BOILER BAFFLE.
Application led .Tune 4,
My invention relates to the construction of baflles used in boilers, and will be understood by reference t0 the accompanying drawings in which Figure l is a side view of a portion of two banks of tubes of a water tube boiler with the baflle in section and with spacing strips in place before pouring the plastic material; Fig. 2 a view similar to Fig. l with the spacing strips removed and the baffle ready for pouring; Fig. 3 a similar view of the baffleas completed after pouring; and Figli avertical section on the plane of the line 4-4c of Fig. l. Similar reference numerals indicate similar parts in the several views. l
Referring to the drawingsthe numeral l designates a portion of the tubes of a water tube boiler the tubes being arranged in two groups or banks. It has been customary to build the baffles, of this typev of boiler, of walls of tiling and cast iron flame plates resting upon the tubes. I have retained this general character of baffling but have separated the walls of tiling and interposed be-l tween them a wall of poured plastic material and also, where desired or necessary, a wall of plastic material between the flame plate and one of the walls of tiling. The tubes are shown as divided into two banks with an interposed wall of fire brick 2 resting upon the upper row of tubes of the lower bank. The lower part of the baffle, as shown, rises from the bridge wall 3. In the practice of my invention I proceed as follows I build up the two walls 4 and 5 of the usual tile blocks fitted around and supported upon the boiler tubes, with spacing strips 6 between them and with the tiling braced by wood cross pieces 7 held in place by blocks 8 forced between them and the tubes. The baille also comprises a flame plate 9 made up, as usual, of inner and outer cast iron plates with asbestos plates between them, spacing strips 6 being placed between the lower flame plate and the inner lower wall 5. A permanent retaining cross piece 10 comes between the upper and lower sections of the flame plates and holds the ends of". the pieces which make up the flame plates, in alignment. The upper flame plate is held at its upper end bv corrugated backing bars l2 which bars are in turn held by tube clamps 13. The lower flame plate 9 is held at its lower end by the Z-bar 11 and by corrugated 191s. semina. 238,097.
lith the parts arranged and built up as l shown in Fig. l, I Ythen remove the spacing` strips 6, as shown in Fig. 2, and pour the form so prepared with anyv suitable grouting to fill the space between the walls 4L and 5,
and that between the lower-wall 5 and the lower flame plate 9, as indicated in Fig. 3. lVhen the grouting isset, the braces Tand 8 are removed.
For the grouting I have used a mixture of finely ground fire brick, asbestos fibre, Portland cement and fire clay. The particular grouting used, however, may be varied to suit particular conditions and the proportions of the ingredients be changed as desired. For the initial pouring the grouting should be of relatively thin consistency so that it may find its way to the bottom of the spaces between theJ lower walls of tiling and the flame plate. The use of asbestos in the mixture is of advantage in that the fibre closes the cracks and assists in preventing an undue amount of leakage of the plastic material when being poured.
Various modifications may be made in the baflle as described, as, for example, the present method may be employed for constructing al baffle one side only of which is faced with refractory tiling; for example in Figure 1, the line of tiling 5 `may be omitted,
and the entire space between the line of tiling 4. and the flame plates 9, filled in with poured plastic material. Again, if' desired, the flame plates 9 may be removed after the plastic material has set, and the resulting baffle will then consist of a baille, one side of which is faced with refractory tiling, and the body of which is of material, which, before itis placed in position and becomes set and hardened, is in a plastic state.
What I claim and desire to secure by Letters Patent of the United States is l. A baffle for water tube boilers consisting of two separated walls extending across and surrounding the tubes, each of said walls'comprising a plurality of tiles at least partly in contact with and resting on the water tubes to torni a substantially closed side of a mold, each tile being less in Width and height than the width and height of Athe baiiie and a layer of poured and hardened plastic material between and held by said side walls.
2. A baiile for water tube boilers consists ing of two separated walls extending across and surrounding the tubes, yeach of said walls comprising a plurality ot tiles at least partly in contact with and resting on the water tubes to forni a substantially closed side of a mold, `each tile being less in width and height than the width and baille, and a layer of hardened plastic material between and held by said side walls, said plastic material containing yfibrous matter.
4. A baille tor Water tube boilers consisting of two separated walls extending across and surrounding the tubes, each of said'walls comprising a Vplurality of tiles at least partly in contact with and resting on the water tubes to torni a substantially closed side of a mold, each tile being less in width and height than the Width and height of the battle, a layer ot hardened plastic material between and held by said side walls, and a separate tile between each pair `off tubes in each horizontal row, said plastic material containing fibrous matter.
