Nearly four years (1861-4)were largely given to experiments withgas checks. An inventor named Dreyseinvented a imper obstructor to preventthe gas from exploded powder escapinginto the breech, where its erosive poweris injurious. This paper check had theadvantage of accommodating itself well to the bore, and the disadvantage ofhaving to be too frequently changed ;i. e., after every nine or ten shots. AnAmerican inventor substituted copper forpaper in the gas check that bears hisname, the Broadwell Ring, and it isgenerally stated in treatises on ordnance r. THE BREECH ANALYZED. {e. g., Cooke, Brooke, Maitland, etc.) thatthis is used in Krupp cannon. Such,however, is not now the fact. The gascheck used is a combination of copper andvery elastic steel, made into a ring nar-rower than the Broadwell, the thin rimof which is almost hermetically sealedby the explosion upon the nose of thebreech.
