IMPROVEMENTS IN OR APPLICABLE TO WATER CLOSETS AND URINALS
Year: 1884

page_text: I, DANIEL THOMAS BOSTEL, at the Office for Patents, 17 and 18, Southampton
Buildings, in the county of Middlesex, Sanitary Engineer, do hereby declare the
nature of my invention for "IMPROVEMENTS IN OR APPLICABLE TO WATER CLOSETS
AND URINALS," to be as follows:-
This invention has for its object further improvements on the water closet or
urinal for which I obtained Letters Patent dated the 11th day of October 1880,
No 4126.
By my invention I propose to still further increase the efficacy of such closets
or urinals by giving a more equal and powerful flush for cleansing the same.
According to my present invention I fit a pipe, vessel, or cylinder to the supply
arm of the closet or urinal, the said pipe, vessel, or cylinder being closed at its top
and open to the supply arm at its bottom.
Within this pipe, vessel, or cylinder I arrange a stand-pipe open at its top end
but with its lower end secured to the curved spout or arm claimed in my former
specification and by means of which the water or flushing medium has direct and
unobstructed passage to the contents of the basin.
When water is admitted from a cistern or otherwise to the supply arm of the
closet or urinal it rises in the closed pipe, vessel, or cylinder compressing the air
therein till it reaches a point when the water is driven by pressure into the stand-
pipe and rushes down the curved spout or arm directly to the contents of the basin,
with uninterrupted and powerful flush, driving the said contents over the lip of
the closet as described in the said specification.
Water is at the same time directed by the supply arm to the scroll for washing
the sides of the basin.
The apparatus is preferably made of metal and can be secured to the brass
connecting pieces secured to the earthenware of the closet by studs fixed to the
exterior of the apparatus, fitting concentric grooves in the said connecting pieces,
the said grooves having short extensions into which the studs enter when turned
and so lock the apparatus to the connecting pieces, being further secured by lock
nuts.

page_text: I DANIEL THOMAS BOSTEL at the office for Patents 17 and 18 Southampton
Buildings in the county of Middlesex, Sanitary Engineer, do hereby declare the
nature of my invention for IMPROVEMENTS IN OR APPLICABLE TO WATER CLOSETS
AND URINALS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has for its object further improvements on the water closet or
urinal for which I obtained Letters Patent dated the 11th day of October 1880
No. 4126.
By my invention
propose to still further increase the efficacy of such closets
or urinals by giving a more equal and powerful flush for cleansing the same.
According to my present invention I fit a pipe vessel or cylinder to the supply
arm of the closet or urinal, the said pipe, vessel or cylinder being closed at its top
and open to the supply arm at its bottom.
Within this pipe vessel or cylinder I arrange a standpipe open at its top end
but with its lower end secured to the curved spout or arm claimed in my former
specification and by means of which the water or flushing mediuin has direct and
unobstructed passage to the contents of the basin.
When water is admitted from a cistern or otherwise to the supply arm of the
closet or urinal it rises in the closed pipe, vessel or cylinder compressing the air
therein till it reaches a point when the water is driven by pressure into the stand
pipe and rushes down the curved spout or arm directly to the contents of the basin
with uninterrupted and powerful flush driving the said contents over the lip of
the closet as described in the said specification.
Water is at the same time directed by the supply arm to the scroll for washing
the sides of the basin.
The apparatus is preferably made of metal and can be secured to the brass
connecting pieces secured to the earthenware of the closet by studs fixed to the
exterior of the apparatus fitting concentric grooves in the said connecting pieces,
the said grooves having short extensions into which the studs enter when turned
and so lock the apparatus to the connecting pieces, being further secured by lock-
nuts.
In order that my invention may be understood and carried into practical effect
I have caused to be annexed to this specification the accompanying sheet of
drawings and now refer to the figures and letters of reference marked thereon.
Fig 1. is a side elevation (half being shewn in vertical section) of my improve-
ments adapted to a closet described in my former letters patent.
Fig 2. is a front view drawn in section through the closet pan, the improvements
being shewn in elevation.
Referring to my former specification A is the receptacle or basin A' the scroll or
hollow rim supplying water or flushing material to flush the sides of the basin
B the supply pipe or arm to this scroll C the spout or arin directing the main body
of water or flushing material. F the forcing shaft or trunk G the trap. D is the
cylinder before referred to closed at its top and with the standpipe E rising in the
same.

page_text: The cylinder D is closed at its bottom by the stand pipe E being soldered or
fitted into the same.
The cylinder D has an arm B¹ fitted to the supply arm B supplying the scroll A'
and the standpipe E has an arm C¹ connected to the arm or spout C. H is the
pipe from the flushing tank, cistern or valve on the source of supply. This pipe
admits water to the cylinder D in which it rises compressing the air in the bell or
top of the same, this drives the main body of water or flushing material with cop-
siderable force down the stand pipe E through the arm C thus driving out the
contents of the closet or urinal; at the same time the scroll A¹ is supplied from the
cylinder D.
As shewn I have made the connection between the apparatus and the closet by
a rubber or elastic sleeve I. over the scroll connection B, being suitably clamped
by wire, and I have shewn the connection at C by means of bolts and a rubber or
elastic washer, but I can arrange both connections as before described in the same
plane to be locked by grooves and studs fitting the same, a device well known to
mechanics and for which I make no claim.
Other suitable or expedient means may be used for the purpose.
It will be apparent to any practical plumber, sanitary engineer or other person
understanding sanitary matters that my improved apparatus can be adapted to
other systems of closets or urinals in which a powerful flush of water or flushing
material is desired besides the typo of closets before mentioned.
And in those closets where no flushing scroll or rim is used the standpipe E may
wholly flush the closet or urinal or a passage or port from the cylinder D may be
otherwise directed on, round or into the basin or receptacle.
The closet or urinal can have brass or other metal connecting pieces on the
arms B. C. or the same be formed in one piece with the closet which may be in
metal pottery or other suitable material.
The apparatus D. E. can be made of lead, zinc, brass or other suitable metal or
material.
•
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 what
I claim is
1st Applying to water closets and urinals a closed chamber or cylinder (such
as D) having a stand pipe (such as E) fitted therewith arranged so that water or
flushing liquid admitted to the said closed chamber or cylinder may by the com-
pression of air in the same be driven forcibly out from the said stand pipe and
cylinder to the basin or receptacle as and for the purposes described.
2nd The closed chamber or cylinder D fitted with the standpipe E and with
arms B¹ C¹ for supplying the flushing scroll or rim and main flushing arm of a
closet or urinal substantially as described.
