TURPENTINE-RETORT.

Application filed Apri121, 1913.

To all whom may concem:

Be it known .that I, J OSHUA G.. GARD ER,

i a citizen of th United States, residing at Daytona, in the county of Volusia and State of Florida,' have inven'ted new and useful Improvements in Turpentine-Retorts, of which the following is a specicaticn.

This invention rela-tes to turpentine stills or retorts and particularly to the joint formed between the cage or basket and the inner portion of the head of the still or retort body or casing, and the primary object of the invention is to provide simple and`effective means for forming a tight joint between the upper portion of the cageor basket and the inner part of thei head or .rim of the retort body or casing principally through the weight imposed by the cage when loaded or charged to prevent leakage or escapeof any vapors through the joint between the two parts and at the same time provide for a ready separation or disjointure of the basket or cage from the casing when it is desired to remove the basket logous devices or cage from the still or retort to diharge the contents of the same.

A further object of the invention is to provide simple and eifective means at the interier of the rim of the 'basket or cage for engagement of the grab hooks of hoisting nechanism to facilitate the removal and discharge of the basket or cage. A

The invention consists in the Construction and arrangement of the several parts which 'Will 'be more fully hereinafter described and claimed.

In the drawing: Figure 1 is a sectional View of a still or retort embodyingthe features of the invention and showing the basket orcarrier also broken away in part and in section. Fig. 2 is an enlarged detail section, through a portion of the head of the still or retort and the rim of the basket or carrier. Fg. 3 is aplan View of a portion of the basket or carrier particularly showing the'rim and the opposed devices for engage. ment by the grab hooks, of the' histing mechanism. Fig. 4 is a transverse vertical section on the line 4-4, Fig. 3. t i

The numeral 5 designates the outer body' or casing of the still or retort constructed of metal of suitable' thickness and having an annular head 6 provided with a hinged cap or cover 7 and. releasable hook bolts or ana- 8 for secu'ring the said cap in Specification of Letters Patent.

closed position. The-body or casing 5 is provided with a suitable outlet pipe 9 in the bottom thereof, the said pipe having a valve 10 and a thermometer ll to determine the temperature of 'the fluid passing through the pipe At a suitable elevation above the bottom of the body or casing 5 a valved outlet pipe 12 is attached and leads to a condenser 13, and above the outlet pipe 12 is an injecting pipe 1.4 which is also provided with a valve 15 for the purpose of cleaning out 'the retort or still by the injection there- Connected to the top or cover .7 is a valved stearn inlet pipe 16.' The function of all of these inlet and outlet pipes is fully and clearly' disclosed in my copending application Serial No. 755,'734, filed March 20, 1913. y

The features of the present invention reside in the joint formed between the. rim 17 or carrier 18 and the head 6 of the body or casin'g 5. The head' 6 has an wardly opening groove 20 which is gradually reduced toward its lower or base portion 21 and has an inner upwardly -tapered or reduced guard flange 22. The rim 17 is formed with i an irregular ing an outer tapered fiange 24: of reduced thickness and an inner overhangin tapered fiange 25 of greater thickness and less length or dependence, both flanges 24 and 25 having their terminals projected downwardly. The flange 24 conforms in contour to the groove 20 of the head 6, and in the said groove a suitable yielding packing 26 is disposed and may be of `any material adapted for the purpose of either a fibrous, 'granular or sheet character, and when the basket or carrier 18 is disposed within the retort the fiange 24 engages the said packing and seats itself by compressing the packing, as shown particularly by Fig.' 2, and automatically produces a tightly sealed joint which will prevent the escape of va pors between the head 6 and the rim 17 respectively of the body or casing 5 and the basket or carrier 18. At diametrically opposite points the flange 25 of the head 23 'is formed with extensions or lips 27 for engagement therewith of grab hooks or other devices on' the lower extremity of a hoisting eable usually employed'with stills or retorts tott 'or to place' said basket or: carrier in T-head 23 havcarrier from the rev proper position within the retort. 'In View through the medum'of the interposed packing 26, forthe reason that the said fiange 24: is caused to sinkinto and tightly engage and at the same time compress the packing i i material 26, and owing to the formationof the groove or channel 20-in the 'upper por: tion of the head 6 or so that it Will open -upwardly, the head 23 of the' rim 1 7 together with 'the fiange '24 maybe readily disengaged from 'the groove 'or'channel 20 and the pcking 26 without displacing the said packing.

The packing material 26 may be replaced at any time and is readily reached from the upper portion of the retort or still when the cover 7 is' open.

The improved features hereinbefore disclosed will be found of material advantage in the effective operation ofthe retert or still and are anplicable to all forms '0% stills wherein it is desirable' to force the steam or other fluid downwardly through a charged basket or carrier to cause the vapors to rise between the basket or carrier an'dthe body or. casing of the retort or still and be' carried ofi' at the 'side of the retort or still toa condenser or otherdevice -\Vh. at is claimed is: u

1. In a retort of the class specified, the combination of a retort body having an annular head With an inner annular ledge adjacent to the top edge of the ledge and provided with an upwardly opening groove, a basket or carrier having a head with a' rim which extends both outwardly and inwardly from the' head to 'form inner and outer fianges which are undercut or grooved, the I outer fiange of the rim being at a higher elevation than the inner flange thereof so as 'to-engage the groove in the annular ledgeof the head of the body, the inner portion of i the said ledge being of such shape as 'to fit snugly against the outer wall of the head of be readily associated'` With and detached from the flange 25, with x 'ing arrim of approximately mama? the basket or carrier to forma tight joint and a compressble paeking material interposedletween the outer fiange of the basket rim and the wall of=the`groove of the annular ledge, said packing automatically con: forming to and remaining in the shape of the groove' and providing a seat for the fiange by the weight of the basket imposed thereon.

2. In a retort of the class specified, thei combination of a retort'body having ahead with an inner annular ledge near the upper edge thereof formed 'with an upwardly opening groove, the inner portion of the ledge adjacent to the groove being 'vertieally straight and the inner top portion of the wall of the groove being regularly curved', a basket having an approximately T-shaped head Secured to the upper portion thereof to form a rmwith inner and outer flanges which are undercut, the outer fiange snu'gly fitting 'over the inner upper portion of the groove in the wall of the ledge and the inner part of said ledge closely hearing against the outer side of the upper portion of the basket head to form atight joint, and a yielding packing means inserted in the groove of the ledge and engaged by the outer flange of the head of the basket; L

3. In a reto'rt of the class specified. ,the

combination of a retort body having a head with an inner grooved ledge` a basket havto provide an outer continuous depending fiange to engage the groove in the head and also provided with means at theinner portion thereof for engagement of parts of hoisting apparatus wherebyrthe basket may be readily withdrawn from and placed in the retort body, and a yielding packing removably disposed in the ledge groove and engaged by the outer flange of the basket tight. joint between the rim and the ledge, the basket rim and the inner portion of the ledge also having tight en-' gagement with relation to each other to prevent leakage therethrough.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses( J OSHUA G. GARDNER.
