JOSEPH WILLARD GAMBLE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOB, TO JOSEPH S. LOVERING 'WI-IARTON, 'VVILLIAM S. I-IALLOWELL, AND JOHN C. JONES, DOING BUSINESS UNDER THE FIRM-NAME OF HARRISON SAFETY BOILER WORKS, OF

PHILADELPHIA, PENNSYLVANIA.

FEED-WATER HEATER AND SEPARATOR.

To all whom it may concern:

Be it known that I, Josnrn ILLARD GAM- BLE, a citizen of the United States, and resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Feed- VVater Heaters and Separators, of which the following, taken in connection with the accompanying drawings, a concise and complete description thereof.

The invention particularly relates to certain improvements in afeed water heater construction, described and claimed in Patent No. 926,108, granted to me June 28th, 1909.

Among the objects of my invention, is to provide a complete and simple device, eflicient and economical in operation, and especially to provide therein improved means for cutting the separator out of communication with the heater and overflow chamber, in order to afford the opportunity of cleaning the heater with perfect safety, free from any liability of the water or steam within the water sealed overflow chamber being forced back into the heater, which is the case when the separator chamber is in 'open comn'iunication with the overflow chamber by a drip connection, througl'i which, (in the event that the inlet to the heater is closed) the pressure of steam within the separator is communicated to and exerted upon the water or steam in the overflow chamber, thus forcing the same back into the heater. For the accomplishment of this object, as well as others, I have provided, as illustrated in the accompanying drawings, and described in the following specification, a structure that I may employ in carrying out my invention. 1 would have it understood, however, that I am not limited to the particular device which I have illustrated as the one by which I accomplish my objects, since other equivalent means may be employed, without departing from the scope and tenor of my claims.

Referring to the accompanying sheet of drawing, 1 indicates a portion of the wall or shell of a heater.

2 indicates the separator.

3 indicates the overflow chamber from the heater, and Z outlet from overflow chamber to waste.

The heater is provided with an exhaust in- Specification of Letters ratent.

Application filed January 18, 1910.

Patented Dec. 27, 1910.

Serial No. 538,733.

let opening l from the separator 2 and an overflow outlet 5- leading to the overflow chamber 3-. \Vithin the separator 2 is provided a ribbed bafi'le 6-, indicated by dotted lines. The separator also is provided with an auxiliary outlet leading to a heating system or other point of use (not shown).

-8 indicates the separator drain or drip connection provided with two outlet connections 8 and 8-, connection -8*- discharging into the water sealed leg of the overflow chamber -3 at S, and the connect-ion 8 discharging directly to waste exterior of said overflow chamber.

9 indicates a skimmer within the heater, down through which the overflow water is passed to waste, this being of usual and well known construction.

The exhaust inlet 4land the separator drip outlet -8 are controlled by valves 10 and -11-, which are connected through intermediate mechanism, and operate simultaneously, the valve --10- to control the admission of the exhaust steam to the heater 1 from the separator 2- and the valve 11- to control and divert through one or the other outlets -8- and 8", as the case may be, the entrained impurities of such exhaust steam as may be separated therefrom in passing through the separator -2-. The manner in which these valves are constructed, mounted, and operated, is substantially in accordance with the following detailed description:

Rotatably mounted outside of the heater proper is a shaft -12 upon which is keyed, or otherwise suitably mounted, a valve 10.

12 indicates a lever or handle fast upon shaft -l2-, for the purpose of operating the valves. The valve casing -1lcontaining the valve ll as explained, is arranged intermediate the drip connection 8 and its branched outlets 8- and --8". The valve -11- is connected to the valve 10 and operates simultaneously therewith through the operation of the lever -12. The valve casing 11- is constructed with two interior openings 11"-- and 11 governed by disk valve 1l, all of which is suitably indicated by dotted lines. The opening, 11 communicates with pipe -8 leading into the lower portion of the overflow chamber, and opening 11" communicates with the pipe 8" leading directly to waste. It is apparent, however, that the pipe 8"- may be reversed upon itself, so as to form a water seal, and then discharge into an opening in the overflow chamber 3- provided therefor.

