PROVISIONAL SPECIFICATION.
Improvements in and connected with Stoppers for Bottles and
other Receivers.
I, JEAN NÉPOMUCENE HOCHGESAND, of 200, Quai Jemmapes, Paris, in the
Republic of France, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
The invention relates to an improved stopper characterised by a spring arrange-
ment which forms an automatic safety stop.
This arrangement of stopper is applicable to the covers of lubricators, to the
necks of bottles and other receivers and the like.
My invention will be well understood by the following description, reference
being had to the accompanying illustrative drawing in which:-
Fig. 1 represents my arrangement of stopper in section, applied for example to
the cover of a lubricator provided with a socket.
Fig. 2 represents a similar stopper applied to the neck of a receiver.
Fig. 3 represents a side elevation of the same stopper.
Fig. 4 represents the said stopper in the act of being placed in position or of
being removed therefrom.
In the various figures like letters of reference indicate the same parts.
As shown in the drawing, my arrangement of stopper comprises a hollow
cylindro-conoidal body a and a milled or grooved head b.
In the interior of this stopper is placed a spring with two arms e each ter-
minated by a hook or claw . The two hooks or claws of the arms engage auto-
matically with the lower edge of the socket e as shown at Fig. 1 or with an annular
groove f formed within the neck, as shown at Figures 2, 3, 4. The spring with
two arms is retained in the stopper by means of a pin g which passes into a
groove formed in an interposed washer h.
The socket or opening for the stopper being conical, it only requires the stopper
to be pushed home; the two arms of the spring will be first pushed back in con-
sequence of the conical form of the opening and spring outwards, as soon as the
hooks or claws d escape, and engage either below the socket, or within the groove,
or underneath any suitable shoulder.
It will be understood that the forms, accessories, materials and dimensions of
my improved stopper may be varied without departing from the peculiar character
of my invention, thus for example, the spring may have one, two, or a greater
number of arms.

I, JEAN NÉPOMUCÈNE HOCHGESAND, of 200, Quai Jemmapes, Paris, in the
Republic of France, Mechanical Engineer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention relates to an improved stopper characterised by a spring arrange-
ment which forms an automatic safety stop.
This arrangement of stopper is applicable to the covers of lubricators, to the
necks of bottles and other receivers, and the like.
My invention will be well understood by the following description, reference
being had to the accompanying illustrative drawings in which:-
Fig. 1 represents my arrangement of stopper in section applied, for example, to
the cover of a lubricator provided with a socket.
Fig. 2 represents a similar stopper applied to the neck of a receiver.
Fig. represents a side elevation of the same stopper.
Fig. 4 represents the said stopper in the act of being placed in position.
Fig. 5 represents in vertical section an arrangement intended to hold the arms
of the stopper retaining spring in their outward position.
Fig. 6 represents in section and in plan a plug operated by a key for the pur-
pose of moving the retaining spring.
Fig. 7 is a cross section drawn on the line 1-2 of Fig. 5.
Fig. 8 represents a modification of the stopper in which the spring is arrested
by a stop.
Fig. 9 represents a modification of the stopper in which the arms of the spring
are held apart by means of a vertically travelling nut operated by a screwed rod.
Fig. 10 represents in plan the head of the screwed rod.
Fig. 11 shows in plan the nut and parts which act on the arms of the spring.
As shown in the drawings at Figs. 1 to 4, my arrangement of stopper comprises
a hollow cylindro-conoidal body a and a milled or grooved head b. In the interior
of this stopper is placed a spring with two arms c each terminated by a hook or
claw d. The two hooks or claws of the arms engage automatically with the lower
edge of the socket e as shown at Fig. 1, or with an annular groove f formed within
the neck as shown at Figs. 2, 3, 4. The spring with two arms e is retained in the
stopper by means of a pin g which passes into a groove formed in an interposed
washer .
The socket or opening for the stopper being conical, it only requires the stopper
to be pushed home; the two arms of the spring will be first pushed back in con-
sequence of the conical form of the opening and spring outwards as soon as the
hooks or claws d escape and engage either below the socket or within the groove
or underneath any suitable shoulder.
To hold the arms of the spring a¹ apart after the stopper is placed in position,
I can employ the arrangement represented in Figs. 5 to 7. In this case the head
of the spring a¹ is lodged in a notch or recess b₁ in the underside of the plug c
which latter is rotated by means of a key. Between the two arms is located a
locking block, which is pinned at e¹ to the body of the stopper. This locking
block has two flat surfaces f¹ and two parts g' of a larger diameter, so that by
bringing the two parts. g opposite the arms, the latter are prevented from
approaching each other, in which position of the parts the stopper can no longer
be withdrawn. The reverse operation, that is to say, when the arms of the spring

page_text: and the flat surfaces f¹ are brought opposite each other, the stopper can be with-
drawn by pulling it sufficiently to cause the arms of the spring to approach each
other.
In the modification represented at Fig. 8 the arrangement is the same as that
described with respect to Figs. 5 and 7, except that in order to move the spring
in relation to the locking block, I place on the body of the vessel a stop h¹. By
turning the stopper the locking block is turned with it, and its parts g are placed
opposite the arms of the spring as before described, that is to say, to prevent
them from approaching each other. If the stopper is turned so as to place the
flat parts of the locking block opposite the arms of the spring, the stopper
can be withdrawn as the arms of the spring can approach each other.
In the modification represented at Figs. 9, 10 and 11, I use a central screwed
rod on which is placed a nut j¹ furnished with two recesses to receive the
arms of the spring. As these recesses are made in inclined planes, it is only
necessary to screw or unscrew the rod by means of a key placed on the head /
to cause the stoppage of the arms of the spring. The descent of the nut permits
the approach of the arms of the spring towards each other, and this descent is
facilitated by means of a coiled spring m¹.
It will be understood that the forms, accessories, materials and dimensions of
my improved stopper may be varied without departing from the peculiar character
of my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. An arrangement of stopper which is retained in its socket e by means of
hooks or claws d at the lower ends of the arms of a spring e fixed within the
stopper, substantially as herein set forth and as illustrated in the accompanying
drawings.
2. In a stopper for bottles and other receivers, the combination with the stopper
body, of a spring having arms terminated by hooks or claws, and means for lock-
ing and unlocking said spring arms, substantially as herein set forth and as illus-
trated in the accompanying drawings.
