Improvements in Waggon-tipping Mechanism.
I, HENRY Harington Leigh, Assoc. M. Inst. C.E., Fel. Inst. P.A.,
practising as Phillips & Leigh at No. 22, Southampton Buildings, Chancery
Lane, in the County of Middlesex, Engineer and Patent Agent, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in waggon-tipping mechanism.
In carrying it into effect, two or more parallel shafts are supported in suitable
bearings. Each shaft carries two or more drums, those on one shaft being aligned
respectively with those on the other or others. In the vertical plane above each
line of drums stands a ring. These rings are braced together by a pair of rails
adapted to receive the waggon to be tipped and also by suitable bars adapted to
hold the waggon during the motion of tipping, which is preferably a continuous
circular one.
One of the shafts above mentioned is kept constantly rotating and
so long as the rings are in contact with the drums on the said shaft so long will the
tipping motion be maintained. It is interrupted by the following mechanism which
may be applied to each ring.
A transverse shaft carries a releasing and a locking lever. The nose of the latter
engages in a notch in the ring for the purpose of locking the tip. A counterpoise
is also linked to the said locking lever to keep it in touch with the periphery of the
ring during the tip, and to pull it into the notch at the proper moment. A wedge is
connected by a link to the lever mechanism above mentioned. A suitable slope is
provided for the wedge to travel on. By the time the tip is locked the wedge has
been pulled down under it and lifted it off the first motion drums. I do not confine
myself to the wedge device for lifting the tip off the drums, but may use a special
lever for the purpose, said special lever being connected to the lever mechanism
above mentioned so as to be brought to bear upon the tip at the proper moment.
Dated this 17th day of July 1891.

Improvements in Waggon-tipping Mechanism.
1, HENRY HARINGTON LEIGH, Assoc. M. Inst. C.E., Fel. Inst. P.A.,
practising as Phillips & Leigh, at No. 22, Southampton Buildings, Chancery Lane,
in the County of Middlesex, Engineer and 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 :-
This invention relates to improvements in waggon-tipping mechanism.
In carrying it into effect, two or more parallel shafts are supported in suitable
bearings. Each shaft carries two or more drums, those on one shaft being aligned
respectively with those on the other or others. In the vertical plane above each
line of drums stands a ring. These rings are braced together by a pair of rails
adapted to receive the waggon to be tipped, and also by suitable bars adapted to
bold the waggon during the motion of tipping, which is preferably a continuous
circular one.
One of the shafts above mentioned is kept constantly rotating, and so
long as the rings are in contact with the drums on the said shaft, so long will the

page_text: respective rings 9, y' and keep the latter clear of their respective drums c, c. The
teeth are also in their respective slots g². When the waggon is to be tipped,
the lever is pulled away from it thereby disengaging the teeth l from the slots y³,
and pulling the wedges up the inclines m far enough to let the tip down upon the
revolving drums. The lever is then let go, and the counterpoise holds the
teeth /' against the surfaces of the now revolving rings. By the time the waggon is
upside down, its contents have been tipped, itself being held up the braces h
and the plates . The tip is kept revolving until the slots are opposite the
teeth which are pulled into their respective slots and the wedges n pushed
down between their respective rings and inclines by the counterpoise p, the
extensions bearing upon the rings and supporting the teeth.
The modification illustrated in Fig. 6 consists in arranging for the tip to
be revolved in the opposite direction to the one indicated by the arrows in Figs. 1
and 4. Consequently the detents are below the shaft, the wedges and inclines
tapered the other way, and the arm p' and counterpoise outside the lever which is
therefore pushed to unlock the tip.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The combination of drums, rings braced together so as to receive a waggon and
resting by gravity upon the said drums, with a wedge-and-lever device by which
the rings are alternately lifted off the first motion drums by the insertion of the
wedge device and dropped thereon by its withdrawal through the lever, as set
forth.
