GLASS CLIPS Filed July 24, 1952 2 Sheets-Sheet 2 I N VENTOR Arno/d A. Zach mam BY BMW L31? ORNEY United States Patent GLASS CLIPS Arnold A. Zachman, St. Paul, Minn.

Application July 24, 1952, Serial No. 300,599

9 Claims. (Cl. 189-78) lapping relation. The panes are usually supported on an inclined plane and the upper edge of the lowermost pane lies beneath the lower edge of the next adjacent pane. In other words, the glass panels are usually overlapped similarly to shingles so that moisture will not leak therethrough.

An object of the present invention lies in the provision of a clip which is designed to support the glass panes in proper overlapping relationship. These clips are designed to assist the sealing composition in holding the panes in place.

An object of the present invention lies in the provision of a resilient clip which cooperates with a glazing bar of inverted T-shape or of L-shaped form. "The glazing bar is provided with an undercut shoulder near its upper extremity running throughout its length. The glass clips are designed to engage the lower edge of the upper pane and the upper edge of the lower pane and to resiliently engage the undercut shoulder so as to firmly hold the panes in position.

An added feature of the present invention lies in the fact that the clip may be constructed to engage the lower edge of the uppermost pane only, if desired. Such a clip prevents the uppermost pane from sliding downwardly and obviously is more necessary than a means for holding the lower pane from sliding upwardly. A clip of this type may be more easily removed in the event of broken glass and has some advantages in certain installations.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

In the drawings forming a part of the specification:

Figure l is a perspective view of a pair of overlapping glass panes showing my clip used in conjunction therewith.

Figure 2 is a perspective view of the clip illustrated in Figure 1.

Figure 3 is a perspective view similar to Figure i showing the modified or simplified form of clip.

Figure 4 is a perspective view of the clip illustrated in Figure 3. g p

The glass panes employed in many types of green house structures are held in overlapping relation upon glazing bars which extend angularly toward the ridge pole of the green house. Figure 1 illustrates a glazing bar 10 which is of inverted T-shaped formation including a central upright flange 11 and a pair of laterally extending coplanar flanges 12 and 13 at its lower extremity. The upper edge of the vertical flange 11 is provided with an enlargement 14 projecting beyond either side surface of the vertical flange 11 and provided with an undercut 'ice shoulder between each side of the enlargement and the flange 11. One such undercut shoulder 15 is visible on the exposed side of the flange 11, while another similar undercut shoulder 16 is provided on the opposite side of the flange.

Two glass panes are illustrated in overlapping relation. The lower pane 17 rests upon the flange 12 and is supported thereby. Putty or some other sealing compound is placed upon the flange 12 beneath the pane 17 so as to form a seal between the flange and the glass. In actual practice the lower edge of the pane 17 overlies and overlaps the upper marginal edge of the next lower pane, not illustrated in the drawings. a

Figure 1 illustrates only one side edge of the panes, it being understood that the panes are generally rectangular in form and are supported between two parallel glazing bars. The uppermost pane illustrated is indicated at 19. It will be noted that the lower marginal edge 20 of the upper pane 19 overlaps the upper marginal edge 21 of the lower edge 17. The overlapping of the panes does not provide an air space between the panes and the flanges of the glazing bar in view of the putty beneath the glass.

The clip is indicated in general by the letter A. This clip includes a vertically extending portion 22 which is designed to extend into the undercut shoulder 15 and be resiliently engaged thereby. The portion 22 is bent at 23 to form an inclined portion 24 which in use inclines away from the glazing bar. At its lower end, the inclined portion 24 is bent at 25 to provide a bearing portion 26 which is parallel to the surface of the glass pane 19 and is in surface contact therewith. The bearing portion 26 is provided with a down-turned flange 27 along one edge thereof, the flange 27 being designed to engage against the edge 20 of the upper pane 19.

In order that the clip may be formed of a strip of metal of substantially equal width throughout, the bearing portion 26 does not extend the full width of the strip, the flange 27 being formed by striking downwardly a portion of what would otherwise comprise a part of the bearing portion. At the edge of the bearing portion opposite to the bent edge 25, the metal strip is bent downwardly to form a vertical panel 29 which is substantially aligned with and on the same plane as the upper portion 22. The vertical portion 29 connects the bearing portion 26 with a bottom portion 3 which is designed to underlie the lowermost pane 17. A flange 31 is struck upwardly from a side edge of the bottom 35 the flange 31 being designed to extend along the upper edge 21 of the lower panel 17. In order that the clip be made of material of substantially equal width throughout, the flange 31 is struck out of the portion which would otherwise comprise a part of the bottom 39, the bottom 34) thus becoming narrower than most of the remainder of the strip.

It will be seen that the striking of the flanges 27 and 31 from the panels to which they are attached serves the double purpose of conserving material and of allowing the overlap between the panes to be maintained at a minimum. The upper inclined portion 24 and top retaining portion 22 of the clip may extend the desired width without necessitating an excessive overlap between the panes. v

In applying the clip the bottom 30 is usually inserted beneath the upper edge of the lower pane 17 with the vertical portion 29 extending in substantial surface contact with the glazing bar flange 11. The upper pane 19 may then be moved downwardly until the lower edge 29 thereof engages against the flap 27. This is done while the upper end of the clip is free of the shoulder 15. The inclined portion 24 of the clip is next pressed inwardly, the structure flexing suficiently to engage the upper edge of the vertical portion 22 in the shoulder 15 under slight tension. The tension is normally sufficient to prevent naovement of the clips longitudinally of the glazing bar. Howeverpin any event the flange 31 which engages the upper edge of the lower pane holds the upper pane from moving downwardly so-thatithe tendenc-yfor theclip to :move'longitudinally isiat a minimum. figure 1 of the adrawingsrshowsithe clip A as employed onvthepanesoverlying theflangeJZ'. Figural indicates the same clip in reversed form showing the construction as it would be employed onthe opposite flange 13.

Ill-Figured of the drawings Idisclose-a-rnodified form of clip which isindicated in generalby the letter C. The clip-C is virtually identical with the previously described clip A with the exception of thellower-partof theclip A which-has been-omitted. The clip -.C. includes. an upright :flange 32 which :is connected alongaline .of bendfili 'with an inclined portion 34. The lower'endof the inclined portion-34 h connected along the line of bend 35 to the bearing-portion 36 designed torest' in surface contact *with-thepane-l9; :The bearing portion 36 is provided with a vertical, portion 37 extending downwardly. in substantially the planeof the vertical portion 32. This flange 37- extends-alongthe marginalusideedge of the glass, pane l9 in-surfacecontact with the flange-11 .of the :glazing bar 3.0. V

A portion of the bearingportion 36iscutawayand bent downwardlyto-provide a shoulder 39. T his shoulder extends along the lower edge of the pane-19m hold the pane from sliding downwardly.

The clip C thus: acts to' hold the pane 19 in place. and

Y dueto its'resilient-engagement withthe -shoulder-.15 it keeps the pane from sliding downwardly. Theiclip C is not-as positive in its action as theciip A, butis de- 'sirable for use insome instances. For'example if-i6f- 1 tain of the panes become broken, the clip C maybe more readily removed. The clip C is also useful as a replacernent unit for the-clip A after a pane of glass has been removed.
