Abstract
ABSTRACT OF THE DISCLOSURE
The bracket anchors a hydro pole or a telephone pole vertically on rocky ground or on ground beneath which are sewer pipes or electrical conduits. The bracket con-sists of a number of pole-mounts each having a base which rests on the ground and an upright which contacts the pole.
The pole-mounts are spaced about the circumference of the pole and are clamped to the pole by means of bands inter-connected by links. The length of each link is adjustable to fit poles of various sizes.
A leg extends downwardly from the pole-mount into a hole in the ground. The leg consists of a sleeve to which a number of wedges are connected. A bolt extends downwardly from the base of the pole-mount into the sleeve and mates threadably with a camming plug. Rotation of the bolt causes the plug to move upwardly into contact with the wedges and to force them outward into contact with the inside wall of the hole with resulting anchoring of the leg in the hole.

BACKGROUND OF rr~lE INVENTION
This invention relates to brackets for anchoring poles such as hydro or telephone poles upright on the ground ancl more particularly to brackets suitable for an-choring poles in rocky, rugged terrain where the surfaces on which the poles rest need not be horizontal or on ground beneath which sewage or electrical conduits are located where the location of the anchoring means for the brackets is extremely restricted I
Various brackets are known for maintaining poles vertical on rocky ground. rrhe brackets are connected to anchor bolts which are secured in holes drilled in the ground adjacent to where the pole is to stand. U~S. patent No. 3,514,911 to Preradovich and U.S. patent No. 4,218.858 .2~ 3 to Legler both referred to above, describe brackets suit-able for -this purpose.
~ shortcoming of known brackets such as those described in the patents referred to above is that they are generally unsuitable where the holes in which the anchor bolts are secured are inaccurately located. Should ~or example those holes not extend exactly vertically downward it is not possible to tighten the anchor bolts in the holes except with the greatest of diE~iculty. Similarly if the holes are not spaced apart from the poles an exact pre-determined distance, the brackets cannot be secured in such a way as to minimize lateral movement of the pole after the pole is attached to it.
The reason why the holes must be accurately loc-ated is because the brackets are held in position by elong-ated bolts which extend downwardly through sleeves in the brackets and into the holes. The bolts must be rotated in order to fasten them in the holes. Should -the holes not be accurately located the bolts must be bent to fit into those holes. The greater the amount o~ bend the more difficult it is to rotate the bolts.In fact it is altogether impossible to rotate the bolts should the amount of bend be too great.
SUMMARY OF TilE INVE'NTION
It is an object o~ this invention to provide a ~Z~2~3 bracket which is suitable for supporting a pole in the most rugged, rocky country where the unevenness and the nature of the terrain makes it difficult if not impossible to drill holes which are exactly vertical or which are accurately placed in relation to the intended location of the pole.
Moreover the bracket may be used to support a pole where the ground beneath it is occupied by a sewage .system or by underground cables.
It is another object of this invention to provide brackets which will support poles on ground which is not level. Moreover wide latitude in the location and the or-ientation of the holes is possible so that the holes can be located primarily where the anchor bolts will be best se cured and only secondarily where the pole is to stand.
These and other objects are accomplished by a bracket for anchoring a pole vertically on a rock like support surface comprising: a plurality of pole-mounts hav-ing a base for resting on the support surface and a h~
~2~2~33 vertically upwardly extending upright which contacts the pole; clam~ing means for clamping the pole-mount to the pole; a leg which extends downwardly from the pole-mount for insertion into a hole which extends downwardly from the support surEace, the leg including a sleeve, an inner member and expandible means, the sleeve having an upper end connectable to the base and extending downwardly therefrom, the inner me~rnber being rnovable within and relative to the sleeve, and when so moved causing lateral expansion of the expandible means with resulting anchoring of the leg in the hole.

DESCRIPTION OF T~IE PREFERRED EMBODIMENl' With reference to Figure 1, the bracket of the invention, generally 20, is shown in conjunction with a hydro or telephone pole 22. The bracket includes a pole-mount 24 and a pair of spaced clamps 26.
'rhe pole-mount is made up of a base 30 and an upright 32. The base is vertically extending and has an under surface 34 which rests on the ground or other support surface for the pole. The upright has a yenerally ~ shaped cross section and is made up of a central "eb 36 which contacts the pole and two spaced flanges 38 which extend at yenerally riyht anyles from the -two side edges of the web.
