ph electrode holder

Claim 1

A DEVICE FOR REMOVABLY POSITIONING A PH GLASS ELECTRODE OR THE LIKE HAVING A CYLINDRICAL PORTION WITH AN ENLARGED BASE, IN A VALVED APERTURE EXTENDING THROUGH THE ALIGNED WITH SAID APERTURE,MEANS FOR SECURING SAID MEMBER TO THE OUTSIDE OF SAID CONTAINER WALL, AN ELONGATED INTERNALLY THREADED SLEEVE EXTERNALLY THREADED AT ITS INNER END SO AS TO BE THREADED INTO SAID ANNULAR MEMBER AND EXTENDING OUTWARDLY FROM SAID WALL AND SAID CONTAINER, AN ELONGATED RETRACTOR NUT HAVING AN EXTERNALLY THREADED PORTION AT ITS INNER END TO BE RECEIVED INSIDE SAID THREADED SLEEVE, AND A FLATTENED ROTATABLE HEAD AT ITS OUTER END,A HOLLOW CYLINDRICAL RETRACTOR MEMBER PROVIDED WITH ENLARGED MEANS AT ITS ENDS FORMING THEREBETWEEN A CIRCUMFERENTIAL GROOVE FOR SAID RETRACTOR NUT TO BE ROTATABLY MOUNTED THEREIN, SAID MEMBER BEING MOVABLE THEREBY SELECTIVELY TO BE DRAWN INTO SAID SLEEVE AND TO BE EXTENDED OUT OF SAID SLEEVE, AND A THREADED CAP AT THE INNER END OF SAID RETRACTOR MEMBER FOR SECURING THE ENLARGED BASE OF SAID ELECTRODE TO THE END OF SAID MEMBER SO THAT THE CYLINDERICAL PORTION EXTENDS AXIALLY THEREFROM, THE LENGTHS OF SAID SLEEVE, NUT, AND RETRACTOR MEMBER BEING GREATER THAN THE LENGTH OF THAT PART OF THE ELECTRODE THAT EXTENDS THROUGHT SAID VALVE, SO THAT, WHEN SAID RETRACTOR MEMBER IS PARTIALLY WITHDRAWN FROM SAID SLEEVE, SAID VALVE MAY BE CLOSE.

Claim 2

A DEVICE FOR REMOVABLY POSITIONING A PH GLASS ELECTRODE OR THE LIKE HAVING A CYLINDRICAL PORTION WITH AN ENLARGED BASE, IN A VALVED APERTURE EXTENDING THROUGH THE ALIGNED WITH SAID APERTURE,MEANS FOR SECURING SAID MEMBER TO THE OUTSIDE OF SAID CONTAINER WALL, AN ELONGATED INTERNALLY THREADED SLEEVE EXTERNALLY THREADED AT ITS INNER END SO AS TO BE THREADED INTO SAID ANNULAR MEMBER AND EXTENDING OUTWARDLY FROM SAID WALL AND SAID CONTAINER, AN ELONGATED RETRACTOR NUT HAVING AN EXTERNALLY THREADED PORTION AT ITS INNER END TO BE RECEIVED INSIDE SAID THREADED SLEEVE, AND A FLATTENED ROTATABLE HEAD AT ITS OUTER END,A HOLLOW CYLINDRICAL RETRACTOR MEMBER PROVIDED WITH ENLARGED MEANS AT ITS ENDS FORMING THEREBETWEEN A CIRCUMFERENTIAL GROOVE FOR SAID RETRACTOR NUT TO BE ROTATABLY MOUNTED THEREIN, SAID MEMBER BEING MOVABLE THEREBY SELECTIVELY TO BE DRAWN INTO SAID SLEEVE AND TO BE EXTENDED OUT OF SAID SLEEVE, AND A THREADED CAP AT THE INNER END OF SAID RETRACTOR MEMBER FOR SECURING THE ENLARGED BASE OF SAID ELECTRODE TO THE END OF SAID MEMBER SO THAT THE CYLINDERICAL PORTION EXTENDS AXIALLY THEREFROM, THE LENGTHS OF SAID SLEEVE, NUT, AND RETRACTOR MEMBER BEING GREATER THAN THE LENGTH OF THAT PART OF THE ELECTRODE THAT EXTENDS THROUGHT SAID VALVE, SO THAT, WHEN SAID RETRACTOR MEMBER IS PARTIALLY WITHDRAWN FROM SAID SLEEVE, SAID VALVE MAY BE CLOSE.
