WINDOW CHANNEL OR THE LIKE Filed Oct. 12, 1936 I A I I I A Patented Jan. 18, 1938 UNITED STATES PATENT OFFICE '1 Claims.
The present invention comprises certain improvements in means for securing plate glass or window glass in place, especially for the purposes of erectingstore or show windows, and the like.
.The construction of the invention is adapted for properly assembling and securing sections of glass in the building of show cases, however, and can be used in difierent places where it is necessary to join two sections or panes of glass together at juxtaposed edges thereof.
' The invention takes the form of a special bar construction for facilitating the uniting or connecting of glass sections or sheets of glass where these members extend from one another at an angle, as for instance at the corner of a showwindow. In addition, the invention makes provision-for special attaching means between sections of glass which lie in the same plane or edge to edge.
Among the objects of the invention are to provide connecting bars of'the type referred to, useful at corner portions of a Window where the glass sections practically meet, and also useful at intermediate sections of glass lying in the same plane, whereby a very solid mounting of theglass members is obtained, and an excellently finished appearance for the completed show or other Window construction secured, with provisions such that the glass members may be assembled on the supporting bar members employed therefor, and clamped to the latter with facility and without liability of breakage of said glass members.
The invention takes different forms, of which several preferred adaptations are illustrated in the accompanying drawing and described hereinafter in detail as to both construction andadvantages.
In the accompanying drawing- Figure 1 is a horizontal sectional view taken through the corner portion of a show or like window and illustrating glass windows or sections assembled or connected by means involving'one preferred form of the invention, and further illustrating one preferred form of connection for glass sections disposed in the same plane, the latter being adapted to be mounted at intervals in the length of the corner connecting means and serving as spacing bars for the corner bars.
Figure ,2 is a sectional View taken approximately on the line 22 of Figure 1.
Figure 3 is a View similar to Figure 1, but-illustrating a slight modification of the construction of the corner or angle bar.
Figure 4 is a sectional view taken approximately on the lined-4 of Figure 2, more clearly bringing out the construction of the spacing attaching bar for glass sections or panes which lie in the same plane when set up.
Figure 5 is a view similar to Figure 1, showing still another modification of the main glazing bar structure in which clamp means are provided to clamp the glass sections in place securely seated against the main glazing bar, without theaid of screws or other similar fastenings.
' Figure 6 is a view similar'to Figure 4, embodying a modification according to the same principles as illustrated in Figure 5. Figure 7 is a perspectiveview of the clam means illustrated in Figures 5 and 6.
Referring first to the construction of my in' vention asembodied in Figure 1, the designation A- denotes the main glazing bar, B the associated clamping bar,,and C the attaching screw means intermediate said bars A and B. The main glazing bar'A is of angular formation and is'designed to be used primarily where the glass sections I and 2 have their edges juxtaposed at acorner of the window or at some portion of the window from which the glass sections l and? extend'from each other at an angle. of a hollow sheet metal body including the outer angular wings 3 and! having the remote edge portions thereof folded inwardly as at 5 and thence extending parallel with the portions 3 and 4 as The bar A is comprised shown at 6 to provide channel portions or seats imately right angles as shown at 1 to provide shoulders at the edges of the adjacent glass sections l and 2. Thereupon, these portions 1 are extended slightly to'bring them together, they being interlocked at such portions by interfolded parts asillustrated at 8. Openings pass through the interfolded parts 8 that unite the edges of the sheet metal that make the bar A, and the screws C are threaded into said openings. Said screws C, as previously indicated, are utilized-to attach the clamping bar B to the main glazing bar A in the space circumscribed by the interior angle between the parts ii of said bar A.
The clamping bar *3 is provided with clamping wing portions 9 that are spaced from and practically parallel with the members 6 of the glazing bar A, and the parts 9 and 6 provide a space or channel between which are received adjacent edges of the glass sections and 2 that are thus heldfirmly in-place seated against and attached together by the parts A and B in the manner set forth.
From the foregoing description it will be understood that the main glazing bar A is preferably of one-piece construction and is composed of sheet material folded longitudinally into generally L- shape in transverse cross section, providing wing portions extending at approximately right angles to each other, forming seats for the edges of the glass sections which are to be secured together, the free margins of the sheet material being brought together at substantially the medial axis of the bar and interlockingly folded around and about each other. The interlocking folded parts of the bar lie intermediate the wing portions and adjacent to the juxtaposed edges of the glass sections, and serve .to support a suitable clamping member or members so as to provide, with the wing portions of the main bar, channels within which the glass sections are adapted to be received. According to the form of clamping member B illustrated in Figure 1, the clamping member is secured in position on the main bar A by a suitable fastening means C, such as a screw, which extends through the clamping member C and into suitable apertures formed in the interlocked folded portions of the main bar A.
