W. P. OWENS STREET SIGN AND LIGHT Filed oct; 25, 1929 115] perforate metal signs disposed in angular Patented May 13, 1930 PATENT OFFICE WILLIAM P. OWENS, OF CRESCO, IOWA STR-EET SIGN AND LIGHT Application led October 25, 1929. Serial No. 492,473.

This invention relates to combination street signs and street lights especially adapted to be mounted at the corners of intersecting streets.

It is an object of my invention to provide an extremely simple, highly efficient street sign and light which will be plainly visible night and day to indicate intersecting streets, which may be manufactured at low cost and which may be illuminated economically.

At the present time,.most cities are equipped with ornamental street lights at the corners of city block and the identification of intersecting streets are usually indicated by imrelation at the head of the device and below the illuminated globe. At night when the device is illuminated, it is practically impossible to read the names of the streets,

since the light shines from above and the rays of light are not thrown against nor do they permeate the sign portions of the device. n

It is a further object of my invention to provide a combined street light and illuminated street indicating sign, wherein the names of the streets will be illuminated and plainly visible at night by the same source of light which is radiated from the globe of the device.

These and other objects and advantages of the invention will be apparent from the following description made in connection with the accompanying drawings wherein like referencey characters refer to similar parts throughout the several views, and wherein,

Fig. l is a. view mostly in vertical section of a preferred embodiment of my invention, some portions of the device being shown i front elevation;

Fig. 2 is a cross section taken on the line 2 2 of Fig. l; and i Fig. 3 is a corner View of a modified form of the invention applied to crossed signs indicating intersecting streets.

In the form of the invention illustrated in Figs. 1 and 2 of the drawings, an enclosed casing is provided, fixed to the upper end of a tubular ornamental post or standard P, which may be of any suitable construction.

My said casing comprises an invertedtruncated pyramidal base 4 which is preferably constructed of metal and which has a rectangular upturned flange 4fL at its upper edge. The lower end of base member 4 is welded or otherwise rigidly affixed to a relatively heavy attachment sleeve 5, as shown, said attachment sleeve having an inverted skirt 5a to which the lower edge of the base is secured. As shown, sleeve 5 is provided with a depending enlarged socket 5b which telescopes over the upper end of post P and is secured thereto in suitable fashion by means of heavy set screws 6.

My said casing also includes a truncated lower portion of top 7 I provide a rectangular 7 shaped angle member 8, which may be welded or otherwise rigidly secured to the inner surface of top 7 having a depending vertical flange 8a, which is disposed inwardly of and in parallel relation to the depending flange 7a of the top. A series of upright angle bars 9 are rigidly connected at their upper ends to the inside corners of rectangular flange 8a and at their lower ends to the inside corners of the flange 4a of the base, i

thereby rigidly connecting the top and base of the casing. Base 4 is provided at each of its upper edges with an upturned vertical lip 10, which has an angularly disposed attachment portion 10iL welded or otherwise secured to the outer and upper portion of the base. Lips 10 are vertically alined with the flange 7a of top 7 and in -cooperation with flange 4aL of the base to form a series of four horizontal guides, one disposed at each side of the casing for insertion of a street indi'- cating sign or plate. Oppositely disposed guides 8b of Ushaped cross section are provided in the lower edges of the top, one at each facade of the device and may conveniently be formed integrally with the angle member 8, if desired.

I utilize sign plates which have opaque portions and also translucent portions whereby the characters or letters may stand out fili sharply and be observed at night by illumination of the interior of the casing. As shown in the drawings, the sign plates 11 are constructed of sheet material and have cut out stencilled portions representing the char-v acters or letters. Behind each of the sign plates 11 I prefer to utilize sheets of translucent but not transparent material 12, such as for example, white or Colored Celluloid, thus, making it possible to illuminate the letters and characters although preventing the interior of the device from being seen through plates 11 and also keeping out rain, snow and dirt. The sign plates 11 and sheets 12 are slidably disposed in the sign receiving guides, a pair of which are provided at each side of the casing. Thev vertical corners of the casing are closed lby suitable angle strips 13 which may be bolted or otherwise detachably secured to the flanges 7fL and 10.

