EDWIN E. QUDVKER, OF VALDOSTA, GEORGIA.
Application filed February 13, 1920. Serial No.
To all whom it may concern: Be it known that I, EDWIN E. QUINKER, a citizen of the United States, residing at Valdosta, in the county of Lowndes and State of Georgia, have invented certain new and useful Improvements in Protectors for the Heating-Pipesof Retorts, of which the following is a specification, reference belng had to the accompanying drawmgs. I
This invention relates to retorts used for the dry distillation of wood, and particu-' larly to means for protecting the heating pipe at the point where the heating pipe leads from the furnace into the heater;
The general object of the invention 18 to provide means whereby heat may be applied to or conducted 1nto a retortior the distillation of wood without burning the retort and without burning off the end of the heating pipe where it extends on the outside of the retort.
A further object is to provide means which will prevent the intense heat from the furnace from following the heating pipe to the retort and burning out and weakening the head of the retort.
And a further object is to provlde a stuffpacking through which the protective water jacket or shield extends into the retort.
A further object is to provide means whereby the water jacket may be connected to the condensing tank or storage tank of the retort so as to secure a circulation of water through the water jacket.
Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawings, wherein Figure l is a sectional view of a retort showing diagrammatically the condenser, furnace and the connections leading thereto;
Fig. 2 is a diametrical section through the water jacket and stufling box;
Fig. 3 is a section on the line 33 of Fi 2 nig. 4 is a fragmentary section through the retort showing another form of packing or stufling box and showing the manner'in which it is attached to the retort.
Referring to these drawings, 10 designates generally and more or less diagrammatically, a retort for the distillation of wood or for other purposes. This retort may be constructed in any usual or suitable manner, and when in use is closed at one Specification of Letters Patent.

end by means of the closure 11. discharge tion of the retort and discharges into a condenslng 0011 13 disposed in a condensing discharge pipes lead designated respectively 15 and 16, the pipe '15 being for the discharge of dry vapor, while the'pipe 16 forms an oil outlet and discharges into an oilreducing tank 17 The heat for the retort is secured from a furnace 18 of any usual or suitable construction, and the retort is heated by one or more heating pipes 19 leading from the furnaceinto one end of the retort and ex tending through the retort in a more or less circuitous manner, and then out of the retort to a stack (not shown) by means of the stack connection 20. The heating pipe may be formed in any suitable number of sections, and I have shown that portion of the pipe leading from the furnace into the end of the retort as being formed in two sections connected by a coupling or joint 21. From the bottom of the tank leads a discharge pipe 22, by which heavy tar is discharged from the retort.
So far, I have described and illustrated an ordinary and common form of retort for the dry distillation of wood and other like materials, and it is to be understood that none of the parts heretofore described are my invention but may be of any usual or suitable construction. 1
It will be noted that the furnace 18 is spaced some little distance from the head 23 of the retort, and that the heating pipe 19 extends from one end of the furnace through this head 23. The moisture evaporated from the wood in the course of its distillation sufficiently protects that portion of the heating pipe which is disposed within the retort and prevents it from being burned out, but ordinarily the heating pipe on the outside of the retort has no protection and this exposed portion of the heating pipe is very liable to burn off or burn out. Furthermore, the heatfrom the furnace passing into the heating pipe tends to burn and weaken the head 23 of the retort.
To avoid this I have provided a Water jacket 24 which surrounds the exposed portion of the'pipe 19 and extends from the end wall of the furnace to and through the head 23. This water jacket 24 is spaced I and leading to the upper portion of the box or gland might be used.
traction of the heating su'liiciently from the heating pipe 19 that it may contain a suflicient quantity of water to prevent the heating pipe from being burned out and prevent the conduction of heat to the head 28. I have shown this water jacket as attached to a short-section of pipe 19 forming a continuation of the pipe 19, and which is connected to the pipe 19 by means of the pipe coupling 21. This makes it easy to form the water jacket and.
put it in place. 'Ihave illustrated this water jacket as extending through a stufiing box or packing gland disposed in the head 23, this stufiing box being designated generally 25, and being filled with packing 26.- I do not wish to be lim'ted to the particular form of the stufiing box or gland illustrated, as it is'evident that other forms of stuihng This stuffing box is attached to the end wall 23 if the retort and permits the expansion and conpipe and water jacket, while at the same time preventing the outlet of any vapors from the retort,
and also aids in insulating the wall-oi 'the retort from the The jacket 24 is, preferably connected by meansfofinlet and outlet pipes to any suitable source of water whereby the water in the jacket may be kept cool.
Thus I have illustrated a water outlet pipe 27 extending from the water jacket tank 14, and a water intake pipe 28 as extending from the bottom or lower portion of the condensing tank into the waterjacket.
Thus I secure a circulation of the water from the water jacket into the. condensing tankand thus secure a constant'circulation into one end wall or of relatively cold water within the Water.
jacket and around the pipe section 19 While I have illustratedfmore or less diagrammatically a particular form of retort to which my inventionis applied and have illustratedthe pipe section 19 as extending head of the retort, it is 'to be understood that it might extendiinto the side of the retort or into any other porthe stuffing or thesidcs of the retort without any flanges,
bolts, rivets'or. the use of a stufling box and packing, as illustrated in my Fig. 2; Thus the heating pipemay be welded to "the re-;

retort, or the de- Welded to the'head of the retort and the other end of thejacket welded to the heating pipe where it' goes into the furnace. There are objections to this method of fastening the heater pipe to the head by welding. One of the main objections is that the expansion andcontraction soon cracks the welding and 'causesthe water from the water jacket to leak into the retort. Further, a welding outfit must be used to do the welding, and as most 'retorts are in the woods, and as one of the objects of the invention is to provide a heating pipe pro-' v tector chamber applied toa retort in actual practice, expensive to take a welding outfit into the woods and weld up any breaks which might occur between the water jacket and the retort.
'One of the objects, as above stated, is to provide a standard water jacket that can it is obvious that it would be very be made in the shop and shippedanywhere where there is a still and then the owners of the still canv apply the waterlj'acketed pipe sectionfthrough the stuiling box and connect it by means of the flange coupling, as illustrated in my Fig. 11. -I do not'wish to be limited, however, to the particular manner of forming the stuiiingboxl illustrated in Figs. 1 and '2, and'in Fig. 4 I show a construction wherein'the stu'liing box is formed bybolting collars 29' on each side of the head of the still," these collars being interiorly screw-threaded to receive, pipe nipples 30 which form. the casing o f the stu'liing box and within which packingis disposed in the manner the packing being compressed and'lfo'rce'd against the wall of the nipple by any suit able means as for instance, by the longitudinally extending bolts and nuts previously heretofore stated,
described in connection withFig. 2.; The" I use of this stufling box permits the device to be applied withoutcareful fittingof the parts and without the expense of welding the parts to the still.
