  • Patent number: 4065194
    Abstract: A mechanism for automatically elevating or lowering a pulpit or lectern. A pulpit or lectern (hereinafter collectively "pulpit") is secured to the top of a rectangular box-like carriage. The carriage is guided during vertical movement along a plurality of guide rails by a plurality of pillow blocks secured to the carriage and engaging the rails. The rails are located within a pit which holds the pulpit and carriage when fully lowered. A vertical drive screw aligned with the center of the carriage and parallel with the guide rails engages a drive nut secured to the carriage. A reversible electric motor is adapted to drive the drive screw which moves the carriage between positions. The guide rails are adapted to guide the carriage and pulpit between a "down" position within the pit and an "elevated" position above the pit for use. Appropriate switches are provided to permit efficient operation of the system.
