1. A device For precise multi-positioning of work three dimensionally and angularly about an axis thereof for machining, grinding and the like, comprising in combination:
- an integral body member having a plurality of surface means arranged in right angle relationship in rectangular form;
a first two of said surface means being in contiguous relation and having uniform width, each of said first two surface means being provided with a pair of parallel transversely extending V-grooves spaced apart a preselected distance and adapted to removably hold positioning rods of selected diameter;
a second two of said surface means in contiguous relation having uniform width less than the width of said first two of said surface means and in symmetrical relation with the first surface means, and second two of said surface means having longitudinally extending V-grooves adapted to axially position a work piece;
one of said second two of said surface means being provided with spaced transverse recesses between ends thereof adapted to receive an index means to selectively angularly position a work piece about its axis;
one of said second two of said surface means including a transverse V-groove adjacent one of said body portions having a first surface means, and a transverse V-groove on said one of said second surface means adjacent to the other of said second surface means.

Abstract
A work holder device providing precise multipositioning of a work piece with respect to three dimensional and angular relationships for the machining, grinding and the like of surfaces on the work piece. A work holder body member of right angle type constructed and arranged to provide holding and securing of a work piece in a multitude of desired positions with a reduced set up time and providing for elimination of some set up steps normally employed in the positioning of a work piece for a working operation.

- an integral body member having a plurality of surface means arranged in right angle relationship in rectangular form;
-
2. In a device as stated in claim 1 wherein at least one of said first surface means is provided on a body portion having a slot therethrough extending diagonally with respect to one of the surface means of each of the first and second surface means for securing said body member at an angle on a work table.
-
3. In a device as stated in claim 1 wherein a body portion providing one of said first surface means is provided with holes arcuately spaced a preselected distance from a reference hole, the holes being adapted to receive pins for supporting a work on said pins at a selected angle.
-
4. In a device as stated in claim 1 wherein at least one of said first surface means includes alignment holes located a selected distance apart and at 45* to a diagonally extending slot through said one of said first surface means.
-
5. In a device as stated in claim 1 including index means having radial holes angularly spaced and adapted to receive a pin, said index means being carried in a transverse recess in a longitudinal V-groove and adapted to hold a work piece;
- said radial holes being so arranged with respect to a stop face on said body member to provide precise angular positioning of said work piece.
-
6. In a multi-purpose work holding means, the combination of:
- an integral body member having two plate-like body portions provided with external planar surfaces lying at right angles to each other;
a web member bridging the included angle between said body portions and having web legs each provided with an external face normal to said planar surface contiguous thereto;
means provided in at least one of said body portions of said body member to precisely locate said body member and work associated therewith on a work table;
said locating means including a pair of alignment holes spaced a selected distance apart on each longitudinal and lateral axis of said body portion, and a through slot in said body portion at 45* to each of said axes and having a slot axis intersecting said longitudinal and lateral axes at a common point of intersection;
pairs of parallel transverse V-groove means spaced apart a selected distance on said planar surfaces and on at least one of said external web member faces; and
longitudinally extending V-groove means on at least one of said external faces of said web member for supporting a cylindrical work piece.
- an integral body member having two plate-like body portions provided with external planar surfaces lying at right angles to each other;
