Improvements in Metal Tanks, Cisterns, Troughs, Water-cart Bodies,
Cylinders, Corn-bins, Dust-bins, and similar Articles, and in the
Construction thereof.
I ROBERT CHARLES JAY of 41, Saint Luke's Road, Westbourne Park, in the
County of Middlesex, and of the Middle Temple, Barrister-at-Law, do hereby declare
the nature of my said invention to be as follows:-
The object of this Invention is to produce greater strength and rigidity and also in
the case of close Tanks, Cylinders, and similar articles to produce a manhole, hand-
hole, or other hole and cover that may be simply constructed easily opened or closed
and at the same time reliable for making a good joint.
The first part of my Invention consists in placing a frame of angle flat or other
suitable section of metal internally round the top of open Cisterns Troughs Corn-Bins
Dust-Bins or other similar articles and rounding off the corners of the said frame
instead of making or welding it at an angle and I make good the space at the corners
between the sides of the aforesaid cisterns or other articles and the aforesaid
frame by means of corner plates having the sides turned down so that they
may be rivetted to the sides of the aforesaid cisterns and the said corner
plates may be rivetted to the frame in the usual manner or when an angle
frame is employed by passing the rivets through oblong holes so constructed as to
allow the rivets to play when the frame is expanded or contracted by straightening or
bending the aforesaid rounded corners.
A further part of my Invention consists in strengthening the flat surfaces of Cisterns
Tanks or other similar articles and to carry this out I rivet on sheet iron or steel bent
or corrugated with one or more flutes or corrugations with or without a flange turned
off on one or both sides and in some cases I connect two of the aforesaid strengthening
pieces by means of stays or tie bars.
Another part of my Invention applies more particularly to close Tanks and
Cylinders and to such articles as are usually fitted with manholes or handholes and
consists in the formation and construction of the manhole and of the cover for closing
the same and for this purpose I employ a bridge on the outside constructed with two
or more arms or ribs and having a hole in the centre with a screw bolt provided with
one or more nuts the said cover and bolt being provided with a hook and eye or other
suitable arrangement so that they may be connected or disconnected as required and
so as to form a flexible joint between the aforesaid cover and the aforesaid bolt the
aforesaid arms being surrounded by a frame having a flat face of sufficient depth to
give the necessary strength and preferably in the form of an angle or tee so as to give
the greatest amount of strength with the least weight of metal the said frame being
larger in its dimensions than the manhole for which it is to be employed and corre-
sponding with a cover placed on the inner side of the aforesaid manhole.
cases the aforesaid bolt may be firmly fixed to the cover and I employ clips to hold up
the cover while the bridge is being attached thereto. When the manhole is circular
that is to say one dimension is not longer than another so as to enable the cover to be
passed through I place the said cover inside the Tank before it is rivetted up. The
edge of the plate formning the manhole may be left fat or it may be turned over either
upwards or downwards so as to form a rim all round the manhole to strengthen it and
when turned downwards it may be employed to receive a suitable packing for which
purpose I prefer indiarubber or other suitable clastic composition having a circular
section with a hole through the centre similar to a tube but any other suitable packing
may be employed.
In some
In some cases I place the cover on the outside of the tank or other article and the
bridge on the inside and in the case of circular manholes I place the bridge inside the

page_text: tank before rivetting it up and I employ clips to hold it up while the cover is being
put on. I attach the contral bolt aud nut to the bridge by means of a hook formed at
one end of the said bolt fitting into an eye fixed to or formed on the aforesaid bridge
and I leave the edge of the plate forming the manhole flat or turn it over so as to
strengthen it and when it is turned upwards I also employ it to receive the packing
ring. In the centre of the cover I form a boss having a hole the outer portion of the
said hole being opened out so as to receive a packing ring and forming an angle or
narrowing recess with the aforesaid hooked screw bolt which passes through the afore-
said hole and is provided with a nut and washer or in the place of the aforesaid boss
I employ a washer with the underside hollowed or cut out in a similar manner the
said hollowing out causing the packing to make a tight joint between the cover and
the aforesaid bolt when the nut is screwed down.
