Ventilation So and Was pipess for purpose
Year: 1885

page_text: I, JOHN DAVIDSON of Knowsley Bank, Church Street Egremont Cheshire,
Bachelor of Medicine and Master in Surgery do hereby declare the nature of this
invention to be as follows:-
My Invention relates to the improvements in the Ventilation of Soil and Waste
pipes, or pipes used for similar purposes. In order that my description, and
specification may be clearly understood, I shall refer to the annexed sheet of
drawings, in which the letters used will indicate the several parts. The scale of
drawings is 1 inches to 1 foot. My Invention consists of a pipe with three arms,
each arm is of the same section as the Soil and Waste pipes. The Lateral Arm A,
one end of which receives the Soil or Waste pipe from the Watercloset basin, while
the other end joins the body of the Ventilator, which is continuous with the Soil
pipe in a tangential manner, and thus avoids any lateral encroachment of the area
of the continued Soil pipe The Second or Lower Arm B, the end of which is
received into the upper end of the Soil pipe. The Third or Upper Arm C, the end
of which receives the lower end of Ventilating pipe, or shaft.
The Structure of my "Improved Soil and Waste pipe Ventilator”.
It may be Single or Multiple,
Section may be round or polygonal.
J
Material employed, may be Iron, Lead, Copper, Zinc, Tin, Terra Cotta,
Earthenware, or any other suitable material.
The following improvements in the Ventilation of .Soil and Waste pipes, I claim
for my "Improved Soil and Waste pipe Ventilator."
1. The thorough Utilization of the upward current of air in Ventilation of Soil
and Waste pipes.
2. The complete exhaustion of foul air of Soil or Waste pipe in connection with
water closet basin.
3. The prevention of sewer gas entering room.containing water closet.
4. The preservation of the vertical continuity of Soil pipe with Ventilating pipe,
or shaft.
r
5. The prevention of any lateral encroachment of area of Soil pipe at the place,
where continuation of Soil or Waste pipe from water closet basin joins it."
6. It secures the proper size of the Ventilating pipe or shaft.
7. The facility with which the "Improved Ventilator" can be attached to the
Soil, Waste, and Ventilating pipes.

Bachelor of Medicine and Master in Surgery do hereby declare the nature of my
invention for IMPROVEMENTS IN THE VENTILATION OF SOIL AND WASTE PIPES OR
PIPES USED FOR SIMILAR PURPOSES 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 the improvements in the Ventilation of Soil and Waste
pipes, or pipes used for similar purposes. In order that my description and
specification may be clearly understood I shall refer to the drawings filed with my
provisional specification in which the letters used will indicate the several parts. I
The scale of drawings is 14 inches to 1 foot. My Invention consists of a pipe with
'three arms, each arm is of the same section as the Soil and Waste pipes. The
Lateral Arm A, one end of which receives the Soil or Waste pipe from the water
closet basin, while the other end joins the body of the Ventilator, which is continuous
with the Soil pipe, in a tangential manner, and thus avoids any lateral encroachment
of the area of the continued Soil pipe. The Second or Lower Arm B, the end of
which is received into the upper end of the Soil pipe. The Third, or Upper Arm C,
the end of which receives the lower end of Ventilating pipe, or shaft.
Section may be round or polygonal.
Material employed, may be Iron, Lead, Copper, Zine, Tin, Terra Cotta, 2
Earthenware, or any other suitable material. .
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
1 claim to be novel is
1. The thorough Utilization of the upward current of air in Ventilation of Soil 2
and Waste pipes.
2. The complete exhaustion of foul air of Soil or Waste pipe in connection with
water closet basin.
3. The prevention of sewer gas entering room containing water closet.
4. The preservation of the vertical continuity of Soil pipe with Ventilating pipe, 3
or shaft.
.
5. The prevention of any lateral encroachment of area of Soil pipe at the place,
where continuation of Soil or Waste pipe from water closet basin joins it.
I
6. It secures the proper size of Ventilating pipe, or shaft.
7. The facility with which the "Improved Ventilator" can be attached to the 3
Soil, Waste, and Ventilating Pipes.
8. The "Improved Ventilator" can be used with advantage as a junction pipe in
drains and sewers.
