PAUL N.BECKA WWW- M ATTORNEYS United States Patent 3,ll85,224 Patented Apr. 9, 1963 3,085,224 SIGNAL CONSTRUCTION Paul N. Becka, 1308 Bunts Road, Lakewood, Ohio Filed Apr. 4, 1960, Ser. No. 19,963 9 Claims. (Cl. s40 s The invention relates in general to signals and more particularly to pedestrian control signals which are easily assembled and disassembled with consequent ease in servicing and repairing the same.

Pedestrian control signals which are in use at the present time are generally mounted on a pole or post at an intersection with the back of the housing which contains the signal components butting up against the post. The electrical circuit components which energize and de-energize the signal lamps are fixedly secured within the housing. Consequently when the signal needs repair, it is difficult, if not impossible, to get at the electrical circuit components without removing the entire signal from its mounting place. If it is possible to gain entrance to the inside of the housing to get at the electrical circuit components, it is generally awkward and difficult to work on the same because of the limited amount of space in which there is to mount the components. It is also dangerous from the standpoint that there is generally no way to disconnect the electrical components from the source of power which is used to energize the signal.

It is therefore an object of the present invention to provide a control signal and more particularly a pedestrian control signal which is easily serviced and repaired without having to remove the entire signal from its mounting place.

, Another object of the invention is to provide a pedestrian control signal which may be opened and entered from the front.

, Another object of the invention is to provide a pedestrian control signal wherein the lamps and electrical circuit components are mounted upon a removable tray which may be removed from the signal in the event they come into disrepair and may be readily repaired.

Another object of the invention is to provide a pedestrian control signal which has a source of electrical energy cooperating therewith to energize the same, with a new and novel switch means for alternatively connecting and disconnecting the source of electrical energy.

Another object of the invention is to provide a pedestrian control signal which includes a housing and a hood, each have complementary mating flanges, with a means for securing a side of each of the flanges together to provide for a lost motion swinging movement between the two to provide entrance to the housing.

Another object of the invention is to provide a pedestrian control signal including a removable tray which carries lamps and the electrical circuit components for operating the lamps, with switch means for alternatively connecting and disconnecting a source of electrical energy and the electrical circuit components which switch means include a fixed part mounted by the housing and a movable part mounted by said removable tray and including a handle for moving the movable part.

Another object of the invention is to provide a pedestrian control signal having a translucent or transparent panel with instructions thereon with a new and novel means for holding the panel in place.

Another object of the invention is to provide a pedestrian control signal with an enclosure member to house lamp means with opposite ends of the enclosure being closed by a transparent or translucent panel and a tray or panel member which carries the lamp means on one side thereof and electrical circuit components on the other.

Other objects and a fuller under-standing of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

FIGURE 13 is a view taken generally along the line 1313 of FIGURE 10.

The control signal of the present invention has been indicated generally by the reference numeral 10 and in FIGURE 1 has been shown as mounted to a supporting post 11. The signal includes a housing 12 which has top, bottom, back, and first and second side walls indicated by the reference numerals 13 through 17, respectively. The housing may also be referred to as having a back wall and four side walls. The top and bottom walls and the first and second side walls of the housing terminate at their ends opposite the back wall 15 to form an open front face on the housing which is generally defined by a flange 20 which extends around this open front face. The signal 10 also includes a hood 23 which comprises an annular frame 24 which has a flange 27 which is complementary to the housing flange 20. Integrally formed with the annular frame and extending therefrom on a side opposite the flange 27 are first and second side walls 29 and 30, respectively, and a top wall 28. Mounted in the annular frame 24 is a transparent closure member 38; for example, constructed of glass or plastic material. When the signal 10 is in use, the hood 23 and the housing 12 are secured together as shown in FIGURES 1 and 3 by bolts '37 which extend through mating holes 66 which are provided in the respective flanges. A sealing member 40 is disposed between the flanges 20 and 27 to provide a tight seal between the hood and the housing. To provide a lost motion swinging movement between the hood and the housing in the event it is desired to expose the interior of the housing, first and second rings 42 and 43, respectively, are provided which extend through the bottom sides of the flanges 20 and 27. This permits the housing to be opened from the front while still preventing complete separation of the hood and housing whereby the hood will never become lost from the control signal. This loose connection which is provided by the use of the rings 42 and 43, respectively, permits the flanges to be adjusted so that the holes 36 match up and so that the bolts 37 may be inserted therethrough to secure the hood in place as shown in FIGURES 1 and 3 for use during operation of the signal.

As best seen in FIGURE 2, first and second brackets 46 and 47 are respectively mounted to the top and bottom walls 13 and 14, respectively, of the housing 12.