The modified construction illustrated in Figure 3 is substantially the same as that illustrated in Figure 1, with the exception that the parts 6 of the main bar A are slightly inclined and are not exactly parallel with the outer faces of the wings 3 and 4. The other parts of the bar A and the clamping member B which are similar to the parts illustrated in Figure 1, are designated by the same reference characters. The purpose of inclining the parts 6" of bar A is to permit the application of putty or other weather sealing means to these parts which form the seats for the glass sections,
' whereby to ensure that the edges of the glass will be sealed against the entrance of dust, moisture, air, and the like. The putty or other sealing medium is designated I0.
Passing now to the construction of the spacing bars which are adapted to secure glass sections lying in substantially the same plane, and referring particularly to Figures 2 and 4, the main glazing bar is generally designated A and this bar is also preferably formed in one piece. The sheet metal body of which the bar is made is folded longitudinally to provide hollow wing portions 3 and 4 extending in substantially opposite directions and being substantially coextensive. The outer margins of the body are folded 'l inwardly as at 5' and 6' to provide seats for the glass sections 22, and the free margins of the sheet of material are brought together and interlockingly folded around and about each other as at 8 in a manner similar to the construction of Figures 1 and 3 above described. The interlockingly folded portions 8' lie substantially at the medial axis of the main bar A and intermediate the ends of the wing portions 3' and 4.
Coacting with the main bar A are one or more clamping members B having wings 9' disposed substantially parallel with the parts 6 of the wings 3' and 4' of the main body A. These clamping members are secured to the interfolded portions 8 of the main bar A by suitable fastening means C such as screws, in the manner previously described, the interfolded parts 8' being provided with suitable apertures therein, and the wings 9 forming, with the wings 3 and 4', channels for receiving the juxtaposed edges of the glass sections 2- 2. In the form of the invention illustrated in Figure 5, the main glazing bar A is substantially the same as illustrated in Figure 1 and is adapted to have associated therewith a clamping member D which is preferably of such construction as to be capable of being releasably at tached to the main bar A without the use of screws or other equivalent fastening means. The form of the member D may be best seen in Figure 7. As illustrated, the member D is composed of resilient sheet material having its marginal edges bent inwardly asat I I and normally disposed in spaced relation to each other for gripping. the interlocking folds 8 of the main bar A. In other words, the distance between the edges IIII of clamping member D is normally somewhat less than the width of the interfolded portions 8 so that when the member D is forced over the folded parts 8, the edges IIII will engage the parts 8 with a firm gripping action, due to the inherent resiliency of the material of the member D. In order to prevent the clamping member D from being disengaged from the interfolded portions 8 too readily and to provide more or less interlocking engagement of the edges II-I I with the portions 8, the folded portions 8 are preferably so arranged as to provide longitudinally extending grooves or depressions I2-I2 at opposite sides thereof. Of course, by the application of suitable force to the clamping member D, the member D may be snapped off or applied to the main glazing bar A, at will. When the clamping member D is mounted on the glazing bar A, the portions I 3| 3 thereof lie in spaced relation to the wing portions 3 and 4 of the main bar A, and form therewith channels for receiving the juxtaposed edges of the glass sections I and 2, and the clamping member D serves to firmly clamp the glass sections on their respective seats of the main glazing bar A.
The construction of Figure 6 is generally similar to that of Figure 4, and illustrates the substitution of a clamping member D like that shown in'Figures 5 and 7, for the clamping member B of Figure 4. The function and manner of applying and removing the clamping member D according to the form illustrated in Figure 6 will be readily understood from the foregoing description and need not be repeated. The parts of the main bar A and clamping bar D similar to those parts illustrated in Figures 4 and Shave been designated by the same reference characters in' Figure 6. It will accordingly be understood that Figure 6 illustrates the manner of clamping the juxtaposed edges of glass sections disposed in the same plane, against the seats provided by the main bar A, without the use of screws or equivalent fastenings of the Figure 4 construction.
In mounting the glass sections in the glazing bars of the various constructions herein disclosed, suitable provision should be preferably made to allow for expansion of the glass sections. To this end, the glass sections may be cut so as to leave a slight space between the extreme edge faces thereof and the main glazing bars A or A, these clearance spaces being designated I4 in each of the views of the drawing.
It will also be understood that in any of the various forms of main glazing bars, the portion 6 or 6' may be inclined as in Figure 3 and desigis not absolutely necessary to do this in every case.
While the specific details have been herein shown and described, the invention is not confined thereto, as changes and alterations may be made without departing from the spirit thereof, as defined by the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:--
