Heating Systems specialties Armstrong Machine Works Representatives in All 851 Maple Street Three Rivers, Mich. Principal Cities Armstrong offers two types of traps for heating, air conditioning, and steam distri bution service. Standard Inverted Bucket Traps, the type originated by Armstrong, are non airbinding and self-scrubbing. They are used for Tow, medium, and high pressure service where relatively little air must be handled along with the condensate. Their free-floating lever design makes it possible to open very large discharge orifices com pared with the size of the trap itself. Armstrong Blast Traps are used where large amounts of air must be vented quick ly when steam is first turned on. They have several advantages over the conven tional float and thermostatic trap. 1. The Armstrong Blast Trap has but a single orifice to be maintained tight against the full pressure differential. 2. Positive action. The discharge valve in an Armstrong Blast Trap is either wide open or.tight shut. Fast opening and fast closing prevent wire-drawing. 3. Handles dirt. There are no dead spots in an Armstrong Trap in which dirt can settle and interfere with the operation of the trap.

F. Armstrong Steam Trap Book. This 36 page book gives complete information on all sizes and types of Armstrong Traps. It also contains 17 pages of data on the subject of trap selection, installation, and maintenance. A free copy will be mailed on request. Cross-section of No. 800 trap for straight-through pipe con nections. Part No. IS is a new steel thimble in the dis charge passage which insures positive positioning of gasket between cap and body. Cross-section of No. 801 trap for standard angle pipe connections. ALL Armstrong traps are readily convertible into "Blast" type traps merely by using buckets equipped with the patented auxiliary thermic air vent. As shown in the above sketches, the mechanism for this vent consists of a stainless steel disc slotted to receive the end of a bi-metal strip. Different coefficients of expansion in the bi-metal cause it to bend down when cold and up when hot. Normally, it is set to close at 212 deg, but it can be set to close at higher temperatures. Capacity, 50 to 100 times the air-venting capacity of a standard trap. Traps No..800-801 No. 800 No. 801 Trap Size No. 600 No. 601 Pipe Connections.........................
