Importer do hereby declare the nature of this invention to be as follows:-
Hitherto in Toy Musical Boxes-The Cylinder or Barrel on which the pins are
placed has been a fixture. Appicants methods of interchanging same is 1st by
placing two slides 1 on either side of comb so that Cylinder Slides into its position
& is fixed there by 2 springs resting on spindle.
2nd By making one of the present pillars used in Toy Boxes moveable on a
pivot so that new Cylinders can be put in & taken out easily.
3rdly by passing a rod through the present pillars passing through centre of
cylinders & fixing same in its place.
The Cylinders in each case must be prepared in a new & special way to facilitate
either of above 8 named methods.

I, JOHN MANGER of 26 and 27 Bartlett's Buildings Holborn London E.C.
Musical Box Importer, 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 :-
This Invention relates to Toy Musical Boxes of the kind known in the Trade as
"Manivelles" by reason of their being turned by a small crank handle.
Heretofore the playing capacity of said Musical Boxes has been limited to a
single tune, and this Invention has for its object to render the pin barrels of said
musical boxes easily interchangeable so that one box can be made to play any
desired number of tunes.
The Invention consists in making the barrel removable from its bearings.
Reference is to be had to the accompanying drawings forming part of this
specification which represent three different ways of carrying out the object in
view. The drawings show the mechanism removed from the external case, which
latter may be of any desired form and arrangement. The same letters of reference
indicate the same parts in all the figures.
B is the pin barrel, C the comb, and S the tangent screw or worm gearing with
a ring of teeth on the end of the barrel, these parts being combined for operation
in the usual way.
Figure 1 is a plan, and Figure 2 an elevation of the mechanism of a musical box
in which the journals which are fixtures in the ends of the barrel B instead
of being received in permanently closed bearings are mounted in slots a in the
blocks A cast or fixed on the base and are retained therein by latches E pivoted
at e to the blocks A and engaging with the ends of the journals b which project
beyond the blocks A as shown. By throwing back the latches E as shown in
dotted lines in Figure 2. the barrel may be readily removed from its bearings as
shown in dotted lines and another inserted. The slots a should be approximately
perpendicular to the tangent screw S and in the plane of the comb C to enable
the barrel to be slid into place without injury to the worm and pins.
Figures 3 and 4 show views similar to the above described but in which the
latches E instead of being pivoted are formed or carried by springs fixed to the
bearing blocks A as shown, these spring catches engaging with the journals bas
before and being readily released when desired to change the barrel.
Figures 5. and 6. show plan and elevation of musical box in which the barrel
axis is received in the ordinary closed bearings (ie the blocks A have holes through
them instead of open slots) but the axis is constituted by a loose rod D passing
through holes in the ends of the barrel and completely traversing the barrel and
bearings, the rod being easily withdrawn as shown in dotted lines for the purpose
of changing the barrel.
Figure 7 shows a plan of a musical box in which the barrel turns between
coned centres received in holes in the ends of the barrel, the one bearing block A

page_text: being movable on the base by being pivoted at a so that it may be swung back as
shown in dotted lines for the purpose of enabling the barrel to be withdrawn or
inserted.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed I declare that what
I claim is;
The respective modes of mounting the pin barrels of toy musical boxes removably
in their bearings substantially as herein described and illustrated in the respective
figures of the drawings.
