PROVISIONAL SPECIFICATION.
Improvements in Cricket Stumps.
We, JOHN BULBECK CORNEY, Merchant, and JOHN FRANCIS, Engineer, both of
70 Little Britain in the City of Londou, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improvements in cricket stumps its objects being to
prevent the cutting up of the ground by the wearing of large holes owing to the
frequent resetting of such stumps, and to enable them to be readily set up or to regain
their position after being struck.
To this end we provide a suitable bed plate having three sockets thereon which is
fixed in the ground by spikes, by screwing, or in any other convenient way. Into
these sockets the wooden stumps are wedged, or are held in a suitable manner.
The stump sockets may be carried by a ball and socket joint or be held upright by
a spring, either of which will allow of the stump after being knocked down being
readily replaced in position. Or the socket may be mounted on a spiral spring, or on
rubber, so that after being struck it will spring back again into place.

COMPLETE SPECIFICATION.
Improvements in Cricket Stumps.
We, JOHN BULBECK CORNEY, Merchant, and JOHN FRANCIS, Engineer, both of
70 Little Britain in the City of London, 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:-
Our invention relates to improvements in cricket stumps the objects being to
prevent the cutting up of the ground by the wearing of large holes owing to the
frequent resetting of such stumps, and to enable them to be readily set up or to
regain their position after being struck.
To this end we provide a suitable bed plate which is secured in the ground by
spikes, by screwing or in any other suitable way, said plate carrying the stumps
which are mounted on ball socket joints attached thereto.
To clearly explain the nature of our invention reference is made to the accompanying
drawing in which :-
Fig. 1 is an elevation of three stumps mounted upon a bed plate in accordance
with our invention.
Fig. 2 is a plan view of the bed plate and the ball members of the sockets.
Fig. 3 is an enlarged view in section of the ball socket joint, part of the bed
plate and stump.
The stumps a are preferably inserted in metal holders or sockets 6 which are
formed with a chamber c in which the ball members d are held. These balls d of
which there are three are secured on the bed plate e which is held in the ground by
spikes f. The balls are held in the socket chamber c by means of the cup shaped
piece g which is screwed to the holder b, said ball bearing against a metal washer i
which is hollowed out slightly to receive it and which bears in turn against a rubber
ring or other compressible washer j.
It will be evident that this joint may be constructed in different ways to that
described, as for instance the ball member might be carried by the stump a and the
socket member by the bed plate e, or the bed plate might be dispensed with and the

page_text: ball socket joint of each stump be attached to a spike, so that each stump would be
separately driven into the ground.
The arrangement described provides a convenient means for mounting stumps
especially for practice purposes when they are frequently knocked down so that the
ground becomes much cut up by the many resettings of same.
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 :-
A cricket stump or stumps pivotally connected to a spike or bed plate by means o
a ball socket joint or the like, substantially as and for the purpose described.
