Year: 1885

page_text: I EDWARD MORRIS of Sherbourne Street Galvanizing Works Birmingham in the
County of Warwick Brazier and Iron Plate Worker do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN SANITARY PANS AND OTHER LIKE
PANS" to be as follows:-
My invention has reference to the lids or covers of sanitary pans and other like
pans and to the production of a liquid and air tight joint between the lids or
covers and the bodies of the said pans and my said invention consists in construct-
ing the said lids or covers and the parts of the bodies of the pans on which they
seat themselves in the manner herein after described.
In order to give increased strength and rigidity to the flat lids or covers of
sanitary and other pans I form in the said lids or covers by stamping two or more
concentric corrugations and also form at the centre of the lid a raised part or seat
on which the middle of the crossing inverted bow spring for fastening the lid to the
body of the pan is rivetted. I also corrugate or give to the marginal part of
the lid or cover a convex figure. This marginal corrugation besides increasing the
rigidity and strength of the lid also produces a trough shaped depression on the
underside of the lid into which depression the india rubber ring on the said lid is
forced when the lid is pressed homie upon the top of the pan In addition to the
strong hoop on the outside of the pan and near the top thereof for the jointed
catches of the fastening spring to engage under I make above the said hoop and
preferably in one piece with it a beading having a semi-circular figure in cross
section.
When the combined beading and hoop is fastened flat side inwards by brazing
and rivetting to the outside of the top of the pan the said beading forms at the
edge of the pan a broad seat on which the india rubber ring on the underside of the
lid or cover seats itself.
On the lid or cover being pressed to its seat by the act of fastening it in its place
the flat india rubber ring on its underside is forced into the depression at the
marginal part of the lid or cover.
The figure which is thus given to the india rubber ring causes its edge to
embrace or spread over and take a close fit against the convex beading or seat on
the top edge of the pan. A very perfect liquid and air tight joint between the
cover and top is thereby produced.

I EDWARD MORRIS of Sherbourne Street Galvanizing Works, Birmingham in
the County of Warwick, Brazier and Iron Plate Worker, 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 :-
My invention has reference to the lids or covers of sanitary pans and other like
pans and to the production of a liquid and air tight joint between the lids or
covers and the bodies of the said pans; and my said invention consists in con-
structing the said lids or covers and the parts of the bodies of the pans on which
they seat themselves in the manner hereinafter described.
In order to give increased strength and rigidity to the flat lids or covers of
'sanitary and other pans I form in the said lids or covers by stamping, two or more
concentric corrugations and also form at the centre of the lid a raised part or seat
on which the middle of the crossing inverted bow spring for fastening the lid to
the body of the pan is rivetted. I also corrugate or give to the marginal part of
the lid or cover a convex figure. This marginal corrugation besides increasing the
rigidity and strength of the lid also produces a trough shaped depression on the
underside of the lid into which depression the india rubber ring on the said lid is
forced when the lid is pressed home upon the top of the pan. In addition to the
strong hoop on the outside of the pan and near the top thereof for the jointed
catches of the fastening spring to engage under, I make above the said hoop and
preferably in one piece with it a beading having a semi circular figure in cross
section. When the combined beading and hoop is fastened flat side inwards by
brazing and riveting to the outside of the top of the pan, the said beading forms at
the edge of the pan a broad seat on which the india rubber ring on the underside
of the lid or cover seats itself.
On the lid or cover being pressed to its seat by the act of fastening it in its
place, the flat india rubber ring on its underside is forced into the depression at the
marginal part of the lid or cover.
The figure which is thus given to the india rubber ring causes its edge to
embrace or spread over and take a close fit against the convex beading or seat on
the top edge of the pan. A very perfect liquid and air tight joint between the
cover and top of the pan is thereby produced.
Figure 1 of the accompanying Drawing represents partly in elevation and partly
in vertical section a sanitary pan containing my improvements; Figure 2, represents
a section of the lid or cover detached from the pan and Figure 3 represents a
portion of the lid or cover in plan; Figures 4 and 5 represent in section the body
of the pan drawn to a larger scale than Figures 1. 2 and 3, the said Figures 4 and 5
exhibiting the combined beading and hoop.
The same letters of reference indicate the same parts in the several Figures of the
drawing.
a is the body of the pan and b is the lid or cover having on the underside
of its marginal part the strong india rubber ring c. On the upper side of the said

