WATER TUBE BOILER.

Mme/Mk -i'nents in ater-Tube Boilers, of which the UNITED STATES PATENT orncs.
rmuvs mARnvUs MEYER, or AMSTERDAM, N THERLANDS,
To all whom it may concern:
. Be it known that I, FRaNs MARINUS- LTEYER, residing in Amsterdam, lste Helmerstraat No. 238, subject ofNetherlands, have invented certain new and useful Improvefollowi'iig is a specification.
Thisj invention relates to Water tube boil-.
ers, and the object thereof is to improve the construction of water-tub'e-steam boilers and particularly to provide a simple and cheap construction andat the. same time to provide means for preventing leakage at the different joints between the tubes, headers or boxes and steam drum. lVith this object in viewthe. invention consists in a water-tubeboi-lenfwherein the front and back-headers are connected by means of bent or curved water-tubes welded to said headers, said headers being attached 'to the steam-drum by means of movable and adjustable connections in such a manner that the headers and water-tubes are able to expand freely and independently of the steam-drum. I r
The invention further consists in a watertube boiler wherein the front-headers are separately movable and adjustable relatively to the steam-drum, while the back-headers are collectively movable and adjustable relatively to the drum.
A T-shaped steam and water-drum is employed in conjunction with' a number of front and back-headers or boxes, the 'front and back-headers being connected to each other by a bank or" bent or curved watertubes, WlllCll are welded to the headers.
Each front header is connected to the transverse portion of the drum bymeans of a hollow fitting with adjustable and movable conical or ball connections, the back-headers being coupled by means of common flanges to a horizontal collecting tube or mud-drum, the latter being at each end connected to the steam-drum by means of a vertical tube having two adjustable and movable conical or ball connections.
Contrary to the existing types of water tube boilers, boilers constructed according to the present invention may be constructed very cheaply, on account of the simple and durable connection of the water-tubes and headers. Again the inconvenience of leakage w1ll be reduced to a ,maxlmum, s1nce welded connections are less likely to leak than screwed or rolled ones, and moreover,

Application filed April 19, 1919.: Serial No.29 1,279. 1
This feature, in connection with the.
curved 1 1m. of the water-tubes, allows .a free and independent expansion -of the'variouspartsand avolds-dang'erous stresses in the parts of the apparatus and also leakages and; other inconveniences.
The boiler may be easilytaken to'pieces H and assembled afterwardvery rapidly, (but little sk lled assistanc'ejsbeing required; A constructional form of aa boiler according theginve'ntion" is shown.-i'I 1,the'=accom-;:

Figure 1 is a side View of a welded Watertube boiler;
Fig. 2 is a sectional view taken on the line 22 of Fig. 1.
Fig. 3 is a top view of a welded watertube boiler; Fig; 4 is a front View of a welded watertube boiler;
Fig. 5 is a partial sectional elevation of a connection between the steam header and each water-tube element separately;
Fig. 6 1s a detail section of amovable connection between the steam drum and the movable connection of the water-tube ele-' ments. Fig. 7 is a side view-of a water-tube element.
The improved water-tube boiler comprises a T-shaped'steam-drum 1, riveted in the usual way and which may be fitted with a steam-dome 2 and 3 is a cross-tube riveted tothe rear part of the steam-drum. 4 are tubes 4 are fitted adjacent their ends with flanges 4' against which bear rings 10. Suitable bolts-10, connect the flanges 9 and rings 10 and maintain the surfaces 7 and 8 in steam-tight contact and permit of adjustment of the joint. The back-headers 14, are attached to the mud-drum 11 by any 'vertical tubes which are connected at 5 to the crosstube 3, and at6 to the horizontal list transverse portion of the T-shaped steam-r drum 3 by means of the fittings shown in Fi 5. These fittings each consists of a ho ow nipple 16, having a conical upper portion adapted to fit in a conical opening of the steam-drum, and a curved lower portion adapted to fit in a correspondingly curved seat formed in the end of the head-' ers 15. The upper and lower parts of the nipples 16 are caused; to make steam-tight contact with their seats by means of the bolt 17 The bolt 17 issecured atthe lower end through an eye in a brace 18. A nutendto the header 15 and passes at its upper 19 on the end of the bolt 17 and bearing a on the brace 18, maintains the nipple 16 in steam-tight fengagement withits seats, and permitsadjustment of the joint.
The steam-drum 1 is suspended toward the rear by a strap 20, in order to allow said drum to expand freely.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed,rI declare that what I claim is:
In a watertube-boiler consisting of a steam drum, front and backheaders' and muddrum, and'the headers connected to each other by means of bent watertubes welded to said headers, said steamdrumbeing of T-configuration, the front headers being separately andmovably connected to the cross-leg of the T-shaped steamdrum, the said backheaders being each connected to the muddrum, the latter being movably connected to the other leg of said T-shaped steamdrum. V
'In testimony that I'claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
I FRANS MARINUS MEYER.