When the hole to be closed is small I dispense with the aforesaid bridge and screw
the said bolt which passes through the centre of the cover and is provided with a
hollow washer as described directly into the hole.
The aforesaid bridge and cover or either of them may be made of wrought or cast.
iron or steel or other suitable metal or a combination thereof and the frame of the
aforesaid bridge may be provided with arms or a cast or wrought plate or dish may
be employed in the place of the aforesaid arms. The bridge or cover before described
may in some instances be fitted with two or more bolts and nuts but in small man-
holes one is sufficient.
The corner-plates as described in the first part of my invention may be attached to
the angle iron frame by means of rivets as before described or they may be so attached
by bending the edge of the aforesaid corner-plates over the edge of the aforesaid angle
iron frame with or without the said rivets.

Improvements in Metal Tanks, Cisterns, Trough Water-cart Bodies,
Cylinders, Corn-bins, Dust-bins, and similarrticles, and in the
Construction thereof.
I ROBERT CHARLES JAY of 41, Saint Luke's Road, Westbourne Park, in the
County of Middlesex, Barrister-at-Law, do hereby declare the nature of my said inven-
tion 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 this Invention is to produce greater strength and rigidity and also in
the case of Close Tanks and Cylinders and similar articles to produce a Manhole,
Handhole or other hole and cover that may be simply constructed, easily opened or
closed and at the same time reliable for making a good joint.
The first part of my Invention consists in placing a frame of angle flat or other
suitable section of metal internally round the top of open Cisterns, Troughs, Corn-
Bins, Dust-Bins or other similar articles and rounding off the corners of the said frame
instead of making or welding it at an angle and I make good the space at the corners
between the sides of the aforesaid cisterns or other articles and the aforesaid frame by
means of corner plates having the sides turned down so that they may be rivetted to
the sides of the aforesaid cisterns. and the said corner plates may be rivetted to the
frame in the usual manner or where an angle frame is employed by passing the rivets
through oblong holes so constructed as to allow the rivets to play when the
frame is expanded or contracted by straightening or bending the aforesaid rounded
corners.
A further part of my Invention consists in strengthening the flat surfaces of
Cisterns, Tanks, or other similar articles, and to carry this out I rivet on Sheet
iron or steel bent or corrugated with one or more flutes or corrugations with or
without a flange turned off on one or both sides and in some cases I connect two
of the aforesaid strengthening pieces by means of stays or tie-bars.
Another part of my Invention applies more particularly to Close Tanks and
+

page_text: Cylinders and to such articles as are usually fitted with Manholes or Handholes
and consists in the formation and construction of the manhole and the cover for
closing the sames and for this purpose I employ a bridge on the outside constructed
with two or more arms or ribs and having a hole in the centre with a screw-
bolt provided with one or more nuts the said cover and bolt being provided with.
a hook and eye or other suitable arrangement so that they may be connected or
disconnected as required and so as to form a flexible joint between the aforesaid
cover and the aforesaid bolt the aforesaid arms being surrounded by a frame
having a flat face of sufficient depth to give the necessary strength and preferably
in the form of an angle or tee iron so as to give the greater amount of strength
with the least weight of metal the said frame being larger in its dimensions than
the manhole for which it is to be employed and corresponding with a
placed on the inner side of the aforesaid manhole. In some cases the aforesaid
bolt may be firmly fixed to the cover and 1 employ clips to hold up the cover
while the bridge is being attached thereto. When the uianhole is circular that is
to say one dimension is not longer than another so as to enable the cover to be
passed through I place the said cover inside the Tank before it is rivetted up.
