Complete Specification Left, 17th Nov., 1893-Accepted, 30th Dec., 1893
PROVISIONAL SPECIFICATION.
Improvements in Ground Sockets for Tubular Posts for Telegraphic
and other Purposes.
We, SIEMENS BROS. & Co. LD. and RICHARD VON FISCHER-TREUENFELD,
all of 12 Queen Anne's Gate, Westminster, in the County of London, Electrical
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the ground sockets for receiving and
supporting tubular posts so as to secure greater stability, the means of fixing the
post in the ground socket being by preference similar to that described in the
Specification to May's Patent No. 18718 of 1888 for securing lengths of tube
together.
Fig. 1 of the accompanying drawings is a vertical section of a tubular post
secured in its ground socket constructed according to the present invention and
Fig. 2 shews a modified form thereof.
The ground socket B consists of a tube the lower inside end of which is shaped
conically at C and the upper inside end of which is screwed at D. The post A
which is preferably a tapered wrought iron or steel tube and which may be formed
of one or more lengths joined together, being inserted into the socket B sets firmly
in the conical seating C thereof. The annular space between the two tubes may
then be filled in with concrete, cement or such like material, but at the upper end
of the socket it is preferred to secure the post A in position by a ring R which is
tapered and has an external thread nearly fitting the internal screw thread of the
socket at D. The ring R is split at one side and has notches in its upper edge to
receive a spanner by which it can be screwed in.
Owing to its taper form, as it is screwed into the socket, the ring R is made to
grasp firmly the tube A, and hold it securely in position.
The ground socket is preferably made of cast iron with either a flat base and
flange and ribs as shewn in Fig. 1 or it may have a pointed end so as to be capable
of being driven like a pile by means of a rammer.
In places where poles have to be erected in sandy or very light ground, the base
of the ground socket is preferably supported by a buckled plate P on which it rests.
In order to secure a firmer connection with this buckled plate the latter is provided
with a projecting part S which takes into and nearly fits the lower open end of the
ground socket as shewn in Fig. 1, or the lower end of the ground socket may be
formed as shewn in Fig. 2 with a projecting part S which takes into and nearly fits
an opening in the buckled plate.
Dated this 23rd day of March 1893.

We, SIEMENS BROS. & Co. LD. and RICHARD VON FISCHER-TREUENFELD,
all of 12 Queen Anne's Gate, Westminster, in the County of London, Electrical

same is to be performed to be particularly described and ascertained in and by the
following statement :―
This invention relates to improvements in the ground sockets for receiving and

page_text: supporting tubular posts so as to secure greater stability, the means of fixing the
post in the ground socket being by preference similar to that described in the
Specification to May's Patent No. 18718 of 1888 for securing lengths of tube
together.
Fig. 1 of the drawings accompanying the Provisional Specification is a vertical
section of a tubular post secured in its ground socket constructed according to the
present invention and Fig. 2 shews a modified form thereof.
The ground socket B consists of a tube the lower inside end of which is shaped
conically at C and the upper inside end of which is screwed at D. The post A,
which is preferably a tapered wrought iron or steel tube, and which may be formed
of one or more lengths joined together, being inserted into the socket B sits firmly
in the conical seating C thereof. The annular space between the two tubes may
then be filled in with concrete; cement or such like material, but at the upper end
of the socket it is preferred to secure the post A. in position by a ring R which is
tapered and has an external thread nearly fitting the internal screw thread of the
socket at D. The ring R is split at one side and has notches in its upper edge to
receive a spanner by which it can be screwed in.
.
Owing to its taper form, as it is screwed into the socket, the ring R is made to
grasp firmly the tube A, and hold it securely in position.
The ground socket is preferably made of cast iron with either a flat base and
flange and ribs as shewn in Fig. 1, or it may have a pointed end so as to be capable
of being driven like a pile by means of a rammer.
In places where poles have to be erected in sandy or very light ground, the base
of the ground socket is preferably supported by a buckled plate P on which it rests.
In order to secure a firmer connection with this buckled plate, the latter is provided
with a projecting part S which takes into and nearly fits the lower open end of the
ground socket as shewn in Fig. 1, or the lower end of the ground socket may be
formed as shewn in Fig. 2 with a projecting part S which takes into and nearly fits
an opening in the buckled plate.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A ground socket for receiving and supporting a tubular post for telegraphic and
other purposes, substantially as herein described.
