Description
y 9 5. c. P. CAULKINS 2,375,893
PROJECTILE Filed April 24, 1941 INVENTOR (68:22 E (az/Z'i'z ns I ATTORNE Patented May 15, 1945 UNITED STATES PATENT OFFICE PROJECTILE Cecil P. Caulkins, New London, Conn.
Application April 24, 1941, Serial No. 390,084
2 Claims.
This invention relates to improvements in projectiles, and its object is to provide a projectile of the type which has an arbor which fits into the barrel of the gun from which it is shot.
This invention is applicable to the type of projectile which has a stem or arbor which fits into the barrel from which it is shot, or to such devices in which the projected explosive charge is afiixed to a carrier having such an arbor, and its object is to provide an arrangement for utilizing the interior of the arbor to enlarge the capacity of the explosive chamber of the gun and to attain further advantages which will be described hereinafter. I will describe my invention as applied to such a projectile as that shown in United States Patent No. 1,539,027, issued to Andrew J. Stone, May 26, 1925, in connection with what is commonly known as a Y gun, but obviously it is not limited to the specific form of'projectile shown therein or to use with that specific form of gun.
Referring to the drawing in which an embodiment of the invention is shown in sectional elevation, l designates a casing which forms an explosion chamber. H is a pedestal upon which the casing I0 is mounted and I2, I 2 designate two barrels projecting from the casing and welded thereto at l3. The inner surfaces of these barrels are smooth. 7
The projectile comprises a hollow cylindrical arbor '30 closed at its outer end by a head 3| to which is secured a bomb or depth charge 32, Its inner end is closed except for an orifice 33 by a transverse head 34.
When gas is injected into the explosion chamber under high pressure, as by the firing of a v cartridge, the projectile is shot out of the barrel.
If the carrier end of the arbor is closed, according to former practice, there is an excessive muzzle blast due to the comparatively large caliher and short barrel of guns of this character.
This results in the waste of a considerable volume of the powder gas and, furthermore, discloses the position of the gun to the enemy.
By providing the orifice 33, the volume of the space within the arbor is added to the volume of the explosion chamber. Upon firing the gas of combustion and some partly unconsumed particles of powder will be forced into the interior and this gas will act as a propelling jet after the arbor has left the muzzle of the gun. The volume of the space may be lessened if desired, for example, by extending the central part of the head 31' inwardly, as indicated by the dotted line 31A.
, This invention is not limited for use with the particular form of gun shown, and modifications may be made within the spirit and scope of this disclosure. I intend no limitations other than those imposed by the appended claims.
What I claim is:
l. A projectile having a hollow arbor adapted to fit into the barrel of a gun having an explosive chamber and to enlarge the capacity of said chamber, said arbor being closed at its outer end and arranged to carry a depth charge and having a permanent transverse member near its other end constructed with an. orifice for admitting gases from an explosive charge in the explosion chamber of the gun into the arbor and to restrict the escape of said gases from the arbor.
2. A projectile having a hollow arbor adapted to fit into the barrel of a gun having an explosion chamber and to enlarge the capacity of said chamber, said arbor being closed at its outer end CECIL P. CAULKINS.
