SEAL FOR HYDRAULIC MAINS.

SPECIFICATION forming part of Letters Patent No. 400,333, dated March 26, 1889.

Application filed December 8, 1888. Serial No. 293,032. (No model.)

To all whom it may concern-.-

Be it known that I, ROBERT HABERTHI'J'R, of the city, county, and State of New York, a citizen of the United States, have invented certain new and useful Improvements in Seals for Hydraulic Mains, of which the following is a specification.

This invention relates to an improved seal for the dip-pipes of hydraulic mains, whereby the dip-pipes may be sealed in the usual manner when the retorts are being charged or the dip pipe unsealed Whenever the free escape of gases generated in the retorts is desired; and the invention consists of a hydraulic main in which the dip pipes enter through the bottom of the main and above the level of the liquid in the same, and of an inverted sealing-cap that extends over the upper open end of the dip-pipe, and can be raised or lowered by a U-shaped rod passing through a guide-pipe, the lower end of which is sealed in the main,said rod being operated by a lever pivoted to the upper end of the rod, which rod is held higher or lower by means of a friction-spring.

In the accompanying drawings, Figure 1 represents a front View of a bench of gas-retorts with my improved seal for hydraulic mains arra'iged in connection therewith. Fig. 2 is a vertical longitudinal section of my improved seal for the dip-pipes of hydraulic mains. Fig. 3 is a vertical transverse section of the same on the line 00 00, Fig. 2.

Similar letters of reference indicate corresponding parts.

A A in the drawings represent the retorts of the gas-bench; B B, the dip-pipes, which connect the retorts with the hydraulic main 0, said dip-pipes entering the main through the bottom of the same, as shown in the drawings. The dip-pipes B have their upper sections made angular, so as to make connection between the vertical section of the dippipes and the bottom of the hydraulic main, and said pipes are each provided at one angle with a detachable lid, B, on the under side, which lid is retained and held in position by a suitable clamping device, B

I the dip-pipe B extends above the level of the liquid in the main, and is removed by an inverted sealing-cap, D, which can be raised or lowered into the liquid. by means of a U- The end of V shaped rod, E, that is guided in a fixed pipe, F, which is screwed into the top of the main 0, said rod being pivoted to a lever, F, which or ears F on the rear of the hydraulic main 0, as shown in Fig. 3. The front end of the lever F is operated by means of any suitable handle, (not shown,) by which the lever, and thereby the sealing-cap, can be raised or lowered. The lever and sealing-cap are retained in the raised or lowered position by means of a friction-spring, H, that is attached to the pivot of the lever F and U-shaped rod E, the free end of the spring bearing on the inner surface of the guide-pipe F, as shown in Fig. 2. Whenever the lid of the retort is opened, so as to charge the same, the sealingcap is lowered into the liquid in the main, and thereby the hydraulic seal established, so that no air can pass through the retort in the hydraulic main. When the retort is charged, the lid closed, and the gas is being generated in the retort, the sealing-cap D is raised, so that a free escape of gas is established, and thereby the quicker and more effective working of the bench obtained. The sealing-cap may also remain in submerged position in the liquid, as the gas has suflicient pressure to force its way through the seal in the usual manner. hen, however, a sufficient generation of gas takes place, then the sealing-cap is raised out of the liquid, so that the free discharge of gas into the main takes place. The bench may thus be worked entirely under seal in the usual manner, while the retorts of another bench may be worked without sealing; or any retort may be changed from the sealed to the unsealed condition in a few moments. As the dip-pipe is not extended above the hydraulic main and then downward again into the same, but connected directly through the bottom of the main and extended upward in the same, a considerable saving in the length of the dip-pipe may be made and the gas conducted into the main in an easier manner, as the angles-of the pipes and not oblique, as in the dip-pipes heretofore in use.

Having thus described my invention, I claim as newand desire to secure by Letters Patent- The combination, with a hydraulic main, of
