PROVISIONAL SPECIFICATION.
Improved Double-sealed Water Trap.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Robert Baker, of Hamilton, Canada Inventor)
to be as follows: :—
This invention relates to an improved double-sealed water trap, and the invention
has for its object to provide a trap which will more effectually prevent the return
of odours than those at present made and sold.
The construction of my improved trap consists of an open shell or cylinder of
convenient length, and which is contracted at the lower end to the size of an
ordinary pipe to which it is attached. An integral internally projecting flange is
situated about midway the length of the cylinder, and is provided with a central
aperture. A second cylinder of convenient depth, and closed at its lower end with
the exception of central aperture rests upou the internal flange of the firstnamed
cylinder, in which it fits closely.
A piece of metal tube is securely fitted midway its length in the circular
aperture in the bottom of the second-named cylinder, and projects through the
aperture in the flange of the outer cylinder, and into a cup which is supported by
stays, just above the outlet of the outer cylinder firstnamed. The second-named
cylinder has an annular internal flange projecting inwardly, which is adapted to
come into contact with suitable lugs arranged around the outer surface of an
inverted cup or seal having apertures in its sides, and resting upon the bottom of
the secondnamed cylinder, and over the mouth of the tube aforesaid. A stem
projects upwardly from the top of the inverted cup or seal, by means of which the
scal and the secondnamed cylinder is raised when it is desired to pass substances
through the trap.

COMPLETE SPECIFICATION.
Improved Double-sealed Water Trap.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Robert Baker, of the City of Hamilton, in
the County of Wentworth, in the Province Ontario, Canada, Engineer) 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 improvements in double-sealed closet and sink-traps, in
which an outer shell or cylinder having an integral flange for the purpose of
supporting an internal cylinder and a central vertical tube, the upper end of the
tube being sealed by an adjustable metallic seal in conjunction with water; and the
objects of my improvements are, first, to provide a soil and water-trap for closet
purposes and to effectually seal the same; second, to afford facilities for the proper
adjustment of the upper seal and internal cylinder and thorough discharge of the
soil; and third, to provide a sink-trap that will effectually admit, discharge, and
substantially seal the same. I attain these objects by the mechanism illustrated in
the accompanying drawing, in which:
Figure 1 is a vertical section of a machine embodying my invention; Figure 2,

page_text: an elevation of the upper adjustable metallic seal, having a series of openings;
and Figure 3 is a plan of the section of the machine through the broken line, a, a.
Similar letters refer to similar parts throughout the several views.
In the drawings, A is the outer shell or cylinder, its flange, B, denoting its
upper surface when attached to closets or sinks for the admission of water, soil, &c.
The cylinder has an integral flange, C, and secured thereto, water-tight, is its
central tube, D. The internal cylinder, E, fits snugly to the interior of cylinder, A,
and rests upon the flange, C, and the upper seal, F, having a series of openings, H,
is supported by the internal cylinder, E.
I is the lower metal cup-shaped seal, and is held in its rigid position by means of
a series of braces, J.
In operating the trap, the water and soil enter at the upper end of the
cylinder, A, the passage being denoted by arrows, and pass down between the
cylinder, E, and the convex side of seal, F, and through the openings, H, of said
seal, and then upward and down through the centre tube, D, into the concave of
seal, 1, until this seal overflows. Then it passes downward into the lower part of
cylinder, A, and through its outlet, A', to which a length of soil-pipe may be
attached. This pipe attached to the outlet, A.', creates the vacuum in the interior
of the trap, as before mentioned. When flushing the trap for heavy soil purposes,
the upper seal, F, is lifted by means of its attached rod, G. The two or more
lugs, n, on said seal come in contact with the integral rim, o, of cylinder, E, thus
raising the latter until its lower end is brought into close proximity or level to the
upper end of the central tube, D. At this point all the refuse that could not
possibly penetrate through the openings of the seal, is flushed or washed away
down through the tube, B.
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:
In a double-scaled trap, an open shell or cylinder, A, having an internal integral
flange, C, and internal cylinder, E, supported thereon, and a central vertical tube
held therein, said cylinder, E, being open at the top and fitting the tube, D, at the
bottom, said cylinder, E, having an internal rim, O, in combination with the
seal, F, having a series of openings, H, and lugs, n, adapted to engage the rim, o,
the rod, G, attached to the seal, F, and the cup-shaped lower seal, I, held in place
in cylinder, A, substantially as described.
