'rE- STATES RAFFLE SUPPORT FOR WATER-TUBE'BOILERS.

Application filed December 23, 1921. Serial No. 524,448.

To all whom it mag concern;

Be it known that I WILLIAM J. STOOP, a

citizen of the United tates of America, and

resident of Wheeling, county of Ohio, State of West Virginia, have invented certain new and useful Improvements in Baflle Supports for Water-Tube Boilers, of which the following is a specification. v

This invention relates broadly to waterm tube boilers of the Stirling type, and more specifically to means for supporting'the baffie walls of such boilers.

The primary object of the invention is to provide, in a water-tube boiler, a simple and as improved means of support for the usual baflle walls whereby the passage of the heated gases and products of combustion are guided and deflected in their course with respect to the tubes; I v

As boilers of this type have heretofore been constructed, it has been the practically universal practice to support certain of the baflie walls by resting the lower ends thereof upon clamps attached at suitable points to at certain of the boiler tubes. Theseclamps are objectionable as supports for various reasons, chief among which may be mentioned that, due to the expansion andcontraction which results from wide variations of temao perature to which they are subjected, said clamps work loose and shift out of position to the extent that it is ractically impossible to maintain them'in t eir normal horizontally alined relation for any considerable as length of time.

It is the aim of the present invention to providea form of mounting which will serve to permanently support the baffle walls in their proper positions.

In describing the invention in detail,-reference is herein had to the accompanying drawings, in which-- Figure 1 is a longitudinal section of a boiler equipped with my invention; and

Figure 2 is a transverse section of the same taken substantially on line 2-2, Fig. l, with the boiler tubes and bafiies omitted to more clearly illustrate my invention.

Referring to said drawings, 1 and 2 indie at cate, respectively, thesecond and third banks. of tubes of the boiler, and 8 and 4 designate bafiies or baflie walls associated with said banks for guiding and deflecting the course of the gases'and products of combustion with respect to said banks in their passlsatgg from the furnace 5 to the stack-oute v Each of said baflles 3 and 4 rests in an incl ned position against certain rows of the tubes in said banks 1 and 2 and has its lower end seated upon a transversely disposed horizontal member 7 which may be in the form of a bar or rod, but is preferably in the form of a metal pipe, as shown. Each pipe 7 is suspended intermediate its ends by one or more metal rods 8 which have terminal books or eyes 9 formed on their lower ends, said hooks or eyes being disposed in embracing relation tosaid pipe. Said rods 8 depend from a suitable overhanging support, such support being preferably constituted by parallel I-beams 10 upon which is carried, as ordinarily, the usual cross-bafiie 11. It will be understood that other forms of support for the rods may be employed and that, therefore, I do not desire to confine myself exclusively to the use of the I-beam support shown, which latter is preferred simply for the reason that it is conveniently located for-the purpose and its use avoids the necessity of introducing other means of sup ort for said rods.

T e upper ends of the rods 8 are threaded and directed through short plates or channel sections 12 which are interposed between the I-beams 10 with their opposite ends seated upon the adjacent base flanges of said I-beams. Nuts 13 threaded upon said rods rest upon said plates 12 for supporting the rods, as shown.

It is preferred that pipes, rather than rods, constitute the baflle seating members 7 and also that the opposite ends of said pipes be extended outward through the side walls 14 of the boiler, thus permitting cool air to circulate through the pipes for coolingvpurposes.

. hat is claimed is- '1. In a water-tube boiler, the combination with an inclined baflie for uiding and deflecting the products of com ustion with respect to the banks of water-tubes, of a mounting for said bafile comprising a horizontally disposed pipe arranged in underlying supporting relation to the lower end of sa1d ba-file, said pipe having its ends opening outward throug the side walls of the boiler, and suspension rods by which said pipe is carried, said rods being attached to a stationary supporting member occupying an elevated position within the boiler.

2. In a water-tube boiler, the combination with inclined bafiies for guiding and deflecting the products of combustion with respect to the banks of water tubes, and I-beam supports for a cross-baflie, of supporting means for said inclined baflies, said means com rising horizontally disposed pipes upon W ich the lower ends of said baffles are seated, said pipes having their opposite ends projecting outward through the side walls of the boiler,

- and suspension rods depending fromsaid I- beam supports and having their lower ends in supporting relation to said pipes.

3. In a water-tube boiler, the combination with inclined baflies for iding and deflecting. the products of com ustion with respect to the banks of water tubes, and I- bea-m supports for a cross-ba-fiie, of supporting means for said inclined baffles, said means comprising horizontally disposed pipes upon which the lower ends of said bafiies are seated, said pipes having their opposite ends projecting outward through the side walls of the boiler, and suspension rods depending from said'I-beam supports, said rods having eyes formed on their lower ends and having said pipes directed through said eyes In testimony whereof, I aflix my signature in presence of two subscribing witnesses.
