ARM ATTACHMENT DEVICE Filed Aug. 25, 1960 54 Z4 4I I @i 3 lNvENToR @www {17m/54s BY ATTORNEY United States Patent O 3,104,122 ARM ATTACHMENT DEVICE Gordon E. Daniels, Nashville, Tenn. (7600 Twining Drive, Knoxville 19, Tenn.) Filed Aug. 25, 1960, Ser. No. 51,907 2 Claims. (Cl. 287-54) This invention relates to a device for attaching an arm to an angular surface formed by the intersection of a pair of plane surfaces, and more particularly to a device for attaching the bracket arm supporting a luminaire, or other lighting unit, to one pair of intersectin-g faces of a lighting standard or pole having a polygonal cross section.
Heretofore, a luminaire bracket arm has been attached to Ia lighting standard or ilamp pole having poly-gonal, and conventionally octagonal, cross sections, by providing a plate member having three faces disposed at the same angle as the angles formed -by three of the pole faces so that the plate member could fit ilush against the pole. One important disadvantage of this type of attachment device is that a diiferent device must be made for poles of different diameters, even though the angles between the faces remain the same.
It is therefore an object of this invention to provide 'an attachment device for securing a luminaire bracket arm to a light or lamp pole having a polygonal cross section comprising `a plate member having only two faces intersecting at the same angle as a pair of corresponding pole faces, in order that the member may lit ush against the corresponding faces of any similar-shaped pole regardless of size.
Another object of this invention is to provide a device for attaching anarm to a light pole in which the larm may be temporarily suspended in operative position While it is being permanently secured to the pole.
Another object of this invention is to provide an arm attachment device for a light pole which is of simple and economical construction and adapted to .facilitate the assembly of the arm to the light pole.
Further objects yand advantages of the invention will be apparent from the following description taken in conjunction -with the drawings, wherein:
FIG. 1 is an exploded assembly view of the invent1on;
FIG. 2 is a side elevation of the invention;
IFIG. 3 is a view similar to FIG. 2 with parts broken away to show the attachment `device in section, and showing an operational position in phantom; and
FIG. 4 is a section taken Ialong the line `4-#4 of FIG. 2.
Referring now to the drawings in more detail, a novel attachment device is disclosed supporting a luminaire bracket arm 11 on a conventional Ilighting `standard or light pole 12 of regular octagonal cross section. It will be noted that the attachment device 10 is secured ush against only two adjacent pole faces y13 and 14 forming an interior angle of l135 The attachment device 10' comprises essentially two plate members, a pole plate 117, ladapted to abut flush against the pole faces 13 and 14, and an arm or shoe plate 1S, adapted to abut flush against the pole plate `17. rlhe pole plate 17 comprises two plane plate sections 19 and 20 joining each other at the same angle as the pole faces 13 and 14, which would be 135 for a regular octagonal pole 12. The upper portion of the pole plate A17 forms an outwardly extending ilange 21 having a down-turned lip 22 spaced from rand substantially parallel to the plate portions -19 and 20 a distance slightly greater than the thickness of the shoe plate 18.
The pole plate 17 is provided with a longitudinal opening -23 having substantially straight sides and circular ends and having its longitudinal -axis coinciding with the intersection of the plate sections 19 and 20. The opening 23 lee is provided with a peripheral flange or lip l24 extending inwardly to tit Within a similar opening formed in the pole faces 13 and 14 so that the pole plate 17 may be held in alignment while it is being welded to the pole faces 13 and 14 for permanent attachment.
The shoe plate '18 also comprises two plane plate sections 25 and 26 joining at the same angle as the angle between the pole plate sections 19 and 20. A similar opening 27 of the same size and corresponding position as the opening 23 is formed in the shoe plate sections 25 and 26 so that the longitudinal axis of the opening 27 coincides with the line of intersection of the plate sections 25 and 26.
As best disclosed in FIG. 3, the base of the arm 11, which preferably has a circular cross section is inserted into the opening 27 at an angle to the longitudinal axis of the opening 27 so that the arm 11 will extend upwardly and outwardly from the pole 12 when secured in position by means of the attachment device 10. The base of the arm 111 may -be secured in place by any convenient means such as the Weld 30.
In order to assemble the shoe plate 18 and the pole plate 17, a circular recess 32 is formed in the pole plate 17 at the intersection of the plate sections 19 and 20'. A pin 33 extends from the inside of the corresponding position in the shoe plate 18 in such a manner that when the pole plate and the shoe plate 18 are nested flush against each other in aligned operative position, the pin 33 will be slidably received Within the recess 32, as best disclosed in FIGS. 3 and 4. The pin 33 is strong enough to support the combined weight of the shoe plate 18, the bracket arm 11 and the luminaire, not shown, attached to the `extreme end of the arm y11. The pin 33 and recess 3-2 are designed primarily as a temporary means of supporting the shoe plate 18 and the arm 11 until the shoe plate may be permanently attached to the pole plate 17. -One preferred method of permanently attaching the plates 17 and 18 is to provide the pole plate 17 with a pair of tapped holes 34 and 35, one in each plate section 1-9 and 20, respectively, 4and a pair of smooth openings 36 and 37 formed in the same relative positions in their respective plate sections 25 and 26 in such -a manner that they will align with the tapped openings 34 and 35, respectively. The pole plate 17 and the shoe plate 18 are then held in place by a threaded bolt 38 extending through and engaging the aligned smooth hole 36 and tapped hole 34, anda second threaded bolt 39 extending through `and engaging the aligned holes 37 and 35. Bosses 40 and 41 are formed on the plate sections 19 and 20, respectively to extend the tapped openings 34 and 35 through mating openings in the pole faces 13 and 14.
By employing the elements thus far described, the assembly of these elements for attaching a conventional -lurninaire bracket arm 11 to an octagonal lighting standard or light pole 10 becomes simple. After the light pole `12 has been manufactured the pole plate y17 may be Welded in place so that its plate sections 19 and 20 will fit ilush against their respective pole faces -13 and y14, with the llange 21 extending outwardly. After the luminaire bracket arm 11 has been manufactured, it may be permanently fixed at any desired angle to the -shoe plate 18 by welding its face at 30 in the longitudinal opening 27. With these elements thus pref-abricated, they may be transported to their destination and the light pole 12 erected in its permanent location. The arm 11 4welded to its shoe plate 18 is then elevated to the phantom-line position of FIG. 3, where the upper edge of the shoe plate '18 is inserted behind the lip 22 and up against the ilange 21. The shoe plate 18 is then rotated toward the solid-line position of `FIG. 3 against the pole plate 17 lwith the pin 33 sliding into its mating recess 32. With 4the combined weight of the shoe plate 18 and the arm 1.1 and the luminaire fully o supported and in proper alignment, by means of the pin 33 and the recess 32, the shoe plate 18 may easily be permanently attached to the pole face 17 by inserting and fastening the bolts 3S and 39 through their respective holes. The flange 21 and lip 22 not only guide the shoe plate 18 into position and limit its upward movement, but also to a certain degree prevent the shoe plate from kicking outwardly while it is being vbolted in place because of the leverage of the luminaire and its arm 11.
As previously mentioned, the arm attachment device 10 made in accordance with this invention is more adaptable for mass production because of its universal application to light poles 12 of different diameters having similar shaped cross section. =For example, the particular device disclosed in the drawings for an octagonal light pole may be readily adaptable to any regular octagonal light pole regardless 0f its cross sectional dimensions.
It -will be apparent to those skilled vin the art that various changes may be made in the invention, without departing from the spirit and scope thereof, and therefore the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended claims.
What is claimed is:
