COMPLETE SPECIFICATION.
Improvements in Accessible Waste Covers for Lavatory Basins,
Baths, and the like.
I, DANIEL MACFIE, of Milton House Works, Abbeyhill, in the City of
Edinburgh, Gas Engineer, 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 :-
This invention is a development of that described in the Specification of Letters
Patent granted to James Milne No. 9141 of 1895, and it has for its object to
provide for ready removal of the shield or cover fitted over the waste pipe and
overflow chambers of lavatory basins, baths, sinks aud the like.
In the accompanying drawings which illustrate the invention Figure 1 is a
vertical section of the waste chamber end of a lavatory basin showing the waste
shield or cover A fitted in place and the overflow and discharge valve B closed,
and Figure 2 is a like view showing the waste shield or cover A raised and the
valve B in the act of being removed to give access to the waste chamber C.
The waste shield A is of the ordinary disc form, but may be of any other shape,
and is provided with the usual lifting knob a and spindle a' which is attached to the
overflow and discharge valve B. Attached to the under side of the shield A are
a number of brackets D each carrying a roller E of rubber or other elastic
material, the rollers being so disposed in a circle or other form as to closely fit to
the contour of the upper end of the waste chamber C. The waste chamber C may
be formed with an inwardly projecting lip e as shown in order to retain the rollers
and prevent displacement of the shield in raising the waste knob a to open the
discharge outlet, but the lip may be dispensed with when the rollers so closely. fit
the mouth of the waste chamber as to ensure sufficient grip thereon. A hand
grip a is fitted or formed on the shield A for use in the manner represented at
Figure 2 in drawing the shield and valve out of the waste chamber to give access
for cleaning out the latter. The shield is readily replaced in the closed position.
represented at Figure 1 by simply pressing downwards until the rollers pass under
and engage the lip o, no tools being required.
The improved fitting is applicable to a waste chamber composed of a stand pipe
fitted independently of the basin, bath or sink as well as to waste chambers
forming part thereof; and it may be fixed to any kind of slab or ledging with
a part cut out for waste chamber; and the rollers instead of being carried by
brackets may be secured in a tubular extension of the shield adapted to enter the
mouth of the waste chamber.
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:
A removable waste shield, fitted with rubber or other rollers, adapted to engage
with the mouth of the waste chamber or waste pipe or an orifice in the slab or
ledging of a lavatory basin, bath, sink or the like."
