PROVISIONAL SPECIFICATION.
Improvements in Combined Posts and Connections for Carrying and
Guiding Signal Wires and for similar Purposes.
I, JOHN AUDLEY FREDERICK ASPINALL, of florwich, in the County of Lancaster,
Engineer, do hereby declare the nature of the said invention, to be as follows :—
For carrying and guiding signal wires, posts of wood have hitherto been generally
used driven or secured into the ground, and the brackets which hold the pulleys for
guiding and carrying the wires have been attached to the wood posts by wood-
screws.
These wood posts soon rot and require frequent renewal, and the brackets are not
so readily secured to them as by my invention, which consists in forming the post
of wrought iron. or steel or other suitable metal, of a cross, T, channel, angle, or
other desired section, the cross section by preference. These metal posts are made
pointed, and in some cases with a screw thread, and can be driven or screwed readily
and firmly into the ground or they may be formed in some cases to be readily
attached to stone, wood or other supports.
Brackets are formed of a shape suited to the cross section of the post, and these
brackets are arranged to pass and slide upon the post, and are then secured thereto
by a bolt or otherwise, or as preferred, by the joint pin, which connects the pulley
frame or carrier to the bracket, upon the post, this joint pin passing through a notch
in one edge of the metal post.
Any desired number of brackets of any suitable form may be readily attached to
the same metal post.
Dated this Twelfth day of March 1889.
COMPLETE SPECIFICATION.
Improvements in Combined Posts and Connections for Carrying and
Guiding Signal Wires and for similar Purposes.
I, JOHN AUDLEY FREDERICK ASPINALL, of Horwich, in the County of Lancaster,
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 :-
For carrying and guiding signal wires, posts of wood have hitherto been generally
used, driven or secured into the ground, and the brackets which hold the pulleys
for guiding and carrying the wires have been attached to the wood posts by wood-
screws.
These wood posts soon rot and require frequent renewal, and the brackets are not
so readily secured to them as by my invention, which consists in forming the post
of wrought iron or steel or other suitable metal, of a cross, T, channel, angle, or
other desired section, the cross section by preference. These metal posts are made
pointed and in some cases witth a screw thread, and can be driven or screwed readily
and firmly into the ground, or they may be formed in some cases to be readily
attached to stone, wood or other supports.
Brackets are formed of a shape suited to the cross section of the post, and these
brackets are arranged to pass and slide upon the post, and are then secured thereto
by a bolt or otherwise, or as preferred by the joint pin, which connects the pulley
frame or carrier to the bracket, upon the post, this joint pin passing through a notch
in one edge of the metal post.

page_text: Any desired number of brackets of any suitable form may be readily attached to
the same metal post.
Fig. 1 is an elevation of a post of metal of cross form in cross section, the bracket
of one pulley being shown in section.
Fig. 2 is another elevation of the same post and pulley brackets as that shown
in fig. 1, but in a plane at a right angle to the plane in which fig. I is drawn.
Fig. 3 is a plan view of the post, one bracket being shown in section.
Figs. 4, 5 and 6 are views corresponding respectively to figs. 1, 2 and 3 of a
metal post formed of a T cross section, but in these views no parts are shown in
section.
a, is the metal post, pointed at a¹, to drive into the ground.
The brackets b, are of cast metal, and of such form as to suit the cross section of
the post a, which is employed, and they can be slied upon the post to the position
required and then secured upon it by the pin b, which forms the joint or fulcrum
pin of the motal holder c, that carries the hearings c', upon which the pulley c³,
rotates.
It will be seen that these joint pins 61, pass through a notch in the age of the
web of the post a, as shown.
These notches may be filed or cut out by a punch or other means, or the posts
may be formed with notches in the edges of their webs at suitable intervals so that
the brackets may be readily applied or removed.
The posts a, may be made of malleable or cast metal and of any desired cross
section, the brackets 6, being adapted to such section.
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. The combination of metal posts (a) with metal brackets (6) carrying holders
of pulleys for guiding signal wires substantially as herein before described and illustrated
by the drawings.
2. The combination of metal posts (a) with metal brackets (b) and the attach-
ment of the two together, by the joint pin (') substantially as herein before described
and illustrated by the drawings.
Dated this Twenty-ninth day of November 1889.
