securely clamped-31in place on the 1: valves.

In Figs. l and 5 I have shown amodnied construction, which consists in provlding plates 19 and 20 an'd19 and 20, arranged inpairs withhinges 2l'at their abutting" the plates 19 and 20, whose hin'ge,being on the,.,out side, may extend -the length of these plates. ,lPanelvopenings 22 are provided. in

the plates, in which the glass sections 14c, are inserted in substantially the same way as described with reference to the previous.
