Benefits of technology

The present invention is a device for propelling a projectile through the air. It includes a tubular shaped component with a lumen and an open end and a closed end. A second component is engaged with the first component to create a gas-filled compression chamber. The assembly allows for a substantially free axial movement of the second component back and forth in the compression chamber. The device also includes a payload, such as an arrow or a bolt, that can be selectively mounted on the assembly. A man-powered launcher is used to generate the driving force to propel the projectile from the launcher. The device also includes a friction collar to retard movement of the cartridge and a slide ring assembly to mitigate impact forces at launch. The device also includes a pressure valve to allow the compression chamber to be pressurized before the driving force is applied and a ferrule attachment for easy replacement of a spent cartridge. The technical effects of this device include improved accuracy and efficiency of projectile propulsion.

Problems solved by technology

This causes a resultant increase in the velocity of one component, and a resultant dissipation in the velocity of the other component; a combination of events that separates the payload from the assembly.

Embodiment Construction

[0039]Referring initially to FIG. 1A, a device in accordance with the present invention is shown and is generally designated 10. As shown, the device 10 includes a projectile 12 and a man-powered launcher 14. In the particular case of the device 10 that is shown in FIG. 1A, the launcher 14 is a vertical bow of a type well known in the art. The launcher 14, however, could as well be a crossbow (not shown) or an air gun (not shown), both of which are of types well known in the pertinent art.

[0040]As illustrated sequentially in FIGS. 1A, 1B and 1C, a purpose of the present invention is to use the launcher 14 to propel the projectile 12 along a flight path (dashed line) 16 toward a target 18. In sequence, FIG. 1A shows the launcher 14 in a configuration for firing the projectile 12. FIG. 1B then shows the projectile 12 as it is being released from the launcher 14. And, FIG. 1C shows the projectile 12, and its payload 20 after it has been separated from the projectile 12 in flight, after...

Abstract

A man-powered system for pneumatically launching a pellet cluster includes a cartridge for holding the pellet cluster. A hollow propulsion shaft receives the cartridge for substantially free travel back and forth in the shaft to establish a variable-volume compression chamber in the shaft, between the cartridge and a closed end of the shaft. When a driving force acts to launch the combination of cartridge and shaft, the cartridge moves to compress gas in the compression chamber for a subsequent expansion that will propel the cartridge forward through the shaft. After launch, the compressed gas acts to separate the pellet cluster from the cartridge and to provide a pneumatic assist that increases the velocity of pellets after separation.

Description

[0001]This application is a continuation-in-part of application Ser. No. 13 / 789,514, filed Mar. 7, 2013, which is currently pending. The contents of application Ser. No. 13 / 789,514 are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention pertains generally to man-powered devices for launching pellet clusters. More particularly, the present invention pertains to man-powered launchers that provide a pneumatic assist to pellets as they are being launched. The present invention is particularly, but not exclusively, useful as a man-powered device that provides, in combination, a cartridge for holding a pellet cluster and a propulsion tube for interacting with the cartridge to create compressed gas during a launch, to thereby provide a pneumatic assist for increasing the velocity for the pellets after they become separated from the cartridge.BACKGROUND OF THE INVENTION[0003]An important factor for evaluating the performance of a man-powered launcher is the ve...
