Description
1 0~6:Z28 BACKGROUND OF INVEN~ION
As has been pointed out in United States patent 3,911,548, utility poles are subject to damage and deterioration, so it is desirable to provide for convenient replacement thereof.
Hardware connections to distal ends of utility poles represent expensive equipment and highly skilled work-manship, performed sometimes in hazardous condltions.
I Accordingly it is desirable to replace utility poles in such ! a way as to avoid necessity for reworking such hardware and to avoid interruptions of service resulting therefrom.
Convenient and inexpensive means also-have been desirable to alter the elevation and/or alignment of such hardware relative to the earth.
Availability of materials for utility poles and economics relating thereto dictate frequently that a new pole be of a different material (such as wood, steel, aluminum, prestressed or reinforced concrete or resin bonded glass fibers) from that of the existing pole --2-- . ~r ,~p ... . . . . .
~0462Z8 which is being replaced.
BRIEF STATEMENT OF INVENTION
T~e present invention solves the stated problems and other problems of the prior art in a useful, novel,~unobvious and parti-cularly facile way. A movable sleeve connector is presented for use in a method for replacing an existing utility pole, without disturbing hardware mounted thereon. In this method the utility pole comprises a proximal section having a bottom end attached to the earth and a distal section having a hardware thereon. The distal sec-tion (with its hardware intact thereon) is severed from the proximal section of the existing pole. A new pole section is attached to the earth appropriately located and adapted for receiving the distal sec-tion in axial abutting seating thereon to define a joint therebetween.
The distal section then is moved to sit on the new pole section and is engaged to the new pole section by means of a movable sleeve which is annular and engageable about outsides respectively of the new pole section and the distal section. The sleeve is movable between an inoperative position (wherein it is displaced from the joint) and an operative position (wherein it spans the joint from the new pole section to the distal section). The sleeve may be attached to the distal section and to the new pole section by known means such as screws, bolts, grout or the like. The ~oint is sealed by means of a suitable sealant, such as the grout.
The new pole section may have a length substantially the same as the proximal section of the existing utility pole, whereby the hardware will be restored approximately to its original eleva-tion above the earth. Or the new pole section may have a different length from that of the proximal pole section, whereby the elevation .
of the hardware may be changed.
The proximal section may first be severed from the earth so as to leave a stump section protruding from the earth and so as to define a bottom end of the proximal section. Then the proximal sec-tion may be arranged vertically adjacent the stump section with the bottom end of the proximal section on the earth for supporting tem-porarily the distal section.- During the severing of the~distal section from the proximal section and the connecting of the distal section to the new pole section, the distal section is supported independently for example by means of a crane.
The new pole section can be of any otherwise suitable pole material (inc-~uding but not necessarily limited to wood, steel, alumi-num, prestressed or reinforced concrete or resin bonded glass fibers) as can the existing pole (but which in most instances is made of wood).
Preferably the new pole section is of prestressed concrete and formed -hollow so that among other things a connecting line between a distal section and the eartX may be provided therewithin. Hydraulic ~acking is a convenient way of removing the stump section and the hole vacated thereby (with or without augering) is useful for implanting the new pole section therein.
Alternately the new pole section can be erected ad~acent the old pole and, after severing the distal sections (with the hard-ware thereon) from the proximal section of the old pole, the distal section can be mounted on the new pole section. Thereafter the proxi-mal section of the old pole can be removed.
Accordingly one object of this invention is to allow - ~
~046Z2~3 convenient, inexpensive, rapid and safe replacement of damaged or deteriorated utility poles.
Another object of this invention is to allow replacement of utility poles without having to rework hardware thereon and without interruption of service.
Still another objec~ of this invention is to provide for convenient altering of the height and/or alignment of hardware~ on the utility pole.
Still another object of this invention is to accommodate use of a same material or an otherwise suitable different material for new pole sections relative to the material of the existing pole.
Still another ob~ect of this invention is to allow for the proximal section of the existing pole first being se~ered from the earth, so as to leave a stump-section protruding from the earth, and so as to define a bottom end of the proximal section. Then the proximal section may be arranged vertically adjacent the stump sec-tion with the bottom end of the proximal section on the earth for supporting temporarily the distal section.
