IMPROVEMENTS IN REVOLVING STANDS FOR SHOW CASES AND THE LIKE
Year: 1884

page_text: 'I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex
Engineer do hereby declare the nature of the said invention for "IMPROVEMENTS
IN REVOLVING STANDS FOR SHOW CASES AND THE LIKE" to be as follows:-
The object of the invention is to provide a revolving show stand capable of.
supporting. a large load in proportion to its size while being so constructed that
it may be revolved with the least possible. power, and it consists essentially of.a
stand supported by a cylindrical case floating on water or other fluid contained
within a vessel, the revolving motion to the said cylindrical case being derived
from a clock movement or other suitable driving mechanism..
It is a well established fact that a hollow cylindrical case set in water supports
a load equal to its displacement while the power required to impart a revolving
movement to the said cylindrical case need only be of sufficient strength to
overcome, the friction of the water acting on the surface of the case; consequently
a cylindrical case can readily be designed to support any load, the dimensions of.
the case being simply increased to accomodate the weight to be carried and as the
weight so carried is supported entirely by the water a clock movement or other
mechanical power of little strength is sufficient and may be employed to impart to
the cylindrical case the desired revolving motion.
In carrying this invention into practice. a vessel of any suitable size and
preferably cylindrical in shape, is provided; also a hollow cylindrical case designed
to rest upon the water or other fluid contained by the vessel. This cylindrical
case, is preferably provided with a cone shaped bottom which projects below the
surface of the water in the vessel serving as a counterbalance to prevent any
undue tipping of the show, stand fixed to the top of the cylindrical case. If
required, shot or other ballast may be placed within the cone-shaped bottom so as
to more effectually carry out its object.
A tube encircles a hole made in the apex of the cone-shaped bottom, and extends
upwardly to a point above the level of the surface of the water so that the water
or other fluid within the vessel, cannot enter the case.

page_text: A smaller tube extends upwards from a hole which it surrounds in the bottom
of the vessel and protects the driving spindle and at the same time prevents the
escape of the water within the vessel.
An ordinary clock movement is fixed to the bottom of the vessel, The verge of
the clock movement is dispensed with and the ordinary escape wheel staff is
replaced by the driving spindle arranged to derive motion from the clock move-
ment and extending up through the inuer small tube from the top of which it
projects and has fitted onto it a head. The upper end of the driving spindle is
squared so that the head, fitted on to the squared end of the spindle may be
adjusted vertically on the said spindle but cannot revolve on it; therefore the
revolving motion imparted to the spindle, by the clock movement is conveyed to
the head, which being flexibly connected by cords or wires to the large. tube
conveys the movement of the spindle to the tube which being connected to the
case imparts the desired revolving motion.
It important that the head shall be flexibly connected to the large tube or to
some other part of the cylindrical case, as, the power of the clock movement is so
delicate that any friction other than that produced by the water supporting the
case would be fatal to the effective working of the machine.
The flexible connection permits any little lateral motion, while effectually
preventing the contact of any of the moving parts with anything calculated to
impede its movement. By fitting the head to the spindle so that it may be
vertically adjusted on the said spindle as described the vertical adjustment of the
case caused by the loading and unloading of the stand, will not in any way affect
the connection between the case and its spindle.
While this machine is designed specially for use in connection with show stands
it will of course be understood that the same device may be adapted for various
other uses. Its employment is not confined to the purpose herein specified.
It may be mentioned that although the foregoing description described the
device arranged to carry the load above the level of the floating case it will of
course be understood that the same effect can be produced so that the load can
be supported below the level of the floating case. In that case the spindle derives
its motion from a clock motion or some other motor power located above the
floating case. The head is similarly attached to the spindle, and is also flexibly
connected to the case by wires or cords.
Instead of the show stand located above the case I provide a stand or rack
suspended from the floating case below the vessel.

I ALFRED. JULIUS BOULT of 323 High Holborn in the County of Middlesex
Engineer do hereby declare the nature of this invention for "IMPROVEMENTS IN
REVOLVING STANDS FOR SHOW CASES AND THE LIKE," (a communication from
Samuel Thaddeus Culp of the City of Toronto in the dominion of Canada
Manufacturing Jeweller) 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 a stand or supporting platform in which the load is
supported by the displacement of water or other fluid whereby the stand sup-
porting the load may be caused to revolve by a power merely sufficient to overcome
the friction between the water and the stand; and the invention relates to
improvements in the connection between the driving motor and the stand it is
employed to revolve.
In the drawings
Figure 1 is a perspective view, of this apparatus showing a portion of one side
broken away to exhibit the conical bottom of the stand or platform.
Figure 2 is an enlarged detail, showing the manner of attaching the adjustable
head on to the driving spindle and flexibly connecting the said head to the tube
attached to the cylindrical case.
Figure 3 is a longitudinal section of Figure 1 with the top or platform
removed.
Figure 4 shows the arrangement of device when the load is supported below the
vessel containing the floating case. It also shows a weight arranged to impart a
rotary movement.
In figures 1-3 A is the outer vessel.
B is the hollow cylindrical.case designed to rest upon the water or other fluid
contained by the vessel A. This cylindrical case B has a cone shaped bottom C
which cone shaped bottom of course projects below the surface of the water in the
vessel A and serves as a counterbalance to prevent any undue tipping of the show
stand, D which is fixed as shown to the top of the cylindrical case B If required
shot or other ballast may be placed within the cone-shaped bottom C so as to
more effectually carry out the object of the said bottom.
P
E is a tube encircling a hole made in the apex of the cone shaped bottom C and
extending upwardly to a point above the level of the surface of the water so that
the water or other fluid within the vessel A cannot enter the case B.
F is a tube smaller than the tube E and extending from a hole which it
surrounds in the bottom of the vessel A This tube F is designed to protect the
driving spindle G and at the same time prevent the escape of the water within the
vessel A.
.
H is an ordinary clock movement fixed to the bottom of the vessel A The
verge of the clock movement is dispended with and the ordinary escape-wheel staff
is replaced by the spindle G which is arranged to derive motion from the clock
movement, and extends as before stated up through the tube F from the top of
which it projects and has fitted on to it a head I The upper end of the spindle G
is squared so that the head I which is fitted on to the squared end of the
spindle G may be adjusted vertically on the said spindle but cannot revolve on it;
therefore the revolving motion imparted to the spindle G by the clock movement
is conveyed to the head I which being flexibly connected by the cords or wires J
to the tube E as shown conveys the movement of the spindle to the tube E-which
being connected to the case B imparts.the desired revolving motion.

page_text: In figure 4 the driving movement is shown above the cylindrical vessel A the
load in this case being supported from a point below, the vessel A. In this form
of revolving stand the rod or cone C is supported by a top or bar extending down
through the tube F to a point below the bottom of the vessel A at which point
the platform or whatever is to be driven by the movement G is connected a head m
being formed on the rod or frame K.
.
.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First A cylindrical case B supported by water or other fluid and having
a hole centrally located in its bottom, and a tube E extending upwardly from
said hole, in combination with a tube F surrounding a hole in the bottom of the
stand or vessel A and extending upwardly into the tube E the tube F enclosing
and protecting the spindle G. for transferring motion-from the clockwork to the
carrying device substantially as and for the purpose specified.
Second: A cylindrical case B supported by water or other fluid contained
within a stand or vessel A the said vessel having a tube F extending upwardly
from its bottom to protect the spindle of the driving mechanism G as specified in
combination with a head adjustably connected with the bar or frame K to be
carried.
