ooNTmuous DECORATlNG-"KH.N.

"Be it known that I, JoHN GAMBLE, a citizen of. the United States,'residing at East decorated potteryware.

Liverpool, in the county of Coiumbiana and State ofOhio, have invented certain new and useful Improvements in Continuous Decorating Kilns, of which the following is a specification.

My' invention pertains to improvements in what may be termed kilns for treating its object is to provide for the requisite or uniform distribution of the heat supplied from. the furnace through the kiln for the. eiiectii-"e treatment .of the pottery-ware during the ,firing or burmng-m operation or setting the decoinbontihuation of the same.

rations thereon; secondly, to neutralize or counteract the draft action when the kilndoor maybe standing open, so as to prevent the. draft passing through the heating or firlng' section or portion of the kiln, which Wouldresult greatly disastrous to the burning-in operation and to the pottery-ware, and in order to shut off which draft an inner closure or closures or like means has been heretofore employed, and to provide for accomplishi'ng' -the aforesaid objects simple, expeditiousiand effective manner. 4

. Said inventiontherefore consists of certain features substantially as hereinafter fully dis closed, and

particularly pointed out by the claims. p ifln the accompanying drawings, illustrating the preferred embodimentof' my invention, Figures 1,1 are vertical longitudinal sections read in continuation one of the other thereof. Figs. 2, 2* are horizontal sections Fig. 3 is a transverse vertical section produced through the furnace and kiln O] 1. the line a: x of Fig. 2, Fig.-d isra broken horizontal section of the heating-section of the kiln, and Fig. 5 is a vertical section of Fig. 4,

In the disclosure of my invention. I suitably erect or construct the kiln. 1 and the furnace2, generally outlined or shown, of masonry, preferably of tiles and bricks, the latter being arranged laterally of the former and has What may be styled a central heating or firing section or chamber 3, and beyond the latter it is extended in both directions,

as at 4 4, in tunnel form, forming a covered,

approach and a ccrrespondingexit therefrom. Said heating or firing chamber or see- Specification of Letters Patent.

produced upon the line/ y Said kiln Patented March 12, 1907 tion 3 is provided or equipped with practically two series of heat conducting or distributing passages or lines 5 5 a series being arranged each side of a line continuously passing transversely through said sectiola or chamber and through the longitudinal center of the furnace 2, the latter being considerably nearer the feeding or receiving end of said section or chamber. Thus the greater heating or firing action is effected nearer the point the pottery-ware is initially introduced or received into the heating section or chamber, and said heating or firing action is gradually abated as saidpottery-ware isconducted or taken throughsaid chamber, and yet it is exposed sufiicie'ntly long to the heat there in to provide for the effective burning-in or setting operation. Said two series of heatconducting passages consist each of a continuous passage or flue having its receiving end 6 connecting uponeach sideof the line aforesaid with the furnace by a short flue 7 and passing upward, as at.8,th rough the front "the heat to said chamber for the effective treatment of the pottery-ware passed therethrough. An upright flue member 12 and 13, respectively, at diagonally opposite corners of the extreme ends of the two series of fines is, however, What may be styled dead,.

not being in communication with either of said flue series, and therefore not serving any practical purpose in that connection.

Certain of the vertical flue members of each continuous-flue formation are provided'with dampers 14 of suitableor' well-known form for controllingthe division and distribution of the heat or heat-currents as may be found necessary in conducting the burning in or firing operation, as will be readilyappreciated.

The tunnel-chamber is formed in practical I continuation of the heating or firing section 3 with extension-chambers 14 15, respec tively, that connecting with the delivery end thereof being the longerin proportlon to the greater length of said 'end of the heating sec' chambers are deflected or inclined laterally and in a direction away from the aforesaid walls, said alining walls having right-angled inward-extended end walls 16 17, -respec-' tively, each terminating a suitable distance the draft which would be induced when the from the deflected walls and intercepting a straight or right line touching any point within the cross-section of said heating section or chamber.

From the foregoing it will be noted that doors of the tunnel or kiln may be standing open would be prevented from setting up a current of-cold air through the operating or heating section, with disastrous effects upon the pottery-ware, but that a reactionary current would result by the backing up of the combined heat and air currents against the walls 16 17, thus bafliing or intercepting the passage of such cold-air currents as aforesaid.

Any suitable track or railway 18 may be laid extending through the kiln or tunnel and adapted by being suitably inclined, as indicated, for aiding the moving by gravity of the cars or trucks laden with the pottery- .ware for treatment through the tunnel or kiln, said track or railway being continued outside laterally, of the latter and returning from the delivery end of the-kiln to and merging with the entrance end portion of the, trackway.

Any suitably-equipped endless-belt mechanism 19, as shown, may be employed for transferring the pottery-ware-laden trucks or cars from the tunnel track or railway to the I outside or returning section of said track or railway, the latter also being so inclined as to aid the movement by gravity of said cars toward the entrance end of the tunnel or kiln for a new supply of pottery-ware needing treatment, as well understood.

The great importance and advantages of my aforesaid described improvements in this line of kilns will doubtless be appreciated from what has already been stated, and it is therefore thought that further or extended remarks inthatidirection would be unnecessary.

1. A kiln of the character described, provided with a heating or firing tunnel-section having two series of heat-conducting fines or passages communicating with a source of heatand extendin tortuously in opposite directions through t e walls of said tunnel-section.

2. A kiln of the character described, provided with a heating or firing tunnehsection having two series of heat-conducting fines or chambers, tortuously traversing the walls thereof in opposite directions and communicating with a source of heat, said source of heat being arranged n'earer theentrance end of said heating chamber or tunnel-section and the series of heat-conducting flues toward the delivery end having a greater rangev than the series of heat-conducting flues toward the entrance end.

3.- A kiln of the character described, having a heating or firing section and an extension-chamber with ,a right-angled end wall opposed to the plane of the entrance to the chamber of said heating or firing section, and a tunnel extension beyond said wall communicating with said extension-chamber said extension-chamber having an inclined lateral wall deflected oppositely to said end wall substantially out of the plane of said chamber-entrance.

4. A kiln of the character described, hav- 'ing a heating or firing section and'end extension-chambers each having a right-angled end wall opposed to the plane of' the entrance to said firing section and having an inclined lateral wallformlng wlth said rightangled. wall the entrance to said extensionchamber at a point substantially out of alinement with the aforesaid entrance.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