A number of vertically spaced reinforcing ribs 40 extend between the flanyes.
With reference to Figure 1, each clamp 26 is made tJp of a pair of bands 42ar b ~7hich are attached to the exterior flanye walls ancl which extend circumferentially around the pole. An aperture is formed in each band and a link 44 extends between the bands and its ends pass throuyi the apertures.
The bands may be attached to the pole-mounts by welding or they may be bolted to them. Alternatively as illustrated in Figures 2, 3 and 9, the bands 43 pass throuyh slots 48, 49 in the two flanges of the mount and extencJ outwardly from opposite sides of the same mount.
Where the bands are so formed, they are free to slide horizontally in the slots in the pole-mounts.
~1ith further reference to Fiyures 2 and 9, link 44 is in the form of a bent rod having a threaded enc] portion 44a. The opposite end 44b has a foryed offset head or hook 44b which is removably accommodated in a key-hole 45 formec1 in hand 43a. The threadecl end o~ the link i5 inserted in ~Z~3~33 the aperture formed in band 43b. A nut 50a prevents the threaded end from beiny removed from the band. The key-hole shape ensures that the rod will not be disconnected from the band when assembled as illustrated in Figuré 2.
When the links are so assembled, the links, the bands and the pole-mounts together extend around the entire cir-cumference oE the pole. The assembly restrains the pole from movement and pole is thus anchored in position. There is no need to use lag bolts to prevent the pole-mounts from turn-ing with respect to the pole.
With reference to Figures 4 and 5, the pole~mount isshown in conjunction with the components which together form a leg for anchoring the pole-mount to the ground. The leg, generally 50, is made up of a sleeve 52, a camming plug 54 and an inner member or bolt, generally 56. A pair of hor-izontally spaced paralled slots 58 are formed on the under surface 34 of the pole-mount. The slots commence at the wall 32a of the upright 32 which faces the pole and extend at generally right angles to that wall. The slots terminate at a stop 60. The slots removably accommodate opposite edges of a plate 62 which is attached to the upper wall of sleeve 52.
rrhe plate is loosely received in the slots so that, as illustrated in Figure 3, the sleeve is free for limited pivoting or rocking Erom side to side or forward or back while remaining within the slots.
Connected to the lower end of the sleeve by, for example, welding are circumferentially arranged segments , 8 ~', .,~
9~3 66, the outer diameter of which being the same as that of the sleeve to which the segments are attached. A ~pace or slot 67 is between adjacent segments. As illus-trated in Figures 6 and 7, each segment is shaped in the form of an wedge which opens upwardly and inwardly i.e. the wedge is thinnest at its lower edge 66a and thickens upwar~ly. Those .sec;ments constitute expandible means Eor engaying the wall of the hole in which the sleeve is inserted. The way in which they do so is described below.
Camminy plug 5~ serves to urge the segments 66 between the slots outwardly or to e%pand. The plug has a frusto-conical outer wall of the same slope as that of the inner wall of the segments. A number of ribs 68 are Eormed on its outer wall. The number o:E ribs is the same as the number of slots 67. The width oE the ribs is slightly less than the width of the slots and the ribs are so arranged that each will fit into a separate slot. ~s a result the plug can be positioned concentrically within the sleeve.
The outer diameter of the conical wall of the pluy at its upper wall 70 is slightly greater than the inside diameter of the segments. The conical wall of the plug enlarges downwardly and, at its lower wall, its outer diameter exceeds the inside diameter of the segments. The outer diameter oE the ribs is the same ~rom the upper to

A number of vertically spaced reinforcing ribs 40 extend between the flanyes.
With reference to Figure 1, each clamp 26 is made tJp of a pair of bands 42ar b ~7hich are attached to the exterior flanye walls ancl which extend circumferentially around the pole. An aperture is formed in each band and a link 44 extends between the bands and its ends pass throuyi the apertures.

Where the bands are so formed, they are free to slide horizontally in the slots in the pole-mounts.
