PAUL .E'Nezsow A T TOPNE YS United States Patent 3,206,744 SEMAPHORE LIGHT Paul E. Nelson, Rochester, Minn. (405 Kiowa Place, Boulder, Colo.) Filed June 11, 1963, Ser. No. 287,074 7 Claims. (Cl. 34tl-378) This invention relates to a new and very useful construction for a semaphore light.
The education of smallchildren in our complex society today must include training in traflic rules and regulations. There has been a long-felt need in the art for a simple semaphore construction which can be used in classrooms for demonstrating and educating youngsters in the elementary but vital safety procedures they must observe at intersections, etc.
Accordingly, it is an object of this invention to provide a reliable, simply made semaphore device adapted for use in classrooms in teaching young children traffic safety procedures.
It is another object. of this invention to provide a semaphore construction which employs light transmissive and opaque plastic shapes which can be readily and conveniently fabricated by modern molding techniques, especially vacuum molding.
It is a still further object of this invention to provide an apparatus which is easily maintained, rugged and well designed for use as an educational tool.
It is another object of this invention to provide a semaphore construction which is suitable for use inside buildings at corridor intersections and the like, for regulating and controlling traflic flow.
Other and further objects of this invention will become apparent to those skilled in the art from a reading of the following specification, taken together with the drawings wherein:
FIG. 1 is a perspective view of a semaphore light constructed in accordance with the teachings of this invention;
FIG. 2 is an exploded view in perspective of the top portion of the embodiment shown in FIG. 1;
FIG. 3 is a vertical sectional view taken along the line 3-3 of FIG. 1;
FIG. 4 is a horizontal sectional View taken along the line 44 of FIG. 1; and
FIG. 5 is a schematic diagram of a circuit suitable for use in the embodiment shown in FIG. 1.
Turning to the drawings, there is seen in FIG. 1 a semaphore construction of the invention, herein designated in its entirety by the numeral 10. The semaphore employs a pedestal or base 11 upon which is vertically mounted a supported column 12. On the upper end of column 12 is vertically positioned the semaphore lighting system which is herein designated in its entirety by the numeral 13.
This system 13 is seen to consist of a housing 15. The housing 15 has a plurality of vertical sides, though the embodiment shown employs four sides designated, respectively, as 16, 17, 18 and 19. Each side 16, 17, 18 and 19 defines a plurality of vertically aligned apertures. Thus, in the embodiment shown, each side 16, 17, 18 and 19 has three apertures; an upper aperture designated in each case by the numeral 20, a middle aperture designated in each case by the numeral 21, and a bottom aperture designated in each case by the numeral 22.
Four light transmissive lens panels, each designated by the respective numeral 23, 24, and 26, are provided. These panels, 23, 24, 25 and 26 are each constructed of a self-supporting light transmissive material, preferably of a plastic material, such as Celluloid. Each lens panel 23, 24, 25 and 26 is adapted to align with and fit against the inside face of a different one of each of the sides, respectively, 16, 17, 18 and 19. Each of the lens panels 23, 24, 25 and 26 in the region where it aligns with individual ones of the apertures 20, 21 and 22 in each associated respective side 16, 17, 18 and 19 is provided with a raised area so that, relative to the exterior of the housing 15, the individual lens panels 23, 24, 25 and 26 are generally concavely protruded through the individual apertures 20, 21 and 22. Thus, when viewed from their front side, each of the lens panels 23, 24,. 25 and 26 has three convex protrusions designated in each case by the respective numerals 27, 28 and 29. The lens panels 23, 24, 25 and 26 with their respective convex protrusions 27, 28 and 29 can be conveniently made by vacuum molding procedures well known to those of ordinary skill associated with the art of plastic fabrication. Situated behind each lens panel 23, 24, 25 and 26 is an opaque reflector panel which, in the embodiment shown, are each numbered, respectively, as 31, 32, 33 and 34. Each reflector panel 31, 32, 33 and 34 is adapted to align with and fit against the inside face of a different one of each of the lens panels; in the embodiment shown, these are, respectively, the panels 23, 24, 25 and 26. Each of the reflector panels 31, 32, 33 and 34 define, in combination with the adjacent lens panel convex protrusions 27, 28 and 29, an enclosed cavity designated in each case, respectively, by the numbers 35, 36 and 37. Each of the reflector panels thus defines the side walls and base of each cavity 35, 36 and 37.
Because, in the embodiment shown, the depth of each of the respective cavities 35, 36 and 37 is such that the cavities would normally not fit in the interior of the housing 15, the lateral side edges of each base portion in each cavity 35, 36 and 37 are flattened at a 45 angle relative to the front face of each reflector panel 31, 32, 33 and 34. In all cases, this flattened 45 face is designated by the numeral 38. Thus, when the reflector panels 31, 32, 33 and 34 are all mounted in back of their respective lens panels 23, 24, 25 and 26 in housing 15, the flat faces 38 permit the reflectors 31, 32, 33 and 34 to be contained in the housing 15 without forcing or otherwise distorting the cavities 35, 36 and 37 in each panel 31, 32, 33 and 34, respectively.
The bottom of housing 15 is closed and serves as a base on which the housing 15 can be mounted so that the semaphore 13 can have a vertical position in space. The top of the housing 15 is capped by a removable roof or cap element 14. This roof 14 is equipped with a pair of downwardly extending flanges 39 which are so positioned on opposite sides of roof 14 as to permit the roof 14 to fit on the top of the housing 15 with the flanges 39 positioned adjacent the inside face of opposite side walls 16 and 13, respectively. Then, through a pair of holes 40, one adjacent to top edge of each side wall 16 and 18, respectively, a pair of machine screws or the like are extended into appropriately formed threaded holes 41 in the flanges 39. It is through the top of the housing 15 that the lens panels 23, 24, 25 and 26 and the reflector panels 31, 32, 33 and 34 are inserted in assembling the semaphore 13.
