Abstract: A device or tool setter has the purpose of setting the position of a support bar, adjustably connected to a grinding machine, in relation to a rotatable grindstone of the machine for obtaining a desired edge angle of a tool supported for grinding by the support bar. The device is provided with discs for defining two contact points with the grindstone and a hole for connection to the support bar.

Abstract: A device for sharpening a twist drill pointby means of a rotating grindstone (12) in a grinding machine comprises a base plate (14) lockably articulated around an axis parallel with the axis of the grindstone (12), a drill holder (16) for releasably holding a twist drill (1) to be sharpened, and a guide member (15). The guide member has a back plate (21) and a front plate (22), lockably rotatable in relation to each other. The back plate (21) is connected to the base plate (14) for movements in the direction of the grindstone axis, and the front plate (22) has guide means (28, 29) for slidably guiding the drill holder (16) in the general direction towards and away from the grindstone (12).

Abstract: A device for grinding a cutting tool uses a rotatable grindstone and a tool holder for mounting the cutting tool. The device guides the tool, mounted in the tool holder, along an intended plane, which is tangential to a peripheral surface of the rotatable grindstone, using a practically linear contact between the rotatable grindstone and the cutting tool. By moving the tool holder, with the mounted cutting tool, along the intended plane, this plane is transferred to an unbevelled side of the cutting tool.

Abstract: A grinding jig for use in the grinding of a straight edge woodworking tool on the peripheral surface of a rotating grindstone in a grinding machine. The grinding machine has a cylindrical support bar parallel with the rotation axis of the grindstone. The jig includes a base, which is parallel with the support bar and is intended for slidable and rotational mounting on the support bar, and a clamp, wherein the tool is attached between the base and the clamp. The grinding jig has a support surface on the base for supporting the face of the tool opposite its bevel.

Abstract: A truing tool for a grindstone (1) is intended for attachment to a universal support (3) in the form of a cylindrical rod of a grinding machine in parallel with the rotation axis of the grindstone. It has—in a holder (12) therefore—a cutting tip (13) for truing engagement with the grindstone. The holder (12) is movably connected to a yoke (10)—to be attached to the universal support (3)—by a feeding rod (14), which is rotatably supported by the yoke (10) and is in engagement with a threaded bore in the holder (12), for its movement in relation to the yoke transversely of the grindstone (1).

Abstract: A grinding jig (5) is to be attached on an edge tool (4) to be ground on a rotating grindstone (2) in a grinding machine (1), having a support means (3) in the vicinity of the grindstone. The jig is split by having a base portion (6) and two parallel open yokes (8, 9) extending therefrom. A screw (7) for clamping the tool (4) against the bottoms of the yokes is provided in the base portion between the two yokes.

Abstract: Jig for grinding sharp-edged tools. The jig consists of a housing in the form of a casing designed with a passage running through it whose at least one end is flat, plus a seat, also in the form of a casing designed with a passage running through it, located in the passage of the housing and lockable in this housing in an inclined position in relation to the passage in the housing, whereby the seat is provided with a clamping device (4) for firmly holding a tool that is to be ground so that it extends through the passage of the seat, and that the seat has such a length that one end of it extends out beyond the housing at the flat end of the housing.

Abstract: A jig for grinding gouges in cooperation with a grindstone or the like. The jig includes a support, which can be fixed positionally in relation to the grindstone. The support includes a supportive part that extends generally parallel to the grindstone axle. A bearing sleeve is mounted on the supportive part for pivotal movement in a plane generally perpendicular to the grindstone axle. A rod is included for displacement in the plane of the bearing sleeve. The rod includes a pivotal locking stirrup for locking the gouge to the jig.

Abstract: Angle gauge for grinding the lip of sharp-edged tools whereby an adjustable first device is arranged on the frame at one end of the frame that during measurement is intended to be supported against the periphery of the grinding wheel and that through adjustment varies the distance between the said one end and the periphery of the grinding wheel, and an adjustable and rotatable second device is arranged at the other end of the frame and provided with a flat edge that extends towards the periphery of the grinding wheel and that during measurement abuts with periphery of the grinding wheel with the corner edge that faces the first device in such a manner that the flat edge forms an angle with the periphery of the grinding wheel where this angle defines the cutting angle.

Abstract: The present invention teaches a female part that can locked in selected positions on a round rod. The female part includes a hollow passageway into which a locking screw can be screwed in a generally radial direction into engagement with the rod. When seen in a cross section, the passageway includes two flat surfaces which slope towards one another symmetrically in relation to a diametrical plane. The angle defined by the surfaces with the plane lies between 2.5' and 15.0'. The locking screw enters the passageway in the wider part between the surfaces.
