[0002] 1. Field of the Invention

[0003] The present invention relates to a screw-in adjustable shotgun choke and more particularly pertains to a new adjustable shotgun choke device for allowing the user to change the choke constrictions without unscrewing one choke and screwing another choke into the barrel of the shotgun.

[0004] 2. Description of the Prior Art

[0005] The use of a screw-in adjustable shotgun choke is known in the prior art. More specifically, a screw-in adjustable shotgun choke heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

[0006] Known prior art includes U.S. Pat. No. 4,713,904; U.S. Pat. No. 2,134,238; U.S. Pat. No. 4,058,925; U.S. Pat. No. 2,153,246; U.S. Pat. No. Des. 158,792; and U.S. Pat. No. 2,092,649.

[0007] While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new adjustable shotgun choke device. The inventive device includes a tubular member having open ends and a bore extending therethrough with the tubular member being adapted to be threaded in a barrel of a shotgun; and also includes a sleeve member having a first end, a second end, and a bore extending therethrough with the sleeve member being removably attached to the tubular member.

[0008] In these respects, the adjustable shotgun choke device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of allowing the user to change the choke constrictions without unscrewing one choke and screwing another choke into the barrel of the shotgun.

[0009] In view of the foregoing disadvantages inherent in the known types of screw-in adjustable shotgun choke now present in the prior art, the present invention provides a new adjustable shotgun choke device construction wherein the same can be utilized for allowing the user to change the choke constrictions without unscrewing one choke and screwing another choke into the barrel of the shotgun.

[0010] The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new adjustable shotgun choke device which has many of the advantages of the screw-in adjustable shotgun choke mentioned heretofore and many novel features that result in a new adjustable shotgun choke device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art screw-in adjustable shotgun choke, either alone or in any combination thereof.
