Abstract
The invention relates to an applicator for a tag for use on livestock such as cattle, sheep, dogs and the like. The applicator includes at least two pivotally connected handle members which extend into upper and lower jaws. A pin mounting is pivotally connected to the upper jaw member, an elongate pin, to which an ear tag can be attached, being pivotally connected adjacent to one end of the pin mounting. A pin restraining housing is provided adjacent an end of the upper jaw member. The pin mounting normally urges at least part of the pin to be located within the pin restraining housing. The lower jaw member is formed or provided with an actuator such as in the form of a cam surface. On the handles and jaws being closed, the activator comes into contact with the pin mounting, this causing the pin mounting to pivot about its connection to the upper jaw member, allowing the pin to move out of the pin restraining housing. This permits the pin to pivot about and relative to its pivotal attachment to the pin mounting.
