IMPROVEMENT IN C-AS-VIIRKS` HYDRAULIC MAINS. l
Specification formlngpart of Letters Patent N0. 137,655, dated April 8, 1.873; application filed November 18, 1872.
To all whom it may concern:
Be it known that I, PETER T. BURTIs,of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hydraulic Mains for Gas-Works, of which the following is a full description, reference being had to the accompanying drawing making a part of this specification, and consisting of two sheets, in which- Figure 1 is an end elevation, showing the gas and tar pipes in section; Fig. 2, a front elevation; Fig. 3, a plan 5 Fig. 4, a longitudinal section of my expansion-joint; Fig. 5, an elevation of the gland detached; and Fig. 6, Sheet 2, shows a front elevation oftwo benches of retorts, each connected with a separate hydraulic main; showing also connectingpipes, gas-pipes, and tar-pipes, the standpipes of one bench being broken away that the other parts may be more clearly represented.
As gas-works have been heretofore constructed the hydraulic main has been a single continuously-connected pipe without regard to the number of benches of retorts used. It is desirable and necessary that the main be perfectly level in order that the seals may be uniform; but the expansion and contraction of the brick-work, and parts connected therewith, render it difficult to keep it in such position, especially when a portion of the benches become cool, not being in use 5 .and by contraction the main is liable to be broken, and a section of the main cannot be taken out andv replaced, nor can permanent repairs to any extent be put thereon without stopping the benches, and the main cannot be cleaned while any of the benches are in use.
My invention consists in providing a detached and separate hydraulic main for each bench of retorts, the main of each having no connection or direct communication with the mains of the other benches of retorts; in providing a gas-pipe and tar-pipe for all the benches of retorts in a section of the works 5 in so connecting each main of each bench with such gas-pipe and tar-pipe that such main can be thrown out of use or removed without interfering withA the use of the other mains; andinl the several devices and com! binations hereinafter claimed.
In the drawing, A represents a hydraulic main for a single bench of retorts,; X, stand pipes passing from the retorts to the main 5 (l, gas-pipe5 B, pipe leading from the main to the gas-pipe; D, valve to shut off or open communication with the gas-pipe C; E, tarpipe 5 It, cup on the top of the tar-pipe communicating therewith; S, siphon through which the tar from the main A flows into the cup R 5 and F, my expansion-joint applied to the pipes C or E. This jointF is represented in Fig. 4, in which H is a pipe with a socket, I, cast upon it, within which is a shoulder, c, either cast with ,it or inserted thereon. K is the spigot end of another pipe, somewhat enlarged, and turned so as to permit the collar or gland W to work freely thereon, packing will be held rmly in place between the inner end of the collar or gland and the shoulder o. The two parts of the joint are held together by stud-bolts and nuts at the points b, Fig. 5.
I thus form a joint which, while it will se-l curely retain the gas or tar, admits of eXpansion and contraction, as the pipe K. can move within the socket a distance equal to that between the inner end of K an'd the .shoulder c of the socket.
As represented each main is made of several pieces, properly bolted and secured together; but each hydraulic main might be cast in a single piece with suitable openings for the several pipes and with a hand-hole. The ends of the pipes X extend down into the main and are sealed in the usual manner.
In operation the products of distillation from each bench of retorts passes directly into a separate and independent hydraulic main, A, from which the gas passes through the connecting-pipe B into a common gas-pipe, C, while the tar iows through the siphon S into a continuous tar-pipe, E.
By means of avalve, D, connection between the gas-pipe C and any one of the hydraulic mains A can be cut ol at pleasure, so that such main and the bench of retorts with which it is connected may be out of use, while all the other benches of retorts and all the other hydraulic mains are still in use.
main be injured by such expansion and con-- traction.
rEhe flexible joint permits considerable con-` traction and expansion of the gaspipe Without injury thereto. This joint is not as essential for the tar-pipe as for the gas-pipe, because the former is subjected to less heat thanthe latter.
What I claim as new is as follows:
1. The combination of the separate hydraulic mains A with the gas-pipe C and tarpipe E, in gas-generators where more than one bench of retorts is used, substantially as specified.
' 2. The combination of the cnt-ofi' valve D and pipe B with the main A and gas-pipe C, so that either bench or main can be thrown out of use without interrupting or interfering with the gas-pipe or the other benches7 substantially as described.
3. The expansion-joint F, in combination with the gas or tar pipe for equalizing the eX- pansion or contraction of such pipes as different sections are brought into or thrown out of use, substantially as set forth.
4. The siphon S,'in combination with the main A and tar-pipe E, substantially as and for the purposes specified.
