CAST METAL CASES FOR SPRING BALANCES.--John Chattillon, New York
city.--This invention relates to a new manner of arranging the cast
metal cases for spring balances, so that they can be made less expensive
and simpler than they are now made, and consists in fitting the iron, to
which the upper end of the spring is secured, directly through the upper
head of the case, instead of using an additional head in the case for
that purpose.
TWEERS.--John B. Himberg, Frederick City, Md.--This invention relates to
a new tweers, which is so arranged that the center part or ring can be
easily taken out, whenever desired, but not accidentally, by a hook or
stirrer, and that it can be easily cleaned and taken apart whenever
desired, and that it may conduct a strong blast of air to the fire.
PUNCH.--C. D. Flesche, New York city.--This invention consists in
arranging a punch in such a manner that it consists of two parts, which
are firmly connected together for cutting the metal, while for bending
the same, an inner sliding punch will be moved out of the stationary
cutting punch, thus making both operations by one instrument, and
avoiding the removal of the article from the cutting to the bonding
punch, which was heretofore necessary.
