STEAIVMGENERATOR.

SPECIFICATION forming part of Letters Patent No. 680,736, dated August 20, 1901. Application filed December 24,1900. Serial No. 40,929. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. RIBLET, a citizen of the United States, residing at Erie, in the county of'Erie and State of Pennsylvania, have invented certain newand useful Improvements in Steam-Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steam-generators and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims.

The invention comprises two leading features: first, the moving of steam or water in a reversed current to that of the heated gases, so as to deliver the hottest steam of which the device is capable, and, secondly, to form a steam-generator in two compartments, one for the water and the other for the steam, and arranging means for subjecting the water to a pressure that will largely prevent steaming in the water compartment and for maintaining the other compartment at a pressure below which the water will steam at the temperature at which it is subjected in the first compartment, so that water passing from the compartment having the greater pressure will immediately be converted into steam. These leading features are also combined and my invention also consists of other features and details, which will hereinafter fully appear in the description and claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure 1 shows a section on the line 1 l in Figs. 2 and 3. Fig. 2 shows a section 011 the line 2 2 in Figs. 1 and 3. Fig. 3 showsasection on the lines 3 3 in Figs. 1 and 2.

The shell A of the generator is preferably made in two sections. It simply incloses the steaming devices and directs and confines the heated gases. Arranged in the upper end of the case is the Water-chamber B. This rests, preferably, on the lugs a in the case. The chamber is provided with the shell I) and the fines b. In fact, this chamber is similar in construction to an ordinary upright boiler. Immediately below the chamber B is a second chamber 0, formed by the shell 0 and having the fines c therein. It is similar in construction to the chamber B and rests upon lugs a, similar to the lugs a If desired, the number of these chambers may beincreased. Connected with the upper chamber is a feed- Water pipe E, and connecting the upper part of the chamber B to the lower part of the chamber 0 is a pipe F. The purpose of so connecting the two chambers is to prevent circulation between them. Extending from these upper chambers are the pipes P, which pass to an ordinary safety-valve P. EX- tending from the chamber 0 is an outlet-pipe Gr. The passage through this pipe is controlled by a valve g, the stem g of which extends out through the case A, so that the valve may be operated. The pipe G passes into a manifold 1-1. This manifold is formed in sections, which are clamped together by means of a bolt h extending through the center of the manifold. Connected with each section of the manifold is a pipe I. It preferably has several loops or coils, and they pass into the manifold J, which is formed of a series of sections secured together by a boltj extending through the center of the section. Passing out of the manifold is a steam-pipe K. The burner Q is arranged, preferably, below the manifold J. Any desired burner or ordinary furnace may be used. Extending between the loops or coils are a series of deflectors a for directing the heated gases by the pipes I. It will be noted that the heated gases nearest the fire contact the outgoing portion of the steam-pipe and that the current of the heated gases as it passes through the generator is in a reverse direction to that of the steam passing out of the generator and that the water-chambers, which are in one sense generators, are also reversed in this same order, so that the hotter gases contact the chamber nearer the steam-outlet. By this arrangement the waterin the chamber G is maintained at a higher temperature than that in the chamber B, and the steam as it passes along the coil I is superheated to the highest degree possible by the arrangement of the reverse currents thus described. A pipe L also is connected with the steam-supply, preferably with the generator, and passes to a steam-pump M. This pump comprises the cylinder M and pump-chamber M The pump-chamber has the usual intake-pipe N,

and the pump has the ordinary valve and incident mechanism. The pump is arranged for direct action and the steam-piston is of a sufficientlylarger area than that of the pumpplunger to elfect the difference in pressure desired between that maintained in the steampipes I and the chamber 0.

By the mechanism so arranged the water in the Water-chamber is maintained at a pressure which will largely prevent steaming in the Waterchambers at the temperature at which they are subjected. At the same time the Water in the said chambers is heated to such a point that it will immediately pass into steam on being delivered into the pipes I at the smaller pressure maintained in the said pipes. In this respect this generator is distinguished from that class known as flashboilers in that the steam is generated not so much by immediate contact with the walls of the pipes I as by the difference of pressure maintained in the pipes I and the waterchamber. The steam as it passes through the coils is superheated. Of course an important feature is that there should be a difference of pressure in the chambers O and the coils I and that the water be heated, so as to steam somewhere between those pressures. As the pressure is increased the temperature may be increased.
