10 Claims. (Cl. 189-78) The present invention is concerned with a novel form of division bar such as is used to connect and provide support for adjacent edges of glass plates. These bars may be disposed either horizontally or vertically depending upon the arrangement of the glass plates in any specific structure. In some types of structures the several bars may be disposed both horizontally and vertically.

One object of the invention is to provide a division bar which will provide an even bearing on opposite faces of the glass plates to prevent imposition of external stresses on the glass.

Another object is to provide a division bar of the character described permitting tensioning of the fastening members independently of pressure upon the glass plates.

A further object of the invention is to provide a horizontally disposed division bar of great strength which is self-clearing as to moisture.

In the drawings forming part of this disclosure Fig. 1 shows a fragmentary view of two vertically spaced glass plates connected by a horizontally disposed division bar; Fig. 2 shows a similar view of two horizontally spaced glass plates joined by a vertically disposed division bar; Fig. 3 shows an enlarged cross-section taken on lines 33 of Fig. 1; Fig. 4 shows an enlarged cross-section taken on lines 44 of Fig. 2; Fig. 5 is a perspective View of one form of anchor member for the division bars of Figs. 3 and 4, with a cover member in exploded position for best illustrating the details of assembly of the division bars; and Figs. 6 and 7 show enlarged cross-sectional views of modified forms of the division bars.

The horizontally disposed division bars, particularly those connecting large glass plates, are preferably of heavier construction than those connecting smaller glass plates either vertically or horizontally spaced. It is to be understood however that the division bars of both Figs. 1 and 2 may be used either horizontally or vertically according to the requirements of the particular structure of which they form a part. Horizontally disposed division bars provide vertical and transverse support for the uppermost of the two connected plates whereas vertically disposed bars carry no portion of the weight of the glass plates and provide support for the plates against a force normal to the plane of the plates.

The division bars of Figs. 1 to 4 are comprised of a face member normally disposed on the exterior faces of the glass plates, a backing member engaging the opposite faces of the glass plates, adjustable members connecting the face and backing members and a snap on cover member enclosing the backing member. Such division bars present a smooth exterior surface free of projections and of substantially the same contour on opposite faces of the plates.

Referring now to Figs. 1 and 3, the U-shaped face member 1 includes a web 2, arms 3 extending from the web 2 and re-entrant flanges 4 on the arms 3 in engage ment with the front faces of the

glass plates

5 and 6. Disposed within the face member 1, as shown in Fig. 3 are a plurality of longitudinally spaced lug members 7.

These lugs 7 may be secured in place by any suitable means. As shown in Fig. 3 the flanges 4 of member 1 are inturned to provide for a sliding movement of the lugs. The lug 7 may be of any suitable construction, preferably such that any load on the lug is equally distributed upon the flanges 4. The lug 7 should have some resiliency to absorb the unequal pressures applied by the screw threaded fastening member connecting lugs 7 with the backing member.

The backing member 8 is of generally U-shape having a web portion 9 and arms 10. The mid-portion of the web 9 adjacent the glass plates is offset so as to present flanges 9 for engaging the glass in substantial alignment with the flanges 4 of the face member. A pair of spaced flanges 11 extend from the backing member web 9 to overlap the adjacent edges of the glass plates. The face lugs member 7 and backing member web 9 have aligned openings through which screw threaded members 12 are passed to secure the lugs and backing member in engagement with the glass plates. At the juncture of the backing member flanges 9 and arms 10 suitable indentations are provided to receive the free ends of a cover member 13 providing a snap fit. For purposes of symmetry the outer contour of the cover 13 and face 1 are similar. The cover 13 is retained in position by the flanges 14 ex tending outwardly from backing member arms 10 and in substantial engagement with the arms 15 of the cover 13.

Where desired the backing member may be reinforced by inserting a member 16 between the arms 10 and upon the web 9. A screw threaded member 17, of suitable length, replaces the screw threaded member 12 and securely connects the face member lug 7, backing member web 9 and reinforcing member 16. Preferably, when the division bar is horizontally disposed, the backing mem ber flange 11 is extended beyond the lower edge of the glass plate 5 to deflect moisture passing into the face member 1. The lower arm 3 of the member 1 has suitable weep holes 18 permitting the moisture to escape.

Referring now to Figs. 2 and 4 of the drawings, the division bar therein disclosed is of lighter construction but of similar design to that shown in Figs. 1 and 3. The channel shaped face member 19 has a web 20, flanges 21 and re-entrant flanges 22 engaging the front face of

glass plates

5 and 6 Within the face member are a plurality of longitudinally spaced lug members 23 which preferably are of at least some resiliency. The backing member 24 has a web portion 25 and rearwardly extending arms 26. The mid-portion of web 25 being inwardly offset to provide flange portions 27 which engage the rear faces of the

glass plates

5 and 6 in substantial alignment with the re-entrant flanges 22 of face member 1. The

flanges

22 and 27 engage the faces of the glass plates inwardly of the edges of the plates. Extending outwardly of web 24 of the backing member 25 are flanges 28 which substantially overlap the edges of the plates, as shown. Extending within the aligned apertures in lug member 23 and backing member 24 are screw fastening members 29. Some resiliency in lug members 23 absorb any uneven tensioning of member 29 which may result from variations in the force exerted by the members 29 along the length of the division bar. The snap on cover member 3% at tached to the backing member fully encloses the backing member and screw threaded members. This cover member 30 is preferably of substantially the same contour as the face member 20 giving a symmetrical appearance to the division bar.

Referring now to Fig. 5 of the drawings, there are times when it is desirable or necessary to fasten the division bars of both Figs. 3 and 4 to supports at each end of the bars. A suitable method of fastening the bars is shown in Fig. 5 wherein fastening members, such as angle clips 31 are secured to the backing member 24 and plane.

to a support such as a floor, ceiling or wall by suitable means such as screws 32. The cover member, shown in exploded relation to backing member 24, has suitable notches 33 forfltting over. the angle clips 31.

.6 and 7', where the division bar is similarin construction to that shown on Fig. 4 excepting for the face plate.

In Fig. 6'the face plate 35 has

web portions

36 and 37, flanges 38 and re-entrant flanges'39 engaging the glass plates 5b and 6b. Within the face plate 35 are a p'lurality of lug members 40. The backing member .41,comfprises a web portion 42 and forwardly extending flanges .43 which engage theglass sheets b and 6b. Within the web 42 and lug 40 arealigned apertures for receiving screw fastening members 44 which secure the face plate with flanges 54 which terminate in re-entrant flanges 55 Lug members 56 engaging the glass plates 5c and 6c. are disposed within the face plate and provided with portions 56 for positioning the members 56 longitudinally of the face plate 51. The backing member 57 is similar .to that of Fig. 4 excepting that the web terminates in flanges 27 which are deflected forwardly tolie in the plane of and engage the glass plates 5c and 6c. The arms 26 provide for snap engagement of a cover member as in Fig. 4. Disposed within aligned apertures .of backing member web 25 and lug member 56-are The materials used and methods employed to form the various members of the division bar may vary to suit design requirements. The 'face members and snap on covers may be of aluminum, copper, stainless steel or other suitable materials shaped on forming rolls. members may be of similar materials and preferably extruded to shape. The face member lugs are preferably of tempered metal to provide rigidity with controlled rcsilience so as to best serve their intended function. The backing member stiffening insert, as in Fig. 3, may be of metal tubing or of other suitable forms. The screw fastening members are preferably supplied with shoulder portions swage locked into the face member lugs for ease of assembly.

The various forms of construction shown or suggested are primarily for purposes of illustration and not by way of limitation, except as made necessary by the appended claims.
