FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent Nol 291,538, dated January 8, 18.84.
Application filed November 24, 1882. (No model.)
.To all whom it may concern.' Be it known that I, WILLIAM ROLLAR, a
citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed-Water Heaters for Boilers, and I hereby declare the following to be a full, clear, and exact description of the same. 1o Divested for the present of all minor details y of construction, a general description of my improved device, its method of operation, and the results accomplished is as follows: Within a strong metallic cylinder or shell, which may be either vertical or horizontal, having an inlet-pipe at one end connected to the steamexhaust of the engine, and having an outlet at the opposite end, I support a worm a little smaller in diameter than the interior of the cylinder, and extending nearlyor quite from end to end of the same, with an inlet and an outlet, preferably both, at the same end of the cylinder, the former leading from the feed pump, and the latter leading to the boiler. I also employ, suspended centrally within the coil, a hollow sheet-metal cylinder of smaller diameter than the interior'of the coil, also somewhat less in length than the coil, thus making it shorter than the interior of theshell, and preferably having that one of its ends which is adjacent to the steam-inlet of the cylinder made conical. Vith this construction the exhaust-steam fromnthe engine, entering the cylinder, iiows through the same in contact with the coil oi' pipe, through which the feed-water circulates on its way to the boiler, thus heating the water to ahigh temperature. The steam, having performed its work, finds Vits way out, considerably condensed of course, through the outlet provided for that purpose. The effect of the interior suspended cylinder operating in conjunction with an inclosingcylinder is to cause the hot steam to impinge with more force upon the interposed coil than 45 would be the case if it were omitted. The
. conical end of this cylinder tends to divide the steam without resistance.
My invention, as may be derived from the foregoing outline, consists, first, in employ- 5o ing, in a feed-water heater, a worm for the passage of the feed-water, inclosed withina cylinder through which the exhaust-steam passes, and combining with theinclosing-cylinder and worm, as above, a suspended interior cylinder of smaller diameter than the worm, and shorter than the interior of the shell. A
It consists, also,in certain details of construe tion and combinations of parts, all as hereinafter more fully set forth.
In the drawings, Figure l is a central longi- 6o tudinal section of my device, and Fig. 2 a transverse section on the line 2 2 of Fig. l.
A is the inclosing cylinder or shell, which I make light'and strong, of wrought-iron, and 4 B the worm, which I prefer to make of cop- 65 per tubing, supported within the shell. .'Io support the worm in position I employ three bars, o, connecting the heads u of the shell by being firmly securedthereto by nuts t, and so disposed as to touch each coil of the worm at 7o three equidistant points. The worm is secured to these bars by means of metal strips s on the inside of the worm, firmly attached to the bars u above and below the worm, and also between the consecutive coils thereof, by means of nut-bolts r, which operate to draw the strips closely about the tubing, as shown.V The inlet and outlet of the worm are both at the upper end of the shell when the latter is vertical, as represented in the drawings, the pipe pass- 8o ing down in a coil from the inlet, and then back in a straight line inside the coil to the outlet. At both the inlet and outlet it is coupled to a pipe on the outside of the head by 'a suitable coupling device. The steam is ad- 8 5 mitted into the cylinder by way of the pipe h and discharged by way of the pipe z'. n When the cylinder lies horizontally, the drip-pipef will of course be placed upon the lower side instead of upon the lower end,as shown. The 9o interior cylinder, D, is secured in position by means of metal braces g-three at each en deach bolted or riveted to it,as shown, and connected at its outer end to` the adjacent bar xv by one of the nut-bolts r, which fasten the g5 strips s to the bars.
By the construction above described, the weight of the heater in proportion to its size is reduced to the minimum, all joints and connections are outside and easy oi' access, and. 1GO
the device Works equally well Whether horizontal or perpendicular, and can be set up in a corner or swung under the floor, out of the Way.
fhat I claim as new, and desire to secure by Letters Patent, is-
1. In a feed-Water heater, the combination of the shell A, having an inlet and an outlet pipe for the passage ofthe exhaust-steam from the engine, worin B, supported within the shell, and provided with an inlet and an outlet through the shell,for the passage of the Water on its Way to the boiler, and the cylinder D, suspended Within the confines of the Worm, and shorter than the interior of the shell A, substantially as described.
2. In a feed-Water heater, the combination of the shell A, provided with an inlet and outlet for steam, worin B, inclosed within the l shell, and provided With an inlet and outlet through the shell for Water, bars c, extending` longitudinally through the shell, and secured to the heads thereof, and the strips s and nutbolts r, securing the Worin to the bars c, substantially as described. 4
3. In a feed-water heater, the combination, lwith the shell A, having an inlet and an outlet pipe, Worm B, provided with an inlet and an outlet through the shell, barsV c, extending longitudinally through the shell, and secured to the heads thereof, and the metal strips s and nut-bolts r, securing the Worm to the bars c, of the conical-ended cylinder D and braces g, substantially as described.
