JOSEPH WILLARD GAMBLE AND AXEL BLYTT WALLEM, OF PHILADELPHIA, PENN- SYLVANIA, ASSIGNORS T0 JOSEPH S. LOVERING WHARTON, WILLIAM S. HALLO- WELL, AND JOHN C. JONES, DOING BUSINESS UNDER THE FIRM-NAME 0F HARRISON SAFETY BOILER WORKS, OF PHILADELPHIA, PENNSYLVANIA.

HEATER AND SEPARATOR.

To all whom it may concern:

.Be it known that we, JOSEPH WILLARD GAMBLE and AXEL BLYTT WALLEM, citizens of the United States, and residents of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Heaters and Separators, of which the following, taken in connection with the accompanying drawings, is a concise and complete description thereof.

This invention particularly relates to certain improvements in a construction described and claimed in a co-pending application, serially numbered 431,271, filed May 6th, 1908.

The chief object of our present invention is to provide improved means for cutting out of communication with the heater, the separator and overflow chambers thereof, in order that one may be afforded the opportunity of cleaning the heater with perfect safety, free from any liability of the Water or steam within the overflow chamber being forced back into the heater, which is the case when the separator chamber is in direct communication with the overflow chamber by a drip connection, through which, (in the event that the inlet to the heater is closed) the pressure of steam within the separator is communicated and exerted upon the water or steam in the overflow, thus forcing the same back into the heater.

A further object of our invention is to render it impossible to cut off or interrupt the overflow from the heater when the same is in operation.

To the accomplishment of these, as well as other objects, we have illustrated in the accompanying drawings, and described in the following specification, a structure that we may employ in carrying out our invention. We would have it understood, however, that we are not limited in respect to the manner in which we accomplish our objects, since other equivalent means may be employed without departing from the scope and tenor of our claims.

Referring to the annexed drawings, in which like reference numerals indicate like parts throughout the respective views; Figure 1 represents so much of a combined heater and separator, partly in section, as is Specification of Letters Patent.

Application filed April 21, 1909.

Patented June 27, 1911. Serial No. 491,285.

necessary to illustrate one form of our pressent lnvention, 1n whlch mechanlsm is em ployed for successively or simultaneously Referring to Fig. 1 of the drawings in de tail, 1- lndicates a portion of the wall or shell of a heater.

2 indicates the separator, and -3 indicates the overflow or outlet to Waste. The heater is provided with an exhaust inlet opening, 4, leading from the separator 2, and an overflow outlet 5leading to the overflow chamber 8. Within the separator -2- is provided a baflle 6, indicated by dotted lines. The separator is also provided with an auxiliary outlet 7 leading to a heating system or other point of use (not shown).

7 indicates a deflecting plate connected to the battle.

8 indicates the separator drain or drip connection to the overflow or outlet chamber 3 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.

Both the exhaust inlet 4 and the overflow outlet -5 are controlled by rotary valves 10 and 11' respectively. These rotary valves are connected through intermediate mechanism, and operate successively or simultaneously. The manner in which these valves are constructed, mounted, and operated, is substantially in accordance with the following detailed description: Rotatively mounted outside the heater proper, is a spindle 12 upon which is keyed, or otherwise suitably connected, a collar retaining member --13 carrying a screw threaded shaft 14- which is connected to and operates the valve 10.

15 indicates a packing box through which the spindle 12 is journaled.

-16 is a spring, interposed between the valve 10 and the projecting flange on the collar retaining member 13 for an obvious purpose.

Fastened to the shaft 12 is an arm 17- having at its outer end a projecting pin or stud -l8-.

19 indicates a spindle mounted in the casing of the overflow chamber 3-. To this spindle is suitably fastened the rotary valve 11- cont-rolling the overflow port or outlet 5.

20 indicates an arm or crank keyed to the spindle 19-.

-2lindicates a link pivoted to the arm 20 at one end and connected through slot connection 22-- at its other end to the projecting pin or stud l8 of the arm 17.

23 indicates an operating lever suitably fastened upon the spindle -19.

2l indicates a gulde plate provided with suitable stops for limiting the movement of the operating lever.

Supposing both exhaust inlet and overflow valves are open, the exhaust steam will enter the separator in the direction indicated by the arrow A, impinging and passing around baffle plate 6 and through inlet -4 into the heater, where it contacts with and heats the water admitted thereto by any suitable supply. The overflow from heater passes down through passageway 9- through exit opening -5 into overflow chamber 3. WVhen the valves are closed, as shown, the exhaust steam, after contacting with the baffle -6 is passed directly up through auxiliary outlet -7 and indicated by arrow B to another point of use. The entrained oil, water, or other separated matter which has been separated from the exhaust steam within the separator, is led to the overflow chamber through drip connection 8. hen the heater has been cut out by reason of both valves being closed, it will be readily seen that any pressure that may be created within the separator and acting through the drip connection upon the water in the overflow chamber, cannot force it back into the heater, hence the cleaning operation of the heater can be accomplished without interference. It will be further apparent from this description that when the exhaust inlet valve to the heater is open, and the overflow valve is open, there is secured a free overflow passage at all times when the heater is in operation.

The detailed operation of the valves and operating mechanism, is as follows, reference being had to Figs. 1 and 2 of the draw" ing:It will be noted that three positions of the valves and mechanism are shown in closed position, (Fig. 1) and partial and full opening of the pilot valve 1.1 before the exhaust inlet valve 10 begins to open (Fig. 2). hen the lever 23 is operated to open the valves, the arm 20 being keyed and fast to shaft 19- will rotate therewith. This will cause the link 21 having the slot connection with the arm -17- (which allows a suflicientamount of lost motion to operate the valves in the manner desired,) to vertically move, until it becomes substantially perpendicular as shown in full in Fig. 2. In this position, the pressure of the exhaust steam is permitted to enter ino the heater through passageway 5 and there exert an equal pressure against the inner face of the valve l0 to that exerted on the separator side of said valve, and thus facilitate and ease the operation of the exhaust inlet valve 10. Upon further operation or rotation of the operating lever 28, further lost motion is permitted by reason of the slot connection of parts 17 and 21, until the upper end of the slot -22- engages the pin or stud 18. In this position, the pilot valve 11 is almost completely opened, while the exhaust inlet valve still remains closed. Now upon further operation or rotation of the operating lever, the exhaust steam inlet valve 10- will operate to open the inlet. Thus, we accomplish the opening of the two valves successively in a manner that minimizes the amount of requisite force or power. It will be further noticed that when the valves are in a closed posit-ion that the pilot valve is locked by reason of the parts -20 and 2l having passed their common alined position, (as shown in dotted lines in Fig. 2,) so that the weight of the parts will tend to hold the pilot valve 11 in closed position by reason of gravity.

We do not wish to be understood to be restricting ourselves to the successive operation of these valves; but on the contrary, we may, if we so desire, operate the two valves simultaneously.

Where we have used the term overflow chamber we 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, we would mention the well known form of steam trap.

It will be understood that we do not wish to be restricted to the specific several embodiments of our invention. e may depart therefrom without departing from the spirit and scope of our invention.

here we have used the words combined heater and separator, we mean that both the heater and separator form part of the same structural unit. here we have used the words unitary structure, we mean that the component parts, such, for instance, as the heater and separator and overflow, form part. of the same structural unit.

While we have illustrated and described our invention as applied to a feed water heater, we would have it distinctly understood that we are not limited to this specific embodiment, as it is manifest that a rewithout departing from the scope and tenor of our appended claims.
