Abstract

A hand tool is disclosed herein for removing caulking having a cutting head attached to one end of a handle. The cutting head includes a pair of converging sidewalls terminating in a rounded section wherein the opposing surfaces of the sidewalls define an elongated, open-ended passageway for accommodating the collection and dispersal of caulking and debris. A portion of the cutting head provides a pair of rearward sloping cutting edges so that a forward pointed end is provided for initially dislodging previously installed grout, caulking or the like. Power mechanism may be employed to automatically operate the tool cutting head, if desired.

Claims

1. A tool for removing sealing compound or the like comprising the combination of:

an elongated handle;

a tool head fixly secured to one end of said handle;

said tool head comprising;

a body having a substantially V-shaped cross section sidewalls formed with an open-ended passageway extending along its entire length for accommodating a continuous strip of removed sealing compound;

said body further provided with at least two pointed ends defined by upwardly, angularly sloping cutting edges leading toward said one end of the handle;

said body is composed of a thin-walled sheet folded about a base line extending along the center of said head and constituting the apex of said V-shaped cross section whereby said two pointed ends are defined at the opposite ends of said base line lying in the plane of longitudinal center axis of said head and are defined by cutting edges upwardly diverging from said two pointed ends respectively;

said open-ended passageway is defined by the interior opposing surfaces of said sidewalls of said body;

said body further includes an outwardly flared attachment portion interconnecting said sidewalls to said handle; and

said cutting edges extending from each of said two pointed end and said base line are angularly disposed with respect to each other.

2. The invention as defined in claim 1 wherein said handle is adapted for connection with a suitable power means.

3. The invention as defined in claim 1 wherein said base line is substantially longer than said attachment portion.

4. The invention as defined in claim 3 wherein said handle is angularly disposed with respect to said base line.

5. The invention as defined in claim 4 wherein said pointed ends provide encise means for initially separating sealing compound from its bed so as to form said continuous strip of removed sealing compound.
