GLAZING' CONSTRUCTION 2 Sheets-Sheet 2 Filed March 28, 1939 M (Mam,

ATTORNEY Patented Feb. 11, 1941 12 Claims.

This invention relates to a building construction and more particularly to a glazing construction,

The invention has for an object to provide a novel and improved glazing construction which may be economically manufactured and erected and in which the individual panels are supported in a novel manner such as to minimize liability of breakage of the panel or distortion of the structure when the latter expands or contracts under varying atmospheric conditions.

A further object of the invention is to rovide a novel and improved double glazing construction which may be economically manufactured and erected and in which the individual panels are supported in a novel manner such as to minimize liability of breakage of the panel or distortion of the structure when the latter expands or contracts under varying atmospheric conditions.

With these general objects in view and such others as may hereinafter appear, the invention consists in the glazing constructions and in the various structures, arrangements and combinations of parts hereinafter described and particularly defined in the claims at the end of this specification.

In the drawings illustrating the preferred embodiment of the invention, Fig. 1 is a front elevation of a sufficient portion of the side wall of a building embodying the present invention to enable it to be understood; Fig. 2 is a crosssection on the line 22 of Fig. 1; showing the invention as embodied in single glazing construction; Fig. 3 is a plan view in cross-section on theline 3-4 of Fig. 2; Fig. 4 is an enlarged detail view in front elevation showing the manner of connecting adjacent glass holding members to permit relative expansion and contraction; Fig. 5 is a perspective view of a detail of construction to be referred to; Fig. 6 is a cross-section similar to Fig. 2, showing the invention as embodied in double glazing construction; Fig. 7 is a plan view in cross-section on the line 'l-l of Fig. 6; Fig. 8 is a perspective view showing the manner of supporting and connecting adjacent glass holding members in the double glazing construction; and Figs. 9, 10 and 11 are perspective views of modified forms of connecting members adapted to permit relative expansion and contraction of the glass holding members.

In general, the invention contemplates a novel glazing construction embodying uprights and horizontally arranged panel supporting members for supporting the glass or other panels. The

panel supporting members are constructed in sections and of a length such that they may be erected to. overlap upon the face of the upright and to provide a space between ends of adjacent sections thereof. Provision is made for mounting the sections of the panel supporting members upon the uprights in a manner such as to facilitate erection and alignment of the component parts of the glazing structure and also in a manner such as to permit movement of said sections with relation to the uprights upon expansion and contraction thereof, thereby minimizing panel breakage and distortion of the structure under varying atmospheric conditions. The invention further contemplates a novel and superior double glazing construction, as will be described.

Referring now to the drawings, the different features of the invention are illustrated in Figs. 1 and 2, as embodied in a single glazing construction and in Figs. 6 and 7 in a double glazing construction. In general, a series of upright fixed supporting members in preferably tubular in cross-section are arranged to support individual panel sections l2 preferably of glass between horizontal supporting members M. The supporting members Hi are connected to the uprights iii in a manner such as to suspend the panel sections thereon and to provide in effect a floating support for the panels l2 to permit relative movement thereof as will be described.

As illustrated in Figs. 1 and 2, each panel section comprises a rectanguiar panel I2, herein shown as being composed of glass, and which is supported along two edges by the members it extending horizontally between the upright members til. Each panel supporting member Hi is provided with grooves lit and i8 upon opposite sides thereof, the outside wall of the upper groove it being shorter than the inside wall 22 for a purpose to be described. I'he members is are arranged in pairs for the reception of the top and bottom edges of a panel l2, with the parallel longitudinal edges of the panel received in the upper groove It of thelower member, and thelcwer groove it of the upper member. The panel l2 and its supporting members it may and preferabiy will be of the same width and less than the distance between center lines of adjacent upright members It to provide a space it between adjacent ends of the sections of the supporting members is and panels if. The sections of the supporting members M are of such len'gth'as to overlap upon the face of the uprights l t as illustrated.

