BOXES AND OTHER MUSICAL INSTRUMENTS IN WHICH ARE USED ONE OR MORE
REVOLVING CYLINDERS OR BARRELS." [A communication from abroad by Auguste
Paillard, of St. Croix, in the Republic of Switzerland.]
The object of this Invention is to afford greater facilities in the fitting of cylinders
to musical boxes and other musical instruments by allowing of such cylinders being
made without the necessity of the maker having the musical boxes or other instru-
ments by him for the purpose of fitting the cylinders thereto, being thus enabled to
furnish musical boxes and other instruments with new and different cylinders in
any number without the necessity of removing, such instruments from the custody
of their owners. For this purpose I apply pressure in a horizontal direction, and in
a line with the axis of the cylinder at one or more points at or near one of the ends
of the same.
I prefer to apply this pressure by means of helical springs placed
over pins projecting horizontally from a wheel or any convenient part of the
nechanism, and bearing against a disc fixed on to the central spindle of the revolving.
cylinder, such springs always exerting sufficient pressure in a horizontal direction
to keep the cylinder well up to its bearings, and free from play or looseness between:
the same; therefore by reason of the springs keeping the cylinder in one fixed.

page_text: position, the number and size of the instrument being known, new cylinders may
at any time be provided for such instrument without the necessity of such exact
fitting as to render unavoidable the removal of the instrument to the manufactory.
By means of this Invention musical boxes and other instruments may be provided
at any time with new and interchangeable cylinders without any inconvenience to 5
the possessors of the instruments.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Manger in the Great Seal Patent Office on the 31st August

Having now described the nature of my Invention and the manner in which the
same is to be performed, I wish it to be understood that I do not limit myself to
the precise details herein-before described, as the same may be varied without
departing from the nature or principle of my said Invention; but I claim as my
said Invention the means of affording greater facilities in the fitting of cylinders to

any mere variation or modification.
In witness whereof, I, the said John Manger, have hereunto set my hand
and seal, this Thirtieth day of August, in the year of our Lord One
thousand eight hundred and seventy-eight.