~1ith further reference to Fiyures 2 and 9, link 44 is in the form of a bent rod having a threaded enc] portion 44a. The opposite end 44b has a foryed offset head or hook 44b which is removably accommodated in a key-hole 45 formec1 in hand 43a. The threadecl end o~ the link i5 inserted in ~Z~3~33 the aperture formed in band 43b. A nut 50a prevents the threaded end from beiny removed from the band. The key-hole shape ensures that the rod will not be disconnected from the band when assembled as illustrated in Figuré 2.
When the links are so assembled, the links, the bands and the pole-mounts together extend around the entire cir-cumference oE the pole. The assembly restrains the pole from movement and pole is thus anchored in position. There is no need to use lag bolts to prevent the pole-mounts from turn-ing with respect to the pole.
With reference to Figures 4 and 5, the pole~mount isshown in conjunction with the components which together form a leg for anchoring the pole-mount to the ground. The leg, generally 50, is made up of a sleeve 52, a camming plug 54 and an inner member or bolt, generally 56. A pair of hor-izontally spaced paralled slots 58 are formed on the under surface 34 of the pole-mount. The slots commence at the wall 32a of the upright 32 which faces the pole and extend at generally right angles to that wall. The slots terminate at a stop 60. The slots removably accommodate opposite edges of a plate 62 which is attached to the upper wall of sleeve 52.
rrhe plate is loosely received in the slots so that, as illustrated in Figure 3, the sleeve is free for limited pivoting or rocking Erom side to side or forward or back while remaining within the slots.
Connected to the lower end of the sleeve by, for example, welding are circumferentially arranged segments , 8 ~', .,~
9~3 66, the outer diameter of which being the same as that of the sleeve to which the segments are attached. A ~pace or slot 67 is between adjacent segments. As illus-trated in Figures 6 and 7, each segment is shaped in the form of an wedge which opens upwardly and inwardly i.e. the wedge is thinnest at its lower edge 66a and thickens upwar~ly. Those .sec;ments constitute expandible means Eor engaying the wall of the hole in which the sleeve is inserted. The way in which they do so is described below.
Camminy plug 5~ serves to urge the segments 66 between the slots outwardly or to e%pand. The plug has a frusto-conical outer wall of the same slope as that of the inner wall of the segments. A number of ribs 68 are Eormed on its outer wall. The number o:E ribs is the same as the number of slots 67. The width oE the ribs is slightly less than the width of the slots and the ribs are so arranged that each will fit into a separate slot. ~s a result the plug can be positioned concentrically within the sleeve.
The outer diameter of the conical wall of the pluy at its upper wall 70 is slightly greater than the inside diameter of the segments. The conical wall of the plug enlarges downwardly and, at its lower wall, its outer diameter exceeds the inside diameter of the segments. The outer diameter oE the ribs is the same ~rom the upper to
2~33 the lower walls oE the plug. ~ threaded bore 72 extends along the longitudinal axis of the plug.
Bolt 56 has a shank 73 which removably passes through an enlarged aperture 74 in base 30 and downwardly through the sleeve. As illustrated in Figure 5, head 76 of the bolt has an outer diameter which is larger than the width of the aperture so that it cannot pass through the aperture.
With reEerence to Figure 6 and 7, the lower por-tion of ~he shank is threaded at 78 and those threads matethreadably with the threads in the bore of pl~g 54. The ribs 68 of the plug are in the slots between segments 66 and will prevent the plug from rotating as the bolt is rotated. Rotation of the bolt will accordingly cause the plug to rise on the shank of the bolt Erom the position shown in Figure 6 to the position shown in Figure 7t In -the latter figure, the conical wall of the plug which contacts the inside wall of the segments causes them to move radial-ly outwardly of the longitudinal axis 80-80 of -the sleeve and into contact with the wall 82 oE the hole in which the sleeve is located.
Further upward movement of the plug causes the segments to more firmly contact the inside wall Oe the hole and to cause the sleeve to become rnore and more so]idLy anchored in the hole.
With reference to Figure 8, bolt 56 is rotated by oscillation o-f handle or ratchet 82 which is removably connected to the upper end of a socket extension 8A. A
socket 86 at the lower end enyages the head oE the bolt and causes it to rotate when the handle is oscillated.
