Improvements in English Slide Trumpets for Producing Extra
Notes and to Facilitate Tuning.
I WILLIAM WYATT of 123 Portman Buildings, Marylebone N.W. in the County of
Middlesex (Musician) do hereby declare the nature of this invention to be as
follows:-
I construct of metal a trumpet with a double slide, which obviates all defects of the
old slide trumpets, adding to its compass, 5 notes never to my knowledge attained
before on any slide trumpet. Thus making it a perfectly true instrument (chromatic)

retaining the tone of the old trumpets, with greater facility for execution, and
retaining the old style of crooking, riz. in F, E, Eb, D, Db, and C.
These extra notes, are only procurable with a double slide. Which slide when
worked, in the usual way, with the fingers, gives 21" (21 inches) more length than
the set length of the trumpet.
This double slide enables a player to produce in perfect tune, any note either
semitone or tone, between its extreme compass viz.
which has never before been done on the English slide trumpet (to the best of my
knowledge and belief). The English slide trumpet being deficient of the following
notes
The object of my invention is to get these notes on the slide trumpet.
This invention relates to a greater length of slide (when worked by the fingers)
which I obtain by means of the double slide, which double slide when extended its

effect, I will describe the following sheet of drawings, reference being had to the
letters and figures marked thereon.
K bell, and C, D slide are identical with the old slide trumpet.
A. B is my new added slide, connected to the old slide by small stays at 1. 2. 3.
when the slide is worked in the usual way, viz. by pulling with the fingers the cross
bar H as far as the stop M. it extends the double slide 58" (58″ inches) which makes
an extra 214" inches to the set length of the trumpet. The center action H H. H. M
and F are also identical with the old trumpet.
The tube E. E. is blank, i.e. no air passage, but is used as a stay and support to
cross stay F. and is connected to the tubing of instrument by fitting and soldering at
the points O2 & P. The turn R is turned up to allow the fingers room to work the
slide H H.
The arrangement of the double slide tubes are shown in section taken at Y.
of which A B is the new added slide, and C. D is the old slide, the entrance tube O is
old, as far as T but this bend W is new and also the connection to my new slide at S.
Fig. 2 is a drawing of the old C crook viz. all stiff and rigid. The Dy and D crooks
are of the same shape, and of the usual length to put them in their proper keys.
My.improved method of tuning the instrument when crooked in either of these
3 keys, is by making these crooks with a sliding limb as at X¹ Fig. 3. the length of the
slide being regulated by the length of the crook. The other crook viz. F, E, Eb when
put in the instrument are tuned in the usual way viz. by adding short bits.

Improvements in English Slide Trumpets for Producing Extra
Notes and to Facilitate Tuning.
I WILLIAM WYATT of 123 Portman Buildings, Marylebone N.W. in the County of
Middlesex (Musician) 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 slide trumpet, has hitherto been made with a single sliding tube, by the
lengthening and shortening of which, certain notes. are obtained on the instrument.
But the length of tube obtained, by this single slide, is not sufficient to make it
a perfect chromatic. instrument. There being some notes in its lower register,
unattainable.
This invention, relates to a construction of trumpet, whereby I obtain these omitted
And also to extend its compass downwards.
notes.

