32 Clalms, 15 Drawing Figures PATENTEDAPR 41972 3, 653 622 SHEET 1 OF 3 [3 G. 2 MARWON Q. FARMER PATENTEDAPR 41912 3,653 622 SHEET 3 IF 3 QGBA MAEHON Y2. FARMEF? NONLINEAL CROSSARM FOR BRACKETING ELECTRICAL DEVICES BACKGROUND OF THE INVENTION This invention relates generally to means for mounting electrical devices to a utility pole, and more particularly to a nonlineal or arcuate crossarm that is useful for bracketing electrical devices away from the utility pole, but yet arranged within convenient reach of a utility man working upon said pole.

Many apparatuses have been devised for stably supporting electrical devices upon a utility pole. Oftentimes, as in the past, the crossarm used for this purpose was generally a straight piece of lumber or the like which simply attached at its midpoint to the utility pole, with various electrical devices being mounted upon its lateral extensions, this type of a prior art device being by way of example disclosed in my previous U.S. Pat. No. 3,468,57 1. Other prior art devices, such as the capacitor assembly as disclosed in U.S. Pat. No. 3,254,270,

recognized that some convenience was achieved through the use of a frame structure having angularly extending end portions, but this capacitor mountingdevice did not include the use of brackets that may alternately mount other types of electrical equipment such as arresters, pothead's, or the like, at various angular relationships to the vertical. In my previous U.S. Pat. No. 3,497,171, it was disclosed that various multiwinged fixtures may be utilized for attaching electrical devices of the aforementioned category to a utility pole, but this device did not incorporate the convenience and ease of mounting of the arcuate crossarm, and its various brackets, as disclosed in this invention, but rather, was more concerned with the disposition of the electrical devices at various radially disposed distances surrounding the utility pole.

It is the principal object of this invention to provide an arcuate crossarm that partially surrounds the utility pole but yet displaces electrical devices a sufficient distance from said pole through the use of various brackets which include mounting surfaces that may be arranged vertically or at an angle with respect to the vertical.

It is another object of this invention to provide a nonlineal crossarm including multiple brackets that are useful for mounting a plurality or cluster of hook-stick switches, potheads, arresters, or related electrical devices upon a utility ole. p It is a further object of this invention to provide an arcuate crossarm being a unitary structure that is useful for mounting a plurality of heavy duty, three-phase electrical equipment upon the utility pole.

Another object of this invention is to provide a bracket for vertically mounting electrical devices upon an arcuate crossarm, which bracket may be easily inverted by a worker, even while ascended upon the utility pole, so as to provide for a forward inclination and convenient disposition in the mounting of one or more electrical devices upon said utility pole.

An additional object is to provide an adjustable bracket which may be directly anchored to a utility pole.

It is still another object of this invention to furnish a unitary arcuate crossarm disposed for connecting with spatially arranged brackets formed from either angles, multi-flanged angles or tee angles, that may conveniently support electrical devices either directly or through the use of various pads or hangers.

Other objects will become more apparent to those skilled in the art in the light of the following description and accompanying drawings.

SUMMARY OF THE INVENTION This invention incorporates the use of an angled crossarm, preferably being arcuate, partially encircling the utility pole, which crossarm is anchored proximate its midpoint for aesthetic and/or balancing purposes directly to the utility pole. To further stabilize the mounting of the crossarm upon the utility pole, a pair of trusses extend from the pole to approximately the quarter points of said crossarm, so that the mounting of heavy duty equipment such as arresters or disconnect switches to a bracket at one end of the crossarm will yet be stably supported upon the utility pole.

The connecting of this arcuate crossarm to the utility pole is beneficial from the standpoint of leaving the backside of said pole substantially vacant, so that the utility man working upon the pole will have sufficient clearance for movement, but yet due to the arcuateness of the crossarms, and particularly locating the electrical devices along a curve almost laterally of the utility pole, the workmen will yet be able to have sufi'icient reach for installation or manipulation of electrical devices mounted all along the crossarm to its various brackets. As previously stated, other mounting devices either incorporate just a straight crossarm, which makes it difficult for a utility man to have access to the electrical devices mounted especially at its ends, or the crossarms are bent or disposed almost entirely around the utility pole, which does not leave sufficient clearance for the utility man to maneuver along the backside of the pole, while placing the electrical devices mounting to the front of the crossarm at a distance beyond his reach due to his confinement.

