<p>A dispensing device for applying two-part ear tags to animals comprises a housing (20) having a handle (21), there being inserted in a storage chamber (22) of the housing a removable cartridge containing two spaced rows of tag parts (10, 17) which are fed by a spring device (39) to an operating location (24). Squeezing a lever (29) upwardly into the handle (21) drives a plunger (25) downwardly into the operating location (24) so as to disengage an upper tag part (10) from its position in the cartridge and drive it through the animal's ear and into engagement with the corresponding lower tag part (17) in the cartridge, so that the two-part tag becomes affixed to the animal's ear. The transmission between the lever (29) and the plunger (25) comprises a pinion device (28, 28a) which is rotatably mounted on the body of the device and meshes with toothed racks on the lever (29) and plunger (25) respectively.</p> |
