GLAZING TOOLS Filed Oct. 6, 1951 Dm l'frl' Vai/ INVENTOR ATTORNEYS United States Patent This invention relates to new and useful improvements in glazing tools.

One object of the invention is to provide an improved glazing tool or putty knife which is so constructed that excess putty may be removed from a glass pane simultaneously with the application of and smoothing of the putty.

Another object of the invention is to provide an improved glazing tool or implement having a pair of blades disposed in angular relationship and having their Work engaging edges angularly disposed for coaction to apply and smooth glazing material and remove excess material from a Windowpane in one continuous operation.

A particular object of the invention is to provide an improved glazing tool, of the character described, which includes a glazing blade having an edge for applying and smoothing putty and an auxiliary blade having an edge disposed in angular relation and close proximity to the glazing blade and its edge for engaging a windowpane to remove excess putty therefrom, said glazing blade having a projecting portion adjacent the auxiliary blade edge to facilitate use of the tool in the corners of windowpanes.

An important object of the invention is to' provide an improved tool, of the character described, wherein the glazing blade has an edge for bearing against the Window pane and cutting the putty, the cutting edge being formed on the projecting portion of said blade substantially between its smoothing edge and the edge of the auxiliary blade whereby the putty may be smoothed and cut in a substantially straight=line movement in the corners as well as along the margins of the windowpane.

A further object of the invention is to provide an improved tool, of the character described, wherein the edge of the auxiliary blade substantially intersects the cutting edge of the glazing blade for coacting therewith in removing excess putty from the windowpane.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understoodfrom a reading of the following specification and by reference to the accompanying drawing, wherein examples of the invention are shown, and wherein:

Fig. l is a perspective view of a glazing tool constructed in accordance with the invention and showing its: relation to the lower corner of a window frame and its glass pane,

Fig. 2 is a perspective view of one end of the tool showing its relation to" the upper corner of a window frame and its pane,

Fig. 3 is an underside plan view of oneend of the tool,

Fig. 4 is a transverse, sectional view of the tool, taken on the line 4-4 of Fig. 2,

Fig. 5 is a perspective view of one end of the glazing blade of the tool with the auxiliary blade removed, and

Fig. 6 is an underside plan view of a portion of one end of the tool, showing a slight modification.

In the drawing, the numeral 1i} designates an implement or tool for glazing a conventional glass Windowpane 11 in the frame 12 of a sash, door or other closure. The tool 19 is in the form of a knife and includes a fiat, thin, glazing blade or member 13 which may be formed of metal, plastic or other suitable material. Although the form of the tool is subject to variation, it is desirable to provide one of the blades 13 at each end of said tool and connect said blades by an intermediate handle portion M whereby the tool is double-ended or reversible. Use of the tool is facilitated by disposing the blades at an angle to the handle portion 14, but such angular relationship is not essential. The blades are preferably coplanar with the handle portion and project at obtuse angles from the ends, and from the same side of said handle portion. Thus, the blades extend at obtuse angles to each other and occupy opposed or reversed positions when the tool is inverted or turned.

Each blade 13' has a transverse straight edge 15 at its outer end for applying and smoothing putty or other glazing material 16 including the squaring or cutting out of the putty at the corners of the pane. Que corner, preferably the inner corner or the left-hand corner of the upper blade, is cut away or removed or bevelled or rounded to provide a corner edge 17 of relatively short length for bearing against the pane 11 to cut the putty along a line 12; of demarcation between said pane and putty. A substantially upright plate 19 is suitably secured to the upper surface of the blade for adjustably supporting an auxiliary scraping blade or member 20. The plate 19 extends at substantially a right angle to the corner edge 17' so as to be disposed diagonally of the blade and its edge 15. For clamping the member 20 against the plate, one or more arcuate slots or openings 21 are formed in said plate to receive fasteners, such as screws or bolts 22 extending transversely through said member and having wing nuts or lugs 23 threaded thereon.

- The member 24 is substantially triangular and has a straight edge 24 extending laterally and upwardly from the intermediate portion of the corner edge 17 (Figs. 3 and 4) for contacting the pane to scrape or remove excess putty therefrom. In addition, the straight edge 24 functions as a rest or guide for the glazing blade and determines the angle of the exposed surface of the putty to the pane.

Due to the provision of the slots 21, the member may be pivoted or swung outwardly in anare relative to the blade 13 to vary the angular relation of its edge 24 to said blade and its edges 15' and 17. The member fulcr'u'ms upon the corner edge and it may be desirable to provide a shallow groove or recess 25 in the upper surface of the member (Figs. 4 and 5) parallel to and immediately adjacent the plate 1? for receiving the lower edge of said member. By inclining the groove 25' down wardly and outwardly to the lower margin of the corner edge, the edge engages and extends from said lower margin. in use, the corner edge 17 bears against the pane and projects ahead of the member edge 24' to initially contact said pane and cut the putty 16 along the line 18. The transverse edge 15 engages the putty for smoothing the same, while the edge 24 extends ansverseiy of the pane with its entire length substantially in contact therewith. Since the lower blade is identical to the upper blade except for the reversal of its elements, it is manifest that the tool is reversible for use on any side of a pane and in either direction.

It is noted that the glazing tool described hereinbefore represents a preferred or" desirable embodiment of said tool and is subject to variation as shown in my co"-pending application, Serial No. 220,641, filed April 12, 1951. The tool illustrated herein includes an improvement which facilitates use of the tool in the corners of windowpanes as shown in Figs. 1 and 2. A substantially triangular enlargement or projection 26 is provided by laterally extending the longitudinal margin of the blade carrying the corner edge 17, whereby said edge is disposed or projects laterally outward of the remainder of said longitudinal margin. Thus, the remaining longitudinal margin of the blade does not contact and mar the putty 27 and 23 previously applied to the upper and lower edges of the pane, respectively. Due to the provision of the projection 26, the putty may be smoothed and cut in a substantially straight-line movement in the corners as well as along the margins of the pane, whereby it is unnecessary to swing the tool outwardly away from or change its angular relation to said pane upon approaching said corners.

A slight modification is shown in Fig. 6, wherein the inner or lower end of the corner edge 17 is relieved by being cut away or bevelled as shown by the numeral 29. Due to the bevel 2?, the tendency of the corner edge to drag against and pull or burr the putty along the demarcation line 18 is reduced.

Theforegoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
