I do hereby declare the nature of this invention to be as follows:-
There is a metal boiler "for melting the lead" with cutting door "to regulate the
flow of molten lead" situated close to a deep well.
There is a traveling ladle or boat, which has attached to it a weight, to bring back
the ladle or boat, after it has emptied itself into a apparatus, which is circular in
shape, and having holes of regulated sizes, for dividing the molten lead from the
boiler into globules, which are precipatated into the well. This apparatus is slung on
a rail overhead, and can be removed for the purpose of cleaning the same.
There are
two of those apparatus, slung on the overhead rail, and immidiatly one goes off for
oleaning the other has already passed round the tube on to the well again, so as not to
stop the men, and create a continuous casting.
The apparatus now used, are square this square is formed, into four parts, and
therefore causing four angles or corners in each part, which now causes the apparatus
to be imperfectly cleaned, and a great deal of delay arises.
In the apparatus I porpose
to obviate this, by making it circular.
After the globules are precipatated into the bottom of the well, they are immidiatly
taken up by a spiral worm or chaincup (elevators) and passed through a heated
cylinder or tube about twenty feet high, and dryed in their passage.
They empty themselves into an hopper on the top of the tube, from here; they are run
by a spout into a double cleaning cylinder, which is likewise heated. The first refuse is
more taken out by a double cylinder than by a single one, as now used" and is
carried out on the front of the cylinder into a spout connected with the boiler. The
perfect shot drops through the holes in it, into a polishing machine immidiatly under
the cylinder, having two polishers so placed, that one can be filling while the other is
polishing.

page_text: After the shot is polished, it runs direct onto a cleaning table, being over six by
three feet in size. This table is made to vibrate, by being suspended on two iron
arms, which are resting on two toothed wheels and regulator, and the surface of this
table, is divided into three sections, having two slits, to more accurately clean the shot
before it runs into a separator, and to take out the second and last refuse by a spout
under the table into a reserve cask, and renders the use of several tables unnecessary.
My invention i.e. the above described machinery, and the arrangement thereoff, is a
great improvement over the machinery now in use, as so much fewer hands are
needed.

boat, ladle, or spout.
2nd. The arrangement of the elevators to bring the shot up continuously as it is
being cast.
3rd. The drying of the shot in an iron tube, and cylinder, during its passage
through.
4th. That by having a double cylinder instead of a single one, as now used, the first
refuse is more thoroughly taken out.
5th. Having the polishers directly under the cylinder, the work goes on automatically,
thus saving many hands.
6th. That by having two polishers, one can be filling while the other is polishing.
7th. That the surface of the cleaning table being over six by three feet in size, and
in three sections, the first quite plain, the second is roughed over, the third corrugated,
having the three parts as a whole suspended and made vibrate, cleans the shot quite
perfectly and renders the use of several tables unnecessary.
