COMPLETE SPECIFICATION.
Improvements in the Construction of Traps for Baths, Lavatories,
and other purposes.
I, ISAAC BARNSLEY of Charles Street, in the City of Sheffield, Manufacturer,
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 has for its object to improve the construction of traps of baths,
lavatories and similar purposes and to enable such traps to be readily cleaned out,
and to be of compact form.
I have illustrated the invention in the annexed sheet of drawings, in which
similar letters of reference indicate similar parts in any of the figures.
Fig. 1, a vertical section of a trap for a bath made according to my invention.
Fig. 2, cross section through the body of part C.
Fig. 3, elevation and plan of part D.
In constructing a trap for a bath, such as shown in the drawings, I make the
body of the trap A, with an escape B, of any suitable construction but so as to
leave a weil W, to hold a seal of water.
The upper part is provided with a flange A', and it is screw-threaded internally
at A³, into which the corresponding screw threads of a tubular cap C, engage.
The cap C, has an outer flange C¹, between which and the flange A', the body
of the bath F, is gripped.
The upper part is coned to receive the plug E, but for other purposes, the plug
may be omitted if desired, and in the lower part an internal flange C', is formed
with two gaps C³, by means of which the cap may be readily screwed into
position or removed.
The portion D, which forms the actual trap is removable, it is shown detached
in Fig. 3, it consists of a short tube with a flange D', having preferably a grating Dª,
across the opening to prevent the passage of pieces of soap and the like into the
well W.
It is screwthreaded under the flange and an annular collar D', is screwed upon
it, to hold and compress an elastic ring D³. The annular collar D³, may have a
lug or lugs on its underside to drop into the gaps C³, of the part C, but this is not
material.
The tubular part D, is passed into the part C, and pressed down until the annular
collar D', rests upon the flange C¹, the projecting elastic ring makes a joint against
the sides of C, and prevents the passage of sewer gas or other effluvia.
It may be readily withdrawn by inserting a hooked implement through the
grate D, or when a grate is not used, under the bottom edge D.
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 trap for baths, lavatories, and other purposes, constructed, arranged and
operating, substantially as herein before described, with reference to the annexed
deswing

page_text: 2. In a trap for baths, lavatories and the like, a removable tubular piece D,
either with or without the grating D*, as hereinbefore described and shown, for the
purpose specified.
