UNITED STATES PATENT OFFICE.,
JOHN NICHOLSON, OF ALLEGHENY CITY, PENNSYLVANIA.
IMPROVEMENT IN FEED-WATER HEATERS.
Specicationforniing part of Letters Patent No. 69,576, dated October 8, 1867.
To all whom, it may concern,.-
Beit known that I, J OHN NICHOLSON, of the city and county of Allegheny, in the State of Pennsylvania, have invented a new and useful Improvement in Heaters for Heating Water for Steam-Boilers, the samev being an improvement of the heater for which I did obtain Letters Patent ofthe United States, bearing date constructed and arranged with relation to the. injector and boiler that the steam which operates the injector passes through the heater to the injector, and heatsthe water in its passage from the injector to the boiler.
To enable Othersskilled in the art to make anduse my invention, I will proceed to describe its constructionand operation.
In the accompanying drawing, which forms part of my specification, A represents a strong metal case, which is made in two parts,which V are secured together' by the flanges marked l and 2. 'Ihe case A is provided with` pipes or branches G and D and caps e. The steamchamberB is placed inside of the case A, and` is so arranged with relation to the case A as to leave a very narrow space (marked i) between the outside of the steam-chamber B and the inside of the case A. The steam-chamber is provided Awith pipes f and f', which passl through the caps e of the case A.
Y As the construction and arrangement of my improved heater will be readily understood by the skillful mechanic by reference to the accompanying drawing, I will therefore proceed to describe its application and operation, which are as follows: The pipe C of 'the case A is attached to the injector, and the pipe D is connected to the steamboiler, and the pipe f of the steam-chamber B is attached to the injector, and the pipe f is connected to the steam-boiler. Having the pipes O, D, f, and f properly connected to the boiler and injector, and suitably' provided with valves, steam is let into the chamber B, from which it passes to the injector for operating it. The water passes `from the injector through the pipe C into the space t', and down this narrow spacer' into the pipe D, and through it into the boiler. The water is heated in its passage down through the narrow space marked fi. The arrows marked 3 indicate the course of the water from the injector through the heater to the boiler, and the arrows marked 4 indicate the course of the steam from the steamboiler through the heater to the injector.
It will be observed that the water is heated after it leaves the injector, and that it is heat ed by the steam which passes through the steam-chamber B, and that the steam which passes from the steam-boiler through thesteamchamber B operates the injector.
The advantage of my improvement consists in supplying heated water to the steam-boiler and obtaining an even, steady, and uniform action of the injector, all of which result from a combination of the action of the ordinary injector with theaction of my improved water-heater.
Having thus described the nature, construction, application, operation, and advantages f of my improvement, what I claim as of my invention is- A water-heater for steam-boilers,when constructed,arranged, and operating substan.
tially in the manner herein described, and for the purpose set forth.
. JOHN NICHOLSON.
