J. E. NEALE ET 1. TUBULAR WATER HEATER OR GEYSER Filed March 21, 1939 L v 77117222725 I Z. J aze flames? MMZLNM Q Patented Nov. 21, 1939 Artur orrlca TUBULAR WATER HEATER OR GEYSER John Ernest Neale and Albert Guest, Coventry, England Application March 21, 1939, Serial No. 263,286 In Great Britain June 10, 1938 Claims. 01. 122-355) This invention relates to pipe systems, 'for geysers, of the kind including at least two superposed, substantially horizontal layers of substantially parallel pipes arranged between headers,
5 with approximately the same number of pipes in each layer, our main object being to provide a compact and highly efiicient construction thereof. Y
According to the main feature of the inven tion, the arrangement is such that the water in one of the layers (preferably in the lowest layer,
or in the lower layer, when there are only two,
(in which the water flows in one direction) arev bent out of the common plane of the layer at one end, these bent ends being connected to an 5 inlet header and the opposite ends by a double header to the inlet ends of the other set of pipes in this layer. Instead of the said opposite ends also being bent out of the common plane of the layer, the said inlet ends of the other set of pipes 30 are preferably so bent, as is actually illustrated in the accompanying drawing, in which case the pipes of both sets can be identical.
In the accompanying drawing:
Figure l is a perspective View of half of one 5 construction, according to the invention, with the header members shown detached, the section being on the line II of Figure 2;
Figure 2 is an end elevation thereof; and
Figure 3 is a longitudinal section taken mainly 40 on the line III-III of Figure 1.
In the construction illustrated, there are two parallel, superposed layers l I, 12 of pipes arranged horizontally, the pipes of one layer being staggered (in plan) with reference to those of the 45 adjacent layer, as is indicated in Figure 2. There is a cross pipe or header l3 of larger bore, disposed at one end of the bottom layer l l, to which the water is fed by the inlet I 4, and this header is connected to each alternate pipe of the hot- 5 tom layer. The ends of this set of pipes may be bent downwardly for this purpose, as shown at it, and from an inspection of Figure 2 it will be observed that there are seven such pipes. At the other end of this layer is a cross pipe or double 55 header 16 to the upper part of which is connected the ends I511. of the set of pipes carrying the inlet water. The lower part of this double header is connected to the other set of pipes of the bottom layer, the ends of the'latter pipes being bent downwardly as shown at H. In like manner the .5 remote ends [1a of these latter pipeslof whichthere are eight in the construction illustrated) are connected to the lower portion of another transverse pipe or double header l8 and the upper part thereof is connected to theadjacent ends of the upper layer 12 of pipes. Therernote ends thereof are connected to a cross pipe or header H] of relatively-large section which' in turn is connected to the water outlet 2d.
The direction of the water flow is indicated by 15 arrows, and it will be evident that therate of flow in the upper layer l2 will be approximately only half the rate of flow in the lower layer, as there are fourteen pipes in the upper layer as against seven and eight in the two setsof pipes in the lower layer.
It is particularly desirable that at least the lower layer of pipes should carry radiating fins or the like, such as are indicated at 2!. These may consist of a plurality of transverse strips with holes in them through which the pipes of the lower layer H extend, such strips being soldered to the pipes to assist in making a good connection, with or without flanges or the like extending along the pipes. They serve for spacing the pipes fromone another in addition to the pipes being held at their ends in spaced relation. Furthermore, the strips may bear against the underside of the upper layer of pipes, or, as is illustrated, be pierced to receive theseand thus assist in spacing the pipesof the upper layer above thepipes of the lower layer. A few strips Zia may be mounted on the bent ends I5 and ll of the two sets of pipes in the lower layer H.
In this way we can provide a very compact pipe system for a geyser and one which in practice is economical of the heating medium, which latter is preferably disposed close up to the pipe system so that the latter will be heated by direct contact with the flames.
What we claim as our invention and desire to secure by Letters Patent of the United States is:
