Application led April 20,

To all Aw/iom. t may concern.'

lie it known that l, PAUL A. Mnmmr, citizen ot' the United States, and resident ot' New Castle. in the county of Lawrence and State m Pennsylvania, have invented certain new and useful improvements in Kiln-Cars with Adjustable york-Supports, of which the following is a specitcation.

The general object of my present invention is to provide nnproved means for transporting goods through continuous tunnel kilns. More specifically the object of my invention is to provide xgoods transporting means for the purpose specified with simple and effect ive means for moving the goods on the goods transporting means as the latter ymoves through the kiln.` so as to equaliae the heat absorption b v different portions of the goods.

The invention was primarily devised for use in vulcanizingr tires but can adv-.inta geously be used in the treatment of many kinds oi goods.

The various Jfeatures of novelty which characterize nl v invention are pointed out with paricularity in the claims annexed to and forming a` part ot'. this specification. For a better understanding of the invention. however, and the advantages possessed by it reference should be had to the accompanyY ing drawings and descriptive matter in which I have illustrated and described preferred forms of apparatus embodying my invention.

Of the drawings:

Figure 1 is an elevation of a portion of a tunnel kiln with one forni of my improved goods transporting;r device therein.

Fig. 2 is a transverse section on 2--2 of Fig. 1.

Fig. 3 is a plan view of a modiied form of goods transporting device; and

Fig. fl is a section on the line f--fl of Fig. 3.

ln Figs. 1 and 2 ol the drawings, I have illustrated the use oi' my invention in connection with continuous vulcanizing apparatus comprising a tunnel kiln llwith track rails S `for the ears' A which carry the articles to be vulcanized through the kiln, and havin; combustion chambers T For heating' thr kiln located at the sides oi the pathway for the goods The kiln illustrated is of tile weil known Dressler type as shown. iur ea: cple.

` tire molds supporting it may be Patented Mar. l5, 1921i 1920. sum1 No. 375mm by the patents of Conrad Dressler 1U23l325 and 11704-28, but it to be understood that the invention is not limited to use in any particular type of tunnel kiln.

The goods carrying car l shown in Figs. l and comprises` a body portion A, Wheels B, and axles ille latter being mounted in bearings carried by thorar body. The car body A is provided at its opposite sides with uprising standards or brackets: Az in the upper ends of which are journaled a` shaft D. The latter carries spiders on which are detaclial'ily mounted the articles to transported tl'irongh the kiln. As shown these articles consist of the heavy metallic molds lj in which vehicle tires ai vulcanized. Provisions are made for rotating the shaft D, and thereby the tire molds and in chased` tires, as the car A movesalong the track rails Si. The provisions shown for this puriiiose. conilnise .1 pair of roller supports l joui-nailed, one on each ot' the or-.ickrts A?. and 'forming swliports for rollers D secured to the ends ol' the shaft l). The latter has its und portions received between bil'ureations Ap in which the upper end ofeaeli bracket A terminates. Secured to the shaft 'for earl) roll l? is a sprocket gearG. Each rear il is eoniiected by a sprocket chain ll to a corresponding sprocket gear C1 carried by one of the rar axles (l.

vWith the described construction as the ear A moves through the kiln. the supporting wheels F tor the shaft D. and thereby the latter. are correspond'ugly rotated. The rotation ol' ille shaft D revolves the rire moldsl P carried by the shaft. This tends to equalize llie heat :fibsorption by the nods l when, as only sometimes happen, the tcmperature in the upper portion of the kiln chamber is higher 1than the temperature in the lower portion l. The shaft D with the lifted bodily off the brackets when the removal of the molds is desired.

it will be understood of course that many different arrangements magT be made for automatically rotating, or otherwise moving goods carried on a kiln car, relatively to the latter as the rar is moved through the kiln. For iin-larice. il nia); be desirable to roi-ate the `rood ab' nl. a vertical axis instead of a horizon ir cases where the character of the ruin i infix, that zlilelenoes in temv -axles C so that as th articles to be 4 Eerature may exist between the sides of the iln chamber and the center of the latter.

ne form of apparatus for accomplishing this is shown in Figs. 3 and 4. The kiln qirs shown in Figs. 3 and 4 comprise a car y AA and a goods carrying revolve about a vertical s shown the goods cari' ing member I rests upon balls or rollers JY held in an annular runway A formed on the car bod AA The member I has a dependin shaftI carrying pulley wheels gIt. A cable belt HA connects the pulley wheels I3 with pulley wheels U10 secured to the car c ear is moved along its supportinv track rails the goods su porting member is rotated. As shown t ody is formed with a refractory superstructure A", and the goods carrying member I comprises a refractory upper portion Il of cylindrical form received in a cylindrical opening formed in the refractory car portion A1. he goods may be mounted directl on the upper end of the revolvin tion ,-but as shown, a stand member A is seated -on the portion Il.y and is provided with spiders EA on which tire molds simil lai' to those shown in Figs. 1 and 2 or other treated in the kiln may be mounted.

With the construction shown in Figs. 3 and 4 the roller bearing for the goods supporting member and the gearing connecting the latter to the car axle are protected against lthe .high temperature in the upper portion of the kiln chamber by the re rachory ciuportions A10 and I1 so that this form of my invention is adapted for use with relatively high kiln temperatures, such a tunnel kiln com as are employed for example in metal anhealing su bstantially higher than those comly employed in vulcaniziiig.

and demy invention now claim as new, and desire to secure by Letters Patent, is:

1. The combination with a tunnel kiln of a cai' for moving goods through the kiln and goods supporting means mounted on said car and adapted to move the goods relative to] the rar as the latter is moved through the 2. A car for transporting goods through rising in combination a car body, a rotatab e goods su porting memand means he car moves. for movin tunnel kiln comprising in combination a car body, supporting wheels therefor, and a' revoluble goods supporting member j naled on the car body and geared to the car wheels to rotate with the latter.
