COMPLETE SPECIFICATION.
An Improved Device for Holding Articles in Place upon Tables or
other Supports.
We, HARALD PALME, of Ronnebygatan 48, Karlskrona, Sweden, Commander in
the Royal Navy, HERMAN SKANTZE and HUGO SKANTZE, both of Bredgatan 2,
Karlskrona, Sweden, Gentlemen, 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 present invention relates to an improved device for holding in place, more
especially on board ship in a rough sea fumblers, bottles, plates or other articles
standing on a table, so that they will not slide off and get broken. The device is
based on the long known use of the vacuum which may be created between a
flanged rubber plate or the like and a surface against which it rests to hold an
article in place by suction.
In the accompanying drawing
Figures 1 and 2 show the holder in central vertical section in two different
positions, before and after the suction being produced.
A is a ring or case closely enveloping the edges of a rubber plate B, preferably
shaped as shown in the drawing, the bottom edge of which is on a level with
or projects slightly below the bottom edge of the said ring or case A. This
plate B may be of uniform thickness, though preferably its middle portion should
be made thinner. At the underside of the central portion of this plate is a
disc C, which is connected with a receptacle D, rotatable relatively to the ring or
case A, either made in the form of a drinking vessel, for instance a goblet, or
serving to hold a tumbler on the like placed within it. In the said receptacle
above the case A, is located a sliding hottom E provided at its underside with
bent lugs F, slanting or inclined at their underside and bearing against pro-
jections G formed on the inner side of the receptacle D, or this arrangement may
be reversed. The sliding bottom E is connected with a stud or stem projecting
from the disc C so that the disc C participates in the motion of the bottom E,
but the said sliding bottom is not rotatable relatively to the case A and plate B.
Between the case A and a collar on the stem of the disc C is inserted a spring H,
tending to force the disc together with the elastic plate B outward from the
case A.
When it is desired to secure the holder to a table or the like, it is first pressed
against the same, the parts being in the position shown in Figure 1, and then
the receptacle D is rotated relatively to the case A and plate B in such a manner
that the projections G will slide along the slanting underside of the lugs F
thus lifting the bottom E together with the disc C attached thereto, a vacuum
being thereby produced between the central portion of the plate B and the table
or other surface against which it rests. The parts now assume the position
shown in Figure 2 and the holder will be held in place by the pressure of the
surrounding atmosphere.
When it is desired to release the holder, the receptacle D is rotated in the
reverse direction so that the projections will no longer prevent the bottom E

page_text: from descending under the influence of the compressed spring H and at the same
time drawing down the central portion of the elastic plate B so that the vacuum
disappears.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
An improved device for holding in place articles placed on tables or other
supports, comprising a case (A) closely enveloping with its lower edge an elastic
plate (B), a disc (C) resting against the elastic plate (B) and connected with a
sliding bottom (E) of a receptacle (D) rotatable relatively to the case (A) and
provided with projections (G) engaging with inclined lugs (F) located at the
underside of the said sliding bottom (or vice versa), substantially as hereinbefore
described and for the purpose specified.
