8634. Parsons, R. April 14. Steam traps.-Relates to steam traps, particularly of the type described in Specifications No. 4662, A.D. 1895, and No. 20,932, A.D. 1899, in which the operation is effected or controlled by the volatilization of a volatile liquid or substance contained in a condenser chamber, and especially to the fixing in position and protecting of the condenser chamber in that kind of steam trap. Various methods of fixing the condenser chamber a in its case bare shown in Figs. 1, 3, and 12. The vertical sides b1 of the case b are internally or externally threaded to receive the flanged and screwed ring c, which bears against the chamber a by the flange c1. The ring c and internal flange c1 may be merged in one, and the ring may have pin-holes or slots to enable it to be rotated. The case b, in the modification shown in Fig. 3, and in another modified form, is flanged, and the ring c is screwed to the flange. The ring c may be provided with a thin metallic diaphragm or top hermetically sealed to the ring. In the modified form shown in Fig. 12, a screwed ring screws within the flanged ring c. In a further modification, the ring c has inclined slots to fit over screwed pins carried by the case b, so that, by turning the ring and tightening nuts on the pins, the parts are held in position. Suitable packing is used between the ring c, the chamber a, and the case b. The ring c may have fitted to it a protecting-cover e, Fig. 5, having air openings e1 in it, or the cover may have vertical ribs which act also as radiating parts.
