To all whom it may concern.- to open either in unison or separately, so that, Be it known that we, W'ILLIAM DOWNS, reif desired, part of the economizer can be siding at New York, in the county of New worked circulating and part non-circulating.

In than those involved in the present invention, the pipe B are'arranged the same construe 5 5 our invention enabling the eeonomizer to be tion or style of valves V, the first of which used either as a positively-circulating appais disposed between the second and third ratus or as a natural circulating 011e, with full tiers of pipes, as shown, and the others arcommunicationthroughout the nest of pipes, ranged at intervals embracing two tiers of and also enables the apparatus to be blown pipes, so that the water discharged from the I00 50 off with one main blow-off valve by simply first is directed to the second. The two sets opening the wing-valves, which are arranged of valves are disposed in alternation, relatively to each other, as shown in the drawings. ,7

The valves are essentially of the wing variety, and consist of metal disks fitted suitably in the pipes, and mounted on journals or stems 8, let through guides or caps 9, and carryingon their outer ends arms 10, the free ends of which are detachably connected to a valve-rod 11, so that they can all be opened and closed by a single movement of the valverod,or so that by removing the pivot-screw 12, which holds the arms to the valve-rod, any number of the valves may be opened, that part of the economizer converted into a natu ral circulating apparatus, and the balance of it be used as a positivel y-circulatin g apparatus.

To use the apparatus as a positively-circulating one, the valves are all closed, and then the water will be directed back and forth across the apparatus, flowing up one tier and down the other; and if it is desired to convert the apparatus into a non-circulating economizer the valves are all opened.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is'

1. In a fuel-economizer or feed-water heater, the combination with the nest of pipes, the feed-pipe 2 connected with one tier thereof, the top pipe 4 communicating with the other end ofthe pipes of said tier, a top pipe 5 communicating with the top pipe 4 and with one end of the nest of pipes of another tier, a bottom pipe 7 at the opposite end of the pipes of the last-named tier, a blow-off pipe B communicating with the bottom pipe 7, the combined access and blow-off pipe B having communication with all the tiers of'pipes at one end, the top delivery header or pipe B having communication with the opposite ends of all the tiers of pipes, and valves alternately disposed in the feed-pipe and the deliverypipe, whereby the apparatus may be converted from a non-circulatin g into a positive circulating apparatus.

2. In a f uel-economizer or feed-water heater, the combination with the nest of pipes, the feed-pipe 2 connected with one tier thereof,

the top pipe 4 communicating with the other end of the pipes of said tier, a top pipe 5' communicating with the top pipe 4: and with one end of the nest of pipes of another tier, a bottom pipe 7 at the opposite end of the pipes of the last-named tier, a blow-off pipe B communicating with the bottom pipe 7, the combined access and blow-off pipe B having communication with all the tiers of pipes at one end, the top delivery header or pipe B having communication with the opposite ends of all the tiers of pipes, and valves alternately disposed in the feed-pipe and the deliverypipe, arms on the stems of the valves, and a valve-rod on the free ends of the arms, whereby the valves may be opened and closed in unison.

3. In a fuel-economizer or feed-water heater, the combination with the nest of pipes, the feed-pipe 2 connected with one tier thereof,

the top pipe 4: communicating with the other end of the pipes of said tier, a top pipe 5 communicating with the top pipe 4 and with one end of the nest of pipes of anothertier, a bottom pipe 7 at the opposite end of the pipes of the last-named tier, a blow-off pipe B communicating with the bottom pipe 7, the combined access and blow-off pipe 13 having communication with all the tiers of pipes at one end, the top delivery header or pipe B having communication with the opposite ends of all the tiers of pipes, and valves alternately disposed in the feed-pipe and the deliverypipe and formed with stems, arms in the ends of the stems, and a valve-rod detachably connected to the ends of the arms, whereby some or all of the valves may be operated by the valve-rod.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
