New Method of Beddins Glass

Application of Pliable Compound by Cornpreased Air Effects Great Saving in Beddingr Glass-Does Better Job

It is generally acknowledged that the bedding of glass in wood sash, prior to applying the glazing compound, or putty, on the finished job, is very advantageous and makes a much better sash. In fact, a properly bedded glass eliminates any leakage around the glass even though the glazing material should become loose.

In the past it has been the general practice to apply a coat of putty, by hand, either on the edge of the glass or on the sash and then drop the glass into position. And, this method is acknowledged as very slow, and naturally prevents the securing of an even distribution of the putty. The reason that a non-drying compound has not been used for bedding in the past, by the hand method, is that the viscosity or "stickiness" of the material is such that it could not be practicably applied by hand.

For a number of years we have manufactured Nu-Calk calking compound that has been used in great volume and with much success throughout the entire United States. And, all along, I have been conscious of the fact that if it were possible to set glass in a compound having the same essential features as our calking compound, it would create "the perfect job," because it stands to reason that if calking compound IS superior for closing space between window and door frames and walls, it most certainly is superior for the bedding of glass.

As a result of our experiments and tests we perfected a special type air pressure gun, known to the trade as "SPEE-D" bedding gun, which is used in connection with our SPEE-D Bedding Compound. This compound has the same characteristics as our Nu-Calk calking compound. However, it is made to a consistency to work properly in an air gun.

This equipment provides the first practical and efficient method of bedding glass with a pliable compound by mechanical means, and affords the user a saving of 75o/o labor. Also it provides the means of assuring an even, uniform seat for the glass around the entire glass. Flow of the compound is regulated so that there is no exposed compound to clean from glass after it is dropped into position. This is a most desirable and important feature in the production of clean, trim sash.

SPEE-D Bedding Compound and equipment is already being successfully used by a number of sash manufacturers. Among the selling features they are able to point out for their product is that the natural expansion and shrinkage of wood sash is compensated for by bedding the sash with SPEE-D Compound and glazing with Nu-Glaze, both of which set to a rubber-like consistency

The SPEE-D Bedding Compound load (patented) consists of scored collapsible tube filled with SPEE-D Compound. It is closed at each end with patented disc. Each load is in protective paper-board can. To use, remove lid of can, drop load into gun barrel, replace gun cap with nozzle. When load is used, remove gun cap and take out collapsed tube of used load. Gun is always clean. inside and outside.
