This invention relates to an illuminated fence and more particularly toy such a fence which isA designed to enclose air portsand prevent the public from entering vthe-held and subjecting themselves to the danger of` same in landing. The illumination or the boundary -tence also clearly Ademarcates' the airport andV greatly assists the aviator in getting his bearings and making a safe landing at night.

A further object is to provide such a fence which is as low as is practicable for its purpose and in which all overhead wires are eliminated. Such overhead wires and obstructions cannot be seen fromjtherapidly moving` airplane, particulairly4 at night,` and j constitutea very dangerous hazard about an airport. Moreover, due to the angle at which airplanes land, everyy obstruction cutsv oli" seven times Yits length in theetf'ective area of4 the airport andconsequently' ally 'such obstructions, such as wires and the like, greatly y intermediate post l() is adapted 'to connect `the against the weather and accidental injury.

A further aim is lto provide a fence otthis character. which isk vprovided. with covered openings permitting' the concealed 'wires' to be repaired readily` at their place of kconnection with the electric light Xtures'thereby facilitatingl the installation, inspection' andrepair ofthe wires.

Other aims are toprovide such a'fence whichv is extremely strong, which is composed of vvinexpensive parts and can bev erected with little expense, thereby 'permitting of the installation of such fences withadequatelyv` protected j inthe curtailed appropriations usually made for airports. f ln] the' accompanying drawings :y Figure l isa fragmentary side elevation or an. airport fence made in accordance with myinvention. Figure 2 is a fragmentary side elevation of the fence' at the place orA juncture'between the'posts, the horizontal rails and the elec'- tri'c iixture. j

clude tubular intermediater supporting posts 10tubular rails ll `between these posts and hollow ,fittings l2 connecting the upper ends ofthe posts and the rails.. The posts are suf'- Aiiciently heavyto provide a durable support for the fence andthe lower end of each post is setinto a concrete base Aor bed YV1"?) in the ground. This concrete base or bed preferably'y completely surrounds and seals'thel-owf er endof the vpost and terminates at 'the ysurface ior'the' ground in the usual manner, c

Each of the tlttings'l?l at the top of each post with the two adjacent rails 11 `and as best shownL in Figs. 2-5 is formed to provide a downward tubular `extension lli and two laterallyextending-portions l5. The downward tubulareXtension is adapted to receive the Vupconduit which is adapted to receivethewires perE end of theintermediate post' 10 and to supplying electricity for illuminating the fence.

At suitable intervals gates are provided in vthe fence and for this purpose gate posts 18 are provided which are similar tothe intermediate posts 10. Each gate post is c-onnected with the adjacent rail 11 by a litting 19 which is similar. to the fittings 12 of the intermediate posts except that the gate post fitting 19 is provided with only one lateral tubular extension since it only connects with one rail. 1

rlhe gate 2O may be of any suitable construction and is hung on hinges 21 which are carried by one of thegate posts. To hold the gate in its closed position any suitable form of latch 22 may be employed to secure the gate to the other gate post and prevent the same from being opened exceptwhen released.

Both the gate 2O and the fence framev are covered by a wire fencing 2S which is preferably-of the chain or link type. This fencing is preferably secured to vertical end bars 24 and is secured at intervals to the fence rails 11. Each of the end bars against which the wire fencing 23 is drawn is preferably rigidly securedvto the corresponding gate post 18V by brackets 25 so that the fencing is securely l held at its ends. In a similar manner the wire fencing covering the gate is held between two bars 26 connected byebolts 27 to the gate frame and is secured atits upper and .lower edges to the upper and "lower rails of the gate.

At the lower ends of the gate posts 18, elbows 28 are provided and to these elbows is secured a. pipe 29 which extends between the gate posts and forms a subterranean conduit therebetween. 'Y

Each of the fittings 12 and 19 at the upper end of the fence posts is provided with an upwardly extending internally threaded neck 30 which forms a socket for the reception of l' through an underground conduit 34E which is connected with any one of the fence posts. The wires fromvthis conduit pass up through Y the fence post andrun along through the tubular rails 11 and the fittings 12 and 19 as indicated in Fig. 1. When a gate is encountered, the wires 34; are passed through the litting'19'atthe upper end of the gatepost 18,

down the gate post 18 across the underground pipe 29 connecting the lower ends of the vgate served that the wire is at all times carried within the members forming the fence, and are adequately protected from the ei'iects oi 'weather or other injuries. Y .Y By providing an underground conduitto the fence, all overhead wires are eliminated and consequently this hazard to the safety of aviators is avoided.

Each ofthe electric light iixtures 32 is provided with the usual wires 36 which extend through the neck 31. These wires as indicatedin Fig. l are connected in parallel with the line wires 34 in the usual manner and consequently all of the lights arel illuminated from the main line wires. To facilitate the threading of the line wires 311 through the fence members and also to permit of connecting, inspecting and repairing the fixture wires 36 connected therewith, openings are provided at one side of each of the fittings 12 and 19 which .openings are, covered by plates 37.

These plates are secured in place by screws d8y or in any other suitable manner.

As a whole this invention provides a fence for airports or the like which is adequately illuminated by lights arranged ateach fence post and in which there are no exposed or overhead wires. The fence is also extremely simple and durable in construction and can be erected 'at low cost. f

I claim as my invention:

1. A fence composed of open ended hollow post members, open ended hollow rail members, hollow fittings connecting said post and rail members, said rail members and hollow fittings jointly providing a continuous, uninterrupted, enclos-ed conduit along the fence, a plurality of electric lights spaced along the fence rail and supported by the fence and electric wires arranged in said conduit and connected with said lights.

A fence composed of a plurality of tun bular posts, a'concrete base supporting each of said posts, tubular rails between said posts, hollow fittings mounted on the tops of saidV posts and receiving the ends of said tubular rails, said fittingsforniing with said rails and posts a continuous, uninterrupted, enclosed conduit and said fittings being formed to receive the bases of electric light fixtures, wires arranged in said conduit and extending the entire length of the fence and connected with each of said electric light fixtures and wire mesh fencing carried by said rails and posts. v

- end of the corresponding rail, an abutment limiting the inward movement of the corresponding rail relative to said fitting and an upward extension adapted to receive the base of' an electric light fitting, said posts, fittings and rails together forming a continuous conduit, electric light fixtures carried by said fittings, wires arranged in said conduit and connected with said fixtures and a wire mesh fencing carried by said rails and posts.

6. A fence composed of a plurality of tubular posts, a concrete base supporting each of said posts, tubular rails between said posts, hollow fittings mounted on the tops of said posts, each of said fittings comprising a downward tubular extension receiving the and receiving the ends of said tubular rails.l said fittings forming with said rails and posts a continuous conduit and said fittings Vbeing formed to receivel the bases of electric light fixtures, wire mesh `fencing carried by said rails and posts, a cross conduit connecting the lower ends of said gate posts and an electr-ic wire extending throughsaid tubular rails, fittings, gate posts and the conduit connecting the lower ends of saidy gate posts, said wire being connected with each of said electric light xtures.

In testimony whereof I hereby affix my signature. n