A removable tray or panel 50 having substantially the same dimensions as the inner dimensions of the housing is mounted within the housing by the brackets 46 and 47, respectively. The tray is secured to the brackets by means of screw members 48. As will be noted in FIG- URE 3, the brackets 46 and 47 are spaced from the open face of the housing a predetermined distance which is substantially the same dimension as the depth of the removable tray 50. Handles 53 are provided on the tray 50 to facilitate moving of the same. The removable tray 50 is provided with first and second side portions 51 and 52, respectively, and the first side portion mounts a gaseous discharge lamp 55 which is in the form of a continuous luminous tube. This continuous tube, as will be readily recognized, could be a plurality of tubes rather than a single continuous one. The lamp which is carried by the first side portion of the tray, as will be noted, is formed into the words, DONT and WALK. The words, of course, could be different and could convey the same or different messages. The second side portion 52 mounts electrical circuit components which have been referred to generally by the the reference numeral 58. The electrical circuit components and the lamps which are carried by the removable tray might be, for the sake of example, the same as those disclosed in my co-pending United States patent application, Serial No. 653,705, filed April 18, 1957. The electrical circuit components 58 which are carried by the second side of the removable tray are energized and de-energized by an electrical energy source which comes from a traffic controller separate from the signal here shown. This source of electrical energy has been shown in the accompanying drawings as entering the housing by way of three electrical conductors 59, 60, and 61, respectively (FIGURES 3 and 4). Interposed between the electrical circuit components 58 and the electrical conductors which bring in the source of electrical energy is switch means indicated generally by the reference character 62 and best shown in FIGURES 4, 5, and 6. The switch means 62 includes generally a fixed part 64 and a movable part 65. The fixed part 64 includes an insulated mounting strip 66 Secured to the second side wall 17 of the housing 12 by members 67. Mounted to and extending from the strip 66 are three fixed contacts 70. The electrical conduc tors 59, 60, and 61 are each electrically secured to a fixed contact 70 as at 71. The movable part 65 of the switch means 62 includes a bracket 73 secured to the second side of the removable tray 50. Fixedly secured to the bracket 73 is an insulated mounting support 74 from which guide members 75 laterally extend. Three movable contacts 76 which are adapted to engage the fixed contacts 70 are mounted on a slidable member 77 which in turn is guided in its movement by the guide members 75 extending through elongated slots 78 in member 77. Secured to the slidable member 77 is a handle 80 which extends through the removable tray to the first side thereof where it may be readily reached upon gaining access to the housing through the open face. Each of the three movable contacts 76 are electrically connected to electrical conductors 82, 83, and 84, respectively, which in turn are connected to the electrical circuit components 58 which are mounted upon the second side of the IEIIIOV': able tray 50. FIGURES 4 and show the switch means 62 in the connected position and FIGURE 4 shows the switch means in the disconnected position. In the position shown in FIGURE 3, the panel 50 defines a first compartment 89 within which the gaseous discharge tube resides and a second compartment 90 within which the circuit components reside. The gaseous discharge tube 55 which has been shown is supplied with electrical energy at its end portions by means of terminals 85 and 86, respectively, and at its intermediate portion by terminal 87.

In operation, if it be desired to gain access to the interior of the signal as shown in FIGURE 1, it is necessary to remove the bolts 37 which extend through the holes 36 in the flanges 20 and 27. When this has been done, the hood is swung into the position shown in FIGURE 2 whereat the rings 42 and 43 keep the housing and hood from becoming completely separated from each other. The switch means 62 is then disconnected by grasping the handle and pulling outwardly from the position shown in FIGURE 4 to that which is shown in FIGURE 3. The source of electrical energy is now disconnected from the electrical circuit components which are carried by the removable panel or tray. The removable panel can then be easily removed from the housing by unscrewing the screw members 48 which extend into the brackets 46 and 47. The removable panel which carries the lamps and the electrical circuit components may then be carried by the handles 53 and removed and may be immediately replaced by another panel. It will be noted that the handles 53 extend out beyond the extent of the discharge tube or lamp means whereby the panel may be laid on its first side portion while being worked on without damage to the tube. The defective panel may then be removed to a repair shop where it can again be put in working condition without shutting down the control signal. In the event the repairs are not extensive, the defective panel may be removed from the housing and worked on immediately and put back into service with little danger from electrical energy because of the inability to disconnect the signal from the source of electrical power. The panel or tray may also be conveniently manipulated and can be easily removed from the housing and as a result work upon the same is rendered quite simple. It is also unnecessary as will be observed, to completely dismantle the signal from the support post to which it is attached, which is in most instances, quite a job. It will be noted that entrance to the housing is gained from the front rather than from the rear and access to the device is quite simple as compared to other devices. The use of the ring members 42 and 43 insures that the hood and the housing do not become separated and also provides for a loose connection so. that the respective flanges may be aligned and the bolts inserted through the holes to secure the hood and housing together.

FIGURES 7 through 13 show the modified form of the pedestrian control signal which includes in combination a housing 160 having a back wall 101, four side walls 102 through 105, respectively, and an open front face. A hood 108 is secured to the housing by way of screws 109, and the hood extends around three sides of the open front face. The hood serves to enable pedestrians to observe the signal 7 more easily. Wall means 111 serve to define a flange which is carried on the side walls and extends completely around the inner surface of the housing. As will be noted, the flange is spaced from, the open front face of the housing a predetermined distance.

