STEAM-HEATER.

Specification of Letters Patent.

'Patented lVI-ay 8, 1906.

Application filed June 7, 1904. Serial No. 211,500.

To all whom it may concern:

Be it known that I, JOHN D. MoEAoHREN, a subject of the King of England, residing at Galt, in the Province of Ontario and Dominion of Canada, have invented new and useful Improvements in Steam-Heaters, of which the following is a specification.

My invention relates to improvements in headers for heating systems, and particularly to improvements in headers or manifold s for admitting steam, hot water, or other fluids to coils or radiators of heating systems.

The object of the invention is the provision of a heating system made up of sections or heaters which may be grouped together and inclosed in some kind of a fireproof covering, a fan or other propeller being used either to exhaust or force air through said sections, where it is heated and convey the heated air to more or less distant places where it is desirable to use heated air for heating, drying, ventilating, &c., but such sections are also frequently used for cooling air, in which case they are filled with cold water, salt brine, ammonia, &c., and the'cooled air being conveyed by fan or natural draft to the desired points after being passed through the sections.

The invention consists in certain novel features, combinations, and arrangements of parts'and constructions as herein embodied, particularly pointed out in the claim, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a header and an end elevation of the sections of a heater assembled and connected together by this header, parts being broken away to show the interior. Fig. 2 is an end elevation of the header and longitudinal cross-section of such heater-sections as illustrated in Fig. 1.

In the drawings, 1 indicates a header which is a casting of any desired length having the flange 2 at one end, to which the entrance or supply pipe may be secured. Said header is also provided with sleeves, as 3, having screw-threads therein to which are attached or screwed the pipes 4, which connect said header with the heater-sections 5, as clearly illustrated at the central brokenaWay portion of Fig. 1. Each section 5 is rovided with openings 6 and 7, opening 6 Eeing an additional inlet for another kind of fluid. The openings 7, with pipes connected thereto, are for the discharge of condensed steam, return-water, or other fluids which may be used. These openings may also be connected together by a similar header, as 1, so as to discharge through one outlet.

Pipes 8, connected to the top of the sections, are entered into the sections at each side of the-partition 8 and provide communication between the chambers 8 and 8 of the section, as more fully illustrated in my aplication Serial No. 21 1,501, filed of even i' ate erewith. Steam or other heating fluid is admitted to the header 1 by supply-pipes or pipe fastened to the flange 2 at the end of the eader or at any convenient point. The valve 9 is fastened into the header 1. This valve consists of a body 10, a spindle 11, a hand-wheel 12, a screw 13, a disk 14, and a seat 15. There may be as many valves in the head er as there are sections to the heater, or some sections may be supplied with valves, while others have none. As shown in Fig. 1, the header is provided with openings 16, which may be covered with caps, in which openings the valves may be located. The header at the extreme left has no provision for a valve, there being a valve providel in the supply-pipe leading to the header, and when this is open at least one section will be filled with fluid which it conveys, while all the other sections or any number of them may be shut off by means of the valves 9, which should be provided for as many sections as are desirable to use live steam in one or more sections and exhaust in all or part of the others. In such a case as many sections as would be desired for live steam might be connected together by a similar header with inlets at 6, admitting live steam atone or more inlets, as may be desired. The outlets 7 discharge condensed steam or other fluid and may be assembled in a similar manner, discharging the condensed exhaust steam in one direction and condensed live steam in the opposite direction simply by means of opening or closing valves.

IVhile I have described my invention in connection with a heating system, itwill be understood that I contemplate using the system for cooling air, as before mentioned, by cold water, salt-brine, ammonia, &c.

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

The combination of a plurality of rectangular base-sections with a header located above said sections, vertical pipes supporting the header and forming communication between said header and sections, a plurality In testimony whereof I afiix my signature of pipes conveying fluids to one point of disin the presence of two Witnesses.
