PROVISIONAL SPECIFICATION.
Improvements in Earthenware Traps and Gullies, and Blocks for
Covering Traps, Gullies, or Bends, and the Method of Securing
Metal Grates to same.
I, JESSE KIRKMAN of Park Place Chorley in the County of Lancaster Steam
Packing Manufacturer do hereby declare the nature of this invention to be as
follows
This invention relates to that description of traps & gullies used to convey slop
water or rain water to the main sewer and so prevent the ascension of sewer gas up
the slopstone or other pipes.
In my invention I employ a piece or block of earthenware preferably oblong say
for example 18 x 12 x 4 inches more or less as the case requires hollowed
or channelled out and gradually sloping from one end for about nine inches more
or less. At the end of this slope I prepare a seating (with a hole on one side and
a slot on the other side of the seating) to receive a square or oblong metal grate also in
connection with the grate and seating I construct a suitable aperture to communicate
with a trap or gully. The grate is furnished with a pivot on each of two corners at
right angles to one another one of which fits into the said hole near the seating on the
block and the other pivot on the grate is passed along or down a slot to its place on the
other side of the seating the remaining portion of the slot being filled with Portland or
other cement to secure the grate in its position thus allowing the grate to be raised on
one side while the trap or gully is being cleaned. If I use a round grate I attach a
lug or ear to it which is secured in a cavity cut in the block by a pin passing
through a hole in the lug the remaining part of the cavity being filled with cement.
This method of securing a round grate is applicable to a square or an oblong block,
or to a square trap or gully.
Immediately under the grate or aperture I provide a round or square rim of
earthenware and the block may be used either as a covering for a trap or gully or
the block and trap may be made of one piece of earthenware complete.
I may also employ the method of securing an oblong or square metal grate with
pivots as above described either to a square. trap or gully or to a square block of
earthenware.

COMPLETE SPECIFICATION.
Improvements in Earthenware Traps and Gullies, and Blocks for
Covering Traps, Gullies, or Bends, and the Method of Securing
Metal Grates to same.
I, JESSE KIRKMAN, of Park Place, Chorley in the County of Lancaster,
Steam Packing 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 relates to that description of trap and gullies used to convey slop
water or rain water to the main sewer, and so prevent the ascension of sewer gas
up the slopstone or other pipes.

page_text: And in order that this my invention may be the better understood I have
appended the accompanying sheet of drawings in which
Figure 1 represents a sectional elevational view of my improved device; and,.
Figure 2 a plan of same.
Like letters of reference indicate corresponding parts throughout the views.
In accordance with this my invention. I employ a piece or block of earthenware,
porcelain or the like, (preferably oblong) a. Said block may be straight,
channelled, or hollowed out at its sides and end as at ; and, the bottom of
same is formed gradually sloping from its inlet end, to the gulley trap as
shown at c.
At the end of this slope c I provide a seating with a hole on one side and a slot
on the other, the same being preferably higher than the seating,-employed for the
reception of the lugs or pivots e formed on each side of the grate or grid d, one of
which is first put into the hole and the other is then slid into or along the slot up
to the end, when the remaining portion of the slot is filled up with Portland cement
or other suitable material thus allowing the grid d to be raised and lowered when
the gulley or trap is being cleaned.
Immediately underneath the block a I secure a ring of eartheuware to which
is attached a gulley elbow or bend g, which can be either at the end or either of
the sides; or, I may if desired, make the block and trap in one complete piece of
earthenware.
I may in accordance with my invention, by preparing the block for the purpose,
employ a round grate or grid which may be loosely attached to the block by the
usual method.
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 1
claim is :-
First. In earthenware traps and gullies the employment of the block a having
either straight, hollowed or channelled sides and end combined with a sloping
bottom c substantially as herein set forth and shewn in the accompanying sheet of
drawings.
Second. Improvements in earthenware traps and gullies and blocks for covering
traps and gullies or bends and the method of adapting and securing the metal
grids thereto, substantially as herein described and shown in the accompanying
sheet of drawings.
