TURPENTINE-DISTILLING- APPARATUS.

- To all whom'z't-mayccncern:

. following is a full, clear, and exact description of the invention, such as will enable i. others skilled in the art to which it appert-ains tom'ke and use the same.

This invention relates to turpentine stills, and has particular reference to condensing apparatuses therefor.

The object of this invention is to provide an apparatus for separating the turpentiiie which has been condensed from the vaporous contingent which normally exists in the still warm distillate, and condensing the vaporous contingent into rectified turpentine.

A further object of the invention is to provide a separator for removing the water from the pure turpentine, and then coo-ling the latter to atmospheric temperature to condense it to its normal specific gravity for barreling.

A further object of the invention is t0 make the process of condensing the vaporous contingent of the distillate a part of the water and turpentine separation process, so that the rectified turpentine which results from the condensation of the vaporous contingent will be automatically added into the `main body of the distillate to go through the separating process therewith.

It is a well known fact that the distillate which comes from the worm of the usual distilling apparatus possesses an appreciable degree of heat, and that approximately one- -tenth part of the spirits passes entirely through said worm in vaporous form and escapes into the atmosphere from the outlet of the worm. Furthermore, the distillate consists of a mixture of turpentine and water which must be separated. Furtherinore,thc

turpentine, in its heated state as it is received from theworin or condenser is so hot that it is impossible to barrel it before a thorough cooling, without making the turpentinermliable to Iayment for losses due to the shrinkage of t e turpentine within the barrels as the product Ycools by condensation,

and assumes its normal specific gravity. Generally speaking, then, it is the purpose of this invention to provide a condensing and separating apparatus which receives the normal distillate from a still and delivers all of it in the form of pure thoroughly cooled and condensed turpentine which may be barreled and shipped.

With the above objects in view, and such others relating to the details of construction, as may hereinafter appear, `our invention will now be fully set forth and described, reference being had to the accompanying drawings.

Fig. 8 is a detail of a supportin bracket.

Referring more particularly to t e drawings, 1 represents a tank which may have any exterior conformation, exce t that it must be comparatively high, an is subdivided on a line somewhat above the middle of its height by a transverse partition or Hoor 2. Upon the floor or partition 2 are mounted the standards 3 which are transversely connected by means of the cross bars 4, said cross bars 4 providing suppsorts for a plurality of coils or worms 5 he coils 5 are preferably three in number, and are contained one within the other in spaced relation, and are furthermore built up of such a number of turns as will meet the requirements of the articular apparatus which is installed. he upper ends of the coils 5 terminate in a common manifold or cou lingrfi from which water is fed through the wall of the cylinder above the partition 2. From the open end ofthe pipe 10, the distilled splrits fall upon an incline plate or baille 11, which is preferably formed of glass, the arrangement bei-ng such that the fall from the end of the pipe on to the bale is practically noiseless, so as not to disturb or destroy the usefulness of the ear trumpet 12 carried by the pipe 11 and which is employed in apparatuses employing secondary condensers whereby an expert operator may ascertain the contents and condition of the distilling spirits. Also, provision is thereby made for the periodical extraction of spirits from the end of the pipe 10 by the insertion of a cup into the chamber 9 through the inspection doorway or trap 13. Below the partition 2, the tank 1 is double walled, so that a comparatively heavy water s `ace or chamber 14 is provided, and furtermore, parallel transverse walls 15 subdivide the lower part of the tank into a pair of chambers 16 and 17 and also form a water space 18 which communicates upon opposite sides with the water chamber 14, so that 4the chambers 16 and 17 are entirely surrounded by water jackets. The water chambers or spaces 14 and 18 are connected with a water supply by way of the pipe 8, above described, which is coupled into the Wall 1 of the tank at a suitable point, a valve 19 in the pipe 8 providing a proper control' element. A circulation is permitted through the chambers 14 and 18 by means of a drawoi valve 20 located near the upper end of the chamber walls, and a reiease valve 21 at the top thereof provides an escape for air which might be otherwise confined in the chambers by the rise Vof the water therein. When it becomes necessar to completely drain the Water from the c ambers, the valved outlet 22 at the bottom of the structure is employed.

The chambers 16 and 17 communicate with one another by means of an over-flow port 23 which is passed through the walls 15 so as to traverse the chamber 18, the ort 23 being located a't a height above the ottom of the tank which is determined by the capacity of *the apparatus, as will hereinafter appear. The chamber 9 overows into the chamber 16 through an over-flow device 24 which empties into a trough or spout 25, the latter passin to a point just above the bottom of the c amber 16. The oversflow device 24 also provides a trap which confines a certain quantity of liquid Within the chamber 9 whose level acts a seal a 'nst Vthe passage of vapor from the chalnelr 9 throu h the over-How device 24. Thus, the overow device or trap 24 consists of a -flat and comparatively broad mouth 26 which lies flat against the partition 2, and empties at its rear end'into a funnel 27 which terminates the upper end of the trough or spout 25, Between the mouth 26 and the funnel 27 the broad flat structure of the device is bumped or upwardly curved `in an elevation 28 which rises above the mouth 26 a distance equal to the vertical dimension of said mouth, so that the passage of liquid through the trap is only possible when the level in the chamber 9 exceeds in depth the height of the mouth 26. In this manner, any vapors which issue from the inlet pipe 10 are prevented from being drawn through the over-flow outlet from the chamber 9 into the chamber 16. When it is necessary to completely drain the chamber 9, a plug 29 which is entered into the partition 2 .to cover a drainage port 30 whose upper end is flush with the upper surface of the partition 2, is removed, the plug being accessible through the door 13. The chamber 16 is drained through an out let port 31 which is branched into a take-off conduit 34 which is controlled by means of a globe valve The branch 34 is comnected to a source of water supply by any convenient means so that as a preliminary step to the operation of .the apparatus water may be introduced into the chamber 16 for such purposes as will hereinafter appear.

