UNITED STATES WILLIAM H. RICKER, OF CAMBRIDGE, MASSACHUSETTS.

CONSTRUCTION OF BOILERS.

Specification of Letters Patent.

Application filed April 13, 1910.

Patented Feb. 14, 1911. Serial No. 555,196.

To all whom it may concern:

Be it known that I, lVILLLmr H. Brenna, a citizen of the United States of America, and a resident of Cambrid e, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in the Construction of Boilers, of which the following is a specification.

This invention relates to steam boilers and has for its object the production of a boiler in which the tubes are made with double walls leaving an annular space through which the water circulates, said water being subjected to heat caused by the products of combustion passing through the interior of said tube and around the exterior thereof.

The invention consists in a novel construction of vertical standpipes to which the various tubes are connected, said vertical standpipes being made up of a plurality of sections locked together by some suitable means, each of which sections communicates with the annular passage in one of said tubes while a central passage is provided through which the products of combustion are free to pass.

The invention further consists in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a boiler embodying the features of the present invention. Fig. 2 represents a front elevation, shown partly in section, of a plurality of vertical standpipes. and the horizontal pipe communicating with the upper ends of said standpipes. Fig. 3 represents an elevation partly in section of one of said standpipes showing a plurality of tubes communicating therewith, the cutting plane being on line 3 3 on Fig. 2. Fig. ti: represents a hor izontal section through the same, the cutting plane being on line l-l: on Fig. 2. Fig. 5 represents an enlarged sectional detail of one of the tubes and its connecting member forming one of the sections of the vertical standpipe, the cutting plane on line 55 on Fig. 4, and Fig. 6 represents an enlarged section through one of the tubes, the cutting plane being on line 6-6 on Fig. 4c.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 pit of a boiler above which is located the usual grate 11. Access to the fire-pot 12 is provided through the fire door 13. Above the fire-pot 12 are located a plurality of double-walled tubes 14, the opposite ends of which are connected in a novel manner to the standpipes l5 and 16, respectively, at the front and rear ends of the boiler.

The vertical standpipe 16 communicates with a chamber 1'? in the rear of the boiler connected by a pipe 18 to the annular passage 19 formed between the cylinder 20 and the inner tubular member 21 concentrically located therein, the ends of the passage 19 being closed by the annular members 22 interposed between said members 20 and 21 as clearly indicated in Fig. 1 of the drawings.

The passage 19 is connected at its opposite end by means of a pipe 23 with an inlet pipe 24. All of the front standpipes l5 connect with a horizontal pipe 25 from which extends a pipe 26 communicating with a steam drum 27. The products of combustion pass upwardly from the fire-pot in the direction of the arrows on Fig. 1 and through the pipe 21 and around and along the outer surface of the pipe 20. The products of combustion passing through the pipe 21 are forced by means of the aspirator 28 through the pipe 29 into the reservoir where any soot or unconsumed matter is collected, the gas itself passing outward from said reservoir through the pipe 31.

The vertical standpipes 15 are composed of a plurality of T-shaped members 32 each member having a lateral branch 83, one wall of which is threaded to receive the end of a pipe 34 forming one wall of a tube 14: while a smaller. longer pipe concentrically disposed within the pipe 34 is reamed or otherwise fitted to the opposite wall 36 of said branch 33. as indicated clearly in Fig. 4: of the drawings. These pipes 34: and 3 5 thus centrally disposed relative to each other form an annular passage 37 communicating at either end with the passage 38 within the T-shaped member, said passage 38 in turn communicating with the vertical passage 39 extending therethrough. Each end of the pipe 35 is open and the products of combustion passing from the fire-pot 12 are free to pass through the interior of this pipe and also around the exterior surface of the pipe 3 1. By this means the water circulatrepresents the ashing through the passage 37 is subjected to a greatly increased heating surface, which obviously is of a great advantage.

The upper ends of the Vertical standpipes are connected to the horizontal pipe 25, as indicated clearly in i 2 of the drawings. lletween the branch oi the pipe and the end of the 't shaped member 33 is a ring 4-1 having both ends tapered to fit ,within the ends of the branch it) and the T- shaped member Similar rings are interposed between the various 'l shaped members 32 while the end opposite to the horizontal pipe is provided with header l 9.

it rod t3 extends centrally through the various rings 4:1, members 32, header through a wall oi the pipe 25, threaded to cit-her end of said rod serving a means (till locking all the Various lions together to secure a tight joint.

The rear vertical standpipe ll; is similarly constructed and connected to the horizontal chamber 17. The ln'anches ot each of the T-shaped members are so constructed relative to the vertical portions of said members that the inner pipe 35 of each tube ma be withd awn without disconnectin; the sec tions from the ort r pipe member 3n.

Qecurcd to the ,v pcd members by means oi bo ts to are a plurality of: removable plates 46 at the front; and rear oi? the boiler by removing which access may be readily obtained to any particular stack oi tubes for the purpose of withdrawing an in i and nuts ell l l l l l l l ner pipe member 35 and replacing it when desired.

The advantages of con tructing a boiler in this manner whereby the heating surface of the Various tubes doubled is Very apparent and it is believed that in ties of this the invention will be thoroughly understood without "further description.

Having thus described my invention, I claim:

1. In an apparatus of the class described, the combination of two standpipes each composed ot' a pluralit 0t l membcrs .ovided with lateral branches each of less depth than the bod portion of said members; a pipe extending through and connecting two of said brai'iches; and a sccmnl pipe surrounding the tirstanentioned pipe and also connected to said branches ann forming an annular passage communicating with the iuterior oi. both standpipes.
