do hereby declare the nature of said invention for IMPROVEMENTS IN STOPPERING
APPLIANCES AND JOINTS OR COUPLINGS FOR RECEPTACLES OR FLUID CONDUITS.
WITH CIRCULAR OPENINGS, to be as follows:-
The present invention relates to receptacles and fluid conduits with circular
openings, and consists in the combination of a hermetic joint or coupling with
automatic spring catches adapted to lock or secure the two parts after having been
joined together.
The working of the apparatus which may be clearly seen by reference to Fig 1
is in all modifications substantially the same. In the form represented by Fig 1
two elastic locking bolts b b which are constantly pressed inward by springs
engage at c¹ behind the conical projection c when the locking apparatus is pressed
on the opening of the receptacle. During this pressure, the tension of a spring of
indiarubber or other material must be overcome which forms a tight packing
between the lid and the receptacle when the bolts or spring-catches 6' 6' meet.
o is the buffer spring, one end of which acts on the conical tube c fixed to the
tube while the other end acts on the sleeve provided with the cone c. By pressing.
the lid on the opening of the receptacle the bolts 6' bare pressed back, the springs
of the same are stretched, the cone c is tightly pressed against the seat e¹ of the
receptacle A until the bolts 6' 6 finally engage at c' behind the cone c.
A tight
joint is thereby obtained which can be easily loosened by pressing on the knobs K.
see Fig 5, or by withdrawing, the knobs see Fig 1, whereby the bolts 66 are
withdrawn.
The novelty of this invention is the combination of this locking mechanism with
an ordinary hermetic joint or packing, such as a buffer or spring joint for the
purpose of obtaining a tight locking or closing of receptacles with circular openings
adapted to be easily opened.
The annexed drawing represents various modifications and shapes of this locking-
mechanism.
The locking cone may either be attached to the vessel or to the lid; either inside
or outside.

from the vessel; 61 are the locking bolts attached to the top of the vessel A.
The spring o (Figs 1 and 2) which serves to press the face e against the seat e¹ of
the vessel may be replaced by an elastic coupling m. This arrangement has the
advantage that the tube / need not be made fast to the valve c, whereby the latter
may be adjusted according to the depth of the vessel. The springs which cause
the locking-bolts to engage may be arranged sideways or at any suitable part of
the vessel as shown by Figs 4 and 5, or the springs may themselves serve as locking.

is made fast to the oil receptacle A, while the burner is made fast to the lid as in
Fig 11.
Fig 14 represents the application to a round burner of a petroleum lamp.
Figs 15 and 16 represent the locking mechanism applied to lamps, in which the
indiarubber ring or coupling is omitted and replaced by the helical spring o. In
the modification represented by Fig 15 the packing is effected by arranging the
metal cone c on the outside while in the modification represented by Fig 16 the
metal conc c is arranged inside. Fig 17 represents the mechanism applied to a
gas burner and Fig 18 represents the same applied to a tube connection; f is the
fixed gas pipe with the cone c c.
Fig 19 to 21 represent a combination of a pair of elastic bolts b¹ b' with a
packing-ring d which extends when pressure is brought to bear on the same.
By pressing the lid c on the packing d the latter is bent outward and forms the
packing on the neck of the vessel A; the bolts 61 b₁ engage with the lid c and thus
form the stay between the lid and the vessel. By pressing the bolts together the
lid is disengaged. 8 s¹ is an elastic ring for the bolts b¹ b¹.
In the modification represented by Figs 22 to 24 the packing ring respectively
the packing buffer is replaced by a cylindrical or conical guide. The weight of the
upper part of the locking mechanism with the packed guide has the same effect as
the combination of the elastic bolts with the packing ring see Fig 22, x. Figs 23
and 2+ represent a modification of this locking mechanism forming a tight packing
without the indiarubber ring the part a, b of the face a, b, g being horizontal while
part b, g is slightly inclined.

