A New or Improved Appliance adaptable for Sanitary Purposes or
for the Preservation of Perishable Goods.
I, LIONEL DOVE of 3 Westward Ho, Thornhill Road, Leyton, in the
County of Essex, Mechanical Engineer 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 consists, firstly-of a vessel, preferably taking the form, externally,
of an ordinary chamber, or slop pail, the lid of which carries internally a spring,
or clip for holding slips of toilet paper, the rim being arranged to fit within an
annular recess formed in the upper surface of the pail, containing water, oil,
mercury, or other fluid, by means of which a perfect hydraulic joint, or seal is
formed, when the lid is in position upon the pail. A chamber is formed in the
bottom or other part of said pail, in which may be placed any-kind of crystal, or
fluid possessing hygienic, or sanitary properties, for deodorizing or disinfecting the
contents of the pail. The object of this contrivance is that said pail may be used
as a commode, or stool for invalids, or for the use of persons camping out, or
travelling or for medical men conducting post-mortem examinations, and for other
purposes, and when so used and the lid placed thereon, the same may remain in
any convenient spot, or be conveyed to where desired, without the faintest
possibility of noxious gases escaping therefrom, and when the contents is emptied,
the pail may be rinsed, and the lid replaced, and the vessel becomes automatically
disinfected ready for use again at any moment without further preparation.
Secondly-of a modification of the above for use as a vessel for containing and
preserving perishable goods, such as meat, fish, fruits, butter, milk, or the like, and
as a package for conveying the same from place to place. In this case the vessel
may be of any desired shape externally and is provided with an outer jacket, or
casing for the reception and holding of ice, iced water, or other agent, for reducing
the internal temperature of the vessel. The object of this arrangement being that
the contents of said vessel may be kept at a low temperature, insulated from
atmospheric influence, and accompanied by a deodorizing agent, by which means
perishable goods may be kept sweet and good for an almost indefinite period.
In order that the manner of constructing and operating both methods, forming
the subject of my invention, may be clearly understood, I have appended the
accompanying sheet of drawings, in which,
Fig. 1 is a vertical section of said sanitary pail and lid.
Fig. 2 is an external view of said pail partly broken away, and illustrating how
the contents of same may be discharged, without loss occurring to the fluid forming
the hydraulic seal.
Fig. 3 is an enlarged view of the interior of the lid of same, illustrating the
purposes of the spring clip, or toilet paper holder.
Fig. 4 is a plan view of said pail with the lid removed, also shewing an alternative
method of providing a swelling on each side of the upper surface of same,
diametrically opposite to each other, for extending the capacity of the seal, and
preventing the overflow of the fluid therein during the process of emptying the
pail.
Fig. 5 is a part section of said extension, shewing how a finger hold, or handle
may be formed in the bottom of each, when a bail is not used, or for other
purposes.
Fig. 6 is a vertical section of the vessel according to my invention for containing
and preserving perishable goods, arranged for the reception of ice, or its equivalent.
Fig. 7 is an alternative method of constructing Fig. 6, arranged for the reception

page_text: of iced water or its equivalent, finger holds may be formed upon the sides of this
vessel when desired, instead of a bail as in Fig. 6.
Similar letters are employed when referring to like parts, throughout the
drawings.
In carrying my invention into effect, in so far as regards the sanitary vessel for
the use of invalids and for other purposes, I construct of tin, iron, or any other
suitable material, and of any convenient shape, but preferably of that shewn by
Figs. 1 and 2, a containing vessel, pail, or pan A, in some part of which preferably
the bottom, I form a chamber B, provided externally, with a screw inlet plug C, or
its equivalent, for the admission into B of any suitable disinfectant, which may be
fluid, or in the form of soluble salts, or crystals D preferably the latter, as shewn
in the drawings. Upon the upper surface of B (which is the bottom of A) I bore
or otherwise form a central hole a covering which I place a bonnet E, the top of
which is solid as shewn in Fig. 4, the sides being perforated in order that the
disinfectant solution B, may percolate therethrough into A when desired.
Surrounding the top of A, externally, I fix an annular partly covered channel F,
provided with an annular dipping flange b, the space between which, and the
outer wall of A, is sufficient for the reception of the rim c, of the lid G, the depth
of which is slightly less than that of the channel F. Within the channel F, I
place a sufficient quantity of water, oil, mercury, or other fluid, d, to engage with
the lower edge of c, when G is placed in position covering A, and so form an
hydraulic joint, or seal, which effectually prevents any escape of noxious gas, or
vapour that may exist in, or be generated by the contents of A. Within the
upper surface of A I fix a wire or other rim e, and upon this rests a portable
wooden, or vulcanite rim f, tapered internally to form, and be used as, the top of
an ordinary commode or w.c. The lid, or cover G, is furnished, internally, with a
spring clip g, or its equivalent, for holding a small quantity of toilet papers glor
for other purposes, and externally with a ring or handle h. The vessel may be
furnished with a bail or handle H, by which it may be carried. Or I may in
certain cases for the duplex purpose of dispensing with H, and increasing the area
of F, or for the latter purpose alone, without dispensing with H, form extensions
or swellings F, upon and within F, the under surfaces of which may be shaped to
form finger holds, as at Fig. 5, so that the vessel may be carried thereby, instead
of H, if desired. The manner of operation is as follows.
The deodorizing salts, or crystals D being placed in B, through C, as described
and shewn, and the necessary quantity of water, oil, mercury, or other fluid placed
in F, the pail or pan is ready for use. When the said pail, or pan is to be used as
a commode, or stool, a small quantity of water would be placed in A, which
passing through the perforations in E, would enter B, and partly dissolve the
deodorizing agent D, and by this means the vessel becomes disinfected before use,
and after being used by the patient, or other person, the lid G, would be placed
thereon, and the contents thereby perfectly sealed. When the vessel is to be
emptied the lid G, would be removed, and the vessel tilted in the usual way. The
fluid d in F, forming the seal, would then flow around the upper surface of A, as
shewn in Fig. 2, and at the same moment a small quantity of the deodorizing agent
in solution would percolate through E, so that when the vessel is again placed in a
vertical position, a small quantity of said disinfectant would remain in the bottom
of A, to the height of the neck of E, or the lowest row of perforations, and by
this means the vessel is disinfected ready for use again, when needed. The vessel
may if needed be rinsed before placing aside after using, and a small quantity of
water placed therein as in the first instance, to keep the deodorizing agent always
in solution.
I have previously mentioned that I may in certain cases, form an extension,
or swelling F, upon and within F, to further insure the non-possibility of the seal
liquid d, overflowing, when the pail, or pan is inverted, or partly inverted, as in
Fig. 2, and I may here mention that to further insure the attainment of the same
object, I may swage, or otherwise form an annular swelling, or projection upon the

