WILLIAM DOUGHERTY, OF CHESTER, PENNSYLVANIA, ASSIGNOR OF ONE- THIRD TO OARLETON Y. JAMES. OF CHESTER, PENNSYLVANIA.
UPRIGHT WATER-TUBE BOILER.
Specification of Letters Patent.
Patented Sept. 4, 1906.
Application led January 12,1906- Serial No. 295,803.
To I/Z 2071/0711, it 71mg/ concern,.-
Be it known that I, IVILLIAM DOUGHERTY, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Upright Iater- Tube Boilers, of which the following is a specification.
My invention relates to upright watertube boilers, and has for its object the production of a steam-generator of the type stated having special and particular construction and arrangement of parts whereby economy in the consumption of fuel is believed to be attained. I accomplish the object contemplated by fashioning and associating the parts as illustrated in the accompanying drawings, of which- Figure 1 is a vertical section; and Fig. 2, a fragmentary detail view, partly sectional and somewhat enlarged, to show the relative thickness of the regular and brace tubes.
Like numbers refer to like parts throughout.
The casing 1 is usually lined for the greater part of its length udth asbestos sheeting 2 and is' provided with dust-doors 3 of convenient size, structure, and position. The casing connects at the top with a stack 4, having usually a damper 5.
The steam-chamber is marked 6. It has a manhole 7 in the top, and it is my practice to provide other smaller but similarly-situated hand-holes S for the introduction or removal of tubes. The chamber 6 and parts attached below it are partly supported upon the casing by the angle-irons 9, projectingthrough the casing, as shown.
Wvitln'n the steam-chamber 6 and located toward the bottom thereof is the dished diaphragm-plate 10, which is connected with the annular wall-plate 11, touching the bottom of the chamber. Oriiices 12 are provided through the wall 11, and valves 13 are pivotally suspended on the outside of the plate, as shown. The valves will be again mentioned. y
The bottom plate of the steam-chamber 6 is designated by the number 14, and connected with it and extending downwardly are the upright water- tubes 15, 16, and 17. Tubes 15 are the outermost in location and are longer and further distinguished by having portions near their lower extremities curved.
The furnace-doors are marked 21, the
grate-bars 22, and the ash-pit doors 23. The furnace is suitably walled with fire-brick 2-1.
Upwardly-extending ba'liie-plates 25 and 26 direct the products of combustion after passing about the outer tubes 15 toward the inner tubes 16 and 17. Between plates 25 and 26 is placed the middle ba'fIic-plate 27, which directs the gases outwardly. I do not limit myself to the number or position of the baffle-plates. Y
Inspection of Fig. 2 will show that the upper ends of the brace-tubes 17 have threads 28 and that the nuts 29 and 30 engage the threads above and below the bottom 14 of steam-chamber 6. By expanding the upper extremity of the brace-tubes, as shown, the nuts are obviously locked, and it is not possible `for the tubes to give way. Tubes 16 are expanded in the customary way, as illustrated. l
In explaining the operation of my invention, considering Fig. 1, it will be noted that the valves 13 permit the water to pass outwardly from within wall 11, but check its return. The reason for such arrangement is that when the Iire is started in the boiler the bent lower portions of the outer tubes 15 are first heated, and the tendency is to start the circulation up in those tubes. This is contrary to the subsequent and normal circulation and would delay quick steaming were that tendency not checked by valves 13. Very soon the natural draft carries the heated gases about the inner and shorter straight tubes 16 and 17, causing the circulation to start up in them and to return by tubes 15. The valves 13 ofl'er no resistance to this movement, as, being light in structure and under water, their weight is negligible. I have found that the special and particular construction of parts as set forth is peculiarly TOO IOS
5 claim is,-
1. In a water-tube boiler, the combination With the steam-chamber, of a header, the inner straight and shorter tubes, the longer outer tubes having 'curved lower ends connected to 1o the sidewall of the header, and devices con- [structedand arranged to check upward cirlculation in said outer tubes, substantially as 'l described.
2. In a water-tube boiler, the combination 1 5 with the steam-chamber, of a header, the inner straight and shorter tubes, the longer outer tubes having curved lower ends connected to the side wall of the header, and devices located within said steam-Chamb er con- 2o structed and arranged'to check upward circulation in said outer tubes, substantially as described. l
3. In a water-tube boiler, the combination with the steam-chamber, of the header, the inner straight and shorter tubes, and the longer outer tubes having curved lower ends connected tothe side wall of the header, substantially as described.
4. In a water-tube boiler, the combination with the steam-chamber, of a header, the inner straight and shorter tubes, part of the said shorter tubes being constructed heavier than others constituting brace-tubes, means including the locked nuts adapted to secure said brace-tubes to the steam-chamber and header, the longer outer tubes having curved lower ends connected to the side wall. of the header, and devices constructed and arranged to check upward circulation in said outer tubes, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