do hereby declare the nature of my invention for IMPROVEMENTS IN STOPPERING
APPLIANCES AND JOINTS OR COUPLINGS FOR RECEPTACLES OR FLUID CONDUITS
WITH CIRCULAR OPENINGS, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
The working of the apparatus, which may be clearly seen by reference to Fig. 11
of the drawings filed with the provisional specification is in all modifications sub-
stantially the same. In the form represented by Fig. 1. two elastic locking bolts b¹ b₁
which are constantly pressed inward by springs engage at c¹ behind the conical
projection c, when the locking apparatus is pressed on the opening of the receptacle.
During this pressure the tension of a spring of indiarubber or other material must
be overcome which forms a tight packing between the lid and the receptacle, when
the bolts b¹ b¹ meet.
o is the buffer spring, one end of which acts on the conical tube e fixed to the
tube while the other end acts on the sleeve provided with the cone c.
By pressing the lid on the opening of the receptacle, the bolts 61 6¹ are pressed
back, the springs of the same are stretched, the cone c is tightly pressed against
the seat e' of the receptacle A until the bolts b' b finally engage at c' behind the
cone c. A tight joint is thereby obtained, which can be easily loosened by pressing
on the knobs K, see Fig. 5, or by withdrawing the knobs, see Fig. 1, whereby the
bolts b¹ bare withdrawn.
The novelty of this invention is the combination of this locking mechanism with
a packing mechanism such as a buffer, spring etc for the purpose of obtaining a
tight locking or closing of receptacles with circular openings, adapted to be easily
opened.
The drawing filed with the provisional specification represents various modifi-
cations and shapes of this locking mechanisın.
The locking cone may either be attached to the vessel or to the lid; either inside
or outside.
.
Figs 1 to 3 represent the arrangement of a lid provided with the conical
packing c, and the elastic movable knobs K, which permit the removal of the lid
from the vessel; bare the locking bolts, attached to the top of the vessel A. The
spring. (Figs 1. and 2) which serves to press the face e against the seat e¹ of
the vessel may be replaced by an elastic coupling m. This arrangement has
the advantage, that the tube l need not be made fast to the valve c, whereby the
latter may be adjusted according to the depth of the vessel. The springs which,
cause the locking-bolts to engage may be arranged sideways or to any suitable part
of the vessel, as shown by Figs 4. and 5. The springs may themselves serve as
locking bolts, as in Fig. 6, where the oval spring 8 8¹ carries at its hinges the
knobs K, so that by pressing on the latter, the locking cone is disengaged.
Fig. 7 represents a modification of the spring, serving as a locking bolt. On
the left side the neck of the metal vessel A is recessed, so that the tongue forms
the elastic bolt; on the right side there is a special locking spring.
Fig. 7a represents a somewhat modified construction made sufficiently clear by
the drawing.
Fig. 8 represents an application of the oval spring 8 8', shown in Figs 6 and 7,
the locking bolts 6' being elastic, and attached to spring 8 st.

page_text: Fig. 9. represents a modification in which the lid carries two rivetted springs z z¹,
while the elastic coupling m, represented in Fig. 3, is in this case applied as an
indiarubber ring.
Fig. 10, represents the springs 2' mounted on the lid and applied externally.
The other figures represent various applications of this locking mechanism.
Figs. 11 to 16 represent the application of the locking mechanism to an ordinary
split burner for petroleum lamps.
The cone c which serves for fastening the lid (by pressing the latter on the lamp)
is made fast to the oil-receptacle A, while the burner is made fast to the lid, as in
Fig. 11.
Fig. 14 represents the application to a round burner of a petroleum lamp.
Figs 15 and 16 represent the locking mechanism applied to lamps, in which the
indiarubber ring or coupling is omitted and replaced by the helical spring o. In
the modification represented by Fig. 15 the packing is effected by arranging the
metal cone c on the outside, while in the modification represented by Fig. 16 the
metal cone c is arranged inside.
Fig. 17, represents the mechanism applied to a gas burner, and Fig. 18 represents
the same applied to a tube connection; f is the fixed gas pipe, with the cone c c¹.
Figs. 19. to 21 represent a combination of a pair of elastic bolts b b with a
packing-ring d, which extends, when pressure is brought to bear on the same.
By pressing the lid c on the packing d, the latter is bent outward and forms the
packing on the neck of the vessel A; the bolts b₁ b¹ engage with the lid c and thus
form the stay between the lid and the vessel. By pressing the bolts together, the
lid is disengaged. 88' is an elastic ring for the bolts b¹ b'.
In the modification represented by Figs 22 to 24, the packing ring, respectively
the packing buffer, is replaced by a cylindrical or conical guide; the weight of the
upper part of the locking mechanism with the packed guide has the same effect,
as the combination of the elastic bolts with the packing ring, see Fig. 22, x.
Figs 23 and 24 represent a modification of this locking mechanism forming a
tight packing without the india rubber ring, the part a, b of the face a bg being
horizontal, while part 6 g is slightly inclined.
