Improvements in the Construction of Whistles.
I, JOSEPH HUDSON trading as J. Hudson and Co. of the Metropolitan Whistle
Works, 11 & 13 Barr Street Birmingham, Whistle 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:—
This invention relates to the manner in which I construct whistles, whereby I am
enabled to dispense with some of the operations at present necessary when
manufacturing the metal whistles which are now in existence.
In carrying my invention into effect, I construct a metal whistle having only
three seperate parts or pieces to form the complete whistle; and I produce these
seperate parts by ordinary mechanical operations of stamping piercing, and pressing
sheet metal as hereinafter, set forth and as illustrated in the accompanying sheet of
explanatory drawings.
+
1 pierce or cut the blank A from a sheet of metal or other suitable material,
forming the two side ears A1 A2 thereon for the purpose of bending over together
with a portion of the surface A into the shape shown in Fig. 2 and Fig. 3; the
operation of cutting pressing and bending being performed in any ordinary manner
at present in use for similar stamping and piercing operations.
With the blank AI form the top and two sides of my improved whistle, and
with the blank B I form the end and bottom of my whistle as shown in Figs. 4, 5
and 6.
I produce a third metal blank C from sheet metal, and prefer to arrange two lips
or stops C¹ to serve as gauge projections when placing this funnel plate or inner
plate C C C within the case A B of my whistle as shown in sectional elevation in
Fig. 11. These projecting stops C₁ I remove by fileing or grinding when the
whistle is finished as at Fig. 10 and Fig. 12.
I secure the three pieces A, B, C together at their jointing edges by soldering
or brazing, and I cause the funnel plate or inner plate C to be placed in correct
position within the box or case formed by placing A and B together as shown at
Fig. 11, by providing the tail C2 upon the top portion C so that it may rest upon
the inner part of the case B.
I attach any fancy knob or handle D to the end of my case B or to any other
portion of my whistle as may be desired, in the usual ordinary manner.
I sometimes arrange the mouthpieces of my improved whistles with beaded edges
or with surfaces recessed for the reception of small portions of bone, ivory, or other
similar material, when it is desired to increase the comfort of the person in using
such whistles.
And I place peas or like articles within the hollow case when constructing my
whistles for producing certain tones and effects.
I do not limit the application of my improved method of constructing metal
whistles, to whistles having the precise shape and configuration shown in the
accompanying drawings but I modify the extent of the depression forming the
drum or hollow case, also the length and breadth of the mouth piece to suit any
particular requirement, without departing from the essential feature of my inven-
tion as herein set forth when constructing whistles of the shape and configuration
set forth in the accompanying drawings.
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 construction and arrangement of metal whistles from three separate main

page_text: pieces or portions of sheet metal, substantially as and for the purposes herein before
described.
2. In a metal whistle the application of a stop or lip projection or projections
such as C' upon the funnel plate substantially as and for the purpose herein
before set forth and as illustrated in Figs. 7, 8, 9, and 11 of the accompanying
drawings.
3. The construction of metal whistles having their cases in part formed with the
sides and upper portions of the mouth pieces as one piece or one fitting, sub-
stantially as hereinbefore described and as illustrated in Figs. 1, 2 and 3 of the
accompanying drawings.
4. The construction of metal whistles having their cases in part formed with the
cover, end or back, and the under portion of the mouth piece, as one piece or
fitting; substantially as herein before described and as illustrated in Fig. 4, 5,
and 6 of the accompanying drawings.
Dated this 16th day of November 1891.
