Claim 9

Apparatus as recited in claim 1, in which said means include a carrier structure mounted for movement essentially along said axis, a shaft extending essentially along said axis and mounted to said carrier structure for movement along said axis toward and away from said work piece and relative to said cutter structure, said shaft having an end engageable with the cutter structure to apply axial hammer blows thereto, said shaft having an enlargement centered essentially about said axis and engageable with said wheel and a relation intermittently displacing said shaft in a first axial direction in reponse to rotation of the wheel, and said means including a spring disposed about said shaft and acting thereagainst to yieldingly urge it in the opposite axial direction.

Claim 10

Apparatus as recited in claim 8, in which said wheel is mounted rotatably about a portion of said shaft.

Claim 11

Apparatus as recited in claim 1, including a carrier structure to which said wheel is mounted rotatably, guide means mounting said carrier structure for movement essentially along said axis, and a powered rack and pinion drive for moving said carrier structure along said axis.

Claim 12

Apparatus as recited in claim 1, in which said means include a hammer element for intermittently applying force axially to said cutter structure, said wheel being mounted rotatively about said hammer element.

Claim 13

Apparatus as Recited in claim 1, including a carrier structure to which said wheel is mounted rotatively to turn about said axis, a hammer element mounted to said carrier structure for movement relative thereto in response to rotation of said wheel, guide means mounting said carrier structure for movement along said axis, a swinging arm power oscillated about a second axis in timed relation to the rotation of said wheel about said first mentioned axis, gear teeth on said swinging arm, and a rack engaged by said gear teeth to move said carrier structure in opposite directions along said axis in response to swinging movement of said arm.

Claim 14

Apparatus as recited in claim 1, in which said means include a carrier structure to which said wheel is mounted rotatively and having two arms spaced axially apart, means for actuating said carrier structure along said axis, a hammer shaft mounted by said two arms of said carrier structure for movement along said axis and having an end portion adapted to intermittently strike said cutter structure, an enlargement on said shaft between said two arms engaging the carrier structure in a relation preventing rotation of the shaft, a spring about said shaft acting against said enlargement to urge the shaft in a first axial direction, and a series of teeth carried by the shaft about said axis engageable by corresponding teeth on said wheel to displace the shaft in the opposite direction in response to rotation of the wheel, said wheel being mounted rotatably about said shaft and having a portion journaled within one of said arms of the carrier structure.

Claim 15

Apparatus as recited in claim 13, including means for orbitally oscillating said cutter structure relative to the work piece and relative to said carrier structure and transversely of said axis.

Claim 16

Apparatus as recited in claim 1, including additional actuating means for moving said cutter structure and said work holder and carried work piece relative to one another generally transversely of said axis during said vibratory movement, and in addition thereto, to enhance the cutting action.

Claim 17

Apparatus as recited in claim 1, including additional actuating means operable to shift the cutter structure and work holder and carried work piece relative to one another in an orbital path during said vibratory movement and in addition thereto.

Claim 18

Apparatus as recited in claim 1, in which said means include a hammer element operable in response to rotation of said wheel to apply intermittent axial blows to said cutter structure, said apparatus including additional actuating means for shifting said cutter structure in an orbital path relative to both the work piece and said hammer element and essentially transversely of said axis.
