COMPLETE SPECIFICATION.
Improvements in and connected with Receptacles with Self-closing
Covers.
We, EMIL RICHARD BERUDE and MORITZ BERNHARD EMIL SOBADKY, both of
Blasewitz, near Dresden, Kingdom of Saxony, Germany, do hereby declare the
nature of our invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention has reference to Improvements in and connected with re-
ceptacles," such as beer-glasses, milk-cans, jugs, paint pots and the like and
relates more especially to means whereby the cover of such receptacles will open
by pressure being exerted by a finger, preferably the thumb, upon a fingerplate
and will automatically close, when the finger is taken off the fingerplate. This
opening and closing is accomplished by a spring and lever mechanism which
we will now proceed to fully describe with reference to the accompanying sheet
of drawings, in which Fig. 1 shows a top view of the cover actuating mechanism,
in connection with a circular cover. Fig. 2 is a sectional elevation of the
mechanism, attached to a beer-glass only partially shown, the cover being in closed
position.
Fig. 3 is the same sectional elevation, the cover being in opened position.
Like characters of reference indicate like parts in the three figures.
The cover is provided with a rubber or other suitable washer ring a, adapted
to rest upon the upper edge of the receptacle when the cover is closed thereby
preventing the contents of the receptacle from running out in case the receptacle
should have been inadvertently knocked or tipped over. Two disc-shaped hinge
parts running out into the common projection are fastened with this pro-
jection to the cover by means of rivets or by being soldered or brazed thereto.
This hinge part e is pivotted at d between two upstanding ears or flaps f extending
upwardly from the receptacle whereto they are fastened by the hookshaped part fi
hooked over the upper edge of the receptacle and by the clamp part 2 clamped
around the handle of the receptacle, as is clearly shown in Fig. 2. Thus by
unclamping the part f² and by unhooking the part fi the cover with the mechanism
hereinafter described can easily be removed should the receptacle be broken.
Between the said upstanding ears f the triangularly shaped levers i are pivotted
at g and are connected by the finger plate h. A link pivotally secured to the
hinge parts e at m is provided at its lower end with a slot and the levers i are
connected by a pin o, taking into the said slot in the link 7.
A helical spring & also connects the hinge parts c and the levers i, this spring
to be arranged between the pivot d and the pivot g, while the link 7 is arranged
on the other side of the pivot d.
If now pressure is brought to bear upon the finger plate the levers i are swung
downwardly about their pivot g, thereby drawing the link with it and causing
the hinge parts & and the cover to swing about the pivot d into the position shown
in Fig. 3, the helical spring being drawn out. If the fingerplate is released the
cover will be caused to swing shut by the helical spring contracting again. In
order to prevent the cover from opening inadvertently for instance by the re-

page_text: ceptacle being upset, a projection or nose p is provided upon the upper edge of
one of the levers i and a recess q is provided in the lower edge of the respective
hinge part c. Ordinarily the nose will take into the recess q, the spring
holding the parts c and i together and the pin o will rest in the upper part of
the slot n in the link 7, as is shown in Fig. 2. It is now impossible for the cover
to open by being lifted directly or by the contents of the receptacle pressing
against it, as the parts c and i are fixed in their relative position by the said nose p
engaging the recess 7. If now the fingerplate is pressed downwards, it will
descend without at first taking the link along, the pin o gliding the length of
the slot n, when the nose will be lowered out of the recess g, but on further
down-motion of the fingerplate the cover will be raised as above described. In
letting the cover down again, the nose will take into the recess 7 and thus secure
the cover again against inadvertently being opened.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In receptacles with selfclosing covers the combination of the two upstanding
ears or flaps f, the two parts f¹, f of which are secured to the receptacle, the
disc-shaped hinge parts c secured to the cover b and being pivotted between the
said flaps f, a link pivotally secured to the said hinge parts c and to the levers i,
said levers i to be pivotally secured to the said flaps f, a finger plate / connecting
the said levers i and a helical spring secured with one end to the said hinge parts c
and with the other end to the said levers i, all for the purpose set forth.
2. In receptacles with selfclosing covers the combination of the two upstanding
ears or flaps f, the two parts f', f of which are secured to the receptacle, the
disc-shaped hinge parts secured to the cover and being pivotted between the
said flaps f, a link pivotally secured to the said hinge parts c and to the levers i,
said levers i to be pivotally secured to the said flaps f, a finger plate h connecting
the said levers i and a helical spring secured with one end to the said hinge parts c
and with the other end to the said levers i, a projection or nose upon the upper
edge of one of the said levers i, taking into a recess g provided in the lower edge
of the respective hinge part c, a pin o connecting the said two levers i and a
slot provided in the lower end of the said link 7 the parts being constructed,
arranged and working substantially as and for the purpose set forth.
