Improvements in Grates for Covering Street, Yard, and other Gullies,
and the Methods of Securing the same.
RICHARD WALKDEN of 26 Watery Lane Darwen in the County of Lancaster
Colliery Manager and JAMES COCKER of 22 Florance Street Darwen in the
County of Lancaster Moulder of Fireclay Goods do hereby declare the nature of
this invention to be as follows:-
This invention relates to that description of grate, applicable to street, yard, or
other gullies.
In carrying out our invention, we employ corrugated bars, instead of, or, in
preference to, straight ons, preferably placed in such a manner, that the elevated
portion of one bar, will be opposite the depressed portion of another, which forms
a barrier or obstruction to the flow of water, the said obstruction causing the water
to drop through the openings in the grate, & thus prevents its overflow.
The grate is furnished with a pivot on each of two corners at right angles to
one another. On two corners of the seating of the block or gully top at right
angles to one another two round holes are made to receive the pivots of the grate,
at one corner of the block the piece containing the hole to receive one pivot of the
grate is cut out in the form of a dovetail & removed from the gully or gully top.
To secure the grate the pivot on one side of the grate is placed in the hole in the
gully top prepared to receive it the dovetailed piece cut out is then returned to its
original position either with or without cement thus firmly securing the grate to
the gully top.
In the case of round grates, a hole is made just above the seating of the gully
top, into which a small hook is cemented which encircles one point of the
circumference of the grate & so holds it in position. The grate is also furnished
with three small nugs on the inder side which rest on the seating of the block &
so prevents the tilting of the grate.

Improvements in Grates for Covering Street, Yard, and other Gullies,
and the Methods of Securing the same.
We, RICHARD WALKDEN of 26, Watery Lane, Darwen in the County of
Lancaster, Colliery Manager, and JAMES COCKER of 22, Florence Street,
Darwen in the County of Lancaster, Moulder of Fireclay Goods, 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, that is to say
It relates to the class or description of grate which is applicable for use in
connection with street, yard or other gullies and consists of improvements in the

page_text: formation and construction of these grates and parts appertaining thereto whereby
they are made to auswer their purposes more efficiently than they have done
heretofore as is hereinafter explained, and in order that our said invention may be
readily understood we have hereunto appended sheets of drawings illustrative
thereof to which by figures and letters reference is made in the following
description.
Fig. 1 is a vertical section of a slopstone gulley with our improved grate applied
thereto.
Fig. 2 is a plan or view of same as seen from above, but with the grate removed
therefrom.
Fig. 3 is a plan or top view of a grate, (drawn to an enlarged scale) made in
accordance with our invention.
Figs. 4 and 5 are sectional views on lines A-B and C-D respectively of the
grate shewn by Fig. 3.
Fig. 6 is a drawing in detail to a still larger scale illustrative of the pivotal
joint of our improved grate.
Fig. 7 is a vertical section of a street gulley drawn to a smaller scale than
Fig. 1, and shews our improved grate in position.
Fig. 8 is a vertical section of another form of galley in connection with a slopstone
drain, and illustrates another form of our improved grate.
Fig. 9 is a plan or top view of parts shewn by Fig. 8.
Fig. 10 is top view or plan of a circular grate made in accordance with our
invention.
Figs. 11 and 12 are sectional views on lines E-F and G-H respectively, of
Fig. 10.
Fig. 13 is a sectional elevation same scale as Fig. 6 and shews in detail our
improved form of pivotal bearing for circular grates.
Similar letters and figures of reference indicate similar parts throughout the
several views.
In carrying our invention into effect instead of the grate bars a being straight
or extending evenly across or from side to side of the grates 6 or b¹ we make them
of a corrugated, wavy or zig-zag form as shewn by Figs. 4 and 11, while we
further preferably arrange them so that the raised or elevated portion a' in one
bar a is opposite the depressed or sunk portion a² in its neighbouring bars a by
which means sufficient of a barrier or obstruction is put into the path of the water
flowing over these grates as will cause or guide same to descend through the
openings intervening between these bars a thus the liability of said water to
overflow the gulley is greatly diminished. Although we have shewn the bars a
arranged as above described, we are perfectly aware that they may be arranged
differently and yet attain certain of our advantages.
The rectangular grate shewn by Figs. 1 to 7 inclusive, is furnished with pivotal
projections dd on its opposite corners as illustrated by Fig. 3. One of these
projections being arranged to take into an opening of the seating or frame f while
the other takes into a holding piece g which is made somewhat of a dovetail or
tapering form (see Fig. 1) so that when inserted laterally into a corresponding
opening in the frame f it secures the grate in position either detachably so or
permanently by being cemented or otherwise secured in its said position.
Respecting circular grates, the pivotal hook or holder is secured in the seating
or frame k by cement or otherwise, while its hooked end is arranged to lay-hold-of
the rim of the grate as shewn by Figs. 10, 12 and 13 so that this said grate b¹
is pivotally mounted as desired.
The circular grate has small projections or supporting pieces m formed on its
under surface, to rest upon the seating of the frame or block k by which means
forces acting vertically upon said grate are met by a resistance more evenly
distributed over its whole surface than would be the case provided said grates
had to rest on uneven seatings. It will be readily understood that similar supporting
pieces may also be formed on the rectangular grates.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is ;-
1. A grate for street or like gullies with cross bars formed as described
substantially as and for the purposes specified.
2. A grate for street or like gullies with cross bars formed as described the same
being arranged relatively with each other substantially as specified.
3. The combination with a rectangular grate for street or like gullies of means
for pivotally mounting same substantially as herein set forth.
4. The combination with a circular grate for street or like gullies of means for
pivotally securing same substantially as herein set forth.
5. Grates for street or like gullies formed and constructed substantially as
herein specified.
