SPECIFICATION forming part of Letters Patent No. 382,722, dated May 15,1888.

Application filed February 23, 1888. Serial No. 264,907. (Yo model.)

To aZZ whom it may concern..-

Be it known thatI, GEORGE F. NILssoN, of

Belmont, in the county of Middlesex, State of Massachusetts, have-invented a certain new and useful Improvement in-Boilers, of which .ing part of this specification, in which Figure 1 is a vertical longitudinal section of my improved boiler and its casing, taken on line main Fig. 2; and Fig. 2, a vertical trans- ;erse section of the same, taken on line yy in Like letters and figures of referenceindicate corresponding parts in the different figures of the drawings.

My invention relates more especially to that class of boilers which are used for heating purposes, both with steam and hot water; and it consists in the certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler and more effective device of this character than is now in ordinary use.

The nature and operation of the improvements will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the boile r proper, B the chimney or smoke-stack, O the fire-box, and D the casing, these ,parts being all of the ordinary form and construction. The boiler A is also supplied with a steam-dome, A' vertically-arranged pipe, 00, enters the under side of the boiler near the rear end thereof, a horizontally-arranged pipe, 2, being centrally conneoted to the lower end of the pipe as and extending out through the casing D at each side thereof, as shown in Fig. 2. A longitudinallyarranged inclined pipe, '12, connects each end of the pipe .2 with the end of a horizontally-ar ranged pipe, f, which rests on the bridge-wall H, near the fire-box, and extends through the casing D, said pipes '12 being also outsidesaid casing. A horizontally-arranged pipe, m, is disposed on the bridge-wall H below the rear end of the boiler, said pipe extending through the.casing D and being provided with a valve or faucet, it, (see Fig. 2,) at one end. Two shortinolined pipes, (see Fig. 1,) connect the ends of the pipe z with those of the pipe' m outside the casing. A horizontally-arranged pipe, h, is disposed beneath and near the head of the boiler, said pipe passing'through the casing D. A vertically-arranged pipe, z, is secured to each end of the pipe h and passes back through the casing into the boiler..A at

1, or just below the water-line, one end of the pipe h being provided with a valve or faucet,

1). Eight longitudinally arranged-inclined pipes, q, connect-the pipe h with the pipe m,

and a corresponding number of vertically-arranged pipes, 1, connect the pipes q with the P f- In the use of my improvement the boiler A is filled with water, in the usual manner,which passes into and fills the pipes described. Fire being started in the fire box, the pipe h and adjacent portions of the pipe q become heated first, causing the heated water in said pipes to rise through the pipesiinto the boiler just below the water-line, thereby producing a cir-' culation of water between the boiler-system of pipes beneath it, which becomes continuous.

The heated air, smoke, and products of combustion from the fire-box pass in the direction indicated by the arrows in Fig. 1, through the fiues d of the boiler, in the usual manner, thus keepingthe water in said pipes constantly.

heated to a high-temperatu re. Steam is taken from the boiler A for heating purposes in the usual manner, and by attaching pipes to the valves 0 t hot water may be conducted to any position desired and a continuous circulation kept up through the same, as described. Moreover, byusing my system of pipes I find that the boiler A may be constructed about onethird the size ordinarily required to produce a given result, thus effecting a great saving in the cost of construction.

I do not confine myself to using any specific ICO .body at the rear on the'under side thereof, a'

transversely-arranged pipe connectedeentrally with said vertical pipe and extending through pipe at the rear of the bridge-wall, and vertical pipes connecting the ends of the transverse pipes and the body of the boiler below the water-line, all being arranged to operate substantially as set forth. 2o

2. In a boiler, the body or boiler proper,A. having the flues d and dome E, the vertical pipes at r i, transverse pipes z mf h, inclined pipes q o g, bridge-wall H, and casing D, combined and arranged to operate substantially as 25 set forth.
