Definitions

  • FIG. I PORTABLE TRAFFIC SIGNAL ,HAVING CHANGING-COLOR ILLUMINATION Filed April 19, 1963 FIG. I.
  • Permanently arranged signal lights suspended from posts or secured by other means, which change the signal colors either between green and red or between green and red together with an intermediate signal in yellow color, are well known, which devices are mounted on street crossings or on road crossings, in order to control the traffic on such highly frequented crossings. It is also known, to post traflic oflicers at such crossings, which traffic oflicers are equipped with a white stick for directing the trafiic manually for vehicles and pedestrians.
  • Such white stick has been found sufiicient during daylight hours, yet it has been found that during the evening and night hours, that means, if day light is not available, the white sticks were not sufiiciently visible for oncoming cars or pedestrians and accidents were unavoidable, which occurred on such crossings.
  • FIGURE 1 is an axial section of the device designed in accordance with the present invention.
  • FIG. 2 is a section along the lines 22 of FIG. 1.
  • the device comprises a cylindrical hollow gripping member 1, which has a plurality of annular extensions 2 axially spaced apart from each other and serving as gripping means for the user of the device.
  • the rear end of the cylindrical hollow gripping member 1 of wood, plastic or the like, is equipped with an inner thread 3, which receives threadedly a cover member 4 having outer. thread 5, and has .a diameter greater than that of the center portion of the gripping member 1.
  • the front end portion of the gripping member 1 has also a diameter greater than that of the center portion of the gripping member 1 and is likewise equipped with an inner thread 8.
  • a longitudinal bulb 9 of glass, plastic or anyother suitable material is frosted in a white color and has at its rear end an outer thread 10 which is received in the inner thread 8 of the gripping member 1,
  • the device serves the same purpose as a white stick usually carried by a traflic oflicer while on duty, without giving the appearance that it is simultaneously at night a stick which can be illuminated in a green, yellow or red color or merely in a green or red color.
  • One or a plurality of batteries 13 are received within the gripping member 1 and are retained in position rearwardly by the cover 4, while the front end of the batteries 13 abuts .against a cross wall 11, in which electrical wiring 12 is embedded, which forms terminals for engagement with the plus and minus terminals of the batteries 13 in-- serted in the gripping member 1.
  • An electric-commutator 14 is disposed in the gripping member 1 adjacent the opposite face of the cross wall 11 and is rendered operative by operation of a special switch 15.
  • the commutator 14 is of conventional structure and shown schematically only, the switch 15 being adapted to connect the commutator 14 with the batteries 13, so that current is fed automatically and successively to differently colored electric bulbs, as set forth below.
  • a switch-receiving member 15 shown schematically, which is equipped, preferably, with three sockets 16 receiving three electric bulbs 17 secured to the sockets 16 by screwing or in any appropriate manner, as it is well known for such electric bulbs 17.
  • a three-way switch 18 is operated manually by means of a knob 19 from which a shaft 20 extends through a bore in the wall of the gripping member 1 towards the switch 18.
  • the knob 19 it is, thus, possible to operate by means of the knob 19 the three bulbs 17, which are, preferably, of green, yellow and red color, either manually or, as stated above, by means of the commutator 14, which rotates continuously in its operative position and switches after a predetermined time period the current successively to the respective bulbs 17, thereby, changing the color appearing through the bulb 9 from green into yellow or into red.
  • circuit either through the commutator 14 or through the manual switch 18 can be brought about by any suitable means well known to the expert in the field.
  • a movable device for light signals comprising a hollow substantially cylindrical gripping member having a first inner thread at one of its ends and second inner thread at the other of its ends.
  • a longitudinal, white-frosted bulb having outer thread at one end and closed at its opposite end, said outer thread being received by said second inner thread of said gripping member, and said longitudinal bulb being adapted to be used as a traflic stick during dayi G light and as a trafi'ic light operating alternately different color bulbs, respectively,
  • said gripping member having at its center portion a plurality of annular extensions axially spaced apart from each other to permit easy gripping of said gripping member
  • circuit means controlled by additional manual switch means for connecting said commutator motor with said battery, whereby said bulbs may be operated in automatic succession by said commutator or selectively by said plural position manual switch.
