CHARLES B. CLARK, OF BANGOR, MAINE.
Specification of Letters Patent.
Patented April 9, 1907.
Application filed March 3.1906. Serial No. 304,049.
1'0 all whom it In/a4, concern.-
Be it known that 1, CHARLES B. CLARK, a citizen of the United States, residing at Bangor, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Sectional Tubular Gas- Coolers, of which the following is a specification.
My invention consists of an improved sectional tubular gas-cooler, and is fully illustrated in the accompanying drawings, in which Figure 1 is a plan. tion.
Similar letters refer to corresponding parts throughout the figures.
The coolers in common use are lead boxes with lead-burned joints or seams and are submerged in water. These lead-burned joints are very liable to become leaky and to admit water and air, which necessitates shut-downs and expensive repairs. These coolers are also di'llicult to reach when repairs are necessar The object of my invention is to provide a cooler which need not be submerged, so leaving the parts easily accessible for repairs, without lead-burned joints, and formed in sections which, in case of accident to any section, will permit the ready substitution of a duplicate part.
In construction I provide a series of inverted-V-shaped sections, one of which is shown at Fig. 2. Each section consists of a pair of lead tubes A A, coupled at their bases to lead header-pipes B B and having their tops inclined toward each other, but not actually contiguous. To the tops of the tubes is coupled a hollow leaden elbow C, shaped like an inverted V, with the apex of the V open and surrounded by a flange c. The opening at the apex is closed by a heavy leaden cover D, with handle d, designed to fit smoothly over the flange c, and to make the entrance or air or water impossible a thin layer of paint or cement may be spread between the flan e and the cover. The whole is conveniently placed between the furnace, where the sulfur is burned, and the lime-water tank and below a sprinkler of sufficient size and capacity and Fig. 2 is an end elevais mounted upon a supporting-frame F. Any number of sections may be used, as may be deemed advisable, and the covers D may be detachably oincd to the apex of the elbow in any convenient manner.
In operation, as shown in Fig. 1, the gas from the furnace is introduced into the header, pipe B at l) and passes thence up into the tubes A, rises therein and passes down through the tubes A into the header-pipe B, whence it passes through a second battery of similar tubes X X and emerges at m, whence it is conducted to the lime-water tank, all the sections of the cooler having been continuously drenched with cold water during the passage of the gas, and the gas when it passes out of the cooler being sulliciently reduced in temperature.
The advantages of my device, as previously indicated, consist in the fact that the cooler is not submerged, and hence can easily be reached for repairs; that it has no leadburned joints or seams, that the covers D can be instantly removed and access had to the interior of the tubes, and that any partial or complete section can be removed in case of accident and a duplicate part quickly substituted.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is
In an apparatus of the class described, a
tubular header members spaced apart and each provided with a plurality of spaced branch pipes converging inwardly and upwardly and each opposite pair'thereof united by a tubular member open at the upper end, and a detachable closure for each of said openings, whereby the product to be treated is received into one of said header members and caused to transverse upwardly through one series of said inclined branch pipes and downwardly through the other of said series of inclined branch pipes and discharged from the other of said headers.
