Abstract
A manual tool useful for scraping, deburring and breaking the sharp edges of sheet material such as metal and glass and the like, formed of an elongated handle shaped to fit within the human hand and a pair of closely adjacent, conventional, wafer-like, hard cutter inserts mounted upon the forward end of the handle. A pair of sockets are formed on the forward end of the handle and each insert fits within a socket and is immovably held therein by means of a conventional fastener. The inserts each have a forwardly extending cutter edge, and the two cutter edges are arranged at an acute angle to form a V-shaped channel between the two inserts. The channel receives and is drawn along the sharp edge of the sheet material. The inserts are removable and replaceable, when desired, with similar inserts.
Claims8
A hand tool useful for manually deburring and for breaking the corners defining sharp edges of sheet material such as sheet metal, sheet glass and the likes, comprising:
- an enlogated handle of a size for fitting within a hand for manually grasping the handle along its length, and with the handle having a forward end forming a head;
- a pair of substantially identical, adjacent sockets formed on the forward end head of the handle, each socket having a forwardly and sidewardly opened portion, and a substantially flat base surface arranged generally in a plane that extends longitudinally of the handle and formed with spaced apart, opposite side wall surfaces extending perpendicularly to the base surface, with the socket side wall surfaces within each socket being acutely angled relative to the forward end of the socket to form an acute angle pair of wall surfaces for receiving and supporting a corner-like portion of an insert;
- a conventional flat, generally wafer-like, hard disposable cutter insert closely fitted within each of said sockets;
- each socket being of a size to receive the insert with a flat face of the insert arranged in contact with the socket base surface and with the socket wall portions engaging opposite edge portions of said insert for removably positioning the insert within the socket, and with each insert having a forward portion extending forwardly of the handle and of the socket and an inner side edge portion extending forwardly of the socket;
- with the side edge portion of one insert being adjacent the side edge portion of the other insert and with the two adjacent side edge portions defining and acute angle spce therebetween with the space angle widening in the forward direction;
- fastening means securing each insert within its socket;
- whereby a conventional cutter insert of a predetermined peripheral shape may be rigidly secured within each socket so that a sharp edge of a sheet may be positioned between the two inner side edge portions of the inserts so that said side edge portions may be manually scraped along said sheet edge for deburring and for breaking the longitudinal corners defining said edge.
A manually operated tool for manually scraping a long, sharp edge of a sheet material work piece, comprising:
- an elongated handle shaped for fitting within a human hand for manually grasping the handle, with the handle having a forward end;
- a pair of wafer-like conventional, flat, hard, disposable cutter inserts mounted upon the forward end of the handle adjacent one another;
- a pair of adjacent sockets formed on the forward end of the handle, with each socket closely receiving and mounting an insert, with the forward end of the sockets being open so that the onserts extend forwardly of the handle and the sockets, and with each socket including a substantially flat base surfce arranged generally in a plane that extends longitudinally of the handle, and the sockets including spaced apart, opposite side wall surfaces extending peripherally to the base surface and generally longitudinally of the handle with said side wall surfces being acutely angled relative to the forward end of the socket to form an acute angle pair of wall surfaces for receiving and supporting a corner-like portion of an insert located upon the base surface;
- removable fastening means securing each insert within its socket so that the insert may be removed and replaced with other similar inserts;
- said inserts each having a side edge portion which extends forwardly of the socket at an acute angle relative to the side edge portion of its adjacent insert, with said side edge portions defining a generally V-shaped channel which opens forwardly of the tool for receiving a work piece edge between the side edge portions, whereby the tool may be manually moved along the length of the work piece edge for deburring or for breaking the work piece sharp edges.