In order to provide realism in the semaphore system 13, each of the apertures 20, 21 and 22 in each side 16, 17, 18 and 19 is provided in the assembled semaphore system 13 as shown in FIG. 1, with a hood 42 which circumferentially extends outward from the associated side walls 16, 17, 18 and 19, respectively, around the upper side edges of the apertures 20, 21 and 22. The hoods 42 are conveniently attached to the housing 15 by any conventional means such as welding or the like.
In the uppermost portion of each cavity 35, 36 and 37 in each panel 31, 32, 33 and 24, respectively, is a small hole numbered, respectively, 43, 44 and 45. These holes 43, 44 and 45 are adapted to receive an assembly comprising a small electric light bulb 46 and an attached socket 47. The bulb 46 slips through each hole 43, 44 and 45, respectively, and screws into the base of the socket 47. Each of the bulbs 46 is connected by wires into an electric circuit, which will be described below.
Each of the panels 23, 24, and 26 in its respective lens region 27, 28 and 29 is colored red, yellow and green, respectively, so as to reproduce the colors used in traffic signal controls. The coloration can be achieved by any conventional coating procedure, such as silk screening, spray painting, brushing, or the like, so long as the coating of paint applied does not reduce the light transmissive properties of each lens region 27, 28 and 29 to the point of opacity. Thus, each transparent lens panel 23, 24, 25 and 26 can be painted by solutions of organic dyes in an organic solvent. For example, a band of red dye can -be placed across the uppermost portion of each panel 23, 24, 25 and 26 as shown by the dotted line portions on panel 23. Then, across the middle is deposited a band of yellow dye and across the bottom, a band of green dye.
Although any conventional electrical system can be employed, the system used is generally one which sequentially lights individual ones of the bulbs 46 so as to communicate signal information through individual ones of apertures in the housing 15 of the assembled semaphore system 13. Thus, the embodiment shown in the figures employs an electro-mechanical system which employs a repeat cycle timer 63. The timer 63 is a conventional and generally commercially available combination of a motor 48 with a rotor having a plurality of axially spaced circumferentially extending contact timing strips 49, 5t), 51, 52, 53 and 54. The rotor 30' is shown as being journalled on a shaft 55 for common rotation therewith. As the timing strips 49-54 revolve in response to rotation of motor shaft 55, the strips 49-54 come into contact with individual ones of brushes 57, 58, 59, 60, 61 and 62. As each contact is effected, a circuit is completed. Thus, the repeat cycle timer 63 having the motor 48, the strips 49-54, the brushes 57-62 is a multi-contact timer and can be conveniently mounted in the base 11 of semaphore 10 as shown in FIG. 1. It may be here noted that a cam operated timer device such as the Bristol Repeat Cycle Timer, series RCT-lOO may be utilized to accomplish the same objective as the above-described type of timing device. The interconnection of the bulbs 46 with the timer 63 is shown more particularly by the schematic wiring diagram of FIG. 5. As shown in this diagram, the four bulbs 46 are mounted in each cavity behind each convex lens protrusion 27, 28 and 29, respectively, and are electrically connected together in alternate pairs. Similarly, each of the bulbs 46 in cavity 36 behind each of the convex lens protrusions 28 is connected to each other in alternate pairs and finally, each of the bulbs 46 in the cavity 37 located behind each of the convex lens protrusions 29 is connected together in alternate pairs. Each alternate pair of bulbs 46 is connected in parallel within its respective circuit. The cavities 35, 36 and 37 are indicated collectively in the diagrammatic view of FIG. 3 by the dotted line outlines.
For convenience, each face will be referred to by the directions north, south, east and west as labeled in FIG. 5. The arrangement is such that one filament terminal of each bulb is connected to a hot side of the supply lines 65 by means of a hot lead 66. A branch of the -hot lead 66 leads directly to the motor 48. In the diagram shown, the hot lead 66 can be considered as the negative line. The positive line 68 connecting with the source wires 65 is connected to both the drive motor 48 and to the shaft 55 of the rotor 30. The shaft in turn is connected to each of the strips. The branch of the positive line 68 leading to the motor 48 is equipped with a switch 67. Similarly, the main portion of line 68 before branching is equipped with a switch 69. Thus, when switch 69 is closed, power is supplied to each of the bulbs 46, to each of the brushes 57-62 and to the motor 48 through a switch 67. Switch 67, an on-olf switch for motor 48, enables one to freeze or hold the signal light lighting sequence at any given position, as for instructional purposes in a classroom, etc. Circuits between individual ones of the bulbs 46 and each of the brushes 57-62 are completed by appropriate wires so that when the strips 49-54 on the rotor 30 are rotated to complete contact with the brushes 57-62, the appropriate circuit is selectively closed so as to light selected alternate pairs of the bulbs 4. The lighting sequence in the diagram shown in FIG. 5 is such that the yellow east and west lights have just gone out and the red north and south lights have just lit. Similarly, the red east and west lights have just gone out and the green east and west lights have just gone on. The yellow north and south lights are not lit. It will be appreciated that the green lights are on for a shorter interval of time than the red light, owing to the fact that the yellow lights are allowed to light for a few seconds of time after the green lights expire and before the red lights come on in each of the directions north, south, east and west, respectively.
