Improvements in Slide Trombones.
1, PETER ROBINSON, trading as Joseph Higham, of 127 Great Ducie Street,
Strangeways, Manchester, in the County of Lancaster, Brass Musical Instrument
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to slide trombones and the object of my invention is to
obtain echo results from such instruments.
•
In applying my improvement to a slide trombone I fit on the slide a valve
attachment to which is connected an echo bell, and between the valve and echo bell
is fitted a tuning slide.
This echo attachment can be instantly applied to or removed from a slide trom-
bone and when in position.does not. interfere with its ordinary tone; when it is
desired to use the echo attachment the valve is opened by the performer and the
air finds its way into the echo bell and thereby an echo result can be obtained.
This attachment is also useful when it is desired to practice the trombone without
creating much sound.

COMPLETE SPECIFICATION.
Improvements in Slide Trombones.
I, PETER ROBINSON, trading as Joseph Higham, of 127 Great Ducie Street,
Strangeways, Manchester, in the County of Lancaster, Brass Musical Instrument
Manufacturer, 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 :-
My invention relates to slide trombones and the object of my invention is to
obtain echo effects from such instruments in addition to the ordinary tone.
In applying my improvement to a slide trombone I fit on the slide a valve
attachment to which is connected an echo bell, and between the valve and echo
bell is fitted a tuning slide.
This echo attachment can be instantly applied to or removed from a slide trom-
bone and when in position does not interfere with its ordinary tone; when it is
desired to use the echo attachment the valve is opened by the performer and the
air finds its way into the echo bell and thereby an echo result can be obtained.
And in order that my invention may be fully understood and readily carried into.
effect I will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side view of a slide trombone fitted with an echo attachment
according to my improvements.
Fig. 2 is a different view of the same instrument shown partly in dotted lines in
order to illustrate the application of the echo attachment more clearly.
Fig. 3 is a detail view of the echo attachment and Fig. 4 is a part of the
same and
Fig. 5 is a detail view of the filling up tube which is substituted for the echo
attachment when the latter is removed.
The slide trombone consists of the following parts substantially of the ordinary
construction namely the mouth piece a, the slide b, the body c, and bell d..

page_text: The echo attachment marked E consists of the following parts: A piston valve
and casing connected by a tube to a tube hha tuning slide i and the echo
bell j.
When the echo attachment E is required its tube is pushed into the body
tube c as shown in Fig. 1 and also in dotted lines Fig. 2 and the slide b is secured
to the tube by the clip and thumb screw 7. When in position the echo attach-
ment does not interfere with the ordinary tone of the instrument but when it is
desired to use the echo attachment the piston valve f is opened by the performer
and the air is thus diverted from the body tube c and bell d and turned into the air
passage leading to the echo bell d whereby a soft or echo effect is obtained.
h
This attachment is also useful when it is desired to practice the trombone
without creating much sound.
When not required the echo attachment can be removed and the filling up tube m
shown in Fig. 3 substituted as a means for connecting the slide directly to the
body c.
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. The combination with a slide trombone, of an attachment whereby an echo or
soft effect can be produced in addition to the ordinary tone of the instrument
substantially as herein set forth.
2. The combination with a slide trombone, of the echo attachment E substantially
as herein shown and described for the purpose specified.
Dated this 9th day of November 1891.