The chamber 17 has an outlet spout con duit 36 passing through the walls of the chamber 14 at a level slightly below the level of the over-flow port 23, the conduit 36 terminating, generally, in a filling spout from which barrels may be filled with the condensed turpcntine, a suitable valve 37 pro The viding for the control of the outlet. cham er 17 receives the finally condensed and cooled turpentine as a commerical product, this body of spirits being received through the port 23 from the chamber 16 in which the turpentine is separated from the water of condensation which has come through the chamber 9 with the distillate from the condenser, this separation resulting gravitally by reason of the different specific gravities of the water and spirits. A gage 38 which is disposed upon the outside ot' the chamber 16 is properly arranged to indicate the relative level of spirits and water within the chamber 16.

In its operation, the utility of the present condensing and separating apparatus rests principally in the recovery of the usual onetenth part oi' the turpentine spirits which has always passed off as a vaporous waste after the distillate has passed through the worm of the old distilling apparatus. Therefore, in installing the apparatus of this invention, the tank 1 is so disposed that the pipe or conduit 10 which is the usual spirit outlet from the distilling apparatus,

will deliver the product into the chamber 9 the' spirits falling uponthe baiie orncline 11 in a noiseless manner so: asnotto destroy the effectiveness ofv the ear trumpet 12. As stated, the distillatef consists of one-tenth vapor and therefore nine-tenths condensed splrits and water, still in a Warm state.` The condensed product passesvfroni the chamber 9 through the trap 24 intothe chamber 16, where, by the action'ff gravity-th water collects at the bottornof"l the chamber and the turpentine lies thereon in a superimposed body." Iii itis necessary for the tproper operation of the apparatus, a body o Water may be introduced into the bottom of the chamber 16 through the Water pipe 34 and the inlet 31, thus elevating the body of spirits which rest thereon to a level where it will overflow from the chamber 16 into the chamber 17 through the port 23. Vice versa, if the Water body becomes too great in the chamber 16, it may be drained by opening the valve 33 so that the Water may be drawn ofi' through the pipe 32. Within the chamber 16, the condensed s irits undergo a cooling rocess through t e action of the Water in t e chambers 14 and 18 which entirely surrounds the chamber 16.

The vapor which enters the chamber 9 and is separated from the condensed spirits rises in the space around the coils 5, the latter having been filled with still or circulating Water which is distributed from the manifold or couplin 6 into the several coils. The condensed products which result from the circulation of the turpentine vapors among the coils 5 falls into the chamber 9 and is added to that'body of distillate which overflows into the chamber 16.

As soon as the level of the turpentine in the chamber 16 reaches the point Where it will overow throu h the port 23, it passes as a commercial procgluct into the chamber 17, with the exception of the fact that it is still above its normal specific gravity because it still contains a certain degree of heat. As it cools in the chamber 17, however, the Water in the surroundin chambers 14 and 18 completely cool the distillate, so that b the' time it reaches that point where it wi l overlio'w through the outlet 36, it is condensed to its normal s ecic gravit and is ready to be barreled immediately or shipment without dan er of future adjustment for shrinkage of t e contents of the barre] by reason of the fact that the tur entine was barreled before it had thoroug ly cooled. When the distilling process is over, and there still remains Withm the chamber 16 a body of turpentinewhich cannot pass through the port 23 and by reason of the low level of the Water body in said chamber 16, the latter may be increased by an additional water supply from the pipe 34, until the turpentine body has been raised to completely drain into the chamber "17. After. this, the turpentinethen remainingin' chamber 17 may. be torcedout ofthis chamber 17, through outlet conduit 36, by continuin iniiow of, water through 34 until sufficient has followed `the turpentinefinto chamber 17 to raise all the turpentine to the level of the ,outlet 36. Thenthe chambers 16l and 17 may 'be completelydrainedwofwater (Which by reason of gravltal action Will be their only; contents,) by use of the outlets 31 and 39 respectivelynl f Also,'wl1en desired, the Water jacket of the chambers may be drained in any suitable manner, as by the valve 40 to prevent damage from freezing or for other purposes.

From the foregoing description it Will be apparent that We have devised a simple and effective condensing, separating and cooling apparatus by means of which practically a one hundred per cent. return may be secured from the distilling process, first, because of the positive recovery of the usual one-tenth vaporous Waste of turpentine and secondly because of the proper cooling and condensing of the turpentine to its normal specific gravity before barreling for shipment. The apparatus is practical y self-contained to carry out the three vsteps in a single receptacle or tank, and therefore embodies Within the limits of required space and parts of an old apparatus, the means effecting the complete recovery of turpentine spirits which has been described.
