PROVISIONAL SPECIFICATION.
Improvements in Means or 'Apparatus for Securing Lawn Tennis
Posts and the like in Position.
'I 'FREDERICK HENRY AYRES of 111 Aldersgate Street in the City of
London, Manufacturer and HARRY PITTS of 31 Wycombe Road, Coleraine
Park, Tottenham in the County of Middlesex, Engineer do hereby declare the
nature of this invention to be as follows:-
This invention relates to improved means or apparatus for securing lawn tennis
posts and the like in position in the ground.
'The object of the invention is to enable the screw pins or spiral anchor pieces
such as are used with the well known "Ayres's championship lawn tennis
poles "to be left fixed in the ground during such operations as mowing, rolling
the ground and the like, avoiding the inconveniences attending their removal
and replacement and ensuring replacement of the posts in their exact original
position.
For this purpose the nut head and neck of the top bolt or part of the spiral pin
is connected removably to the spiral stem which is buried in the ground by the
engagement of an enlargement on the neck of the top bolt in an enlarged recess in
the head of the spiral stem. The enlargement of the bolt is dropped into the
recess in the spiral (which like the enlargement is elongated) and then by a
turning movement the two are locked together.
The opening in the head of the spiral is capable when out of use of being closed
against water or other matters by means of stopper, lid or cover piece fitted to the
same provided for the purpose.
The spiral pins can be inserted by means of the usual spanner bar and the
recessed beel of the tennis post socket engaged with the top bolt in usual
manner.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows the upper part of a screw pin or spiral anchor piece partly in section
with a top bolt locked therein.
Fig. 2. shows a screw pin by a plan view and
Fig. 3. the same by a sectional plan view taken on the line - Fig. 1.
Fig. 4. shows by side view and
Fig. 5 by underside view a top bolt or part separately.
Figs. 6. and 7 show by plan view and side view respectively a detail to be
d'escribed.
Fig. 8. shows the spiral anchor piece fixed in the ground, with top bolt in place,
and a spanner for turning the screw.
Fig. 9. shows the position of the spiral anchor piece and top bolt when in place.
The nut head a and neck a' of the top bolt or part 2 of the spiral pin is
connected removably to the spiral stem 6 which is buried in the ground by the
engagement of an enlargement as on the neck of the top bolt in an enlarged
recess in the head of the spiral stem b. The enlargement a³ of the bolt is
dropped into the recess in the spiral (which like the enlargement is clongated)
and then by a turning movement the two are locked together as shewn in
Fig. 1.
The opening in the head of the spiral is capable when out of use of being
closed against water or other matters by means of stoppers, lid or cover pieces c
Figs. 6 and 7 fitted to the same provided for the purpose.
The spiral pins can be inserted by means of the usual spanner bar, d and the
recessed heel e of the tennis post socket engaged with the top bolt a³ in usual
manner.
By these means the top bolt or part a² may be detached when required and
the head of the screw left substantially flush with the ground thus ensuring the
posts being put again into the same position as before.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The improved construction and use of screw pins or spiral anchor pieces for
lawn tenuis posts and the like so that the portions thereof actually anchored or
holding in the ground may be detached from the upper portion and readily
reattached substantially as and for the purposes set forth and shewn by the
drawings.
