Abstract
Abstract A versatile rigid horn assembly for distributing ultrasonic energy from at least one source to a plurality of spaced work areas is provided. This rigid horn assembly includes an elongated tool holder having an input region at one end and an output region at the other end. The tool holder is a horn of suitable metal and will have a length of at least one acoustic half wavelength, or any desired number of integral half wavelengths. Secured to and extending from the output end are rigid tool members, each of which is a horn and has a length of at least one acoustical half wavelength. Tool members may have lengths of integral half wavelengths, it being understood that tool members need not necessarily be of the same shape or length. The drawings illustrate various arrangements of tool members. The output end of a tool holder has means permitting attachment of a plurality of tool members, the means being arranged so that one or more various tool members may be disposed to provide different tool member patterns. The means for attaching a tool member to a tool holder includes threaded metal members each of which may be a threaded stud extending into a tapped recess in the tool holder or elongated bolts each having an enlarged head disposed in bores extending longitudinally of the tool holder and having an interior shouldered part for each bore. Alternatively, a tool member may include an integral threaded boss, or the tool holder and tools may be of brazable material and secured by brazing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
341 words
An ultra-sonic tool system for industrial processing with acoustic energy, said system comprising an elongated, straight, rigid, unitary tool holder of rigid material having a longitudinal axis and a length of an intergral number of halfwave lengths at the operating frequency, the transverse dimensions being so proportioned to the length thereof as to minimize undesired modes of transmission other than along the tool holder length, said tool holder having only two ends shaped to provide finished flat sonic energy input and output areas, the tool holder providing a common transmission path for all sonic energy from the input to the output thereof, threaded means at the input end for coupling at least one source of sonic energy thereto; at least two, elongated, rigid tool members laterally spaced from each other each rigidly secured directly to a sonic output area of the tool holder, each tool member having at one end a sonic input area conforming to a sonic tool holder output area in the secured positions of the tool holder and tool members, each tool member having a sonic energy working output tip at its other end, the tool holder output area being great enough to accommodate a plurality of laterally offset secured tool members arranged to create a desired pattern of work areas, each tool member having a length of an integral number of halfwave lengths, said tool holder and tool members being each resonant to the acoustic energy so that efficient transmissions of sonic energy to the work areas result, each tool member being susceptible to individual design with regard to tool member contours, amplitude of sonic energy at a work area and physical length of a tool member, said tool system being sufficiently rigid so that it may be pressed against work without accessories for guiding tool members, at least one of said tool members having at least part of its length of a substantially different transverse dimension than corresponding parts of other tool members so that vibration amplitude differs from other tool members at the work areas.
Claim 2
Dependent Claim
319 words
An ultra-sonic tool system for industrial processing with acoustic energy, said system comprising an elongated, straight, rigid, unitary tool holder of rigid material having a longitudinal axis and a length of an integral number of half-wave lengths at the operating frequency, the transverse dimensions being so proportioned to the length thereof as to minimiZe undesired modes of transmission other than along the tool holder length, said tool holder having two ends shaped to provide finished flat sonic energy input and output areas, the tool holder providing a common transmission path for all sonic energy from the input to the output thereof, threaded means at the input end for coupling at least one source of sonic energy thereto; at least two, elongated, rigid tool members laterally spaced from each other rigidly secured directly to sonic output areas of the tool holder, each tool member having at one end a sonic input area conforming to a sonic tool holder output area in the secured positions of the tool holder and tool members, each tool member having a sonic energy working output tip at its other end, the tool holder output area being great enough to accommodate a plurality of laterally offset secured tool members arranged to create a desired pattern of work areas, each tool member having a length of an integral number of half-wave lengthss, said tool holder and tool members being each resonant to the acoustic energy so that efficient transmissions of sonic energy to the work areas result, each tool member being susceptible to individual design with regard to tool member contours, amplitude of sonic energy at a work area and physical length of a tool member, said tool system being sufficiently rigid so that it may be pressed against work without accessories for guiding tool members, at least one of said tool members having its working end at a level different from that of other tool members.
Claim 3
Dependent Claim
64 words
The system according to claim 7, wherein said tool holder has a portion of its output face at a level different from other portions so that even if similarly dimensioned tool members are used, the working ends of such tool members are at different levels, the difference in level at the output of the tool holder being small in comparison to the operating wavelength.
Claim 4
Dependent Claim
335 words
An ultra-sonic tool system for industrial processing with acoustic energy, said system comprising an elongated, straight, rigid, unitary tool holder of rigid material having a longitudinal axis and a length of an integral number of half-wave lengths at the operating frequency, the transverse dimensions being so proportioned to the length thereof as to minimize undesired modes of transmission other than along the tool holder length, said tool holder having two ends shaped to provide finished flat sonic energy input and output areas, the tool holder providing a common transmission path for all sonic energy from the input to the output thereof, threaded means at the input end for coupling at least one source of sonic energy thereto; at least two, elongated, rigid tool members laterally spaced from each other rigidly secured directly to a sonic output area of the tool holder, each tool member having at one end a sonic input area conforming to a sonic tool holder output area in the secured positions of the tool holder and tool members, each tool member having a sonic energy working output tip at its other end, the tool holder output area being great enough to accommodate a plurality of laterally offset, secured tool members arranged to create a desired pattern of work areas, each tool member having a length of an integral number of half-wave lengths, said tool holder and tool members being each resonant to the acoustic energy so that efficient transmissions of sonic energy to the work areas result, each tool member being susceptible to individual design with regard to tool member contours, amplitude of sonic energy at a work area and physical length of a tool member, said tool system being sufficiently rigid so that it may be pressed against work without accessories for guiding tool members, at least two sonic flat output area portions of the tool holder lying in different non-parallel planes so that secured tool members have their respective lengths in non-parallel relation, the angular departure from parallelism being small.
