I JOHN MANGER 26 & 27 Bartletts Buildings Holborn Circus City of London
Musical Box Importer do hereby declare the nature of this invention to be as
follows:-
Improvements in Toy Musical Boxes, for which a patent has already been granted
to me numbered 2241 & dated 1886 Feby. 16th. These improvements consists by
cutting two Slots or guides in the arbors or journals of the pin barrel or cylinder and
two corresponding Slots in the Blocks of Toy Musical Box plates; The plate of the
Musical Box is made with two blocks (metal) one at each end of the Comb which
are slotted to receive the pin barrel or cylinder that acts on the comb to produce the
tune and the slots in the arbor or journal fixed in the ends of this pin barrel or
cylinder guide it into the blocks in a certain position so that the pins in barrel or
cylinder do not come in contact with the comb.
As soon as the pin barrel is inserted a spring forces it in its place that it may
revolve regularly when put in motion.
The object of the spring is to slide the barrel or cylinder a given distance
horizontally so that the slotted parts of the arbor or journal may be removed from
the slots in blocks and the round pivotted parts of arbor or journal left to take equal
bearings in the revolution of the cylinder when playing the tune.

City of London 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 :-
The improvements claimed by me are shewn in following figures.
Fig. 1 is a vertical model of a Musical Box with front removed at line 1 & 2 as
shewn in Fig. 2.
Fig. 2 shews improvements as placed in Box with lid open.
Fig. 3 is an end view of movement shewing slotted supports.
The supports bb on plate a are made of one piece of brass or other metal, upon
which is fixed Comb c and screwed into Wooden Box xx.
The two supports bb are furnished with slots or mortices dd destined to receive
and support the Cylinder or pin barrel gg.
The design of slots or mortices d d are traced with a measurement or scale equal
to the slots pp in arbor or spindle tt and are further shaped with a guiding mortice d³
which prevents pins in barrel gg coming in contact with comb c during the operation
of changing a barrel or cylinder.
The support 6 has a spring fixed to it which presses pin-barrel g g into its proper
place immediately it passes through guiding mortice or slot d² and may be fixed to
cause barrel to slide to right or left.
The arbor or spindle tt has two differently shaped slots pp which are exactly equal
to slots d&d cut in supports or blocks 66 and these slots guide the pin barrel 99
in conjunction with spring so that it falls into its place proper before the comb c
and is ready to be played by turning handle m.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1st. The novel slotting of the arbor or spindles of Musical Box barrels.
2nd. The novel position and morticing or slotting of blocks or supports to guide
(in a secure manner) Musical Box barrels while being applied to the Musical Box so
that no damage is caused to the comb thereby.
3rd. The novel application of a spring or springs so that a barrel is thereby forced
into its proper place before the comb, without the aid of the operator.
Dated this 13th day of December 1887.
