v /NyE/VTOR /3 l ATroR/vfx Patented May 13, 1930 PATENT OFFICE HENRY IBAETZ, F ST. LOUIS, MISSOURI AIR HEATER Application led J'uly 5, 1927. Serial No. 203,454.
My invention has relation to improvements in air heaters and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.
r, The principal object of the invention is to provide a radiator for the heater comprising a return bend steam coil from which the water of condensation will drain by gravity when the radiator is either in a. Vert-ical or horizontal position.
Because of this construction enabling the coil or coils to drain by gravity, it is possible to place the same heater in various positions.
The heaters are installed to give the best it is of great advantage if they may be located either at the ceiling, on the floor. or walls,
in either upright or horizontal position without alteration or deficiency in operation. I accomplish these objects by arranging within the casing parallel tubular headers in subjacent planes, between which are connected a series of steam coils. As one header is disposed below the other the coils are inclined, 25, and since the headers are parallel with the casing walls the coils will always be inclined with respect to the casing walls. Hence` it matters not whether the casing be inverted or horizontal so far as the inclination of the coils is concerned. Thus, irrespective of the position of the casing the bank of coils will always drain by gravity.
Another object of the invention is to maintain a blast of air across the coils which is accomplished by disposing a fan. or blower. in one corner of the casing so that the general direction of the air currents is always coextensive with the length of the headers. Other advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which- Figure l is a vertical longitudinal section taken through the heater casing taken on the i5 plane indicated by the line 1-1 in Fig, 2,
results under the conditions encountered, and
the coil bank remaining in elevation; Fig. 2 is a horizontal transverse section teken on the plane indicated by the line 2 2 in Fig. l; Fig. 3 is a side elevation of the lower part of the casing looking toward the fan housing.
Referring to the drawings, C represents a casing having an outlet U at the top and a partition 1 inclined upwardly from the bottom of side wall 2. A pair of headers 3, d, are disposed within the casing on different levels, the header 3 in close proximity and parallel to wall 2 and header 4 in close proximity 'and parallel to wall 5. In the present instance the headers 3, i are tubular in shape and have elbows 6, 7 connect-ed to the lower ce end of header 3 and the upper end of header 4 respectively to receive pipes 8, 9 of a steam supply system. A bank of return bend or serpentine steam coils 10 are connected between headers 3 and 4, the coils lying in parallel planes and being disposed in staggered relation, and alternate coils 10 entering opposite sides of the headers. The header 4 is disposed above the header 3 when the casing C is positioned as shown in Fig. l) and the coil bank inclines downwardly from header 4 to header 3. In other words the plane of each coil intersects a plane at rightangles to the vertical plane in which both headers lie. The straight lengths a of cach coil 10 are spread apart. or diverge sutliciently from bends Z9 so that. considering the inclination oi the coil, each coil will drain by gravity throughout its length from the upper end to the lower end.
The inclination of the coils need be only sufficient to cause them to drain by gravity when the radiator is in either a vertical or horizontal position and the common plane intersecting the headers is vertical. Thus the heater may occupy any one of four posit-ions, i. e., on either side adjacent to a header and either upright or inverted.
Therefore, when the casing is installed in the position shown in the drawings, the pipe @it Q will serve as the steam inlet and the pipe 8 into which all the coils 10 drain, as the steam outlet. Should the heater be installed in an inverted position the inlet and outlet will, ot course, be reversed. Even if the heater is installed with the casing C in a horizontal position all of the coils will drain into the header which is on the bottom. Thus it is apparent that my heater is of practically universal application Without special adaptation.
The partition 1 is provided With a rectangular openingY 16, centrally located with respect to its breadth. and a fan scroll 17 is a banged beneath this openingr in the space between the partition and Wall 5. The sides 18 of the fan scroll extend downwardly rom the lateral margins of opening 1G, thus caving triangular spaces 19, 19 on both sides i the fan scroll. Short angles 20, 20 and i* mounted on either pair of angles 20, 2O 21, 2l. as desired. The motor shaft 25 exvds through one of the fan intake openings z- Q5 in the side Walls 18. 18 of the fan scroll and carries a multi-varied fan 27 for rotation in the scroll 17. rilhus currents of air are forced through the casing and across the steam heated coils 'l0 to the casing outlet O.
Having described my invention, l claim:
1. A steam radiator comprising a bank of juxtaposed return bend pipe coils disposed in parallel inclined planes, adjacent sections oi each coil being spread suiiciently to cause the coil to drain by gravity, each coil having a .steam inlet at its upper end and a steam and water outlet at its lower end, the steam inlets and outlets of each coil respectively being substantially in alinement and the position line of said inlets and outlets being parallel.
2. A steam radiator comprising a banlr ci juxtaposed ret-urn bend pipe coils disposed in parallel inclined planes, adjacent sections of each coil being spread suiiiciently to cause the coil to drain by gravity, each coil having a a5 steam inlet at its upper end and a steam and water outlet at its lower end, the inlets and outlets of the coils lying in a common vertical plane, and the inclination ot the coils being' with respect to a line lying in this plane and at right angles thereto.
3. A. steam radiator comprising; a bank of juxtaposed return bend pipe coils disposed in parallel inclined planes, adjacent sections of each coil being` spread sutticiently to causev the coil to drain by gravity, and each coil havu f 1, Qi are secured in these spaces 19, 19 be- .Ween reinforcing angles 22, 23, and a motor signature.
