A NEW OR IMPROVED STENCH TRAP
Year: 1877

page_text: LETTERS PATENT to Richard Ewart, Contractor, of Ravensthorpe, in the County
of York, for the Invention of "A NEW OR IMPROVED STENCH TRAP."
PROVISIONAL SPECIFICATION left by the said Richard Ewart at the Office
of the Commissioners of Patents on the 3rd February 1877.
RICHARD EWART, Contractor, of Ravensthorpe, in the County of York. "A NEW
OR IMPROVED STENCH TRAP."
This Invention has more especial reference to those kinds of stench traps which
are employed in conjunction with the drains of houses, but it is also applicable to
drains generally where "trapping" is required; and it consists of a funnel or drum
which is encased within an outer covering. In this funnel or drum I arrange &
series of grates from two or more, and I have the finest of these grates at the
bottom, so as to catch any dirt or bits that may get through the top or preceding
ones.
The grates fit loosely in the funnel or drum, and can be removed, so that the trap
can be cleaned out at any time.
The advantage of having more than one grate will be obvious, as the trap will not
require cleaning out near so often, and anything is thereby prevented from getting
to the bottom of the trap, and thus choking it up.
The bottom of the funnel or drum rests sufficiently deep in the water at the
bottom of the trap to prevent any noxious gas arising from the drains or sewers
penetrating into the atmosphere or houses.
The inlet and outlet branch pipes of the traps can be arranged to suit the con-
venience of the place or position where they are fixed.
The "traps" and grates may be made of earthenware, iron, or other suitable
material.

DESCRIPTION OF DRAWINGS.
In order that my Invention may be more clearly understood I have hereunto
annexed one Sheet of Drawings illustrative of the same, and have marked it with
figures and letters of reference, the same letter referring to the same part in the
various views or Figures.
"
Figure 1 is a vertical section of one of my improved stench traps constructed with
a dividing rib or partition, shewn in dotted line, the use and employment of which
is hereafter described.
Figure 2 is a plan view of Figure 1.
Figure 3 is also a vertical section of one of my improved stench traps constructed
without the middle dividing rib or partition.
Figure 4 is a plan view of same.
And Figures 5 and 6 are views of the grates which fit in the funnel of the "trap."
A is the funnel or drum which I employ, which is encased within an outer
covering, case, or box B, and which may be either combined with the same or made
loose thereto. It is within the funnel or drum that I place two or more grates of
different degrees of fineness, always arranging the finest at the bottom, so that any
dirt or bits which may get through the top or coarser ones will be caught at the
bottom by the finer one, and so not stem up the trap at its bottom end and at the
outlet.
I may employ a series of these grates, but I have shewn only two, C and D, on
the Drawing, the same being sufficient to illustrate my purpose.
E are the ledges or projections upon which the grates rest. I make the grates to
fit loosely thereon, so that the trap can be cleaned out when necessary, which will
not be so often, inasmuch as that by the use of the grates, as before described, the
accumulation of dirt and other clogging matters is reduced to a minimum.
It will be observed that the trap is so constructed that the funnel rests sufficiently
deep in the water contained in the bottom of the trap to prevent any noxious gas
arising from the drains or sewers penetrating into the atmosphere or houses; and as

page_text: a further auxilliary to the water I may employ conducting pipes or ventilators, as
shewn on the Drawings, and marked with the letter F, which pipes or ventilators
may communicate with the fall pipes of a building or other convenient sources of
conveyance, whereby any possible arising of stench or gases may be conveyed right
away.
In the caso of the employment of a dividing rib or partition G, as shewn by
dotted line in Figure 1, I arrange the ventilator pipe to come at the side, whereby
the gasos can be more effectually carried away, inasmuch as that (as it will be
observed) the dividing. partition or rib G prevents them circulating all round the
funnel A and casing B, and prevents them getting near the inlet orifice H, which
inlet orifice I arrange somewhat different when I dispense with the dividing par-
tition or rib G, as will be seen on reference to Figure 3, where I make the inlet
extend to the inside of the funnel or druin A, and in which case I arrange the ven-
tilator pipe also different, conticcting same with the top of the trap, as shewn, but
if desirable it can be connected at the side, as in the other case; the positions how-
ever of both the inlet orifices Hand the outlet orifices J, as also the ventilator shafts
or pipes F, may be varied in many ways to suit the convenience of the situation
where the traps may be fixed.
It will be seen that the trap may be employed within or without the house or
building, in fact it may be used as a wash stand if desirable, but it is especially
applicable for the back yards of dwelling houses. They may be made of metal, fire-
clay, or other suitablo substances.
Having thus described the nature of my said Invention, and shewn how the samo
may be employed and put into practice, I would have it understood that I do not
confine myself to the precise details as herein shewn and described, for, as stated,
modification of arrangement in some of the parts may be made; but what I claim
as my Invention and believe to be new is, the construction of "stench traps" in
manner and form substantially as heroin described and illustrated by the accom-
panying Drawings.

thousand eight hundred and seventy-seven.