Provision is made for mounting the adjacent sections of the supporting members I4 upon the upright It! in a manner such as to permit move-- ment of the sections under expansion and contraction thereof and, to this end, the panel supporting members I4 are secured to the upright members I5 by connectors 24 arranged to permit such relative movement. 'As illustrated in Fig. 5, each connector 24 is provided with aligned straight portions 26 adapted to be received in a groove 36 provided on the rear face of each panel supporting member I4. An intermediate portion 32 of the connector is bent to extend over a bolt 34 extending through and projecting from the upright member III as shown in Fig. 3 so that each connector 24 transmits to its bolt 34 onehalf the weight of each of a pair of adjacent panels I2 and their lower supporting members I4.

The bolt 34 extends beyond the panel supporting members I4 and a nut 36 cooperating with a rectangular washer 38 serves to clamp the ends of the .members I4 firmly against the vertical face of the associated upright member II].

From the description thus far it will be observed that in each assembled section, as shown in Fig. l, the ends of both members I4, which carry the panel I2, are vertically supported on the upright members It by the bolts 34. This support is such, however, that endwise expansion and contraction of both the panel I2 and the members I4 can take place freely, due to the provision for relative movement which exists between the grooves 30 of the members I4 and the straight portions 26 of each connector 24. Any expansion or contraction which may take place in a vertical direction is compensated for by the fact that the upper edge of each panel I2 only partially fills the lower groove I3 of the upper member I4, providing ample space for movement of the panel I2 in the groove I8. In order to render the junctions between the panel I2 and the supporting members I4 weatherproof, yieldable plastic material 40 may be employed in the grooves I6 and I8.

Thus, each glazed section is, in efiect, floating between four fixed points of support, represented by thebolts 34 at its four corners, with the connectors 24 permitting independent expansion or contraction of the parts of each section without subjecting the structure to bending strains. Furthermore, each individual panel I2 is floating between the grooves I6 and I8 of its horizontal supporting members I4 thereby permitting expansion and contraction of a panel and its supporting members to take place at different rates according to the expansion characteristics of the material of which the parts may be composed. V

In erecting the single glaze construction in a building, the vertical frame members I0 may be erected in spaced relation upon a base member 42 supported on a suitable foundation 44 as shown in Fig. 2. The base member 42 is shown as being in the form of an angle-iron, with its vertical flange 46 of such thickness as to be received in the lower groove I8 of the first course of supporting members I4. The members I4 may then be attached to the vertical member III by means of the connecting members 24, bolts 34, washers 38 and nuts 36. The grooves I6 and I8 of the members I4 may then be provided with a suitable plastic material 40. Strips 48 of any suitable cushioning material, such as asphaltic felt, are then laid against the upright members III, as shown in Figs. 3 and 4, to form a weatherproof joint and a yielding support for the vertical edges of the panel, such Strips extending vertically along the front edges of the upright between the adjacent members I4. The individual panels may now be inserted into the grooves by first introducing the upper edge of the glass or panel member into the deeper groove It a sufiicient distance upwardly so that the lower edge of the panel may clear the shorter front wall 20. The panel is then lowered into the; groove I6 of the lower member I4 as illustrated in Fig 2. When the top course of members I4 has been reached, the upper grooves I6 of these members are engaged by the downwardly extending flange 50 of a top plate 52 in the form of a channel forming part of the supporting structure of the building. The upright members I0 may be secured at their upper ends to the top plate 52 in any suitable manner. Thus, the entire wall structure is sealed along the top and bottom by the flanges 46 and 56, forming an integral part of the base 42 and top plate 52, respectively.

In order to cover the open spaces I5 between the ends of adjacent panels I2 and between the adjacent sections of the supporting members It, each upright frame member ID is provided with a cap 56. As best shown in Fig. 3, each cap 56 is preferably of general U-shape in: cross-section, with flanges 58 engaging the ends of the several pairs of panel supporting members I4 where they overlie the upright frame member l6. Each cap 56 is provided with a plurality of holes 65 for receiving the projecting ends of the bolts 34, and the cap 55 may be securely positioned by knurled nuts 62 cooperating with the ends of the bolts st. When securing a cap 56 in position, suitable felt strips 64 are placed beneath the flanges 58, to fill the spaces between the flanges and the panels I2, as indicated at the broken away portion of a cap in Fig. 4. Each cap 56 is preferably beveled at its extremities, as indicated at 68, It, so as to merge with the top and bottom panel supporting members I4, and a flashing strip I2 may be placed over the upper flange 50 to make a waterproof seal with the upper members I4 and the caps 55.

