IMPROVED RECEPTACLES OR VESSELS WITH AUTOMATICALLY MOVING COVERS, LIDS, OR TRAPS
Year: 1881

page_text: LETTERS PATENT to Friedrich Carl Glaser, of Berlin, in the Kingdom of
Prussia and Empire of Germany, Engineer and Patent Solicitor, for an
Invention of "IMPROVED RECEPTACLES OR VESSELS WITH AUTOMATICALLY
MOVING COVERS, LIDS, OR TRAPS." A communication from Hermann
Schomburg, of Alt-Moubit, near Berlin, Germany.
PROVISIONAL SPECIFICATION left by the said Friedrich Carl Glaser at
the Office of the Commissioners of Patents on the 4th January 1881.
FRIEDRICH CARL GLASER, of Berlin, in the Kingdom of Prussia and Empire
of Germany, Engineer and Patent Solicitor. "IMPROVED RECEPTACLES OR
VESSELS WITH AUTOMATICALLY MOVING COVERS, LIDS, OR TRAPS." A communi-
cation from Hermann Schomburg, of Alt-Moubit, near Berlin, Germany.
Many household utensils now in use for the reception of various kinds of waste
paper and other articles or liquids, such, for example, as cinder-boxes, spittoons, dirt
scuttles, inkstands, etc., have the defect that the matters deposited therein remain
exposed, their stench may infect the place, they may offend the sight, or they may
dry up too rapidly, as ink-for example.
The object of the construction hereinafter described is to obviate these defects, or
to suitably modify the articles in question.
This arrangement instantaneously hides all these articles from the sight, so that
they remain completely hidden until they are discharged; this construction may
also be used as a dipper for aquariums or other liquids, for playthings, and for
various other objects.
The object above set forth is attained by means of automatically turning covers
fitted to these receptacles, which covers lower under the weight of the article
or matter laid thereupon, and cause such articles or matters to pass into the
receptacles.
The overweight or counterweight which acts upon the other end of the covers
causes them to close automatically

page_text: I would here observe that the covers might also be fitted with springs and
counter springs of a spiral form or spiral springs.
The accompanying Sheet of Drawing shows two different constructions of these
covers, that on the left being intended for solid bodies, whereas that on the right is
to serve for liquids, etc.
In both arrangements I use a cover a, b, turning upon an axle c, and provided
with a piece d.
The cover of the construction drawn on the left, intended for solid bodies, is
massive, whereas the other, serving for liquids, takes at its lower part the shape of a
shovel.
Thus, when any kind of article is placed upon the part a of the cover, it causes
this latter to turn under its weight following the arc x.
The article then passes
into the receptacle, and the cover resumes its primitive position, actuated by the
overweight of the part a.
The piece d fitted to the cover prevents it turning too far, while the stop e of
the receptacle does not permit the part 6 to advance beyond the proper point.
The shape of the covers and of the receptacle may be greatly varied, and similar
or different materials may be used in their manufacture. They may be of wood,
sheet iron, porcelain, earthenware, glass, paper, papier mâché, or of any suitable
kind of metal or material.

Having now described and ascertained the nature of the Invention communicated
to me as aforesaid, and in what manner the same is or may be performed,

page_text: I claim as secured to me by the herein before in part recited Letters Patent,-
The use of receptacles or vessels having an automatically moving lid or cover
arranged to operate substantially as and for the purposes set forth.
In witness whereof, I, the said Friedrich Carl Glaser, have hereunto set my
hand and seal, this Sixteenth day of June, in the year of our Lord One
thousand eight hundred and eighty one.
