Cattle Slaughter Type Patents (Class 42/1.12)
  • Patent number: 9808193
    Abstract: An apparatus and method for inflicting brain injury on a laboratory animal that employs a platform for supporting the laboratory animal. The platform defines an opening for positioning the head of the laboratory animal over the opening. A projectile is launched from a projectile launching device orientated below the opening of the platform. The projectile launching device has a means for propelling the projectile directly at and/or through the opening of said platform, thereby inflicting brain injury on the animal via either a pressure wave or concussive impact of the projectile. Without helmet, direct impact of the projectile results in severe traumatic brain injury. Use of helmet protects animals from skull fracture, subdural hematoma, intracerebral hemorrhage and contusion yet produces mild concussion-like pathology.

  • Patent number: 9661859
    Abstract: A pneumatic animal stunner employing a stunning rod includes a catch mounted within the housing for alternately holding and releasing the stunning rod. A catch piston is disposed adjacent the catch on a side away from the longitudinal axis, and is in sliding contact adjacent the catch end portion and out of contact with the catch body portion. The catch piston slides between a first position urging the catch end portion toward the stunning rod longitudinal axis in the hold position, thereby holding and preventing the stunning rod from being driven forward, and a second position permitting the catch end portion to move to the release position away from the stunning rod longitudinal axis releasing and permitting the stunning rod to be driven forward. Valves control air flow to cause the catch piston to move between the first and second positions.

  • Patent number: 6250007
    Abstract: A method of providing a new cartridge chamber for the breech of a cattle stunning gun for the purpose of improving the ability of the chamber surface to resist corrosive deformation resulting from firing cartridges in the gun. The method includes machining the breech to remove the original surface and providing an insert sleeve which replaces the machined material with a harder and more resistant material. The disclosure includes the configuration of the insert and its relationship to the machined breech.
