No. 345,403 20 Qlaims. (CI. 52-38) ABSTRAET OF THE DISCLUSURE This invention pertains to light and multi-service utility standards, and particularly to the cross-sectional shape of the shaft and the arm; the means for assembling and nesting the arm within the confines of the shaft; the structure of the base; and the means for holding the shaft to the base.

Our invention relates in general to light and multi service utility standards, and more particularly to the cross sectional shape of the shaft and the arm; the means of assembling and holding the arm to the shaft; the structure of the base; and the means of holding the shaft on the base.

Heretofore in municipal lighting and utility pole systems there have been no standardization of base, shaft, arm and the attachment to them of the various utilities which normally are spread throughout the streets of a city, and no effort has been made to establish a single base-shaft-arm combination capable of carrying all the utility items required in municipal life.

Therefore, with the idea in mind of a general utility standard, we have striven to create a structure capable of carrying and having easily assembled thereupon all the normal utilities. In addition, we have especially desired to construct a standard or shaft and base combination which is easily assembled, structurally sound and strong, which does not lend itself to thievery and malicious mischief and which is relatively inexpensive to purchase, economical in erection and maintenance and has a long life span. In addition, a further aim or purpose has been to create a utility standard which, while giving the maximum strength for a minimum of material, also results in a neat, trim, graceful and pleasing structure which enhances the appearance of the street upon which it is erected.

A further purpose is to provide a base housing for carrying a shaft and for encasing electrical equipment such as a transformer, of a transformer base and a shoe base and having them secured together by screw means which are entirely within the base.

Another purpose is to shape or contour the cross section of the shaft and arm so that the arm can nest in the shaft to add structural strength to the standard, the assemblage and the joinder of arm and shaft and further to permit an inexpensive and easy joinder of the arm and shaft.

An additional object is to firmly secure the arm to the shaft by means of a bracket positioned at the .lower end of the arm and at an intermediate position of the shaft and a screw and inset positioned at the upper end of the shaft and at an intermediate position of the arm.

A further purpose is to provide a bracket retaining the lower end of the arm and shaft together, which is designed in such a manner that only a single screw is required to secure the elements. Also, the bracket is provided with an opening to permit electrical wires to be drawn easily through the shaft into the arm.

Another object is to provide a rigid, strong shaft with a minimum of cross sectional area by disposing a high percentage of the sectional area at a distance from the center of the shaft. 7

Another object is to provide a unique, easily assembled and strong means of securing the arm to the top of the shaft.

An additional object is to provide a retaining means for supporting an alarm box or other utility having a gripping element so that the means can be easily attached to the shaft.

A further object is to provide a-traffic directional signal box casing with a simple attaching means for securing said box to the end of the shaft.

These and other objects are accomplished by forming the multi-service utility standard of a base, a shaft, an arm, and means for securing said arm and shaft together, said base being formed in two sections interiorly screwed together and the upper section thereof having a well, suitable for carrying and supporting the shaft, said shaft end being seated in the well and adhesively bonded or welded to its sides, and said shaft having a cross sectional shape comprised of two longer opposing convex arcuate sections and two shorter opposing concave arcuate sections joining the ends of the convex sections into a closed hollow shape, and the arm having a circular or arcuate cross section suitable for nestling in one of the concave sections of the shaft, and said securing means having a bracket securing the lower end of the arm to an intermediate portion of the shaft and an insert, saddle and bolt securing an intermediate portion of the arm to the upper end of the shaft whereby the base, shaft and arm are rigidly and strongly secured together into a standard which can be used to support street lights, directional signals, street name placards, police and fire boxes and any other desired utility.

For further comprehension of the invention and of the objects and advantages thereof, reference will be made to the following description, the accompanying drawings and appended claims in which the various novel features of the invention are more particularly set forth.

FIGURE 11 is a variation of the cover plate and includes a directional signal box casing.

In the drawings and in the specifications, in which like numerals indicate similar elements, our multi-service utility standard 20 (see FIGURE 1), is shown comprised of a hollow base 21, shaft 22, arm 23, a securing means 24 for holding the arm in rigid position adjacent the shaft and a utility box support 25. In general, the standard is assembled and positioned by anchoring the base to the ground, adhesively bonding or welding the lower end of the shaft 22 into a well or seat 26 centrally disposed in the base, positioning and rigidly securing the arm to the shaft by the securing means 24 at both the lower end of the arm and an intermediate position of the shaft and at the upper end of the shaft and an intermediate position of the arm, and by securing the utility box support 25 to the shaft. The base is anchored to a foundation or the ground by nuts 27 and bolts 28 protruding from a foundation and extending upward through ears or lugs 29 of the lower section 30.

