TITLE GLAZING IMPLEMENT

FIELD OF THE INVENTION

This invention lies in the field of manual implements, in particular implements for use in the work of glazing, that is, setting window and door panes in frames using putty or equivalent.

BACKGROUND

Glazing with putty is a craftsman's or artisan's task now only partially replaced with pre-manufactured profile strips and glazing with putty is still common. The implement used is a putty knife, a knife or spatula of fairly broad blade and a straight edge at the distal part of the blade; appreciable skill is required for its use and those that are not trained in the craft or trade experience difficulty and usually do not achieve a neat and well worked off result. One feature of present times is a decline in the trades and crafts and a falling off of the quality of hand crafted work, including glazing with putty. Amateurs or home do-it-yourself individuals who carry out replacement of broken windows themselves find that they are unable to produce a good result.

There is thus a need for a solution to these problems associated with glazing with putty. In this specification the term "putty" will be used as a convenient term to include any similar substance or material for use in glazing.

THE INVENTION

An implement in accordance with this invention for glazing with putty comprises a blade inclined at an acute angle to a frame, and a handle, in which the distal edge of the blade is preferably parallel to a line where the blade extends from the frame at the said acute angle and spaced from the line by the dimension to which the putty is to be worked.

The distal edge of the blade may be straight, for use where a straight edge of a window is to be glazed along the straight edge; the distal edge (and the line where the blade extends at the acute angle from the frame) as well as the blade itself may be curved, for use where a curved edge of a window (e.g. an arched window) is to be glazed.

This dimension to which the putty is to be worked is equal to the width of the blade which sets the dimension to which the putty is to be worked, measured on the surface of the putty.

The blade is preferably set at an angle of 45 degrees or an angle close to that, e.g. between 30 degrees and 60 degrees, to the frame.

The frame may be a flat panel, its purpose is to be pressed against the glass so that the blade, which works the putty in use, is at 45 degrees (or other suitable angle as mentioned) to the glass; this works the putty to the required angle to the glass, in use.

The blade preferably furthermore has edges that are inclined outwardly away from the frame, selected to form a neat line intersection of the inclined putty surfaces at a corner of the glazing putty. Where the putty is inclined at 45 degrees to the glass, the edges of the blade are inclined at an angle measured on the surface of the blade of 35 degrees to the width direction of the blade (and 55 degrees to a line orthogonal to the width direction of the blade, i.e. a line parallel to the distal edge of the blade).

The handle may be made to extend over the frame region of the implement, in a preferred embodiment the handle extends along the longitudinal direction of the frame.

THE PREFERRED EMBODIMENTS

As shown in figures 1 and 4 to 7, the implement 1 for glazing with putty comprises a blade 2 inclined at an acute angle 3 (see figure 6) to a frame 4, and a handle 5, in which the distal edge 6 of the blade is parallel to a line 7 where the blade extends from the frame at the said acute angle and spaced from the line by the dimension 8 to which the putty is to be worked.

The distal edge of the blade is straight, for use where a straight edge of a window is to be glazed.

This dimension 8 is the width of the blade and sets the dimension to which the putty is to be worked, measured on the surface of the putty.

The blade is set at the angle 3 of 45 degrees.

The frame 4 is a flat panel, its purpose is to be pressed against the glass in use.

The blade has edges 9 and 10 that are inclined outwardly away from the frame, selected to form a neat line intersection of the inclined putty surfaces at a corner of the glazing. The edges of the blade are inclined at an angle 11 measured on the surface of the blade of 35 degrees to the width direction 12 of the blade (and at an angle 13 of 55 degrees to the length direction 14 of the blade).

The handle extends over the frame region of the implement, along the longitudinal direction 14 of the frame. The handle has grooves 16 to make the grip more comfortable and secure.

Figure 2 shows an implement for use in glazing a curved edge, in having a blade 17 that is curved; the curvature may be greater than the curvature of the edge to have putty applied. The distal edge (and the line where the blade extends at the acute angle from the frame) may be curved, for use where a curved edge of a window (e.g. an arched window) is to be glazed.
