Grooves of Shot or Shell and in Windage Rings for the samé.
I GEORGE BAILEY of 55 Gray Street, Blackfriars Road, Surrey, Engineer, do
bereby declare the nature of this invention to be as follows:—
The object of this invention is to make the windage grooves of shot or shell of
wavy-serrated or other irregular shape for the reception of windage rings of
corresponding shape or of other shape which can be inserted, forced, or pressed
into to fill or partly fill said grooves, a portion of said ring projecting beyond the
diameter of the shot or shell and in some cases with a projecting lip or bead
pressing on the body of the shot or shell.
The wavy, serrated or other irregular surface or surfaces of the grooves may be
produced by casting, tooling or otherwise.
The rings may be of corresponding shape to that of the grooves or of any other
suitable shape to engage in or be pressed, or be otherwise inserted into said
grooves or plain rings. may be forced into the irregularly shaped grooves of the
shot or shell and be made to conform to the contour of said grooves by pressure,
with or without a portion overlapping the body of the shot or shell. The wavy,
serrated or other irregularly shaped rings may be of copper, soft metal, or other
suitable material or wire wound into shape corresponding to that of the groove or
grooves or of plain shape to be forced into said irregularly shaped grooves; the
purpose being to ensure a complete holding of the ring from several points in the
diameter of the shot or shell with less liability to fracture or partaking of an
unequal expansion under the action of the gases at the time of firing.

Agent for the said G. Bailey.

I, GEORGE BAILEY of 55 Gray Street, Blackfriars Road, Surrey, Engineer, 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 object of this invention, which is represented on the annexed drawings, is
to make the windage grooves of shot or shell of wavy serrated, or other irregular
shape for the reception of windage rings A of corresponding shape, or of other
shape which can be inserted, forced, or pressed into to fill or partly fill said
grooves. A portion of said ring A projects beyond the diameter of the shot or
shell B as shown in Figures 1 and 2, and in some cases with a projecting lip, or
bead C, shown at Figure 3, pressing on the body of the shot or shell. Figure 4
represents a modified arrangement of irregular wavy rings, and Figures 5 and 6
are perspective views of such rings. The wavy, serrated, or other irregular surface
or surfaces of the grooves may be produced by casting, tooling, or otherwise.
Figures 7 and 9 show the groove D, only one surface of which is irregular,
The rings A may be of corresponding shape to that of the grooves, or of any
other suitable shape to engage in, or be pressed, or be otherwise inserted into said
grooves, or plain rings may be forced into the irregularly shaped grooves of the
shot or shell, and be made to conform to the contour of said grooves by pressure,
with or without a portion overlapping the body of the shot or shell. The wavy,
serrated, or other irregularly shaped rings, may be of copper, soft metal, or other
suitable material, or wire wound into shape corresponding to that of the groove, or
grooves, or of plain shape, to be forced into said irregularly shaped grooves, as
shown at Figure 8, the purpose being to ensure a complete holding of the ring
from several points in the diameter of the shot or shell with less liability to
fracture, or partaking of slipping motion, or of an unequal expansion under the
action of the gases at the time of firing.
The shot or shell may have several windage grooves of the same, or of different
shape, or rings of similar, or different shapes (if desired) as shown at Figure 10,
wherein are two rings, plain on one side and toothed on the other side, at the
back, and one ring plain on one side and pointed at the other, at the front portion
of the shell B.
Figures 11 and 12 show modified forms of ring and groove, and Figures 13
and 14 are perspective views of rings having projecting lips, or beads C, C.
Figure 15 is a section of a shell having a windage groove I wavy at the bottom
with certain parts E, E, deeper than other parts F, F. Figures 16 and 17 are
modifications in which the rings A, A, do not entirely fill the grooves D, D.
The advantage of this arrangement is, that on the gun being fired, the gases
from the charge exert force against the ring A which finds a bearing for itself

page_text: without causing it to leave the groove. Said ring is preferably made of copper or
other soft metal.
The groove D may be undercut as at Figure 16.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is:-
1. Manufacturing shot or shell with wavy, or irregular shaped annular grooves
for the reception of rings which already possess a corresponding shape, or can be
made to conform to the shape of the groove, or to such a shape as to fix them in
position within the annular groove, upon the base of said groove, or against the
wall or walls of said groove, as described and shown on the annexed drawings..
2. Manufacturing and employing irregularly shaped rings single or compound,
as windage rings, to fit, or be fixed on the exterior of shot or shell preferably
grooved for the reception of said rings, all according to the shape shown on the
annexed drawings, or any modification thereof.
