters so as to throw the light in a substantially vertical plane against the latter. Theupper and lower reflectors 11 are inclined to concentrate the light against their respective characters from top and bottom, and for this purpose they are somewhat inclined toward each other as shown in Fig. In this manner a sign unit of two respectively four characters is created, lighted by one light source.

Y the light from top and bottom toward the respective upper and lower halves of the characters, In this manner the light is directed through the transparent-part 4 of the characters thereby causing the latter to be visible at dark.

It is obvious that the drawings represent merely preferred forms of construction of my device, and that modifications or changes may be readily made within the broad scope of my invention. In view of the fact that signs are built for various requirements, I reserve for myselfthe right to make such changes as will be necessary to simplify their manufacture and modify their form and construction in accordance with such re quirements.

Having thus described my invention, I claim:

1. A sign, comprising in combination, a

casing, exchangeable, transparent characters arranged at both faces thereof, means for supporting said characters, a set of longitudinal parallel guides disposed in pairs at top and bottom and extending over the entire length of the casing, transverse connecting members ghdably associated with sa1d guides, cylindrically curved reflectors adjustably mounted upon said connecting members and adapted tobe'set at any desired angle respective to said characters, a set of longitudinal guide members disposed in pairs at top and bottom of said casing, a plurality of cylindrically curved reflectors adjustably mounted upon said members and adapted to be set at any desired angle respective to said characters, an adjustably mounted light source arranged at the bottom of said casing, said first mentioned reflectors being disposed in such a way as to reflect the light from said ource in a substantially vertical plane toward said characters, the latter mentioned reflectors adapted to reflect light from the top and bottom toward said characters.

2. An illuminated sign, comprising in combination, a casing having open sides, exchangeable characters adapted to close said open sides, a light source disposed near the bottom of the casing intermediate between said characters, a set of longitudinal guides at top and bottom of said casing,

transverse connecting members adjustably mounted in said guides, cylindrically curved reflectors disposed substantially parallel with the long side of said characters, adjustably attached to said connecting members and adapted to be set at any desired angle respective to said characters, a'set of longitudinal guidemembers disposed at top and bottom within the casing, a plurality of cylindrically curved reflectors slidably attached thereto and adapted to reflect light from top and bottom toward said characters, substantially as described.

3. An illuminated slgn, comprising in combination, a casing, exchangeablecharacters at both sides thereof, an adjustable light source within the casing, a set of adjustable, substantially vertically disposed reflectors, aset of adjustable, substantially horizontally disposed reflectors, both sets of reflectors grouped within the casing and adapted to reflect light from the light source in a substantially vertical plane and from top and bottom, respectively, toward said characters. i

4;. In an illuminated sign, a casing, transparent characters at both sides thereof, an adjustable light source within the casing centrally disposed between two opposite pairs of said characters, adjustable reflectors provided at the outer length sides of each pair of characters, adjustable reflectors provided at top and bottom of each individual character, said reflectors adapted to reflect the light from the light source, respectively, in a substantially vertical plane, and from top and bottom toward said transparent characters.

5. An illuminated sign, comprising in,

combination, a casing, a slidably mounted adjustable light source, a groupof transparent characters disposed at two sides thereof, a set of reflectors disposed at both longitudinal sides of each of said character groups, a set of other reflectors disposed at top and bottom of each'individual character, both sets of reflectors adapted to reflect thelight from the light source toward said characters.

6. In a sign, an exchangeable transparent character, an adjustable light source, a set of substantially longitudinally disposed reflectors, anotherset of substantially transversely disposed reflectors, said reflectors grouped and set around the character and adapted to reflectthe light toward the characters, respectively, from both sides, the top and bottom.
