F''EL-DISTRIBUTER.

-LSQLYQ Application filed une i9,

To all 'whom 'it may concern.'

Be it known that l, NATHANv M. Lownn, a citizen of the llnited States, and residentot Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and uset'ul linproveinents `in Fuel-Distributers, of which the following is a speeitication, and which are illustrated in the ac-y companying drawings, forming a part thereof.

rlhe invention relates to device-s used in connection with mechanical stokers for distributing fuel, such as coal, within a lirebox; its object beingr to provide for the even distribution 0i the fuel over-the grate.

The invention consists of a tubular body having an open end and adv'apted to be; horizontally positioned Within the hre-box wall, and being provided With nozzles at its inner end adapted to discharge jets of luid, such as steam or air, obliquely backward tor the purpose ot detlecting` a portion of the fuel impelled through the tube by any suitable means to` spread it upon the grate at the end of the lire-box at which thedistributer is located, and especially to insure the deposit oi' an ample supply of fuel upon the corners ot the grate; such nozzles being located at the top or bot-tom ot the tube, or

at both ot these positions.

In the drawings showing` e preferred torni of construction- Figure l is a plan view ot a distributor;

Fig. 2 isl a longitudinal vertical section, partly in elevation; and

Fig. 3 is a rear end view thereof.

The distributor preferably takes the form of a. tube 29, having a fiat bottoni 30 and being adapted to be secured within an opening in the Wall of the lire-box, there being; shown as a convenient means for such attachment an aperture 3l in. the upper portion ot' the tube adjacent its rear end Within which a retaining hook may be engaged.

The tube 29 is open at its inner end to permit theiree discharge of fuel inipelled therethrough by any preferred ineens, and in the embodimentshown is also open at its rear end to receive the fuel from any suit able sourcebt' supply, suoli as an elevator or a hopper, thougli itis immaterial to the present invention "whether, the receiving opening be at'the end or laterally.

At the forward, end of the tube 29 there is a forwardly extending tia-nge 82, preter- Specification of Letters Patent. PatQni-e Sept. 27, 1921.

ably formed integral with the body, as shown, the lower face of this flange being given any desired conlivuration but is prel erably dat, as shown. portion of the fuel which may be impelled through 'the tube at considerable velocity will strike thevunder face of the flange 32, and be thereby directed downwardly' and scatteredover a zone ot'A considerable width.

.Depending from the flange 32 is a nozzle 33, here shown as in the forznof a hollow integral boss, this nozzle being provided with a. plurality of discharge openings, as 34, which are directed backwardly' and downwardly, and some of theni oblique to the direction in which the fuel is advanced through the tube. Fluid under pressure is supplied to the nozzle 33 through a suitable duct 35, which in the disclosed form of construction is cored in the top'wall of the tube. there being provided a suitable opening at which a service pipe may be attached.- For this letter purpose there is` shown such openings at 36, 37, and 38, any or all of which may be used.

A similar nozzle 39 issecured at the for; ward end ot the bottom the tube. If de;- sired, this nozzle may tale the form' of au. elbow nipple, as shown,"screwed `into the end ot' the tube 29 to 'communicate with a cored duct 4:0," supplied with fluid under pressure through suitable pipes connected with its reni* end, as at il or 42. Whatever may be its specific forni the nozzle 39 projects upwardly, above the floor or bottom 30 oi the tube 2S), and is provided with a plu` rulity ot laterally bcluvurdly directed openings, as 43, adapted to discharge fluid jets which will dcliect. portions of the dvancing i'uel vto the corners ot the fireoX. i

Various embodiments ot the invention moy be made which will come within its scope, the essential feature of which is the location ot the scattering jetsat' the inner end of a fuel induction passage.

l clainius .my invention- 1. ln a fuel distributer, an open ended tube adapted to be disposed in a substantially horizontal position and through which fuel may be ilnpelled, und a fluid-discharging nozzle at the upper side of the forward end of the tube and having its outlet ports backwardly and downwardly directed'.

2. ln e fuel distributor, an open ended tube adapted to he disposed in a substantially horizontal position and through which fuel may be impelled, and a fluid discharging` nozzle at the upper side of the l'orward end of: the tube and having its outlet ports backwardly, downwardly and laterally directed.

3. A distrihuter tube having` a lat bottom and an open discharge end and adapted to be horizontally positioned and having a flange projecting` from the upper portion of its discharge end, a fluid nozzle projecting' upward at the forward end of its bottom and discharging obliquely backward1 and a fluid nozzle depending from the flange and disA charging haclnvardly.

4. A distributor tube having a flat bottoni and an open discharge end and ada pted to be horizontally positioned and havingl a flange projectingl from the upper portion of its discharge end, a fluid nozzleprojecting upward at the forward end oi its bottom and disnsem v charging obliquely backward, and a fluid nozzle depending from the llange and discharging obliquely backward.

A'luel distributor comprisingr a passage through which fuel may be impelled, and vla fluid discharging nozzle located at the inner end of the passage and adjacent its upper portion and l'iaving jet openings directed obliquely baclm'ard. l

A fuel distributor coniprisinga passage through which fuel may be impelled, anda fluid nozzle located beyond the delivery end of the passage and having jet openings directed obliquely backward.

T. A fuel distributor comprisingr a passage through which fuel may be impelled, 4and a fluid nozzle 'located beyond the delivery endj of the passage and depending into the line lofthe path ol fuel iinpelled through such )assafe and havino v'et oieninefs directed Pi l ohliquely backward.
