Application August 5, 1957, Serial No. 676,224
1 Claim. (Cl. 119-29) This invention relates to a novel method of training bird dogs and to a novel shell for use in the practice of the method.
More particularly, it is an aim of the present invention to provide a novel method for use in training bird dogs to prevent dogs from becoming gun shy and at the 1sjame time for training the dogs to retrieve a simulated ird.
A further object of the invention is to provide a shell for use in connection with the novel method which can be fired from a shotgun with the same sound as is produced by the firing of a conventional shotgun shell, and which shell contains a harmless projectile which is propelled from the muzzle of the gun by the firing of the shell and which can be utilized to teach the dog to retrieve.
A further object of the invention is to provide a shell wherein the projectile constitutes a compressed mass which expands after leaving the muzzle of the piece to assume a size nearly equal to the size of a small bird so that it can be as readily retrieved as a bird and which projectile is impregnated with a birds scent.
Still a further object of the invention is to provide a dog training shell wherein the expansible projectile, when expanded, is sufficiently soft and yieldable so that it would cause no injury by striking a dog a short distance from the muzzle of the piece.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a present- 1y preferred embodiment thereof, and wherein:
Figure 1 is an elevational view of the dog traing shell;
Figure 2 is an enlarged longitudinal sectional view thereof, taken substantially along a plane as indicated by the line 22 of Figure 1;
Figure 3 is a cross sectional view of the shell taken substantially along a plane as indicated by the line 3-3 of Figure 2;
Figure 4 is a perspective view, on a reduced scale, showing the projectile as it appears compressed either within the shell or while passing through the gun barrel, and
Figure 5 is a perspective view showing the projectile as it may appear expanded.
Referring more specifically to the drawing, the bird dog training shell in its entirety is designated generally 7 and includes a casing 8 having a metal cap or head 9 at one end thereof in which is provided a primer'10. The inner portion of the case 8, located adjacent the cap or head 9, contains a powder charge 11 forming the propellant charge of the shell 7. The parts previously described constitute conventional parts of a shotgun shell.
In lieu of the shot or pellets which are conventionally mounted in the outer part of a shotgun shell, the outer 2,851,991- Patented Sept. 16, 1958 portion of the chamber of the shell casing 8 contains a projectile 12 constituting a compressed mass of a readily yieldable material such as foam rubber or sponge rubber. A conventional wadding 13 is disposed in the shell casing 8 between the propelling charge 11 and the projectile 12. A wad 1 3 is retained in the outer or forward end of the shell casing 8 by crimping of the forward end of the shell casing as seen at 15. The compressed projectile 12 is held under pressure between the wads 13 and 14 and by the portion of the casing 8 surrounding the projectile.
The projectile 12 is preferably impregnated With a birds scent and is adapted to be fired in the same manner as a conventional shotgun shell from a. shotgun, not shown. The shell 7 is utilized for training a bird dog and when fired by detonation of the primer 10 and powder charge 11, an audible report is produced in the same manner as when firing a conventional shotgun shell. This is utilized to train and familiarize the dog with the sound of a gun being fired so that the dog will not be gun shy. When the powder charge 11 is exploded the projectile 12 is propelled from the shell casing 8 and gun barrel and after passing from the muzzle of the barrel expands from its compressed shape as seen in Figure 4 to its normal expanded size and shape as seen in Figure 5 and wherein the projectile is designated 12a. The projectile 12 can be propelled a considerable distance from the firearm and can be utilized to simulate a bird and to be retrieved by the dog. The dog can be taught to follow the flight of the projectile when propelled from the gun, to then locate the projectile by scent and to retrieve the projectile.
The projectile 12a is shown as being of rectangular shape and substantial thickness in Figure 5. However, said projectile could be of other shapes such as of circular cross section when expanded. The compressible material of which the projectile is formed enables it to be compressed and reshaped so as to fit the outer chamber of the shell case 8 between the wads 13 and 14. The compressed and relative solid condition of the projectile 12 as it is propelled through the gun barrel enables it to be propelled a considerable distance from the muzzle of the gun. The projectile expands after leaving the muzzle of the gun barrel and becomes sufficiently soft and yieldable so that should the projectile accidently strike the dog or a human after having travelled a short distance from the muzzle of the gun, no injury Would result. The projectile will cause no damage to a gun barrel and the shell 7 may be used in any shotgun of a proper gauge to fit the shell without damage to the gun barrel. It will also be apparent that the shell 7 may be made in various sizes to fit shotguns of various gauges.
Various modifications and changes are contemplated and may be resorted to, without departing from the function or scope of the invention as hereinafter defined by the appended claim.
I claim as my invention:
The method of training a retrieving dog which comprises producing an audible explosive report, and incidentally thereto producing for the dog the sensation of sight and smell of a bird or other animal.
