Specification of Letters Patent. Patented Aug, 17, 1915.

Application filedJuly 3, 1913.. Serial No. 777,216.

To all whom it may concern Be it known that I, HENRY A. CARPEN- TER, a citizen of the United States, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have inventedalso for coke ovens, and similar eXteriorly-' heated apparatus, it has been the practice to form the retorts as independent structures from the supporting walls, and ordinarily of different materials and shapes, in which constructions the cross or vertical settings or supports have been placed at considerable distances apart.

An object of my invention is to provide a bench of such retorts of a structure wherein the formation of the blocks composing the cross Walls will also form the retort chambers themselves, and said retorts thus become integral parts of the complete bench structure. By such a construction a bench of retorts is provided'wherein all its parts, being composed of like-materials, will be subject to like influences by theconditions under which the apparatus is operated, and the difficulties incident toi constructions heretofore in common use. as above departs, Figure 1 is a longitudinal vertical section through a portion of a bench offgas retorts embodying my said. invention; Fig. 2, a vertical section on the line II'-II in Fig. 1; Fig. 8, a vertical cross section on; the line detail showing a portion of tworetorts illustrating the shape of the blocks composing the cross walls and said retorts and the manner in which said blocks are assembled to form the structure. V

In said drawings, the portions marked 1 indicate the main bench structure, 2. the retort chambers, 3 the cross vertical walls comprising the interior of the benchstructure, 4i the spaces between. the walls3, 5 a vertical side, 6 an opening leading from the combustion chamber 'of the furnace and III-III in Fig. 1; and Fig. 4, a perspective communicating. with the vertical spaces between the cross walls of the bench structure, 7 an intermediate wall between different divisions of the retort structure, 8 the blocks. of various forms comprising the cross Walls and formed withprojecting flanges 9 on one side.' Said blocks are composed of appropriate refractory material and the general structure of the apparatus, aside from the bench of retorts, is or may be of any appropriate or approved character. As most clearly illustrated in Fig. 4:, each of said blocks is formed smooth on one side and with a flange projecting outwardly on cross-section such as the arched top and flat bottom illustrated, or any other preferred form. The flanges surrounding each block are so arranged as to join end to end, the flange, on one block joining the flanges on the blocks on each side thereof, forming a complete flange around each retort chamber 2. The flanges of one cross wall abut against the faces of the adjacent cross wall, thus forming retort chambers 2 extending from end to end of the structure, which may be thus made of any length desired. The flanges 9 project a sufiicient distance so that narrow free spaces 10 are provided between the adjacent cross walls for the circulation of the products of combustion coming 1 into the bench from the combustion chamber, which spaces are completely bridged over around each retort chamber by said flanges.

Referring particularly to Fig. .3, it will be noted that the blocks 11 and 12 overlap the key blocks of the arch, z. 6., the blocks respectively forming the top and bottom of the adjacent retorts. By. means of this construction, the whole structure is interlocked, and it is especially advantageous in resisting a considerable amount of pressure from the interior of the retorts that is liable to occur in discharging the coke. As will be seen, the benchof retorts is formed of what may betermed units arranged sucthe spaces between these transverse walls, these bridging flanges with the blocks forming the walls of the retort. As a result, these spaces provide relatively narrow channels each of which forms a channel for the "circulation of the products of combustion. Furthermore, it willbe seen that each unit is practically composed of spaced columns of superposed blocks, these columns being connected by arch 1 structures at spaced apart points of the setting, these 7 arch structures practically defining the upper and lower Walls of a retort, the result being that the weight of a retort is placed sub.- stantially on these columns of superposed blocks and thus tends to restrict the effect of the weights of the individual retorts to points other than the retorts which maybe located therebelow. As will be obvious, the blocks provide vertically spaced retort openings as well as a structure in which a block forms an element both the setting and v the retort wall.

' This construction of' 'retorts not only forms a structure which is for all practical purposes an integral mass of refractory material of uniform character and susceptible' to-uniform influences under the conditions surrounding the operation of the apparatus. Such a construction not 'only is of decided advantage for the reasons above in di'catedQbut' for the further reason that when so arranged the mass of refractory i prior art.

material is capable of the highest efiiciency in transferringheat from the products of c'ombustiton to the coal in theretorts, but" this feature is the subject matter of a companion application filed herewith and will 7 not be further elaborated herein.

VVi th the construction shown and above.

described, any holes that may be formed in the retorts can be readily patched while the retorts are in operation and without the necessity of putting the retorts out of commission for the purpose of making repairs,
