The rafter from the eave to the column is flat 

 steel, to which the three purlins are bolted 

 and the cypress glazing cap screwed. 



e 83 Feet Wide 



From the column t6 the ridge the rafters are 

 double channel iron, between which the flat 

 rafter is boiled at the point where it is secured 

 to the column. The rafter glazing cap is held 

 firmly by two screws placed at interval up 

 the roof. 



column is secured to tJje eave by a doubl* steel «usset plate. 

 It is stiffened by a truss running from the gusset plate at the 

 tave to the one at the column. From the column to the ridge 

 Ihe rafter is made of two channel irons, between which the 

 flat iron rafter is joined at the I-shaped column by gusset 

 plates. The trussing between the columns and ridge is made 

 of double angle irons. Notice that the truss ties running 

 from the columns to the struts do not go straight across, 

 '^ut slant upward^ practically forming an arch. Every- 

 ''ody knows that an arch is one of the oldest and strongest 

 orms of construction. 



So strongly framed is this house, that if the rafters and 

 side posts on each side of the columns were taken away al- 

 'oeethcr, that part of the house left would be •ntir«ly svlf- 

 ■uttainins. 



As apparently simple as the construction is (now that it 

 s all worked out and before your eyes), nevertheless it took

our engineers considerably over two weeks hard plugging to 

 figure out the stress and strains on all the various parts of 

 the frame, and to know to almost an ounce, exactly what 

 weight of wind or snow pressure would be exerted on the roof 

 at any and all points. 



There is not a bit of guess work in that entire construc- 

 tion. It is all based on facts and figures. Not the figures of 

 some mechanical construction book, compiled by a sky scraper 

 engineer or bridge builder— but the facts and figures accum- 

 ulated and proven in our business of more than half a cen- 

 tury of greenhouse building. 



This 88 footer is a grejit house. A safe and sure 

 house. 



Now where is the progressive grower who wants to talk 

 it over with us? 



Say when and where and we'll be there.
