To all whontit may concern: In this class of fuel-economizer it is neces- Be itknown that I, WILLIAMDOWNS, a subsary to have the apparatus as compact as posject of the King of Great Britain, and a resisible in order to save space. The headers B dent of Orange, in the county of Essex and B are placed parallel with each other and as j 5 State of New Jersey, have invented certain close together as the proper Working of the new and usefulImprovements in Fuel-Econoscrapers will permit. Each header B has the mizer Feed-Water Heaters, of'which the folrequired numben of bosses or collars I I to lowing specification is a full and clear deprovide for a junction with the upright cir- 6o scription. culating-tubes C C. These collars come quite to This invention relates to that class of apclose to each other, and one of the objects of paratus commonly known as .Greens fuelmy inven'tionis to enable the upright tubes economizer, which is used to heat the water to be placed closely together, while at the fed into steam-boilers or otherwise utilized same time ready access may be had to the by abstracting the heat from the products of space between them at their bases. This is' 15 combustion after they have left the boiler. an important point, as the scrapers are apt The invention comprises certain changes toget clogged or broken during use, and by and arrangements of the parts and construcmy improvement the great inconvenience of tion of the headers whereby it is possible to working about them with along stick or tako economize space, more readily dispose of the ing the apparatus to pieces to remove the 2o soot which collects on such'apparatus, and broken part is avoided. In order to remove particularly to more easily and readily adjust parts of the scrapers which may become loose the disarranged or broken parts of the appaor get broken, a passage-way between the ratus. upright tubes andthe inclosing wall is some- In the accompanying drawings, Figure 1 is times used and the broken parts of the 25 a side elevation of afuel-economizer embodyscrapers removed or new parts adjusted from ing my improvement.

In this way the area for flow of water down the vertical tubes to remove the soot through the header is made ample and also from their exterior surfaces. the header is made stronger to carry the 50 K represents the soot-pit, in which the soot weight of the circulating-pipes which comes collects after being disengaged from the upon it. This transverse strength may be tubes. f urtherincreased by the addition of strengthening-ribs 2 2 between the bosses and by a continuous rib 3 on the bottom of the header, extending its whole length to the points where it is supported on the walls at 4 4E. The flattening and deepening of the header in the manner last described also have the effect of exposing a larger surface to the action of the hot gases, thereby increasing the absorption of heat.
By means of this construction of header I obtain a large free space between adjacent headers at those points which are between the bases of each pair of upright pipes. This space is such as to allow access from the sootpit with the hand or otherwise for the purposes of working on or adjusting the scraper mechanism. The opening is-also of sufficient size to pass a scraper up or down through it when it is required to make changes. The larger opening also facilitates the passage to the soot-pit of the particles of soot disengaged from the circulating tubes by the scrapers.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a fuel-economizer of the character specified, the combination of a series of top boxes, outlet and supply pipe, and vertical circulating-tubes,with a series of lower headers arranged parallel, said lower headers having bosses to receive the vertical tubes, and also having laterally-contracted portions between the bosses, substantially as and for the purpose as shown and described.
2. In a fuel-econornizer of the character specified, a series of headers with bosses to receive vertical tubes, said headers being con tracted laterally and extended vertically in the portion between the bosses, in combination with a supplypipe, Vertical circulatingtubes, top boxes; and outlet-pipe substantially as and for the purposes shown and described.
3. In a fuel economizer of the character specified, a series of headers with bosses to receive vertical tubes, said headers being contracted laterally and provided with ribs and extended vertically in the portion between the bosses,in combination with a supply-pipe, vertical circulating-tubes, topboxes, and outlet-pipe, substantially as and for the purposes shown and described.
