Referring more detail to the drawings:

1 designates a signaling de embodying the features of my invention co i's'ing signal elements 2 and 3 consisting of plates 4 and 5' preferably formed of colored glass or similar semitransp'arent material having lustere'd backing 6 thereon. The edges of the Plates are mounted within mating frame members 1 and 8, the main body of which are preferably of substantially Fig. 8 construction. The plates 1 and 8 are se cured together by rivets or'th'e like 9 and are pro-- vided withopening's there to receive the reflectors 2 and 3. The openings formed by the sides 1 and 8' are spread outwardly slightly as indicated at l0, Fig. 3, to form a seat for the peripheral edges of the signal plates 3 and 4 as indicated at I I, Fig. 3;

The signal elements 2 and 3 are each preferably formed of substantially transparent material having suitable outer faces and preferably prismatic inner faces [4 and I5 for reflecting and/0r refracting light rays impinging against the outer faces back approximately to their source of incident.

Formed integrally with the body of the plates 1 and 8 are extension arms I6 and [1, the free ends being turned laterally and then upwardly forming U-shaped members l8 and I 9 on the lower end of the plate, the U-shaped members having upwardly extending legs 20 and 2|. The legs are provided with spaced openings 22 and 23 through which extends substantially u-shaoed base supporting members 24 and 25 each having legs 26'- -2'l and 28*29, respectively. The outer ends of the legs are turned laterally forming hook members 30; the inner ends of the base members having across bar 3| which is curved slightly downwardly as best illustrated in Fig. 1. The ends of the u-shaped members 24 and 25 are turned laterally in the opposite section from the hooks 2'9 and the openings 22 and 23' the legs through the openings 22 and 23 until they reach the curvature of the legs of the base members as indicated at 32 and the cross bar 3i will engage in the U-shaped members i8 and t9, the hooks 29 and 30 of the respective base members engaging the highway or other support on which the device is placed. When the device is not in use the base members are pulled upwardly through the openings in the U-shaped members 18 and I9 and the hooks on the respective base members will substantially contact each other and the base legs will lie flat against the main body of the signal as best illustrated in Fig. 4.

In the modified form of the invention as shown in Figs. to 9, inclusive, 33 and 34 designate side plates comprising a frame, the side plates 33 and 3t being preferably made of sheet material such as metal, plastic or otherwise provided with the usual openings adapted tdreceive signal elements 35 and 36, the side plates being held together by rivets or the like 31. The signal element preferably consists of disposed plates 38 and 39 formed of colored glass or similar substantially transparent material having suitable outer faces and preferably prismatic inner faces 40 and di as in the preferred form of invention for reflecting and/or refracting light rays impinging against the outer faces back approximately to their source of incident. The openings of the frame members are provided with flanges as indicated at 42, Fig. 7, for receiving the peripheral edges of the signal elements also as shown in the preferred form of invention.

Secured to the lower ends of the frame of the sides 33 and 34 of the frame by welding or other suitable means are ears 43 spaced to receive the legs 4445 and 46-41 of U-shaped base members 48 and 49, also as illustrated in the preferred form of invention, the outer ends of the legs having hooks 50 to retain the base members in the ears 43. The inner ends of the base members 48 and 49 are turned laterally as indicated at 52 and are provided with slightly inwardly curved cross members 53 and 54, also as illustrated in the preferred form of the invention. a

When the device is intended'for use, the spaced members 48 and 49 may slideoutwardly through the ears 43 until the outwardly turned portion of the base member contacts the ears and the outer ends formed by the hooks 50 contacts the roadway or other support for the device.

In the form of the invention shown in Figs. to 14 inclusive, 55 designates a base member substantially rectangular, in shape having its sides turned downwardly forming flanges, 56 and 51 and provided with spaced openings 58-59 and 606l on the respective side edges as best illustrated in Fig. 10.? The base member is also provided with a boss 52 at substantially the center of the base member provided with openings 63 and 64, the respective ends of the upper portion thereof adapted toreceive the extensions or arms 65 and 66 of a frame 61 for retaining signal elements 68 and 69 one above the other. While I have here shown the signal elements to be substantially circular, any desired shape maybe used, and the frame El is shaped in substantially a figure 8 having plane surfaces 10 and. H provided with openings 12 adapted to receive a bolt 13. The edges of the frame are rounded and provided with side flanges 14 and 15 so as to engage and retain therein the signal elements 68 and 69 as is the usual practice. The arms or extensions 65 and 66 are secured to the boss of the base member by rivets or the like as indicated at 16. The bolt 13 is provided with threads 11 for receiving a threaded nut 18 for tightening the frame 61 onto the signal elements 68 and 69 to provide easy assembly of the structure. A U-shaped bracket 79 is provided for engaging it over the head 80 of the bolt to facilitate entry of the bolt into the openings of the frame member.

The signal elements 68 and 69 preferably are each formed of substantially transparent material having suitable outer faces and preferably prismatic inner faces BI and 82 for reflecting and/or refracting light rays impinging against the outer faces as in the forms of the invention shown in Figs. 1 to 9 inclusive.

A pair of supporting legs 83 and 84 are provided and are formed in substantially U-shape for engaging in the openings 58-59 and Gil-6| of the base member and adapted to slidably engage therein. The arms 85 and 8B of the U- shaped leg members are turned laterally of the legs so that when the legs are in supporting position the arms will lie substantially fiat along the upper face 81 of the base member 55 and engage against the respective sides of the elongated boss 62.

In assembling the device constructed as described, the arms 65 and 66 of the frame 61 are inserted through the openings 63 and 64 in the boss of the base 55 and riveted to the sloping sides 88 and 89 thereof. The signal elements 68 and 89 are inserted in the flanged portions of the frame and tightening of the bolt 13 between the signal elements will rigidly retain the elements in the frame and the frame on the base 55. The pairs of legs 83 and 84 are inserted through the openings in the base 55 and the outer ends thereof turned as indicated at 90 and BI to retain the legs in the base member and also provide a supporting base for the legs. The turned portions may be provided with rubber washers or the like if desired as indicated at 92.

The pairs of legs are slidable in the openings in the base so that the device may be folded as indicated in Fig. 14 for transporting in the car or other vehicle. When it is desired to use the signal, the leg members are merely extended downwardly through the openings in the base member until they assume the position shown in Fig. 10.

While I here have illustrated the framework for the signal elements to be made from sheet metal it will be obvious that any suitable material may be used. p

It will be obvious from the foregoing that I. have provided an improved signalingadevice which is compact, inexpensive to manufacture and eflicient in operation. 1
