CONSTRUCTION OF WATER-TUBE BOILERS.
Specification of Letters Patent. Patented Mar. 16, 1915.
I Application med July 20, 1914. Serial No. 852,077.
.To all whom it may concern:
Be it known that I, Ronnn'rDELAUNAx- BELLEVILLE, citizen of the French Republic, residing at St,-Den.is, Department of the Seine, in France, have invented certain new and useful Im rovements in the Construction of Water-Tube Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. In a multiple coil Belleville boiler element, in which the coils are so arranged that their convolutions are co-axial and each convolution of each coil lies vertically ad acent to a convolution of another coil, it is important to equalize, as far as possible, the vaporization of the several .coils. The pres cnt invention aims to provide a boiler eles ment so constructed that the above result may be obtained. The 'invention consists in shortening the lower convolution of the first two coils of the element, so as to uncover or expose a portion of the lower convolution of the second coil and of the third coil, and consequently, increase I the vaporization power of these tubes.
It is important, in order to economize space, to arrange the junction boxes above the lowermost tubes in superposed and horizontal relation, as in a s ngle coil element, with the exception of the lower reap boxes 'of the first and second coils, which are;
formed as hereinafter describe The invention is illustrated in the accompanying drawing, in which:
Figurel shows the improved boiler element in sideelevation; Fig. 2 is a front elevation of the element showing the lower front odx, oartly in section, and showing the other front junction boxes superposed in horizontal relation; F i .3 is a rear elevation showing the 'rear oxes'superposed in horizontal relation from the lower box of .the third coil to the top, the lower rear box "box is 0 hate the rear boxes. The letters V and R arefurnished with indices, which indicate the tier of the boxes reading upwardly.
AV, BV, CV are the three compartments of the lower front box common to the three coils. T he water comes from the feed llector D through a conduit of large cross section d, fills the chamber E, and passes through. the adjusted orifices 1, 2, 3, into the compartments AV, BV, and CV from which the lower tubes of the three coils proceed. The other boxes are superposed in horizontal relation like the boxes of a single coil element. The upper box F also comprises three compartments having independent communication with the upper collector.
In each coil, the tubes are designated by a small letter with an index .which indicates the tier, starting with the lower tube, which is numberedyl. The tubes of uneven number rise froui front to rear; they are shown on the right hand in Fig. 2. The tubes of even number ascend from rear to front; they are on the left of Fig. 2.
At the rear, the support for the boxes is carried to the under side of the box OR. The boxes AR,'BR need no support. All the other rear boxes GR, AR, BR, CR
are superposed in horizontal relation, as in an element with a single coil.
The first convolution of the coil A is constituted by the tubes (1 and a, which are relativelg short and by the box AR, This (Fig. 3), to permit of the passage of the tube 12 of the second coil.
The first convolution of the second coil is constituted by the tubes 12, 12*, which are relatively short, but longer than the t bes (1, a of the first convolution. The box 53: connects the tubes 5 b and com lets: the convolution. This box is also 0 set from set horizontally from right to left,
right to left to permit of the passage of the In each coil, the circuit is formed from below upv- 1rd, from box to tube and from tube to box in the following order, taking the coil C for example; (JV -c,-CR c CV CR -c- CV c- CR, and the corresponding compartment of the upper box F. All the tubes inclined in" the same direction are substantially parallel,
Fig. represents a modification. in which the rear boxes of the first convolution of the first and second coils are dispensed with.
The tubes 11 and (1 for the first coil, comprise but a single tube a, a. The same applies to the tubes 6 and b of the second coil. In each of the firsttwo coils, this tube, which itself forms the first convolution, is deflected or ofi'set from right to left in order not to interfere with the passage of the first tube ofthe coil which is located above; it then ascends and is connected with the box AV of the first coil, or BV of the second coil.
What I claim is 1. A boiler element composed of a plurality of coils having co-axial convolutions, each convolution of each coil being vertically adjacent to a convolution of another coil and the lower convolution of certain coils being shorter than the lower convolution of the adjacent coil, for the purpose described.
2. A boiler clement composed of three coils each having a plurality of convolutions arranged in co-axial relation, each convolution of each coil being vertically adjacent to a convolution of another coil and the lower convolution of the second coil being shorter than the lower convolution of the third coil, and the lower convolution of the first coil being shorter than the lower convolution of the second coil, for the purpose described.
In testimony whereof I ailix my signature, in presence of two witnesses.