~rhe soc~et extension is prevented From rocking or swaying when it is being rotated by means of pair of arms 88 which apply an inward pressure against diameterically opposite sides of an enlarged portion of the socket exten-sion. The ends of the arms remote from the socket extension are attached to tabs 90 which fit snugly into the space between the ~ands 42 and the pole. The tabs can be with-drawn from the space and the socket and socket extension are removed after the bolt has been tightened sufficiently to anchor the sleeve in the hole.
rA7ith reference to Figure 10, a template, generally 92, facilitates the location of the holes to be drilled where the pole is to be anchored by means of three brack-ets. ~he template consists of three sleeves 94, 96 and 98.
S]eeve 94 consiste of a lower segment 94a oE outside dia~
meter slightly less than the diarneter oE the hole which is to be drilled and an upper segrnent 9~b of greater diameter.
The other two sleeves 96, 98 have uniEorm cross-sections z9~33 thLo~3~lolt t;l~?ir l~ni3t~ls.
~ n expandible ari~ lO0 extends between sleeves 94 and 96 and a like arm 102 extends between sleeves 94 and 98. As illustrated the loncJituclinal axes oE both ar~s are oriented at right angles to ti7e Longit~(lina~ axes 0~ the sleeves and the angle between the axes oE the arms is approxi~ncltely 60 de~rees.
A s~ud 10~ extends inward Ero(n each .qleeve. The length oE tile stud determines the distance f)f the hole ~rom the pole in tne manner desc~ihecl below.
Arm 100 consists of a hollow rectangular first sectioll lOOa which is attached to sleeve 94. ~ second rectangular section lOOb is connected to sleeve 96 and is slidingly received in the hollow interior of section lOOa.
sy .neans of set screw 106 the two sections can be locked together in any desired position~ The position of sleeve 94 relative to sleeve 96 can accordingly be increased or decreased~
The construction of arm 102 is the same and its length can likewise be a-]justed by ineans of set screw 108.
Figures 11 and 12 illustrate the manner in which the template can be used to locate the position of the holes which In~st be drilled in the ground. First a hole is drilled beside the place where the pole is to stand. Sec-.Z~ 33 ondly while the pole is resting horizontally on the ground the template is placed beside the lower end of the pole such that the pole is between its arms as illustrated in those Fic;ures. Thirdly the two set screws are loosened to allow t'ne length of the arms to be adjusted until the studs lO~band lO~ccontact the outside wall of thepoleportion.
~he template is then separated from the pole by moving it to the end of the pole.
The lower segment of sleeve 94 is then insertecl into the hole that was drillecl in the ground. ~'he upper secJment which has an outside diameter greater than the cross-section of the hole will remain on top of the hole.
Two more holes are then drilled uSincJ the other two sleeves as guides. The three holes will be correctly located ac-cording to the size of the pole.
In Figure 12 the pole has a smaller outside dia-meter than the pole illustrated in Figure 11 and the length of arms lO0 and 102 are correspondingly shorter to reflect the smaller diameter.
The holes which are drilled must have a cross-sectional area slightly greater than that of the outside wall of the sleeves so that the sleeves can be easily inserted into the holes~ After the holes have been drilled and before the pole is moved into position Eor anchoring, ~?J~Z~33 one sleeve is attached to a pole-mount by inserting its plate 62 into slots 58 so that the sleeve and mount are connected as illustrated in Figure 5.
~ olt 56 is then inserted downwardly through the aperture 74 of the pole-mount and through the central bore of the sleeve and while the sleeve and the mount are out-slde the hole the plug is turned onto the lower encl of the bolt anc] the bo]t is rotated until the upper ends o~ its ribs are just ~,~ithin slots 6~ of the sleeve. The assembly is then inserted into the hole.
The pole is then raised by some suitable means such as hy a mobile crane and is positioned upright beside the pole-mount. The other two pole-mounts are then con-nected to the legs in the manner described above and are placed in position adjacent to the other two holes. The three mounts must be at the same level and shims may be used foc this purpose. The three pole-mounts are then interconnected by means of clamp 26.
The three mounts rnay then be anchored by tighten-ing the bolts connected to each by means oE the socketassembly 82, 84 and 86 with resulting stabilization and anchoring oE the pole in an upriqht position. Should the wall of the holes crumble, the mounts will not he satis-Eactorily anchored. In such case, the mounts must be moved ~9 2~
to a new location where they can be properly anchored.
Once the pole-mounts are properly anchored, grout-ing oE the holes is not necessary since the strenqth of the installation depends only on the jamming action of the segments in the holes.
