Ultrasonic device and method

In an ultrasonic device having a casing, an energyzing means adjacent said casing, means for introducing fluid into an end of said casing and an insert assembly insertably mounted in said casing, the improvement in said insert assembly comprising

• a hollow sleeve adapted to be insertably mounted in the end of the casing and in fluid connection therewith, connecting means extending through said hollow sleeve, said connecting means comprising a shank being mounted at a spaced distance from the internal walls of said hollow sleeve to thereby form an annular space between said sleeve and said shank said annular space being in fluid communication with said casing, and an annular nozzle adjacent said hollow sleeve anterior end for fluid to exist therefrom, said connecting means also comprising a ring transversely mounted on said shank at the nodal point thereof, said hollow sleeve having an internally located transverse slot adapted to accomodate said ring, and a flow detour means for conducting fluid around said ring and into said annular space
• ultrasonic vibration means fixedly connected to said connecting means at the posterior end thereof, and adapted to be inserted into said casing into position to be acted upon by said energyzing means, and
• tool means axially fixed to said connecting means at the anterior end thereof, said tool means being vibrated by the ultrasonic vibration of said vibration means as transmitted by said connecting means.

• connecting means extending through said hollow sleeve, said connecting means being mounted at a spaced distance from the internal wall of said hollow sleeve to thereby form an annular space between said sleeve and said connecting means, said annular space being in fluid communication with said casing, and a nozzle means adjacent said hollow sleeve anterior end for fluid flowing through said space to exit said nozzle means said nozzle means comprising a bushing mounted internally in said hollow sleeve adjacent the open anterior end thereof said bushing having an internal diameter at a spaced distance from said connecting means thereby providing an annular nozzle.
• said connecting means additionally comprising a shank portion extending through said hollow sleeve, a shallow channel longitudinally located thereon extending from the interior of said hollow sleeve and past said bushing for providing an added stream of fluid, and a ring transversely mounted on said shank portion at the nodal point thereof, said hollow sleeve having a transverse slot adapted to accomodate said ring and flow detour means for providing fluid passages around said ring,
• ultrasonic vibration means fixedly connected to said connecting means at the posterior end thereof and adapted to be inserted into said casing into position to be acted upon by said energyzing means, and tool means axially fixed to said connecting means at the anterior end thereof, said tool means being vibrated by the ultrasonic vibration of said vibration means as transmitted by said connecting means.

A method of utilizing fluid in an ultrasonic device and at a work area around the ultrasonic device tool tip, the method comprising

• introducing said fluid into the ultrasonic device
• cooling vibration means within the device by passing said fluid over the vibration means
• cooling a connecting means attached to the vibration means by forcing the fluid through an annular space between the connecting means and a hollow sleeve,
• simultaneously with said step of cooling the connecting means, attenuating vibratory transfer from the connecting means to the sleeve, and
• spraying said fluid in a 360.degree. area about a tool attached to the connecting means.