page_text: I have therefore added a 2nd slide to the instrument for that purpose which is
connected to the usual single slide, and worked by the fingers in the usual way,
thus doubling the length of tube, when extended by the fingers.
And in order that my invention may be fully understood, and readily carried into
effect, I will describe the following sheet of drawings, reference being had to the
letters, and figures, marked thereon.
Fig. 1 is a perspective side view of a trumpet, according to this invention, and
Fig. 14, is a section of the slides and center action taken at Y.
K bell, C. D slide, and centor action H H. M. H. and F, are the same as in the
single slide trumpet, except that I have made the slide C. D. a trifle longer, and have
moved the finger bar H, nearer to F.
To increase the length of shift. The tube E. E. is in its usual. position, as on the
single slide trumpet. But I use it here for a different purpose, in the single slide
trumpet it is a part of the air passage.
But in a trumpet constructed according to this invention, it is a blank tube, i.e. no
air passage. But is used as a support to the cross stay F. And to strengthen, the
instrument generally, it is fitted and solderd to the bend R, at the points P. and. 03.
Which point 02 is a connection to my new added slide; and the point P is at the
junction of the new bend R, and the old slide D.
my
The slide C. D. is the old single slide, of which, X and X are the inner tubes,, and
C. D. are the outer tubes, and is the same as the single slide trumpet, except that. I
have made the slide C. D. longer to meet the requirements of invention.
The bend R is also needed to be turned up as per drawing but only sufficient to allow
the fingers, and the finger bar H, to pass under to the stop M. I then construct my
new added slide of the same sized tube, and the same width, of which X and X' are
the inner tubes, and A. B. the outer tubes, the new bend' W continuing from the
slide B at S, and is carried on the top of the slide A, where each of these 3 tubes,
viz. O. T, A & C are connected together, by the-4 stays between them. Thus making
that side fixed and rigid to the bell K.
The new outer slide B is connected to the old outer slide D at the points 1, 2, 3,
which, 3 connections holds the 2 slides firmly together, thus making them double
(or having sliding limbs instead of 2 as hitherto).
Thus when the finger bar H, is pulled, it extends at once; and at the same time, the
double slide. (The drawing represents the slides when extended about halfway.)
Now the vital addition in a trumpet, constructed as herein shown, is to get 211"
(21 inches) more length of tube, when extended, over and above the slide when in its
normal position, and this I obtain by fixing the finger bar H, at a distance of
5" from the stop M. Then when the slides are fully extended I get the 214",
viz. 53" x 4214". Then by the full extension of this double slide, I am enabled to
get the low E before mentioned, and also the Ab.
A less length of slide than this 214", will not give the result desired, viz. a perfect
true chromatic run of notes, from this low E, upwards, to the usual top notes of the
trumpet.
I am aware that abortive attempts have been made, to perfect the slide trumpet,
even to the trial of a double slide, but hitherto without success.
This double slide is returned to its normal position, by the usual means, viz. an
indiarubber spring.
but
The instrument as shown at Fig. 1, is built in the generally adopted key of F,
I do not bind myself to this key only, or any others, with the usual crooks viz. E, ED,
D, DD and C.
My improvements to facilitate tuning, relate to a construction of crooks, with two
sliding limbs to each crook, instead of being made in one stiff and rigid piece,
as hitherto. In fact I apply an old principle in a new way, viz. almost all brass
musical instruments, have a tuning slide, on some part of the instrument, but none to
the best of my belief, have a tuning slide, on the crooks, I therefor consider, that by
applying this principle, to the crooks of the trumpet, to obtain a very considerable

page_text: advantage, over the old method of tuning, viz. by putting in short bits, next the
mouthpiece. I lay no claim to the principle, but claim the application only, of the
tuning slide to the crooks.
Fig. 2 is a drawing of the C crook, ordinary system, viz. all stiff and rigid.
Fig. 2 is the C crook made as adopted by me, with two moveable limbs, of which
X and X are the new inner tubes, 3" long, and X and X are the two new outer
tubes, of a corresponding length. Thus by pulling out the sliding end A A.
the instrument can be tuned, to the desired pitch, to a shade, without the defects,
caused by tuning with bits as hitherto. Moreover the construction of a trumpet as
herein set forth, prohibits me from putting a tuning slide, to the body of the
instrument, lience the application of the tuning slide to the crooks.

Fig. 4 old D crook.
Fig. 4 new D crook with 1" slide.
The same principle is applied to the B and the B crooks. A drawing is 1 think
unnecessary for these crooks, as they are made the usual length, to put them in their
proper keys. The preceding remarks on the C crook, to be read as applied to these,
and also the letiers and figures used therein.
The E, E and F crooks are made as hitherto, and tuned as hitherto, as their shape
prohibits me from improvements in their construction.
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) Constructing a trumpet, with a double tube slide, having 4 sliding limbs, as
and for the purpose berein set forth.
(2) Constructing trumpet crooks with tuning slides as and for the purpose herein
described, the whole substantially as described and shown.
