Improvements in or relating to Closets.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent 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 :-
The present invention relates to that class of closet in which the cover of the
seat is used for effecting the closure. This object however cannot be attained by
simply fitting the cover on the seat because even with the most careful joiner's
work the case of the pan forming the seat is not tightened against the latter nor is
it air-tight itself.
According to the present invention the basin is tightened against the seat by a
flange and the cover against the seat; the flange however may penetrate the
aperture of the seat so that the cover can be tightened directly against the flange.
In both these cases the cover is provided on its bottom side with a tightening ring
and is pressed against the seat-board or against the flange by its own weight or by
suitable mechanism. This tightening of the pan and the cover forms the first part
of the invention, the second part of which may be formed by a special arrangement
of the locking mechanism. This mechanism may be arranged in such a manner
that in locking it no unaccustomed operation will be necessary as it may be done
automatically. By this means the is covered in after each use of the closet.
pan
The invention is represented on the accompanying drawing in which
Figure 1 is a transverse section, Figure 2 is a plan view, Figure 3 a cross section
and Figures 4 and 5 show in a larger scale the locking lever.
In the construction shown in Figures 1 and 2 the upper rim of the pan a is
surrounded by a flange b which is tightly cemented thereon. This flange bis
provided with an upwardly projecting flange b₁ fitting into the aperature of the
seat. In place of this flange a separate ring could be provided or formed
together with the pan. In the construction shown in Figure 3 the ring b¹ is bent
over the upper side of the seat, so that a direct tightening of the cover against the
pan is obtained; d is the usual cover hinged to the seat board; e is the tightening
ring of indiarubber or other suitable material and which is fastened to the bottom
side of the cover; this ring surrounds the aperture of the seat and effects the
tightening between cover and seat.
The special mechanism for locking the cover as mentioned above cousists of a
rod or shaft pivotted upon the cover and carrying on its two ends hooks 9. These
hooks are capable of entering eyes such as h shown in Figures 1 and 2 fastened to
or formed with the flange baud fitted in suitable recesses of the seat; these eyes
are formed in the construction shown in Figure 3 by cross-bars which are laid
over the recesses of and fastened to the seat. This combination is shown on an
enlarged scale in Figures and 5. The surface of the hook which engages the
eyes or is eccentric to the axis fas most clearly shown in Figure 5 and the
result of which is that when the hooks enter the eyes a tightening of the cover
against the seat takes place.
The cover is locked by the handle i which is secured to the rod or shaft f and
has a lug k which bears against the cover when being opened. Supposing the
closet be closed as shown in Figures 1 to 3 the hooks may be disengaged from the
eyes, when the lever i is raised; after this, when raising the lever i further
upwards, the lug k bears against the cover d which now follows the lever in its
movement.

page_text: When the cover is to be closed the lever i is lowered and the cover falls by its
own weight upon the seat, in the further downward movement of the lever the
hooks 9 engage the eyes and the cover is tightened against the seat c. If the lever
is sufficiently heavy the tightening of the cover may be done automatically by the
weight of this lever.
This locking device may, as will be well understood, be modified without
departure from the spirit of the invention.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed, I declare that what I claim is,-
s
1. The combination with the pan a of a cover d having a ring such as e
substantially as described and illustrated in the accompanying drawings.
2. An air-tight closure for closet pans characterized by the pan a being tightened
against the seat or the cover d against a flange 66' and provided on its bottom face
with a tightening ring such as e substantially as described and illustrated in the
accompanying drawings.
3. The mechanism for pressing the cover d when closed against the seat or
against the part b¹ of the flange & fitted in the seat aperture consisting of a lever i
pivotted upon the cover the shaft f of which is provided with hooks g engaging
with eyes such as h or h¹ substantially as described and illustrated in the accom-
panying drawings.
