NEW YORK Y or N WYQRK, N. Y., A oonPoRnTIoN or PULVERIZED COAL DISTRIBUTOR Application fiied'ianuar ee, 1926. Serial No. 34,747.

provide an improved means whereby a stream of such material as pulverized coal may be uniformly and efiecti'vely distributed between 7 several branches. As illustrative of this object it is customary, in the burning of pulverized coal, to employ a plurality of burners,

the coal being supplied to said burners I through pipes branching from a main conduit 1 or supply line. Uniformity of feed and relativeequality of distribution is highly desirable, and this is accomplished by means of my invention. V V

More specifically it is an'object of my in-. vention to provide a distributor which is of simple construction and easy and inexpensiv to manufacture. V v

The foregoi1ig,together with such other objects as may hereinafter appear, or are incident to my invention, are realized by ,a construction which I have illustrated in the preferred form in the accompanying drawings, wherein- Fig. 1 is a section taken through mydi'stributor mechanism on the line 1-1 of Fig. 2.

Fig. 2 is a partial section andside elevation of Fig. 1, the section being taken on theline 22 of Fig. 1. p 4 p I 3 is a perspective view showing a num-' ber of the distributing elements employed carrying out my invention. 7

Referring now to F igs. 1 and 2, the reference character 7 denotes a tubular coupling member or throat adapted to be, connected to the main supply conduit not shown. At-

tached'to the member 7 is a Y or other forked member 8, the legs 9 of which are adapted to be connected to the branch pipes (not shown) leading to the burners orother points, as the case may be. At each of two opposite sides the upper portion of themeinber 8 has inwardly projecting lips or ribs 10 from which the distributor elements '11 are suspended.

These distributor elements 11 are counter.

parts of one another. 'Theyare triangularshaped, andcomprise a side Wall portion and an end Wall portion 13 having at its up- '-per edgeashoulder. 14 adapted to rest upon one of the ribs 10. At the opposite upper corner there is a-spacer lug 15 projecting from thesidewall 12 andserving'as a means for suspe'nding'the distributor element from the other rib 10 of the member 8. When the elements ar,e assembled in alternately reversed relation,t hey cooperate to provide oppositely incl ned chutes or channels alternately directing coal tothe branches 9 of the member ,8. The effect ofthe distributors is to split up the main stream of coal into a plu rality of smaller streams, and certain of these smaller streams are directed into one branch 9. and the remainder into theother branch .9. The smaller. streams. delivered toeach branch reunite-into a single stream. This produces whatlmayfbe termed a reconditioning of the 'coal, i n which connection it is .to be understood that the coalis transported through the medium of'the air, i. e., the material delivered to the distributor is almixture of "coal and air.

' This reconditioning produces a uniform state of themixture of coal, and air in thebranches,

and the construction and disposition, of the d stributor elements secures an approximate ly uniform distribution as between the branches. While Ihave shown the distributor as comprising six dlstributor elements, the number thereof may be increased or decreasedby relatively decreasing or increas.
