GLAZIER S POINT Filed Aug. 14, 1931 INVENTOR: l W 2 2% A TTORNE Y J. 1. ROUTLEDGE 1,828,341

Patented Oct. 2Q, 1931 UNITED STATES PATENT OFFICE JOHN I. nouzrnnnen, or nr'rnrox, ONTARIO, CANADA GLAZIERS POINT Application filed August 14, 1931. Serial No. 557,062.

This, invention is an improved glaziers point.

One object is to provide a glaziers point which may be quickly handled and located 5 in position and inserted in the sash.

Another object is to provide a glaziers point which may be inserted with only the putty knife which is used for puttying in Another object is to provide a glaziers point having a shoulder thereupon so spaced as to automatically indicate to the workman when the point is driven home.

Another object is to provide a form of glaziers point having its rear lateral margins arranged inwardly soas to resist any tendency to work out backwardly through the putty after insertion.

With these and such other objects and advantages as may appear, attention is called to thefollowing specification and to the accompanying drawings as constituting a part so thereof, and wherein Figure 1 is an elevation of a putty knife having mounted thereupon a glaziers point made in accordance with my invention;

Figure 2 is a view in plan showing the method of cutting the points from sheet metal with very little waste of material;

Figure 3 is a plan view of a point;

Figure 4 is an edge view.

The invention comprises a blank of sheet metal formed to embody a forwardly positioned, tapered entering point 1, laterally aligned stop edges or shoulders 2 back of 2, and the lateral margins 5 are tapered convergingly towards the rear.

In use the point is quickly mounted upon the putty knife 6 byv merely slipping the prongs 3 over as shown in turned forwa the front margin of the knife Figure 1, the prongs being rdly. he point may then be quickly and easily forced into the sash over the glass pane (not shown). The distance between the edges 2 and 4 is slightly less than the width of the putty head or ledge (not shown) of the sash. The tapering lateral margins 5 act to prevent the retrogressive movement of the point after it is mounted in place and the putty hardens. In Figure 2 is illustrated an economical method of stamping out the points from sheet metal with slight loss of material.

It is thought that tne construction and use of the point will be fully understood from the foregoing description.

, While I have herein described a certain specific manner and method of constructing and assembling the elements of my invention,

it is understo od that I may vary from the same in minor, details, not departing from the spirit of my invention, so as best to construct a practical device for the purpose intended, as defined in the appended claim.

I claim A glaziers point having a forward tapered entering point, laterally aligned stop shoulders immediately back of the entering point, and laterally aligned knife engaging prongs struck up immediately back of the stop shoulders, the rear edge of the point being out OK parallel with the. edges of the aligned stop shouldersand the lateral edges being tapered convergingly from front to back.

In testimon the entering point and a pair of laterally spaced from the blank, one being positioned immediately back of the marginal edge of each stop shoulder at either side of the base line of the entering point 1. The rear edge/4: of

knife engaging prongs 3, struck up the blankis cut off squarely in parallelism with the forward edges of the'stopshoulders y whereof I afiix my signature.

'JOI-IN I. ROUTLEDGE.
