Abstract
Apparatus and method for setting knife blade depth. The apparatus comprises a magnification device and a removable tray in operative engagement with a digital micrometer. The method comprises the steps of positioning the edge of the knife holder flush with a fixed vertical plane extending through a reticle axis within the magnification device, zeroing the micrometer, rotating the micrometer handle until the tray and edge of the knife holder have moved a predetermined distance away from the fixed plane, and adjusting the knife blade until the edge of the knife blade is flush with the fixed plane.
Claims16
Apparatus for setting a knife blade which is movable relative to a blade holder and which has an outermost edge or tip, said apparatus setting the length of extension of said outermost edge or tip of said blade relative to an edge of said blade holder, comprising:
- a tray for receiving said blade holder fixedly thereon, said tray with said blade holder fixedly attached being movable with respect to a fixed plane, said outermost edge or tip of said blade aligned with said fixed plane;
- and
- means in operative engagement with said tray for moving said tray with said blade holder fixedly thereon a predetermined distance relative to sasid fixed plane, thereby moving said outermost edge of said blade holder said predetermined distance away from said fixed plane, said outermost edge of said blade thereafter being moved with respect to said blade holder by adjustment means until said outermost edge aligns with said fixed plane, said length of extension of said outermost edge moved by said adjustment means thereby being equivalent to said predetermined distance.
Apparatus for setting a knife blade wherein an edge of a holder of said blade is movable relative to said blade and said blade has an outermost edge or tip, said apparatus setting the length of extension of said outermost edge or tip of said blade relative to said edge of said blade holder, comprising:
- a tray for receiving said blade holder fixedly thereon, said tray, with said blade holder fixedly attached, being movable with respect to a fixed plane, said outermost edge or tip of said blade aligned with said fixed plane;
- and
- means in operative engagement with said tray for moving said tray with said blade holder fixedly attached thereon a predetermined distance relative to said fixed plane, thereby moving said outermost edge or tip of said blade said predetermined distance away from said fixed plane, said outermost edge of said blade holder thereafter being moved with respect to said blade by adjustment means until said blade holder edge aligns with said fixed plane, said length of extension of said outermost edge or tip thereby being equivalent to said predetermined distance.
A method for setting a knife blade which is movable relative to a blade holder, said method setting the length of extension of an outermost edge or tip of said blade away from an edge of said blade holder, comprising the steps of:
- (a) positioning said blade holder on a tray whereby said edge of said holder is aligned with a fixed plane;
- (b) moving said tray a predetermined distance relative to said fixed plane, thereby moving said edge of aid blade holder away from said fixed plane by said predetermined distance;
- and
- (c) moving said outermost edge or tip of said blade relative to said blade holder until said outermost edge or tip of said blade aligns with said fixed plane, said outermost edge or tip extending thereby a distance equivalent to said predetermined distance.
A method for setting a knife blade which is movable relative to a blade holder, said method setting the length of extension of an outermost edge or tip of said blade away from an edge of said blade holder, comprising the steps of:
- (a) engaging a tray with a digital micrometer adpated for moving said tray a predetermined distance;
- (b) positioning said blade holder on said tray whereby said edge of said holder is aligned with a fixed vertical plane;
- (c) focusing a magnifying means on said edge of said holder, said magnifying means including a reticle having an axis through which said fixed vertical plane extends;
- (d) moving said tray said predetermined distance relative to said fixed plane, thereby moving said edge of said holder away from said fixed vertical plane by said predetermined distance;
- (e) focusing said magnifying means on said outermost edge or tip of said blade;
- and
- (f) moving said outermost edge or tip of said blade relative to said blade holder until said outermost edge or tip of said blade is aligned with said fixed vertical plane, said outermost edge or tip extending thereby a distance equivalent to said predetermined distance.
A method for setting a knife blade, wherein an edge of a holder of said blade is movable relative to said blade, said method setting the length of extension of an outermost edge or tip of said blade away from said edge of said blade holder, comprising the steps of:
- (a) positioning said blade holder on a tray whereby said outermost edge or tip of said blade is aligned with a fixed plane;
- (b) moving said tray a predetermined distance relative to said fixed plane, thereby moving said outermost edge or tip of said blade away from said fixed plane by said predetermined distance;
- and
- (c) moving said blade holder edge relative to said blade until said blade holder edge is aligned with said fixed plane, said outermost edge or tip extending thereby a distance equivalent to asid predetermined distance.
A method for measuring the length of extension of an outermost edge or tip of a blade away from an edge of a blade holder, comprising the steps of:
- (a) engaging a tray with a digital micrometer adapted for moving said tray relative to fixed plane;
- (b) positioning said blade holder on said tray whereby said outermost edge or tip of said holder is aligned with said fixed plane;
- (c) focusing a magnfiying means on said edge of said holder, said magnifying means including a reticle having an axis through which said fixed plane extends;
- (d) moving said tray relative to said fixed plane until said outermost edge or tip of said blade is aligned with said fixed plane;
- and
- (e) reading the measurmenet reflected on a display of said digital micrometer.
Apparatus for setting a knife blade which is movable relative to a blade holder and which has an outermost edge or tip, said apparatus setting the length of extension of said outermost edge or tip of said blade relative to an edge of said blade holder, comprising:
- a base;
- a table connected to said base;
- a tray removably connected to said table for receiving said blade holder thereon, means in operative engagement with said tray for moving said tray with respect to a fixed plane said outermost edge or tip of said blade aligned with said fixed plane;
- means connected to said tray for securing said blade holder fixedly to said tray;
- means mounted to said base for magnifying said outermost edge or tip of said blade and for magnifying said blade holder;
- a digital micrometer connected to said table having a spindle in operative engagment with said tray for moving said tray with said blade holder fixedly attached thereon a predetermined distance relative to said fixed plane, thereby moving said edge of said blade holder said predetermined distance away from said fixed plane said outermost edge or tip of said blade thereafter being moved with respect to said blade holder by adjustment means until said blade edge aligns with said fixed plane, said length of extension of said outermost edge or tip thereby being equivalent to said predetermined distance;
- and
- means for maintaining said spindle in operative engagement with said tray comprising a rod connected to said table, a sleeve about said rod having a sleeve pin extending outward therefrom and a lip, said sleeve pin abutting a side of said tray, and a spring about said sleeve intermediate said lip and a rod pin extending outward from said rod.
