Application filed October 27, 1900. Serial No. 34,641. (No model.)
T at, whom, it may concern: The device is attached to the steam-supply 55 Beit known tbatLWILLIAM BROAD, (whose pipe at the head 5. The steam causes the post-office address is Beaver Falls, Beaver copper strip 9 to expand, and as it expands county, Pennsylvania,) acitizen of the United the small spring 11 forces the valve to its seat States of America, residing at Beaver Falls, and closes the exit 14. When the temperain the county of Beaver and State of Pennsylture falls and the steam condenses, the cop- 6o Vania, have invented certain new and useful per strip contracts and draws the valve away Improvements in Steam-Traps; andIdo herefrom the seat, thus allowing the water to esby declare the following to be a full, clear, cape from the exit 14. and exact description thereof, reference being To regulate the device for different temhad to the accompanying drawings, which peratures, the plug 12 is screwed in or out to form a part of this specification. decrease or increase the distance between the This invention relates to certain new and valve and its seat. useful improvements in an automatic steam- The device will work equally as well when 15 condensing trap.
