the front end of the cavity to engage and stretch the
spring toward the rear end of the cavity and thereby
develop a latent force which when the player releases the
figure produces a thrust force as the spring resumes its
normal length to propel the figure into space whereby the
figure appears to be flying without any visible means of
propulsion.
Uhrig's invention relates to "a springing and dancing
puppet which first stands still and then after a certain time
springs high of itself" (lines 10-13). As shown in Figure 1,
Uhrig's invention includes (1) a box 1 provided with a border
b, a bottom c and a pin d; (2) a puppet h provided with a tube
e in which a spiral spring g is arranged; and (3) a rubber
ring f provided on the tube e. Uhrig's invention operates
(see lines 20-25) by
(1) pressing the tube e of puppet h down over the pin d so
that rubber ring f is below border b, thus compressing spring
g;
(2) permitting the rubber ring f to gradually proceed upwardly
through the border b; and (3) upon the rubber ring f passing
the border b, the puppet h springs high.
