7 Claims.

This invention relates to lamp standards and more particularly to a standard such as employed in gasoline service stations, and for the purpose of replacing the light bulbs, cleaning, etc.

the standard includes a hinge joint intermediate its height, permitting the upper portion of the standard to be swung into close proximity to the base upon which the standard is erected.

It is an object of the invention to provide a novel and simple construction of hinge joint which will accommodate the electrical wires for the lamps carried within the standard, without liability of setting up wear upon the insulation of the wires during breaking of the hinge joint,

and to further provide a hinge structure wherein the electrical wires may be readily threaded therethrough during assembly of the standard or for the purpose of replacing the wires.

It is a further object of the invention to provide a standard of the type set forth wherein the abutting ends of the standard are so constructed as to permit the standard to break the joint in only one direction of movement; and further to provide novel means for locking the swinging portion of the standard against movement.

It is a still further object of the invention to provide a swinging standard of the type described wherein sign supporting arms may be readily incorporated with the standard without liability of interference during breaking action of the standard, and wherein the signs may be adjusted to varying angles, as desired.

Additional objects, advantages and features of invention will be apparent from the following description and accompanying drawings, wherein Figure 1 is a side elevation of a standard construction in accordance with my invention.

In carrying out our invention, we provide a main standard Ill adapted to be supported in an erect position by having its base end secured in a foundation of concrete II, or otherwise as de- 10 sired. The standard I0, as shown in the present instance, is formed from hollow square tubing, and may be of any suitable length, and in practice the standard It] has been made approximately 14 feet in length from its base end to 15 the hinge joint of the completed standard, although such dimension may vary to suit the particular lighting problem involved.

Adjacent the base of the standard it there is a hole, suitably tapped to receive a conduit 12, 20 and through this conduit electric wires l3 are fed, which continue through the standard it to the light as will be presently explained.

As clearly shown in Figures 1 and 4, the standard NJ terminates at an angle of approximately 25 45 degrees, defining an inclined face M. A suitable distance downwardly from the face It the standard is provided with apertures l5 formed in opposed walls of the standard defining bearings for a swinging standard It, as will now be 30 fully described.

The standard I6 is formed from square tubing similar to that employed in the standard It, but of slightly less dimensions, and terminates at its upper end with any suitable fitting for support 35 of a conventional form of fioodlight, generally indicated at H.

The lower end of the standard I6 is cut at an angle similar to the angle of the standard H], defining a face 18. When the standard It is in its 40 normal erect position, the faces l4 and iii of respective standards will be in snug abutting relation and in such position, it will be apparent that the standard It may be swung in one direction only, as will be more fully set forth hereinafter. 45

Upon the outer faces of opposed sides of the standard Hi there are arms [9, which, as' shown are welded or otherwise secured to the standard [6. Thus, the arms l9 provide a yoke, generally indicated at 20, the arms being so spaced as to re- 5 ceive the standard In freely therebetween, but at a point in close proximity to the hinge joint of the standard, we prefer to have a frictional contact between the arms 19 and the standard l0, thus providing .a non-shaking assembly. The arms I9 win by a fiat integral bridge member 2|. The bridge member 2| is .apertured and receives therethrough a threaded bolt 22 carried by the standard It! and in order to maintain the swingingstandard |6 in its erect position there is provided a nut 23 cooperable with the bolt 22, the nut having bearing contact with the bridge member 2 I. Unauthorized persons may not release the swinging standard I 6, since the bolt 22 has an aperture therethrough, within which any suitable lock 22' may be engaged, preventing removal of the nut 23. The yoke 20 may be suitably reinforced by bridge members 2| similar to the bridge 2|, in order to insure a proper relationship between the two arms I9.

.Reference is now made particularly to Figures 3 and 4 of the drawings fora clear understanding of the hinge joint between the standards I9 and 16, generally indicated at H. Each of the arms l9 are provided with aligned apertures 24 adapted to register with the apertures l5 of the standard in and through these aligned apertures a bolt 25 is inserted. The bolt 25 has'a flanged head 26 7 having unequally spaced apertures and the adjacent arm I9 is similarly apertured'and tapped to receive machinescrews 21. Thus, the flanged head of the bolt may be snugly held in place against the adjacent arm and rotation of the bolt is prevented; and due to the unequal spacing of the screw apertures, the bolt'25 may only be installed inone position, for a purpose which will presently appear. The end'of the bolt 25 opposite the head 26 terminates flush with the adjacent arm i9, and an axial bore 28 is formed in the bolt 7 25 opening upon the end opposite the head and stopping short inwardly thereof a short distance. An arcuate slot 29 is formed in the bolt 25 at right angles to the bore 28 and opens upon the hollow standard l0 and disposed in-a direction to receive the wires |3 extending upwardly from the base I|. understood that the wires l3 are threaded through the opening 29 and thence the bore128exteriorly of the adjacent arm l9. The last named arm and the standard l6 are provided with aligned apertures 30 forming communication with the interior of the hollow standard l6, and through these aligned apertures the wires 3 are passed so that they may be carried upwardly through the standard to the fioodlight II. The provision of the slots 29permits swinging movement of the standard without distortion of the electrical'conbut'are disposed for a short distance upon the exterior surface of the arm l9 by reason of which the wires are relieved of wear during breaking of the joint. It is desirable, however, that some form of covering be provided for the wires where they pass from one standard to the other, and we therefore provide a cover plate 3|. The plate 3| is of cupped formation which, when bolted to the arm I9 by screws or the like, provides a passage 32 readily housing the wires'against exposure to the elements. If desired, agasket may be employed between the plate and the arm I9. The construction described also presents a simplified means for replacing wires as occasion demands,

as would otherwise be the case.

