PROVISIONAL SPECIFICATION left by the said John Eli Manock at the
Office of the Commissioners of Patents on the 14th June 1883.
JOHN ELI MANOCK of Heywood in the County of Lancaster Moulder
IMPROVEMENTS IN STENCH TRAPS."
My Invention relates to certain Improvements in the Construction of Stench
Traps and consists in the casting or forming of the "box" in parts so that the
top or upper portion thereof carrying the "grid" may be separate or apart from
the lower portion carrying the "trap" but so that it may lie steadily and firmly
thereupon when in position, and to that the top or upper portion may be capable
of removal and renewal if injured or broken without disturbing the lower portion
whereby a saving and economy is effected.

ALLAHOCK 111 the Great Seal Fatent Utice on the
JOHN ELI MANOCK of Heywood in the County of Lancaster Moulder
IMPROVEMENTS IN STENCH TRAPS
My Invention relates to certain improvements in the construction of Stench
traps and consists in the Casting or forming of the "box" in parts so that the
top or upper portion thereof carrying the "grid" may be separate or apart from
the lower portion carrying the "trap" but so that it may lie steadily and firmly
thereupon when in position and so that the top or upper portion may be capable
of removal and renewal if injured or broken without disturbing the lower portion
whereby a saving and economy is effected. And in order that my said Invention
may be fully understood I shall now proceed more particularly to describe the
same and for that purpose I shall refer to several figures on the sheet of drawings
hereunto annexed
Fig 1 is a side view of the loose top
Fig 2. is a side view of the same in position
Fig 3 is a top view of the same all full size
In Fig 1 B B is the framework of the loose top and is cast or formed so as to
carry a grid C which lies upon four flanges cast thereupon two of which are shown
at bb and which is also hinged thereto at c so as to be capable of opening and
shutting In Fig II A A is the framework of the lower portion of the box
carrying the trap and is cast or formed in any suitable shape that shown in the
drawing I have found to answer well and is provided with a partial bottom and
also with a partial top in which latter is an aperture upon which fits a lid a¹ and
it is also provided with two partition sides one of which rises from the bottom
and the other drops from the top thereof in the positions shown at a a and so that
they overlap each other and form what is known as a "trap A flange cast on
the bottom of the said framework ensures its steadiness when set in position and
assists in forming a good joint with the top of the drain as shown at D The loose
top B B carrying the grid is shown lying in position upon the upper rim of tho
lower portion AA carrying the trap and is kept steady thereupon by four snugs
formed by continuations of the aforesaid flanges and in a downward direction and
so as to project into A A as shown at b b and so as to prevent it from sliding
laterally thereupon
"
In Fig 3 B B is the framework C. C. is the grid and b b are the flanges
respectively of the aforesaid loose top when lying in position upon A A and as
viewed from above
In applying my improved Stench trap I fix the lower portion A A firmly upon
the brick or other material forming the top of the drain D puddle it well round
and fill in up to its brim I then place the lid a in its position and puddle it also
round I then finally place the loose top thereupon-Should the outlet D become
at any time choked it will be simply necessary to remove the loose top B B and
the lid a¹ to clear a passage and then replace the same or should the grid C. C.
or any part of B B become injured or broken it can be renewed or replaced without
disturbing A A
I may here remark that in Stench traps as hitherto constructed the upper and
lower portions of the box have been cast together so that any injury to one
part frequently required the removal and renewal of the whole and they were
inconvenient to keep in order Now by my present Invention I avoid this

page_text: trouble and expense and also provide a more convenient arrangement for the
working thereof
Having thus described the naturo and objects of my said Invention together
with the manner in which the saine is to be or may be performed or carried into
practical effect I wish it to be distinctly understood that I claim as secured to me
under the above in part recited Letters Patent
1. The casting or forming of the "box" in parts so that the top or uppor
portion carrying the "grid" may be separate from the lower portion carrying
the "trap
"
2. The general arrangement of parts or any mere modification or imitation of the
above mentioned arrangement of parts when used substantially in the same
manner and for the same purposes as herein before described set forth and
illustrated In witness whereof I the said John Eli Manock have hereunto set
my hand and seal this thirteenth day of December. in the year of our Lord one
thousand eight hundred and eighty three
