Abstract
A tool for use in removing glazing has a head including a conical point of substantial length and a shank connected to a straight handle with the point disposed towards but angled away from the handle at an angle that does not exceed 30.degree.. The maximum diameter of the point is substantially less than the cross section of the glazing and the angle of taper of the point is such that the point may be drawn with moderate pulling forces lengthwise through the glazing with radial expanding stresses resulting that are adequate to rupture the glazing.
Claims11
A tool for use in removing glazing from a pane-receiving seat having each of its sides defined by walls disposed at right angles to each other, said tool including a head including a straight conical point and a shank of a diameter substantially less than the cross section of the glazing and of substantial length in relation to the diameter thereof, and a handle to which the shank is secured with said point disposed towards but angled away from said handle to provide an angular relationship that does not exceed 30.degree. between the point and the line of force which is generated when the handle is manually held and pulled lengthwise of the glazing with the point in contact with an end of the glazing and parallel to said sides and close to one of them, the angle of taper and the length and diameter of said point such as to enable radial expanding stresses adequate to rupture the glazing to be developed with a pulling force that can be readily applied and controlled.
