GLASS-SECURING DEVICE.

Specification of Letters Patent.

Patented Oct. 21,1919.

Application filed March 27, 1916. Serial No. 86,824.

Among the objects of my invention are to provide an improved setting by means of which the plate glass may be held securely in place without injury to the glass, to provide in such a setting an improved inner:

glass clamping or supporting member comprising when assembled at the factory a selfcontained unitary member which it is impossible to disassemble or distort'f'rom its intended'shape or purpose by normal handlin or use, and to provide a construction in w ich a saving of material and labor is efiected without impairing its efliciency for the purposes intended.

In the drawings, in which I have shown several embodiments of my invention:

Figure 1 is a vertical cross-section showing the lower edge or base of the plate glass, the window sill and the setting for the plate glass;

Fig. 2 isa section showing the setting for the side and top of the glass;

Fig. 3 is a section on the line 33 of Fig. 1;

Fig. 4 is a plan view of one of the supporting and reinforcing brackets of the inner glass clamping or supporting member;

Fig, 5 is a section on the hue 55 of Fig. 3;

Fig. 6 is a perspective new of a reinforcing and tightening member of the outer molding or clamping member;

Fig. 7 is a cross-sectional view of a different form of inner clamping or supporting member but utilizing the tubular reinforcement or supports; and

Fi 8 is a front view of the said inner ment er.

Fig. 1. The floor of the sill is covered by a strip of sheet mBtal 22, having its inner edge turned up as at 23 against the riser 21. This covering 22 is preferably in the form of a drawn copper molding which extends down over and fits the projecting front edge of the sill-20' as shown, thus presenting an ornamental appearance and protecting the sill from exposure to the weather.

The inner supporting member for the glass comprises a continuous sheet metal strip 24, also preferably a drawn copper molding, having the channel cross-sectional form shown, in which are housed and permanently secured the supporting brackets 25 placed at close intervals, ordinarily every ten inches, throughout the length of the strip. These brackets are formed preferably from heavy sheet or plate copper, stamped 1 'in the form indicated in Figs. 3, 4 and 5,

that is, with the vertical member or base portlon 26 and the horizontal portion 27.

'The endsof the horizontal portion 27 are turned up and over toward the center to form two tubular portions 28. These brackets are then placed in the channel molding strip 24, the horizontal portion 27 and the tubular portions 28 of the bracket being of such dimensions as to extend completely across inside the channel strip andentirely fill it. These portions 28 form tubular supports for the adjacent edge flanges of the channel strip. They also act as tubular spacers or hollow ended spacers between said edge flanges. The metal of the edge flanges 29 and 30 of the channel housing strip 24 is then punched and struck into the. open ends of the tubular portions 28 as shown at 31 and 32. These conical portions 31 and 32 are thus bent in closely over the edges of the brackets of the tubular portions 28 and serve practically as rivets to securely bind the edge flanges 29 and 30' of the channel strip 24 firmly to and in contact with said brackets and also toprevent the said brackets from I being taken out of said strip 24'or from moving longitudinally therein.

While this alone'forms an operative and effective way of preventing any but an intentional loosening of the brackets in said strip, as a further means of insuring the permanency of the desired intimate connection of these parts even against the efforts of those who would intentionally distort and destroy the structure, I prefer to connect these parts by rivets which I cast in tubular portions 28 and which extend through the edge walls 29 and 30 and embrace the projections 31 and 32. In manufacture, I prefer to fill the said tubular portions 28 with molten metal which is forced thereinto through the openings punched in the channel edge walls 29 and 30 under heavypressure so that it completely fills the tubular portions or spacers 28 and in, around and about the conical projections 31 and 32. This metal cools and hardens in place, the tubular portions forming in effect molds for receiving and retaining the metal in place until it cools and hardens. However, the rivets 33 may be cast in the tubular portions 28 in other ways. Any suitable metal may be used which when it hardens forms a solid rivet-like member 33 in which the conical projections 31 and 32 are embedded and securely held against withdrawal. This inner clamping or supporting member of the sash as thus constituted, is secured in position against the riser 21 of the sills by screws 34, (Fig. 1) passing through a suitable aperture 35 (Fig. 3) in the base or vertical portion of each bracket 25. The inside face of the plate glass 35 rests directly against the edge 29 of the channel-like clamping member 24, which member thus forms a solid support for the inside face of the glass. The lower edge of the glass rests on any suitable setting blocks indicated fragmentarily at 36, Fig. 1, there being two such blocks to each glass, one near each vertical edge and located between the adjacent brackets 25.

The outer clamping member 37 comprises a sheet metal molding of the cross-sectional form shown, preferably of drawn copper and extending throughout the length of the edge of the glass to be clamped. It is reinforced at intervals throughout its length opposite the brackets 25 of the inner. member, by the stamped sheet metal members 38 shown more clearly in Fig; 6. This stamped reinforcing member has its upper edge 39 engaging the continuous down-turned flange or lip of the outer molding and the lower face 40 rests on the inturned continuous opposite edge 41 of said molding. The reinforcing member when inserted in the molding also engages the same at the shoulder 42. After these parts have been assembled at the factory, they are secured together by striking up the metal of the base of the molding and the reinforcing member to form the interengaging lugs 43.

