ALEXIS THIRAULT, OF NEW YORK, Y;

Letters Patent 1V0. 61,120, dated January 8, 1867.

IMPROVEMENT 1N DISTILLING PETROLEUM.

Be it known that I, ALEXIS TILIRAULT, of the city, county, and State of New York, have invented a new and useful Machine or Apparatus for Distilling Petroleum Oil; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawing, makin a part of the specification, in which:-

Figure 1, in plate 1, represents a front view of the apparatus.

Figure 2, in same plate, the top view of a tar-cock.

Figure 1, in plate 2, a perspective view of the apparatus and Figure 2, in same plate, atop view of the same.

A B O are three different-sized boilers, forming a still, connectedtogether, the use of each of which is as follows: The boiler A is employed for the purpose of heating the crude oil arid separating the benzine from the same, before it is allowed to enter into the boiler B. The boiler B is employed for distilling continually the oil, which is allowed to flow into it from the boiler A. The boiler G is used for the purpose of redistilling certain colored parts of oil, which would flow out of the boiler B undistilled, on account of the pressure the oil sometimes undergoes in its passage from the boiler Ainto' boiler 13, and which colored parts of oil, after being prevented, by means of a cock, from mixing with the clear oil previously distilled, are'forced into boiler C for redistillation. D and E are tubs to receive the oil after it is distilled. F is a tar-cock, the use of which consists in enabling to clear the still of the tar and residuum remaining in it during theoperation without stopping the distillation. It consists of a pipe, H, of about three feet in length, placed at the bottom oflthe boiler B, which pipe H encloses a square iron rod, G, attached to the plug of the cock F. This iron rod penetrates into the still, for the purpose of breaking and removing the dry residuum remaining in the pipe H, thereby securing free egress for the tar. In connection with the pipe H there is another crooked pipe, K, communicating at one end with the cock F, and at another end with another cock, J, which is joined to the pipe H as near the still as possible, which cock J is only opened to allow the tar to follow through the pipe K after the residuum has been broken by the square iron rod attached to cook F, and this cock F being left open, to allow the tar and residuum to flow freely into the iron box or cylinder L, where it will cool by means of the refrigerator N. M is a small, crooked pipe, to regulate the pressure of the air in the iron box L. O is a cock toempty the box L. P is a tub for receiving benzine from the still. Q, ditto water. R, condenser for oil and hen-- zine. T, pipes for the escape of the gas from the different parts of the still. U, hot-air chamber conveying the heat to the bottom of boiler A. V, hot-air pipe. W, arch or cylinder for the hot air at the bottom of part B. The construction of the boilers A B and O is such as to leave an open space between the bottom of the boiler A and the top of boilers B and C, the space being called a hot-air chamber, U. The object of this chame her is to convey the heat to the bottom of boiler A and to the top of the boilers B and O, in connection with the hot-air space surrounding the whole still. At the side ofthe boiler B are two cylinders or pipes, V, and at the bottom of the same boiler is an arch or cylinder, W, being both passing through the entire length of the boiler B, the arch or cylinder W being in connection with the hot-air passage Y, at the centre of the arch of the furnace Z, and also with the hot-air space surrounding the entire still, the object of which is to prevent the direct action of the fire in the bottom of the still, and for regulating the heat, by means of dampers placed in the brick-work in front of the arch cylinder. X, man-hole si Y, hot-air passages. Z, furnace, brick-work, e'tc. No. 1, pipe, with siphon, cock, and gas pipe, to fill boiler A with crude oil. No. 2, pipe, with siphon, cock, and gas pipe, to lead the boiling oil from boiler A into boiler B. No. 3, pipe, with siphon and cooks, to draw the water from boiler A. No. 4, four connecting leading pipes and serpentine, for the escape of burning oil. N0. 5, pipe and serpentine, for the escape of bcnzine. No. 6, gauge-cock, with siphon and gas pipe, for boiler A. No. 7, gauge-cock, with siphon, for boiler B. No. 8, pipe and cock leading the oil from the receiving tub D into the receiving tub E. No. 9, pipe, cock, and siphon, to lead the colored oil into boiler C. No. 10, escape pipe and serpentine, for the redistilled oil from boiler C.

The operation of the apparatus is as follows: I first fill the boilers A and B with crude oil, through the pipes Nos. 1 and 2. After the benzinc or naphtha has escaped from the boiler B through pipe No. 4, and (that contained in A through pipe No. 5, I send the contents of boiler A into boiler B through the pipe No. 2, being guided by the gauge-cock No. 7; and after boiler A has been emptied into boiler B, I again fill boiler A with crude oil, and prepare it for boiler B by separating the benzine from it, nnd then allow it, as before, to flow into boiler B through pipe No. 2, thereby securing a continuous distillation; When, on .account of the pressure the oil sometimes undergoes in its passage from boiler A into boiler B, it flows outcolored through pipe and serpentine No. 4, I prevent it from mixing with the oil already distilled by closing the cock 7 of the receiving tuh D; then, by opening the cock of the pipe N0. 9 I cause the oil toflow into the boiler C, where it is redistilled and allowed to flow out through pipe No. 10 into'the receiving tub E. When I judge it noees'sery to take out the ter and residuum from the still, I slacken the fire for a moment, causing thereby the boiling oil to rest and the tar to depose in the bottom of the still, end then I cause the tar and residuum to flow out of the, still, by means of the tor-cock F, in the manner hereabove describedtin the construction of'the said cock F.

C'laz'm.

What I claim as my invention, and desire to secure by Letters Patent, i5

1. The apparatus constructed as above described, the object of which is to secure a continuous distillation by one single operation, being a combination of boilers A B O and the tor-cock F with the hot-air ohnmber U, and all the pipes and other ports composing the said apparatus.

2. I claim separately as my invention the still composed of boilers A B O as to their form nnd combine tion, for the use and purpose above described.

3. I claim separately as my invention the tar-cock F, as to its construction, the object being to eleer the still of all residuum without retarding the distillation. I

A. THIRAULT.
