eeee 9.9996996 ADJUSTABLE SIGNAL HANGER AND DOUBLE DOOR TERMINAL DISCONNECT HOUSING FIELD OF THE INVENTION This invention relates to traffic signal devices and, more particularly, to an adjustable length double door terminal disconnect housing connected to the hanger.

BACKGROUND OF THE INVENTION In the past it is often required that the signal lights at an intersection to be controlled by traffic lights be arranged at a height which'varies somewhat from location to location. This gives rise to the need for an adjustable length hanger. In the past great difficulty has been encountered in providing a hanger to suspend the electric signal lights from a cable and to arrange the length of the hanger so.that the lights are at the desired location. I

It is an object of this invention to provide a device which includes a readily adjustable hanger length, the hanger being composed of first and second member which are adapted to be extended or retracted in generally telescoped relation to adjust the overall length.

In the past it has also been rather difficult to do electrical work in the relatively confined interior of a conventional terminal disconnect housing for traffic signals. This invention provides a housing having opposed doors each of which doors carries on the inside surface thereof a terminal section which, when the door is swung open, is accessible for ready electrical connection of leads so that the doors may then be closed with the connections protectively housed within the interior of the box.

It is an object of this invention, therefore, to provide an electrical traffic signal terminal disconnect housing in combination with a hanger, preferably which is adjustable, which includes the above-referenced swinging doors with carried terminal blocks.

In the past because-of inclement weather in certain locations, such as in hurricane prone areas, it is often necessary or desirable to remove the signal lights from the hanger and terminal disconnect housing and, to this end, the present invention provides a removable floor section and means for quickly disconnecting the floor section and the electrical signal together with a male plug which connects to the terminal blocks on the housing so that the traffic control devices may be readily removed until the inclement weather has passed.

In accordance with these and other objects which have become apparent hereinafter the instant invention will now be described with reference to the accompanying drawings in which:

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an elevation view illustrating the hanger and terminal housing attached to a suspension cable;

FIG. 2 is a view similar to FIG. 1 and illustrating a side elevation view thereof,

FIG. 3 is a view in cross section taken on the plane indicated by the line 3-3 of FIG. 1 and looking in the direction of the arrows;

FIG. 4 is a view of the terminal box illustrating the opposing doors in opened relation for easy access to the terminal blocksmounted on the inside surface of the doors;

FIG. 5 is a view in cross section of the interior of the box or terminal housing portion of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, the numeral 12 generally designates an extendible signal hanger and the numeral 14 generally designates a terminal disconnect housing, while the numeral 16 comprises the zone of the means to connect the hanger and housing.

Referring specifically to the hanger, it is seen to include (a) a first elongate member 18 with an upper end and a lower end 20 and 22, and (b) a second elongate member 23 with an upper end 24 and a lower end 26. It is noted that along the length of the elongate members a plurality of holes such as that designated by the

numeral

28 and 30 are provided, the holes being equispaced and adapted to register with one another to vary the length of the hanger and to be secured together in a selected overall length by means of through

bolts

34 and 36 at the upper end of the first member and the lower end of the second member and secured by means of

nuts

38 and 40 with

lock washers

42 and 44 being utilized. The longitudinally extending

edges

46 and 48 of the first member and 50 and 52 of the second member are preferably V-shaped as seen in cross section and are of companionate or mating size for nesting sliding land and groove relation upon extensible movement of the members relative to one another, the said longitudinally extending edges also serving as rigidifying means for the hanger members. Means are provided on the upper end 20 of the first member for pivotal connection as at 54 with a cable engaging support 56 having a clevis type connection defined by a pair of

spaced legs

58 and 60 which at their upper ends extend outwardly into a laterally extending groove shaped segment 62 which is adapted to nest a cable 63 therein to be engaged and fastened by the

U-bolts

64 and 66 and in turn secured by nuts such as 68 and lock washers 70. The pivot pin is preferably secured by a cotter pin as indicated by the numeral 72.

In the preferred embodiment clamp means are also provided intermediate the hanger length for connection of it to a stabilizing cable 74, the clamp means being designated by the numeral 76 and preferably being composed of a pair of blocks, a first block and a

second block

78 and 80 each of which has holes extending laterally therethrough as at 82 and 84 to receive bolts, nuts and lock washers as at 86. Each of the blocks of the clamp has a groove in mating relation with one another to receive the stabilizing cable indicated by the numeral 74, the said grooves being indicated by the numeral 90, whereby the same may be tightened securely to the hanger members and clamp as illustrated.

In the preferred embodiment of the hanger, the lower end 26 is provided with a hub and a reinforcing segment or web 102. The hub has a plurality of radial 3 a clamping connection on the opposite sides of the reinforced roof 109 of the housing. I

Referring to the housing, it is seen to include a floor 116,

end walls

118 and 120, each of which end walls has an opening 101 and 103 to accommodate electrical lines, and, also, oppositely facing

side doors

120 and 122 which are hingedly connected to the end walls as indicated at 130 and 132. The interior surface of the doors are provided with a plurality of terminals secured thereto for electrical lead lines, such terminals being indicated by the numeral 140 and preferably including a female plug as at 143 for receiving the leads connected to a companionate male plug 145 of a traffic signal box. Lock means in the form of a bolt 147 are provided to secure the door in a closed position.

In the preferred embodiment the floor of the housing has a first portion, the main portion 116, and a removable portion 150 with a through hole 151 so that the removable portion of the floor may be slidably engaged with the main floor portion when installed and secured by the keeper 99 of the door. Additional lock means 154 arealso provided to secure the removable floor portion to the housing, these means being in the form of rotatable members pivotally connected to the main floor.

It is thus seen that there is provided an extendible length hanger and a double-door terminal box to which a traffic signal is adapted for ready accessible electrical and supported connection and which is also adapted to be quickly removed from the hanger and terminal box during inclement weather by reason of the partial floor which is removable and the male and female plug connections.
