The present invention relates to new and useful improvements in steel roof or span constructions and has for its primary object to provide, in a manner as hereinafter set forth, a structure of this character of novel form whereby a comparatively large area may be covered without the necessity of using intermediate supports, such as posts, pillars, etc.

Another very important object'of the invention is to provide a roof or span construction of the aforementioned character which may be expeditiously erected and taken down without the necessity of using special tools or machinery,

Still another important object of the invention is to provide a roof or span structure of the character described which may be of any desired dimensions. v

Other objects of the invention are to provide a roof or span construction which will be comparatively simple, strong, durable, light in weight and which may be manufactured and erectedat..

low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of an embodiment of the invention. g c

Figure 2 is an elevational view ofanend portion of therooi'.

Figure 3 is a view in vertical sectionv through of the plates. 7

Figure 5 is a cross sectional view through a portion of the roof.

Figure 6 is a detail view in perspective of one of the arch brackets.

Figure 7 is a detail view in perspective of one of the arch segments.

will also be noted that the struts I! are of sufli- Figure 8 is a detail view insperspectlve of one of the arch braces.

Figure 9 is a detail view in elevation of one of the rings for the crossed arch braces.

Figure 10 is a view in side elevation of a portion of another form of he invention.

Referring now to the rawings in detail, it will be seen that thereference numeral l designates including turnbuckles I for tightening.

Rigidly secured at spaced points on the plates 2 are brackets 6. The reference numeral 1 designates generally a plurality of spaced arches of suitable metal which'are mounted on the brackets 6. Each arch 1 comprises a plurality of segments 8 having overlapping end portions rigidly secured together through the medium of bolts 9.

Extending between thearches l are pairs of. crossed braces III. The braces II are provided with eyes II on their ends which'accommodate the bolts 9. Thus, the same bolts which secure the segments I together also secure the braces II to the arches. Rings ll connect the crossed collapsing. The ends of the struts I! are secured to the joints of the arch segments 8. It

cientlength to skip several of the segments I of the archesiL The reference numeral l3 designates roofing mounted on the arches 1. Of course, the roofing it conforms to the curvature of the arches I and, referring to Figure 5 of the drawings, it will be seen that the sections of said roofing are of 'sumcient width to extend between the adja-- cent arches. The roofing sections l3 comprise. overlapping marginal portions 2| which rest on the arches I. The portions 2| are provided with interlocked V portions II which extend adjacent the opposite sides of the arches I. Then, the

roofing is firmly securedto the arches through tliemeciium of J bolts l5. Washers IQ of suitable material "are provided beneath the bolt nuts I! for preventing leiikage around the bolts;

It will thus be seen that a metallic roof or span has been provided of such construction as ,to obviate intermediate supporting pillars, etc.

It will also be observed that-the structure may be expeditiously erected without the use of special equipment. Further, the structure may betaken down if desired and there 'will- .be practically no-- loss of material.

/ inner and outer arches i8 and I9, respectively, 0

a pair of spaced walls. Mounted on the walls I are metallic plates 2 which are secured by anchors 3, Extending between the plates 2 on the walls I In Figure 10 of the drawings'there is illustrated a modification to be used when unusual strength is desired. This modification comprises which are spaced from each. other through the medium of braces 20." In other respects, this; modification issubstantially similar in construction to that form of the invention shown in Figs. 1 to 9, inclusive.

It is believed that the many advantages of a steel roof or span construction in accordance with the present invention will be readily understood and although preferred embodiments are as illustrated and described, it is to be underat their ends, in eyes engaged with the joints of the arch segments, securing elements passing 'through the eyes and the overlapping end portions of the segments for rigidly securing said segments and crossed braces together, and rings connecting the crossed braces at the points where they intersect.

A structure of the class described comprising a plurality of spaced arches, roofing mounted on said'arches, said roofing comprising sections including overlapping marginal portions resting on the arches, said overlapping portions including substantially V-shaped interlocked portions on opposite sides of the arches, and means for anchoring the roofing sections on said arches.
