Fig. 7 is a perspective view showing another embodiment of the present invention.

Referring to thedrawings, the barricade is shOwnconsisting of a standard 10, supporting a sign frame 11 comprised of a pair of substantially identical vertical side members'12 (only one of which is shown in the figure), a lower horizontal frame member 13 and an upper horizontal frame member 14. The members 12, 13 and 14 may be any suitable form of shafting, such as conventional water pipe which is readily obtainable anywhere in the country. At its upper end, each vertical member or shaft 12 is secured to the respective ends of the upper shaft or pipe 14 by a conventional pipe elbow 16 into which the pipes 14 and 12 are threaded. If desired, the joint at 16 may be prefabricated by being welded. Within the space outlined by frame 11 is secureda flat sign 17, which may be made of. sheet metal or other suitable sheetlike mateiral. The sign 17 has a pair of tubular sleeves 18; formed at each side thereof, which encircle the respective vertical shafts 12 to secure the sign 17 in place in the frame 11.

At their respective lower ends, the vertical shafts '12 are secured to the respective ends of the lower horizontal shaft 13 by'a special joint 19 constituting an important feature of the present invention. As seen in detail in Fig. 2, the joint. 19 comprises a body having three angularl'y spaced socketportions 21, 22, and 23, the axes of which are disposed generally co-planar in a vertical plane. Substantially at the common intersection of these three socket axes is the axis of another socket, i. e., a horizontal socket 24. The socket 21 extends directly upward and receives the vertical shaft 12 constituting a portion of the frame 11. The socket 24 is at right angles to 'the socket 21 and receives the horizontal shaft 13 of the frame 11.. Thus the socket 19 serves (among other functions) the purpose of forming one of the corner joints of the frame 11.

The sockets 22 and 23 are directed' generally downward' but diverge symmetrically away from the vertical axis of the upper socket 21, so as to receive shaft members 26 and 27, respectively, constituting two of the legs of .the standard supporting sign frame 11. It will be understood that the other end of the sign frame 11 is similarly equipped with a socket 19 and with legs 26 and 27. At their bottom ends, the legs 26 and 27 are provided with horizontal extensions 28, whichserve to give the barricade greater stability particularly ainst high winds blowing against the face of the sign 17, which tend to tip the barricade over.

Directly opposite the socket 24, the joint 19 is provided with a substantially fiat, vertical face 29. Inthe face 29 are three substantially horizontal tapped or threaded bores 31, 32 and 33 communicating with the interiors of the respective sockets 21, 22 and 23. Threaded in the bore 31 is a set screw 34 which secures the shaft or pipe 12 in the socket 21. To this end, the pipe 12 is-provided with an aperture'36 through which the set screw 34 passes, the inner end of the set screw 34 abutting against the inside opposite wall of the pipe 12, which is not apertured. In order to permit the set screw 34 tobe recessed in the face 29, the set screw 34- has a socket type head as illustrated at 37.

The legs 26 and 27 are similarly held in place in their respective sockets 22 and 23 by similar set screws 36 threadedly secured in the respective bores 32 and 33, as. shown in Fig. 5.. Likewise, the horizontal pipe 13 is secured in its socket 24 by a set screw 39 threaded in a tapped bore 41 formed'in the upper wall of the socket 24.

In order to maintain the legs 26 and 27 in proper position :during assembling of the barricade so as to prevent these legs from blocking full entranceof the shaft 13,

stop bosses 42 are formed on the inside of the joint 19, as shown in Figs. 5 and 6, against which the legs 26 and 27 abut, and are thus limited in their inward mounting in their respective sockets.

The fiat face 29 of the joint 19 also has a fourth threaded bore 43 generally centrally located therein and communicating with the interior of the joint 19. Disposed flush against the face 29 is a generally rectangular lampreceiving fixture box 44, one side 46 of which rests flush against the flat face 29. The box 44 is secured to the joint 19 by means of a bolt (Fig. 4) which passes through an aperture 48 (Fig. 2) formed in the side 46 and is threaded into the tapped bore 43 of the joint 19. The side 46 is also provided with three apertures 49 which register respectively with the three tapped bores 31, 32 and 33, in order to give access to the ,set screws 34 and 38, after the box 44 has been secured in place.