Referring now to Figs. 9, 10 and 11, as herein shown, various modifications of the connecting member 24 may be employed in the present glazing structure. One modification, as illustrated in Fig. 6 may comprise a connector 14 in the form of a block, provided with spaced wings l5 having the same width as the slots I6 and I8 of the horizontal members I4. The connector I4 may be mounted on the bolt 34 assing through an opening I6 and the wings I5 are arranged to slide in the grooves I6 and I8 of opposed panel supporting members, thus supporting the latter in a manner as to permit endwise expansion or contraction thereof.

Another modification shown in Fig. 10, may comprise a similar block member I8 provided with wing members 86 adapted to slidingly fit into the lower grooves I6 of opposed supporting members I4. Fig. 11 illustrates still another modfication, wherein the wing members 62, 53 may be cylindrical in form, and adapted to extend into the grooves I6 and I8 respectively of adjacent panel supp rting members I4. Each of the herein illustrated and described connecting members are adapted to support adjacent panel supporting members in alignment with each other and to permit of relative endwise expansion and contraction, as will be apparent from consideration of Figs. 6, 10 and 11.

The herein described manner of mounting individual panel sections to form a single glazed wall may also be used with advantage in a double glazing construction, and as herein shown, see Figs. 6, '7 and 8, the exterior wall 84 and the interior wall 86 may comprise duplicate units similar to the single glazed construction shown in Fig. 2. However, in the double glazed construction, a special cross bolt 88 is preferably used, having extended and aligned portions 9|], adapted to fit into the grooves 36 of the adjacent supporting members Ml of the interior wall 86. Thus, the exterior and interior walls are supported upon the same bolts, which extend through the tubular uprights id. In assembling the double glazed structure, the first step is to insert the cross bolts 88 through the uprights is so that the aligned portions 90 come up against the upright l0. Thereafter, the exterior wall '84. is assembled in the same manner as heretofore described in connection with the single glazed structure. During the assembly of the exterior wall, the cross bolts Stare drawn up tight by the nuts 36 against the upright members Ill, and in a position so that the aligned portions. 90 are horizontally disposed at right angles to the upright members. The interior wall 86 is then assembled upon the opposite side of the uprights, using the cross bolts 88 thus secured to suspend the panel supporting members l4 in a manner similar to the connecting members 24. .In some instances, it may be desirable to use the cross bolts as for single glazed construction, such as where a customer may want to erect a second or interior glazed wall at a later date.

The panel supporting members M, which have been herein described as preferably being of the same width as the individual panels l2, may, in some instances, be made of a length corresponding to two or more panels. In such instances, the members l4 may be provided with a hole through which a bolt may extend to secure the members it directly to the intermediate upright 10 and, in operation, expansion or contraction may take place in a lateral drection toward or from either side of the center of the intermediate upright to which the members are secured.

From the description thus far, it will be observed that the improved glazing construction of the present invention may be prefabricated, and the parts are adapted to be economically and readily assembled with minimum labor. Although the invention has been described as embodied in a side wall of a building, it will be understood that the different features thereof may, if found advantageous, be used in the construction of other portions of a building, such as to form interior partitions, or for skylights, roofs, ceiling, etc.

Although the invention has been illustrated and described in connection with a glazing structure, it will be apparent the panels may comprise materials other than glass, such as of cementitious, resinous and other panel forming materials, and as used throughout the claims the term panel is intended to include such equivalent panel materials. The panels may be provided with sound absorbing and heat insulating material attached to the inside surface thereof. The glazing construction is of such design that suitable ventilating ducts may be inserted in place of some of the panels. In practice, various combinations may be developed according to particular requirements, such as opaque panels along the lower portion of the wall and transparent panels in the upper portion with ventilating ducts placed at suitable intervals in the lower and upper sections, as required.

While the preferred embodiments of the invention have been herein illustrated and described, it

will be understood that the invention may be embodied in other forms within the scope of the following claims.
