Abstract
An electrical stunning device (10) to stun and immobilize an animal includes a first contact tip (15) and a second contact tip (23) to contact the animal. The first contact tip (15) is operatively connected to a first voltage wire (47) and the second contact tip (23) is operatively connected to a second voltage wire (46). The second contact tip (23) is pivotable to activate a proximity switch (43), which closes the circuit and allows voltage to be applied to the first contact tip (15) via the first voltage wire (47) and the second contact tip (23) via the second voltage wire (46) to stun the animal.
Claims17
A device adapted to be manually placed upon an animal for stunning the animal, comprising:
- a. a first contact tip having a first contact surface, said first contact surface contacting the animal;
- b. a second contact tip having a second contact surface, said second contact tip being pivotable to allow said second contact surface to contact the animal after contact has been established with said first contact surface;
- c. a circuit having a first voltage wire and a second voltage wire, said first voltage wire operatively connected to said first contact tip and said second voltage wire operatively connected to said second contact tip;
- and
- d. a proximity switch proximate said second contact tip and in series with said circuit, said proximity switch being activated when said second contact tip is pivoted and said second contact surface contacts the animal, wherein said proximity switch closes said circuit and allows voltage to be applied to said first contact tip and said second contact tip after said second contact tip has been pivoted and said second contact surface contacts the animal thereby stunning the animal.

A device adapted to be manually placed upon an animal for stunning the animal, comprising:
- a. a switch, said switch having a control wire;
- b. a proximity switch in series with the control wire, said proximity switch sensing when contact has been made with the animal;
- and
- c. a circuit having a first voltage wire operatively connected to a first contact tip and a second voltage wire operatively connected to a second contact tip, said second contact tip being pivotable thereby activating said proximity switch, wherein said proximity switch closes said circuit and allows voltage to be applied to said first contact tip and said second contact tip to stun the animal when contact with the animal has been made with both said first contact tip and said second contact tip thereby sensing when contact has been made with the animal said second contact tip being pivoted to contact the animal after contact has been established with said first contact tip.
1 more element
A method for activating a stunning device when the stunning device is in contact with an animal, the stunning device having a first contact tip and a second contact tip, the first contact tip contacting the animal's neck and the second contact tip being placed proximate the animal's shoulder;
- comprising:
- a. manually pivoting the second contact tip to contact the animal's shoulder after contact has been established with the first contact tip, wherein pivoting the second contact tip activates a proximity switch located proximate the second contact tip thereby closing a circuit and allowing voltage to be applied to the first contact tip and the second contact tip after said second contact tip has been pivoted;
- and
- b. stunning the animal with the first contact tip and the second contact tip.
1 more element
A method for stunning an animal, comprising:
- a. directing the animal in proximity to a manual stunning device adapted to be placed upon the animal, said stunning device including a first contact tip operatively connected to a first voltage wire and a second contact tip operatively connected to a second voltage wire, the first voltage wire and the second voltage wire being part of a circuit;
- b. placing said first contact tip on the animal;
- c. pivoting said second contact tip after contact has been established with said first contact tip thereby placing said second contact tip on the animal and activating a proximity switch to close the circuit and allow voltage to be applied to said first contact tip and said second contact tip after said second contact tip has been pivoted;
- and
- d. stunning the animal with said first contact tip and said second contact tip.

A method for stunning a hog, comprising:
- a. placing a manual stunning device adapted to be placed upon the hog proximate the hog, the stunning device having a first contact tip operatively connected to a first voltage wire and a second contact tip operatively connected to a second voltage wire;
- b. placing the first contact tip to contact the hog's neck;
- c. pivoting the second contact tip to contact the hog's shoulder, wherein the presence of the hog is thereby sensed and the stunning device is activated, contact being established with said first contact tip and said second contact tip at separate times;
- and
- d. applying voltage to the first contact tip and the second contact tip after said second contact tip has been pivoted thereby stunning the hog.
2 more elements
A method for manually stunning an animal, comprising:
- a. placing a first contact tip operatively connected to a first voltage wire on an animal;
- b. placing a second contact tip operatively connected to a second voltage wire on the animal, wherein said second contact tip is pivoted to contact the animal after contact has been established with said first contact tip;
- c. ensuring the first contact tip and the second contact tip are in fall contact with the animal thereby avoiding a hot stun on the animal;
- and
- d. applying voltage to the first voltage wire and the second voltage wire when the first contact tip and the second contact tip are in full contact with the animal thereby stunning the animal.
2 more elements
A device adapted to be manually placed upon an animal for stunning the animal, comprising:
- a. a first contact tip and a second contact tip for contacting the animal, said first contact tip being operatively connected to a first voltage wire, said second contact tip being operatively connected to a second voltage wire and being pivotable to fully contact the animal;
- b. a stem, said stem being operatively connected to said second contact tip, wherein said stem is in a first position before said second contact tip is pivoted and said stem is in a second position after said second contact tip is pivoted to fully contact the animal;
- and
- c. a proximity switch, said proximity switch being activated when said stem is in the second position thereby allowing voltage to be applied to said first contact tip via said first voltage wire and said second contact tip via said second voltage wire when said first contact tip and said second contact tip frilly contact the animal after said second contact tip has been pivoted, said second contact tip being pivoted after contact has been established with said first contact tip.
1 more element
A device adapted to be manually placed upon an animal for stunning the animal, comprising:
- a. a first arm having a first contact tip for contacting the animal;
- b. a second arm secured to said first arm and having a second contact tip for contacting the animal, wherein contact with the animal is made with said first contact tip, rotation of said first arm rotates said second arm, and then said second contact tip is pivoted to contact the animal, said second contact tip being pivotable independently of said first contact tip after contact has been made with said first contact tip;
- and
- c. a proximity switch in series with a first voltage wire and a second voltage wire, said first voltage wire operatively connected to said first contact tip and said second voltage wire operatively connected to said second contact tip, said second contact tip activating said proximity switch when pivoted thereby allowing voltage to be applied to said first contact tip and said second contact tip to stun the animal when contact has been made with both said first contact tip and said second contact tip after said second contact tip has been pivoted.