From the foregoing description, it will be electric bulbs contained therein may be readily replaced, cleaned or otherwise, by an attendant standing at the base of the standard. It will be noted that the standard |6 will be permitted to swing in one direction only, due to the abutting faces l4 and I8, and these faces in conjunction with the bridge 2| prevent movement in a reverse direction beyond a true erect position of the standards, which is essential when returning the standard Hi to its operative position. The breaking action of the hinge joint and swinging movement of the standard I6 may be controlled by means of a chain 33 secured to the bridge member 2|. The chain 33 is also employed to swing the standard |6 to erect position, so that the bridge member 2| will align with the bolt 22. When the standard |6 has been swung to such position, the nut 23 is screwed into position upon the bridge member and the lock 22' secured in the bolt 22.

In Figures 6 to 9, we have shown a modification of the standard, wherein sign supporting arms are incorporated with the standard. The standard is constructed as described in the first form, with the exception of the lower standard I0, which will now be described. The standard ID, as clearly shown in Figure 7, is constructed from a hollow square casing as before described,"v and within this casing there is a cylindrical pipe 35 which in practice hasbeen spot welded to the shell, at suitable points. The pipe '35 is of a length to extend from the base of the standard casing to a point slightly above the hinge'joint, and it will be readily apparent that a standard thus constructed will have ample rigidity for support of advertising signs,many of which are of considerable weight. w

Upon the standard l0, slightly below the hinge joint H there are mounted a pair of arms 36 and 3! disposed transversely of the standard and arranged in superposed relation, as clearly shown in Figure 6. These arms are preferably formed of cast steel and are welded to the standard upon a side thereof which will permit free swing ing movement of the arms 19 of the standard IS.

The arm 31 is provided at its'ends with apertures 38, and the arm 36 has formed at the extremities thereof recessed seats 54 in alignment with retures and engaged upon the seats there is positioned a leg 39 of a sign supportingbracket arm 40. It will be noted that the leg members are vertically arranged upon opposite sides of the standard l0, and that the bracket arms 40, which are in the present instance shown as continuations of the leg members, are extended at right angles thereto. The bracket arms are of a length to afford ample support for advertising signs, as

will be explained hereinafter.

v The legs 39 are adjustably retained within the arms 36 and '31, so that signs supported from the bracket arms 40 may be swung to various angles with respect to the standard, as indicated in dotted lines in Figure 9. In order to secure the leg members 39 in fixed adjusted positions, the arms 36 and31 opposite respective apertures 38 are drilled and tapped to receive set screws 4| which will impinge upon the leg members 39. Any suitable sign 'elernents may be suspended from the arms 40, and in the present instance we have shown circular disk elements 42 supported from the arms 40 by hangers 43. These signs will carry advertising matter upon opposite sides thereof and to make these signs discernible at night, the arms 40 are each provided with a pair of oppositely disposed brackets 44 supporting lamps 45. The sign elements being thus suspended in such manner that both sides thereof are fully illuminated from the lamps 45.

Various constructions may be employed for securing the brackets 44 to the arm 40, but we have illustrated a preferred form in Figure 8. In this form, we have shown a fitting 46 having opposed nipples 41 into which the arms 44 are secured. The fixture 46 in the present instance is of hollow formation, and comprises a saddle 48 having a semi-circular recess of a size to snugly seat upon the arm 40, and medially. of the saddle 48, the fixture 46 has a downwardly turned throat 49 adapted to engage within an aperture 50 formed in the arm 40. The fixture 45 is clamped in position upon the arm 40 by a clip 5|. From the foregoing, it will be apparent that the electrical conductors carried by the arms 46 may be readily threaded through the throat 49 and thence through respective bracket arms 44 to the lamps 4 5, which may be facilitated by removal of the cover plate 52. It will be apparent that the throat 49 engaged within the aperture 50 of the arm 40 acting in conjunction with the clip 5|, the fixture 46 will be positively held against oscillations or other movements and a secure connection between the arm 4|] and bracket arms 44 is established.

Attention is now invited particularly to Figures '7 and 11 of the drawings for further discussion of the construction of the arm 35. As has been previously stated, the arm 36 is welded to the standard In, and since this arm in addition to providing a pivot for the legs 39, defines a conduit for the electrical conductors, the arm is hollow, providing a channel 53 opening upon the seats 54. The arm 36 is also provided upon opposite sides with openings 55 and 55', the former opening registering with aligned apertures 56 and 51 formed in the standard l0 and tube 35, respectively. The latter opening 55 which is upon the exposed side of the arm constitutes ready means for gaining access to the wires for threading the same through the various apertures of the fixture and is closed normally by the cover plate 58. At the lowest point of the arm 36, a drainage aperture 36a is provided.

The electrical conductors are threaded through the standards l0 and I6 as in the first form herein described, but at a suitable point, the conductors l3 are tapped by wires extending from the lamp fixtures 45, such wires being threaded through the bracket arms 44, the arms 40, the legs 39 downwardly through the seats 54, the channel 53 and thence through aligned apertures 55, 56 and 51.

In Figure a modified form of base is shown, which may be found desirable in certain installations. In this instance, the standard [0 is provided with a foot 59 adapted to seat flush upon a supporting surface. The foot comprises a flat base 60, connected as an integral part of the standard by fins 6 l. The base 60 is suitably apertured and through each aperture there is engaged an anchor bolt 62 which may be embedded in concrete or otherwise. In the construction described, it is also intended to feed the electrical conductors directly through the base 60, as indicated by the conduit 63, and in order to facilitate splicing of the electrical conductors an aperture 64 is provided in the standard [0. A plate 64' may be employed to close the aperture, as shown.

While we have shown and described certain ,5
