PROVISIONAL SPECIFICATION.
Improvements in and relating to Plug Sockets of Gratings for
Carrying Off Waste from Sinks, Baths, and the like.
I, SAMUEL GEORGE MASON, of Dale End, Birmingham in the County of
Warwick, Brassfounder, do hereby declare the nature of this invention to be as
follows :-
This invention relates to an improved arrangement whereby the plug sockets of
gratings for carrying away waste water etc. can be easily & effectually cleansed
from any refuse that may become lodged therein, and it consists in forming a
horizontal groove or channel in the interior of the chamber of the socket by
cutting or casting the same therein.
This groove or channel has an upper and lower rim projecting round same, the
upper rim having vertical slots at intervals situated where required. A loose
perforated plate or grating is provided of any suitable shape made with projections
or snugs upon the same which correspond in position with the slots in the upper rim
of the groove or channel into which the plate has to fit.
To fix the loose grating in place in the socket it is merely necessary to pass it
into position, the projections or snugs being received in the slots in the rim of the
groove or channel, the grating can then be locked firmly by turning the same in
the groove by means of a knob or ring for the purpose, the projections or snugs
passing under the rim.
When required to remove the loose grating from the socket by turning the same
the reverse way, the projections or snugs will come opposite the slots in the rim. of
the groove or channel when the grating can be taken out and the bore of the
socket and connections readily cleansed.
For all purposes such as baths, lavatories, sinks, and wherever gratings are used
my improvements will be found of great advantage, by reason of the simplicity of
construction, and the facility by which the loose grating can be removed.

COMPLETE SPECIFICATION
Improvements in and relating to Plug Sockets of Gratings for
Carrying Off Waste from Sinks, Baths, and the like.
I, SAMUEL GEORGE MASON of Dale End Birmingham in the County of
Warwick Brassfounder 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 :-
My invention relates to an improved arrangement whereby plug sockets of
gratings for carrying away waste water etc. can be easily and effectually cleansed
from any refuse that may become lodged therein.
I will proceed to describe my invention with the assistance of the accompanying
drawings in which :
Figure 1. is an elevation of a plug socket.
Figure is a plan of the loose grating in connection therewith.

page_text: Figure III. is a horizontal section through interior of plug socket shewing the
grating in position.
Figure IV. a similar section with grating removed.
Figures V. and VI. are vertical sections.
For my purpose I form a horizontal groove channel or recess at A in the interior
of the chamber of the socket B. by cutting or casting the same therein, this groove
channel or recess has an upper and lower rim or flange the upper one shewn at C
and lower one at C₁ Figs. V. and VI. projecting round the sides, the upper
rim having vertical slots or apertures D at certain intervals and situated where
required. A loose perforated plate or grating E is provided which may be of any
suitable shape and having projections or snugs F. forming ear pieces upon same
which correspond in position with the vertical slots or apertures D. in the upper
rim of the groove or channel in which the loose plate or grating E has to fit.
The action is thus.
In order to fix the loose perforated plate or grating E in place in the plug
socket B. remove the plug or stopper B it is then merely necessary to pass the
grating down into position, the projections or snugs F being received in the vertical
slots or apertures D. in the upper rim C of the groove channel or recess A. the
perforated grating can then be locked firmly by turning the same in the groove or
channel by means of a ring or knob G for the purpose, the projections or snugs F
passing under the rim or flange C and being thus held securely and firmly; the
perforated grating resting upon the lower rim or flange C¹.
When required to remove the grating from the plug socket by turning the same
the reverse way the projections or snugs will come immediately opposite the slots
or apertures in the rim or flange, when the grating can be taken out and the bore
or chamber of the plug socket and connections readily cleansed.
For all purposes such as baths, lavatories, sinks and wherever gratings are used
my improvements will be found of great advantage by reason of the simplicity of
construction and the facility by which the loose grating can be removed.
I do not limit myself to the precise arrangement herein set forth and illustrated
as I may vary the same in any convenient manner without departing from the
principle of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is.
Firstly. In plug sockets the particular formation and arrangement of parts
constituting my invention for the purpose substantially as set forth and described.
Secondly. The particular formation and arrangement (or other similar formation
and arrangement) of the interior of the plug socket for the reception of a loose
perforated plate or grating as set forth described and illustrated.
Thirdly. The adaptation and application of a loose perforated plate or grating
in connection with plug sockets and such like in the manner described and illustrated
or by other similar acting means and for the purpose set forth.
Dated this 30th day of July A.D. 1894.
