To ell whom it may concern:

Be it known that LDANIELR. Russnnma citizen of the United States, residing at St. Louis, in the State of Missouri, have invent- 6 ed a certain new and useful Retort-Bench, of which the followin'g'is such a full, clear, and erect description as will enable any one skilled in the art to which it appertains to 5 H make and use the same, reference being bad 1 to the amompenying drawings, forming part of this SPEClfiQEttIOH,

My invention relates to retort benches, and more particularly to that class of retort benches which are provided with vertical fllhe object of my invention is to provide improved and simplified means by which the heating of the various parts of the retorts can be independently regulated so that 29 the highest temperature may be bad at the center or at either end of the retort.

e'lnflxthe ascompsnying drawings, which n cone of retort bench made in ,c eccordsnee with vmy invention Figure 1 is 21 a vertical centrsl section, Fig. 2 is a vertical eection on the line 2-2 of Fig. 3, Fig. 3

' is a horizontal section on the line 3-3 of 1 and Figs. fl and 5 are vertical cross- "sections on the lines H and 55 respec "Li -e marks of reference refer to similar 1 parts in the several views of the drawings. The retort bench consists of a front por- Igtion and a rear portion 11, therear por- Sdftion beingsupported by frame-work '12.

Formed in the lower part of'the front por ,tion 10 is e furnace 13 for generating furmace gas. This furnace 113 is provided with. .the usual flue 14*, gratelfi and ash pan 16. 'Gommunicating with the furnace 13. is a -fiue 17 for conducting the furnace gases to the. various heating or combustion chambers 18. The flue l? communicates with the heat- .ing'or combustion chambers 18 by means of the passages 19, as best shown in Figs. 1 and 3. The heating chambers 18 are SIX in number and are formed in pairs by means of passages 20," as bestshown in Fig. 2.' Each pair of chambers thus constitutes-a set which are connected together but which are entirely independent of the other "sets. -Passing 1 .through the various chambers 18 are ,ver-

tical retorts 21 which, in the form of furnace shown in the drawings, are four in number. In order to insure the circulation of the heated gases around the retorts 21 each of the chambers 18 is provided with a pair of short bafiie walls 22 connecting the front' pair of retorts" with the front portion 11 of the furnace, a-pair of bafiie walls 23 connecting the front and rear retorts and pro vided with passages 24:,and also with a air of inwardly projecting battle walls 25. idfhile each set of combustion. chambers is thus provided with two gas inlets, but a single outlet is provided for the gases from the two chambers constituting a set. This outlet 26 communicates with a set of recuperator fines 27, as best shown in Fi 2. The sets of recuperatorfiuesare, there ore, three in number, one for each set of heating chambers. The gases, after passing through the recuperator flues 27 enter the chimney 28 through a passage 29. Each of. the passages 29 1s provided with a valve or damper 30 by. means of which the passage of the gases to the chimney is regulated, thus indirectly regulating the passage of gases from the flue 17 to the two correspondin chambers. The rccuperator lines 2 may be provided with the usual stoppers 31 for givingaccess thereto.

In order to supply heated secondary air eating at one end through a passage with one .of the COHlbHStlOll chambers and at the other through a passage 34 with the atmos-v phere. The passage 34 is controlled by.

means of a damper 35 so that the supply of secondary air may be regulated to correspond with the amount of gases entering the heatin chamber.

In the operation of my retort beiicli,- the rctorts are first charged; in the usual manner and the furnace 13 supplied with fuel. The heated gases from the furnace 13 pass up through the fiue 17 and into the various heating chambers 18 through the passages 19. The amount of gases entering each set of heating chambers, however, can be indeheating to the various combustion chambers, each of thelsets of recuperator fines 27 is provided 5 with a pair of sinuous passages communipendently regulated by means of the valves or; chambers 30 as the gases will not enter the heating or combustion chambers unless a corresponding amount of the products of combustion can escape through the openings 29 into the chimney 28. At the same time a supply ofsecondary air to each of the combustion chambers can be independently regulated by means of the dampers 35. In this way perfect control is obtained of the heating of the retorts throughout their entire length and at the same time the construction is simple and not liable to get out of order.

Having thus described my invention, what I claim as new and desire to, secure by Letters Patent of the United States is:

1. The combination with a retort bench, ot' a vertical retort in said bench, said bench being provided with a plurality of heating chambers surroimding said retort, said chambers being arranged in sets separated from each other buthaving the chambers of each set connected, air and gas inlets for each chamber and a common outlet for the chambers of each set.
