Grinding stone dressing device

A dressing device for dressing a grinding stone which grinds an edge of a glass pane, said dressing device comprising:

• a plurality of rectangular dressing members;
• a container having a rectangular cross section, said container containing therein said dressing members which are piled;
• a grooved holding member on which said container is mounted, said holding member including a front portion projected forward from a front wall of said container and a rear portion projected rearward from a rear wall of said container;
• means defining in said front and rear walls of said container front and rear rectangular openings whose lower peripheries are bounded by a bottom wall of the groove of said grooved holding member, said front opening being so sized as to pass therethrough each of said dressing members;
• a front lid member connected to said front wall of said container in a manner to adjust the size of said front rectangular opening;
• a pushing plate slidably received in the groove of said rear portion of said holding member, said pushing plate being so sized as to pass through said rear opening;
• a hydraulically operated cylinder having a working stem;
• and
• a structure having one end connected to said pushing plate and the other end connected to said working stem of the cylinder, so that upon energization of said cylinder, said pushing plate is moved between a position wherein a forward end thereof is deeply inserted into said container through said rear opening and another position wherein said forward end is drawn away from said container.

A window glass grinding device having a pivotal arm on which a circular grinding stone is rotatably mounted;

• a dressing device for dressing said circular grinding stone;
• a pivot support for mounting said dressing device to said pivotal arm in a manner to adjust the position of said dressing device relative to said pivotal arm;
• said pivot support comprising
• a base plate secured to said pivotal arm;
• a pivoting arm pivotally connected to said base plate and secured to said dressing device;
• and
• an angular position adjuster for adjusting the angle defined between said base plate and said pivoting arm;
• said angular position adjuster comprising
• a bolt pivotally connected to a free end of said pivoting arm;
• means defining in said base plate an aperture through which said bolt passes;
• and
• at least two nuts engaged with said bolt having the apertured portion of said base plate put therebetween;
• said dressing device comprising
• a container in which dressing members are contained and piled;
• a grooved holding member on which said container is mounted, said holding member including a front portion projected forwardly from a front all of said container and a rear portion projected rearwardly from a rear wall of said container;
• means defining in said front and rear walls of said container front and rear openings whose lower peripheries are bounded by a bottom wall of the groove of said grooved holding member, said front opening being so sized as to pass therethrough each of said dressing members;
• a pushing plate slidably received in the groove of said rear portion of said holding member, said pushing plate being so sized as to pass through said rear opening;
• and
• means for reciprocatively moving said pushing plate along said groove between a position wherein a forward end of said pushing plate is deeply inserted into said container through said rear opening and another position wherein said forward end is drawn away from said container.
