Joseph H. Tourchette have invented in 1933 new and useful improvements in pontoon bridges. The invention relates to a pontoon bridge for disposal across a body of water of which the level is variable.

An object of the invention is to provide a bridge of the class described which is adapted to provide a roadway in a relatively fixed position and without regard to the level of the supporting water below it.

Another object of the invention is to provide a sectional pontoon bridge of the class described which may be assembled in place as a permanent installation.

A further object of the invention is to provide a bridge structure of the class described in which the floating sections there of are arranged to be independently removed or replaced in the assembly.

Yet another object is to provide particularly effective means for controlling the relations between the floating bridge sections and the pontoons which carry them.

The invention possesses other objects and features of advantage, some of which, will be apparent in the following description of certain embodiments of the invention which are illustrated in the accompanying drawing, in which:

Fig. 25 Is a somewhat diagrammatic side elevation of a bridge installation embodying the invention.

Fig. 26 Is a somewhat diagrammatic side elevation of another embodiment of the bridge.

Fig. 27 Is a plan view of the showing of Fig. 25.

Fig. 28 Is an enlarged elevation of a bridge section and its pontoon, the view being taken as at 4-4 in Fig. 27 (Joseph, 1933).