One of the functions of this reinforcing member is to enable, this outer molding or clamping member to be brought up snugly against the plate glass to clamp the latter in position against the inner member. For this purpose it is provided with the inwardly extending beveled or cam-like portion 44, the down-turned end of which rests upon and engages the sill covering The bracket 25 is provided with a brass or similar bushing 45 inserted in an aperture in the portion 27 between the tubular portions 28, which bushing is swaged in position in said portion 27. This bushing 45 is internally threaded and adapted to re ceive a screw 46 the lower end of which engages the cam 0r beveled part 44 of the outer clamp. This screw 46 is inserted through a suitable aperture 24 formed in the sheet metal strip 24, through which aperture it may be manipulated by a screw driver in the usual manner. When the parts are in place the turning down of the screw 46 will cause its lower end to engage the bevel 44 of the reinforcing member of the outer strip, drawing the latter inwardly into snug engagement with the outside face of the plate glass.

In order to permit a lighter weight reinforcing member bracket 38 to .be employed, the ends 47 of this member are turned inwardly as shown to form strengthening webs.

The hole 24 in the back strip 24 immediately above the screw 46 may at times permit moisture or water to enter and in order that it may escape, the front or outer edge of the portion 27 of the bracket 25 is notched or curved as at 48, (Fig. 4) so that the water may pass down between said edge and the edge wall 29 of the channel strip 24.

\Vhen the sash is to be installed, the, inner or supporting member 24 is secured to the riser 21. of the sill by the screws 34. The setting blocks 36 are placed in position, and the plate glass is then moved into position on the setting blocks and close up against the edge 29 of the inner member. The outer member 37 is then slipped into position with the beveled or slanting portions 44 of the tightening and reinforcing members 38 extending beneath the glass and under the set screws 46. The screws 46 are then tightened sufliciently to bring the outer member snugly up against the glass and to clamp the glass snugly between said inner and outer members.

The lower edge of the glass is thus clamped with a vise-like grip between said inner and outer members, and is supported firmly on the inside by the solid supporting brackets 25. The innermost edge of the channel strip 24-is preferably curved up wardly as at 49 to prevent moisture of condensation and the like from the glass running back onto the wood sill.

Drainage and ventilation may be afforded in any of the usual Ways. 7

When the sash is used at the sides and top of the glass, the sill covering 22 such as is shown in Fig. 1 is ordinarily not used. A

. simple flat stri of the material such as is shown at 50, ig. 2) can be used,'in which case it need not be bent up at the riser 21 as indicated at 23 in Fig. 1. Or such flat strip 50 may not be used at all. In either event the free end 51 of the base portion 26 of the bracket 25 is bent rearwardly to a distance equal to the thickness of the channel strip 24. Thus when the brackets are screwed to the part of the frame corresponding to the riser 21 of the sill at the sides and top, the member 24: and the corresponding parts of the bracket will assume their normal position with reference to the framework and not be tipped at an angle thereto as would be the case if the ends of the brackets were not turned inwardly at 51 as indicated by the drawing. Besides, this permits the same finishing or housing strip 24 for the brackets 25 to be employed for all four edges of the glass.

While in the foregoing the tubular portions, spacers or molds 28 are formed integrally with the remainder of the bracket, they may be made otherwise and secured in proper relation thereto in any desired manner. Figs. 7 and 8 illustrate an example of the use of independent or non-integral supports, spacers, tubes or molds, though in this instance a bracket for securing the strip to the inner member is not employed. The molding or housing inthis form has its rear lower edge 60 extended somewhat in width to afford room for the securing nails or screws 61 driven at intervals throughout its length to secure the same properly to the inner member. The supporting, spacing or reinforcing tubes or molds 62 corresponding to the tubes or molds 28 in the other figures,

are merely short lengths of tubing out OK at the desired lengths to completely span the distance across the inside of the molding, and thence secured in place as in the first described construction by first punching the material of the edge Walls of the molding into the hollow ends of the tubes, and then preferably filling the same by casting the rivets therein to form a solid structure and bind the said walls to the tubes.

The tubes may be placed at suitable intervals throughout the length of the. mold- 1ng and preferably in pairs corresponding substantially with the similar parts of the brackets in the other form, and these pairs at about the same distance apart as the brackets. I

The outer retaining strip is shown clamped against the outer face of the glass by long screws 63 assin therethrough and into the wood backing, the screws being located opposite the tubes 62 and between the' two tubes forming a pair as described.

From the construction described a considerable saving in copper results since it is not necessary to entirely cover the face of together.

the riser 21, nor to extend the base of the front molding but a short distance to the rear. Also on account of the solid support for the inside of the glass afiorded by the rigid and strong brackets 25, a lighter weight or gage material may be employed for the housing strip. On account of the design and construction of the material in the brackets themselves, they are so firm, solid and strong that they will not yield under any clamping or wind pressure on the lass.

a While I have thus described the specific details of the particular construction shown in the drawing, it will be understood that Various changes may be'made therein without departing from the invention or the intended scope of the appended claims.
