V construction which is compact and adapted This inventionrelates to a'dry toilet and generally aims to provide a novel inexpensive and improved construction which is odorless,

and fiy-prooi.

A particularobject is to provide a novel construction wherein a draft is created to carry 'ofi odors .into theatmosphere and a for arrangement at a wall of a room. 1

Anotherobject is to provide a construction wherein the seat opening isnormally, closed;

by a fly-excluding member andv which is adapted to be opened by the'pressure of the through the toilet taken at a footof an occupant. v A

The more specific objects and advantages will become apparent froma consideration of; i the description following taken inconnection' v. I with accompanying drawings illustrating an operative embodiment, and wherein :i'

toilet in central vertical transverse section'in connection with partof a, room, Y

Figure 2 is a view showlng the improvements essentially in front elevationbut'part ly broken away andin connection with por tions of the room'structu're shown in section,

Referring specifically to the drawings, the toilet is preferably embodiedrina room as conventionallyshown at 10, the floor being designated 11 and for instance supported by a sill 12 .on masonry .13. Di'sposedrnainly outwardly of the building or room but, ex-

' V tending partly into the same is a casing prefl erably of metal, which is reenforced adjacent;

terminatingin' a nipple 27, onto whichis re charging directly into the atmosphere.

As a result of the construction described,

the atmosphere creates a suction through the v opening 18intermedi'ate the deflectors 23 and 6 a 2 4fand thenceupwardlyrearwardly of the deflector 24 through the passage 26, and duct 1 28, thus removing odors."

: In addition, a shield or closure plate 29 is Pr v d d to normally close the opening 18' 7 against the entrance of flies, such shiel'd or-f closure 29 preferably havinga vent 30 pro- L vided therethrough.
