j The general object of my present invention is to provide improved means for sup porting the load-carrying super-structure of a kiln car such as is used in tunnel kilns, and analogous industries. More specifically, the object of my invention is to provide an 1mproved removable supporting element, or post, for supporting the upper deck or decks of a kiln car havingtwo or more decks on which. wareis carried through a tunnel kiln for appropriate heat treatment. My 1111- proved supporting post is made of fire clay or analogous material, and is characterlzed by its construction in separable parts so shaped that the eflective length of the post ma 7 be varied by a simple adjustment of one of 1ts parts relative to the other.

The various features of novelty which characterize my invention are pointed out with particularity inthe claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and the advantages possessed by it, reference should'be had to the accompanying drawings and. descriptive matter in which I have illustrated and described a preferred embodiment of the invention.

Of the drawings-:

Fig. '1 is an elevation partly in section showing my invention in use on a kiln car, Fig. 2 isan elevation of one form of post;

Fig. 3 is an. elevation partly in section of amodifiedtform withthe component parts separated; 6

Figs. 4, 5, and 6 arc v iews of other modified forms of cap pieces. 7

In the drawings is shown an open deck tunnel kilncar. A, having the usual wheels and supporting base and carrying three decks A, A and A, each consisting of a plurality of flat slabs of refractory material. The upper decks are supported by vertical post elements B andD of various forms and construction. Some of the supporting posts designated by the letter B may be of the usual hollow, cast fire clay type, while others may be ofthe adjustable form which is the subject of the present invention. i i

In Figs. 1 and 2 of the drawings is shown a simple form of adjustable post D consisting of a base or body portion and a top or cap portion E. The body portion of the post D is of cast or pressed fire clay or other suitable refractory material, and, as shown, is formed with an axial passage D extending from its lower end upward for the greater part of the length of the post. At its upper end the part D is formed with an integral cylindrical tenon-like extension D of reduced cross-section. The upper end surface of the annular portion of the base D surrounding the base of the projection D. is of screw or cam form being formed, as shown, to provide two similar inclined surface portions or sections D? and D each extending half way aroundthe tenon D .The topor cap section E of the post which may be made of the same. material as'the. body portion of. the post D,is formed with an axial passage or socket. E in its lower end in which the tenon portion D of the body portion of the post D fits and is rotatably received. The lowerend surface of the member E is screw or cam shaped, comprising sections E and E shaped similarly to, and contacting with the surfaces D and D Theefl'ective lengthnof a post formed as described ofa part ,D and a part E maybe varied by rotating one part relative to another. In Fig. 1, the adjustable post beneath the upper deck A is shown in its contracted form in which it doesnot engage the deck A and, hence, may be readily removed and replaced preparatory to, and at the respec tiveware unloading and loading operations.

The adjustable post D, shown as forming one of the supports for the car deck A has its cap portion E rotated relative to the body portion. To facilitate. therelative rotation ofthe post sections to expander increase the length of the post sothat the latter will take its propershare of the weight of the platform A, the two sections of the postare shown as formed with holesE and D in which bars or like implements. may be inserted. The top and bottom section of each. adjusts able post may be positively secured in their adjusted positionby wedging a piece. of clay F or other material in the recess formed between the end of the cam portions as shown in Fig. 1. Ordinarily, the use of such wedging material is unnecessary as the friction between the contacting surfaces is usually sufficient to prevent the parts slipping from their adjusted positions.

The form of postshown in Fig. 2 with'its spherical top does not provide a large sur face'in co1i'tact'-\vitl1 the slab or deck portion wh'iclrit engages and-supports. .Various ar= rangements are shown in Flgs. 3-6 by which the contact area is increased, and an even bearing surface provided when the slab is not exactly at right angle's'td the post; In these Figs. 3 to 6 posts are shown as provid'ed'at their upper ends each with a" separate auxiliary cap piece or bearingmeinber ha'vin'g spherical contact" with an adj afcent surface of' the top: section. In Fig; 3' the bearing member G'is" shown as'having a flat top portion G and a' depending tenon Gr received in a cylindrical socket E in" the upper end'of the cap section EA and of slightly larger" diameter than the tenon G The tenon G is" forn'i'ed'with a spherical resting inac'oncave surface of greater di-' ameter formed'ln' the top ofthecap sectlon" EB of'th'e post. In Fig. 5 the bearingmembe'rG'Bis provided'w'ith a concave recess G in its lower surface in which fits a convex projection'bn the upper end .of the cap section'EG. In Fi'g'.'6"the bearing" member GC is formed with a substantially spherical knob projeetion'Gr engaging in a similarly shaped recess' in the topsect'ionE'D. On the top surface of'ea chof the inembers'GB'and GC shown in Figs: 5' and6 are provided slightly spaced projections G for engaging the slab which" is supported by the member.

My improved posts with'their' self contained length adjusting provisions are simple and effective. They are appreciably easier to install and adjust than the nonadjustab'le' post-s heretofore einployed'which have been securedinplace by separate wedge parts which are sometimes shaken out of place. In'fOIHKGYClGSigHS separate wedges were used to raise the posts. .These'wedges had a tendency toslip out of position when suddenly jarred. In the present invention the we'dge is incorporated in the post itself;

hjilein' accordance with the provisions of" the statute's, I have" illustrated and" tie scribed the "best form of embodiment of my inventionnovv" known to me, it will be apparent" to thoseskilled in theart that changes may" lee made in the form OIE'iZhB apparatus disclosed without departing from the spirit of my invention as set forth in the appended claims and that in some cases certain features of my invention may be used to advantage without a corresponding use of w other features.

Having now described-my invention what I claim as new and desire" to secure" by Let tersPatent is 1; A self containedadjustable deck supportingpost for akiln car formed of relatively axially movable refractory parts to vary tl1e' 'effective length of said supporting post.

2;" A decksupporting element for kiln cars comprising a base portion and a cap portion Ofi'efractOiy' material rotatably connected and adapted by their" relative rotation to vary the effective length of" said supporting elei'nentf 3'." A decksupporting element'for kiln cars comprising a basepo'rtion'a'nd a cap portion offrefractorv material rotatably connected and adapted by their relative rotation to vary the effective length of" said supporting element, and means for lioldingsaid portions in" the adj uste'd" position.

45. A deck supporting element for kiln cars coi'nprising a base section and a cap section of refractory material in rotatable engagement with one another and having contacting surfacesinclined'to their axes of relative rotation iwlierebythe height of said supporting element may be varied when the sections are relativelyrotated.

5. A deck supporting element-for kiln cars comprising a base member of refractory material having a tenon-like projection at its upper end; cap-member of refractory material having a socket in'its lower end in whicli'said projection is rotatablyreceived, said members having cooperating inclined contact surfaces whereby the height of said supporting element may be varied byrotating said" cap member relative to said base member.

6. A deck supporting element for kiln cars comprising a base member of refractory material having a tenon-like projection at its upper end, acap member of refractory mater'ial having socket in its lower end in which said projection is rotatably received, said members having cooperating inclined contact surfaces whereby theheight'of said supportingelement maybe varied by rotating said cap member relative to said base member, the contacting portions of said members being shaped to'provide a recess in which cl'ay'may be inserted-to lock the parts against rotation inthe direction to shorten the length of t-hepost;

7. Ana-dju'stable' decksupport for a kiln car superstructure comprising agba'sesection member, a cap member rotatably connected to said base member, said members being formed of refractory material, and having Q bers, and a deck engaging bearing block rotatably mounted on said cap member and adjustable thereon to accommodate surface irregularities of the bearing block and deck portion engaged by the latter.