With reEerence to ~iyure 3, it will be observed that the ground on which the pole is moun~ed is not horiz ontal and the hole in which one leg is located is not vertical. All that is required is that the pole-mounts be anchored in the ground by means of legs 50. When the pole is to be mounted on uneven ground the pole-mounts should be shimmed up with rocks so that the bands of the clamps are horizontal. After the pole is clamped to the assembly, the shims may be removed since the pole is supported by the pole-mounts and legs and not by the weight of the pole on the ground. BackEilling or grouting of the holes in which the legs are located are not necessary.
Since the bracket of the invention does not re-quire any grout or cement to maintain it in position, the bracket may be removed after use. To do so, the pole must be held upright by means of, for example, a crane and the three bolts must be loosened. As the bolts are loosened, the bolt head will move upward from the base of the brack-et. ~ sharp blow to the bolt head ~ill move the bolt down-21~;~93~
ward and release the camming plug from the segmen-ts 66 oE
the sleeve. The entire assembly can then be lifted easily from the hole.
The bracket Oe the invention is desiyned to allow for variations in the size of the outer diameter of the pole. As illustrated in Fiyuee 4, aperture 74 in the base oE the pole-rnolJnt is elongated and allows the pole-rnount to be moved hackward and Eorward to accommodate poles oE
larger or srnaller diameter. In addition by reason of the elongated apertures, the leg to which the pole i, attached need not ~e vertical. The aperture allows the bolt whicl-passes through it to be oriented in different directions.
Figure 3 illustrates this.
The clamp can likewise accommodate poles of diEf-erent diameters. As illustrated in Figure 2, the effective length of each link can be changed by means of the nut which is turned on its threaded end portion. By advancing the nut toward the hook, for example, the effective length of the link is shortened. When the link is in the assembly illustrated in Figure 2, the area bo~nded by the links and bands is red~ced as the efEective length oE the links is reduced.Conversely the area is increased so that a pole Oe larger diameter can be accornmodated simply by increasing the effective lenyth of each link in the assembly.
Z~3~3 In the event that tlle links cannot be lengthened sufficiently to accommodate a large pole all that is neces-sary is to substitute longer links for the e~isting links in the assembly of links and bands.
It will be understood from the foregoing that the pole-mount oE the invention will accommodate all sizes of poles normally encountered in practice as will the bands of the clamp. The only component that may not accommodate poles oE all .sizes is the link. For that reason it is advisable on a job site to stock links of different sizes.
~lowever because of the adjustability of the links very few different sizes of links are necessary.
In general it is preferable for the pole-mounts which support a pole to be about 120 degrees apart. ~owever this is not essential. Where the terrain makes this impos-sible the design of the clamps is such that the spacing between adjacent pole-mounts can be adjusted according to the spacing between pole-mounts. It is not necessary that the effective length of the linlcs in an assembly of links and bands be the same.
Preferably the pole-mount and the camming plug are cast in malleable iron and the clamps and the remaining components of the legs are formed of galvanized steel.
It will be understood of course that modifications can be made in ~he preferred embodiment described herein wit'nout departing from the scope and p~rview of the invent-ion as defined in the appended claims.
.. . .. . . ... . .. .
Bolt 56 has a shank 73 which removably passes through an enlarged aperture 74 in base 30 and downwardly through the sleeve. As illustrated in Figure 5, head 76 of the bolt has an outer diameter which is larger than the width of the aperture so that it cannot pass through the aperture.
With reEerence to Figure 6 and 7, the lower por-tion of ~he shank is threaded at 78 and those threads matethreadably with the threads in the bore of pl~g 54. The ribs 68 of the plug are in the slots between segments 66 and will prevent the plug from rotating as the bolt is rotated. Rotation of the bolt will accordingly cause the plug to rise on the shank of the bolt Erom the position shown in Figure 6 to the position shown in Figure 7t In -the latter figure, the conical wall of the plug which contacts the inside wall of the segments causes them to move radial-ly outwardly of the longitudinal axis 80-80 of -the sleeve and into contact with the wall 82 oE the hole in which the sleeve is located.
Further upward movement of the plug causes the segments to more firmly contact the inside wall Oe the hole and to cause the sleeve to become rnore and more so]idLy anchored in the hole.
