Louis Blanck, of New York city, has patented an improved Safety Brake or
attachment for locomotives and railroad cars, by which the entire train,
either by a collision with another train or by contact with any
obstruction, is first raised from the rails, and then moved in backward
direction for the distance of a few feet, so that all danger of accident
is avoided, and no other sensation than that of a slight rocking motion
exerted. The attachment is constructed so as to admit of being worked by
the engineer from the cab or the locomotive, or, if desired, from any
car of the train.
An improved Evaporating Pan had been patented by Andrew D. Martin, of
Abbeville, La. This invention consists in a tapering sheet metal tank
having transverse partitions and longitudinal tapering flues that extend
through all of the partitions and terminate at the ends of the tank.
Lloyd Arnold, of Galveston, Texas, has patented an improved Bale Tie,
which is formed of a block of iron, with a space or opening running
longitudinally through its breadth from one end nearly to the other, and
having the alternate edges of the two plates thus formed notched, the
notch of the lower plate being square and of a width equal to or a
little greater than the bale band, and the notch of the upper plate
being narrower at its bottom than the bale band, and with its sides
inclined and beveled to an edge, to adapt it to receive and hold the
bale band.
An improved Tie for Letter Packages has been patented by John Mersellis,
of Knowersville, N. Y. The object of this invention is to provide a tie
by means of which letter packages may be quickly and securely fastened
or tied. It consists in a plate apertured to receive one end of the
string and also to receive the hook upon which the tie is hung when not
in use, and having a button and clasp spring for engaging the string in
the process of tying.
Fred P. Hammond, of Aurora, Ill., has patented an improved Inking Pad,
which consists in a novel arrangement of layers of cloth or felt,
chamois skin, oiled silk, and printing roller composition, which enables
a clean impression of the stamp to be made. The pad retains the desired
rounded surface and proper degree of softness, and is easily manipulated
when necessary to replenish the supply of ink.
William J. Clark and Thomas W. Roberts, of Coffeeville, Miss., have
patented an improved Trap for Catching Fish in streams, which will allow
the fish to be conveniently taken out without taking up the trap.
