PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Shot and in Apparatus therefor.
I, GERHARD LAMPEN, of 5 Grasmere Terrace, Gateshead-on-Tyne, in the County
of Durham, Shot Manufacturer, do hereby declare the nature of this invention to be
as follows:-
According to the usual practice prevailing in the manufacture of shot, the molten
lead is carried in hand ladles from the melting pot to the frame through which the
metal is passed before falling down the shaft into the water-tank.
According to my improved method of manufacture, I convey the molten lead by
means of a ladle of improved construction and with the aid of suitably formed and
disposed spouts or conduits from the melting pot to the frame.
My improved ladle for the purpose above referred to is constructed in such a
manner as to enable the spouts or conduits to be supplied with a continuous stream of
the molten lead; and is furnished with appliances whereby the supply may be
regulated.
The spouts or conduits I employ are formed of iron or other suitable material
and are arranged with sufficient fall to cause the molten metal to flow direct
to the frame.
In some instances, I dispense with the use of the ladle and run the molten lead direct
from the melting pot to the spout or conduit before referred to, the melting pot being
mounted on trunnions or otherwise for the purpose of facilitating libation of its
contents.

page_text: Improvements in the Manufacture of Shot and in Apparatus therefor.
I, GERHARD LAMPEN, of 5 Grasmere Terrace, Gateshead-on-Tyne, in the County
of Durham, Shot Manufacturer, 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 :-
According to the usual practice prevailing in the manufacture of shot, the molten
lead is carried in hand-ladles from the melting pot to the frame through which the
metal is passed before falling down the shaft or from a tower into the water-tank..
According to my improved method of manufacture, I convey the molten lead from
the melting pot to the frame by means of a ladle of improved construction, or by
means of suitably formed and disposed spouts or conduits.
And in order that my invention may be fully understood, I will proceed to describe
the same with the aid of the accompanying drawings; whereof Figures 1 and 2
represent, in side elevation and plan respectively, a ladle constructed and mounted
according to my improved method. The ladle consists of a bowl a mounted on
trunnions in the carrier b. One of the trunnions is extended into a shank c provided
with handles ce¹ arranged in a suitable manner for enabling the ladle to be tipped.
The ladle may be formed with a pouring lip on either or both sides. The carrier bis
suspended midway by means of a chain or other suitable connection d from the short
arm of a lever e. The outer extremity of the shank is suspended in a sling f¹ con-
nected by means of the chain f with the long arm of the lever e. The lever e is
furnished with a counterbalance weight g, arranged to slide upon the said lever and to
be secured in its requisite position by means of a set-screw or locking pin. The whole
apparatus is suspended by means of a chain or other suitable connection 4, attached to
the pivot of the lever e, and leading to a crane or derrick if desired. The method of
manipulating the apparatus will be obvious without further explanation.
In Figures 3 and 4 is represented, in side elevation and plan respectively, an
alternative construction of trunnion-mounted tipping ladle, more especially adapted
for working larger charges of metal and designed for use in conjunction with spouts
or conduits (hereinafter more fully described) for conveying the molten metal in
continuous streams to the frames. With this construction of apparatus, the container
may be heated and utilised as a melting pot. The container a is mounted on trunnions
in the frame b. One of the trunnions is furnished with a worm-wheel c which gears
with a worm c¹, the latter being actuated by the hand-wheel d. The container is
provided with one, two or more pouring lips a¹ for delivering the molten lead to the
conduits, or to a basin communicating with the said conduits. The molten metal
may, however, be drawn from the container or melting pot a into ladles of the kind
hereinbefore described with reference to Figures 1 and 2, and thus conveyed to the
frames. In either case, the delivery of the molten metal from the container or melting
pot a is regulated with facility and safety by means of the hand-wheel d.
In Figures 5 and 6 is represented, in side elevation and plan respectively, my
improved arrangement of melting pot in conjunction with spouts or conduits for
conveying the molten metal to the frames. k is the melting pot with branch outlet k³,

page_text: furnished with an appliance for regulating the delivery or for shutting off same. This
appliance is shown in face view in Figure 7, and comprises a hand lever 1, pivotted
at and working within a guard-strap 12. The lever 1, when in the position
indicated in Figure 7, is immediately in front of and closes the delivery orifice of
the melting pot. It will, however, be obvious that other means may be employed for
controlling the delivery. The issuing metal is received in a basin m, whence it is
conveyed, by means of the spouts or conduits m², to the frames; the said conduits
being arranged at a suitable inclination. One, two or more spouts, such as m¹, may
be fed from a common receiving basin, such as m. Or the receiving basin may be
dispensed with, and each spout or conduit supplied from the melting pot through an
independent delivery orifice. In the present illustration, the two conduits m³ with
their common receiving basin m are intended to be bodily removable. When placed
in position, the apparatus is carried at one end by the support m², whilst the outer
extremities of the conduits may rest on the frames (not shewn in the drawing). The
length of the conduits is dependent on the relative distance of the frames. As before
stated, such or similar conducting apparutus may be used in conjunction with a
tipping ladle or melting pot of the kind hereinbefore described with reference to
Figures 3 and 4.
Having thus particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
First In the manufacture of shot, the improved method of and means for
conveying the molten metal from the melting pot or other container to the frame,
substantially as herein described; such means consisting of inclined spouts or conduits,
constructed singly or in multiple, and whether communicating with a common supply
basin or otherwise.
Secondly-As alternative means for conveying the molten metal from the melting
pot to the frame in the manufacture of shot, the improved construction of balance
ladle arranged and operating substantially as described with reference to Figures 1
and 2 of the accompanying drawings.
Thirdly The improved construction of tipping ladle arranged and operating
substantially as described with reference to Figures 3 and 4 and adapted for use as a
melting pot.
Fourthly For use in the manufacture of shot, the combination of a tipping ladle
or melting pot, having one or more pouring lips, with one or more conduits serving
to convey the molten metal to the several frames.
Fifthly For use in the manufacture of shot, the combination of a melting pot,
having one or more regulated outlets, with one or more conduits serving to convey the
molten metal to the several frames.
