To tu whom t may concern:

Be it known that I,LOUIS LANE, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented anew and Improved Arch, of which -the following is a full, clear, and exact description.

This invention relates to improvements in the construction of small arch bridges, culverts, and the like, the obj ect being to provide an arch for such structures of simple construction, easy to build, durable, and cheap.

I will describe an arch embodying my invention and then point ontthe novel features in the' appended claims.

Reference is to be hadto the accompanying drawings, forminga part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of an archl embodying my invention.k Fig. 2 is a sectional elevation showing amodification. Fig. Bis a sectional detail showing a form of key vernployed in the structurev` illustrated in Fig.l 2, and Fig. 4 is a section on the line'x of Fig. 3.

Referring to the drawings, 1 designates the abutments, on the upper portions of which are placed the angle-irons or skewback-bearings 2 to receive the ends ofthe arch-plates 3. In the construction of the arch dowels 4 may be placed inthe material :rearward of the angle-irons, so as to prevent any possible displacement of the angle-irons during such construction.` The plates 3 are of any suitable thickness, and to provide for a considerable strength with a comparative lightness of a plate or plates the said plate or platesarecorrurgated from sidepto side`that is, in the direction of .their curve. After-placing the plate or plates 3 the arch ring 5 isplaced in position, this arch rin g consisting of concrete, and between the concrete and the plate or platesa rich mortar isused, the metal and concrete being Vstructurally united by reason of the well-known propertyfof adhesionof cement to iron, and forms a compounded struc- -ture of` great strength and efficiency. The

metal also being on the under exposed side forms a shell to protect the concrete from the elements or from other injury. The metal arch I prefer to have a rise of approximately onefourth its span and is one that may be of the socalled lineal-archi form. By thus propor tioning and employing thev metal arch-plates I save vthe trouble and expense of temporary 5 5 centering, which has rendered the use of such arches impractical in many localities, owing to the great diversity of lsize and proportions.

In Fig. l I have lshown the arch-,plate as made in one length from'side to side, and this is used where a limit ofjone hundred and twenty inches for Vsuch sheets will permit it. Where the span exceeds this, I overcome the diiiculty by a special construction, as illustrated in Fig. 2, v l

l In Fig. 2 I show the arch as comprising two corrugated plates 6 and 7, which at their upper ends connect with a key comprising a bar 8, having iianges 9 10 at the upper and lower sides, which project to engage the upper and lower surfaces of the arch-plates, these plates 9 and. l0 beingbolted to the bar 8, as clearly shown in the drawings. Having thus described my invention, I clai-mas new and desire to secure by Letters Patent v j 1.1' An arch,comprisingabutmentsbearingirons on said abntments, dowels with which the rear sides of the irons engage, an archplate mounted on said bearing-irons, the said plate being corrugated in the direction of its curve, and a concrete-arch ring, substantially as specified.

2. An arch, comprising abutments archplates resting on the abutments and extended at their upper ends to the lcenter of the arch, and a key connection between said upper ends, and engaging with theupper and unger1 sides of the plates, substantially as specie( a v 3. 4An arch, comprising abutments, archplatesspringing from' said abutments, the 4said plates being 'corrugated in the direction f of their curve, a key-bar arranged between the upper ends of the plates, and plates se- 95 cured to said bar and engaging against the upper and under surfaces of the arch-plates, substantially as specified.

In testimony whereof I yhave signed my name to this specification in the presence of roo two subscribing witnesses.
