We GEORGE HENRY JENNINGS and SIDNEY JENNINGS, of Palace Wharf, Stangate,
in the County of Surrey, Sanitary Engineers, 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 :—
This Invention relates to further improvements on our former invention for
which we obtained Her Majesty's Letters Patent No. 4796, A.D. 1881, and has
for its object to provide an improved device or bush for more securely fixing and
strengthening the trunnions of tipping basins.
And in order that our said invention may be better understood we now proceed
to describe the same with reference to the accompanying drawings in which Figure 1
is a front elevation shewing the bush fitted to one side of a basin, and Figure 2
a cross section on line X X of Figure 1.
S is a portion of one side of a basin and A' A¹ a boss or enlargement moulded
upon each side of the said basin and enclosing circular recesses B₁ into which is
fixed the improved device or bush A.
The inner periphery of the recess B₁ is undercut or chamfered inwardly, as
shewn in Figure 2, leaving a space B¹ and the opening C between the outer
periphery of the device or bush A and the said recess, into which liquid sulphur
or other suitable material is poured in order to secure the device or bush
permanently in position.
This said device or bush A, which is of brass, gun metal, phosphur bronze, or
other suitable material, is formed with the central trunnion B resting in the U shape
bearings I provided for the purpose of supporting the basin, and arranged with the
outer wall or flange F which revolves around the U shape bearing I, thereby
protecting the porcelain boss A' from risk of injury. The wall or flange F does
not extend all round the bush but has the bottom segment of the periphery slotted
so as to allow the basin to be readily lifted out and removed when in a horizontal
position.

page_text: The device or bush A is also formed with a central groove around its outer
periphery and when it is desired to fix the bush in position, the same is placed
in the circular recess B¹ in the position shewn, and sulphur is poured in at C and
runs all round the periphery of the bush between the latter and the inner periphery
of the recess, thus firmly securing it in position and forming a tight joint.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved device or bush for fixing the trunnions of tipping basins used in
lavatories and for other sanitary purposes substantially as and for purpose described
and shewn in the accompanying sheet of drawings.
