IMPROVEMENTS IN STAITIIS AND, APPARATUS IN CONNECTION THEREWITH FOR THE MORE RAPID SHIPMENT OF COALS, MINERALS, AND OTHER LIKE MATERIALS, FROM RAILWAY WAGONS
Year: 1884

page_text: I SAMUEL BUTLER, of N° 5 Chancery Lane, London, Engineer do hereby declare
the nature of the said Invention for IMPROVEMENTS IN STAITIIS AND, APPARATUS
IN CONNECTION THEREWITH FOR THE MORE RAPID SHIPMENT OF COALS, MINERALS,
AND OTHER LIKE MATERIALS, FROM RAILWAY WAGONS," and in what manner the
same is to bo performed, to be particularly described and ascertained in and by
the following statement :—
This Invention has reference to a prior Invention of "Improvements in Staiths
and Apparatus in Connection therewith for the more Rapid Shipment of Coal,
Minerals, and other like Materials, from Railway Wagons," of which a Complete
Specification was filed by me in the Great Seal Patent Office on the 21 day of
July 1884, N° 10,414, and the prosent improvements relate to the arrangement of
certain parts of the apparatus described in the said Specification and particularly
in respect to Figures 3 and 4 of the Drawings thereof.
The objects of my Invention are:-
First, to avoid loss of time in moving a ship whilst loading.
Secondly, to economise quay space by keeping the ship stationary.
Thirdly, to load into two or more hatchways at the same time.
Fourthly, to avoid loss of time in trimming the cargo by putting the coal into
one part of the ship whilst the trimming is done in another.
Fifthly, to avoid breakages now occasioned by allowing the material to drop from
the mouth of the shoot into the ship.
Sixthly, to do away with complicated and expensive lifts in shipping from high
level.
My Invention has also reference to apparatus for opening and closing the box or
receptacle in which the material is lowered and also for opening and closing the
mouth of the shoot, and in order that it may be more fully understood I herein
give reference to the accompanying Sheet of Drawings in which, Figure 1 is side
elevation partly in section of my staith and appliances.
Figure 2 a front elevation thereof and Figures 3 and 4 enlarged views of
lowering box or vessel.

page_text: A is the framework of the staith, the upper portion of which may be movable on
rails a, and the carriage B is likewise movable on rails b. C is the tilting table
operated by hydraulic ram E as described in my previous Specification. F is the
shoot, the mouth of which may be closed during the descent of the box G by a
door Has hereinafter described.
Upon two shafts K. L. are keyed a series of pullies 1. 2. 3. 4. 5. and 6. and also
two brake wheels 7 and 8. Two arms or gibs M are connected by shaft N which
carries two pairs of guido pullies corresponding with the pullies 2. 3. 4 and 5. on
the shafts K. L. From the pulley 1 a chain passes to the back of the staith having
at its end a counterbalance weight c and from the pulley 6 a similar chain also
passes having a smaller weight at the end thereof. The box G is suspended by
two sets of chains, one set a being attached to the sides of the box, and to a cross-
bar e, the cross-bar being in its turn suspended by chains f which pass around
pullies 2 and 5. The second set of chains g are attached to the doors or hinged
sides of the box at h and after meeting on each side so as to form two single chains,
pass around the pullies 3 and 4. The weighted lever O shewn only in Figure 1
when allowed to fall during the descent of the box G, acts upon the link i and
lever and raises the door H thus closing the mouth of the shoot which is opened
again when the box rises by means of the cross bar e which raises the weighted
levers on each side of the shoot. The box G operatos as follows:-When in position
for filling as shewn in the Drawing the brake wheel 7 is held the other one being
loose thus putting the weight of the box on the door chains g, the heavier the box
becomes the greater will be the tension on the doors. The box being full, the
brake wheel 7 is released and it then descends until it arrives at the situation for
effecting the discharge, when the brake wheel, 8. is, checked, thereby stopping the
descent of the box and removing the weight from the chains g to the chains fand
the former set being no longer in a state of tension, are unable to resist the
pressure of the material within the box which forces open the doors and escapes
into the ship. The brake wheel 8 is now removed and the empty box overcome
by the weight C is raised to the filling position by the winding of the chains f
onto the pullies 2 and 5, the slack chains 7 being likewise wound upon the
pullies 3 and 4 by the counterbalance weight attached to the chain around
pulley 6.
-
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 :-
1. The general arrangement of a staith or stage constructed as and for the
purposes, substantially as herein shewn and described.
2. The use of a travelling carriage for carrying trucks to and from the tipping
appliances, substantially as herein shewn and described.
3: The general arrangement of chains and pullies for lowering and raising the
box G as herein shewn and described..
4. The method of and apparatus for opening and closing the mouth of the shoot,
substantially as herein shewn and described.