page_text: lid the crossing inverted bow spring d is situated, the said spring having at its ends
jointed hook ended catches d³, d for fastening the lid or cover to the body of the
pan, the said hook ended catches d³, d' engaging under the hoop on the said body
of the pan as hereinafter described. The middle of the bow spring d is supported
on the raised part or seat e at the middle of the lid the said bow spring being kept
in its place by the cross strap f rivetted on the lid, a pin on the bow spring
engaging in a small socket in the strap f; g, g are concentric corrugations made in
the flat cover b for increasing its strength and rigidity. The marginal part of the
lid or cover b is made convex or corrugated at h. The marginal corrugation h forms
on the underside of the lid b a trough shaped depression into which the india
rubber ring c is forced when the lid is pressed home upon the top of the pan. The
seat e corrugations g, g and the marginal corrugation or depression h are made in
the flat lid 6 by stamping.
On the outside of the pan and near the top thereof the combined beading and
hoop is rivetted or otherwise fastened. The beading is marked i and the hoop is
marked k in the Drawing. The said beading is nearly semi-circular in cross
section as best seen in the enlarged views Figures 4 and 5 and the said beading
forms at the edge of the pan a broad seat on which the india rubber ring c on the
underside of the lid or cover b seats itself as hereinafter described. The bottom
edge of the hoop k may either be inclined or V shaped as represented in Figures 1
and 4 for the hook ended catches d², d of the bow spring d to engage under or the
bottom edge of the said hoop k may be flat or horizontal for the said hook ended
catches d², d to engage under as represented in Figure 5. I prefer however to
make the bottom of the hoop in the manner represented in Figures 1 and 4 as the
catches have a better hold upon this form of hoop than upon hoops having flat
bottoms and the risk of the disengagement of the catches from the hoop by the
rough treatment to which the pans may be subjected in use is prevented.
In order to fasten the lid or cover b to and force it upon its seat on the top of
the pan a the said lid or cover is placed on the top of the pan and the ends of the
bow spring d are depressed so as to enable the hook ended catches d³, d³ to engage
under the bottom edge of the hoop k as represented in Figure 1. As the lid
or cover b is pressed to its seat by the act of fastening it in its place the edge of
the nearly flat india rubber ring c (see Figure 2) is forced into the depression h at
the marginal part of the lid or cover b as seen in Figure 1 and the edge of the said
ring c is made to embrace or spread over the convex beading i on the top of the
pan. A very perfect liquid and air tight joint between the cover and the top. of
the pan is thereby formed.
Although I prefer to make the combined convex beading i and hoop k in one
piece as represented yet the said beading i and hoop k may be made separately and
connected to the pan in the relative positions shown with respect to the beading
and hoop in one piece; and although my improvements are especially applicable to
sanitary pans yet they may also be applied to other pans for containing refuse
matters such for example as wash, as well as to pans generally which it is
desirable to close air and water tight for any purpose.
Having now particularly described and ascertained. the nature of my said
invention and in what manner the same is to be performed I declare that
I claim as my invention of "Improvements in sanitary pans and other like pans
"
First. Fixing around the top edge and on the outerside of the pan a convex
beading or seat made preferably in one piece with the hoop under the bottom edge
of which the catches of the fastening bow spring carried by the lid or cover engage
for the purpose of producing a liquid and air tight joint between the lid or cover
and the top of the pan substantially as herein before described and illustrated in
the accompanying Drawing.
Secondly. Making at the marginal part of the lid or cover a corrugation or
5 trough shaped depression into which the edge of the india rubber ring on the

page_text: underside of the lid or cover is forced when the said lid or cover is pressed to its
seat on the pan for the purpose and substantially as herein before described and
illustrated in the accompanying Drawing.
Lastly Connecting the crossing inverted bow spring by which the lid or cover
is fastened down to a raised part or seat at the middle of the lid or cover as herein
before described and illustrated in the accompanying Drawing.
Dated this First day of March 1886.
