WATER-TUBE BOILER .To all whom it may concern.

Be it known that I, HARRY F. BASCOM, a citizen of the United States, residing at Allentown, in the county of Leh1 h and State of Pennsylvania, have invente a new and useful Water-Tube Boiler, of which the followin is a specification.

It is t e object of this invent-ion to provide a means whereby access may be had to a boiler structure, for the purpose of cleaning the tubes and the drums thereof, without interfering with the circulation of products of combustion about the tubes and the drums.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that chan es in the precise embodiment of invention erein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 is a front elevation of a fragment of an end wall of a boiler, equipped with the device of my invention; Fig. 2 is a rear elevation of a fragment of an end wall of a boiler structure, equipped with the device of my invention, the mud drum being shown in section, and the partition which is above the mud drum being sectioned also, the artition being broken away at its lower e ge, in order to disclose a removable plate which constitutes a portion of the invention. Fi 3 shows the invention in perspective, an Fig. 4 is a vertical section transversely of the end wall of the boiler, the view showing the manner in which the invention is mounted, and how the invention cooperates with the partition and the drum of the boiler.

The device forming the subject matter of this application, is adapted to be employed in connection with boilers of widely difi'erent types, but, in order to present a concrete embodiment, 'I- have ap. lied the device to one particular type of oiler, namely, the Sterling boiler, so called, without, of course, limiting the use of the invention to this particular form of boiler.

The particular boiler undr consideration, consists of a plurality of upper drums (not shown) united by means of tubes 1 and 2, with .a lower drum 3, known as the muddrum. The end wall of the inclosing strucflpeclfloatton of hotter: Patent.

ture for the boiler, is denote by the numeral 4, and in lateral abutment with the end Wall 4, is an upright partition 5, and this partition, as clearly shown in Fi 4 extends downwardly into abutment with the drum 3.

Referring to Fig. 2, and noting the arrows therein, it will be understood that the products of combustion, in this articular type of boiler, move transversely of the boiler structure, about the tubes 2, into contact with the partition 5, the products of combustion passing thence, over the top of the partition 5, and downwardly along the opposite side of the partition, about the tubes 1.

By way of explanation I will state that in boilers generally, and in the type of boiler shown, 1n particular, the efficiency of the boiler is decreased, by reason of the fact that dust and other foreign matter accumulates about the tubes 1 and 2 in the vicinity of the drums, particularly in the vicinity of the lower mud-drum 3. This invention aims to provide means whereby access may be had readily to a boiler drum, and to the tubes of the boiler, for the purpose of cleanin same, the device, however, normally interfering in no wise with the circulation of products of combustion about the drums and the tubes. In carrying out the invention, then, an opening is fashioned in the end wall 4 of the boiler structure, above the drum 3. Into this opening is inserted a box-like casing 6, open at its forward and rear ends. The articular form given to this casing, may e varied, but the specific casing shown most clearly in Fig. 3, will be found convenient to use, and inexpensive to manufacture. In its forward edge, the casing 6 is supplied with a plurality of outstanding lugs 7, adapted to extend through a closure 8. Wing nuts 9, or other securin elements adapted to a like end, are mounte upon the lugs 7, to hold the closure in place. At any convenient point in the closure 8, there is an opening 10 (see Fig. 4) this opening being normally closed by means of a door 11 which, if desired, may be pivoted in its uppermost portion to the closure 8, as shown at 12. One of the lugs which outstands from the forward edge of the casing 6, in the present instance, the lug denoted specifically by the numeral 14, carries tail-nut 15, adapted to engage the door 11 to hold the same in closed position.

Extended longitudinally of the casing 6,

RBI SUED the upon its top, is a reinforcing'flange 16, the

the tubes 1 and 2 is desired, the door 11 maybe opened. If a thorough cleaning of the tubes and the drum is found to be necessary, the wing nuts 9 may be removed, permitting the closure 8 to be set aside, whereupon the plate 18 may be withdrawn from the guides 17, thus giving easy access to the tubes and the d rum.

The plate 18, when mounted in the guides 17, abuts against the forward end of the partition 5. The reason why the plate 18 is provided, will be clearly understood from an inspection of Figs. 2 and 3.

Noting, at present, Fig. 3, it will be seen that,;in the absence of the plate 18, the products of combustion, following the arrows in Fig. 3,

would pass intothe casing 6, laterally around the forward edge of the partition.

5, thus putting an end to the circulation upon the opposite sides of the partition, 5, as shown by the arrows in Fig. 2. When the plate is in terminal abutment with the partition 5, as shown in Fig. 4, it will be seen that the closure 8 serves as a means for holding the plate 18 in place. Obviously, the removal of the plate 18' permits the operator to examine and to clean the tubes which are located upon opposite sides of the partition 5.

Although, in Fig. 4, the casing 6 is shown as not-extending entirely through the end wall 1, and although in Fig. 3, the plate 18 protrudes inwardly beyond the casing 6, it will be readily understood that these details may be altered, so that the casing 6, the plate 18, the end wall 4, and the partition 5, will all cooperate to give the desired access to the tubes and the drum, without interfering with the circulation of the products of combustion through the ture.

boiler strucoa er? It is to ,be noted, that the improvement herein disclosed, isadapted not only for the purposes of cleaning the drums and the tubes, but, as well, for determining, by inspection, whether any of the tubes are leaking or broken. p

Having thus described the invention, what is claimed is 1. In a device of the class described, an.

end Wall having an opening; a partition extended across the opening and abutting against the Wall;.an imperforate plate removably held in the openin longitudinally of the, opening andinterme iate the sides of the opening, the plate abutting-against the partition to prevent a {cross draft through the opening; and a closure for the outer end of the opening, with which closure the plate engages.

2. In a device of the class described, an

drum and having an opening; a partition in abutmentwith the end wall and the drum; a casing adapted to be inserted into the opening in the end wall, the opening and the casing being extended beyond both sides of the partition; a plate insertible into the casing, to abut against the partition and to prevent acrossdraftthrough the opening; and a removable closure for the easing, serving at once to give access to the casing,and asa means for holding the plate in abutment with the partition.

In-testimony that I claim the foregoing as my own, I have hereto afixed my signature in the presence ,of two witnesses.
