Abstract
Abstract An animal ear tag applicator tool which includes spaced apart first and second retention members each of which is adapted to retain an animal ear tag part. The tool has a body to which is pivotally attached a lever. Movement of the lever toward handle of body results in rectilinear movement of the first retention member toward the second retention member. The tool is characterized by a linkage which transforms pivotal movement of the lever into a varying speed rectilinear movement of the first retention member toward the second retention member relative to the movement of the lever itself.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
195 words
An animal ear tag tool for applying an ear tag characterized by comprising a body including a first retention means for a first part of said tag, a second retention means for a second part of said tag, said first retention means including a first portion facing said second retention means and a second portion adjacent to said first portion, a pivoted lever pivotally mounted on said body, around a first pivot mount, means for transferring movement of said lever into movement of said second portion of said first retention means, said means for transferring being pivotal about a second pivot mount, said second pivot mount being movable in response to pivotal movement of said lever, said means for transferring being engaged with said second portion of said first retention means, guiding means comprising a cam surface and a cam follower, one of which is mounted with said means for transferring, and the other of which is fixed on said body, said cam surface having a profile which imparts variable speed motion to said second portion of said first retention means, said variable speed motion decreasing as said first portion approaches said second retention means.
Claim 2
Dependent Claim
195 words
An animal ear tag tool for applying an ear tag characterized by comprising a body including a first retention means for a first part of said tag, a second retention means for a second part of said tag, said first retention means including a first portion facing said second retention means and a second portion adjacent to said first portion, a pivoted lever pivotally mounted on said body, around a first pivot mount, means for transferring movement of said lever into movement of said second portion of said first retention means, said means for transferring being pivotal about a second pivot mount, said second pivot mount being movable in response to pivotal movement of said lever, said means for transferring being engaged with said second portion of said first retention means, guiding means comprising a cam surface and a cam follower, one of which is mounted with said means for transferring, and the other of which is fixed on said body, said cam surface having a profile which imparts variable speed motion to said second portion of said first retention means, said variable speed motion decreasing as said first portion approaches said second retention means.
Claim 3
Dependent Claim
59 words
An applicator tool as claimed in claim 1, characterized in that the means for transferring comprises a link member having a contact surface engaged with a bearing surface disposed on said second portion of said first retention means, said second portion comprising a movable member, said contact surface being located at a point spaced from said second pivot mount.
Claim 4
Dependent Claim
41 words
