Description
@sind @Wina ISAAC N. WILFONG, PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 91,294, dated June 15, 1869.
IMPROVEMENT VIll-N STEAM-GENERATQRS.
Tbechedule referred t in these Letters Patent and making part of the same.
Be it known that I, ISAAC N. WILnoNG, of Philadelphia, in the `county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to theannexed drawings, making apart of this specification, in which- Figurel isa vertical transverse section of the improved boiler;
Figure `2, a longitudinal section; and
Figure 3, a sectional plan.
Figures 4 and '5 show the connection between the feed-water heater and boiler, and
Figures 6 and 7 different ways of bending the tubes.
The improved steam-boiler consistsof two parallel cylinders, a and a', connected by curved tubes b b b b and c c c e, in addition to the straight tubes d d, which are usually used for .this purpose.
The curves of these tubes are such that their ends will enter the shell of thc cylinders 'c and a at or nearly lat right angles with a tangent line Adrawn through'the point of junction with the cylinder, as shown at w, iig. 6.
The tubes are set in rows transversely across the boiler, and may be bent in different ways, as shown 'y at x, in figs". 2, 6, and -7 but 'it is preferable'to bend them, as shown in iig. 1, Where b b b b start at the left of the lowerlcylinder, cross over to the right, and there enter the upper cylinder. ,c c c c take a contrary direction.
Nearly on a level with the centre of-a.' are partitions e and e, for the purpose of interceptiug the heat, and to cause it to pass over the top cylinder a into the ues f and f', through the passages gand' g', which are formed bythe annular partitions It vh h around the upper half of a. y l
i In Iig. 3 is shown how the passages g` and g' alternate, g communicating with `the right side of the furnace andthe left iiue f', and g' connecting the left side of the furnace Withthe right flue f.
The products of combustion pass iiom the` fines f and f into the smoke-chamber It, and from thence through the chimney l, but here they meet with. the
feedwater heater m, which maybe a vessel of either tubular, iiue, or other well-.known construction, connected, by suitable means, with the pump of the engine, and also with the boiler, in such a manner that the feed-water has to pass-through it before .entering the boiler. v
By referring to figs. 4 and 5, it will be observed that the feed-pipe r is also used as a blow-off pipe, by means of the three-way cock and branch s.
, Fig. 4 shows the cock in position for blowing o", and iig. 5 for feeding.
The feed-pipe o, fig. 2, passes to the bottomv of the boiler, and terminates there in an open funnel, p.
The advantages of the curved tubes are, that less injury results from their expansion, greater length, and consequently more heatingsurface are obtained, and their being exposed to more heat than the straight tubes d d, causes the Water to circulate rapidly.
- By the passages and partitions across the top cylinder, and by the feed-water heater, a large amount of heat is saved, and by using the feed-pipe at the same gime as a blow-olii` pipe, the cost of construction is reuced. i
I do not limit myself to the number of' tubes in one row, nor to the number of' rows in a boiler. For marine purposes, a hollow metal case, to hold Water, may be substituted for the brick-work.
I do not claim as my invention the connection of the cylinders a and e', by means'of straight tubes, nor the idea of placing a feed-Water heater in the chimney of a boiler; but
What I claim as my invention, is-
1. The arrangement of a series of curvilinear tubes, connecting to parallel cylinder boilers, substantially as described.
2. The passages g g', formed bythe partitions h h h, substantially as set forth.
3. The combination of the partitions h. hh, passages g g', andv iiues fand f', with the cylindrical boilers a and et', substantially as specified.
4. '.lhe arrangement ot' the heater m, pipe fr, threeway cock n, branch s, and boilers a and a', substantially as specified.
