COMPLETE SPECIFICATION.
Improvements in Metal Bases for Telegraph and other Poles.
I, GEORGE WILLIAM GLAZIER, of Salem, Essex County, State of Massachusetts,
United States of America, Mechanical Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained, in and by the following statement:-
This invention relates to improvements in Metal Bases for Telegraph and other
Poles, and it has for its object to make a firm, strong, durable foundation for the
lower end of such poles, so as to secure it rigidly to the ground.
This device is equally useful for application to old poles, the ground ends of
which may be decayed, as well as for new poles as will hereinafter be more fully
shown and described, reference being had to the accompanying drawings, where
Fig. 1 represents a top plan view of a pole provided with my improved metal
base.
Fig 2 represents a side elevation of the same.
Fig. 3 represents an enlarged cross-section on the line 3-3 shown in Fig. 2.
Fig. 4 represents a longitudinal section on the line 4-4shown in Fig. 2, and
Fig. 5 represents an edge view of one of the sections of the metal base.
Similar letters refer to similar parts wherever they occur on the different parts
of the drawings.
In the drawings A represents a telegraph trolley or similar pole which may be
square, polygonal or circular in section, as may be desired without departing from
the essence of my invention.
To that end of said pole which is above the ground surface B aro secured the
segmental metal base portions C, C, C, C, which are secured to the lower end of
the pole A by means of bolts D, D, going through perforations in the pole and
metal base sections as shown.
D', D, are fastening nuts screwed on the ends of the said bolts as shown.
The lower ends of the base sections C, are made outwardly flaring as shown
at C, C', in the drawings, and are provided with a series of perforations C", C",
which I term the ramming holes through which the earth is rammed by a suit-
able ramming tool into the space between the outwardly flaring base
sections C, C, after the said sections have been placed in a cavity in the ground
as shown.
In practice I make integral with the outside of the said base sections
strengthening ribs C), C, which besides serving as means to increase the strength
and resistance of said sections against a lateral strain caused by wind pressure or
tension of telegraph, telephone, or trolley wires, also serve in a measure to conceal
and protect the heads and nuts of the fastening bolts D, D.
For square poles I prefer to use four angular metal base sections as shewn, but for
polygonal or cylindrical poles more or less such base sections may be used without
departing from. the spirit of my invention.
Telegraph, Telephone and similar electric wire supporting poles are very liable
to become decayed and rotten where they are imbedded in the ground and are
then usually discarded and replaced by new ones, which entails a great loss and

page_text: necessary expense in providing new poles. By my invention the old poles may
be saved simply by sawing off the decayed lower end and attaching to that portion
of the pole above the ground my improved sections which are afterwards inserted
in a suitable post hole in the ground, and firmly rammed in position.
My invention is also applicable as a metal base for new poles of any suitable
form or shape as hereinabove described.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In combination with an electric wire supporting or other pole, a metal base
composed of sections adapted to be secured to the pole and having outwardly
flaring ground portions and ramming perforations in the latter substantially as
and for the purpose set forth.
2. In combination with an electric wire supporting or other pole, a metal base
composed of sections secured to the pole, said sections having outwardly flaring
ground portions, ramming perforations in the latter, and vertical re-enforcing
ribs on the outside of said sections substantially as and for the purpose set forth.
Dated this 31st day of August 1897.
