3 Claims.

The principal object of this invention is to provide a generally improved glaziers tool combining in a single instrument the functions of a setter for glaziers points and a putty knife.

The tool contemplates utilization of the physical characteristics of a putty knife blade to steady the tool in the point-applying operation, and to this end the tool comprises a handle element designed to comfortably fit the palm of the hand and having aligned terminal portions which function jointly to provide a stable rest for the tool against the surface of a pane of glass or other workpiece, one of said end portions having a point-driving abutment substantially in the plane of said Work surface and the other end portion having a blade element, constituting the putty knife component, associated therewith in a manner such that it may act to support the tool in proper position during the operation of setting or driving the said points and also to distribute the thrust of the tool against the glass or other work surface. The handle element is of a character to facilitate manipulation of the tool in both of the aforesaid primary functions. The principle of the invention will be more readily understood by reference to the attached drawings, wherein:

Fig. 1 is a side elevational view of a tool made in accordance with the invention;

Fig. 2 is a top plan View of the tool;

Fig. 3 is a View in perspective illustrating the mode of operation of the tool in the point-setting operation and the manner in which the putty knife component in this operation affords essential lateral stability to the tool as well `as functioning to distribute the pressure forces applied through the tool to the glass over a relatively extended surface area of the latter;

Fig. 4 is a fragmentary view in perspective illustrating the manner in which the tool is manipulated in the putty knife function, and

Fig. 5 is a view in perspectiveof a conventional form of glaziers point to which the tool is adapted.

With reference to the drawings, the tool in a preferred form comprises a bowed handle element I having offset end portions 2 and 3, respectively. As shown in Figs. 1 and 2, the handle element, in the present instance, is of strap metal of adequate strength and rigidity and the end portions 2 and 3 are aligned with each other with respect to the longitudinal axis of the tool. By reason of this alignment the end portions 2 and 3 are adapted to constitute, in effect, a stable rest fOr @he tool .in a normal opera'fve position against a Work surface (indicated in Fig. 1 by the reference numeral 4) such for example as a pane of glass.

The terminal portion 2 is rabbeted at its under surface and inwardly from the extremity thereof as indicated at 5 in Fig. 1, the depth of this recess from said under surface being substantially that of or slightly less than the thickness of the conventional glaziers point of the type shown in Fig. 5 and indicated by the reference numeral 6. To the under side of the terminal portion 2 is secured, by means for example of Welding, a thin leaf l of spring steel. Preferably this leaf 'l is co-extensive with the under surface of the terminal portion 2, and between the leaf and the .body of the terminal portion the rabbet forms a pocket adapted to receive one straight edge portion of a glaziers point 6, as indicated in broken lines in Figs. 1 and 2, the point by reason of the resilient pressure of the spring 1 being frictionally held within the pocket with the aforesaid straight edge in abutment with the inner Wall of the pocket or of the rabbeted recess 5.

To the opposite end portion 3 of the handle I is attached, by Welding or other suitable means, a blade 8 which is of sufficient Width to function for putty knife purposes and which, in the present instance, is substantially wider than the handle I'. It will be noted that when the tool is placed in normal working position against a work surface such as 4, or against the surface of a pane of glass as illustrated in Figs. 1 and 3, the aligned end portions 2 and 3, as previously stated, afford a stable rest for the tool against the Work surface. In this position the glaziers point 6 is held substantially in the plane of the work surface and in edge-abutting relation with the end portion 2; and the blade 8 at the opposite end of the tool bearing flatly against the work surface lends a high degree of lateral stability and guides the tool accurately on the flat surface so that it tends to maintain itself in the normal operative position. The relatively extensive area of the knife element 8 functions also to distribute the pressure of the tool upon the surface of the glass over a relatively wide area of the latter and so avoids concentrated pressure in any localized area of the pane. In this manner the pressure against the glaziers point required to force it home in the window frame 9 (see Figs. 3 and 4) may be effected readily and without hazard to the glass-against which the tool bears in the point-driving operation. It will be noted further that the frictional pressure of the spring 'l upon that portion of the glaziers point which occupies the recess 5, While sucient to retain the point, is relatively light so that after the point is forced into the wood of the window frame or other work and the tool then withdrawn, the point will remain in the work. Still further, it will be noted that in this operation the tool avoids necessity for impact to drive the glaziers point into place and substitutes iinstead pressure `applied. `readily through the itool, the bowed handle being of a shape to permit ready application of the required force to the tool substantially in the direction in which the point is to enter the work. The handle and the positional relation of the blade 8 to the handle also aid materially inzmanipulationzof 'the tool in the putty knife function, yas,illusltra'tedin Fig. 4.

I claim:

1. A glaziers tool comprising a bowed handle element having oiset end portions aligned 'with each other and providing jointly a stable rest for the 'tool against the 'surface'ofra pane of glass or otherworkmembenthe extremity of one of said end portions being adapted for abutting engagement with :a glaz'ierfspointzsoas -to provide for application of pressure to .said point substan- #shoulder on one of said end portions for setting `engagement with a glaziers point, and a blade on 'the other of said end portions forming a relatively `extended zand stable rest for the tool fagainst'the l'surface'of a work member when the tool iis in the -normal point-setting position.
