and other Articles or Goods.
We, BERTRAND HAMBURG, Merchant, PAUL KETTERER and EDUARD KETTERER,
Watchmakers, all of Frankfort-on-the-Main, in the Empire of Germany, do hereby
declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to apparatus for displaying watches, jewelry and other articles
or goods.
The apparatus constructed according to this invention is designed to cause articles
or goods placed upon it to automatically pass in succession before the eyes of
spectators.
Whereas in the apparatus heretofore employed the articles or goods displayed turn
continuously upon a vertical axis; they are rotated upon a horizontal axis in this
improved apparatus and the latter differs essentially from the former in that its
movement is not continuous but intermittent and thus affords the spectators a better
opportunity for looking at the articles or goods displayed.
In the accompanying drawings
Figure 1 is a side elevation of the improved apparatus with the casing shown in
section, and
Figure 2 is a plan of the same, the casing being likewise shown in section.
Figures 3 and 4 represent parts of the mechanism used in the said apparatus.
Figures 5, 6 and 7 show modifications of the mechanism constructed according to
this invention.
The operative parts of the apparatus are enclosed in a casing A which has at its front
side an opening of such size that only the articles or goods which are intermittently
displayed can be seen through it. The articles or goods are fixed upon tables T which
are placed radially and connected with each other (Figure 1). These connected tables
are supported by journals Z in brackets B, and constitute vanes or wings adapted to
turn upon a common axis

page_text: Upon the journal on the right hand side of the tables is arranged a small toothed
wheel E, whilst upon the journal on the left hand side is placed a disc F which is
provided at its periphery with slits a.
The toothed wheel E engages with a toothed wheel C supported in the said
bracket B and firmly connected with a ratchet wheel D. Upon the shaft carrying
these wheels is pivoted a lever H the extremity of which is bent to an angle and which
is arranged to be drawn downwards by the spring G. A pawl K on the lever H
engages with the teeth of the aforesaid ratchet wheel D (Figure 1).
A lever L having its fulcrum at J on the bracket B on the left hand side of the
said tables is pressed by a spring M against the disc F so that when this disc turns
the front end of the lever will snap into one of the slits a formed therein, and com-
pletely arrest the disc together with the tables T.
The apparatus is set in motion by any suitable clockwork U. A disc S which is
arranged to be rotated in the direction of the arrows shown in Figure 3, carries four
pins N. Upon the plate P that closes the clock work on this side is pivotted at V the
double-armed lever Q. In the revolution of the disc S the arm of the lever Qin
proximity to the disc will be pressed downwards, whilst the lever arm on the other
side of the fulcrmin V will be raised. The latter arm lifts one end of the lever Land
disengages it from the disc F, as indicated in dotted lines in Figure 4, so that this
dise and the tables T, connected therewith can turn freely.
Simultaneously with the disengagement effected in this manner the lever H is raised
in the rotation of the disc S by a second pin N, thereby stretching the spring G. If
now in the further rotation of the disc S the lever H leaves the aforesaid pin, it is
drawn downwards again by the spring G. In this descending movement the pawl K
on the lever H will engage with one of the teeth of the ratchet wheel D so that the
latter and the toothed wheel C connected with it are caused to make a partial revolu-
tion which is transmitted through the toothed wheel E to the journals or axis of the
tables and therefore to the latter. When these tables have made a third of a revolution,
the lever L, which has in the mean time been released again, snaps into a slit a in the
disc F and arrests this disc together with the tables T, thus effecting a stoppage in
their rotation until the following pins on the disc S cause the same described operation
again.
This operation is again and again repeated in the same manner so as to successively
display the articles or goods which are secured on both sides of the tables T.
The
A modification of the lever mechanism which effects the intermittent revolution of
the aforesaid tables is represented in Figures 5, 6 and 7. Also in this case the
apparatus can be set in motion by any clock work U of suitable construction.
disc S¹ provided with the pins Ni does not turn continually as in the above described
arrangement, but intermittently, the partial rotation of the same taking place each
time through a distance equal to that of one pin N¹ from the other. The revolution of
the disc S is effected in the direction of the arrows shown in Figure 5, the levers Q¹
and H¹ being at this point pressed downwards by the pins N¹, as indicated in the same
figure by the arrows 1. The lever H¹ is connected with the lever H2 by a cord V¹
passing around a pulley R¹. If in the rotation of the disc S¹ one arm of the lever H
is pressed downwards by a pin N¹ the other arm of this lever will pass upwards. As
however the last mentioned lever arm is connected with the lever H by the cord that
passes around the pulley R¹ the lover H2 having its fulcrum at 0¹ in the bracket B, is
drawn down in the upward movement of the said lever arm. The pawl K on the
lever H2 will then engage with one of the teeth of the ratchet wheel D₁ and cause the
latter and the toothed wheel C which is firmly connected therewith, in the downward
notion of the lever H2, to make a partial rotation, this movement being transmitted
to the tables T by means of the toothed wheel C¹ and the toothed wheel E' which
engage with each other. By the spring G¹ secured to an arm W the lever H² is drawn
upwards again as soon as the traction ceases.
Every time when the lever H2 moves downwards, the tables T will perform a third
of a revolution, so that two fresh sides of the tables with the articles or goods arranged
upon them will become visible through the opening in the casing which surrounds the

page_text: apparatus. Before one arm of the lever H¹ is pressed downwards by a pin N¹ on the
disc S', an arm of the lever Q pivoted at V is also pressed downwards by a second
pin, whereby the lever L which is arranged to arrest the tables T is disengaged in the
same manner as in the first described arrangement. The construction of this dis-
engaging device is similar to that described with reference to Figures 1 to 4 and
differs from it only in that a counterweight M' is arranged on the rear end of the
lever L to act upon it, whereas in the other arrangement the lever L is pressed
upwards by a spring M.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
First An apparatus for displaying watches, jewelry and other articles or goods in
which tables (T) arranged radially upon a common horizontal axis and receiving the
articles or goods to be displayed are from time to time caused to make a partial
revolution so that the said articles or goods will intermittently pass in succession before
the eyes of spectators.
Second The mechanism which imparts an intermittent movement to the tables (T),
consisting of the disc S provided with the pins N and set in rotation by a clockwork,
in combination with the levers Q, L and disc F on the one hand, and the lever H,
spring G, toothed wheels C and E ratchet wheel D and the pawl K on the lever H on
the other hand (Figures 1 to 4).
Third A modification of the mechanism which is characterized in the second
claiming clause consisting of the disc S¹ provided with pins N¹ and set in inter-
mittent rotation by a clockwork, in combination with the levers QL and the disc F
on the one hand and the levers H₁ H2, the spring G₁ secured to the arm W, the
toothed wheels C¹ and E¹, ratchet wheel D¹ and the pawl K'arranged on the lever H²
on the other hand (Figures 5 to 7).
