TURPENTI NE SEPARATOR. APPLICATION HLED JULY 2. 1911- ABQHIBALD B. MARSTON, OF NEW\ ORLEANS, LOUISIANA.-

TURPENTINE-SEPARATOR.

Specification of Letters Patent.

Application filed July 2, 1917. Serial No. 178,195.

To all whom it may concern:

Be: it known that I, AROHIBALD B. MAR- sroN, a citizen of the United States, residin at New Orleans, in the parish of Orleans an State of Louisiana, have invented certain new and useful-Improvements in Turpentine-Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

The present invention relates to improvements in turpentine separators and re-condensers, and more particularly relates to improvements in apparatus for use in the gathering and separation of the condensates from the tail pipe, or discharge, of'the condensing coils in the process of distilling crude gum or. dip in the manufacture of turpentine and resin from the exudation of the pine tree. t 7

It is an object of my present invention to provide an improved. apparatus which will form a practical and eflioient means of increasing the yield of turpentine by preventing the loss by evaporation, and rendering superiorthe quality of the turpentine recovered for the reason that in my apparatus. the lighter fractions, which are ordinarily lost and which-are very valuable, are preserved. V

Heretofore it has been the custom to collect the condensates from turpentine stills 11%.0 en receptacles, allowing the tail pipes o t e condensers to discharge freely into the atmosphere and requiring the hot con; densates tofall'some distance through the atmosphere into the receptacles; thereby losing those lighter distillates, commonly called 'non-condensable vapors, and also losing. a certain percentage of recovered condensates through evaporation in the atmosphere.

Anotherobject of my present invention resides in conducting the separation and recondensation in a closed vessel to which the atmosphere will.not have access, and which will obviate the above disadvantages attendant uponthe gathering of the turpentine as now accomplished. a

It is a further object of my present invention to'provide an apparatus 1n which a sup'erior se aration of the water and turpentine will e effected, and in which the degree of pressure is maintained substantially con stant so that the action maybe substantially progress of the action.

uniformand the process therefore constantly practised with the same superior results.

In the accompanying drawings forming a part of this application,'and in which-similar reference symbols indicate corresponding parts in the several .views:

Figure l is a top plan view of an apparatus constructed in accordance with my present invention. I

Fig. 2 is a side-elevational view of the apparatus with parts broken away toshow the interior thereof; and y Fig. 3 is a sectional'view of a detail.

Referring more particularly to the drawings, which disclose one embodiment of my present invention, 1 designates a vessel 'which is closed by a tight fitting cover 2.

The cover 2 is formed with an opening into which is fitted a receiving casin 3, having a lower reduced end 4. A tail pipe 5, from a turpentine worm, projects into the receiving casing 3, preferably in the manner shown in Fig. 2, and conveys fromthe worm to t such receiving casing the condensates and non-condensable vapors. The lower reduced end 4' of the receiving casing 3 opens into the vessel 1 and carries han ers 6 for supporting ahorizontal bafile p ate 7, through which the separation of the turpentine and water is'greatly facilitated.

A- portion of the top of the receiving casing 3 is closed by a hinged glass cover 8, which has a'hasp 9 fittinjover an e e 10 for holding said cover '8 tightly c osed. Such glass cover 8. admits inspection of the 1, so that the attendant may observe the interior of the'receiving casing 3 and vessel The top of the receiving casing 3 carries" a fitting 11 which is shown more particularly in Fig. 3, and is provided to contain vacuum and pressure gages 12 and 13 and vacuum and, pressure valves 14 and 15. The vacuum valve 14 seats in an upward direction against a seat 16 under the influence of a coil spring 17 while the pressure valve 15 is adapted to rest on an under-seat 18, against which it is urged by a coil spring19. Both -valves 14 and 15 control access from the interior of the receiving cas'i'ng3 and'vessel 1 to the outside atmosphere.

