Accessible Waste, adapted for Basins, Sinks, Baths, and similar
Appliances.
I, JAMES MILNE, Engineer, Milton House Works, Abbey hill, Edinburgh, do
hereby declare the nature of this invention to be as follows.
-
Improved construction of basins, sinks, baths, and such-like, whereby the waste
cover can be fixed, or removed by the hand, without the application of tools, or
the use of screws, bolts, or other mechanical appliances.
The waste cover remains secure during ordinary use, but by a slight exertion it can
be removed along with the overflow pipe and waste valve, thereby allowing the
waste pipe chamber, and convections thereto to be examined and cleaned throughout
without the assistance of skilled labour
In connection with the filling and emptying of baths, sinks, basins, and similar
appliances the advantages of a standing waste overflow bave been freely admitted,
but this method has been objected to on sanitary grounds owing to the difficulty
of access for cleansing purposes, and the removal of such foreign matter as may
from time to time interfere with the watertightness of the valve. To meet these
objections, while retaining the advantages of the concealed waste, the present
invention has becu designed By this invention the cover which supports the
waste pull is made of a suitable diameter to fit into the entrance of the waste
chamber, which chamber is large enough to admit of easy access by hand for
cleansing purposes. Instead of being fixed by screws, bolts, or other permanent
fixing, requiring the application of tools, and the aid of workmen in removing for
access or in re-fixing, this cover is held in position by n slip fixing, in such a
manner that while it resists the ordinary effoit used in raising the waste pull, it
may be released or refixed by a single movement, and without the application of
tools.
The fixing 18 preferably a ring of rubber, or other suitable material, which may
be either inserted in a groove made in the entrance or lining of waste-chamber, or
in the waste cover itself, the waste cover being held in its place by the friction of
the rubber ring against the surface of the waste-chamber entrance on lining, or
the waste cover as the case may be. Instead of, the ring the fixing may be
alternatively effected by one or more studs, for slip or buy onet fixing, or by one or
more spring catches, or by any other similar suitable means.

KK the rubber ring, which in conjunction with the projection II. H_makes
tight the fitting of the cover.
L the grating communicating between the basin, sink, bath or similar appliance
and the waste-pipe chamber.
In Figure 1 the waste-pipe chamber and stand-pipe are shewn in section, the
valve being closed, and the waste shield being held in position by the
projection HH engaging with the ruble band K K.
Figure 2 also shews the waste-pipe chamber and stand-pipe in section, with the
waste shield still heid in position as in Figure 1, but with the valve E opened for
discharge as in ordinary use, and supported in that position on the shield.
In Figure 3 the waste-pipe chamber and stand-pipe are still shewn in section,
but the waste shield has been disengaged from the projection H H by a slightly
greater effort than that required to open the valve as in Figure 3, and the entire
stand-pipe and waste shield have been bodily withdrawn by hand for cleansing
purposes.

page_text: 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 18:
1. The application to baths, basins, sinks, or similar appliances of a waste-pipe
chamber of sufficient dimensions to admit the band to every part of it, such
chamber directly communicating with the interior of the basin, sink, bath o
similar appliance.
2. The application to the waste-pipe chamber of baths, basins, sinks and similar
appliances of a cover secured by the means above described, so that it will remain
in position during ordinary use, but to permit of cleansing operations can be with-
drawn and replaced without the application either of tools or of skilled or other
labour. All substantially as shewn in the accompanying drawings and set forth in
the foregoing Specification
