page_text: Invention, for, and during the term of years therein mentioned; to have, hold,

granted or mentioned to be granted unto me, the said John Munns, my
executors, administrators, and assigns, for and during and unto the full end
and term of fourteen years from the date of the said Letters Patent next and
immediately ensuing, and fully to be complete and ended, according to the
Statute in such case made and provided; in which said Letters Patent is
contained a proviso, obliging me, the said John Munns, by an instrument in
writing under my hand and seal, to cause a particular description of the nature
of my said Invention, and in what manner the same is to be performed, to be
inrolled in His Majesty's High Court of Chancery within one calendar month
next and immediately after the date of the said Letters Patent, as in and by
the same, relation being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Munns, do hereby declare that my said Invention consists, and is made
and performed, in the following manner, that is to say:-
The trumpet is to be made of copper, brass, tin, or any other metal, com-
position, or material that is capable of being formed into a tube or tubes.
The tube or tubes for this trumpet may be either cylindrical or conical, round
or square, or any other form that be most convenient to be adapted to the
carriage or carriages they may be intended for. The diameter of the tube or
tubes, if cylindrical, may be from four-eighths of an inch to two inches, more
or less, according to the make of the carriage or carriages they are to be put
in; if conical or otherwise, the diameter may be at pleasure. The length of
the tube or tubes may be proportioned according to the length of the carriage
or carriages in which they are to be placed, that is to say, from two feet
six inches to six feet, more or less. This trumpet is to be made in a
variety of forms, and may or may not be divided in compartments, and
contains one or more tubes, joined together by solder, screw, sockets, rivets,
pieces of tubes sliding into one another, or any device that may be formed of
uniting or holding them together. At one end of this trumpet is a mouth-
piece; at the other end may or may not be a drum or sounding piece, similar
to a common trumpet; in the middle, or any part of the tube or tubes of this
trumpet, may be a partition or division, to receive a double-box, barrel, or tubes,
one in another; with a spring upon an arbor, similar to the spring of a clock, or
on sockets or mitres, sliding pieces, or a solid piece with cores or otherwise,
(that are made to move in different forms, either circular, horizontal,
perpendicular, or any other form that movement can be made to answer the
same end), with a strap or holdfast, and a spring affixed thereto, to raise itself

page_text: to its proper place, or to the roof of the carriage, as is most convenient. To
the mouth-piece part of the tube may also be affixed pulleys, or any other
device that will cause an equilibrium, to convey it to its proper place. The
tube from this mouth-piece to the box, barrel, et, ct, is about eighteen
inches long, more or less, and contains a staple and roller to receive the spring,
which carries and-keeps it up, and is affixed to the inside box, or barrel, or
tube, or socket, or mitre, or sliding piece, (all which must be made with a hole
through them for the voice to pass through), or solid piece, with cores, that
will-move according to the form it is made in, and may used as follows:-.
First, when this trumpet, is moved by the hand from the place where it is
affixed to the mouth it will be open, and will convey the voice to the coachman,
footman, or postilion, without stopping or letting down the windows of the
carriage. "

Secondly, the box, or barrel, or tube, or socket, or mitro, or sliding piece
with holes, or solid piece with cores, may or may not be made to answer the
purpose of a valve, so as to stop out or hinder the cold air from coming into
the carriage after it has been spoken through. Upon loosing the hand from
the tube; the spring pulleys, or any equilibrium affixed thereto,, causes it to
return to its former position. To this tube of the mouth-piece to the inside
box, barrel, tube, socket, mitre, sliding and solid piece with cores, is an outer
.box, barrel, tube, socket, mitre, or sliding piece, with two holes, one to receive
the tube from the mouth-piece, the other to affix to the larger end of the
trumpet, which receives- the sounding piece or drum. This trumpet may be
made with two or more mouth-pieces, so as to be convenient to two or more
people that may be in the carriage; by the addition of double boxes, barrels,
tubes one in another, sockets, mitres, sliding or solid pieces with cores, that
are made to move in different forins, as before has been mentioned; as
follows: From the outside box, barrel, tube, socket, mitre, or sliding piece, to
which the drum end of the trumpet is, affixed, must be one tube, of about
twenty. inches long, more or less, or two tubes, about ten inches long, more or
-less. The tube of twenty inches long must have a partition in the middle,
with one hole on each side, to convey the voice. to the drum end of the
trumpet; this partition in the middle of the tube may be performed by an
adjusting screw or running swivel, or otherwise. The two holders and
partitions in this tube must be so contrived to be put in the outer box so that,
when any one speaks through it, to meet the hole of the outer box, whereunto
the tube of the drum end belongs, and to be as air-tight as possible. The two
extreme ends of this tube is affixed to a box and other apparatus, as before

page_text: described, in the tube that leads from the mouth-piece to the double box in
the single trumpet. The two short tubes, of about ten inches long, more or
less, are to have one stop to each of them, and a hole near them, similar to
that of the long one, which ends are to be placed in the outer box, in the same
manner as the long one, herein-before mentioned; these must also be as air-
tight as possible. The extreme ends of those tubs must be placed in the same
'manner as the long one, and that described for the single trumpet. These
tubes of twenty and ten inches may be moved by a slide, or spring, or adjusting
screw, at the extremity of each, so contrived as to move from one side to the
other, the distance of one of the holes, which will enable any one to speak out
of either. This trumpet may also be made with one or two mouth-pieces, and
to answer every purpose of the other by a doublé mitre and tube, proportioned
to the length of the carriage, and affixed with or without the springs and other
apparatus, before mentioned, only taking eare that while one of the mouth-
pieces is used that the air is stopt out from the other by a small plug or valve,
or otherwise; this may be appropriated to the front and back of any carriage,
and by double sockets, screws, and boxes; may be turned to any part of the
carriage. This trumpet may also be so formed with two drum pieces, one
to the coachman, the other to the footman, with a 'box, c, c, c, in the
middle, with a slide or spring, so as to speak to the coachman and footman, at
one and the same time, and from one mouth-piece and hole, as is before
⚫déscribed. This trumpet may also be made in one tube, similar to the
common trumpet, with a spring or rest near the drum end, so as to admit it
to be brought down to the mouth and return again to its place. This is a
particular description of my said Invention, and the manner in which I do
make, perform, or use the same.
In witness whereof, I have hereunto my hand and seal subscribed and
set, this Thirtieth day of October, in the thirty-third year of the reign
of our Sovereign Lord George the Third, by the grace of God, of
