Claims.

This invention relates to supports or stands primarily intended for emergencyusev in supporting signal lights or flares on the roadway of cement and similar hard surface highways, 5 though capable of otheruses.

Various- States now require auto, busses and truckspassing over their highways todisplay on the highway in. such position as to clearly light up; the side, of the buss or truck closest to the center of the signal flares or lights and to so place these onthe roadway as to indicate the degree of obstruction: of the highway by such buss or truck in; case of any accident or failure to function of; thebussor truck which involves the light circuits or system to such degree as to render the ordinary lights of'the buss or truck inoperative; Inmost such- Statesthe regulations require such busses or trucks to carry not less than a specified: minimum number of approved signal lights onflares so: formed, orprovided with such accessories that the same may be quickly placed and supported in position on any kind of roadway. A downwardly depending spike depending from the flare body is a usual construction for fixing such flares in an upright position in a macadam and similar roadbed, but utterly fails to meet the need on a cement or similar roadbed.

The present invention has been developed with the above considerations particularly in view and has as its primary objects to provide a stand or support which maybe collapsed into small space for storing and transit and which as spread will be reliable and certain in operation; to provide a stand or support which will be locked against spreading beyond a definite angle or degree; to provide a stand or support so receiving and supporting the signal light or flare as to distribute the weight of the flare equally or substantially equally on opposite sides of the body of the flare or signal light to avoid overturning of the stand or support; to so relate the angle of the supporting socket to the supporting base as to hold the body of the signal light or flare at an angle inclined in the direction of said base whereby the weight of said body of the flare or signal light will actto press the said base against the road- 1 way; to provide a very efficient supporting stand capable of very economical production.

' In the accompanying drawing:

Figure 1 represents a perspective View of a device embodying our invention in use supporting a flare or signal light such as above referred to;

Figure 2, a fragmentary detail exploded View of the two members of'the support or stand;

Figure 3, a sectional view on the line 3-3 of Figure 5; looking in the direction of the arrows, the lower portion of the body ofa flare being illustrated in side elevation in position as held by a the stand orsupport;

Figure 4, a fragmentary side elevation of the 1 interengaging or interlocking portions of the two members of the support or stand; and

Figure 5, a top plan view of the fragmentary portions shown in Figure 4.

Referring now in detail to the drawing l' and: 2 respectively designate relatively long preferably straight relatively stiff wire form metal rods having their adjacent end portions bent upward at an angle of approximately 20 degrees as at 5 and fi respectively, and. having their extreme rear portions wound in the form of helices 3 and 4 respectively, the relative; sizes of such helices 3 and 4 being such that the helix 4 will make a screw-thread engagement between the coils of, and may beiscrewed into, the helix, 3.

The inclined portion 6 of rod 2 will be bent laterally intermediate the ends of said portion 6 to such degree that when the portion 13 engages the opposed face of portion 5, which occurs when the helix 4 has been screwed into helix 3 to its extreme limit, all as illustrated in Figure 4, the straight portions of the rods land 2 will extend at an angle of approximately 50 degrees with relation to each other and the common center of the helices 3 and 4 will be intersected by a line bisecting said angle.

The axes of the helices 3 and 4 will preferably be substantially perpendicular to the portions 5 and 6 respectively so as to be inclined upwardly and forwardly toward the rods l and 2 at an angle of approximately 20 degrees and the spike B of the flare body A will tilt at an angle of between 5 and 10 degrees in the helix 4, asillustrated in Figure 3, so that the body of the flare or signal light A will extend upwardly and be inclined forwardly at an angle of approximately 25 to 30 degrees to the vertical with relation to the roadbed 0 and centrally, or approximately centrally, between the rods l and 2.

The inclined-portions 5 and 6 will preferably be of such length that with the bottom of the flare body A resting on the top of the helix 4 the lower end of the spike B will be held at a slight distance from the roadbed C and preferably the length of the support or stand as collapsed will not be less than the approximate length of the body of the flare or signal light A.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A collapsible stand comprising a pair of wire rod members, each member having a long preterably straight horizontal portion extending from its free end rearwardly for most of the length of said member, an inclined portion extending rearwardly and upwardly from said straight portion at an angle of approximately twenty degrees and having its extreme rear end portion formed into a helix, the helices of said members being of such relative sizes that the helix of the one member will make a snug screw fit in the helix of the other member, and the upwardly inclined portion of one member engaging against the opposing face of the inclined portion of the other member when said helices have been screwed tightly together and being laterally bent to such extent that with said helices in such relationship the straight portions of said members will extend at an angle of approximately fifty degrees with relation to each other and a line bisecting said angle will intersect the common axis of said helices, said axis extending approximately perpendicular to said inclined portions.

2, A collapsible stand comprising a pair of wire rod members, each member having a long preterably straight horizontal portion extending from its free end rearwardly for most of the length of said member, an inclined portion extending rearwardly and upwardly from said horizontal portion at an angle and having its extreme rear end portionformed into a helix, the helices of said members being of such relative sizes that the helix of the one member will make a snug screw fit in the helix of the other member, and the upwardly inclined portion of one member engaging against the opposing face of the inclined portion of the other member when said helices have been screwed tightly together, said members extending at an angle to each other when said helices are so related, and a line bisecting the said angle intersecting the common axis of said helices, said axis extending approximately perpendicular to said inclined portions.

3. A collapsible stand comprising a pair of wire rod members, each member having a relatively long substantially horizontal portion and having its rear end portion formed into a helix, the helices of such members being of such relative sizes that the helix of the one member will make a snug screw fit in the helix of the other member, said members definitely engaging with each other and preventing further relative rotary movement when said helices have been screwed together to their extreme position and at such time extending at an angle to each other substantially in the same horizontal plane, and the common axis of said helices extending upwardly and being inclined forwardly toward and between said horizontal portions.

4. A collapsible stand comprising a pair of wire rod members, each member having a relatively long substantially horizontal portion and having its rear end portion formed into a helix, the helices of said members being of such relative sizes that the helix of the one member will make a snug screw fit in the helix of the other member, and the common axis of the helices in assembled relation extending upwardly and being inclined forwardly toward and between said horizontal portions of said members.

5. A collapsible stand comprising a pair of wire rod members, each member having a relatively long substantially horizontal portion and having its extreme rear end portion formed into a helix, the helices of such members being of such relative sizes that the helix of the one member will make a snug screw fit in the helix of the other member.
