A. H. WILLETT FLUE SNDING APPARATUS FOR LOCOMOTIVE FIRE BOXES Filed sept. 2., 1919 2 Sheets-Sheet 2 WITNESS:
' INVENTOR A TTORNEYS handle 14 being actuated lto admit air under pressure carrying sand in suspension through the pipe 9 through the elbow 10 and outlet nozzle 11, a stream of sand will be violently projected toward the flue sheet as shown by the dotted line 20, and over the whole sur face of the ends of the flues and eectively clean off any soot or other objectionable formation which may tend to choke up the coming from the-sides.
Still another arrangement is shown in Figure 4 in which, at 23 I have indicated a special formation of block which' has the sand pipe connected therewith from undeu neath, and with which there is no refractory wall or partition employed. Owing to the location of the sanding device in the front of the Acombustion space, in much the same relation to the flue sheet as in Figs. 1 and 3, ready access of the sand blast to the flue sheet is secured.
IVhile it -will be observed that in the arrangement shown in Figures 1, 2 and 4, the sand supply pipe comes up from underneath, it may be expedient in some instances to bring the sand supply pipe in through the side walls of the fire box, and such arrangement I have shown in detail in Figures 5, 6 and 7 in which there is a pipe 24 coming in from each side of the re box toward the center, each of said pipes being provided with a plurality of nozzles 25 opening through apertures 26` in the side of the corner brick of the refractory arch and Gaines wall structure (which structure is otherwise just about like that of Fig. 1).
In the several constructions illustrated, it will be seen, the forward and upward-discharging sanding device is sheltered and protected by the refractory structure behind and above it (and especially by the brick or block 21 and 28 in Figs. 3 and 4) from the hot furnace gases passing or sweeping forward to the boiler fines.
I claim:
1. lThe combination with a locomotive fire box and a refractory structure obstructing the same behind the iiue sheet and lues, of sanding means for them protected in said refractory structure and discharging forward therefrom.
2. The combination with a locomotive boiler fire box and a refractory structure in its lower forward' portion, of a sanding de vice discharging forward and upward upon the boiler flue sheet sheltered and protected by said refractory structure from the forward-sweeping furnace gases on their way to the boiler flues.
In testimony whereof I have signed my name.
ALFRED II. VILLETT.
