uni'rso stares PATENT GFFEQE RALPH H. MANSON, OF PITTSBURGH, PENNSYLVANIA, ASSIG-NOR TOHUBBARD 8: COM PANY, A CRIP0IPulJlIOl'l OF PENNSYLVANIA POLE BRACKET Application 'filed May 29,
This invention relates to supports and more particularly to an adjustable pole bracket for telephone or telegraph poles or the like, for use in supporting different types of fixtures in position on the pole, for example, as is disclosed in my co-pending application Serial No. 335,199, filed Jan. 26, 1929.
In modern pole line construction the poles themselves are commonly of concrete, metal,
or the like, and of diiierent diameter at differcnt heights. Concrete poles and fabricated steel poles are generally designed on a taper of on -quarter inch per foot from top to bottom. Poles formed of common piping,
such as trolley poles, generally include sev eral sections of different sizes telescopically arranged.
An object of this invention is to provide an adjustable pole bracket for use in securing fittings on poles constructed and arranged to be of use with poles of diflerent diameters, or for use with the varying diameter of tapered poles.
A further object is to provide a flexible pole bracket of the type set forth constructed and arranged so as to be capable of securing various types of fixtures to the pole.
These and other objects which will be apparent to those skilled in this particular art are accomplished by means of the invention illustrated in the accompanying drawing in which Fig. 1 is a plan view of a bracket constructed in accordance with one embodiment of this invention showing the pole to which it is secured in section. Fig. 2 is a similar view of a modified construction and Fig. 3
is a view of the clamping strap and asso ciated clamping member of Fig. 2 in separated relation.
In Fig. 1, the pole 5 is of any commercial type and the particular embodiment of the invention therein illustrated includes a fiX- ture attaching collar 6 having a bolt pocket 7 or the like having an opening 8 formed centrally therein through which the shank of the fixture supporting bolt may extend,-
the head of the bolt lying within the recess formed by the pocket 7, as will be readily understood by those skilled in this particular art. A clamping band 9 is associated with 1929.v Serial No. 366,874.
cludes a fixture supporting strap 13 having j a pocket 14 similar to the pocket '2' above described and provided with perforated clamping ears 15 extending outwardly from each end thereof. A clamping strap 16 is also provided with similarly arranged ears 1?. A reinforcing and clamping member 18 is provided for cooperation with each clamping ear of the two strap members and, as illustrated, the clamping member 18 has reinforcing flanges 19 extending outwardly therefrom and adapted to engage the pole along the inner edges when in position. These flanges cooperate with a short lip 20 to provide a pocket 21 for receiving the associated clamping ears 15, 17. The portion of the clamping member adapted to overlie the associated ear is provided with an oval opening 22 adapted to coincide with the perforation in the associated clamping ear to permit a clamping bolt 23 being positioned so as to extend therethrough as illustrated inFig, 2. By forming the opening 22 as an oval, provision is made for slight variation in the position of the-perforations in the clamping ears 15, such as many occur in commercial production.
It will be apparent that, with the arrangement illustrated in Fig. 1, the clamping strain train resisting flanges 12 will be resisted by the strain resisting flanges g 12 located on each side of the clamping ears 10 and joining the edges of these cars to the adjacent edges of the strap member proper.
It, will also be apparent that the arrangement illustrated in Fig. 2 provides a separable strain resisting member having pole engaging flanges which absorb the clamping strains in such a Way as to prevent distortion of the associated clamping cars, but at the same time permitting the strap members to be clamped to the pole with suflicient grip to support any fixture desired.
WVhat I claim as new and desire to secure by Letters Patent is:
1. A fixture support for poles including a strap member havinga pocket for receiving the head of a fixture supporting bolt and outwardly extending clamping ears on the ends thereof, a clamping band for said strap member having outwardly extending ears on the ends thereof, clamping members overlying said ears and having rein-forcing flanges adapted to seat on said pole and a clamping bolt extending through said members and said ears for securing saidfixture to the pole.
2. A. fixture support for poles including a strap member having a pocket therein for receiving the head of a fixture supporting bolt, perforated ears formed on the ends thereof, an associated clamping member for said strap member having perforated ears formed on the ends thereof, a perforated separable reinforcing member adapted to fit over each of said ears and provided with strain resisting flanges engaging the associated pole anda clamping bolt'extending through said members and said ears for securing said fix ture to the pole.
8. In an adjustable fixture support for poles including a strap member having a pocket therein forming a recess for receiving the head of a fixture supporting'bolt and outwardly extending clamping ears on the ends thereof, a clamping band for said strap member having outwardly extending ears on theends thereof, reinforcing clamping members for said ears having a flat portion, a
downwardly projecting lip on said flat portion and downwardly pro ect1ng strain reslstlng flanges-on the sidesof said flat portionadapted to engage the pole, said lip and said flanges forming a recessfor receiving the clamping ears on said strap members and means extending through aligned openings in said reinforcing members and said ears for securing said-strap members around said pole.
4:. In an adjustable fixture support for poles having-complementary strap members providedwith outwardly extending perforatedclampingearson the ends thereof, a reinforcing clamping member for each of said ears-having a flat portion adapted to overhe said clamping ear, a lip on the edge of poles having complementary strap members provided with outwardly extending perforated clamping ears on the ends thereof, a reinforcing clamping member for each of said ears having a flat portion, an oval opening therein adapted to align with the perforations in said ears, a downwardly projecting lip thereon, downwardly projecting strain resisting flanges on each side thereof adapted to seat against said pole, said lip and said strain resisting flanges forming a recess for receiving said perforated clamping ears, and a clamping bolt extending through said aligned openings in said strain resisting members and said ears for securing said strap members around said pole.
In testimony whereof, I have hereunto subscribed my name this 27th day of May, 1929.
RALPH H. MANSON.
said flat portion and strain resisting flanges on each side of saidflat portion adapted to seaton said pole, and a clamplng bolt extending throughopenings in saidstrain resisting members and said ears. for securing said strap members around said pole.
