HENRY IVHINFIELD, OF NFV YORK, N. Y.

STEAM-BOILER.

Specification of Letters Patent No. 19,669, dated March 16, 1858.

T o all whom it may concern.'

Be it known that I, HENRY VVHINFIELD, of No. 6 Vall street, in the city, county, and State of New York, have invented certain Improvements in the Construction of Steam- Boilers; and I do hereby declare that the following is a full, clear, and eXact description of the principle or the character Awhich distinguishes it from all other steam-boilers before known and of the manner of making and using the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure 1- is a section of a boiler with one longitudinal tube or flue connected latitudinally with tubes or flues to the sides and vertically with tubes or flues to the bottom, intended for locomotive engines. Fig. 2-d is a section of a boiler with two longitudinal tubes or flues connected latitudinally with tubes or fines to each other and to the sides and also connected vertically with tubes or flues to the bottom. Fig. 3 is a section of a boiler with siX longitudinal tubes or flues connected latitudinally with tubes or flues to each other and to the sides and also connected vertically with tubes or fluesto the bottom. Fig. i is a latitudinal section of Figs. 5, 6 and 9 at (a, a). Fig. 5 is a longitudinal section of Figs. 7 and 8 at (Z9 b) showing the inside of the tubes or flues, fire box, ire water back and descending flue or chimney and boX for heating air and water. Fig. 6 is a longitudinalsection ofv Figs. 7 and 8 at (o c) showing the outside of the tubes or flues and boXes for heating air and water, with pipes to conduct the heated air into the boiler. Fig. 7- is an elevation of the chimney end of the boiler showing a section through Fig. 5 at (d d) of the boX and pipes for heating the air, also receiver and the pipes to conduct the heated air into the boiler. Fig. 8- is an elevation of the front ofthe boiler showing fire doors, man-hole door, and cleaning places. Fig. 9- is a side elevation of the boiler showing cleaning places, boX to heat water and air, and pipes for conducting the heated air into the boiler.

The nature of my invention consists in forming a steam boiler with the usual fire boX (B), with one or more or any number of longitudinal tubes or flues (E), latitudinal tubes or iues (F), and vertical tubes or flues (G), all connected together and to the sides, ends, and bottom of the shell of the boiler, as shown in Figs. l, 2, 3, 4, 5 and 6 in the usual manner as heretofore described; making one of the strongest boilers in use. The importance of this arrangement, is, the non-combustible gases will be separated from the combustible gases, which are, in consequence of the combination and arrangement of all the parts forming the boiler, herein described, retained in said tubes or flues, and consumed as represented in Fig. 5, to wit: the pointed darts represent the light or combustible gases, ascending after separation, which are then and there consumed, causing a great saving in fuel. The round or blunt ended darts represent the heavy or non combustible gases descending down through the vertical tubes or flues (Gr), into and along the half tubes or flues (H), whichrepresents the bottom of the boiler to the descending flue or chimney (I), which are thereby carried ofll during the separation of the gases as heretofore described.

To insure the most speedy combustion of the gases, I apply a blowing machine or equivalent to force air through the pipe (It), contained in the boX (K), which2 air is there heated; and the heated air is then forced into and through thereceiver (S), thence into the pipe (L), and small pipes (M), into the boiler through the latitudinal tubes or lues (F), and thence into the longitudinal tubes or flues (E), and vertical tubes or. flues (Gr), for the purpose of assisting the more speedy combustion of the combust-ible gases as hereinbefore described and therein contained. By this process the intensity of heat generated is in proportion to the amount of oxygen forced into the boiler by the blowing machine or equivalent; and consumed; resulting in great economy of fuel, which is the great feature of my invention.

The continuous combustion of the gases as heretofore described, in the tubes or flues '(E, F and G), during their separation, cre- .box and flues over the fire.

I place on the receiver (S), for heated air a regulating valve similar' in construction to a steam safety valve' for the purpose of increasing or decreasing the volume of heated air forced into the boiler through the small pipes (M). I also place on the boiler tyvo Ventilating doors (U), one on each side of the bottom of the chimney (II), as illustrated in Fig. 9 for the admission of cold air, which Will greatly assist the operation of the boiler in retaining the combustible gases in the tubes or flues by opening one or both of said doors, and they can also be used to remove any deposit at the bottom of the chimney.

The operation of cleaning the tubes or flues can With great facility be performed through the oval holes (P), on the sides and ends of the boiler, and the dirt or refuse from the tubes or Hues Will fall through the vertical tubes or ues, onto the ground by first opening the movable or false bottom (Q), which can be replaced with ease.

To enable others skilled in the art to make and use my invention, I Will proceed to describe its construction and operation.

I construct my steam boiler of the usual materials in any of the known forms, with a fire box (B), and furnace bars (C), in the usual manner; with a vertical Water back D), extending above the half tubes or flues (H), forming the bottom and a certain arrangement of one or more longitudinal tubes or flues (E), as in Figs. 5 and 6, of any diameter proportionate to the size of the boiler, and connected (when more than one are used) With one or more or any required number of latitudinal tubes or flues (F), of proportionate size (as in Figs. l, 2, 3 and 6), to each other, and to the sides of the shell of the boiler (A). The said longitudinal tubes or flues E), are also connected together with one or more or any required number of vertical tubes or flues Gr), of proportionate size to each other, and to the half tubes or tlues (I-I), forming the bottom of the boiler (A), which bottom (I-I), is formed of longitudinal half circles or half tubes or flues, and inclosed by the movable or false bottom (Q), Working or moving on a hinge or oint forming a communication with the flue, chimney, or smoke pipe (I), the damper (J), and the Ventilating doors (Il), by opening one or both as may be required the combustible gases Will be retained in the tubes or iues of the boiler Without the constant use of the damper (J), as represented in Figs. 5 and 6.

In the rear of the boiler there is placed a box (K), as Wide as the boiler, and extending vertically about half or three-quarters the height of the boiler, Which box (K), is heated with the gases from the boiler through the ends of the longitudinal tubes or ues E), and is constructed as shown in Figs. 6, 7, and 9 and acting as a heater to heatthe air passing through the pipes (L) therein contained: to Wit: pipe (R), connects With a blowing machine for the purpose of a continual supply of air; which air is heated in the pipes or compartments contained in said box (K), and forced into the receiver (S), thence through the pipes (L), and small pipes (M), or mouth pieces connecting said pipes L), With the boiler into the latitudinal tubes or flues as herein described.

In the rear of box (K), I place a receiver (S), for the purpose of heating Water prior to its injection into the boiler by the force pump. Said receiver is heated on one side by the said box (K), and by the chimney or flue (I), passing up through the Water in said receiver.

Having thus described my invention, what I claim as ne\v,.original, and useful, and desire to secure by Letters Patent is- The arrangement of the longitudinal, latitudinal or transverse and vertical fire tubes or flues as herein set forth. HENRY VVHINFIELD.`