At the upper end ot the top 7 of my casing, a grooved globe receiving ring 14 is provided having a lower, conical, internal surface which may be rigidly allixed to the upper edge of top 7 The groove 14 is open the upper edge of the ring and is adapted to receive a depending annular edge of a suitable ornamental globe (il. Detachable means, such as set screws 15 may be provided in the outer flange of ring 14 which may engage the telescoped edge of the globe to retain the same against displacement. Ring 14 is preferably provided with a series of inclined drain ports 14b which communicate with the bottom of groove 14@ to drain off any water which may accumulate in said groove. An elongated vertical tube 16 is adjustably secured within attachment sleeve 5, the lower end of said tube being snugly telescoped within said sleeve and adjustably connected thereto by suitable means, such as the set screw 17. An electrical lamp socket 13 is detachably secured in the upper end of tube 16 and is electrically connected with service wires 19, which extend through post P and through the tube 16. A powerful electric lamp 2O is secured in socket 18 and the tube 16 is preferably so adjusted that the filament of lamp 2O is disposed at, or slightly below, the upper peripheral edge o'l" the truncated pyramidal top 7, the round portion of said electric lamp being disposed partially within the globe Gr and .partially within my said casing.

t will be apparent that light will be distributed upwardly flooding globe G, certain rays being deflected Ato some extent by the tapered attachment portion of the globe while a large amount of light will be directed downwardly and reected by the truncated pyramidal top 7, thoroughly illuminating the `interior of the casing and the sign plates at the various facades thereof. The external surface of sign plates 11 are preferably painted some `color which contrasts with the color of the translucent sheet 12 so that the names if/repie of the streets may be easily read in the daytime when the device is not illuminated. At night with the electric lamp illuminated, the letters or characters on the various sign plates will stand out prominently and can be" observed from a considerable distance. The light rays emanating from the globe will not be directed downwardly tendingto obscure the reading of the signs and the entire source of light will be furnished for both the street light and the sign devices by means of the single lamp 20.

The device is constructed throughout to avoid entrance of rain, dust or snow into the casing and it will be seen that the top of the casing is completely enclosed and that water cannot accumulate in the ring 14. It will also be seen that connections between the top and the base of the casing are such that there can be no accumulation of.' water and the lower guides for the sign plates are preferably provided with drain ports.

ln the modified form of the invention shown in F ig. 3, two crossed casings A and B are provided preferably being of generally rectangular shape but having segmental tops. Casings A and B are secured together with their center lines crossed according to the angulation of intersecting streets where they are utilized. Sign plates 11 similar to Vthe sign plates previously described may be applied at the longitudinal sides of casings A and B and may be detachably secured in place by angle members or plates 21. The central portion of the base of casing A and the center portion of the top of casing B ar welded or otherwise secured together and are also apertured, as shown in Fig. 3 to accornmodate the upper portion of an electric lamp 22. Lamp 22 'may be suitably mounted in an electrical socket (not shown) provided in the base of lower casing B. The lamp is so disposed that it will etliciently illuminate both casings A and B, the filament being preferably disposed in line with the attached portions of said casing. This form of the invention may be used for corners of intersecting streets where lighting is not 6especially required.

From the foregoing description it will be seen that l have provided an extremely simple but highly eflicient street sign and light adapted to be readily applied to ornamental lamp posts now utilized in many municipalities and adapted to clearly display the names of streets or other indicia in the daytime and at night. It will also be apparent that a considerable amount of light is emanated from the sign portion of the device as wellas from the lighting globe at the .top of the casing. In actual use, the device has proven highly etlicient for lighting as well as for indicating the street.

It will, of course, be understood that various changes may be made in the form, details,
