STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 530,901, dated December 11, 1 894.

' Application illed February 7, 1894. Serial No. 499,366. (No model.)

To aZZ whom it may concern:

Be it known that LALBERT F. L. REUssNER, of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Steam-Boilers; and I do hereby declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled 1n the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in boilers and has for its object the production of a boiler possessing advantages in point of simplicity, durability and inexpensiveness, and in which the steam can be readily generated and the cold water supply is not affected by the `heat or products of combustion and all choking is avoided.

A further object is to provide an improved boiler in which water-backs lor walls are formed at the sides and ends of the boiler.

A further object is to provide a boiler wherein access can be readily had to the dif# ferent parts for the purpose of cleansing and in which any injured part can be readily removed without disturbing the other parts of the boiler. y

The invention comprises the novel features of construction and also the combination and arrangement of parts, substantially as hereinaftcr fullyset forth and particularly pointed out in the claims. v

In the accompanying drawingsz---Eigure 1 is a vertical longitudinal sectional view of my improved boiler with a portion only of the inclosing casing. Fig. 2 is a plan view. Fig. 3 is a front end view.

Referring to the drawings, A designates the inclosing casing; d, the grate; a', the lire-box a2, the ash-pit, and a3 a curved bridge to direct the passage of the products of combustion.

B designates a series of inclined tubes opening at their ends into two series of horizontal headers b, b'. These tubes B are staggered, that is, each tube is located above or below the intervening space of two tubes in the adjacent row of tubes. The horizontal headers o, b', are extended transversely, relative to tubes B, and are placed one upon the other, forming complete water-walls or backs at each end ofthe boiler. At their ends these series of headers, b, b', are, respectively, connected by nipples b2 and end-caps b3 with two sets of standpipes C, C,`the former constituting an uptake and the latter a downtake, said latter stand-pipes being connected at their lower ends to a mud-drum D, when desired, and at their upper ends to a horizontal steam-drum E to which the uptake stand-pipes connected by upper steam-pipes d, and lower tubes d extending from an upper horizontal pipe d2 and opening into said drum at apoint beneath the water-line.

cA is the dry-pipe and e. the feed-pipe.

In order to increase the capacity of the boiler and extend the action of the products of combustion over as great an area as practicable I form side-water-backs extending the length of the boiler. These water-backs are composed of tubes F opening at their ends into the stand-pipes ofthe up-takes and downtakes, said tubes being placed one upon the other and forming complete walls throughout the length of the boiler. This construction is of special advantage in marine-boilers, but in stationary boilers these tubes F may be dispensed with and brickwork substituted. Itwill also be understood that in marine-boilers the mud-drum is not required.

The stand-pipes C, C', have plug-covered hand-openings f so located that accessv can be readily had to one of the headers and the sidetube F opening on a line therewith. Thus the tubes and headers can be readily inspected and cleaned. Should any of the headers or tubes be damaged such part can be readily removed and another substituted without disturbing the remaining parts of the boiler.

NOR or onn- C are also 6p In order to direct the passage of the pro- 9c ducts of combustion and to aid in preserving the position of the longitudinal tubes the latter are preferably passed through openings in two plates or bridges G, which cause the products course.

passing from It will be observed that the heat in the boiler travels over the water-back formed by the rear series of headers and between thev two end stand-pipes. Hence the heat not striking against or passroo ing between the cold-water conductors the operation of the boiler is not impeded bybankof combustion to travel a circuitous 9 3 ing or choking. In this way the minimum heat only approaches near to contact with the cold-water conductors or down-takes.

The advantages of my invention are apparent to those skilled in the art to which it appertains, and it will be specially observed that I have produced a boiler having a maximum capacity and that the arrangement of the tubes is such that steam can be readily generated and conveyed from the up-takes through the steam-pipes to the drum, from which, or any point of said steam-pipes, connection may be made for carrying away the steam. It will also be noticed that any water passing through the uptakes will be conveyed back to the steam-drum through the series of tubes leading thereto from said uptakes, said tubes being located above and outside the top of the casing.

A boiler'constructed as herein described is efcient in operation, is strong and durable, inexpensive and simple in construction.

I claim as my inventionl. Aboiler havingaseries oflongitudinally- `extended tubes inclined: from front te rear, a forward, upper series of transverse horizontal headers, a rearward, lower series of transverse horizontal headers, said tubes opening into said headers, cold water being supplied to said rearward, lower series of headers at the ends thereof, and deflector plates or bridges, substantially as set forth, whereby the products of combustion are caused to pass out over the top of said rearward, lower series of headers, as stated.

2. A boiler having a series of longitudinally extended tubes inclined from front to rear, a forward, upper series of transverse horizontal headers, a rearward, lowerseries of transverse longitudinal headers, said tubes opening into said headers, forward and rearward sets of perpendicular stand-pipes into which both of said series of headers open at their ends, said rearward sets of stand-pipes being designed to supply cold water to said lower series of headers at the ends thereof, and the plates or deflectors through which said inclined tubes are passed, substantially as set forth,whereby the products of combustion are caused to pass out over the top of said rearward, lower series of headers and between said rearward sets of stand-pipes, substantially as set forth.

3. In aboiler, the combination with the longitudinally disposed inclined tubes and two sets of stand-pipes connected thereto, of the steam drum to the under side of which one of said sets of stand -pipes is connected, the outer pipes connecting the other set of standpipes to said drum, and the series of tubes extending from said latter stand-pipes to said drum below the water-line therein, substantially as set forth.

4. Aboiler having aseries of inclined tubes, horizontally disposed headers to which said tubes are connected, two sets of stand-pipes into which said horizontal headers open, and the series of inclined tubes connecting the opposite stand-pipes of each of said sets,substantially as set forth.

5. A boiler having a series of inclined tubes, two sets ot' stand-pipes, two sets of headers, the headers ofeach set being arranged one upon the other and having the said inclined tubes opening thereinto, and forming waterbacks, said headers opening at their ends into said stand-pipes, and the two side series of tubes connecting the opposite stand-pipes of said sets, the tubes of each series being arranged one upon the other, forming side wa ter-walls or backs, substantially as set forth.

6. The herein-described improved boiler consisting of the series of inclined staggered tubes, two series of horizontal headers into which said tubes open, said headers resting one upon the other, two sets of perpendicular stand-pipes into which said headers open at their ends, forming up-takes and down-takes, the series ofinclined tubes connecting the opposite stand-pipesl of said sets ot' standpipes, the steam-drum to which said downtake stand-pipes are connected, the steamppes'and the series of tubes connecting said up-take stand-pipes to said drum, substantially as set forth.

7. In a boiler, the combination with the casing, of a series of longitudinally disposed water tubes, a steam-drum located outside of said casing, perpendicular 11p-takes leading from said water tubes through said casing and having direct connections outside thereof with said steam-dru m, one of said connections being above the other, the lower connection leading into the water space of said drum, and the other into the upper or steam space thereof, whereby the steam and water are separated before entering the steamdrum, substantially as set forth.

8. In a boiler, the combination with the casing, of a series of longitudinally disposed water tubes, a steam-drum located outside of said casing, perpendicular stand-pipes with which said water tubes communicate at their ends, upper pipes located outside of said casing connecting the forward stand-pipes or uptakes with the upper portion or steam space of said steamdrum, and lower water tubes also located outside of said casing leading from said uptake stand-pipes to said drum beneath the water-line therein, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscrib ing witnesses.
