Abstract
Abstract A method of assembling parts is provided in which a pair of interfitting surfaces adapted for press fitting are formed on the two parts, a driving force is applied to the two parts urging them axially together while a superposed vibrating force is applied to at least one of the two parts to cause the interfitting parts to engage and dipping said parts into a bath of molten metal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts, one inner and one outer to be joined in telescoping arrangement a pair of interfitting surfaces adapted for press fitting with an open cup like recess between them; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing ultrasonic energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; and c. dipping said interfitted parts into a bath of molten metal to thereby fill the resulting cup-like recess and to finished said fitted joint.
Claim 2
Independent Claim
113 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts, one inner and one outer to be joined in telescoping arrangement a pair of interfitting surfaces adapted for press fitting with an open cup like recess between them; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing ultrasonic energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; and c. dipping said interfitted parts into a bath of molten metal to thereby fill the resulting cup-like recess and to finished said fitted joint.
Claim 3
Independent Claim
111 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting in telescoping arrangement with a vented cup like recess between them; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing vibratory energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; and c. dipping said interfitted parts into a bath of molten metal which is ultrasonically activated to fill the resulting cup-like recess and to finished said fitted joint.
Claim 4
Independent Claim
111 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting in telescoping arrangement with a vented cup like recess between them; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing vibratory energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; and c. dipping said interfitted parts into a bath of molten metal which is ultrasonically activated to fill the resulting cup-like recess and to finished said fitted joint.
Claim 5
Independent Claim
137 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting spaced from the end of the outer of said two parts and to define an open cup-like recess between said parts; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing ultrasonic energy to at least one of said parts to cause the interfitting surfaces to engage said parts into a press fitted arrangement thereby forming a fitted joint, said superposed ultrasonic force being applied to the parts being joined in the direction of said driving force; and c. dipping said interfitted parts into a bath of molten metal to fill the resulting cup-like recess and to finish said joint.
Claim 6
Independent Claim
137 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting spaced from the end of the outer of said two parts and to define an open cup-like recess between said parts; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing ultrasonic energy to at least one of said parts to cause the interfitting surfaces to engage said parts into a press fitted arrangement thereby forming a fitted joint, said superposed ultrasonic force being applied to the parts being joined in the direction of said driving force; and c. dipping said interfitted parts into a bath of molten metal to fill the resulting cup-like recess and to finish said joint.
Claim 7
Independent Claim
129 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting in telescoping arrangement with a vented cup like recess between them; b. apPlying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing vibratory energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; said superposed vibratory force being applied to the parts being joined in a direction transverse to the direction of said driving force; and c. dipping said interfitted parts into a bath of molten metal to thereby fill the resulting cup-like recess and to finish said joint.
Claim 8
Independent Claim
129 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting in telescoping arrangement with a vented cup like recess between them; b. apPlying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing vibratory energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; said superposed vibratory force being applied to the parts being joined in a direction transverse to the direction of said driving force; and c. dipping said interfitted parts into a bath of molten metal to thereby fill the resulting cup-like recess and to finish said joint.
Claim 9
Independent Claim
111 words
A method of assembling joints comprising the steps of: a. forming on the ends of two parts to be joined a pair of interfitting surfaces adapted for press fitting in telescoping arrangement, said interfitting parts forming a pocket between said parts adapted to receive solder; b. applying a driving force to the said two parts urging the interfitting surfaces together while simultaneously superposing vibratory energy to at least one of said parts to cause the interfitting surfaces to engage into telescoping arrangement and to form a fitted joint; and c. dipping said interfitted parts into a bath of molten metal to thereby fill said resulting pocket and thereby finish said joint.
Claim 10
Independent Claim
111 words
