Crosby steam engine indicator, by the Crosby Steam Gage & Valve Co., 1879-1896

This indicator, patented by Mr. G. H. Crosby, of Massachusetts, U.S.A., in 1879-82, is specially designed for taking diagrams from quick revolution engines. For this reason the size and weight of the moving parts have been reduced and their travels shortened, so as to minimise the disturbances due to momentum.
