ROADSIDE SIGNAL.

Application filed October 10, 1925. Serial No. 61,692.

This invention is a roadside signal device of the type used to impart warnings as to trafiic or to indicate road conditions.

One of the objects of the invention is to provide a signal device of the character mentioned which will be simple in construction, but capable of withstanding to a maximum degree, deterioration under exposure to the action of the elements and such attempts at destruction as may be due to vandalism. A further object is to provide a signal device equipped with a normally unbreakable light reflecting surface, means for coloring a beam of light reflected therefrom, and means for affording maximum protection for said sur, face. A further object is to provide simple means for focusing the device.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a front elevation illustrating a signal device constructed in accordance with the invention. Figure 2 is a side elevation thereof.- Figure 3 is a transverse sectional view on the line 3-3, Figure 2. Figure 4 is a detail sectional view illustrating means for changing the focus of the reflector. Figure 5 is a perspective view illustrating one of the supporting devices. Figure 6 is a detail view illustrating a modification of the'protector frame.

Referring'to the drawing, 10'designates a back plate of any desired size and shape,

' to which is secured a protector frame 11.

The frame 11 is preferably constructed with a base flange-12 and an overhangingtopflange l3, bolts 14 being shown,aspassed 'through ,the base flange and the back plate to secure the frame in place. I

The light reflecting element comprises a metal sheet 15, having one surface polished colored material.

to provide a reflector, said polished surface. being'covered-by a sheet 16 of transparent The sheets 15 and .16 are bound together at their edges by suitable binding strips 17, as shown, so that the back surface of said color screen will be in contact throughout its area with a correspondingarea of the front surface of the reflector member. Any desired contour may be imparted to the surface of sheet 15, but for purposes of illustration it is shown slightly concaved.

For the purpose .of the invention it is preferred to construct sheet 16 of a material which will not easily fracture under shocks, such as some of the forms of cellulose materials now on the market. The light-reflecting element is held in place by the lower flanges 18 of anchoring devices 19, which are removably secured to the body of frame- 11, by means of bolts 20.

Interposed between the top flange 13 of the frame 11, and the contiguous top flanges 21 of the anchor members, and retained in place by them, is a wire mesh protector screen 22. Said screen is of sufficiently heavy mesh to resist the blows of large stones and other missiles which may be projected against it, and is also spaced far enough from the reflector member to protect the latter from injury or defacement by vandals.

It is sometlmes desirable to change the angle of a portion of the reflector member with respect to the back plate 10. Such adjustment may be accomplished by means of the arrangement shown in Figure 4:. Re-. ferring to said figure, 23, designates an adjusting screw, mounted in the back plate 10, and bearing against the underside of the sheet 15 near the edge thereof. It is ob- .vious from the drawing that the angle is variedby adjusting the screw 23, the reflector member being sufficient-l resilient to yield when pressure is, app ied thereto.-

When the adjusting device of Figure 4: is used, the anchor devices 19 are made in twoparts as shown, so that the position of the lower flange may be changed to conform to the adjustment of said reflector members.

.The signal .device may be supported in any desired manner. It is preferred, however, to provide the back plate 10 with lugs '24, each provided with a slot'25. Complemental to said lugs are support straps having loop. portions 26 shaped toembrace a post 27, and having arms 28 NVhlCl'l overlap ,tary structure.

the lugs. The loop portions 26 are tightened or loosened by means ofbolts 29, and the arms 28 are. connected to the lugs 24: by means of bolts 30 which pass through the slots 25. If desired suitable signs 31 may be attached to the device as shown pass around the-post, after which the loops are tightened to' clamp the said post. The arms 28 are then connected with the lugs 24 by means of the bolts 30. To focus the sign, any desired radial-position with respect to the post, is obtained by loosening the loops 26 and then turning the support straps to the desired angle, after which the loops are again tightened. The vertical angle may be varied by loosening the bolts 30 and tilting the, signal member, the slots 25 and the arms 28 serving to permit this adjustment.

If any finer adjustment of fpcus is required it may beefl'ected by means of the screw 23.

In lieu of making the protector frame of a single piece of metal as shown in Figures 1, 2 and- 3, it may be desirable to make it of from an automobile headlight, will be reaplurality of parts as illustrated in Figure 6, in which the parts of the frame are shown as provided with a joint 30. In this form of the invention the anchor members 31 perform the additional function of reenfor'cing or splicing said joint.

The advantages'of the invention will be readily apparent to those skilled in the art to which it belongs. For instance, it will be noted that by constructing the reflector of metal it may not be broken, and therefore will withstand shocks which would be fatal to glass. Neither will it readily deteriorate under the action of the elements. By employing a transparent color screen, the refleeting qualities of the metal sheet 15 are not in the leastimpai-red, and it is possible to impart any desired color which may be considered suitablefor signal purposes. An important advantage of this arrangement is that at night, the beam of light projected flected back in such a; manner as to give the effect of a colored beam of light projected toward the'driver, and thus promptly warn him of the position of the signal. The

means by which the device may be focused insures a maximum of efficiency inthe performance of this reflecting function. By

.adding the heavy protective wire screen, the

reflector may not be readily damaged and is not readily open to injury by vandals or missiles. It will be. particularly noted that the signal is very simple in construction, can be manufactured at small cost, and is of a character which may be equally useful in congested areas as well as in the less settled districts.
