FRAME TRUSS STRUCTURE Filed April 15. 1929 Inventor:

Patented Apr. 14, 1931 mousse CLEMENT L. EWING, OF JEROMESVILLE, OHIO FRAME-TRUSS STRUCTURE Application filed April 15,

my present invention relates to improvements in barn frame truss structures, and particularly of the class described in my application tiled March i l, 1928, Ser. No. i. i-lfiLtE-lfi, allowed July 19, 1928, and its principal oijects similar thereto, namely, to provide barn frame truss suitable for larger buildings than heretofore covered by a single root, and improved means for reentorc- U ing the enlarged curvature of the arch, and to strengthen and stiffen the posts of the structure, and prevent sagging of the root and prevent the walls of the building from spread in g apart by internal pressure, and more particularly, to more firmly support the central portion of the arch, and bind the several members of the entire post structure more strongly together than has been possible heretofore, and thus provide a bent of this character bettor adapted to the requirements of larger buildings.

My invention is illustrated by the accompanying drawing, in which Fig. 1, is a side view of an entire bent which is made up of a pair of supporting posts alike in all rcspects, each embodying my invention, and united at the apex of the arch by a metal strap :0, and at the bottom by the base plate Y, or other suitable means.

The arched post comprises a vertical portion A for the side wall oi the building, and a curved portion B, for the roof thereof.

As heretofore, the two members of each post solidly united together as a unitary structure, the curved portion being formed by a pair of laminated members between which. spacer blocks are secured and spaced apart in the contour of the arch. As in my said former invention, the arched portion B is mainly supported centrally by the sloping post C, which is secured to the upper end of the side portion A by a lateral plate E, and a diagonal brace D extends from a notch 02 in the sloping post C, near its intersection with the plate E, to a point about midway between the spacer block a, to which it is secured by the bolt (58, and the apex of the arch, where it is secured to the spacer block a2 by the bolt cZ.

Experience has demonstrated the need of additional support at the apex of the arch,

1929. Serial No. 355,352.

and to stiffen and strengthen the diagonal brace D and the upper portion of the sloping post C, in unusually wide buildings, and to accomplish this object, I have interposed a longer diagonal beam F secured at its lower end to a spacer block a3 at or near the lower end of the curved portion of the post B, by a bolt (Z4, and at its upper end, to a spacer block a l at or near the apex of the arch by a bolt d5, as shown in Fig. 1. The beam F is further secure-d centrally by bolts 6, b, at its intersection with the brace posts 0 and D.

If desired, additional diagonal brace G may be interposed between a point opposite the lower-end of the brace post D and an intermediate spacer block a5 in the curved portion B; and cross struts s, 3, may be added, as shown, but are not deemed essential to the invention, and are not specifically claimed.

In case of feed barns, a lower story may be constructed by connecting the opposite plates E, E, with a horizontal cross beam on the dotted line 1, giving added strength to the structure and other supports may be used within the scope 01 the invention.

Having thus fully described my invention, what I claim is 1. In a truss structure, the combination with a post comprising a straight lower portion and a curved upper portion integrally united together, a sloping post extending from near the lower end of the straight portion to near the middle of the curved portion and secured thereto, a horizontal beam extending from the junction of the straight and curved portions to the sloping post and se cured thereto, a brace beam extending from the sloping post at its intersection with said horizontal beam to said curved portion at a point about midway between the upper end of the sloping post and the upper end of said curved portion and secured thereto, and a diagonal beam extending from the junction of said straight and curved portions of the post tothe upper end of the curved portion thereof and secured thereto, and across said sloping post and said brace beam, and secured thereto by bolts passed thru the several intersections, substantially as set forth.

2. In a truss structure, the combination with a post comprising a straight lower portion and a curved upper portion integrally united together, a sloping post extending from near the lower end of the straight portion to a point in the curved portion near the middle thereof and secured thereto, a horizontal beam extending from the junction of the straight and curved portions of the post to said sloping post and secured thereto, a brace beam extending diagonally from said sloping post at its intersectionwith said horizontal beam to a point in said curved portion midway between the upper end of the sloping post and the upper end of said curved portion and secured thereto, a secondary brace beam extending diagonally from the intersection of said horizontal beam and sloping post to a point in said curvedportion midway between the junction of said straight and curved portions and the upper end of the sloping post and secured thereto, and a diagill) onal beam extending from the junction of said post portions and across said sloping post and said brace beams to the upper end of the curved portion of said post, and secured to them severally by bolts passed therethru at the several intersections, substantially as set forth.

In witness whereof, I hereunto set my hand 7 this 11th day of February A. D., 1929.

CLEMENT L. EWING.
