Pendulum device

A kinetic sculpture apparatus comprising:

• a base provided with a receiver containing a fine, particulate material presenting a bed thereof;
• a pendulum having an upper end and a lower end, the latter presenting a scribe;
• a standard on said base extending upwardly therefrom;
• a support arm above said base extending over said bed and mounted on said standard for pivotal movement about a generally horizontal axis;
• means suspending said pendulum from said arm with said scribe contacting said material, and establishing a primary horizontal axis of swinging movement of the pendulum,
• said upper end of the pendulum being provided with a secondary coupling connecting the pendulum to said suspension means,
• said scribe having a tapered tip normally penetrating said bed of material;
• and
• elevational control means connected with said arm for holding the same in a selected position to control the height of said pendulum and thereby set the depth of penetration of said tapered tip, whereby the depth and width of the lines of sculptured patterns made in the bed of material as the pendulum swings may be controlled without interrupting the pendulum's movement.

A kinetic sculpture apparatus comprising:

• a base provided with a receiver containing a fine, particulate material presenting a bed thereof,
• a pendulum having an upper end and a lower end, the latter presenting a scribe,
• means suspending said pendulum over said base with said scribe contacting said material, and including a rocker element on said upper end of the pendulum and a support element cooperating with said rocker element to establish a primary horizontal axis of swinging movement of the pendulum,
• one of said elements having a pair of horizontally spaced projections each provided with a pointed tip,
• the other of said elements having a number of spaced sockets arranged in a horizontal pattern providing alternative pairs of said sockets capable of receiving said tips,
• said tips being received in a selected pair of said sockets to present a pair of low friction, point bearings defining said axis, and
• said upper end of the pendulum being provided with a secondary coupling connecting the pendulum to said rocker element, whereby a sculptured pattern of particular configuration is made in the bed of material by the scribe depending upon the location of said axis determined by the selected sockets and the position from which the pendulum is released relative to said axis.

A kinetic sculpture apparatus comprising:

• a base provided with a receiver containing a fine, particulate material presenting a bed thereof,
• a pendulum having an upper end and a lower end, the latter presenting a scribe,
• means connected to said upper end for suspending said pendulum over said base with said scribe contacting said material whereby, when the pendulum is in motion, the scribe makes a sculptured pattern in the bed of material,
• said means including a plurality of individually selectable primary horizontal axes of swinging movement of said pendulum,
• said pendulum including a removable weight at its lower end provided with said scribe, and
• a setup device having means for attaching the device to said pendulum when said weight is removed,
• said device being provided with a blunt bottom in contact with said material when said device is attached to said pendulum, whereby to smooth and shape the bed of material for subsequent sculpture by operating the pendulum with the device attached to thereby impart a concave configuration to the surface of said bed most appropriate for the selected primary horizontal axis.

• means suspending said pendulum over said base with said scribe contacting said material, and including a rocker element on said upper end of the pendulum and a support element cooperating with said rocker element to establish a primary horizontal axis of swinging movement of the pendulum, and
• said upper end of the pendulum being provided with rotary coupling means connecting the pendulum to said rocker element, whereby a sculptured pattern of particular configuration is made in the bed of material by the scribe depending upon the position from which the pendulum is released relative to said axis,
• said rotary coupling means including a loop component on said upper end of the pendulum and an annular component receiving said loop component and said rocker element,
• said annular component having a beveled inside surface presenting a relatively sharp, continuous inner edge in engagement with said loop component and said rocker element and cooperating therewith to provide an antifriction connection therebetween.
