Abstract
Abstract A mounting is provided for mounting a tuning fork type crystal vibrator in a hermetically sealed oscillator envelope. The mounting comprises a pair of discrete elements depending from the oscillator terminal tag and each element includes a shoulder connected thereto, an arm connected to the shoulder and forming an elbow therewith, an inwardly arranged finger connected to the arm and forming an elbow therewith, a downwardly arranged flange from the finger and a cradle member depending laterally extending between the flanges and connecting the flanges. The mounting elements are arranged in the oscillator envelope so that each cradle member supports a tine of the tuning fork vibrator.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
An improved oscillator for a timepiece comprising a terminal tag, contacts mounted in said terminal tag, an evacuated envelope hermetically sealed to said tag, a tuning fork type crystal vibrator mounted in said envelope, and a mounting for said crystal comprising a pair of connected elements depending from said terminal tag, each element including a shoulder connected to said terminal tag, an arm connected to said shoulder and forming an elbow therewith, an inwardly arranged finger connected to said arm and forming a second elbow therewith, a downwardly arranged flange depending from said finger, and a cradle member depending laterally between said flanges and connected respectively thereto for supporting said tuning fork type crystal vibrator.
Claim 2
Dependent Claim
115 words
An improved oscillator for a timepiece comprising a terminal tag, contacts mounted in said terminal tag, an evacuated envelope hermetically sealed to said tag, a tuning fork type crystal vibrator mounted in said envelope, and a mounting for said crystal comprising a pair of connected elements depending from said terminal tag, each element including a shoulder connected to said terminal tag, an arm connected to said shoulder and forming an elbow therewith, an inwardly arranged finger connected to said arm and forming a second elbow therewith, a downwardly arranged flange depending from said finger, and a cradle member depending laterally between said flanges and connected respectively thereto for supporting said tuning fork type crystal vibrator.
Claim 3
Dependent Claim
27 words
The improved oscillator as claimed in claim 1 wherein said pair of connected elements are substantially coplanar and substantially mirror image projections relative one to the other.
Claim 4
Dependent Claim
35 words
The improved oscillator as claimed in claim 1 wherein respective arms of said respective connected elements have a resilient spring-like character wherein the resiliency thereof is normal to the vibrating direction of said crystal vibrator.
Claim 5
Dependent Claim
35 words
The improved oscillator as claimed in claim 1 wherein said flanges of said respective connected elements have a resilient spring-like character and the resilience therein is parallel to the vibrating direction of said vibrating crystal.
Claim 6
Dependent Claim
27 words
The improved oscillator as claimed in claim 1 wherein the root of said vibrating tuning fork type crystal is supported in said cradle member of said mounting.
Claim 7
Dependent Claim
49 words
The improved oscillator as claimed in claim 1 wherein said oscillator envelope comprises a pair of shallow, concave sections provided with respective outwardly extending rims, said shallow, concave sections being engaged along said respective rims thereof by a cold weld, said engaged rims thereby forming an outwardly extending flange.
Claim 8
Dependent Claim
118 words
A mounting for a tuning fork type quartz crystal vibrator having equispaced tines joined at a root of the type employed in a timepiece comprising a pair of substantially coplaNar integrally connected elements in spaced relationship, one with the other, said pair being substantially mirror image projections, one of the other, each element including a shoulder, an arm connected to said shoulder and forming an elbow therewith, an inwardly arranged finger connected to said arm and forming a second elbow therewith, a downwardly arranged flange depending from said finger and a cradle member depending laterally from said flanges for supporting a tine of said tuning fork type crystal vibrator, said cradle member providing a connection between said flanges.
Claim 9
Dependent Claim
118 words
A mounting for a tuning fork type quartz crystal vibrator having equispaced tines joined at a root of the type employed in a timepiece comprising a pair of substantially coplaNar integrally connected elements in spaced relationship, one with the other, said pair being substantially mirror image projections, one of the other, each element including a shoulder, an arm connected to said shoulder and forming an elbow therewith, an inwardly arranged finger connected to said arm and forming a second elbow therewith, a downwardly arranged flange depending from said finger and a cradle member depending laterally from said flanges for supporting a tine of said tuning fork type crystal vibrator, said cradle member providing a connection between said flanges.
Claim 10
Dependent Claim
32 words
The mounting as claimed in claim 7 wherein respective arms of said elements have a resilient spring-like character wherein the resiliency thereof is normal to the vibrating direction of said crystal vibrator.
Claim 11
Dependent Claim
33 words
The mounting as claimed in claim 7 wherein said flanges of said respective elements have a resilient spring-like character and the resilience therein is parallel to the vibrating direction of said vibrating crystal.