The edge of the plate forming the manhole may be left flat or it may be turned
over either upwards or downwards so as to form a rim all round the manhole to
strengthen it and when turned downwards it may be employed to receive a suit-
able packing for which I prefer indiarubber or other suitable elastic composition
having a circular section with a hole through the centre similar to a tube but
any other suitable packing may be employed.
cover
In some cases I place the cover on the outside of the Tank or other article and
the bridge on the inside and in the case of circular manholes I place the bridge
inside the Tank before rivetting it up and I employ clips to hold it up while the
cover is being put on. I attach the central bolt and nut to the bridge by means
of a hook formed at one end of the said bolt fitting into an eye fixed to or
formed on the aforesaid bridge and I leave the edge of the plate forming the
manhole flat or turn it over so as to strengthen it and when it is turned upwards
I also employ it to receive the packing ring. In the centre of the cover I form
a boss having a hole the outer portion of the said hole being opened out so as to
receive a packing ring and forming an angle or narrowing recess with the afore-
said hooked screw-bolt which passes through the aforesaid hole and is provided
with a nut and washer or in place of the aforesaid boss 1 employ a washer with
the underside hollowed or cut out in a similar manner the said hollowing out
causing the packing to make a tight joint between the cover and the aforesaid
bolt when the nut is screwed down.
When the hole to be closed is small I dispense with the aforesaid bridge and
screw the aforesaid bolt which passes through the centre of the cover and is pro-
vided with a hollow washer as before described, direct into the hole.
The aforesaid bridge and cover or either of them may be made of wrought or
cast iron or steel or other suitable metal or a combination thereof and the frame
of the aforesaid bridge may be provided with arms or a cast or wrought plate or
dish may be employed in the place of the aforesaid arms. The bridges or covers
before described may in some instances be fitted with two or more bolts and nuts
but in small manholes one is sufficient.
The corner plates as described in the first part of my Invention may be attached
to the angle iron frane by means of rivets as before described or they may be attached
by bending the edge of the aforesaid corner plates over the edge of the before-
mentioned angle iron frame either with or without the said rivets.
In order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
annexed Sheet of Drawings.
Figure 1. represents a corner of an angle iron frame for open cisterns and
other similar articles showing the manner in which it is bent round so as to avoid
weakning the iron as is the case where welding is employed.

page_text: Figure 2. shows a corner plate having the sides bent down so as to pass between
the angle frame and the sides of the cistern.
Figures 3-4 a a a represent fluted strengthening plates in section of different
patterns which rivet on the flat surfaces bb of Tanks or Cisterns when they
require stiffening.
Figure 5. is a section of a manhole and bridge cover showing the various parts
whereof c c is the bridge provided with arms d d bearing on a flat surface e e in the
form of the manhole and having a boss and clearing hole in the centre for the screwed
hook-bolt with a nut and washer g. hh show the plate forming the edge of the
manhole and the manner in which it is turned over. i i represent an indiarubber
packing ring having a hollow core so as to make it more pliable. jj is the cover
provided with a loop or eye and clip or clips kk so constructed that they rest upon
the edge of the manhole in recesses I provided for that purpose in the rim of the
bridge
ee and hold up the cover while the bridge c c is being adjusted..
Figure 6. is a modification of Figure 5. and is similar in every way except that the
packing is solid instead of hollow.
Figure 7. is a further modification of Figure 5. showing the manner in which the
cover jj is fitted on the outside of Tanks the bridge cc being then on the inside a
washer m hollowed out on the underside and having a packing ring n round the bolt
being employed to make the joint tight between the cover e c and the bolt f which is
shown straight but may be hooked and fitted as shown in Figures 5. 6 and 9. if
preferred.
Figure 8. represents another modification of Figures 5. 6 and 7 and is similar in
every respect to Figure 7. except that a boss o hollowed out to receive a packing
ring n is fitted or made on the cover jj and a flat packing ring p p is employed to
make the joint.
Figure 9. represents the screwed hook-bolt f before mentioned.
In figures 3. and 4. similar letters denote similar parts.
In figures 5. 6. 7 and 8. similar letters denote similar parts.
