Improvements in Pathway Curbs and Culvert Covers.
I, GEORGE PETER GROSS, of the Village of Rockaway Beach, in the County of
Queens, State of New York, Plumber and Gas Fitter, do hereby declare the
nature of this invention to be as follows; -
The object of my invention is to provide a covering for the inlet of a sewer or
drain culvert, which, though compact and fully protecting the inlet, will permit
easy access to the sewer and at the same time prevent the filling of the inlet with
sediments, obstructing the passage for water.
The object of my invention is further to provide a covering composed of easily
separable parts, fitted and so combined together that though any of its parts may
be removed without disturbing the others, the covering will be yet compact and
safe at all times.
For these purposes I construct a combined curb piece and culvert cover, composed
of two separate parts, of which the one part consists of a retangular manhole
frame, adapted to be built into the roadway, while the other part consists of a
hollow casting rising above the said frame on the side thereof next the path-
way and constituting a portion of the curb of the latter.
The manhole frame has a continuous vertical rib or flange running round three
of its sides, while on the fourth side, which projects underneath the pathway,, it
has an upward projecting flange which may either be hollow or solid and which
is separate from the flange round the other sides, this being made to stop short of
it a sufficient distance to admit between them the hollow curb piece. This fits
with its inner or back surface against the said inner flange of the
manhole plate, this being consequently formed with the same curved,
polygonal or other configuration as the back face of the curbpiece.
Projecting from this flange are dowels which fit into corresponding holes in the
back face of the curb piece so as to secure the two parts together.
Projecting from the front side of the curb is a horizontal ledge or a bead having
a groove at the same level as an inward projecting ledge formed on the inner side
of the beforementioned flange extending round the three outer sides of the man-
holes frame, and which, together with the ledge or groove on the face of the curb
serve to receive the manhole cover. The edge of the latter next the curb has dowels
projecting from it which fit into holes in the curb, and thus effectually secure the
cover in position.
The outer face of the curb is made either vertical, or inclined outwards or in-
wards, and is formed with slots or as a grating for the escape of water; from the
roadway down the manhole it is also provided with a projecting bead for protecting
its face from the wheels of vehicles. The manhole cover may also be formed with
openings for the escape of water; it is strengthened by suitable ribs on the under-
side.
The top surface of the curb is on a level with and forms part of the pathway
being in some cases provided with a flange extending backward to some extent.

page_text: The ends of the curb piece are adapted to receive the ends of the adjoining stone
or wood curbs and are keyed thereto so as to be securely held in position.
The manhole frame and cover instead of being rectangular may be semicircular,
elliptical or any other configuration suited to the culvert or manhole.

Improvements in Pathway Curbs and Culvert Covers.
I, GEORGE PETER GROSS, of the Village of Rockaway Beach, in the County of
Queens, State of New York, Plumber and Gas Fitter, 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;-.
The object of my invention is to provide a covering for the inlet of a sewer or
drain culvert, which, though compact and fully protecting the inlet, will permit
easy access to the sewer and at the same time prevent the filling of the inlet with
sediments, obstructing the passage for water.
The object of my invention is further to provide a covering composed of easily
separable parts, fitted and so combined together that though any of its parts may
be removed without disturbing the others, the covering will be yet compact and
safe at all times.
..
For these purposes I construct a combined curb piece and culvert cover composed
of two separate parts, of which the one part consists of a retangular manhole
frame, adapted to be built into the roadway, while the other part consists of a
hollow casting rising above the said frame on the side thereof next the path-
way and constituting a portion of the curb of the latter, as I shall describe referring
to the accompanying drawings.
Fig. 1 is a plan of the man-hole frame; Fig. 2, a plan of the combined curb
any culvert-cover, shewing all parts assembled. Fig. 3 is a section on the
line 3-3, Fig. 2. Figs. 4, 5, 6 and 7 are sectional views upon the same line, but
shewing modified constructions of the curb-rim.
Similar letters of reference indicate corresponding parts in all views of of the
drawings.
The rectangular frame a is adapted to be set into the masonry lining of the
manhole. It is flat on its base and provided with a flange b, projecting on three
sides of the frame at right angles to its base. The flanges b are braced by webs c
and are strengthened by ribs d, extending inwardly. Upon these ribs rests the
The fourth side of the frame a is provided with a flange f, curved to
correspond to the inner curvature of the curb-piece, and dowel-pins r, projecting
from its face engage into corresponding holes of the curb-piece.
cover c.
The curb-piece g is hollow. In the drawings it is shewn curved; but it may be
polygonal. Its top his roughened to prevent slipping. Its back i is vertical, and
its slanting front side k is perforated and protected by rim o on its outmost edge,
against the wheels of vehicles.
Below the rim o is a rib p at the same level as the rib d on the manhole frame.
These ribs support the cover e when the parts are assembled.
Between the flange p and the rim o are three or more holes, in which dowel-
pins on the edge of the cover e, fit.
The open ends u of the curb piece 7 are adapted to receive curbstones or timbers.
Holes s are provided for securing the stones or timbers in place.

page_text: The cover e, fitted into the frame a and to the curved front of the curb, is
strengthened on its lower side by ribs t running radially from its centre, and may
be perforated with holes or slots n¹.
In Fig. 4 the front wall is sloping inward instead of outward. In this case the
protecting rim o is on the upper edge of the front wall. In Fig. 5 the perforated
face n of the curb-rim is receded, and in Fig. 7 the face is vertical and two pro-
tecting rims o and o' are provided. In Fig. 6 the flange f is of different form.
The frame a and cover e may be circular, elliptical, or of other form to suit the
shape of the culvert or manhole. The shape of the curb-piece g may also be
varied to conform to the outlines of the side walks. All parts must, however, in
all cases be fitted together as described above.
The curb and culvert-cover are assembled as follows: First the frame is laid
upon the masonry lining of the manhole. Next the curb is placed thereon,
between the ends of the flange b and the flange f. The dowel-pins r are slid into
the holes of the curb-piece 9, holding it securely in place. Then the curbstones
or timbers are inserted into the ends of curb g, secured therein by screws or bolts
passing through the holes s and, finally the cover e is laid in its place.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A combined sidewalk-curb and culvert cover, comprising a flanged manhole-
frame having the flange on one side separated from the flanges of the adjoining
sides, and provided with dowel-pins projecting therefrom, a cover fitted between
the connected flanges and provided with dowel-pins on its disengaged edge, and a
hollow curb-piece provided with holes for the dowel-pins of the separated flange
of the frame and of the cover, and with end openings for securing to it the curb-
stones on both its ends.
2. The combination of frame a, provided with flanges b and f ribs d and dowel-
pins r, integral with flange f, hollow curb-piece g set upon the frame provided with
holes for the dowel-pins r, and cover e, fitted between the flanges and provided with
dowel-pins to enter holes in the curb-piece, thereby locking the cover and the
curb-piece in position and with the frame.
3. The combination with a manhole-frame having flanges and ribs adapted to
hold a cover in position, one flange being provided with dowel-pins; and with a
cover, fitted upon the ribs of the frame and having one edge provided with
dowel-pins, of a removable curb-piece, fitted between the edge of the cover and the
opposite flange of the frame and provided with holes to receive the dowel-pins pro-
jecting from the flange and from the edge of the cover.
