Abstract

Apparatus for fashioning a pointed end on a stake includes a base on which is mounted a rotatably driven slotted circular disk having secured to one side thereof a plurality of cutting blades co-disposed in a radially outward arrangement within a cutting plane of the disk. A feed table is displaceably mounted on the base adjacent the cutting plane of the disk and supports a hollow cylinder having open ends for receiving a wooden stake and retaining a free end thereof in a predetermined angular cutting engagement with the cutting plane. Forward travel of the stake through the cylinder is limited by a stop member and lateral displacement of the stake relative to the cutting plane is provided by a handle operated cam that controllably moves the feed table to establish a predetermined depth of cut. The stake is rotated within the cylinder either manually or by a motor driven rotator which results in pinpointing the extended end of the stake.

Dependent claims

Apparatus for pinpointing a workpiece, comprising in combination:

a base having a mounting surface thereon;
cutting means rotatably supported on the mounting surface, said means including a flat disk having at least one cutting member radially disposed and secured thereon in a cutting plane of the disk;
drive means mounted on the base and coupled to the cutting means for rotatably driving the disk;
a feed table disposed on the mounting surface in adjacent relation to the cutting plane of the disk;
stand means affixed to the mounting surface in spaced adjacent relation with the cutting plane of the disk, and in supporting relation with the feed table;
carriage means disposed between the stand means and the feed table for positionably supporting the feed table with respect to the cutting plane of the disk;
means cooperatively engaging the stand means and feed table for returnably advancing the table towards the cutting plane of the disk via the carriage means;
and
a channel member mounted on the feed table, the member having open ends adapted to receive and supportively engage the workpiece and to retain the free end thereof in predetermined angular cutting engagement with the cutting plane of the disk.