A tray or panel member 114 is provided which has substantially the same shape as the open front face of the housing and is also provided with first and second side portions 116 and 117, respectively. Lamp means 119 are carried on the first side of the tray 116 and in this embodiment, the lamp means include first, second, and third continuous gaseous tubes 121, 122, and 123, respectively. The tubes 121 and 122 are preferably red in nature when illuminatedQand the gaseous tube 123 is preferably green in color. Electrical circuit components 125 arecarried on the second side 117 of the tray and serve to aid in illuminating the gaseous discharge tubes carried on the first side of the tray. These electrical circuit components are similar to those described in the signal of FIGURES lthrough 6. An enclosure member 127 is provided for housing the lamp means referred to above and the enclosure member comprises four side walls 129 through 132, which give the enclosure member substantially-the same shape as the open front face of the housing and a depth approximately the same as the above-referred to predetermined distance. Before assembly, the enclosure member has an open front and back. A wall member 134 serves to divide the enclosure member into first and second chambers 135 and 136, respectively. The open front of the first and second chambers 135 and 136 are closed by transparent or translucent glass members 139 and 140, respectively. The glass member 139 has black paint applied on the inner surface thereof in such manner as to spell out the word DONT; and in a like manner, the word WALK is spelled out on the second glass member 140. A sealing member 142 (FIGURES 10, 11, and 13) extends completely around each of the glass members 139 and 140 and lies between the glass members and a flange 144 on the enclosure member 127. The sealing member 142 is squeezed between the glass member and the flange 144 by means of a plurality of springs 146. The construction and operation of each one of the spring members 146 may be best understood by referring to FIGURE 13. Each of the springs 146 is constructed of flat spring material having a first end portion 148 lying in generally flat engagement with the glass member. A toe portion forms an integral part of the spring and overhangs a side of the glass member to prevent movement of the spring member in one lateral direction, indicated by the arrow 151. The direction of the force tending to squeeze the sealing member 142 between the glass memher and the flange 144 has been indicated by the arrow 152. The spring has a second end portion 154 which is secured to and extends from the first end portion 148. The extreme end of the second end portion 154 engages an abutment 155 for a purpose which will be described hereinafter. The straight line distance between the abutment 155 and the point of connection 156 between the first and second end portions of the spring is less than the length of the second end portion. As a result, in order to assemble the spring member into the full line position indicated in FIGURE 13, it is necessary to first place the spring in the dotted line position and move it into the full line position by pushing it in a direction opposite to the arrow 151. It may thus be said that the second end portion of the spring in the assembled condition is bowed in another lateral direction which is opposite to the lateral direction indicated by arrow 151. It will thus be seen that any force exerted on the glass members from outside the enclosure only tends to urge the spring members more strongly in said another lateral direction.

The back of the enclosure member 127 is closed by means of the tray or panel member 114 which is secured in place by means of screws 158. With the tray in place, as described, the gaseous discharge tube 121 resides in the first chamber 135 whereas gaseous discharge tubes 122 and 123 reside in the second chamber 136. Handles 159 and 160 are connected to the enclosure member and serve as a convenient means for placing the enclosure member with the attached tray into and out of the housing. The enclosure member is securely held in :position in the housing by means of bolts 161 which extend through U-shaped slot 162 in the end of a bar member 163 which is fixedly connected to the enclosure member.

In order to supply electrical energy to the electrical circuit components and the lamp means, a switch indicated generally by the reference numeral 166 has been provided. The switch includes a first switch part 168 fixedly mounted on the side wall 102 of the housing 100 a distance from the open front face which is greater than the above-referred to predetermined distance. The switch also includes a second switch part 170 which is fixedly secured by means of bolts 171 to the second side of the tray 114. The second switch part 170, therefore, moves with the tray or panel member.

It will thus be seen that when the enclosure member to which the panel member 114 is attached, is removed from the housing by using the handles 159, and 160,

6. the first and second switch parts 168 and 170, respectively, are separated. This disconnects the electrical circuit components and the lamp means from the external source of electrical energy which is supplied to the first switch part 168 in a manner similar to that shown in the device of FIGURES 1 through 8. FIGURE 12 shows the first and second switch parts in contacting engagement with each other when the enclosure member is in place in the housing and resting against or supported by the flange 111. It is with this construction that the new and novel means for housing the gaseous discharge tubes in the enclosure member is provided along with the convenient means of disrupting the supply of electrical energy when the panel member and enclosure member are removed from the housing. It will also be appreciated that the spring means provided for holding the translucent or transparent panels in position provides a very novel construction. It might also be pointed out that the arrangement of the electrical circuit components is such that tubes 121 and 122 are energized at the same time, thus illuminating the words, DONT WALK in red and tube 123 is energized by itself thus illuminating the word, WALK in green.

This application is a continuation-in-part of my appli cation, Serial No. 663,142, filed June 3, 1957, for Signal Construction.

Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
