Article for injecting air into live bait

Claim 2

In a device for injecting a fluid or the like into live bait, the combination comprising: a body member having a cavity formed therein; a barrel member supported partially within said cavity and having an opening extending therethrough; plunger means within said cavity in sliding engagement within one end of said opening; hypodermic needle means within said opening adjacent the other end of said barrel, said hypodermic needle means including a hypodermic needle centrally disposed with respect to said opening and recessed within said barrel; and means for actuating said plunger member to force fluid from within said barrel member.

Claim 3

The combination according to claim 1 wherein said plunger member includes check valve means for permitting fluid to be drawn into said barrel member through said hypodermic needle.

Claim 4

The combination according to claim 2 wherein said actuating means includes spring means for biasing said plunger member away from said hypodermic needle means and trigger means for actuating said plunger means against the force of said spring means.

Claim 5

The combination according to claim 3 wherein said hypodermic needle means includes other check valve means, said check valve means and said other check valve means enabling repetitive injections of air into said live bait without withdrawing said hypodermic needle.

Claim 6

In a device for injecting fluid or the like into live bait, the combination comprising: a body member configured in the form of a handgun and having a component receiving cavity formed therein; trigger means pivotally coupled to said body member at least partially within said cavity; a transparent tubular barrel member within said cavity and having one end extending partly out of said body member; a plug member sealingly engaging the opening of said one end of siad barrel member, said plug member having a hypodermic needle extending therethrough with the top of said needle recessed from said one end of said barrel opening; spring-biased plunger means within the opening of the other end of said barrel member, said plunger means having a cap portion engaging said trigger member for slidable movement within said barrel member in response to pivoting of said trigger member; and check valve means within said cap portion for permitting the drawing of fluid into said barrel member and the forcing of fluid out of said barrel member through said hypodermic needle.

Claim 7

In a device for injecting fluid or the like into live bait, the combination comprising: a body member configured in the form of a handgun and having a component receiving cavity formed therein; trigger means pivotally coupled to said body member at least partially within said cavity; a transparent tubular barrel member within said cavity and having one end extending partly out of said body member; a plug member sealingly engaging the opening of said one end of siad barrel member, said plug member having a hypodermic needle extending therethrough with the top of said needle recessed from said one end of said barrel opening; spring-biased plunger means within the opening of the other end of said barrel member, said plunger means having a cap portion engaging said trigger member for slidable movement within said barrel member in response to pivoting of said trigger member; and check valve means within said cap portion for permitting the drawing of fluid into said barrel member and the forcing of fluid out of said barrel member through said hypodermic needle.

Claim 8

The combination according to claim 5 wherein plug member includes a spring-loaded check valve in fluid communication with said barrel and said needle, said spring-loaded check valve opening in response to fluid urging thereagainst.
