DOOR AND DEFLECTOR-PLATE FOR STEAM-BOILER FURNACES.
SPECIFICATION forming part of Letters Patent No. 626,280, dated J une 6, 1899.
Application tiled July 2l, 1898.
T0 @ZZ whom t may concern:
Be it known that we, FRANCIS L. IIORSPOOL and Geenen J. KELLY, citizens of the United States, residing at Ogden, in the county of Veber and State of Utah, have invented a new and useful Door and DefiectorPlate for Steam-Boiler Furnaces, of which the following is a specification.
This invention relates generally to doors for steam-boiler furnaces, and more particularly to certain improvements therein embodying the application of deflector-plates in conjunction with the` doors.
The object of this invention is to provide a furnace-door which will save time and labor in firing the furnace and will admit the necessary amount of air above the tire in the firebox to supply sufficient oxygen to complete the combustion of the carbon of the fuel, thereby economizing in the consumption of the fuel.
With this object in view our invention consists in a steam-boiler furnace provided with a door made in sections capable of independent operation and the lower section hinged at its side to the frame and provided with a deflector or guard plate permanently secured to the inside thereof, whereby accumulation of cinder or ashes against the door is prevented, and an improved defleotor being projected from the doorframe into the fire-box.
The invention further consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and afterward particularly pointed out in the claims.
In order to enable others skilled in the art to which the invention most nearly appertains to make and use the same, the invention will now be described, having reference to the accompanying drawings, in which- Figure l is a View in elevation of furnacedoors constructed in accordance with this invention applied to a well-known form of marine engine. Fig. 2 is a view in elevation of a door and frame, the upper section of the door being open or let down upon the closed lower section. Fig. 3 is a similar view with the upper section lowered upon the lower section and the lower section thrown open. Fig. 4 is a vertical sectional View through the door and frame, illustrating both sections of the serai No. 686,516. tno man.)
door closed and showing the detiector-plates. Fig. 5 is a detail sectional View on the line 5 5 of Fig. 4. Fig. G is a detail perspective view of the lower plate of the upper detlector detached.
Like letters of reference indicate the same parts in all the figures of the drawings.
Referring to the drawings by letters, A indicates the boiler-head, provided with a suitable opening, in which is secured the doorframe B, having an outwardly projecting iian ge C, over which the door fits snugly when closed. The door is hinged to the door-frame B at one side by means of hinges D and is composed of two sections E and F, these sections being secured together by hinges G, so that the whole door maybe closed, the upper section alone opened, or both sections opened, as may be desired.
Fivoted to the sides of the door-frame B is a plate C', to which is secured the upwardlybent front edge II' of a bathe-plate or deflector comprising a lower plate Il, which is as wide as the door, projects into the fire-box, and normally rests in an inclined elevated position.
H2 indicates a plate secured upon the top of the plate II and separated therefrom by strips of asbestos H3, thus forming a passage between the plates I-I and Il2 for the air entering opening II4 in plate H. The side edges of the plates II H2 are inclined slightly toward the center and the side and front edges of plate IF bent downward, whereby air entering through the opening II'L and the door is deflected and prevented from coming into direct contact with the crown-sheet of the firebox or iues of the boiler. The pivots I of the hinge-plate are extended into bearings C2 outside of the flanges of the door-frame, and the plate is lprovided with an arm J, which has a threaded opening through which passes a bolt K, having on its outer end a handwheel L, whereby by turning the bolt inward or outward through the arm J, with the inner end of the bolt bearing against the door-frame, the detlector is adjusted in position higher or lower, as maybe desired. This deiiector also serves to conduct the cold-air draft to the center of the fire-box, thereby supplying oxygen at the proper point to complete the combus tion of the carbon of the fuel. A latch M,
IOD
pivoted to the lower section E of the door, engages a catch N to hold the door closed,l alug O preventing the rear end of the latch from rising 'too high. A catch P on the upper section of the door serves to receive the latcharm when turned vertically and support the upper section of the door when both sections are opened together, keeping it in line with the lower section E of the door. `A latch of any desired construction may be used to hold the upper section F of the door in its closed to the inside of the lower section E of the door by means of the bolts S, which in this instance are shown as securing also the hinges G, projects in a downwardly-inclined posilector, or guard to prevent clinker's or ashes from falling into direct contact with the doorsection E.
The provision of a door made in upper and lower sections permits of the firing of 'the furnace. without the necessity of opening the whole door, and inasmuch asf the door is partially opened all the time dduring the ring and during the time they engine is working steam a sufficientamount. of air is admitted to the fire to supply the necessary amount of oxygen to complete the combustion of. the
smoke and coal-gas, whereby the objectionable black smoke usually issuing from the stack is consumed and m-uch waste of fuel per section in line with the lower when itA isy desired tok open both sections together, this function being in addition to its usual funic-` tion. of keeping the lower section closed".
TheA advantages attending the: vuse of' this invention are many and will' be: readilyap'- parent from. the foregoing description',` and while the best means now known for carry'- ingl out the invention have been herei'ni-llusztrated and described it is not to be understood that the invention is restricted to the exact details of construction shown and described, but will include within its limit and scope any such slight changes or variations as might suggest themselves to the ordinary mechanic.
Having thus fully described the invention, what is claimed as new, and for which it is desired to secure Letters Patent of the United States, is-- position. Adelector-plateR,rigidly secured 1. The combination in a steam-boiler furnace with the door-frame, of a door comprising an upper and a lower section, the lower section being hinged at one side to the door- `frame, and the upper section hinged at its tion into the fire-box, serving as a fender,de4
lower edge to the upper edge of the lower section,A a catch projecting from. the doorframe, alatoh-lever hinged to the lower section of the door to engage said catch to h'old the door closed, and a catch secured to the upper section in vertical alinexnent with the pivot of the latch and adapted to hold the latch-lever in. a vertical positionV to rigidly secure the upper section in line with the lower section when: both are opened together, substantially as described.y
2. The combination in a steam-boiler furnace with the door-frame, of a hinged bar or lever pivoted in bearings thereon, a deflector-plate` having its outer edge turned upward and secured to the hinged plate. and
\ provided with an opening at the bend of the plate, asbestos strips secured` along the upperl edges of the plate, and an upper deflector-plate rigidly secured upon theasbestos strips leaving an air-passage between the upper and lower plates, the upper plate having its edges turned downward and its side edges incl-ined toward the center, to properly conduct and deiiect the air, substantially as described'.`