The wateroutlet is provided by the pipe 20, the lower end of which terminates a short distance from the bottom of the vessel 1 wall of the vessel 1 just beneath the turpentine level, as indicated at 21. The turpentine level is indicated by the broken line AB,-while the water level or line of separation is designated by the broken line C-D.

A pipe 22 having its upper end disposed a short distancebeneath the cover 2 and approximately at the turpentine level A-B, provides for carrying oil the separated turpentine; said pipe passin through the wall of the vessel 1 near the indicated at 23, and being coupled to a second exterior pipe 24 which is arranged in an upright positlon on the exterior of said vessel 1 and rising to'a height just short of the open upper end of the inner pipe 22. A sight glass gage 25 -is carried by the pipe 24," and suitable drain cocks 26 and 27 are also provided. It-will be" seen more especially from .Fig. 2 that the pipes 22 and 24 form a trap.

J The operation of'theimproved apparatus is substantially as follows:

The condensates and non-condensable va-' pors from the worm are conveyed through the tail pipe 5 and discharged into the receiving casing 3 beneath the glass cover 8,

through which their entrance may be under observation of the attendant. Such condensates and va ors are directed as they issue from the tall pipe 5, down through the reduced lower end 4 of the receiving casing '3 and into the' vessel 1, where their introduction will be quiet, due to the'presence of the baflie plate 7 which is disposed directly in the path of such incoming products, and which causes the same to pass in all directions into the liquid in the vessel 1 with a f vessel 1, will operate to force the water minimum of disturbance, whereby not to interfere with the rogress of'the separation which is constanty takin lace therein. As these products are thus db lvered to the vessel 1, due to the difl'erences in their specific gravities, the water will seek the bottom while the turpentine will rise 'to the top, the, line of separationbetween the two llquids being that shown at CD. The weight of the combined liquid in the through the lower end of the discharge pipe 20, and'out through the connection made at 21, from which point the water may be led to,

a suitable destination.

The normal level of the turpentine is that shown at AB'in' Fig. 2, and this level will be constantly preserved by .the presence of the open upper end of the turpentine outlet pl pe 22, which carries ofl the separated and eed turpentine and conducts the same through the connection 23 to and through the pipe 24 to a'turpentine receptacle provided to receive same. I

The gage glass 25 indicates the water level or the line of separation between the water bottom thereof, as r The interior walls of the receivin casing 3 provide a large surface on which 1: e noncondensable vapors may have every opportunity to condense and pass downinto the vessel 1, where they will unite with the turpentine therein, which turpentine will be greatly improved by their addition.

It is of the greatest importance that the pressure Within the receiving casing 3 and vessel 1 be substantially uniform, and that no abnormal vacuum or increased pressure be permitted to obtain therein at any stage of the operations, as such will affect the proper separation of the liquids and the speedy action of the apparatus; and for this purpose the vacuum valve 14 and pressure valve 15 are provided. I

Whenever a predetermined degree of vacuum tends to exist within the apparatus, the atmospheric pressure acting on the valve 14 will unseat the same and permitan. inrush of atmospheric air to relieve such abnormal degree of vacuum and to restore the apparatus to normal working conditions. The degree at which the valve 14 may open is controlled by the strength of the coil spring 17 which may, of course be selected to give the proper results, On the other hand, should the pressure in the apparatusbecome excessive, such pressure will unseat the valve 15 against the atmospheric pressure thereon,

together with the strength of the coil spring valve 15 will be seated by the spring 19,

which may be of any strength in accord,- ance with the pressure required. Of course other types ofvalves than the check valve shown in Fig. 3 might be employed for this purposewith equally good results, and I do not wish to be limited to this or any other particular type of valve. I

The location of the baffle plate-7, together with the relative-locations of the water and turpentine outlets, may be rearranged in accordance with the specific gravities of the liquids to be separated, in this manner insuring perfect separation.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as maybe required by the claims.

I claim:
