BUILDING CONSTRUCTION.

Application led March 1,1926. Serial No. 91,544.

The present invention relates to the conj vstruction of buildings and aims generally to improve the roof and its supporting means.

In the accompanying drawings I. have l illustrated as one embodiment of my invention, a greenhouse constructed in yaccordancel therewith, wherein Fig. 1 is a vertical cross-section of a part of a. greenhouse roof at the eaves, showing one form of astragal or sash bar and support therefor arranged -according to my invention.

Figs. 2 and 3 arerdetail sectional views Ataken on the lines 2 2 and 3-3 respec` a a slot 20 in the lug and alining holes in the tively of Fig.y 1, and

Fig. 4 is a perspective view of anastragal supporting lug conformable to` my invention. i

The construction illustrated in the'draw'v ings and to which my invention is adaptable preferably includes spaced metallic columns turn support longitudinal roof supports vor stringers 12 of any suitable shape, as for instance angle bars, as is common in such construction. The stringers 12-support -the spaced astragals or sash bars 13 which in turn supportk the sections or panels o f cover-V ings 14, illustrated hereinaspane's of glass. In constructing greenhouses according to iiiy invention I iind lit preferable to providecontinuous astragals extending from the ridge pole or uppermost Stringer, as

the case may be, tov the sills 15, thereby avoiding the necessity of separate eaves? plates, as is customary in such constructions. According to the present invention the astragals or sash bars .13 are of. channel shape, being preferably of inverted U-` y shaped cross section, and-are formed with laterally projecting side yflanges 16 which support the panels or panes 14.v These bars 13 preferably arefor'med of relatively heavy,

gauge sheet metal, vas fory instance sheetl steel. and are of suicient strength to support the weight of the glass panes7 l yet, thin and resilient enough to permit flexing inwardly of their sides to accommodate elongation of Y the glass panes due to increasesintempera.-

ture. Any suitable means may be employed for holding the glass panes in place upon the astragals 13, for instance' wire clips 17 as` described in my prior Patent No. 1,000,819, granted August 15,1911. A v y l p My invention contemplates the provision of means for so supporting the astragals 13 upon the `stringers 12 so as to permit of slight movementsl of the astragals relatively to/the stringers to accommodate expansion and contraction of the astragal ant panes of glass due to temperature changes. In the illustrated embodiment of the invention, the

astragals are supported upon the stringers 12 by means of supporting members or lugs 18, which'are preferably formed with a neck portion extending within the channel of the astragal and pivotally secured thereto by means of a relatively loose pivotal connection, as for instance a pin 19 passing throughl sions as to permit of movement ofthe astragals relatively to the structural framework ofthe building -in a direction: extending longitudinally of the astragal, but' to pre- .y

" vent movement of the astragals and panes in a direction transversely of their length. The supporting members or lugs 18 are preferably formed with shoulders 21 for engage-V A-ment with an edge of the angle iron or other vstringer12, and are preferably secured to the Stringer 12 by a -single fastening 22 asfor instance a Vrivet or bolt. This construction permits some yielding of the fastening" means while maintaining a secure connection. Preferably the astragals 13 are supported at eachstringer by lugs 18"thus se- -cured thereto, andfby similar lugs secured tov the lowei' sills 1,5, as is clearlyl shown in Fig. 1. l

VWhen the invention is appliedtofroof constructions, the supporting members or lugs 18'are preferably formed with a relatively long and .narrowvneck portion providing a clearance space on each side of the lug yand between the lower edge of theflange f1.6 of the astragal 13 and the'shouldcr' 23 of theV lug.

'l`herebyrelative movement `is ioo allowed for, -and the freejpassagc of drops" of .water which may collect upon the lower face of the astragal yflange due to condensa-- tion or4 slight leaks in the roof permitted. Thus my improved Vconstruction allows thev drops of water to flow ydown the under sides v Yof the flanges 16 to the sidesrof the house; `whereas if dripped at the lugs it would drip at points within the greenhouse'and would soon kill plants which might happen to be Vadaptable to the construction of .houses -or other glazed structures, it is also .highly adaptablezto the construction of other types oit buildings and roofs, the outer `surface' of which may be covered With Vcomparatively largeV panels or coverings. vHence, although I have referredl to such placed thereunder. Furthermore, lthis construction prevents the collection of drops of Water upon the lugs 18 and Stringer l2 which would quickly corrode and thus weaken the structure.

The advantages of my invention are,`its.

ycracking.; of putty which would otherwise cause leaks. Furthermore, the particular vtype ot supporting lug shown 'facilitates the verection and cheapensl-the cost of construetion oit structures et this type.

`Although my invention is particularly greenooverings iii the claims as covering panels or. panes for the sake of simplicity, it is to be undestood that any suitable type of rigid7 or semi-rigid Wall or vroot` covering iscontemplated.

Obviously Vmy invention is not restricted to the details herein shown anddescribed.