The various brackets incorporated and used in combination with this arcuate crossarm all provide a mounting surface of a variety of sizes so as to accommodate a particular sized electrical device, such as a small arrester, or a heavy duty threephase arrester, cutout or hook-stick switch of the type used with three-phase equipment and being of either the intermediate or distribution type. Obviously, the latter type equipment can be manufactured of substantial size, having some significant weight, and therefore, the configuration of the brackets utilized in combination with the arcuate crossarm must be structurally sound so as to support the heavier devicesstably upon the utility pole, free from any damage that might otherwise occur during adverse weather conditions.

Generally the brackets of this invention include a mounting surface having inturned ends which connect upon a support means that secures directly to the crossarm. The downward inturned edge of the mounting surface is braced either to the opposite end of the support means, or it may be braced directly to the anchor means as is the case with the bracket connecting proximate the midpoint of said crossarm. When manufactured in this manner, the mounting surface may be constructed so that when properly secured its surface will be vertically arranged, but when inverted, the connection of its various inturned edges will provide for an inclination in said mounting surface. Under certain conditions it is desirable that various electrical devices such as potheads, arresters, or hook-stick switches have some inclination angled away from both the utility pole and its crossarm for purposes of clearance and easier wiring of the connecting electrical lines, to provide proper spacing between a cluster of such devices, or more particularly with regard to disconnect switches, to permit easy opening and closing of such a switch by a lineman. Hence, the spatial attachment of these brackets to an arcuate crossarm is such that each bracket may provide support for a cluster of electrical devices, which are conveniently displaced away from the utility pole, but yet are each within convenient reach of the utility man who has located himself to the backside of the pole for purposes of working upon or exchanging particular of these electrical devices.

When it is desired to provide a less clustered attachment of various electrical devices to the arcuate crossarm, a pad, having some angularity to it if desired, make connect directly to the support means in place of the usual mounting surface as previously described, and said pad is conveniently bifurcated so as to provide for attachment of, for example, a flange style pothead to each bracket. Furthermore, various combinations of structural angles, such as multi-flanged angles or tee angles, may be connected spatially upon the arcuate crossarm, providing convenient mounting surfaces that may support hangers or the like for mounting of other type electrical devices such as cutout-arrester units. Obviously, a combination of various electrical devices may be used upon a utility pole, and cooperate with each other, to achieve a particular result. Thus, the combination of angles, or structural tees, as herein defined, when formed into a bracket, are conveniently disposed for providing a mounting of particular electrical devices in combination to produce a single function. Hence, a series of three intermediate arresters and three disconnect switches may be mounted upon the various brackets defined herein, with the disconnect switches being mounted to the inclined mounting surface of the brackets, and the arrester being mounted upon each support means to provide a paired group of devices to achieve a particular electrical function. The various angles, or structural tees, may be spatially connected upon the arcuate crossarm, with their flanges being either longitudinally extended in alignment with the curve of the crossarm, or even project vertically to provide a mounting surface for connection of one or more electrical devices, as previously described. The flanges of the structural tees may be arranged in abutting relationship upon the crossarm so as to provide a full length of mounting surface for connection of, for example, the base of a heavy duty hanger which may be useful for supporting a cutout of significant size.

This arrangement of various brackets as used upon this arcuate crossarm, and the usefulness of its various combination of brackets that may be formed from various structural angles or tees will become more clear when reviewing the preferred embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, in FIG. 1, reference characteristic A generally depicts one embodiment of this electrical equipment mount, with reference numeral 1 indicating a nonlineal crossarm, being arcuate as herein shown, which partially encircles the utility pole P, and connects with the same through the agency of an anchor means 2, with a pair of trusses 3 and 4 further stabilizing this support. A series of brackets 5, 6 and 7 connect to approximately either end and at the midpoint of said arcuate crossarm, and are disposed for holding a variety of electrical devices (not shown) properly displaced away from the pole, but yet within easy reach of the utility man who may be working upon said pole.

