HIGBWAY SIGN Filed March 2, 1955 Clafence A. Garmac/r INVENTOR.

United States Patent HIGHWAY SIGN Ciarence A. Carmack, Pocatelio, Idaho Application March 2, 1955, Serial No. 491,714 3 Claims. (Cl. 40125) The present invention relates to new and useful improvements in highway signs to warn drivers of motor vehicles of the approach to dangerous curves.

An important object of the invention is to construct a sign supported on a sign post and shaped with a tapering curved tip to indicate to the motorist a correspond-. ing curve in the highway.

Another object is to provide the sign with a panel at the lower portion of the sign upon which a safe speed may be painted for traveling on the indicated curve of the highway.

A further object is to include in a highway sign system a group of signs of dual construction and each having both right and left outwardly curved tapered tips as a warning of the approach to both right and left curves in a highway, one immediately following the other, and constructing the two tips of different lengths whereby the shorter tip may be used to indicate the direction of the first curve in the highway and the longer tip used to indicate the direction of the second curve.

A still further object is to include other novel features of construction in the sign which are important to the safety of highway travel and embodied in an article of manufacture of simple and practical construction yet attractive in appearance and which may be manufactured at relatively low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a front elevational view of a sign indicating an approaching left curve in a highway;

Figure 2 is a similar view of the right curve sign;

Figure 3 is a front elevational view on an enlarged scale of a dual sign indicating both a right and left curve with the right curve of greater length; and

Figure 4 is a similar view of another dual sign wherein the left curve is of greater length.

Referring now to the drawing in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of my invention, the highway sign designated by the numeral 5 in Figure 1 is constructed of sheet metal or other suitable material and includes a lower panel portion 6 of predetermined size and an upper tip 7 of a width corresponding to the width of the panel and tapering at its upper end and curved toward the left.

The sign is attached in an upstanding position to a post 8 placed adjacent a highway 9 at the approach to a curve toward the left (not shown) whereby the curvature of the tip 7 will warn motorists that they are approaching a dangerous curve.

The front surface of tip 7 is painted with luminous paint or otherwise treated to provide a light reflecting surface for readily seeing the sign at night. The front of panel 6 is painted or has displayed thereon a legend 10 indicating a maximum safe speed at which the curve should be traveled and may also be painted with luminous paint or provided with light reflecting means.

Figure 2 illustrates a sign 11 which includes a lower panel 12 and upwardly tapering tip 13 curved toward the right to indicate a right curve in a highway. The sign 11 otherwise is constructed similar to the left curve sign 5.

Figures 3 and 4 illustrate dual signs 14 and 15, respectively, and each of which includes a lower panel member 16 and a pair of upwardly tapering tips 17 and 18 which are curved outwardly in opposite directions to indicate an approach to both left and right curves. Tip 17 of Figure 3 is relatively short and curved toward the left to indicate the first curve is in that direction, while tip 18 is substantially longer and curved toward the right to indicate a corresponding direction of the second curve.

The duel sign illustrated in Figure 4 is constructed with the relatively short tip 19 curved toward the right to indicate the approach to a first curve in the highway in that direction and with a substantially longer tip 20 curved toward the left to indicate a second curve in the highway in the last named direction.

Otherwise, the dual signs 14 and 15 are constructed similar to signs 5 and 11.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous skilled in the art, it is not desired to limit the invention .to the exact construction and operation described and shown, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A highway warning sign comprising a rigid elongated body of sheet material, means supporting the body in an edgewise upstanding position, said body including a panel at its lower portion adapted to display a warning indicia thereon, and a coplanar tip integrally formed and displayed in silhouette at the upper portion of the body curved outwardly at one side edge thereof and having a tapered upper end.

2. A highway warning sign comprising a rigid elongated body of sheet material, means supporting the body in an edgewise upstanding position, said body includ ing a panel at its lower portion adapted to display a warning indicia thereon, and a pair of tapered integrally formed tips extending upwardly from the panel portion and curved outwardly at the opposite side edges of said body in silhoutte display.

3. The construction of claim 2 wherein one of said tips is shorter than the other.
