Abstract
Abstract Apparatus for piercing the earlobe to produce an opening for the wearing of earrings. A relatively movable anvil and carriage are provided. The carriage mounts a precompressed spring, bearing against a piercing dart. A spring housing and barrel on the carriage are also relatively movable. The earlobe is placed between the anvil and carriage and the carriage moved into engagement with the earlobe. Further pressure on the carriage produces relative movement between the spring housing and barrel and this relative movement causes dual triggers to be cammed out of engagement with the piercing dart. The movement of the triggers releases the dart which pierces the earlobe and is guided into a catch button on the anvil. A catch spring engages the shaft of the piercing dart and holds the parts in association so that the body portion of the apparatus may be removed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
An apparatus for piercing of an earlobe to create and sustain an opening for the attachment of earrings, including a spring propelled piercing dart, and wherein the improvement comprises: an anvil means, carriage means mounted on said anvil means for guided movement of carriage means toward said anvil means, a piercing dart positioned on said carriage means, spring means retained on said carriage means positioned against said piercing dart and having a resilient bias for driving said piercing dart through an ear lobe and into said anvil means, said piercing dart having a piercing shaft, the axis of said piercing shaft intersecting said anvil means, and latch means including a trigger means responsive to engagement pressure of said carriage means against an ear lobe for releasing said piercing dart from said carriage means.
Claim 2
Independent Claim
133 words
An apparatus for piercing of an earlobe to create and sustain an opening for the attachment of earrings, including a spring propelled piercing dart, and wherein the improvement comprises: an anvil means, carriage means mounted on said anvil means for guided movement of carriage means toward said anvil means, a piercing dart positioned on said carriage means, spring means retained on said carriage means positioned against said piercing dart and having a resilient bias for driving said piercing dart through an ear lobe and into said anvil means, said piercing dart having a piercing shaft, the axis of said piercing shaft intersecting said anvil means, and latch means including a trigger means responsive to engagement pressure of said carriage means against an ear lobe for releasing said piercing dart from said carriage means.
Claim 3
Dependent Claim
48 words
The earlobe piercing apparatus of claim 1 wherein: said dart has a body portion, said carriage means including a barrel in axial alignment with said dart and interposed between said dart and said anvil means, said dart having a body portion sized to be received through said barrel.
Claim 4
Dependent Claim
27 words
The earlobe piercing apparatus of claim 2 wherein: said shaft of said dart receives a guide button, said guide button has a sliding fit in said barrel.
Claim 5
Dependent Claim
42 words
The earlobe piercing apparatus of claim 1 wherein: said anvil means includes a catch button, said catch button having a bore in alignment with the axis of said piercing shaft, and catch means on said catch button for retaining said piercing shaft.
Claim 6
Dependent Claim
29 words
The earlobe piercing apparatus of claim 4 wherein: said catch means comprises a catch spring with a piercing shaft receiving bore sized to engage and hold said piercing shaft.
Claim 7
Dependent Claim
22 words
The earlobe piercing apparatus of claim 5 wherein: said piercing shaft includes a plurality of grooves disposed to engage said catch spring.
Claim 8
Dependent Claim
62 words
The earlobe piercing apparatus of claim 1 wherein: said trigger means comprises a trigger member mounted for movement with a first part of said carriage means and engaging a ramp on a second part of said carriage means wherein relative movement of said first and said second parts of said carriage means cams said trigger member out of engagement with said dart.
Claim 9
Dependent Claim
19 words
The earlobe piercing apparatus of claim 7 wherein: said trigger member is permanently deformed by movement over said ramp.
Claim 10
Dependent Claim
26 words
The earlobe piercing apparatus of claim 1, wherein: said guide means restrains said carriage means to lineal movement parallel to said axis of said piercing shaft.
