IVAN VAUKONOWSKI 73 Carlton Road Kentish Town, London, Professor of Music
JOHN ALLBERREY 73 Carlton Road Kentish Town London Joiner do hereby declare
the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
Magnet attached to horizontal movable arm (A) connected with a tube (B) which
revolves in another tube (C). The bottom of the revolving tube has a double pulley
wheel attached (D). The whole is set in motion by a chain passing round the wheel
and connected with a wood pedal (E). Under the wheel is a lifting drum (F). The
book is placed on the stand of the apparatus, a metal clip (G) is attached to each leaf,
by pressure on the pedal the arm and magnet move round to the leaf, attraction takes
place, the foot of the party engaged is raised slightly on the pedal and the magnet
returns with the leaf to the left, strikes against a bar (H). The lifting drum then
raises the revolving tube and releases the magnet for repeated action. Apparatus
supported on three legs (I J K). The lifting drum (F) is in two parts, the bottom
part is fixed to a guard-the guard is fixed to the outer tube above the double
pulley wheel (D).
The upper part of the lifting drum is fixed to the double pulley wheel (D) and the
latter is fixed to the tube (C) and by connection with the pedal the upper part of
the lifting drum and its attachments revolve and cause the apparatus to act. The
bottom part does not move at all.
This apparatus is to be made either with brass or zinc tubes and can be adapted
either to piano, harmonium, American, church or any other organ, and cau be
regulated to any height for any other instrumental practice.
