TRAFFIC SIGNAL LIGHT William E. Jones, Tulia, Tex. Application September 16, 1943, Serial No. 502,681
1 Claim.
. sure the proper signalling of the approach of an auto-mobile on the intersecting road, regardless of the position of the automobile. A further object of the invention is to provide a light of this character which can be readily adjusted to accurately reflect the light on the boulevard regardless of the angle of the intersecting road.
A still further object of the invention is to provide a simple and efiective light of this char acter, in which the parts can be readily replaced and, at the same time, can be cheaply manufactured and assembled.
In the accompanying drawing: Figure 1 is a side elevation of my improved Figure 2 is a horizontal transverse sectional view, taken on the line 2-2 of Figure 1;
' Figure 3 is a diagonal sectional view, taken on the line 3-3 of Figure 2, with the lower end of the housing broken away.
Referring now to the drawing, I represents a vertically disposed elongated housing divided intermediate its upper and lower ends by a horizontal partition 2. The housing is square in transverse section and arranged within the housing, above and below the partition 2, are two reflecting lights constructed exactly alike but arranged in reverse position so that one light reflects in one direction and the other light in the opposite direction. In describing the construction, the upper light will be used to illustrate the invention.
The wall 3 of the housing, facing the road intersecting a boulevard, is provided with a glass panel 4, having a visor 5 surrounding the upper end and side walls thereof. The wall 6, arranged at right angles to the wall 3, and adjoining the same, is provided with a lens partially surrounding the same. Carried by the partition 2, in the corner 9 of the housing, is a stud l0, upon which is pivotally mounted an arm II, which extends towards the opposite corner between the glass panel 4 and the lens I. This arm is providedwith an elongated slot I2, through which extends a vertical rod I3, having a lock nut l4 below the arm, and a lock nut I5 above the arm, whereby the rod is held in its 1, having a visor 8,
adjusted position in the slot. The upper end of the rod I3 is provided with a ball I6, entering openings in the laterally extending ears I! and I8, carried by the reflector support I9. These ears are locked in their adjusted position on the ball by means of the bolt 20. The reflector support I9, as shown in Figures 2 and 3 of the drawing, carries a convex reflector 2I, extending at an angle of approximately forty-five degrees to the lens and the glass panel. While I have shown this reflector of convex form, it will be understood that it could be straight, concave, or of any desired form to meet the conditions under which the light is to be used.
Carried by the partition 2, adjacent the glass panel and the lens, is a segmental plate 22, spaced from the partition and having an alongated se mental slot 23 therein. The arm II passes under the segmental 'plate 22, and a thumb nut 24 passes through the slot 23 into the arm I I, whereby the arm is held in its adjusted position on the plate 22. By this arrangement, it will be seen that the reflector 2I can be adjusted in respect to the glass panel and lens to meet the conditions under which it is to be used.
The light arranged in the lower half of the housing I has the lens 25 in the wall 3 and the glass panel 26 in the wall 6, whereby the light is reflected in the opposite direction to that of the light in the upper part of the housing. By this arrangement, it will be seen that the light is reflected in opposite directions.
The light from an approaching car on a road intersecting the boulevard passes through the glass panel 1, as indicated by the arrow, Figure 2, striking the mirror or reflector 2|, and passes out through the lens 4. The reflector, by means of the thumb nut 24, nuts I4 and I5, and the ball connection I6, can be accurately adjusted, so as to cause a perfect reflection of the light through the lens to meet all conditions under which it is used.
What is claimed is:
A traffic light of the character described, comprising a rectangular housing, a glass panel in one wall of the housing, a lens in the adjoining right angle wall of the housing, an arm pivoted at one end within the rear end of the housing and extending at an angle of forty five degrees to the panel and lens and having a vertical slot therein, a standard adjustably supported within the slot of the arm, a reflector arranged transversely of the arm and having a universal connection with the upper end of the standard, and
a slotted segment secured to the housing opposite the pivot point of said arm for supporting the free end of the arm and having means for ad- .iustably securing the arm within the slot.
WILLIAM E. JONES.
