1964 R. MIGNEAULT ETAL GLAZING STRIP AND ARTICLE EMBODYING SAME Filed Feb. 11, 1963 VENTOR PATENT AGENT United States Patent 3,144,689 GLAZING STRIP AND ARTICLE EMBODYKNG SAME Romuald Migneault and Fenland W. Migneault, both of 332 St. Andre St, Gatineau, Quebec, Canada Filed Feb. 11, 1963, Ser. No. 257,642 1 Claim. (Cl. 20-564) This invention relates to glazing strips for use in glazing wood sashes and the like.

The use of plastic composition glazing strips in conducting glazing operations in metal frames and sashes is widespread. However, the common and universal manner of glazing glass panels in conventional wood sashes and frames involves the use of putty and the like and no satisfactory preformed glazing strip for glazing wood sashes appears to have heretofore been provided.

It is an object of this invention to provide a preformed glazing strip for use in glazing wood sashes, such strip being of simple and convenient manufacture, easy and rapid to install Without special skill, and fully effective in providing adequate sealing and position-retaining contact with its glass and wood engaging surfaces.

Another object is to provide a glazed wood sash having a preformed glazing strip incorporated therein without use of separate fastening elements.

The invention will be described with reference to the accompanying drawing, in which FIGURE 1 is a perspective view of a glazing strip in accordance with the invention,

FIGURE 2 is a partial elevational view of a glazed sash in accordance with the invention, and

FIGURE 3 is a section on line 33 of FIGURE 2.

The glazing strip in accordance with the invention is preferably produced by extrusion from a plastic composition material. The plastic composition material may be polyvinyl chloride, polyethylene, or the like. Preferably, it is of soft, pliable, rubber-like form.

The strip 10 may be about /1 inch in width with an overall thickness of about A inch, and this dimension will usually be satisfactory for most glazing operations. The strip is of uniform cross-section and has a main body portion 11 which gradually increases in thickness from a substantially sharp longitudinal forward edge 12. Portion 11 has a slightly convex outside surface 13 and a slightly concave inside surface 14. Body portion 11 is thus generally triangular in cross-section. Surface 13 terminates in a rearwardly directed lip 15 which constitutes a portion of a shoulder 16. A base portion 17 extends rearwardly from shoulder 16 adjoining surface 14. Base portion 17 has two pairs of opposed barbs 18 directed forwardly towards forward edge 12. It will be apparent that two of the barbs are in opposed relation to shoulder 16 and the other two project outwardly from surface 14.

Referring to FIGURES 2 and 3, the glazing strip described is employed to glaze a wood sash 19 with glass panel 20. The sash 19 comprises sections 21 each having the usual glass panel seating shoulder 22. Each sash section also has a groove 23 in parallel relation to shoulder 22 and in the contiguous sash surface 26 perpendicular to the shoulder. Each groove is of rectangular crosssection and is defined by opposed side walls 24 and a bottom wall 25. One side wall 24 is disposed substantially in the plane of the outer surface of glass panel 20.


While the groove may have any suitable dimensions, it has been found that one Ma inch wide and inch deep is quite satisfactory.

The glazing strip 10 is applied by cutting appropriate lengths thereof and inserting the base portions 17 into the grooves 23, the joints being mitred as shown. Surface 14 of each strip length, by reason of the fact that it is initially bowed or concave and because the wall 24 of groove 23 is in the same plane as the glass surface, will be constrained to flatten out and sealingly engage such glass surface. The edge 12 is in particularly snug contact with the glass surface to eliminate possibility of any leakage therepast.

It will be apparent that the barbed base portion 17 has a rearward extent substantially equal to the depth of groove 23 whereby shoulder 16 engages the sash surface 26. As shown, shoulder 16 flattens against such surface and, since lip 15 initially projects rearwardly, it will snugly and sealingly engage the surface 26 to prevent any leakage therepast.

Insertion of the barbed base portion 17 into groove 23 is designed to compress the barbs 18 thereof as shown in FIGURE 3. The undistorted overall thickness of the portion 17 may be about one-sixteenth inch greater than the width of groove 23 to provide the required compres-v sion of the barbs. The base portion 17 holds the glazing strip in position but permits removal thereof in the event that reglazing is necessary.

Glazed sashes, as described, have been found to be fully as effective as conventional putty-glazed sash in actual use. Indeed, the life of sashes glazed in accordance with the invention is much longer since, of course, putty glazing deteriorates with age.

Probably the most important advantage of the invention resides in the fact that glazing in accordance therewith may not only be carried out by unskilled labor but the time required to effect the operation is significantly reduced with consequent substantial saving in labor costs. The replacement of broken glass panels is also greatly facilitated by use of the glazing strips described.

We claim:

A glazing member comprising an elongated, pliable, un tary strip of plastic composition, said strip being of uniform cross-section throughout its extent, said strip having a forward body portion and a rearward base portion, said body portion having a convex outer surface and a concave inner surface, said surfaces converging towards each other and terminating in a common longitudmal edge of said strip, said strip also having a longitudinally extending shoulder at the juncture of said body and base portions and offset from said juncture, said shoulder having a transversely concave surface having a terminating edge defined by its line of juncture with said convex surface of said body portion, said base portion having compressible barbs projecting from each side thereof, said barbs on one side of said base portion being 1n opposed relation to said shoulder.
