JAMES ALFRED J ONES, 0F CHICAGO, ILLINOIS.
APPARATUS FOR QDBYING MOLDS.
To all whom t may concern.'
Be it known that I, JAMES A. JONES, of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Apparatus for Drying Molds, of which the 'following is a specication.
My invention relates to the manufacture of ingots and particularly to the drying of the molds in which ingots are cast.
It has been customary in many cases in the past to discontinue operations over Sunday or when repairs in furnaces are to be made and when operations are resumed the ingot molds which had been previously made .or which are made at that time are cold and frequently wet. In Vcertain instances attempts have been made to overcome this defeet by drying the molds by burning wood therein but this is an unsatisfactory andl expensive operation. It will be understood that the pouring of molten steel into a cold or wet mold in the manufacture of ingots is objectional, first, for the reason that it involves an element of danger to the workmen and second, for the reason that the quality of the steel is inferior. Tests have shown that there is a marked difference in the quality ofrails produced from ingots cast in cold and hot ingot molds, this being shown in the rejections of the rails, the difference amounting sometimes `to as much as 15 per cent. rIherefore1 it will be seen that the particular object of my invention is to provide means for quickly and economically heating the interior of the prepared molds. I have therefore devised an apparatus which is adapted to accomplish this result without undue loss of time.
In the preferred embodiment of my invention, I provide gangs of heating devices so arranged that a plurality of molds may be heated simultaneously. It will be under stood that in the common practice the ingot molds are formed on small cars, two to each car and that these cars are handled in trains by an engine. I have therefore provided apparatus of a capacity whereby an entire train of molds may be heated simultaneously.
My invention will be more readily understood by reference to lthe accompanying drawings wherein- Figure l is a side elevation of a device embodying my invention; Fig. 2 is a plan view of two sets of a gang of heating ap- Specication of Letters Patent.

of the mixer or nozzle of my heating vdevice and Fig. 4 is a lfragmentary view, partly in section, showing the manner of securing the mixer of Fig. 3 within the burner.
Referring more particularly to the drawings it will be seen that I'mount my improved heating device on vertical standards or columns 10 having supporting arms 11 extending at right angles thereto and havlng suitable braces 12 and 13. Sheaves 14 are mounted in the cross arm 11 on which is carried a cable 15 having a counterweight 16.011 one end thereof and the other end being adapted to support the burner or drying member 17. The cable 15 supportmg the burner is adapted for manual operation, the operator standing on the platform 18 provided therefor.
A series of molds 19 are placed upon cars 2O for transportation from place to place by means of the engine 21 shown in Fig. 1 or by any other suitable means.
Having described the general arrangement of my apparatus I shall now proceed to a description of the burner and the speciiic means for securing the best results with the greatest economy and operation.
The burner tube 22 shown in Fig. l as Cte pending within the mold cavity and in dotted'lines as raised above the pla-ne of the engine 21, is connected to a portion 23 eX- tending at right angles thereto and to which is connected a combustion chamber 24 have mg a series of perforations 25 therethrough. This chamber has on one end a hollow annular boss 26 within which is adapted to be seated nozzle 27 as best shown in Fig. 4. The reverse end of the combustion chamber is provided with an annular flange 28 having a series of perforations 29 therethrough the purpose of which is to provide additional air entrance spaces. Bolts 30 or other suitable means are employed for securing the combustion chamber to the portion 23 of the downwardly extending drying member. A. set screw 31 seated in the hollow boss 26 is adapted to secure and provide adjustment of the nozzle 27. The nozzle 27 is preferably circular in cross section and is provided with a series of longitudinal open- -ings or ducts 32, 83 and 34, the space 32 -oil and air. 'Ihe portion 34 is connected 4accomplished at a point very close to the Y with the openings 32 andby suitable pas-' y sage ways 35 and 36.' Y Tubes 37 and SShav# *vention as adapted for use with liquid fuel Ysuch as oil, it is evident that a combustible ing flexible hose connections communicate with the passages 32 and 33 respectively,A these flexible connections communicating .with a suitable source of oil' and air supply.
In order to drill the diagonal passage ways Q 35 and 36 I provide openings in line therewith, whichv openings are later closed 'by screws 39 and 40.`
Itl will be seen Vthat by myV improved nozzle' theactual mixing of the oil and air is point of exit and at a point which isvery yhot inview cf the fact that the nez-:cle extends for someV distance into the combustion chamber( VThis Vaccmnplishes more nearly 'if dperfect combustionthan if theair is' allo-Wed to mix with the oil and cool the same thus prevent-ing volatilization. It will be' seen that `the point of entrance of the combined air and oil into the combustionchamber may Vbe regulated by. means of the set screw w31.V
After 4,the combustion of the oil and air. Wit-hin the Vcombustion chamber 24, the llames are forced downwardlyV through-the.
`tube linto ythe mold vandY 4preferably at the Vlower end thereof. The heat,` of course,
tlien ascends and dries the entire interior of the mold cavity. .Thisdrying action is continued for a short period ofvtiine when the operator raises the `burners from the onthe same cable and counterweight for they Y `reason-that the Icars are usually adapted to,
contain two molds and as the molds are always centered on the car inV proper relation,
ing the drying, tubes pairs.
.the operation be simplified byrmount- Vliile I have shown and described my in-VVV gas may be used instead.'V Itis also obvious that modifications in the particular 4structure herein shown may readilybe made without departing from the spirit of my invention.
I` claim :V Y
1. An apparatus for drying ingot molds comprising in combination a traclgfa horizontal series offluid fuel burners suspended vertically over the' tracli in longitudinal alinement therewith and divided intopairs,
the members of each pair being spacedac- ,cording to the interval between aV pair of ingot molds standing. on a casting car, a flexible conduit leadinor from eachpburner to y.a source of fluid fuel, and means for raising and lowering,` each pair of burnersto introduce -them into and remove themV from ingot molds, substantially as described.
2. An apparatus 'for Vdrying` ingot molds comprising in combinationY a car track, a
pair ofiiuid fuel burnersfsuspended vertically over the track and alined longitudinally4 thereof andrspaced according to the interval vbetween a pair ofY ingot molds standing on a castingcar, a flexible conduit leading from each of the burners to a source of fluid fuel, and means `for raising and .low` ering ther` burners to introduce them into and remove them from ingot -molds, sub-v stantially as described. v Y y Y.LuynesALiiniD Jones.