By referring to FIGS. 2 through 4, it can be seen that the arcuate crossarm 1 may be composed of any form of structural material, but preferably is formed of an extruded aluminum alloy, and being of the tube, channel or box channel design in crosssection. As here shown, the trusses 3 and 4 connect at approximately the quarter points of said arcuate crossarm, being fastened thereto by means of the series of fasteners 8 and 9, with the other ends of said trusses being connected approximate the sides of said pole. In this manner, it can be readily seen, especially in FIG. 2, that there is available clearance along the back side of the utility pole for maneuvering of the utility worker, giving him approximately climbing space, but at the same time, due to the arcuateness of the crossarm, the braces and mounted electrical devices will be within easy reach for handling by said worker.

The anchor means 2 of this invention comprises a substantially rectangular shaped structure that includes an vend member 10 which is disposed for fastening directly to the side of the crossarm by means of a series of fasteners 11, with a pair of integral legs 12 extending rearwardly therefrom, with each terminating in a substantially C-shaped foot 13 thatis disposed for mating engagement with the distal ends 14 of the rib members 15 that are integrally formed with the curved spine 16, that anchors to the utility pole. A series of properly placed thru-bolts on the pole will accomplish this anchoring. A crossbrace 17, held by the fasteners 18, further stabilizes the structure of this anchor means. As shown, a pair of grounding lugs 19, each being secured to a leg 12 are conveniently disposed for providing grounding of the crossarm and electrical devices if necessary.

The end brackets 5 and 7 of this invention are substantially identical in construction, with each bracket including a support means 20, herein shown as a length of structural angle, with the upward portion of a mounting surface 21' being fastened to one end of said support means, while the bottom portion of said mounting surface connects with a brace 22 that is fastened to the other end of said support means. It is to be noted that the edges 23 and 24 of both the upward and lower portions respectively of each mounting surface 21 are inwardly or inturned bent so that they may be each disposed in overlying relationship with respect to the parts to which they attach, here being the ends of the support means 20 and the brace 22. Likewise, the ends of each brace are accordingly bent to that angle which provides for their snug and flush mounting with the parts to which they connect, here being the back end of the support means, and the inwardly bent edge 24 of the downward portion of each mounting surface. It is to be noted that the vertically disposed flange 25 of each support means or angle 20 is formed having inclined edges at each of their lateral ends 26 and 27, so as to provide clearance for the attachment of both the mounting surface 21 and brace 22 of each bracket thereto.

The bracket 6 that connects approximately to the midpoint of the arcuate crossarm is structurally formed somewhat similar to the brackets 5 and 7, wherein this bracket includes a mounting surface 28 having an inwardly or inturned bent edge 29 in its upward portion being fastened to a support means or plate 30, which plate secures by means of a series of fasteners 31 to the upper edge of said arcuate crossarm. A pair of supplemental fasteners 32, see FIG. 2, are structurally secured to the plate 30, and provide further support for attachment of additional electrical devices, such as arresters, or the like. This allows for the convenient clustering of electrical devices around each bracket. The downward portion of the mounting surface 28 is formed having an inwardly or inturned bent edge 33 which secures by means of a fastener as shown to a brace 34, which brace at its back end connects by means of a fastener as shown to the crossbrace 17 that is structurally secured within the anchor means 2. Thus, the mounting surface 28 is structurally supported within this electrical equipment mount, and is useful for supporting electrical devices of sufficient weight. It is also likely that a single bracket 6 may be anchored to a pole by having its plate 30 connecting to the anchor means or be retained thereto by means of an angle or the like.

Each of the mounting surfaces 21 and 28 of the various brackets are herein shown to be relatively flat, and vertically disposed, and through their series of fasteners or attaching areas 35, they readily support the various electrical devices such as hook-stick switches, potheads, fuse cutouts, or the like. In addition, various other supplemental brackets, as at 36, or supplemental fasteners, as at 37, are provided throughout the mount to allow for convenient clustering of electrical devices.

Upon viewing FIG. 5, it can be seen that each bracket of this invention, as previously described, can be manipulated so that its mounting surface may be disposed at an angle with respect to the vertical. This is achieved through an inverting of a mounting surface as previously described and as shown at 38, so that the inturned edge of its normally downward portion, now at 39, which is bent at an acute angle, is now disposed and becomes the upward portion of the mounting surface, and secures to one end of the support means 40, while the inturned edge of the normally upward portion, as at 41, of said mounting surface now becomes the downward portion and connects with one end of the brace 42. As previously disclosed, the

other end of the brace 42 attaches directly to the opposite end of the support means or angle 40. Hence, under this manipulation, the mounting surface of each bracket may be angularly disposed, which in this case is arranged at approximately a angle with the vertical, so that various electrical devices, such as a disconnect switch, may be mounted thereto and disposed at that angle which permits its easy handling, such as in opening or closing ofthe switch by a lineman.

