US Patent:

6851692, Feb 8, 2005

Filed:

Feb 18, 2003

Appl. No.:

10/369174

Inventors:

Jeffrey R. Mitchell - Tallahassee FL, US

International Classification:

B60R003/00

US Classification:

280163, 2801642

Abstract:

A step configured to be attached to the drawbar of a trailer hitch. The step incorporates a hole and a ball mount receiver. The ball mount receiver is placed over the ball mount on the hitch. The hole allows the hitch ball and its accompanying lock washer and nut to be used to simultaneously mount the step and the hitch ball. The step is shaped to allow free access to the hitch ball so that a trailer can be attached while the step remains in place. The step then allows a user to step up and over the hitch with attached trailer.

Jeffrey R. Mitchell - Tallahassee FL, US

International Classification:

F41B011/12

US Classification:

124 65, 124 70

Abstract:

An air-powered projectile launcher. A double-acting piston within a pump tube is employed. A separate magazine tube is used to hold a plurality of projectiles. One end of the magazine tube feeds into a barrel assembly. The opposite end is closed by a one-way valve. The muzzle of the barrel is closed by a muzzle valve. When the piston is pulled through a back stroke, an air manifold directs the flow to induce a vacuum in the end of the magazine tube proximate the barrel. The vacuum closes the muzzle valve and opens the one-way valve on the opposite end of the magazine tube. The vacuum then pulls the first projectile into the barrel. When the piston is pushed through a forward stroke, pressure is directed behind the first projectile and in front of the second projectile. The second projectile is forced back into the magazine tube. The pressure within the magazine tube closes the one-way valve, effectively making the second projectile the base of a closed firing chamber.

International Classification:

F41B 1/00
F41B 11/00

US Classification:

124 62, 124 56, 124 63

Abstract:

A blow gun for launching soft projectiles. The blow gun includes an action sleeve which is wrapped around and attached to a receiver. Soft projectiles, such as marshmallows, may be loaded into the breech of the blow gun by rotating the action sleeve approximately a quarter of a turn around the receiver. When rotated in this manner, a loading port in the action sleeve aligns with a corresponding loading port on the receiver, thus exposing the hollow interior of the receiver. A barrel is attached to one end of the receiver so that the hollow interior of the barrel and the hollow interior of the receiver are aligned. A muzzle brake extends beyond the barrel and has a plurality of brake vents to prevent the accidental inhalation of projectiles when inhaling on the muzzle end of the blow gun. The blow gun may be fired by blowing into a blow tube which is fluidly connected with the receiver.

Inventors:

Jeffrey R. Mitchell - Tallahassee FL, US

International Classification:

F41B 11/00

US Classification:

124 65, 124 69

Abstract:

A projectile launcher for launching soft projectiles. The projectile launcher features a breech loading mechanism for loading soft projectiles into the launcher. The projectile launcher includes a pressure vessel which is pressurized by a positive displacement type pump which pumps ambient air into the pressure vessel. The butt stock is integrated to the piston of the pump so that the user may pressurize the pressure vessel by sliding the butt stock back and forth with respect to the pressure vessel. A specialized release valve is provided for optimum release of the pressure charge. Operating pressure for the launcher is limited by the pump design to prevent injury.

International Classification:

F41B 11/18

US Classification:

124 66

Abstract:

A bow-type projectile launcher for launching soft projectiles. The projectile launcher features a pump assembly having a cylinder and piston. The piston is attached to a bow string so that a pressure charge is generated when the user draws and releases the bow string. The pressure charge is released into a chamber which contains a soft projectile. A removable magazine is provided for containing a plurality of soft projectiles. A magazine receiver is provided for attaching the removable magazine to the projectile launcher.

Inventors:

Jeffrey R. Mitchell - Tallahassee FL, US

International Classification:

F41B 11/723
F41B 11/89

Abstract:

A gas valve that can be opened using a trigger mechanism. When triggered, the valve is preferably configured to deliver a rapid release of air and then reset itself in the closed state. Once in the closed state, pressure may again be built on the upstream side of the valve until another release is desired.

Jeffrey R. Mitchell - Tallahassee FL, US

International Classification:

F41B 7/00
F41B 7/08

Abstract:

A toy projectile launching device. The device preferably includes a handle, barrel, muzzle, trigger, cocking shaft, and cocking handle. The device uses a spring loaded shaft in order to launch an orb. In addition, the launching mechanism of the device imparts rotation upon the orb, which stabilizes the orb in flight—thereby achieving an increase in sustained velocity and an increase in the distance traveled.

International Classification:

A63B 37/02

US Classification:

473595

Abstract:

A throwable ball having a large internal passage aligned with its central axis. An insert defines the bounds of the internal passage. This insert is surrounded by compressible foam that gives the ball an easy gripping surface. Interlock features are preferably provided between the insert and the compressible foam so that they do not slip relative to each other.
