Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
187 words
Apparatus for marking a workpiece comprising: high frequency means for providing displacement at a high frequency, stamp means having a preselected mark formed therein and connected to said high frequency means and engageable with the workpiece for forming said preselected mark onto the workpiece as a result of the high frequency displacement, support means for resiliently supporting the workpiece relative to said stamp means, said support means comprising a support assembly and a securing assembly, said support assembly including a base plate, a support plate having a first outer surface adapted to contact a first surface of the workpiece, and first spring means for resiliently connecting said support plate to said base plate; said securing assembly including a guide plate connected to said high frequency means, an alignment plate having a second outer surface opposing said first outer surface and adapted to contact a second Surface of the workpiece, and second spring means for resiliently connecting said alignment plate to said guide plate; whereby the workpiece is adapted to be compressively retained between said first and second outer surfaces and resiliently aligned relative to said stamp means.
Claim 2
Dependent Claim
187 words
Apparatus for marking a workpiece comprising: high frequency means for providing displacement at a high frequency, stamp means having a preselected mark formed therein and connected to said high frequency means and engageable with the workpiece for forming said preselected mark onto the workpiece as a result of the high frequency displacement, support means for resiliently supporting the workpiece relative to said stamp means, said support means comprising a support assembly and a securing assembly, said support assembly including a base plate, a support plate having a first outer surface adapted to contact a first surface of the workpiece, and first spring means for resiliently connecting said support plate to said base plate; said securing assembly including a guide plate connected to said high frequency means, an alignment plate having a second outer surface opposing said first outer surface and adapted to contact a second Surface of the workpiece, and second spring means for resiliently connecting said alignment plate to said guide plate; whereby the workpiece is adapted to be compressively retained between said first and second outer surfaces and resiliently aligned relative to said stamp means.
Claim 3
Independent Claim
25 words
The apparatus of claim l with said stamp means supported for movement normal to the plane of the surface of the workpiece to be marked.
Claim 4
Independent Claim
28 words
The apparatus of claim l with said stamp means supported for movement in a direction parallel to the plane of the surface of the workpiece to be marked.
Claim 5
Independent Claim
33 words
The apparatus of claim l with said stamp means supported for movement in a direction which is at an angle less than 90*and greater than 0* relative to the surface to be marked.
Claim 6
Independent Claim
31 words
The apparatus of claim l with said stamp means comprising a marking stamp having said preselected mark formed of a hardened material for direct engagement with the surface to be marked.
Claim 7
Independent Claim
47 words
The apparatus of claim l with said stamp means comprising a flexible member having a treated surface adapted to engage the workpiece and a marking stamp having said preselected mark and engageable with the flexible member of forming said preselected mark by means of said treated surface.
Claim 8
Independent Claim
12 words
The apparatus of claim l with said flexible member being a tape.
Claim 9
Independent Claim
16 words
The apparatus of claim l with said high frequency means being operable in the ultrasonic range.
Claim 10
Dependent Claim
45 words
The apparatus of claim 2 further comprising guide means disposed between said guide plate and said alignment plate for selectively aligning said second outer surface relative to the movement of said stamp means, and with said high frequency means being operable in the ultrasonic range.
Claim 11
Dependent Claim
16 words
The apparatus of claim 3 with said high frequency means being operable in the ultrasonic range.
Claim 12
Dependent Claim
44 words
The apparatus of claim 4 further comprising guide means disposed between said guide plate and said alignment plate for selectively aligning said second outer surface relative to the movement of said stamp means, with said high frequency means being operable in the ultrasonic range.
