PROVISIONAL SPECIFICATION.
Improvements in Means for Supporting Lawn Tennis Poles, Clothes
Posts, Hammock Posts, and other Posts.
I, WILLIAM HENRY GRAY of 36 George Street Chesterton in the County of
Cambridge, Manufacturer of Games do hereby declare the nature of this invention
to be as follows:-
These improvements are intended to facilitate the secure fixing of poles, posts or
supports for a line, netting or other object stretched between them or between one
of them and a house wall or other fixed object. I provide for each pole an anchor
in the form of a spear, of bayonet rectangular ribbed cruciform or other suitable
section and provided with an eye, hinge part or other means of connection at its
upper end. This spear is driven into the ground outside of the post in a slanting
direction with the point towards the spear at the opposite pole or support, so as to
counteract the strain on the line, netting or other object suspended or stretched
between the two poles or supports. To the eye hinge or other connecting part of
the spear which eye is just above the ground I connect by a joint pin or otherwise
a bedplate with corresponding eyes, eye or hinge lugs, or I provide ball and socket
joint or I form a hooked end or turned up nose on the spear which enters a corre-
sponding hole in the bedplate. The latter is formed with a dovetail chace for a
dovetail lump on the bottom of the pole to enter or vice versa the lump may be on
the bed plate and the chace in the bottom of the pole the sides of the dovetail chace
and lump being slightly taper to give draught and secure fixing. The bottom of
the pole should be of metal or the whole pole may be made of metal such as an
iron tube with the bottom dovetail part cast or fixed in.
The bedplate is continued beyond the pole socket and the end of it may be made
broad or with splay feet to give firm footing even when the ground is somewhat
uneven. By packing or wedging up under this end or by driving down the spear
at the other end the pole may be drawn up straight if required say because of
uneven ground.

Improvements in Means for Supporting Lawn Tennis Poles, Clothes
Posts, Hammook Posts, and other Posts.
I, WILLIAM HENRY GRAY of 36 George Street, Chesterton in the County of
Cambridge, Manufacturer of Games 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 :-
These improvements are intended to facilitate the secure fixing and the easy
detaching of poles, posts or supports for a line, netting, hammock or other object
stretched between them or between one such and a house wall or other fixed
object.
In the accompanying drawings I have illustrated the invention as applied and
applicable to the fixing of lawn tennis poles,
Figure 1 shewing such a pole in side view;
Figure 2 is a detail side view of lower end of pole,
Figure 3 an and view of sama

page_text: Figure 5 an end view of same,
Figure 6 a plan of the bed plate and.
Figure 7 plan of underside of same..
I provide for each pole A an anchor in the form of a spear B of bayonet,
rectangular, ribbed, cruciform or other strong suitable section and provided with an
eye, hinge part B' or other means of connection at its upper end. This spear B is
driven into the ground outside of the post A in a slanting direction with the point
towards the spear at the opposite pole or support as shewn in Figure 1 and also. in
dotted lines in Figure 4, so as to counteract the strain on the netting C or the line,
hammock or other object suspended or stretched between the two poles or supports,
or between one such and a house wall or other fixed object. To the eye, hinge
part B or other connecting part of the spear B I connect by a joint pin or
otherwise a bedplate D with corresponding eyes, eye or hinge lugs or I provide
ball and socket joint, or I form a hooked end or turned up nose on the spear B
which enters a corresponding hole in the bedplate D. The latter is formed with a
dovetail chase D¹ for a dovetail lump A¹ on the bottom of the pole to enter. Or
vice versa the lump may be on the bedplate D and the chase in the bottom of the
pole, the sides of the dovetail chase and lump being slightly taper or converging to
give "draught" and secure fixing. The bottom of the pole should be of metal or
the whole pole may be made of metal such as an iron tube with the bottom dovetail
part cast or fixed in.
The bedplate D is continued-beyond the pole socket and the end of it may be
made broad as shewn at D' or with splay feet to give firm footing even when the
ground is somewhat uneven. By packing or wedging up under this end or by
driving down the spear B at the other end of the bedplate the pole A may be
drawn up straight if required say because of uneven ground.
It will be noted that by this construction no guy ropes are required and that the
poles can easily be erected and as easily disconnected from the bedplate D; or the
latter may be disconnected from the spear B by removing the joint pin at B¹,
the spear B remaining in the ground if desired. The bedplate D if left connected
to the spear is easily turned out of the way as shown in dotted lines in Figure - 1
to make room for the lawn mower, the roller or the marker to pass over the
court.
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 pole fixing appliance consisting of an anchor or spear which is jointed or
connected to a bedplate having a dovetail chase and the pole or pole shoe being
provided with corresponding dovetail lump for the purpose of easily fixing and
detaching the pole substantially as set forth.
2. The construction of appliance for easily fixing and detaching a lawn tennis or
other pole as shewn on the drawing.
