LOUIS AUGUST SENGELE, OF VICTORIA, TEXAS, ASSIGNOR OF ONE-THIRD TO LACY T. STEELE,
OF VICTORIA, TEXAS.
POT-FEEDER FOR TYPE-CASTING MACHINES.
932,817. Specification of Letters Patent. Patented Aug. 31, 1909.
Application filed October 14, 1903. Serial No. 457,643.To all whom. it may concern:
Be it known that I, Louis Aueus r SEN-
CELE, a. citizen of the United States, and a
resident of Victoria, in the county of Vic-
5 toria and State of Texas, have invented a
new and Improved Pot-Feeder for Type-
Casting Machines, of which the following is
a full, clear, and exact description.
My invention relates to type-setting and
.10 type - casting machines, and more particu-
larly to such machines as are employed to
cast slugs provided with impression charac-
ters, each slug representing the line, or its
equivalent, to be printed.
15 The main purposes of my invention are
as follows: 1. To produce for a casting ma-
chine, in which there is a metal pot contain-
ing the type metal to be cast up into slugs, a*
device provided with means for dropping
20 into the metal pot old and useless slugs, one
at a time, as the molten metal in the metal
pot is used up in making new slugs. 2. To
render the pot feeder adjustable for slugs
of different lengths. 3. To prevent break-
25 age of any movable part, due to difficulty in
ejecting a slug. In this connection it may
not be amiss to state one or two facts con-
cerning the operation of casting machines
of the general type above mentioned.
30 To obtain the best results it is absolutely
requisite that the metal in the metal-pot
should be kept at an even temperature,
neither too hot nor too cool. It is also es-
sential that the molten metal in the pot be
35 maintained at a certain height. If the tem-
perature of the metal is too high, it will
cause hollow slugs, and will also cause the
slugs to adhere to the mold. Too hot metal
will also soon break down the matrices. If,
40 on the other hand, the temperature is too
low, the plunger cannot force the metal into
the mold properly, causing a bad and use-
less slug. If the metal gets low in the pot
it will also cause ill results. Ordinarily,
45 the operator feeds the metal in the pot by
hand, which necessitates his leaving the key-
board, causing loss of time and inconven-
ience during the day. If too much metal is
added to what is in the metal-pot, such fresh
5o metal being cool will lower the temperature
of the molten metal. The regularity with
which the gain and loss is equalized by this
contrivance, both as to quantity and time,
proves its capability of maintaining, not
55 only a regular supply of metal but a uni-formity of temperature of the molten metal.
Operators sometimes forget to put metal in
the pot at the required time, which pro-
duces the ill effects of low metal. By my
pot-feeder all these disadvantages are over- 60
come, enabling the operator to remain at
the keyboard, thereby greatly increasing the
output of the machine. My invention seeks,
therefore, upon each occasion when a sup-
ply of metal is forced out of the metal pot 65
for the purpose of casting a slug, to add to
the metal inside of the metal pot a quantity
of cold metal, equal to that ejected for .the
purpose of casting a new slug. As a con-
venient means for doing this I simply cause 70
the old slugs, which have already been used,
to be fed one at a time into the metal pot,
substantially the same movement of mech-
anism used for forcing out a charge of metal
sufficient to fill the slug mold, sufficing also 75
to drop into the metal pot an old slug or an
equivalent quantity of cold metal. By this
arrangement I replenish the metal contained
in the metal pot as fast as it is used, there-
by maintaining approximately constant the 80
quantity contained in the metal pot, and also
maintaining the temperature of the metal
pot and its contents as nearly as practicable
uniform.

purpose of enabling the movements of this