F I65. 6 and 6A disclose the arcuate crossarm l which is secured to the utility pole by means of an anchor means 2, but which incorporates a variation in the form of brackets utilized at approximately each end'and at the midpoint of said crossarm. The end connecting brackets 43 are similar to the support means previously described and used in conjunction with the brackets 5 and 7, and comprise a length of angle, each connecting approximately at its center to the end of the crossarm. When disposed in this manner, either the horizontally disposed flange 44, or the vertically disposed flange 45, of each bracket provide a mounting surface to which electrical devices may connect, as through the medium of the fasteners, as for example shown at 46. The central connecting bracket 47 connects approximately at the midpoint of the front portion of the crossarm. This bracket also comprises an angular member, being more specifically described as a multi-flanged angle, which has a pair of upper and lower spaced apart flanges 48 and 49 connecting with the crossarm, with another of its flanges, as at 50, projecting outwardly and which may support electrical devices through the agency of fasteners, such as at '5]. Obviously other fasteners may attach to the bracket to support electrical devices. The web portion 52 0f the tee is maintained flush with the outer edge of the crossarm to further stabilize the mounting of any electrical devices upon this bracket.

By referring to FIGS. 6B through 6D, there is disclosed a pad 53 which may be mounted upon the horizontally disposed flanges of the brackets 43 and 47, by connection of the various fasteners, as at 54, through its apertures 55. This pad includes a flat portion 56 for attachment to the flanges, as aforesaid, and also has an integrally and angularly bent portion 57, which is bifurcated as at 58, so as to be readily adaptable for mounting, for example, flange style potheads. This pad desirably is formed for extra rigidity so as to readily support the mounting of heavy duty electrical devices thereto and upon the crossarm.

FIGS. 7 and 7A disclose a further modification in the brackets utilized in conjunction with the arcuate crossarm l, as anchored to the utility pole, and these brackets also connect proximate the ends and to the midpoint of said crossarm. Each of the end connecting brackets 59, and also the central connecting bracket 60, are similar in configuration to the bracket 47 previously described. These angles have multiple flanges, with the overlying flanges 61 and 62 of each bracket attaching to the crossarm, with the web portions 63 extending downwardly for flush mounting against the proximate edge and ends of the crossarm. Each of the end attaching brackets 59 have a flange 64 that projects outwardly in a similar longitudinal alignment approximating the curve of the crossarm. Each flange 64 is provided with a fastener 65 which is useful for retaining one or more electrical devices. The bracket 60 securing approximately at the midpoint of the crossarm 1 also has a flange 66 that projects outwardly for mounting of an electrical device thereupon.

FIGS. 8 and 8A show a further modification in the form of brackets utilized in conjunction with the crossarm 1 as anchored to a utility pole. Each of these brackets 67 also connect approximately to the ends and at the midpoint of the crossarm, and each comprises a pair of angle members 68 and 69, formed as structural tees, whose web portions 70 are secured by means of fasteners, as at 71, to the upper and lower edges of said crossarm, while one flange 72 of each tee projects wither upwardly or downwardly and having surfaces for mounting of electrical devices by means of the fasteners 73 as shown, while the other flanges 74 are disposed in abutting relationship mounted flush over the ends or front edge of said crossarm.

FIG. 8B discloses a form of hanger 75 which includes a base 76 which mounts to the type of brackets 67 disclosed in F IG. 8A, with said base including a shank 77 that extends angularly therefrom and includes a clamp 78 upon its opposite end to which an electrical device, such as the cutout C as shown, may attach. An arrester T, of this cutout-arrester unit, may be clamped to the upper edge of flange 72, to complete this cluster of electrical devices. By providing for an angular disposition of a cutout in this manner, a utility man may easily manipulate the cutout as desired, since its angularity and disposition makes it readily and openly exposed for handling. Furthermore, since the base portion of this hanger extends substantially the full height of the flanges 72 of each bracket, said hanger is very stably support upon the crossarm.

Various and numerous modifications and variations in the construction of the nonlineal crossarm for bracketing electrical devices as shown in this invention, within the scope of the appended claims, will occur to those skilled in the art in the light of the foregoing disclosure.
