IMPROVEMENT IN` ARCHES FOR BRIDGES.
Specification forming part of Letters Patent No. 125,128, dated April 2, 1,872.
To all whom it may concern:
Be it known that I, DANIEL FORARGUE, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Arches for Bridges, &c., of which the following is a specification, reference being had to the accompanying drawing making a part` of this specification, in which- Figure lis a side elevation of the arch. Fig. 2 is an end view. Fig. 3 is a plan view. Fig. 4 is a view of the under side.
Like letters of reference refer to like parts in the several views presented.
The nat-ure of this invention relates to an arch for bridges, roofs, Src.; and the object thereof is to combine in said arch the lightness and strength of the trestle-brace and channel-iron plates, thereby making a light, strong, and durable structure for the aforesaid purposes.
In the drawing, Fig. 1, A B represent the upper and under side of the arch, each of which consists of a plate of metal, having their two edges turned at a right angle, forming flanges C on the inner curve line of plate A and on the outer curve line of plate B, by which lian ges the plates are formed into channelirons. Interposed between the two plates, and secured thereto by the bolts a, is a series of braces, D. Said braces consist of a strip of metal of the proper width and thickness for a brace, which is then bent so as to form a series of triangular braces, D, referred to; hence all the braces are formed of one continuous strip of metal, according to the length of the span of the arch and the convenience of handling, but which, however, may be of short length or separate braces, as the work may demand. One series of the braces is placed between'the upper and lower plates, so that the side shall be close to the inside of the flange, which is then secured to the upper and lower plates by means of rivets or bolts a passing through the plates and the apex ofthe angle of the braces, as shown in Fig. l. A second series of braces is placed correspondingly on the opposite side, along and close to the flange, and which are so arranged in relation to the rst series that the apex of the angle of the braces on one side is opposite the base of the angle ofthe braces on the other, so that each separate brace of one series crosses that of theother, thereby mutually bracing each other, as shown in the side view, Fig. l. A section of the ange in said figure is represented as being broken away in order that the relative positions of the braces to each other and their connection to the plates may be seen.- The ends of the arch are secured in foot-blocks E, and which are tied to each other by stringers F, said stringers being supported by the suspension-rods G. Upon the stringers are laid the cross-ties or bea-ms H, on which the floor F of the bridge is laid. The bridge is braced transversely by the diagonal rods J, Fig. 4, thereby completing the structure, which is not only comparatively light, but it is also strong, durable, and easy to construct.
Claim.
What I claim as my invention, and desire to secure by Letters Patent, is-
An arch for bridges, consisting of channeled irons or plates A B, arranged in relation to each other, as shown, in combination with a continuous system of braces, consisting of one piece, in the manner as described, and for the purpose set forth.
