COMPLETE SPECIFICATION.
Improvements in Gongs and in the Manufacture of the Same.
I, EDMUND TOWNSHEND, of the Firm of Townshend's Art Metal Co., Limited,
of Ernest Street, Birmingham, in the County of Warwick, Art Metal Workers,
do hereby declare the nature of my said 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 has for its object improvements in gongs and in the manu-
facture of the same by which I obtain a better result as regards quality and volume,
of sound and also effect a saving in the workmanship. Besides these advantages
I am able by my present invention to make my gongs of a more artistic shape
my present invention being an improvement upon and a development of my
former Patent No. 5160 A.D. 1890.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto five double sized sheets of draw-
inga upon which I have illustrated sufficient examples of my invention to enable
others to apply the invention to any cases occurring in practice.
Figure 1 is an elevation of a gong made according to my invention with the
flange a extending all round but not along the base.
Figure 2 is an inverted cross sectional view of Figure 1 taken on the line 1-2.
Figure 3 is a somewhat similar gong to Figure 1 but the flange a³ extends
around a portion only of the upper portion of the gong.
Figure 4 is an inverted cross sectional view of Figure 3 taken on the line 3-4.
Figure 5 is an elevation of a gong B with the flange 6 extending partially.
around. The lower portion or apron 6 being curled under in an opposite direc-
tion to the flange.
Figure 6 is a side elevation of Figure 5.
Figure 7 is an elevation of a polygonal gong D having a number of curled over
flanges d¹.
Figure 8 is an inverted cross sectional view of Figure 7 taken on the line 5-6.
Figure 9 is a somewhat similar gong to Figure 8 shewing straight flanges d
Figure 10 is an inverted cross sectional view of Figure 9 taken on the line 7-8.
Figure 11 is an elevation of an octagonal goug E having a number of flanges el
curled over in one direction and a number of flanges e curled over the opposite
direction.
Figure 12 is an inverted cross sectional view of Figure 11 taken on the
line 9-10.
Figure 13 is a similar view to Figure 11 having the flanges e bent straight in
one direction and the flanges e bent straight in the opposite direction.
Figure 14 is an inverted cross sectional view of Figure 13 taken on the line
11-12.
Figure 15 is an elevation of a septangular gong F having three ourled over
flanges f
Figure 16 is a cross sectional view of Figure 15 taken on the line 13-14.
