Abstract
An automatic balling gun includes an elongated member having a tubular profile which is easily operated and manipulated by the single hand of the user. A release assembly is mounted along the length of the tubular member to dispense medicine orally to an animal by merely depressing a plunger. A knob is provided on a proximal end of the automatic balling gun which facilitates cocking the gun and loading a dispensing chamber thereof with a capsule or pill to be dispensed. The automatic balling gun can then be inserted into the animal to be treated followed by depressing the plunger on the release assembly to dispense the medication from the gun.
Claims15
An automatic balling gun for dispensing medicine orally to an animal comprising:
- a) an elongated hollow member having a distal and a proximal end and an enlarged diameter portion extending from the distal end of said elongated hollow member and terminating at a stop;
- b) a rod extending along an axis of said elongated hollow member, said rod having a reduced diameter portion, a cap at one end thereof and a knob at the other end, and a spring surrounding said rod and disposed between said stop and said cap to spring bias said cap and rod towards said distal end when said release assembly releases said reduced diameter portion of said rod;
- and
- c) a release assembly, a first portion thereof mounted within said elongated hollow member with a second portion extending through a sidewall of said elongated hollow member and spaced between said distal and proximal ends,
- d) wherein said release assembly holds said reduced diameter portion of said rod in a cocked position and releases said portion from said cocked position to dispense said medicine by said spring bias.

- a) an elongated hollow member having a distal and a proximal end;
- and
- b) a rod extending along an axis of said elongated hollow member, said rod having a reduced diameter portion, a cap at one end thereof and a knob at the other end, said rod being biased by a spring toward said distal end to dispense said medicine;
- and
- c) a release assembly, a portion thereof mounted within said elongated hollow member and spaced between said distal and proximal ends,
- d) wherein said release assembly holds a said portion of said rod in a cocked position and releases said portion from said cocked position to dispense said medicine by said spring bias, said release assembly further comprising:
- i) a sleeve having an open top, closed bottom and a pair of aligned apertures in a sidewall thereof, said sleeve mounted within said elongated hollow member;
- ii) a cylindrical plunger having a first portion sized to engage said sleeve, said first portion having a bore therethrough, and a recess at a free end thereof, and a second portion opposite said free end and sized to seat against said open top of said sleeve;
- and
- iii) a second spring arranged in said sleeve for engagement with said recess to spring bias said plunger upwardly with respect to said sleeve bottom;
- iv) wherein depression of said plunger aligns said apertures and said bore to release said portion of said rod from said cocked position.