The base 21 (see FIGURES 7 and 9) is formed of the lower section 30, sometimes called the transformer base as it normally houses a transformer, and an upper section 31, sometimes called a shoe base. The upper section rests on the lower section and the two are secured together by interior bolts 32 which extend upwardly through ears 33 in the lower section into solid portions of the upper section. The lower section is provided with a trap door 34 hinged for movement by the studs 35 extending into the inverted U seats 36 A lock also is provided for the door 34, consisting of a bolt 37 with an upset end 38, a plate 39 having a lip 40, and a stud 41 positioned on the lower section which acts as a stop for the lip 40. The bolt 37 extends through the door and is screwed through the plate above its center of gravity. The catch 42 for the lock is a downwardly extending projection positioned in the lower section at the top of the trap doorway and slightly in back of it. The lock is manipulated to open the door by screwing the bolt 37 so that the plate 39 retreats enough to permit the top of the door to clear the base face when the bolt is pulled forward. The door is then lifted out of the inverted U seats 36. Closure of the door is made simply by having the plate at a position farthest from the door, then positioning the door adjacent the doorway with the plate in back of the catch 42, then lifting the door and rotating its bottom portion so that the inverted U 36 seats on the studs 35 and then rotating the top portion of the door into position and screwing the bolt 37 until the plate is snugly against its rear. This closure and locking means is easily manipulated by one educated to the process but difficult to the unskilled. Furthermore, the door itself is not a likely subject for malicious mischief or thievery as the elements are (of no general interest or other of multiple use. Thus the transformer or other devices in the base can be approached easily as well as the bolts 32 which hold the shoe base to the lower base section.

The shaft 22 (see FIGURE is hollow in order to carry the necessary electric cables and has a cross sectional contour formed of two longer convex arcuate sections 43, spaced apart, and two shorter concave arcuate sections 44, spaced apart, and contiguous with the convex sections, so that the outline'of the cross section is actually convex, concave, convex and concave. This shape is structurally strong because of its large section modulus and resists torsion because of the positioning of the concentration of material at the junction of the arcuate sections. Furthermore, it provides reduced wind resistance and permits the arm 23, which is round and fits into the concave section 44, to be nested therein. This nesting, together with the securing means 24 (hereinafter described), rigidly and strongly retains the arm and shaft together. The arm 23 is, of course, hollow to permit the electric cables (not shown) to pass upward into a luminaire (shown dashed) or other fixture at the end of the arm.

While FIGURE 10 shows a shaft whose corner sides are arcs of an ellipse (or arcs of circles not having a common center), the corner sides may be in the form of arcs of a circle having a common center.

The securing means 24 (see FIGURE 2) is comprised of two parts, one of which is formed of a bracket 45 (see FIGURE 3) and a bolt 46 functioning together to retain and support the lower end of the arm against the shaft; the other is comprised of an insert 47 (see FIGURE 6), saddle 4-8 and bolt 49 functioning together to secure the arm to the upper end of the shaft. The two parts, functioning at a distance apart, together with the nesting, admirably support and retain the arm and shaft in rigid fixed position.

The hollow L shaped bracket 45 (see FIGURES 3 and 4) has an upwardly extending circular section 50 which fits tightly inside the end of the arm and a shouldered seat 51 upon which the end of the arm rests. The horizontally extending section 52 is provided with an upwardly extending lug 53 and a downwardly extending ear 54. At the position or location of the lower end of the arm and the bracket 45, an opening 55 is made in one of the concave sections 44 of the shaft so that electric cables can be drawn upward through the shaft and into and through the bracket into the arm, and also to provide an entrance for the horizontally extending section 52, The bracket is positioned with its lug 53 resting against the inside of the shaft and its ear 54 abutting the outside of the shaft A shouldered nut 56 is inserted through the opening 55 and is seated (force fitted) inside and against the shaft in a hole 57 slightly below the opening 55. A bolt 58 is inserted through a hole 59 in the ear 53 and is screwed into the shouldered nut 56 to hold the bracket securely in position. To aid in pulling the cables through the bracket and upwardly into the arm, an opening 59A is provided in the horizontal section 52A of the bracket. If desired opening 59A may be covered with a riveted plate.