Extending symmetrically from each side of the face 29, the joint 19 has a pair of ears, 51 and 52 provided with apertures 53 and 54 respectively. As will be seen in Fig. 2, the opening 48 in the side 46 of the box 44, with its associated openings 49 is not centrally located in the side 46; therefore the box 44 extends asymmetrically out from the joint 19.

In that portion of the side 46 extending asymmetrically out from the joint 19, there is provided an aperture or opening 56 which registers with the aperture 54 in the ear 52. A warning iamp 57 is disposed in the box 44 and is provided with a reinforced nut 58 (Fig. 3) welded thereto which receives a securing bolt 59 therein passed through the ear 52 and the side 46 as seen in Fig. 3. The bolt 59 serves to prevent removal of the lamp 57 from the box 44. In order to prevent unauthorized loosening and removal of the bolt 59, the head 61 of the bolt 59 is covered by a locked cover 62, which is held in place by a lock controlled finger 63 engaging in a slot in a s ecially formed washer 64 placed under the head '61. In thisway, the bolt 59 may not be unscrewed except by one having access to the locked cover 62 by means of a key 66.

In order to further fortify the box 44 against unauthorized removal of the lamp 57, the open top of the box is provided with inwardly extending flanges 67 which overlie the housing portion of the lamp 57 but which still permits the upward protrusion of the dome portion 68 of the lamp. One end of the box 44 is open but the other is closed by a strap 69 welded thereacross between the side walls of the box.

Loosening of the bolt 59 by rotation of the locked cover 62 is prevented by the sockets 21 and 22 of the fitting 19.

From the above description it will be seen that the joint 19 serves the multiple purpose of securing together the lower portions of the frame 11; of receiving the barricade legs 26 and 27; and of supporting the fixture box 44. It will also be seen that the joint 19 constitutes a medium by means of which the barricade may be held in assembled position against unauthorized disassembly, and by means of which the box 44 and warning lamp 57 may be secured to the barricade against unauthorized removalall with a single locking member 62. When the locked cover 62 is removed, not only is access provided to remove the lamp 57, but such removal of the lamp 57 also gives access to the securing bolt '47, by means of which the box 44- may be removed if desired, and to the set screws 34 and 38, which permit disassembly of the barricade structure for easier transportation and storage. It will be further noted that it is not necessary to remove the box 44 in order to remove the set screws 34 and 38, since they may be taken out through the apertures 49, even with the box 44 in place.

It will be further noted, particularly by reference to Fig. 4, that the presence of the sheet metal sign 17 blocks access to the set screw 39, so that the horizontal shaft 13 may not be removed without authorization. The sign 17 is taken out of the way simply by removing the set 4 screws 34 and lifting the vertical shafts 12 from their respective sockets 21.

The configuration of the fitting 19 makes it possible to easily bolt a line of barricades together to form a long structure that may extend continuously across a road. This is done by removing the box 44, through removal of the bolt 47; and butting the face 29 of one barricade against the face 29 of an aligned barricade. Securing bolts may then be passed through one or both of the holes 53 and 54 and secured in place by nuts. Locks may be provided for these bolts and nuts if desired.

it will therefore be readily apparent that there has been provided a simple barricade structure, the key to which is a readily cast joint, so constructed that a single lock member serves to prevent the slightest unauthorized disassembly of the barricade, yet which, when properly authorized, one may completely knockdown to its elemental components for ready transportation and storage.

The fixture box 44 is not limited in its use to a barricade structure of the type illustrated in Fig. 1, but may be welded atop a single upright vertical member '73, as shown in Fig. 7. The upright 73 is supported by a standard (not shown), and serves to hold in visible position a flashing light 57 which is locked in place by a locked bolt cover 62 as illustrated before. While the same style box as shown in Fig. 2 may be employed for this purpose, it is preferred to omit the holes 48 and 49, and to provide the side 46 with protrusions or dimples 74, which bracket the lock cover 62 and prevent rotation thereof, thereby guarding against unauthorized loosening of the securing bolt 59.

While the instant invention has been shown and de scribed herein in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention which is therefore not to be limited to the details disclosed herein but is to be accorded the full scope of the claims.
