The central bore 27 of bonnet 26 is of enflici'ent diameter to pcrmitaaid bonnet-to ride loosely on'thecnd of stem 17, the upper e bore, h -P portion of said stem17, as shown in Fig. 1. 1i) and thence throuph gg e c e fills with water its buoyancy is time over- 97 being contracted be timed by the pointed of "u'lsion of 28 isa pet cock to permit the ex the air-(contained in the trap un blow out plug adjacent casing 1 to cuuble. the sediment collecting therein to be blown out when desired. , The mcpfiration of my invention is as follows:-- e steam is admitted through port 2, the pet cook 28 being left open for -a moment to permit the escape of the air. The steam "and water entering through port 2 are thrown to the: bottom of easing 1 by means of balile 3. The admission of the steam and water fleets bucket 16 upwardly gtil the stem 17 fozfifigbe 'bglfiet 2 6 in; oee engagement wi e ring thus closing the bored said pa ing ri and the bore of the plug .12. The pain end of stem 17 closes the bore 27 of bonnet 26, the parts thus asuming the relative .pomtions shown in Fig. 1 and all access through the orifice 9being thus cut ofl. The casing 1 gradually fills with water deposited by the steam. until oi the bucket 16. As said bucket come and it sinks, drawing down with it the stem 17 thus disengaging the. pointed end of said stem 17 from the ibore 27 of the bonnet Fig. 2. By means of the 26, as shown in gauge of steam thro I h the bore of bonnet the pressure is paired on each end of said bonnet permit the same to drop within member 19 into the position shown in 3, thus opening the pass through packing ring 21 and pu 12. e pressure within the casing now ms the water in the bucket 16 up through tube 11 into orifice 9, ports 23-23 into the interior of member the bores of the acking ring 21 and pu g 12 to the erge ipe, not shown. Alseoon us enough water 15 exhausted irom th'ibucket to restore its buoyancy, the bucketin in rises in the casing 1 until the pointy: end of stem 17 raises the bonnet '36 into thecposition shmvn in Fig. 1,.thus completely osing the-dincharge openings u'ss own in Fig. 1. It is thus evident that .us often as suflicient water overflows into bucket 10 to overcome. its "buoyancy, the some will be automatically i one the limited number of parts u avoiding the greater portion of the original to the bottom of a casing, therefrom, the upper part of said cost of the well known types of steam traps now m use.
