WATER-HEATER FOR LOOOMOTNKES.
T6 all whom, zit mhy cmwern: v
Be it known that I, DAVID W. CUNNING- HAM, acitizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Water-Heater forLoconiotivaBoilers, of
which the following is a specification.
The object of my invention is to provide a water-heater of simple, durable, and inexpensive construction designed to utilize the steam and hot water discharged from the blow-off pipes of locomotives for heating water for cleaning locomotives and refilling their boilers; and,-more specifically, it is my object to provide a' device of this kind in which the blow-off steam and water will be utilized to its maximum efficiency in heating the water to-be used in cleaning and refilling the locomotiveboilers.
"My invention consists in. the construction, arrangement, and combination of the various parts of the'device whereby the objects contemplated are attained, as hereinafter more 1 fully set forth, pointed out in my claims, and
illustrated in the accompanying drawings, in
which--,
Figure 1 shows a vertical longitudinal sectional view of the complete heater embody,- ing my invention. Fig. 2 shows a front end elevation of same. Fig; 3 shows a sectional view onthe line 3 3 of Fig. 1, and Fig. 4 shows a. detail View illustrating one of the gatev'alves of the cleaning-out pipes.
-Referring to the accompanying drawings, the heater is composed of a main cylinder 10, having cylinder-heads 11 at both ends and also having transverse partitions 12 spaced apart some distance from the cylinder-heads. These transverse partitions support the boiler-tubes 14, which communicate with the chambers at the ends of the cylinder between the partitions and the cylinder-heads; Mounted on to of the cylinder are the support- .ing-brac ets 15, and resting on said brackets is the su 'erheating-cylinder 16, having the cylindereads 17 therein and also having the transverse partitions 18 spaced apart from the heads 17 to form chambers.
The reference-numeral 19 indicates a steam and water pipe to receive the steam and we ter from the blow-off pipes of a locomotiveboiler. This pipe 19 communicates with the chamber 20 at the front of the cylinder 10. Leader; from the bottom of the chamber 20 is 'a cleaning-out pipe 21, provided with a Specification of Letters Patent. Application filed July 6,1906; Serial Ho. 325.395
gate-valve of ordinary construction, which Patented March 19, 1907.
gate-valve is clearly illustrated in Fig. 4. 'A'
similar cleaning-out pipe communicates with the chamber23 at the rear of the cylinder 10, and a drain-pipe '24 is connected with the said cleaning-out pipe-above the gate-val\-*e therein. This drain-pipe 24 extends up-, wardly toa point above the center of the cyl inder 10 and then downwardly and is provided with an air-vent tube 25 at its upper portion. In this way the water-level of the cydinder 1.0 is maintained at the level of the upper portion ofthe said:drainipe, and siphonage ofthe water-through t e drainpipe is prevented b the air-vent tube 25.
Ihave arranged or providing communication' between .the chamber 230i the main cylinder and the chamber 26 of the superheater-cylinder by means of the pipe '27, and I" have provided for discharging the steam after passing through the tubes by the steamdischarge ipe 27, which communicates with the chain er 23 at the front of the superheater. The chambers 26' and 2S of the su-' perheater communicate by means oi the tubes 29, which ass through the partitions 18. the main cylinder and the artitions 18 of the superheater-cylinder are :6 led. with water by means of the water-inlet pipe 30 at the bottom of the cylinder 10. Communication is established between the water-chambers of the two cylinders by means of the pipe 31,
and the heated water may be withdrawn from' the top of the superheater through the pipe 32. In practical usethe blow-oii pipe of a locomotive-boileris connected with the pipe 19,
-and, assuming that the water-chambers of the cylinders have; been previously filled with water, the steam and water from the pipe .19 will enter the chamber 20 and the water will drop to the bottom of said chamber, while the steam will rise to the top, and-both Will flow through the tubes 14 to the chamber 23 at the other end. The water will remain in The spaces etween thepartitions 12 of said tubes and impart its heat to the water surrounding the tubes, while the steam will rise through the pipe 27 to the chamber 26 arran ed as shown the water-level in the chain ers 20 and 23 and their connectingtubes is always maintained at the level of the top of the drain-pipe, so that there is plenty.
of room above the water-level to permit the passage of steam through the upper tubes,
and then flow through the tubes 29 to the and the cooledwater at the bottom of the chamber 23 will pass out through the drain.-
pipe, as the heated water from the locomotive-boilerr enters the front chamber 20, so that practically all of the heat from the water of the boiler will be utilized in heating the water within the heater. If it is desired to clean out the sediment that maygather in the bottom of the cylinder 10, the valves 22 may be opened and all'of the water con tained within the tubes and the chambers be discharged through the pipes 21. By thus causing the steam and hot water from the locomotive-boiler to pass back and forth through the. tubes in close contact with the water in the cylinders the said water in the cylind' rs is quickly heated, and shortly after the water and steam have been blown from a locomotive-boiler the operator may connect a pipe with the pipe 32 and use the water in the heater for Washing out a locomotiveboiler, and after it has been washed out he may then refill the locomotive-boiler with hot water, so that shortlyafter a fire is started in the locomotive fire-box steam may be obtained and the locomotive be readyfor use.
By means of my improved heatin device a locomotive may be cleaned out an refilled and ready for use in a comparatively short time and with comparatively little work, and by usin hot water for cleaning the locomotive-boi ers all undue contraction of theaffected parts is avoided. In places where cold water is used for this purpose there is often considerable damage done to the boiler and boiler-tubes.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefior, is-
1. In aheater of the classwdescribed, the combination of a heater-body having closed ends, partitions within the body spaced apart from the ends to form compartments at the ends, tubes extended through the body portion and communicating with the chambers at the ends, a blow-off pipe communicating with the chamber at one end, a steam-discharge pipe communicating with the chamber at the other end, and a drainpipe communicatin with the bottom of one of the chambers an extended upwardly to a point near the center of the heater-body and then downwardly and having a vent-opening near its upper portion.
2. In a waterheat'er for locomotive-boilers, the combination of a main heater-body and a superheater-body connected with each other and each having closed ends, partitions within each body portion spaced apart from the ends, tubes in each body portion communicating with the chambers beyond the partitions, a blow-ofi' pipe communicating with the chamber at one end of the main body portion, a steam-pipe communicating between the ends of the main heater and the superheater-body portions opposite from the blow-off pipe, a steam-discharge pipe communicating with the chamber at the other end of the superheater, cleaning-out pipes communicatin with the bottoms of the chambers at the ends of the main body, a water-inlet pipe communicating with the bottom ofthe main body, a pipe communicating between the body portions of the heater and the superheater, a water-discharge pipe communicatin with the top of the superheater and a rain-pipe connected with one of the cleaning-out pipes extended upwardly ,to a point near the center of the heater body and then downwardly and formed with an air-vent opening at its upper portion.
3. In a heater, of the class described, the combination of a heater-body having closed ends, partitions within the body spaced apart from the ends to form compartments at the ends, tubes extended through the body portion and communicating with the 'ohambers at the ends, a blow-off pipe communicating with the chamber at one end and designed to conduct steam and water from a locomotive-engine to said chamber, a steamdischarge pipe communicating with the pipe at the other end and a drain device leading from one of said chambers and arranged to prevent ,the escape of water or steam from the chamber when the waterlevel is below the central portion of the chamber and to emit the escape of water when the waterevel is above the central portion of the chamber.
