Workpiece positioning device

A workpiece positioning device for precisely positioning a workpiece to be worked upon by a power tool comprising:

• a stationary base,
• an elongated locator member carried by the base,
• said locator member having a set of axially aligned spaced-apart apertures therein,
• a fence having a surface thereon for abutting against a workpiece,
• said fence being disposed adjacent to the locator member for limited slideable movement right and left thereof,
• said fence having a set of axially aligned spaced-apart through-apertures therein equal in diameter to the apertures in the locator member,
• said fence being incrementally positionable relative to the locator member by alignment of one of the apertures therein with one of the apertures in said locator member,
• the spacing of the apertures in the fence and the spacing of the apertures in the locator member being different from each other by an amount equal to a precise predetermined distance to facilitate fine positioning of the fence relative to the locator member, and
• whereby a workpiece abutting the fence will be exactly located in the precise position selected therefor.

A workpiece positioning device for precisely positioning a workpiece to be worked on by a power tool comprising:

• a stationary base having a cavity therein,
• an elongated locator member disposed in said cavity for limited slideable movement right and left of said base,
• said locator member having a front portion and a rear portion thereof,
• said rear portion of said locator member having a set of axially aligned spaced-apart vertical apertures therein,
• an elongated scale made fast to the base and disposed above the rear portion of said locator member,
• a set of axially aligned spaced-apart vertical through-apertures in said scale equal in diameter and in number to the apertures in the rear portion of said locator member,
• said front portion of said locator member having a set of axially aligned spaced apart blind-ended horizontal apertures therein,
• a fence having a surface thereon for abutting against a workpiece,
• said front portion of said locator member having a cavity therein,
• a portion of said fence being disposed in the cavity in said front portion of said locator member for limited slideable movement right and left of said locator member,
• a set of axially aligned spaced-apart horizontal through-apertures in said fence equal in diameter to said apertures in the front portion of said locator member,
• said fence being incrementally positionable relative to the locator member by alignment of one of the apertures therein with one of the apertures in said locator member,
• a first pin means extendable through the fence and into one of the apertures in the front portion of the locator member for fixing whichever position of the fence is selected,
• the spacing of the apertures in the fence and the apertures in the front portion of the locator member being different from each other by an amount equal to a first precise predetermined distance to facilitate fine positioning of the fence relative to the locator member,
• said locator member being incrementally positionable relative to the scale by alignment of one of the apertures in said rear portion thereof with one of the apertures in said scale,
• a second pin means extendable through the scale and into one of the apertures in said rear portion for fixing whichever position of the locator member is selected,
• the spacing of the apertures in the scale and the apertures in the rear portion of the locator member being different from each other by an amount equal to a second precise predetermined distance to facilitate precision positioning of the locator member relative to the scale,
• the second precise predetermined distance being more precise than the first precise predetermined distance, and
• whereby a workpiece abutting the fence will be exactly located in the precise position desired therefor.