With reference to Figure 8, bolt 56 is rotated by oscillation o-f handle or ratchet 82 which is removably connected to the upper end of a socket extension 8A. A
socket 86 at the lower end enyages the head oE the bolt and causes it to rotate when the handle is oscillated.
~rhe soc~et extension is prevented From rocking or swaying when it is being rotated by means of pair of arms 88 which apply an inward pressure against diameterically opposite sides of an enlarged portion of the socket exten-sion. The ends of the arms remote from the socket extension are attached to tabs 90 which fit snugly into the space between the ~ands 42 and the pole. The tabs can be with-drawn from the space and the socket and socket extension are removed after the bolt has been tightened sufficiently to anchor the sleeve in the hole.
rA7ith reference to Figure 10, a template, generally 92, facilitates the location of the holes to be drilled where the pole is to be anchored by means of three brack-ets. ~he template consists of three sleeves 94, 96 and 98.
S]eeve 94 consiste of a lower segment 94a oE outside dia~
meter slightly less than the diarneter oE the hole which is to be drilled and an upper segrnent 9~b of greater diameter.
The other two sleeves 96, 98 have uniEorm cross-sections z9~33 thLo~3~lolt t;l~?ir l~ni3t~ls.
~ n expandible ari~ lO0 extends between sleeves 94 and 96 and a like arm 102 extends between sleeves 94 and 98. As illustrated the loncJituclinal axes oE both ar~s are oriented at right angles to ti7e Longit~(lina~ axes 0~ the sleeves and the angle between the axes oE the arms is approxi~ncltely 60 de~rees.
A s~ud 10~ extends inward Ero(n each .qleeve. The length oE tile stud determines the distance f)f the hole ~rom the pole in tne manner desc~ihecl below.
Arm 100 consists of a hollow rectangular first sectioll lOOa which is attached to sleeve 94. ~ second rectangular section lOOb is connected to sleeve 96 and is slidingly received in the hollow interior of section lOOa.
sy .neans of set screw 106 the two sections can be locked together in any desired position~ The position of sleeve 94 relative to sleeve 96 can accordingly be increased or decreased~
The construction of arm 102 is the same and its length can likewise be a-]justed by ineans of set screw 108.
Figures 11 and 12 illustrate the manner in which the template can be used to locate the position of the holes which In~st be drilled in the ground. First a hole is drilled beside the place where the pole is to stand. Sec-.Z~ 33 ondly while the pole is resting horizontally on the ground the template is placed beside the lower end of the pole such that the pole is between its arms as illustrated in those Fic;ures. Thirdly the two set screws are loosened to allow t'ne length of the arms to be adjusted until the studs lO~band lO~ccontact the outside wall of thepoleportion.
~he template is then separated from the pole by moving it to the end of the pole.
The lower segment of sleeve 94 is then insertecl into the hole that was drillecl in the ground. ~'he upper secJment which has an outside diameter greater than the cross-section of the hole will remain on top of the hole.
Two more holes are then drilled uSincJ the other two sleeves as guides. The three holes will be correctly located ac-cording to the size of the pole.
In Figure 12 the pole has a smaller outside dia-meter than the pole illustrated in Figure 11 and the length of arms lO0 and 102 are correspondingly shorter to reflect the smaller diameter.
The holes which are drilled must have a cross-sectional area slightly greater than that of the outside wall of the sleeves so that the sleeves can be easily inserted into the holes~ After the holes have been drilled and before the pole is moved into position Eor anchoring, ~?J~Z~33 one sleeve is attached to a pole-mount by inserting its plate 62 into slots 58 so that the sleeve and mount are connected as illustrated in Figure 5.
~ olt 56 is then inserted downwardly through the aperture 74 of the pole-mount and through the central bore of the sleeve and while the sleeve and the mount are out-slde the hole the plug is turned onto the lower encl of the bolt anc] the bo]t is rotated until the upper ends o~ its ribs are just ~,~ithin slots 6~ of the sleeve. The assembly is then inserted into the hole.
The pole is then raised by some suitable means such as hy a mobile crane and is positioned upright beside the pole-mount. The other two pole-mounts are then con-nected to the legs in the manner described above and are placed in position adjacent to the other two holes. The three mounts must be at the same level and shims may be used foc this purpose. The three pole-mounts are then interconnected by means of clamp 26.
