` To @ZZ to from t may concern Be it lknown thatnllfiinnr l". blomus, a citizen oi' the United States, residing at Collingswood, in the county of Camden and State of New, Jersey, has invented certain new and useful lmprovements in Furnace 'frates, oi which lication. y

'.i'fhis invention relates to improvements in forced and natural dralft water gratos.

The `principal object ot the invention is to provide moans to obtain a horizontal dralt iu a grate cit the elv `described whereby the liner rudes ot iuel will not be disturbed, as in A provided with u direct upward draft, and the same is an improvement on Letters Patent No. 1.261,268

issued to myself and Bitner Shinn, April y 2, i918; lLetters Patent No. 1,348,235 granted to myself under detect August 3, 1920 and an application ytor Letters Patent :tiled by me March 1921, bearing Serial Number 449,524;

A further object of. the invention is to simplify the meansot passing air through the vgrate and to` control `the quantity of such air, in` order-to obtain the proper combustion oi:l the VJfuel on saidgrate under any und all conditions. i f

'A further object ofthe invention is to provide communicating means between the cored openings inv the grate `and the surface ot' .nid grate, whereby the volume ot' air to be distributed'orer the grate'surfaoe may be exactly regulated. f

ln carry' g out the above stated, an other, objet-ts I providea device of new and `novel construction whereby the ascending draft oi1 air thru the cored vertical openings in said grate is deflected and distributed yhorizontally over the surface of the grate, the air openings thru which the air is distributed being so` constructed `and arranged that the air loses its torce or v.f'ioleuoe before the distribution thereof takes place and the unionot the air forces at the point where the air leaves the discsis prevented,obviat ing a multiplicity ot' openings with an upn'ard draft which cause a lifting and disturbance oit` the fuel, detrimental to the burning thereof where coa-l dirt andthe finer grades ol fuel are used and causes the tubes, combustion chamber and chimney to ill with unoonsumed particles of said fuel. This result l" iind in i practice is` absolutely 'prevented by the use of my indirect horithe following is a vs )eci- 1921. serial No. 461,491.

zontal side distribution of the airyinore air y, and more pressure can thus be l exerted against small iuel than by any other known method and poorer grades ot' uel maybe burned faster `and a more tion had thereof` perfect combuslJVhere the ascending air from the cored openings in the grate is admitted directly vertically to the fuel bed the said air will leavesaid openings in jets, with more or f less 'force or violence, according to the pressure there luel.

Referring tothe Adrawings in detail the.` numeral l0 designates a lire grate `provided at the :front with aqwater inlet pipe ll whereby water 12 enters and circulates thru said grate l0.

A. water outletpipe 13 provided at the back of said grate'lO Whereby .the water after circulating` through said grate and being subjected to the heat therein is carriedoff, thus providing for a continuous circulation of the water through said grate` preventing the overheating andk melting` thereof.

T he water 4flow and return pipes ll and t3, respectively, are connected with the boiler,

water tank or other source ot `supply. y

An air chamber '14: is provided having the door l5 tor access thereto `and a latohl to 'secure the same'iin a closed position.

'This door ihowever., ma be secured by means ot' a bolt or other suitable means asy will insure, as near as connection.

possible, an air tight To obtain forced draft air is forced` by a blower or other suitable means, through the pipe l into and thru the air chamber.lal

discs vtical cored opening-s or holes 18, aforesaid,y

and the top o' said grate 1,0 is provided with the sunken grooves or channels 22. rlhe sunken grooves 22, substantially oblong in orin, radiate horizontally `from the cored openings 18 in said grate l0. ln said cored openings 18, through Which air is admitted to the grate l0, from the air chamber il, metal discs 19 are positioned, said discs i9 being tapering orconical in form, as particularly illustrated in Fig. oit' the drawings, to fit Within said `openings 18, and provided with heads 2l, sealing the dire-rt or vertical. outletsfof the openings 18.

'The said discs 19 are provided with flanged heads 2l and beneath said heads are provided with vertical tapering grooves 2O adapted to communicate with the grooves 22 inthe upper surface of the grate 'l0 radiating from the cored openings i8, whereby said heads 2l act as deflectors el the air travellingup the openings 18 from the air chamber lll, thereby vcausing said air to travel through the vertical grooves 52,0 and then horizontally through the grooves 22 along the upper surface or'. the grate l0, in-

stead of directly upwardly and vertically as inl theinvention hereinbeicore cited; the heads 21 closing vthe vertical outlets of the openings '18. l

l have illustrated in the drawings tive vertical grooves and live horizontal grooves 22. These various gii'ooves may be or' such numberfas .may be found requisiteilor the purposes herein stated. v

lt Will benoted that the grooves 22 are "for air travel under the lire bed and are so positioned that the air travelling throughone groove' does not communicate directly or gain admission to any o'tiier groove radiating :from the same orv other cored opening 18.

The discs 19 by a slight rotary movement thereof will regulate the amount of vair to be -nieate therewith.

admitted to the grooves Edin the grate lll 4trein the openings 18; permitting the 'full volume of the vair ascending through said ope1'nns 18 to pass to the grooves 20 1t the groove-s 22in the said discsV 'i9 fully coinmurl`his meansv ot' control of the volume ot air to be admitted to the grate by the communicating grooves 20 and 22 is particularly illustrated in Fig. 3 of the drawings.

Although in the drawings l have shown certain details of construction and in the preceding, have described such details, it is obvious that l need not be limited thereto other-Wise than to the extent to which the appended claims restrict me.

llavingthus described. my inventionwhat l claim as new and desire to secure by Letters Patent is f l. ln a grate ot the class described, vertical channels therethrough, discs positioned inthek outlets of said channels pro-vided with langed heads adapted to close said outlets, horizontally extending grooves in the upper sunliace-oi'f said grate adapted for communication* with said channels `and vertical grooves in said discs adapted to establish communication between said channels and said horizontal grooves.; saidydiscs being rotatable to open land close such communication substantially as described.

2. ln a grate of the class described, vertical channelstherethrough, discs positioned in the outlets otsaid channelsprovided with flanged heads, adapted to close said outlets, horizontally extending grooves in the upper surface vof said grate adapted `for communication` with said channels and, vertical grooves in said discs adapted to establish communication between said 1 channels and said horizontal grooves; said disc being partially rotatable to regulate the degree of such c omniunication, scribed.

In testimony whereof lafhx my signature.
