SIGNAL DEVICE Filed Oct. 24, 1935 Patented Dec. 1936 UNITED STATES PATENT OFFICE SIGNAL DEVICE Oliver 0. Ritz-Weller, Chicago, 111.

Application October 24, 1935, Serial No. 46,548 'iClaims. (01. 40-125).

My invention relates to signal devices and it has for its object the provision of a new and improved form and arrangement of parts in a device of this type whereby it is made highly effective for use as a protective marker on a highway or the like at opposite sides of an obstruction by which the way is partially or wholly blocked.

It is one of my objects to provide an improved form of signal device which shall be effective either by day or by night forgiving a warning of a truck parked or broken down on a pavement. It is another object of my invention to provide an improved device of this type arranged so that it can be folded into very compact form for transportation and can then be very quickly and easily spread out into effective form so as to have a flnn and stable stand on a flat pavement and so as to resist successfully any probable tendency for the device to be upset or otherwise thrown out of operative condition by the wind or other weather conditions. It is one of the objects of my invention to provide an improved device which may be easily and quickly available for use in this manner and which may be as nearly as possible completely proof against failure. It is another object of my invention to provide a device of this type which may be conspicuous by day and which by reason of a reflector mounted on its face may be illuminated brightly at night by the forwardly projected rays from the headlights of an approaching automobile.

It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the accompanying drawing and are hereinafter specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims.

In the drawing-- Fig. 1 is a perspective view of the preferred form of my improved signal device;

Fig. 2 is a vertical sectional view through the device of Fig. 1 when folded together into compact form for transportation;

Fig. 3 is a horizontal sectional view taken at line 33 of Fig. 1;

Fig. 4 is a fragmentary view of a portion of the rear face of my improved device;

Fig. 5 is a front face view of the lower righthand corner of the device as shown in Fig. 1, one of the supporting arms being shown in changed position as compared with the showing of said Fig. 1;

Fig. 6 is a fragmentary view of the lower righthand corner of the device as seen from the right.

side of the deviceillustrated in Fig. l; and- Fig. '7 is a vertical sectional view taken at line Y Q 1-1 of Fig. 4.

Referring now to the several figures of the drawing, in which corresponding parts are indicated by the same reference characters, III, II

and I2 indicate three panel sections of sheet metal connected together along their side edges by means of hinges l3, the pivot pins of which are offset forwardly, as is best shown in Fig. 3, the arrangement being such that when the twoend sections Ill and i2 are folded over upon the front face of the intermediate panel section I I the face portions of the end panels'are in substantially spaced relation to the face of the intermediate panel section I l. Upon the rear face of the panel comprising said sections III, II, and I2, I have pivotally mounted locking arms I! and I5 whichare movable into engagement with a clip I6 carried by the intermediate section II so as to hold the sections releasably in face alignment with each other as is shown in Fig. 3.

As is best shown in Fig. 3, the outer edge por- 'tions of the end panels I0 and I! are bent forwardly in the form of flanges l1 and larespectively which serve very substantially to strengthen and stiffen the panel as a whole. Upon the lowerends of the flanges H and i8, I have pivot-p ally mounted supporting arms 19. 20, 2|, and 22, two of such'arms'being mounted-upon opposite faces of each of said flanges i1 and I8 by means of pivot pins 23 which in the arrangement shown are fastened tightly enough to hold the supporting arms by friction in any position to which they are swung with respect to the. flange. For locking the supporting arms in their extended position as shown in Fig. I, I have provided spring latch devices 24 which areadapted to be forced inwardly for allowing the arms to be folded into position along 'the' flange and which inhtheir normal position engage the top faces of the arms as shown in'Fig. 5 for locking-the-arms against swinging movement. For providing the desired clearance for the arms with respect to the latch devices, I have employed washers- 25;

on the pivot'pins 23between the'supporting arms a and the flanges i1 and I B.

On the front face of the lntermedi'atepanel section II, I have provided a reflector 26 of any approved type adapted to be illuminated by the rays from the headlights of an approaching auto-' mobile so as. to; indicate clearly the presence of the front face of the intermediate section II so as not to interfere with the folding of the sections together into compact form for transportation, the reflector being enclosed withinthe housing provided by the sections when the sections are folded together.

When it is desired to transport the device, the supporting arms I9, 20, 2|, and 22 are, of-course, folded upwardly along the sides of the flanges i1 and I 8 and the sections In and 12 are folded over upon the intermediate section II. In this condition, as will be readily understood, two of the signal devices take up very little room in a truck, and the reflector member 26 of each of the devices is amply protected against breakage. When the signal devices are required at opposite sides of the truck so as to give a warning as to the presence of the truck, the devices can be very quickly and very easily spread out into their. completely extended form as shown in Fig. 1, the parts being easily and quickly locked in such extended form as above described. With the device in position upon a pavement with the supporting arms spread as shown in Fig. 1, the device as a whole has very strong and stable support in its upright position on edge so as to hold the reflector 26 in conspicuous position. The arrangement is such that the device cannot be blown over by any ordinary wind pressure and the device is not affected in any way by rain. The nature of the device is such that it is ready at all times for instant effective use even though it has not been used or inspected for months or even years. There is nothing about the device which has any tendency to deteriorate, the device being as nearly as possible proof against failure under any probable conditions. In the preferred form of device, the words Truck stalled are shown on the front face of the panel so as to be more effective as a signal by day. The device is preferably painted or enameled in bright colors so as to be as conspicuous as possible.

While I prefer to employ the form of device as shown in the drawing and as above described, it is to be understood that my invention is not limited to the form shown, it being understood that changes might well be made in the form and arrangement of the parts without departing from my invention.
