IMPROVEMENTS IN TIP WAGGONS
Year: 1885

page_text: I, PERCIVAL FOWLER, of Queen Square Place in the City of Westminster, Civil
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN
TIP WAGGONS" to be as follows:-
My invention relates to the waggons used upon railways, and known as tip
waggons, in which the body of the waggon forms a receptacle for earth or other
material to be removed and is pivotted upon a transverse pivot near the centre of
its length, which pivot is itself carried by a frame turning round a vertical central
pivot on the lower carriage of the waggon.
"
My invention has for its object a novel method of forming and arranging a catch
by which the body of the waggon is prevented from either swivelling upon its
vertical axis or being "tipped upon its transverse axis, until the catch is released,
the action of so releasing the catch at the same time opening a fastening which
holds a door suspended from an axis on its upper edge, and which closes the front
end of the body of the waggon until the fastening is released.
Underneath the body of the waggon I arrange a central longitudinal bolt or bar
capable of turning in bearings in the frame of the body, and having at its front
end a tongue or catch projecting at right angles, so that when the suspended door
at the front of the waggon is closed and the catch turned upward the door is held
closed until the bar is turned round and the catch turned down, when the door is
released and can open for the contents of the waggon to be discharged.
At the other, or back, end of the waggon the longitudinal bar is formed with an
eye through which passes freely a bar having a projecting handle at its upper end,
this bar being vertical when the catch at the other end of the longitudinal bar is
turned upward.
is
To the lower end of the back of the waggon body is fixed a bolt having a
projecting horizontal eye into which the lower end of the moveable bar just
described can drop when in a vertical position, and to the frame of the waggon
hinged a link or shackle which can be raised and turned over the horizontal
eye just described when the waggon body is resting upon the frame in its proper
position and the moveable bar is raised sufficiently.
If, therefore, the link just described is turned over the horizontal eye, and the
moveable bar is turned into a vertical position it turns with it the catch at the

page_text: other end of the horizontal bar and fastens down the suspended door, and the move-
able bar can be dropped until its lower end passes through the eye, outside the link
which has been passed over and holds down the latter, and the waggon body is
then firmly and securely held so that it can neither be swivelled nor tipped nor can
the door at its front end be opened.
By raising the moveable bar sufficiently and then turning it round into a hori-
zontal position, the link can be turned down so that the waggon body can be both
swivelled and tipped and at the same time the suspended door at its front end is
unfastened.
The invention may be applied to tip waggons of all kinds, whether swivelling
upon a centre pivot or not; and by its use pins and catches of the kind ordinarily
used are not required, such pins and catches being always liable to be broken or to
slip out.
The improved apparatus is simple, cheap, and very easily and quickly worked by
one person.
I, PERCIVAL FOWLER, of Queen Square Place, in the City of Westminster, Civil
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 and accompanying drawing, (that is to say) :-

the waggon a central longitudinal bolt or bar capable of turning in bearings in the
