Description
Aug. 23- 1938. J. ROSENER ROAD REFLECTOR Filed July 3, 1957 Patented Aug 23, 1938 UNITED STATES PATENT. OFFICE 1 ROAD REFLECTOR Ilarold J. Rosener, New Ulm, Minn. Application July 3, 1937, Serial-No. 151,932
1 Claim. (Cl. 40- --125) This-invention relatesv generally to reflectors, and more especially to a double lighting center line road reflector.
One object of my invention is to provide a road 5 reflector that may be embedded in the concrete highway with only the upper semi-sphericalorv half-ball like head of the piston or plunger that carries the'refiectors, exposed.
piston or plunger is mounted for vertical reciprocating movement in a suitable casing or housing and is instantly depressed when brought into contact with a snow plow or similar device, 15 in order to prevent damage to either thereflector or the snow plow. Another object of my invention is to provide a road reflector of the character specified, which is simple and economical in construction and 20 highly eflicient and durable in uses, 7
With the foregoing and other objects in .view that will appear as the nature of my invention is better understood, the same consists in the novel features of construction, combination and 5 arrangement of parts illustrated in the accompanying drawing, and more particularly pointed out in the appended claim. 7
In the accompanying drawing, in which like parts are designated by like reference characters 30 throughout the several views, and which are for illustrative purposes only and are therefore not drawn to scale; v
Figure 1 is a side elevation, illustrating the application of my invention.
'35 Figure 2 is a vertical transverse section.
The casing l is of hollow cylindrical form and 50 is preferably constructed of aluminum or other light durable metal. It is made with a corrugated or roughened outer surface 5, to prevent the same from working loose in the concrete street or highway in which it is embedded.
5 The piston 3 comprises the hollow cylindrical body portion 5, and the solid semi-spherical or half-ball like head I, whichcarries the two ppositely disposed counter-sunk light reflectors 8, of any ordinary or approved construction. The semi-spherical head I of the piston, together with the reflectors 8, are the only parts of the complete device that are normally exposed above the upper surface of the highway, and the upward movement of the piston is governed or limited by the flange 9 of the interiorly threaded 10 annular ring 9' which screws on the interiorly threaded upper end [0 of the casing.
In carrying out my invention, the hollow cylindrical body portion 6 of the piston 3, is formed with an outwardly extending lug II, which works in a corresponding recess or key-way l2 formed in the inner wall or surface of the casing I. The coil spring 4 is mounted in position with its upper end l3 extending into the hollow body portion 6 of the piston 3 and bearing against the bottom wall Id of the semi-spherical head I, and with its lower end fitting around the annular boss or flange 15, formed at the lower open end of the casing.
With the type of road reflector now in use, the blade of the snow plow not only often catches the reflector and tears the same out of the street or highway, but the plow blade itself is often seriously damaged or wrecked. It is. claimed, however, that this objection can beentirely overcome through the adoption and use of my new design, by virtue of the fact that the semi-spherical o r half-ball like head of. the piston carrying the light reflectors, will be instantly depressed to or slightly below the upper surface or level of the highway when brought into contact with the plow blade and permit the latter to freely pass thereover. It'will be understood that when the pressure on the head of the reflector is released, the piston 3 will be imme- 40 diately returned to its normal elevated position by the action of the-coil spring 4.
From the foregoing description taken in connection with the drawing, it is thought that the construction, operation and advantages of my invention will be readily understood, without requiring a more extended explanation.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is:
In a road reflector of the character specified, 5 a. cylindrical casing or housing formed inits inner surface with a vertical key-way, a hollow cylindrical piston mounted for vertical reciprocating movement in the casing, said piston formed with an upper semi-spherical or ball-like head normsiiy exposed above the upper edge of the casing snd provided on its outer surface with an outwsrdly projecting pin or stud working in said key-wsy, light reflectors carried by said semispherical head, a coil spring for norms-11y supporting the piston in raised operative position. said spring arranged with its upper end closely fitting within the hollow body portion o! the piston snd its lower end bearing on the bottom of the casing or, housing, and an interiorly threaded collar screwed on the upper end of the casing end formed with an inwardly extending beveled flange limiting the upward movement of the 5 piston.
