WILLIAM I4. CHURCH, OF NEW YORK, N. Y., ASSIGNOR T AMBURSEN COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF NEW JERSEY.

REINFORCED CONCRETE CONSTRUCTION.

Original No. 1,097,915, dated Kay 26, 1914,

To all whom it may concern:

Be it known that I, WILLIAM L. CHURCH, a citizen of the United States, and a resident of New York, in the county and-State of New York, formerly a resident of Boston, Massachusetts, have invented a new and use ful Improvement in Reinforced Concrete Construction, of which the following is a specification.

The present invention relates to remforced-concrete construction, and its object is to provide a method of makin a practicable, efficient and economical remforcedconcrete roof.

One form of roof made in accordance with m method is illustrated in the drawings w ich accompany and form a part of this s ecification, although it will be understood t at various modifications ma be made in details of construction of t e particular roof shown without departin from the invention defined in the appen ed claims.

In the drawings :F igure 1 is a perspective view of my improved reinforced-concrete roof; Fig. 2 is a transverse section thereof, and Fig. 3 is a perspective view of a detail of construction.

In the particular drawings selected for more fully disclosing my invention, 1 represents a supporting beam constituting a part of the wall of a building herein shown as formed of concrete reinforced by the rods 2. At suitable intervals along the top of the beam are placed oppositely disposed saddles or gaggers 3, preferably of concrete, ar ranged to have their holes 4, shown in the present instance as three in number, in ahnement. The saddles com rise, as shown, a flat base portion, prefera ly equal in length to the thickness of the beam on which it rests, and two upwardlv-extengling divergin arms.

inforcing members 4, herein shown as round rods but which may have any suitable section, are passed through the holes 4 of each pair of saddles as shown in Fig. 2, and the reinforcing member 5-, which may consist of a sheet of wire-mesh, expanded metal or the, like, isbent into appropriate shape and supported in the saddles. In the articular construction illustrated in the drawings, the reinforcing member 5 is shown as wire-mesh bent sinuously and the Specification of Reissued Letters Patent. Reissued J uly 21, 1914,

Serial No. 845,139.

lowermost parts thereof rest in the saddles and on the rods 4 between the saddles. When the reinforcing member, bent into any suitable shape, has, been placed in position, concrete, cement or the like is applied to both sides thereof, preferably by forcibly projecting the same by means of a cement gun. I prefer to first coat the under side of the member to form the concrete or cement coating 6, which is about equal in thickness to that of the arms of the saddle, and afterward theupper side. As shown at 6 the rods 4 are embedded in the finished structure and the roof is slightly thicker at this point than elsewhere. After the coating operation has been completed, manually or otherwise, the saddles, if of concrete and said coating form a homogeneous structure, and the rods 4 and member 5 are embedded therein,.resulting in a roof of great strength and durability.

While in the drawings I have shown the alternate ridges and gutters parallel to the slope of the roof, they may be arranged parallel to the ridge-pole, and eaves, or at any other angle.

If desired the saddles may be omitted, and th(ei reinforcing member 5 supported by the re s.

It will be obvious that the reinforcing member may be stamped or otherwise formed in various shapes, thereby giving the roof when com leted, the appearance of ornamental, over apping tiling.

I claim 1. The method of forming roofs consisting in placing spaced pairs of saddles on supports, resting the gutter portions of a sinuous foraminous metallic sheet on said saddles, and applying coatings of cement to both sides of said sheet.

2. The method of forming roofs consisting in placing spaced airs of saddles on supports, connecting eac air of saddles by reinforcing bars, resting t e gutter portions of a sinuous foraminous metallic sheet 011 said saddles, and applying coatings of cement to both sides of said sheet and causing one of said coatings to cover said bars.

3. The method of forming roofs, consisting inplacing spaced pairs of saddles on supports, resting the gutter portions of a sinuous foraminous metallic sheet on said LOO saddles, and applying coatings of cement. ment to both sides of said sheet and causing to both sides of said sheet and-engaging said saddlesto for-In a, homogeneous structure.

4:. The method of forming roofs consisting in placing spaced sets of reinforcing bars on supports to connect the opposite Walls of a building, resting the gutter portions of a sinuous oraminous metallic sheet 10 on said bars, and applying coatings of ceone of said coatings to cover said bars.

In testimony whereof, I have hereunto subscribed my name this 12th day of June, 1914. 7

WILLIAM L. CHURUH.
