Specification of Letters Patent.

Patented oct. 24, 1911.

Application filed March 27, 1911. Serial No. 617,184.

To all whom it may concern: Be it known that we, OLE K. SIMoNsnN and CARL RASMUSSEN, citizens of the United States of America, andresidents of Chicago, county of Cook, State of Illinois,-have invented certain new and useful Improvements in Glass Ceiling Constructions, of which the following is a specification.

The main object-s of this invention are to provide an improved construction for glass ceilings; to provide an improved form of fastening device particularly adapted for securing the panels of glass ceilings and adapted to be secured to the supporting structure in such manner as to be capable of being attached to said supporting structure previous to the attachment of the panels thereto and adapted to be shifted so as to allow the panels to be afterward inserted; and to provide a fastening device of this kind which will space apart the edges of the glass panels and prevent the same from shifting and thereby avoid chipping of the edges or cracking of the panels through contact with the nails or screws by means of which the finishing beading is attached.

An illustrative construction embodying this invention is shown in the accompanying drawings, in which Figure 1 is a fragmentary bottom plan of a glass ceiling constructed according to this invention. Fig. 2 is a sectional detail of the same taken on the line AA of Fig. 1. Fig. 3 is an enlarged fragmentary detail in plan, showing the method of fastening the panels at their corners. Fig. 4 is a section taken along the line BB of Fig. 3. Fig. 5 is a transverse section on the line CC of Fig. 2. Fig. 6 is a detail in perspective of the fastening device.

In the form shown in the drawings, the ceiling is made up of a plurality of panels 1 of glass or other suitable material secured to a supporting structure 2, which may be built up of intersecting bars extending along the joints between the panels. The adjacent edges of contiguous panels are spaced apart slightly and the adjacent corners of the panels are fastened by means of fastening disks or plates 3 which are of suitable contour to overlap the adjoining panels so as to secure them against the sup porting structure 2. These plates 3 are preferably made of sheet metal stamped to a form similar to that shown in Fig. 6, so as to provide ribs .or shoulders A adapted to extend into the spaces between the adjacent edges of the panels and abut against said edges so as to prevent the panels from shifting after the plates 3 are in position. The outer faces of the plates 3 are provided with grooves 5 along the ribs i, and the plates 3 are fastened to the supporting structure 2 by means of rods-6 which extend along one of the grooves 5 and are provided at their ends with fastening means, here shown as prongs 7, which are driven into the supporting structure 2 so as to hold the plates 3 against it, but allow them to be shifted along the rods 6. Each of the plates 3 also preferably has a tongue 8 struck up from its material at its middle part and curled over so as to encircle the rod 6 and secure the plate to it.

In assembling the ceiling, the fastening plates 3 with their rods 6 are fastened to the supporting structure at approximately the points where the corners of adjacent panels will meet. Then when the panels are being placed in position, the plates 3 may be shifted along the rods so as to allow the panels to be seated against the supporting structure, and are then shifted back so as to properly engage and secure the corners of the panels. After the panels are in position, strips of beading 9 are secured along the edges of the panels so as to cover the spaces between them. The strips 9 may be fastened by nails or small screws in the usual manner, as illustrated in Fig. 5. After the strips 9 are in position, ornamental rosettes 10 are secured over the plates 3, and these are preferably recessed, as will. appear from Fig. 2, to receive and cover the ends of the strips 9. Each rosette is then finally fastened by a single screw 11 extending centrally through it and through the central aperture 12 in the corresponding plate 3. It will thus be seen that the shoulders 4 on the plates 3 confine the corners of the panels in such manner as to prevent any shifting thereof after the rosettes are in place and although the plates 3 are readily shiftable to permit the convenient insertion of the panels during the operation of assembling the ceiling, they are prevented from shifting in any manner by the screws 11 after the rosettes are in position.

Although but one specific embodiment of this invention is herein shown and described, it will be understood that numerous of adjacent panels and having on one face a projection adapted to space the panels apart, and a'rod extending along'the space between the panels, being 'slid'ably connected with said plate and provided with attaching means at its ends spaced apart to permit said plate to slide along said rod so as to facilitate the insertion of the panels behind said plate.

2. A panel fastening device, comprising a plate having intersecting ribs formed on one face and having a channel in its opposite face a'long one of said ribs, a rod connected tos'aid plate and slidable lengthwise in said channel, said rod being provided with fastening means located 'so as to permit said plate to be slid along said rod.

3. Apanel fastening device, comprising a sheet metal platefbe'ntto provide intersecting ribs on one face thereof and channels on the reverse face, a rod extending along one o'f said'channels and provided with fastening means at its ends, and means connecting said rod and plate and adapted to permitsaid plate to'slide along said rod.

4. A panel fastening device, comprising a sheet'nietal platebent to provide intersecting ribs on one face thereof and channels on the reverse face, a rod'extending along one of said channels and provided with fastening means at its ends, and a fastening tongue struck up from said plate and encircling said rod for slidably connecting said rod and plate. v

5. A panel fastening device comprising a plate having intersecting ribs formed on one face and having a channel in its opposite face along one of said'ribs, a -rod connected to said plate and slidable lengthwise in said channel, said rod being provided'with transverse prongs located'so as to; permit said plate to he slid along saidrod.

6. In a ceiling construction, the combination of'a supporting Structure, a plurality of panels mounted on said supporting structure, rods secured to said supporting structure and extending along the spaces between adj acent panels at the corners thereof, fastening plates slidably mounted on said rods, being shaped to overlap the faces of adjacent panels and having shoulders adapted to enter the spaces between said panels for spacing them apart, strips extending along and covering the spaces between adjacent edges of said panels, rosettes secured over said plates and covering the adjacent ends of said strips, and fastening means extending from said rosettes through the respective plates and adapted to secure said plates against shifting on said rods.

7. In a glass ceiling construction, the combination of a supporting structure, a plurality of panels adjacent to one face of said structure and having their adjacent edges spaced apart, a plurality of fastening rods secured to said supporting structure in the spaces between the edges of said panels, fastening devices slidably mounted on said rods and adapted to overlap adjacent corners of said panels for securing the same to said supporting structure, strips extending along and covering the spaces between said panels, rosettes mounted to cover said plates, and fastening means extending from said rosettes through said plates and'adapted to secure said plates against shifting on said rods, said platesbeing'provided with shoulders'adapted to engage and space apart the adjacent edges of said panels.

'8. A panel fastening device, coniprising a plate adapted to overlap the adjoining corners of adjacent panels and having thereon means for spacing the edges of the panels apart, and securing means for attaching said plate to a supporting structure and having movable engagement with said plate adapted to permit said plate to be shifted edgewise after its attachment to such supporting structure to permit the insertion of the panels behind said plate.
