STREET TRAFFIC SIGNAL Filed March 17, 1950 7 INVENTOR 770% E. f/ojfscfirm'af ATTOR Patented Sept 27, l -932 UNITED STATES PATENTOFFICE ROBERT E. HUFI'SGHIIDT, OF PORTLAND, O BEGON, ASSIGNOR TO K. E. ERICKSON, O

PORTLAND, OREGON srannr mm SIGNAL My invention is intended for use for placement at street intersections, street crossings, reverse curves on highways, and in any and all places where it is intended to indicate to 5 approaching night traflic,'the location of the traific' signal. The location of the trafiic signal is indicated through reflected light rays from the head lights of the approaching vehicle. i The invention consists primarily of a body element, a reflector 'adjustably mounted, in the body element and a .lens hermetically sealed and removably placed within the body element. Means are provided for the fasten- 5 ing of the body element to the roadway and the body element is so made as to present a amount of resistance to motor vehicle tires-passing thereover.

' Heretofore, devices of this kind have been so arranged that the lens was easily broken by pneumatic or solid rubber tires passing thereover. The breakage was primarily caused by the close proximity of the lens to the front wall of the body element.

In'my new and improved device, the lens is placed sufliciently rearwardly of the front wall to prevent the surface of the tlre from being compressed into contact with the lens itself. One of the primary objects of my invention is to provide a reflecting surface that is adjustably positioned within the body element so that the light rays may be reflected upon the lens to illuminate the same irrespective of the grade of the roadway upon which the body element is to be placed.

A further object of my invention conslsts in providing an indicator light having a lens removably disposed therein in order that the reflector may be adjusted, altered or recon- 40 ditioned without the destroying of any portion of the device itself.

A further object of my invention resides in a construction of minimum first cost and of relatively long life that will ofier a minimum of resistance to vehicle tires passing thereover. I.

A further object of my invention consists in providing a device of a one-piece body element having areflecting surface adjustably positioned and hermetically sealed therein -more in' detail, the position and adjusting and having one or more lenses disposed rear- 'wardly of the front sloping wall of the body element. The lenses are removably secured within the body element. 1

With these and incidental. objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawing which accompanies and forms a part of this specification.

In the-drawing:

Fig. 1 is a front view of the assembled device having two lenses removably disposed within the body element rearwardly of the front wall of the same.

Fig. 2 is a top, plan view of the mechanism illustrated in Fig. 1.

Fig. '3 is a side view of the mechanism illustrated in Figs. 1 and-2.

Fig. 4 is a sectional, side view of the assembled device, the same being taken on line 44. of Fig. 1 looking in the direction indicated. q A

Fig. 5 is a fragmentary, sectional, side view of the assembled device, the same being made on a somewhat larger scale to illustrate,

features for the reflector, the lens in position, the means forsealingthe same therein and the means for. maintaining the lens and the reflector fixedly positioned within the bod element. I

ig. 6 is a fragmentary, partially sectioni l, front view of the mechanism illustrated in Fig. 7 is a fragmentary, sectional, side View of the lens and the fastening means therefor,the same being taken on line 7 -7 of Fig. 6 looking in the direction indicated.

Fig. 8 is a front view of an assembled device of a single lens disposed centrally of the front wall of the body element.

Like reference characters refer to like parts throughout the several views. 7 I preferably form my device of a one-piece body element 1. The body element has a rearwardly sloping front wall 2-, sloping side 100 walls 3 and 4 and a sloping rear wall The body element has a substantially flat base 6 for resting upon the street or roadway surface. Each of the sloping walls of the body element should be suflicient to offer a minimum resistance to the vehicletires that are at times forced thereover. A recess 7 is formed within the front wall and one or more seats are disposed within the recess for the retention of the lenses therein. The seat for the lens to be placed within the body ele- I 9 therein. I preferably form this reflecting surface of a highly polished non-corrosive metal and adjustably position the samewithin the barrel by an adjusting screw 10 that is in threaded relationship with the rear wall 11 of the barrel and of the body element. spring 12 is disposed about the screw 10 to normally maintain the reflector 9 in precise position relative to the lens and to the head of the adjusting screw 10. A seat 13 is disposed. at the forward end of the barrel 8 and outwardly extends therefrom for a suflicient distance to support a packing seal 14 there- 1 upon and a lens 15 is disposed upon the packing seal 14. The packing seal 14 is preferably made of plastic material, as litharge or any other suitable gasket cement or other substance or compound, that may be placed within the seat of the body element and upon which the lens is seated and which will harden thereafter, thus hermetically sealing the reflector 9 within the barrel 8. A recess 16 is formed wihin the body element for a portion of the circumference and preferably at the top thereof, as illustrated at 17 in Fig. 6'and in Fig. 1. A sealing ring segment 18Ais'made to engage upon the outer-rim 19 of the lens and to engage the inner surface 18 of the projecting ledge with the ends 20 and 21 of the ring spaced apart. The ring segment is made tapering or wedge shape on its outer surface in order that the same may be madeto forcibly engage the lens when driven or wedged within and between the projecting ledge 17 and the rim 19 of the lens.

After the ring segment has been driven home,

- the lower portion of the ring segment may then be forced into place and in intimate contact with the rim 19 of the lens by any suitable" fastening means as by a screw 22 that is .threaded into the base of the body element. The head of the screw contacts with the sloping surface 23 of the ring segment thereby maintaining the same in intimate engagement with the rim of the lens. Fastening holes 24 are disposed through the base of the body element through which any suitable fastening means as bolts or studs may be made to pass and to extend therethrough into the surface of the roadway for fixedly positioning the device in place and position.

While the form. of mechanism. herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of "embodiment in various forms, all coming within the scope of the claims which follow.