The upper securing means 24 (see FIGURES 5 and 6), which as heretofore stated as being comprised of an insert 47, saddle 4-8 and bolt 49, is, in more detail, as follows. The hollow insert 47 has a flanged seating portion 60 and a downwardly extending portion 61 which hugs the inside walls of the shaft. To retain the insert in position, a V cut 62 is provided which is the seat of a weld. However, instead of welding, epoxy or other adhesive means can be used to secure the insert to the shaft. The downwardly extending portion 61 of the insert is provided, at each of its concave positions, with an inwardly extending boss 63, having a threaded hole 64 therethrough. The saddle 48 is contoured to fit the arm 23 and rests against it. The bolt 49 extends through holes 65 in the saddle, 66 in the arm and 67 in the shaft and is screwed into the threaded hole 64 in the insert. A locknut 63 is screwed over the end of the bolt 49. The upper part of the arm is thus securely fastened to the top of the shaft.

In the drawings, only one arm is shown; however, an arm could be provided for each of the concave sides of the shaft, and each would be secured as described. In the case of one arm only, a bolt similar to 49, but shorter, is used and no saddle is required. A cover plate 69 is provided for the insert and shaft end and is secured to the insert by screws or bolts 70. If desired, a neoprene or other type washer can be inserted below the cover plate.

The configuration of the shaft, and particularly if a series of spaced openings is provided therein, permits the arm to be adjusted both in height and its relationship to the concave and convex sections of the shaft.

In the variation (see FIGURE 11), a cover plate and directional signal element '71 is shown, which is comprised of a base plate 72, upstanding sides 73, and a top 74. The base plate 72 is similar to cover plate 69 but has an opening therethrough for electric cables. The plates 72 can be integral with the sides 73 and top 74 or they could be separate elements screwed or bolted together. The

sides 73 have windows therein for light rays of various colors to pass through.

In addition to the above directional signal element, there may also be consolidated therewith, or separately mounted, signals to indicate various services attached to the same pole, such as, police call boxes or fire alarm boxes.

The utility box support 25 (see FIGURE 8) is comprised of a fixed jaw element 75 and a movable jaw element 76 which function together with the aid of screws 77 in the fixed jaw and 78 in the movable jaw to retain the support tightly against the shaft 22. The fixed jaw 75 is formed with a flat front face 79 against which the utility box can rest, a rear arcuate face 80 having a contour similar but opposing the contour of the convex section 43 so that it can rest thereagainst, an inwardly extending serrated and arcuate section 81 shaped similar but opposite to the concave section 44 of the shaft, the serrated section being positioned at one end of the sup port 25 and a shouldered seat 82 positioned at the other end of the support 25. The fixed jaw 76 is provided at its front flat face with threaded holes 33 into which screws 84 can be inserted to retain a utility box and with a countersunk threaded hole 85 extending completely through the jaw element. Resting in the hole 85 is screw 77 which, when tightened against the convex section 43 forces the arcuate face 80 away from the convex section 43 and also forces the serrated arcuate section 81 against the concave section, thus clamping the support 25 against the shaft. The movable jaw 76 is formed with a seating portion 86 corresponding to seat 82, an angled portion 87 and an inwardly extending serrated arcuate portion 88 corresponding to size and shape to and extending towards the section 81. The fixed jaw and the movable jaw are provided with a countersunk coaxial hole 89, the fixed jaw portion of the hole being threaded. The screw '78 extends in the hole 89 and as it is tightened against the shaft, forces the seat 82 outwardly against the seating portion 86 and the serrated arcuate portion 58 inwardly against the concave section 44 of the shaft, thus clamping the support 25 against the shaft.

Thus, as heretofore described, we have devised a complete utility standard, which can support any and all devices desired by a community to guide and aid its population. The standard is unique and strong in its construction, in its shaping of the elements and in its method of assembly, and can well withstand the rigors of man and nature to which it will be subjected.

Although we have illustrated and described the preferred embodiment of the invention, it is understood that variations are possible, in the construction of the base, shape of the shaft and arm, the method of securing the shaft and arm together and in the number of arms and other utilities added, which still come within the scope of the invention, and it should therefore be understood that we do not limit ourselves to the precise construction herein disclosed and we reserve the right to all changes and modifications coming within the scope of the invention as defined in any or all of the appended claims.
