Improvements in and in connection with Mechanical Musical
Apparatus.
I, THOMAS RICHARD SHILLITO of 89 Chancery Lane, London, WC, Engineer
and Patent Agent, do hereby declare the nature of this invention-a communication
to me from abroad by Otto Spaethe of Gera (Reuss) Germany, Manufacturer-
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 firstly to means in mechanical musical apparatus for
directly actuating a damper for regulating the tone of the music whilst this is
being played and also to a bell drum or tangle playing mechanisu actuated
direct from the travelling perforated note sheet of a mechanically played musical
Instrument This first poition of the invention is shown in Figs. 1 to 11 of the
diawings in which
Figs. 1 and 2 are cross sectional views of the damper respectively in the
engaged and disengaged position and
Figs. 3 and 4 respectively a side view and a plan of the damper.
The damper the function of which is to regulate the distance froin the strings to
which the haminers are raised by the note sheet compuses two strips 11' of wood
or other light mateual the former being covered with felt 1" the latter having two
perpendicular extensions 1 The two stups are connected together by two
screws 2 2 and ate so arranged that the distance apart of the strips may be varied
Extensions or
by these screws to adjust the damper action to the required tones
brackets 11 selve for communicating through wire pins 4 fixed to the augle
levers 3 movement to the damper which movement is as shewn obtained by the
travelling note sheet alternately engaging by ceitam of its perforations the
points 31 of angle levels 3 55 (Figs 34) are pins upon which the damper is
cared in the sides of the instrument casing so as to rest somewhat obliquely.
21 are strings.
20 is one of a row of banimeis mounted to turn on a spindle 22.
Figs 5 to 11 illustrate the bell drum and triangle playing action as communicated
from the motive power direct such as a travelling perforated note sheet or a
revolving pin drum. The action is obtained by means of keys such as indicated
by 6 which is counected by an oscillating lever 7 through a band 7. At the head of
lever 7 there is a head 711 for striking the corresponding bell dium or triangle.
The numerals 8 8 indicate the perforations in the note sheet which actuate the
damper and the numerals 9 91 those which actuate the bell drum or tangle
mechamm. The key is or keys 6 are mounted upon the long fixed spindle 6' to the
tooth 6 being engaged by a perforation in the note sheet so as to turn the key
upon the said spindle and pull on the band 7' to lift the striking lever 7 which
when the note sheet releases the tooth will drop down. In this case the bell dium
and tangle come outside the note sheet so as to allow of a free passage io the
latter on the bands 7' are made sufficiently long for the purpose
When the level 7 is raised the piece of we engages with the haminer head
as shewn at Figs. 7 9 & 5 and prevents the hammers tiom being moved by the
note sheet.
The arrangement of the damper and bells dium and triangle mechanism in the
music works is designed in the manner that two angle levers 3 for actuating the
damper are placed right and left one near each end of the damper and therefore
all the keys come between said angle levers whilst the keys for playing the bell.
.

page_text: drum, and triangle are distributed to correspond therewith, but the arrangement
of the keys in a particular way is not obligatory, but may be left to the judgement
of the particular constructors as also may be the number of the bells, drums or
triangles employed.
The invention relates secondly to the construction of an advertising apparatus in
connection with the door or hd of the mechanical music works and driven by the
same motive power as the intter. The arrangement is shown in clevation and plan in
Figs 12 and 13 and the essential feature is, that with the door of lid in the closed
position the apparatus is set in notion and by opening the door the working of the
apparatus is stopped. This essential feature may be obtained in different ways.
By way of example, rollers 10", 10111, are mounted in brackets behind an opening
in the door. These rollers carry an endless band upon which advertisements, show
cards, etcetera may be fixed. The mechanism through which power is transmitted
to the advertising band, is within the casing It consists of wheels 11, 111, 11",
which for the purpose of noiseless running may be made of india iubber or other
suitable material. 12 is a spindle on which is fixed a band pulley 13 which being
set in motion drives the whole apparatus.
14 is the intermediate spindle carrying
the intermediate or connecting wheel 11' Rollers 10, 101, may be brought out
with the door to facilitate the exchange of advertisements etcetera. In closing the
door wheel 11 comes into engagement with wheel 11' and the endless advertising
band is thereby set in motion In opening the door (Fig 13) wheel 11 of
advertising roller 10 comes out of engagement with the driving mechanism and
the advertising band is stopped.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In mechanically played music works of the kind referred to the arrangement
of a damper by which during the playing of the instrument the toue may be
suitably regulated, substantially as described with reference to Figa 1 to 4 and 11
of the drawings.
2. lu music works of the kind referred a bell, drum and triangle playing
mechanism actuated direct from keys, substantially as described with reference
to Figs. 5 to 11 of the drawings.
3 in combination with the mechanisms claimed In Claims 1 and 2 the
application of a note sheet so perforated that during the playing of the music
works, it alternately actuates on the one hand the bell, drum and triangle playing
mechanism and on the other hand the damper substantially as described and
shown.
4. In combination with a mus works of the kind referred to the advertising
appaintus which is set in operation in closing and stopped in opening the door
old of the instrument, substantially as described with reference to Figs. 12
and 13 of the drawings.