page_text: outer surface of F, or in any other suitable way extend, or enlarge the internal
capacity of F, for the same purpose, and to attain this end.
By the foregoing description of the pan, pail or other vessel, it will be understood
that by a slight modification of the design, or the manner of operation, the same
may be employed for any, and all of the purposes named, and so form a perfect and
reliable safeguard against the spread of infectious diseases arising through the
inhalation of noxious gases, or vapours, that may be generated by, or exist in, the
post mortem, or other contents of the vessel when in use.
In carrying my invention into use as a vessel for containing, or for containing
and conveying perishable goods, with the exception of the outer conformation of
the vessel, I employ substantially the same means as that just described, that is to
say, a similar lid (less the spring or clip 9) engages in a like manner within, and
with a similar annular recess in the upper surface of the vessel, containing fluid
and forming an hydraulic seal as before, also a similar chamber B, containing a
deodorizing agent D, and provided with a perforated bonnet E is formed therein
and preferably at the bottom thereof as shewn.
In this arrangement, I construct of any suitable metal or material, and of any
shape or design desired, externally, but preferably as shewn at Figs. 6, and 7, a
vessel A, which, when intended to receive ice or its equivalent as a cooling agent,
may be provided with an internal wall I, connected to the bottom thereof, and
extending upwards for about half the height of A, and within the chamber thus
formed between A, and I, the ice J or its equivalent may be placed, a bottomless
bell, or other shaped vessel K, is arranged to fit within J, and closely against the
inner surface of the annular seal F, thereby enclosing the ice chamber, as in Fig. 6,
a perforated tray L, resting upon a ridge i, receives the goods to be preserved,
which may be piled thereon to the full of the vessel if needed, and the lid placed
thereon as in the previous method, the same method as before described being
employed for operating the deodorizing agent. The vessel may be provided with
a bail, or handle H, to facilitate its removal from place to place, and an outlet
plug m, for the removal of the ice I, when melted.
When said vessel is intended to contain iced water or other agent for reducing
the internal temperature instead of ice, the wall I, may be carried up to the top
of A, and form the inner surface of F, as in Fig. 7. In this case an inlet plug M
is provided for the admission of the iced water or its equivalent J', between I, and A,
and 1 may provide suitable finger holds upon the outside of A. in lieu of the bail,
or handle H.
By means of a vessel constructed either as at Fig. 6, or 7, and in the manner
described, I am enabled to store, and convey perishable goods, from place to place,
and keep the same cool, deodorized, sweet, and good, for almost an indefinite
period.
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 I
claim is.
1st. The appliances herein described and shewn, for use as a sanitary vessel for the
convenience of invalids or travellers, or medical men while performing post mortem
examinations. Or as a containing vessel for holding, conveying and preserving
perishable goods, consisting of the several parts enumerated, constructed, combined
and operating substantially as herein set forth, and for the purposes specified.
2nd. In an improved sanitary appliance, the construction and use of a pan, or
pail A, provided with a chamber or its equivalent and perforated bonnet E,
containing any kind of deodorizing agent D. The annular channel, or groove F,
with dipping flange b, containing and holding water, oil, mercury, or other fluid d,
forming an hydraulic joint, or seal with the rim c, of a lid G, provided with an
internal clip, or spring g. The ledge e, for receiving and holding a portable rim f,
for use as a w.c. seat by invalids, or others, substantially as described and shewn
by Figs. 1 2, 3 and 4 of the accompanying drawings.

page_text: 3rd. The manner of arranging and constructing the chamber B or its equivalent
and annular recess F, mentioned in the preceding claim, with, or without the
extension F', so that during the process of emptying the pan, or pail A, the former
may automatically disinfect the same, and the latter retain its fluid contents for
again forming a seal, or vapour tight joint with the lid G, when A is brought to
a vertical position, substantially as described and shewn by the accompanying
drawings.
4th. In an improved appliance for the conveyance and preservation of perishable
goods, the employment of a chamber B or its equivalent and its contents, the annular
recess F, and its contents, operating as set forth in the foregoing claims, in com-
bination with a vessel A, provided with an internal wall or partition I, for the
reception of ice, or iced water or other agent J for reducing internal temperature.
