Abstract
Abstract A solid horn for sonic or ultrasonic energy transfer is provided with a sleeve assembly adapted to engage the workpiece to which the horn transfers energy. The sleeve assembly limits the penetration of the horn tip into the workpiece.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
215 words
A sonic tool comprising: a solid horn adapted to oscillate at a sonic frequency when receiving sonic energy at an input surface and having an opposite output surface disposed substantially at an antinodal region of said horn and adapted to be in contact with a workpiece for transferring sonic energy thereto, a first annular sleeve mounted to said horn and substantially vibration isolated therefrom; a second annular sleeve movable axially relative to said first sleeve and surrounding at least a portion of said horn in proximity to said output surface of said horn, and said second sleeve having a workpiece engaging surface adapted to engage an exposed surface of the workpiece to which the output surface of said horn is adapted to transfer such energy; resilient means disposed between said first and second sleeves for urging said second sleeve in axial direction of said horn toward engagement with such workpiece, and responsive to the penetration of the output surface of said horn into the workpiece said second sleeve being urged in said axial direction relative to said first sleeve against the force exerted by said resilient means, and means for limiting the axial motion of said second sleeve relative to said first sleeve, whereby to limit the penetration of said output surface into the workpiece.
Claim 2
Dependent Claim
177 words
A sonic tool comprising: a solid horn adapted to resonate when receiving sonic energy at an input surface and transfer such energy to a workpiece by means of an opposite output surface, said output surface being shaped to penetrate into the workpiece; a pair of telescoping sleeves disposed about said horn; means for mounting a first one of said sleeves with one of its ends at a nodal region of said horn; resilient means disposed between said sleeves for urging the second one of said sleeves in extended position for causing the distal end of said second sleeve to be disposed for engaging the workpiece during the process said output surface is in energy transferring relationship with the workpiece and urged into the workpiece, and means for adjustably limiting the amount of retraction of said second sleeve in response to the said second sleeve being urged against the force exerted by said resilient means, whereby to limit the penetration of said output surface in the workpiece when said output surface is in forced contact with the workpiece.
Claim 3
Dependent Claim
46 words
A sonic tool as set forth in claim 3, said means for limiting including adjustable means coacting between said first and second sleeves for setting the distance said second sleeve is adapted to retract into said first sleeve against the force exerted by said resilient means.
Claim 4
Dependent Claim
16 words
A sonic tool as set forth in claim 3, said means for mounting including resilient means.
Claim 5
Dependent Claim
17 words
A sonic tool as set forth in claim 3, said resilient means including a helical coil spring.
Claim 6
Dependent Claim
24 words
A sonic tool as set forth in claim 3, the output surface of said horn being pointed to facilitate penetration thereof into the workpiece.
Claim 7
Dependent Claim
198 words
A tool comprising: a solid horn adapted to oscillate at an ultrasonic frequency along its longitudinal axis when receiving ultrasonic energy at a radial input surface and having an opposite output surface disposed substantially at an antinodal region of said horn, said output surface being adapted to be in contact with a workpiece for transferring ultrasonic vibrations thereto; a first sleevelike member mounted to said horn in substantially fixed position along the longitudinal axis of said horn and in substantially vibration isolated relation; a second sleevelike member disposed slidably movable in axial direction about said first sleevelike member and surrounding at least a portion of said horn in proximity to said output surface of said horn, and said second member having a radially disposed workpiece engaging surface adapted to engage the exposed surface of the workpiece to which the output surface of said horn is adapted to transfer such vibrations, and means for limiting the axial motion of said second member relative to said first member, whereby to limit, when said horn is urged into said workpiece and said workpiece engaging surface engages the exposed surface of the workpiece, the penetration of said output surface into the workpiece.
