TUNNEL-KILN CAR .AN'D METHOD 0F LOADING WARE'. THEREQN. i

Application ed June' 22, 1927. Serial? Nol. 2065,539

The present invention relates to a ware supporting deck construction tor kilnv ears arranged to move through a tunnel kiln in which the ware' is subjected; to firing,y` operations, and` the object ot my invention is to provide improved: means for supporting feranrif' ware during the passage through the kiln and' which 'maybe mounted upon and torm a permanent structure upon' the trucks or cars used in: the tunnel kiln. Another object is toY provide a novel method oit loading ware. on the ware supporti-ng structure;

The variousV features of novelty rwhich characterize my invention are pointedl out with particularity in the claims annexed to and' formingl a part of this speciftica-tion. For a better understanding' oit' theV invention', lrowcver', and` tlre advantages possessed by it reference should be had to the accompanying drawings andi descriptiveV matter in which l have illustrated andl described a preferred embodiment' of the invention.

Ot the drawings y Fig; l is a slide elevationot" the body portion of: a ware supportingcar with .my improved si-Ipporting structure mounted thereon Fig. 2^ is a plan view ot the structure shown in Fig.. l with portions of tlietop deck. broken. away ;A and Fig; 3 is a perspective View ott'lieremovable post ot my invention.

ln the construction illustrated iny Figs; 1 and 2', represents the refractory body portion et5 a truck or car' such` as is commonly employed in continuous tunnel kilns'.V At the top of the body portion oft' the car are mounted. transverse beams B which form supports for the load upon the car and are spaced away from one another to provide channels C' extending transversely' to the length of thecar; Supported o-n adjacent transverse beams are a plurality ot Hat reliact'ory` slabs D' forming the lower deck ot the Ware supporting superstructure. fn the construction shown siXf of these( slabs' are used to form the deck. Supported on each slab D and1 suitably spaced from eacli other area; plurality of waresupporting posts comprising corner posts E and. E intermediate side post and a. central' removable post G.

Each of the posts E and F consists ot a vertical reliractory bod-.y ot general ytrian- `guiar sliape comprisinggsolidl topi and bottom portions E2 anti E3; respectively,v connected bytwo integral' side portions E? so arranged that a vertically extending` recess is torn-lod by the backs of the side portions in the rei-naming side of the post. The solid side portionsli are arranged to` face inwardly from Vthe sides of the car andI are provided with a veifficallyV spaced series of triangular shaped' slots H extending through and inclined from the inner to the recessed outer side ot the post. The slots Hi are adapted: to receive triangular shaped pinsI K projecting inwardly :troni the inn-er side off the post and on which plates or other flat ware are supported for glost orV other firing opi-nations. '.lhe slots H are tapered at their outer ends to hold the pins in positions with a predetermined: portion projecting` from the tace ot the post as showny in Fig.. The corner posts areot slightly different construction trom` the posts E. and. F in that the rear side only is providedV with pin slots and the other sides are' cut away at one end as shown in Fig. 2.

The central post Gr is of slightly kless height than t-lie other posts and has its top portion G provided with a central recess G2. Otherwise theV post G is of the same construction as the posts E and' l?.

A plurality ol dat slabsr M.' ot the same shape and size as the slabsfDi are supported on thel corner and side posts E, E" and.' E to provide an upper deck for the ca-r.. In the center ot each slab M is arranged ani opening lv through which a movable pin M2 projects and i'its into the recess G2 of the central post The inner side of the slabs M are arranged with `cut away portionsk M3 sliown in Fig. 2 to provide passages for the circulation ot the kiln atmosphere; AThe slabs D are constructed with! similar passages.

For the contemplated use in my invention, the corner andl side, posts are tir-st positioned on the lower deck slabs D of the can with they pins K inserted in positionl in the posts. The top slabs M are then placed in position on the posts to form the remaining part ot the permanent superstructure. rlhe innermost bungs ot plates N and Oli or similar ware are inserted in'- position -on the pins mounted on the inner corner and intermediate side posts E and F respectively. The central post G is then mounted in position on the slab with its recess G2 in alignment with opening M inthe upper slab. The pin M2 is inserted in the opening and engages in the recess of the post to hold the post in position. The outer bungs of plates P and Q are then placed inposition on the pins mounted in the remaining posts. The remainingportions of the car are loaded in a similar manner with the rear bungs being placed in position first, the removable post G inserted and the outer bungs then placed in position. As shown in Fig. 2, some of the posts will assist in supporting adjacent slabs of the upper b ack and also have their rear vportions contacting with the rear sides of 'the corresponding posts supporting lother sections ot the upper slab structure. lith the construction described, the circulating passages formed in the slabs and between the supporting` posts of the deck structure permit the kiln chamber atmosphere to be circulated through and around the ware being heat treated. .lt is obvious that after the lpermanent part oli the superstructure has been once placed in position, that. only the posts G will `be moved during subsequent loading and unloading operations.

f `My invention is especially useful in the tiring of table ware, as the cars can be loaded without the necessity of transporting heavy ware containing saggers such as are normally usedin such operations. This permits ot the use of relatively cheap female labor in loading the cars. The orinationoit the kiln car with a permanent superstructure eliminates thev use oi saggers which are often broken in the loading operations with resulting damage to the ware contained therein. It has been found in practical operation that more ware can be loaded ina given space on the ear with the present structure than was .possible with any of the former deckv constructions in use. n

While in accordance with the provisions of the statutes, have illustiw-.tedraiul described the best form of embodiment ot my `invention now vknown to me,`it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing Yfrom the spirit ot .my invention as set forth in the appended claims and that in some cases certain features ot my invention may be used to advantage without a corresponding use of other teatures.

Having now described my invention, what .I claim as new and desire to secure by Letters Patent, is:

l. ln a kiln car, a ware supporting superstructure comprising a permanent arrangement ot slabs and posts and a. removable post having ware supporting means cooperating with said permanent structure for directly supporting wareto be heat treated. 2. A ware supporting` superstructure 'tor a kiln car comprising a lower deck, a plurality of posts ymounted on said deck, an upper deck mounted on said posts to form a` permanent 'superstructure' Vand a removable post adapted to be placed in position between said decks and to cooperate with some of said ifirst mentioned posts in supportingV structure and cooperating withsome ot said post to support the outer biings of ware.

t. na kilnvcar, a supporting superstructure arranged to support a plurality of vbungs ot flat ware and comprising a permanent arrangement of posts having ware. supporting meansby which some oi the bungs are supported and a removable post having ware supporting means cooperating` with part of said permanent structure to support` others of said bungs o ware. V

5. A ware supporting superstructure 'ter a kiln cai* comprising a lower deck, a plurality of posts mounted on said deck, an upper deck mounted'onsaid posts to form arperinanent superstructure, a removable post adapted to be placed in position between said decks and cooperating with said first mentioned posts to support wai'e to be heat treated and means y in said upper deck for holding said removable clement in position. y

6. Aware supporting superstructure for a kiln car comprising a lower deck structure having circulating passages therein, a plurality of posts and slabs'supported by said lower deck, ware supportingl pins mounted in Y 7. In firing ware in tunnel kilns, the` m-ethod of loading ware lired on a kiln car comprising a ware supporting superstructure which consists in arranging the ware in bungs adjacent the longitudinal center line ofthe car, inserting a removable supporting-v element in position in said superstructure and arranging bungs along the outer portion of the car so that they are partially supported by the removable element.
