COMPLETE SPECIFICATION.
Improvements in Metal Posts or Supports for Electric Wires or
Cables, also applicable for other purposes.
I, OSCAR ANDRÉ, residing at Neuilly-sur-Seine, in the Republic of France, 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 has for its object a post or support for electric wires or cables of
all kinds; this post is also applicable to other purposes such as lighting and
signalling.
My invention is illustrated by the annexed drawing in which-
Figure 1 shows the complete post arranged to receive telegraphic wires.
Figures 2 to 8 are detail views on a larger scale.
Figures 2 and 3 are respectively an elevation and a plan of a hoop and wooden
supporting frame.
Figures 4 and 5 are respectively an elevation and a plan of a hoop and corrugated
sheet iron supporting frame.
Figure 6 is an elevation showing a method of scarfing the angle irons³
Figure 7 is a section on the line X X in Figure 6.
Figure 8 is a plan of a hoop and cross form support.
In these figures-
A and A' are the angle irons forming the corners of the posts.
a a projection. a¹ a cavity in the post.
B are tightening hoops.
wooden supporting frames.
D are corrugated sheet iron supporting frames.
F is a hoop for scarfing two ends of angle iron.
G are insulators for telegraphic wires.
As is seen in these figures the post is made up of four uprights of angle iron of
any suitable section arranged pyramidically. These angle irons are supported at
distances apart by supporting frames of wood, corrugated sheet iron or any other
material and metal hoops which I put on either hot or cold.
This arrangement gives very great rigidity to the structure. Very thin sheet
iron may be used for the supporting frames, the corrugations giving them con-
siderable transverse rigidity. Of course the thickness of the sheet iron of the
supporting frames as that of the irons for the corner uprights depends
height of the post and the load it is intended to carry. So also in respect to
the hoops which may be more or less numerous.
I
may
on the
also if need be increase or diminish the number of the uprights of the post
and consequently modify the shape of the hoops and supporting frames. I fix the
posts in the ground in any suitable manner, especially by extending the corners, or
by joining the opposite corners two by two by means of a piece twice bent scarfed
to the corners in any suitable manner. These posts are portable for they can be
aken to pieces with great facility. In addition they lend themselves easily to
decoration of which Figure 1 gives an idea.
I may also in certain cases employ supporting frames in the shape of a cross.
For certain kinds of transport it may be useful to have the angle irons in pieces
of a certain length 3, 4 or 5 metres for example which are then scarfed to form the
prights. This joint of the angle irons does not reduce in any way the strength of
be construction by reason of the method of scarfing shown in Figures 6 and 7 of
he annexed drawing being resorted to.

F is a hoop for scarfing two ends of angle iron.
G are insulators for telegraphic wires.

page_text: The end A¹ has a projection a which fits into a cavity a¹ in the end A. A ring
or hoop F presses upon the whole and the join is perfect.
It may be remarked that the projection is arranged in such a manner that the
lower end inside portion of the angle iron A' presents an oblique sliding surface to
give draught to the hoop.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A metal post or support the corner uprights of which are pyramidically
arranged and held together by means of hoops tightened on wooden supporting
frames as above described and shewn in Figures 2 and 3.
2. A metal post or support the corner uprights of which are pyramidically
arranged and held together by means of hoops tightened on thin corrugated sheet
iron supporting frames as described and shewn in Figures 4 and 5.
3. A metal post or support the corner uprights of which are pyramidically
arranged and held together by means of hoops tightened on a cross frame as shewn
in Figure 8.
4. The method of scarfing the irons forming the corner uprights such as described
and shown in Figures 6 and 7 of the annexed drawings.
5. The combination with the corner uprights of a post, of a twice bent iron
connecting together two by two the corner uprights at their base.
