JAMES T. SMITH, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO MITCHELL K. GATHELL AND ROBERT V. OATHELL, OF BALTIMORE,
MARYLAND SPECIFICATION forming part of Letters Patent No. 717,636, dated January- 6, 1903.
Application fi1ed February 16,1902. seen No. 94,247. on model.)
To all whom it may concern:
Be it known that I, JAMES T. SMITH, of the city of Baltimore, State of Maryland, have invented certain Improvements in Water-Tube Boilers, of which the following is a specification. In the description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which- Figure 1 is a half central front section of the improved Water-tube boiler, and Fig. 2 a half central side section of the same. Fig. 3 is a top view of the tube-sheet of the boiler.
Referring now to the drawings, 1 is the cylindrical outer shell of the boiler, having the head 2.
3 is the inner shell, crowned by the tubesheet 4 and forming with the outer shell 1 the annular water-space 5. The inner shell is strengthened in the usual manner by staybolts, some of which are shown and denoted by 7.
The grate-bars are represented by 9, and the bearing-bars which sustain them by 10, and the furnace and ash-pit doors are respectively denoted by 12 and 13.
14 is the uptake, extending from the tubesheet 4. to and through the head 2 of the boiler.
15 is a cylindrical heater extending transversely of the space Within the inner shell 3 and situated at an appropriate height above the grate-bars. This heater opens into or is in communication with the annular waterspace 5, as shown in Fig. 1.
17 17 are water-tubes grouped around the uptake and extending from the water-heater 15 to the tube-sheet 4. In Fig. 1, which shows the front of the boiler, the water-tubes are shown as extending vertically from the heater, and in Fig. 2 they branch from the same, the lowest tubes extending the farthest in a lat eral direction. The ends of the water-tubes are expanded in the tube-sheet and the heater in the usual manner, and in order to give access to their lower ends for this purpose the outer shell of the boiler is provided with manholes 19 in alinement withthe heater,as shown in Fig. 1.
Referring now to Fig. 3, it will be seen that the arrangement of the water-tubes is such that alleys or spaces of increased width are formed between certain of the tubes, which alleys admit of any tube being removed without the removal of others. This is an important feature of the invention, as in many boilers it is necessary in order to remove a leaking tube to take out one or more tight ones.
pact volume directly to the uptake, but instead to cause them to takea circuitous passage, and thereby bring them in contact with the upper portion of the water-tubes, and so increase the efiectiveness of the boiler as a water-evaporator.
The tube-sheet is braced in the usual manner, and one brace (denoted by 25) is shown in Fig. 2.
' I claim as my invention- 1. In a vertical, cylindrical water tube boiler, the combination with an outerand an inner shell, of a water-heater which extends transversely of the space within the inner shell and opens into the annular water-space between the two shells, and a system of water-tubes which place in communication the said heater and the space above the tubesheet, and which tubes at their upper ends are vertical, and at their lower ends converge toward the center of the water-heater, substantially as specified.
2. In a vertical, cylindrical water tube boiler, the combination with an outer and an inner shell, of a Water-heater which-extends transversely of the space within the said inner shell and opens into the annular water-space between the two shells, and a system of watertubes which place in communication the said heater and the space above'the tube-sheet,
and aperforated cylindrical heat-deflector dependent'from the tube-sheet, around which the said tubes are grouped, substantially as specified.
JAMES T. SMITH.
