Improvements in cornets or similar musical instruments
Year: 1888

page_text: 1, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of Middlesex,
Consulting Engineer and Patent Agent do hereby declare the nature of this invention
to be as follows:-
In the Specification of a former Patent No. 295, dated January 7th 1886, granted
to Henry Harris Lake for "Improvements in cornets or similar musical instruments"
communicated from abroad by C. Mahillon, reference is made to and reasons aro
stated for the want of exactness of the sounds produced by brass wind instruments,
and resulting from the simultaneous depression of the several pistons or cylinders,
and an arrangement for obviating such want of exactness is described and illustrated;
the said arrangement consisting in providing the instrument with a regulating piston
to be operated by one of the free fingers of either the left or the right hand, according
to the form and construction of the instrument.
Now according to the present invention an arrangement is employed the nature of
which will be understood from the following description of an application thereof
illustrated by way of example in the annexed sheet of drawings and in which the
regulator instead of requiring to be operated separately is connected with the first
cylinder, and the lengthening of the additional tube B requisite for ensuring exactness
of sound is effected in an automatic manner.
When the third piston and cylinder are employed alone or conjointly with the
second piston and cylinder an additional tube A is connected with the first cylinder
at C and with the third cylinder at D so as to rejoin the column of air E F.
This additional tube A should be of a length corresponding to a lowering of one tone
and a half.

page_text: When the third cylinder and piston are employed conjointly with the first cylinder
and piston the additional tube A connects with the first cylinder at C; communicates
by reason of the distribution of air in the latter with the supplementary extension B,
and rejoins the column of air E F through D. By this invention all the advantages
enumerated in the former specification hereinbefore referred to are preserved but with
the further advantage that whereas the previous arrangement of regulating device
was to be operated by the performer the operation of the regulating device herein
described is automatic and independent of the performer.
As will be evident the present invention may be carried out in various forms to
suit the requirements of different applications. For example the additional tube of
the first cylinder might be made to pass through the extended body of the third
cylinder so as to produce by the combination of the two cylinders a result similar to
that above mentioned.

Improvements in Cornets and other Wind Musical Instruments.
I, WILLIAM LLOYD WISE of 46 Lincolns Inn Fields in the County of Middlesex
Consulting Engineer and Patent Agent 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:—
In the Specification of a former Patent No. 295 dated January 7th 1886 granted to
Henry Harris Lake for "Improvements in cornets or similar musical instruments
communicated from abroad by C. Mahillon reference is made to and reasons are
stated for the want of exactness of the sounds produced by brass wind instruments
and resulting from the simultaneous employment of the several pistons or cylinders
and an arrangement for obviating such want of exactness was described and illustrated,
the said arrangement consisting in providing the instrument with a regulating piston
to be operated by one of the free fingers of either the left or the right hand, according
to the form and construction of the instrument.
Now according to the present invention, an example of which is illustrated by the
two figures on the annexed drawing, the regulator, instead of operating separately,
forms part of the first cylinder and the lengthening which is requisite to ensure
exactness, is effected in an automatic manner.
When the third piston is operated alone or conjointly with the second piston air
passes through the branch A of the additional tubo of the third cylinder enters the
body of the first cylinder at C, passes directly into the bend D then into the branch E
and rejoins the column of air F. G.
This additional tubo A D. E has the exact length corresponding to a lowering of
one tone and a half. Each time however that the third piston is operated in con-
junction with the first piston, air passes through the branch A of the additional tube
and enters into the first cylinder at C, and then passes into the bend H (which is
longer than the bend D to a degree necessary to ensure the exactness of the lowering
required by the two additional tubes employed simultaneously) whence it passes to E
and rejoins the columu of air F. G.
By the present improvements all the advantages mentioned in the former
patent hereinabove referred to are retained with the further great advantage that
whereas in the former arrangement the regulator was designed to operate at certain
times at the will of the perforiner, by means of the present improvements the operation
of the regulator is automatic.
It is evident that the present invention may be carried into practice in other ways
than that shewn in the annexed drawing. For example the additional tube of the
first cylinder might pass through the extended body of the third cylinder and by the
combination of these two cylinders, produce the desired result.
It is also obvious that the additional tube A, D, E or. A, H, E, may be of other
forms than that shewn. Also that a tuning slide may be arranged upon one of the
branches A or E for the purpose of facilitating register.

page_text: Having now described and ascertained the nature of my said invention and in
what manner the same is to be performed I declare that what is claimed in cornets
and other wind musical instruments with pistons valves or cylinders is.―
1. The arrangement and combination with the third cylinder of the branches of the
additional tube traversing the body of the first cylinder substantially as described and
for the purposes set forth.
2. The arrangement and combination with the first cylinder of the branches of the
additional tube traversing the body of the third cylinder substantially as described and
for the purpose set forth.
3. Utilizing the holes in the pistons which afford passage for the column of
air F, G, for opening communication between the branch A and the bend H sub-
stantially as described.
4. The improved automatic arrangement for securing exactness in a wind instru-
ment constructed arranged and operating substantially as described with reference to
the drawings.
