Description
- UNITED STATES PATENT oE roE. FREDERICK B. HIBBAREJoE PHILADELPHIA, PENNsYLVANIA.
I STEAM-BOILER.
Patented Oct. 23, 1906.
. To all whom it may concern.-
Be it known that I, FREDERrcK B. HIR- BARD, a citizen of the United States, and a resident of the city and county of PhiladeL,
phia, State of Pennsylvania, have invented certain new and useful Improvements in Steam-Boilers, of which the following is a specification.
I My invention relates 'to improvements in steam-boilers, the objects of my invention being to eliminate the objectionable crownsheet usually employed in vertical and locomotive boilers and to furnish an internallyfired return-fire tube-boiler the fire-box of which will be surrounded by water, giving a greater and more effective heating-surface in proportion to the size ofthe boiler than has heretofore been the case, which will have the necessary height to secure proper combustion, which will not have any flat surfaces liable to be prematurely burned out, and which will from its cylindrical form throughout stand very high pressures.
My improved boiler is illustrated in the accompanying drawin s, forming part of this specification, in Whic Figure 1 is a vertical central sectional elevation of my improved boiler, and Fig. 2 a section'of Fig. 1 on line A B.
My boiler consists of two partsa vertical part a and a horizontal part b. The front end of the horizontal part b enters the vertical pprt a and, together with a wall 0, of firebric or other suitable material, forms the top of the fire-box d, which is located in the lower part of the vertical member a.
e represents the grate-bars in the lower end of the fire-box, and f is the fire-door.
As will be seen from the drawings, the vertical member woof the boiler is furnished with double walls forming a space g, the lower portion of which is filled with water and the upper portion of which forms a steam-space. The water-space between the walls of the vertical member a of the boiler is connected with the water-space of the horizontal member b. The steam-spaces of the two members are also in communication, and hence the water stands at the same level in both portions of the device and circulates freely from one part to the other.
The heat and products ofcombustion from the fire-chamber d passto the tubes h in the horizontal member I) of the boiler, thence to the box 7' at the rear of this member, thence through tubes 4 to the upper portion is of the vertical member a, and thence to the stack. The gases after passing through the upper tubes i come in contact with the steam-space in the upper end of the vertical member a and serve to superheat the steam in this space before passing to the stack. Steam may be drawn off through a pipe Z, connected with the steam-space of the part a, or from any other suitable and convenient place.
we represents hand-holes through which access may be had to the interior parts of the boiler for purposes of cleaning.
a is a cleaning-door at the lower end of the smoke-chamber 1c.
An inspection of the drawings will show that the top of the fire-chamber d is formed by the inwardly-projecting portion of the part b and the wall 0, these parts taking the place of the usual crown-sheet. Scale, sediment, rust, &c., which ordinarily fall upon the crown-sheet and which are responsible for the contraction and expansion which results in leaks around the tubes, have in my construction no fiat. sheetto fall upon to cause damage of this character. They must be caught by the lower side of the shell I) or must fall to the bottom of the space 9 between the walls of the vertical part a of the boiler. In either case they can easily be removed through conveniently-situated handhole's m.
My boiler is cylindrical throughout, has a very great and effective heating-surface, and is provided with steam and water spaces of capacity to secure the best results in service.
Having thus described my invention, I claim and desire to secure by Letters Patent- 1. In a steam-boiler, in combination, an internally-fired vertical member and a hori zontal member, the latter of which is provided with two sets of flues and one end of which projects into and forms part of the top of the fire-box in the vertical member, and a wall or partition extending from the inwardly-projecting end of said horizontal member from points between said series to the inner sides of said vertical member completing the top of the fire-box and separating the outgoing and incoming fiue's in said horizontal member, the portion of said horizontal member below said partition projecting into said fire-box.
2. In a steam-boiler, a vertical member, a horizontal member entering one side of the verticalmember and projecting therein to a IIO point adjacent the center of the vertical memand constitute a part of the top thereof, said ber, and a partition secured at a point subhorizontal member having two series of lines stantially central of the diameter of said therein, and a wall disposed between said horizontal member and having its edges projecting portions of said horizontal memr 5 5 abutting the inner Wall of the vertical member and said vertical member to complete the per 8111131 ghe portions ofgaid horilzontalbmemtop of the fire-box.
