HEATING SYSTEM FOR ENGINES.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed March 7, 1914. Serial No. 822,146.

To all whom it may concern:

Be it known that I, JOHN A. SoMMnns, citizen of the United States, residing at Plentywood, in the county of Sheridan and State of Montana, have invented certain new and useful Improvements in Heating Systems for Engines, of which the following is a specification.

This invention relates to feed water heaters for traction engine boilers and it has for its object the provision of an improved device of this character adapted to be located in the smoke box of the boiler and to heat the feed water by utilizing the otherwise waste products of combustion before they pass through the stack.

A further object of the invention is to provide a mud drum also located in the smoke box where it will be acted upon by the heated products of combustion, said mud drum and the heating element for the feed water being so located that they will not interfere with the proper cleaning of the boiler tubes.

Further objects and advantages of the invention will be set forth in the detailed description which now follows:

In the accompanying drawing Figure 1 is a side elevation of a traction engine boiler having the improved water heater applied thereto, Fig. 2 is a partial longitudinal sectional view through said boiler, and Fig. 3 is a transverse sectional view upon line 33 of Fig. 2 looking in the direction indicated by the arrow.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing the numeral 5 designates a traction engine boiler having the usual fire tubes 6. These tubes terminate short of the front end of the boiler shell 7 so that a smoke box 8 is provided in the usual and well known manner. this smoke box and above the lineof the fire tubes, is a coil 9. A pipe 10 leads from this coil to the feed pump 11 and this feed pump is supplied through pipe'l2 froma water tank 13 located at the rear of the boiler. A check valve 1 1 and cut off valve 15 are provided in the pipe 10 and pipe 16, the

latter pipe leading from a mud drum 17 located within the smoke box and conforming closely to the shape of the wall of said smoke box, see Fig. 3. Pipe 16 leads from the upper portion of the mud drum and the coil is likewise connected with the upper Located in portion of the mud drum'at 18 by virtue of which construction any mud or other sediment in the water will, when it sinks to the bottom of the mud drum, be out of the line of the travel of the water between pipes 18 and 16. from the bottom of the mud drum and is provided with a drain valve 20. The water is drawn from tank 13 through pipe 12 by.

pump 11, and is discharged from pump 11 through 10 and coil 9 to the mud drum 17. It passes from the mud drum through the pipe 16 and enters the boiler at 21. It is apparent therefore that during this passage of the water through the coil 9 and mud drum 1?, the water will be heated during its travel through the coil and mud drum, since the coil and mud drum are disposed within the path of the products of combustion from tubes 6 to the stack 22.

I am aware of the fact that it has been proposed heretofore to heat the feed water by carrying said feed water through a coil or other heating element disposed within the path of the products of combustion and even carrying the water through a coil disposed within a smoke box, but I am not aware of the fact that it has ever been proposed to carry the feed water through a coil so located with relation to the fire tubes that the cleaning of said tubes is not interfered with nor am I aware of the fact that any mud drum has ever been employed located in the smoke box and conforming to the shape of the side walls thereof so that the cleaning of the tubes is not interfered with while at the same time the mud drum is utilized as an additional heating element.

From the foregoing description it will be seen that simple and efficient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my'invention, what I claim is:

1. A feed water heater for boilers comprising a spiral elliptical coil located in the smoke box of the boiler and entirely above the line of the fire tubes thereof, but entirely below the entrance to the smoke stack,

A drain pipe 19 leads V each succeeding lower coil being otgreater length than the one thereabove so that the coil is caused to completely fill the smoke box above the line of the tubesand connections between said coil and a source of Water supply and between said coil and the boiler.

2. A feed Water heater for boilers comprising a spiral elliptical coil located in the smoke box of the boiler and entirely above the line of the fire tubes thereof, each succeeding lower coil being of greater length than the one thereabove so that the coil is caused to completely fill the smoke box above the line of the tubes, connections between said 0011 and a source of Water supply and betweensaid coil and the boiler, and

a mud drum supported at one side and inside ofthe smoke box but out of the line of the fire tubes and to which said coil is connected.

ln'testiniony whereof I aflix my signature Copies of this'p'atent may be obtained for fivecents each, byaddressing the Commissioner of Patents, 'Wa'shington, 11:0.