Still another object of this invention is preferably to use new pole sections of prestressed concrete which may be made hollow and which can accommodate therewithin a connecting line between the distal section and the earth to provide positive ground-ing to the earth.
Still another object of this invention is to provide a movable sleeve connector which is movable between an inoperative position (wherein it is displaced from the joint) and an operative 1046ZZ~3 position (wherein it spans the joint from the new pole section to the distal section). By this expedient the distal section need not be lifted into the sleeve connector in order for the distal sec-tion to sit axially on the new pole section.

DESCRIPTION OF PREFERRED EMBODIMENTS
As taught in United States patent 3,911,,548, and more par-ticularly in Figs. 1-8 thereof taken in sequential order, a method is illustrated for replacing a damaged or deteriorated utility pole having a proximal section attached to the earth and a distal section 14 having hardware 15 mounted thereon and on ,w,,hich util-ity,wires 16 are strung. Replacement of the pole does not require disturbing of the hardware 15 on the distal section 14 and replacement of the pole can be accomplished readily without any iinterruption of service, as described in United States patent 3,911,548.
As can be seen best in Figs. 1-3 of this application, a new pole section 36 has a distal end 37 and has a movable sleeve connector 38 disposed thereabout. The old pole section is severed at 41 and it has a proximal end 42 which is guided to sit onto the distal end 37 of the new pole section 36 in axial abutment thereon -- : .. ' . : ' ~
by a workman 22. This seating is accomplished while the movable sleeve connector 38 is in its inoperative position as shown in Figs. 1 and 2 so that need for lifting of the proximal end 42 is minimized. Thereafter the movable sleeve connector 38 is moved relative to the joint between 37 and 41 to its operative position shown in Fig. 3 wherein it spans the joint 37,41 from the new pole section 36 to the distal section 14 of the existing pole. It should be noted that the disengaged position of the movable sleeve 38 could be up on the distal section 14 whence it could be moved down to its engaged position shown in Fig. 3. The workman 22 uses conventional means for supporting himself as he performs his work.
Depending upon which of the embodiments of the invention is involved, the workman 22 then completes the connection. In the embodiments of Figs. 1-5 the workman inserts lag bolts 52 which pene-trate through openings 51 of the connector sleeve 38. Thereafter he applies grout 56 to the joint.
In the embodiment shown in Figs. 6-8, grooves 57 are shown in the inner margin 58 of the sleeve 38 to,serve to key the grout S6 which bonds the sleeve 38 to the new pole section 36 and which also seals the joint. Recesses 54 key the grout 56 to the lower end 42 of the distal end 14.
In the embodiment shown in Figs. 9 and 10, a new wooden po~e section 36 is connected to an old wooden distal section 14. The sleeve 38 is shown in Fig. 10 in its inoperative position up on the distal section 14 by means of a removable nail 60. An elast~neric band 62 serves-to,close the bottom end of the sleeve 38 against .:
~046ZZ8 leakage of the grout 56. In Fig. 9 this assembly is shown completed.
Weep holes 59 may be predrilled in the sleeve 38 at the elevation of the bottom 41 of the distal pole section 42. Pre-ferably four of such weep holes 59 are predrilled in the sleeve 38.
Stoppers (not shown) are inserted into the holes to prevent grout 5S from leaking therethrough. When the grout 56 is hard~(say in 10 to 15 minutes), the stoppers are removed and bores 61 are drilled into the bottom 42 of the wooden distal pole section. These weep holes allow water, that may intrude through checks in the wood, to drain out and thus deterioration is prevented. Such a weep hole is shown in Fig. 9.
As has been mentioned, various materials for poles and connectors may be interchanged as can be materials used for screwing,~
bolting, grouting, gluing and the like all within the context of thls invention. It will be apparent also to those skilled in manu-facturing~ erecting and repairing of utility poles that wide devia-tions may be made from the shown embodiments, without departing from a main theme of invention delineated in claims which follow.
