Improvements in Mouth-pieces for Cornets and kindred Musical
Instruments.
I, CHARLES ARTHUR ALLISON, of 52 Chancery Lane, London, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Benjamin Witmer, of the Village
of Plattsville, in the County of Oxford, in the Province of Ontario, Dominion of
Canada, Painter, and Eri Whaley, of No. 158 Yonge Street, in the City of
Toronto, in the County of York, and said Province of Ontario, Dominion
cf Canada, Music and Musical Instrument Dealer), 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 particularly to improvements in mouth-pieces for cornets:
and other musical instruments in which sound is produced by blowing into the same..
The object of the said invention is to produce a mouth-piece by which the higher
tones can be easily produced by simply pressing the cushioned mouth-piece harder-
against the lips, instead of by a peculiar and acquired formation of the lips
heretofore.
In the accompanying drawing illustrating this invention, similar numbers of
reference refer to similar parts throughout the different figures, and
Fig. represents a central section of the lip-ring shown twice the natural
size.
Fig. 2 represents the moving sleeve on which said lip-ring is carried, said moving-..
sleeve being also shown twice natural size.
Fig. 3 represents the body of the mouth-piece similarly enlarged and in detail
central section.
.
Fig. 4 represents also a central section twice enlarged, of the adjusting-ring
employed, and
Fig. 5 represents a central longitudinal section of the mouth-piece complete.
and drawn to the natural size.
The improved mouth-piece consists entirely of the body or shank piece 1,.
moving-sleeve 2, lip ring 3, adjusting-ring 4, and spring 5, adapted to fit and work
as hereinafter more fully described.
The shank-piece 1 resembles the ordinary mouth-piece at the end 6 where it is.
adapted to fit into the tapered interior of the instrument to which it is applied;
but at its opposite end 7 it is cylindro-conoid externally, and on the tubular portion
of the shank piece a thread 8 is formed to receive the adjusting-ring 4 which
bas an adapted thread 9 internally to fit over said thread 8 on the shank-piece 1.
The moving-sleeve 2 has a chamber 10 at one end to fit neatly over the cylindro-
conoid end 7 of the shank-piece 1 and is slightly longer so as to allow of the said
end 7 moving reciprocally within the chamber 10 when operated in producing the
higher tones. The smallest centre chamber 11 fits over the shank-piece 1, and
the chamber 12 at the opposite end is adapted to receive the spring 5 and that
portion of the adjusting ring 4, enclosing the said spring 5 to shield and cover the
said spring 5. On the exterior of the chamber 10 is formed a thread 13 adapted
to receive the lip-ring 3 screwed thereon.
.
The lip ring 3 is internally threaded as already specified and has an internally
projecting flange 14 which forms a stop to prevent the thin edge of the end 7 of

page_text: the shank-piece 1 projecting and injuring the mouth of the musician when the
mouth-piece is fully compressed.
The adjusting-ring 4 is internally threaded to fit the thread 8 on the shank-
piece 1 and it has a sleeve 15 projecting as shown which is adapted to enclose the
spring 5 and also to pass within the chamber 12 and assist the same in forming a
shield over said spring 5.
The spring 5 is a simple cylindrical or rising spiral of suitable metal and bears
at its opposite end on the moving-sleeve 2 and the adjusting-ring 4, and it
normally holds the moving-sleeve 2 extended t, full extent over the end 7 of the
shank-piece 1.
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 :-
Claim 1. In a mouth-piece for cornets and kindred musical instruments, the
combination of the shank-piece having an enlarged cylindro-conoid shaped end,
the moving-sleeve fitted over the shank-piece and the lip-ring screwed on said
moving-sleeve, and having a stop flange therein, substantially as shown and
described.
Claim 2. In a mouth-piece for cornets and kindred musical instruments, the
combination of the shank-piece having an enlarged cylindro-conoid shaped end,
the moving sleeve fitted to slide on the shank-piece, the lip-ring screwed on the
said moving-sleeve, and having a stop flange therein, and the spiral spring
encircling the shank-piece and normally holding the moving-sleeve extended over
the end of said shank-piece to full extent, substantially as shown and described.
Claim 3. In a mouth-piece for cornets and kindred musical instruments, the
combination of the shank-piece having a cylindro-conoid shaped end, the moving-
sleeve fitted over and sliding on the said shank-piece, the lip-ring screwed on said
moving-sleeve and having a stop flange within, the spiral spring encircling said
shank-piece and bearing against the moving-sleeve, and the adjusting-ring screwed
on the said shank-piece to secure and shield said spiral spring, substantially shown
and described.