The mechanism for operating the valve -llmay be described as follows: A valve rod --l3 at the end of which is fastened the valve 1l is slidably arranged within the valve casing 11-, the same being provided with a suitable packing, to prevent leakage, etc. A supporting link l4 fastened to the valve casing has pivoted thereto a draw lever -15 which, in turn, has connected therewith rod l3- carrying the valve ll" as shown. Pivoted at one end of extremity of the lever 15- is a connecting rod 16- which is connected to an arm -17- mounted or keyed upon the shaft 12. From this description, it will be apparent that when the operating arm -12 is actuated to open the exhaust valve l() to admit the exhaust steam from the separator to the heater, the valve ll in the drip connection will be raised through the operation of the connecting linkage, so as to close opening -11 and uncover the opening -11 of the valve casing l1, thus directing and discharging the separated matter received from the separator into the water seal of overflow chamber Now, on the other hand, when the exhaust inlet valve -10 is closed, in the position shown) the valve 11- will be in its lower position, closing opening 11% and diverting the separated matter tirough opening -11 and discharging it directly to waste through pipe 8 In the latter position, there exists no communication between the separator and the heater, thus eliminating any liability of the water in the overflow chamber 3- being forced back into the heater through outletopening 5 by the steam pressure created within the separator 2 communicating through the drip connection S, and also the steam itself, both of which would prevent cleaning the heater with safety. It will also be apparent from my arrangement as described, that at all times the overflow from the heater will be free and unobstructed, whether the exhaust inlet valve be in open or closed position.

The operation of the heater is as follows: The exhaust steam enters the separator -2- in the direction of arrow A. and i1npinges on the baflle 6, (which is of well known cor ated type) where the solids and impurities are arrested and separated from the steam, the steam then passes around the battle through suitable openings at its evaaea sides. Now supposing that the valves are in the reverse position, to that shown, the ports kand 11 being uncovered, the purified steam passes through the port l: into the heater, Where it contacts with the raw water, which, upon being admitted to the heater, is disintegrated and broken. into small particles in the well known manner. The water, after abstracting the thermal units from the steam, and having its temperature thereby raised, is drawn off through a port, (not shown) for any required service. Normally the service demand for the heated water does not exceed the rate. of supply at which the water is admitted to the heater, but itmay sometimes happen, through derangement of the working parts, such, for instance, as if the valve controlling the raw water supply becomes inoperative, or in case of obstruction of an interior filter (when one is used) then the water level within the heater will be raised until it reaches the top of the skimmer 9, in which event the surplus will then pass down through the overflow outlet -5- into overflow cham ber -3, and thence through outlet 3 The entrained and separated matter from the separator flows down through drip connection 8 through passage l1" down through leg 8 into the water seal compartment of the overflow chamber 3, and thence through the outlet 3"-. Now, when it is desired to interruptthe flow of exhaust steam from the separator to the heater, to give the latter part time service, the operating lever 12 is given a partial rotary movement upward until the valves -l0 and 11 are closed through the operation of the intermediate connecting mechanism described. In this position, the exhaust steam passes out through the auxiliary outlet, (not shown,) in the direction of the arrow B, to a heating system or other point of use (not shown). The exhaust steam, whichever way it flows, impinges the bafiie 6, and is purified within the separator, and at all times when the separator is operating, entrained substances aeoumulate and should be taken care of by being passed off to waste. Therefore, in this latter position, as shown in drawing, the entrained matter leaving the separator -2- through drip connection 8 is caused to flow through opening 11" of the valve casing 11, and passes out through leg S where it is discharged directly into an exterior waste, or, as mentioned above, may be, by reversing the pipe upon itself to form its own water seal, dis charged directly into the overflow chamber 3 through a suitable opening therein provided for the purpose.

Where I have used the term overflow chamber, I mean any overflow into and through which may be discharged the separated waste products of the separator or surplus water from the heater, or both; and as a special type of overflow chamber, I would mention the well known form of steam trap.

\Vhere I have used the words combined heater and separator, I mean that both the heater and separator form part of the same structural unit.

here I have used the words unitary structure I mean that the component parts, such, for instance, as the heater, separator and overflow, form part of the same structural unit, though they are not necessarily integral.

Having thus described my invention, what I claim and desire to protect by Letters Patent, is:
