DANIEL GOFF, 0F MILLVILLE, NEW JERSEY, ASSIGNOR TO GOEE GRAVITY IBOILER FEED COMPANY, OF CAMDEN, NEW JERSEY, A CORPORATION OF NEV JERSEY.

SMOKE AND GAS CONSUMER FOR LOCOMOTIVES.

To all whom t may concern:

Be it known that I, DANIEL Gori, a citizen of the United States, residing in Millville, county of Cumberland, State of New Jersey, have invented a new and useful Smoke and Gas Consumer for Locomotives, of which the following is a specification.

This invention relates to a new and useful induced draft and smoke consumer for boilers and more particularly to a consumer for use in connection with a locomotive type of boiler. i

1t has for an object to provide a construction wherein steam may be introduced at an advantageous point into the fire box to cause a more complete consumption of the products of combustion and furthermore serve as an efficient draft producing means.n

1t has-for a further object to provide a controlling or regulating mechanism, whereby the steam supplied to the fire box may be automatically governed for the purpose of proportioning the quantity of steam supplied to the condition of the fire.

1t further consists of other no-vel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my in* vention l have showin in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.`

Figure 1 represents a side elevation of a locomotive having 'a portion broken away, showing a fire box embodying my invention. Fig. 2 represents a section of a portion of the fire box taken on line zia-, Fig. 3. Fig. 3 represents a section of a portion of the fire box taken on line g/-gh Fig. 2. Fig. a represents a sectional plan of the fire box structure. Fig. 5 is a diagrammatic view of the automatic control mechanism. Fig. G represents a diagrammatic view of the steam discharge through the auxiliary ports.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: 1 designates a lire box of a locomotive type of boiler, the

same being formed by the inner shell 2 and the outer shell 3, the said shells forming between them the usual water leg 4.

5 designates a plurality of grate bars forming a of the fire box 1. It will be noted that a space 6 is provided at each side of the tire box between the shell 2 and the grate bars 5, in which-spaces is preferably placed a novel grate wall structure, now to be described. This structure consists, in the present instance, of a plurality of wings or grate bars 7, each having an inclined side 8 facing the interior of the fire box and also having a slot 9 formed therein for supporting purposes. These slots 9 are adapted to fit over a rod 10 which is fixedly secured to end' plates 11, therebyV forming with a second rod 12, a frame, which supports the several grate bars 7. It will be understood that the end plates 11 are fixed to vthe inner shell 2 by means of stay bolts 13 or like fastening means.

14e designates spacing members preferably cast integral with each grate bar 7, whereby the assembled grate structure consists of a plurality of bars 7, suitably spaced apart in order to permit the passage of steam or air to the tire. All of the grate bars 7 are preferably secured together by means of bolts 15 in order that they may be shifted as a unit. It will be seen that each of these structures may be swung as a unit about the rod 9 as a pivot and thus permit access to the space 6 in the rear thereof. These spaces 6 serve as a passage for air or steam and permit the same to pass back of and between the grate bars 7 into the tire box proper. In order tO cont-rol the passage of this air or steam and proportion the same to the draft desired, I preferably provide a damper 1T suitably pivoted at 18 and operated by means of a rod 19X and lever 19 suitably positioned within reach of the engineer in his cab. Air

is conducted to the spaces 6 through the 'A medium of a shield 20, preferably openended, located beneath the fire box and which acts when the locomotive is running, to direct a current of air beneath the grate 5 and also to the spaces 6, thus giving not only a direct upward draft through the grates but also a side draft between the grate bars 7 Attention is directed particularly to the construction of the side grate bars, since grate proper at the lower portion they are each preferably comparatively wide, thus giving a contact surface for the air to strike against and by mea-ns of which it is heated before entering` the combustion chamber. Furthermore, these grate bars 7 are assembled in close proximity to each other so that the air is retarded to an appreciable extent in passing between them and thus is held for a longer period in contact with the surface just referred to.

21 designates a pipe suitably supported on each side of the lire box 1 and beneath each space (3 and having therein a plurality of perforations 22 upwardly disposed in order to discharge steam into the spaces 6 and between the grate bars 7, as desired. It will be apparent from Fig. 2 of the drawings that, should it be necessary to cut down the supply of air or steam, it may b-e done by shifting the damper 17 as indicated in dotted lines, thereby decreasing the supply.

23 designates a box or chamber, comprising upper and lower compartments, denoted respectively by 24 and 25 and formed by a partition 2G longitudinally disposed in said box 23. There are preferably two of these boxes or chambers 23 oppositely located on each side of the fire box 1 and in close proximity to the top of the side grate bars 7, it being noted that each chamber is provided with a plurality of depending ports 27 comn'iunicating with compartment- 25, said ports being adapted to deliver steam into the fire box proper. The arrangement of the ports 27 is to be noted, as it is preferable to discharge the steam into the combustion chamber in a direction to promote combustion over the body of the fire and at the rear and for this purpose the ports 27 are positioned as shown diagrammatically in Fig. 6. The compartment 24 of each box 23, is suitably connected at each end by nipples 23 to the shell 2, thereby forming a communication with the water leg 4, whereby circulation of .water through one compartment of each box may be permitted. The lower compartment 25 of each box 23 has a pipe 29 leading thereinto, the said pipe leading from a suitable source of steam supply, whereby the compartments 25 serve as steam receivers and from which the steam is discharged through t-he ports 27 into the combustion chamber, at certain times. It will be noted that the boxes 23 are suitably secured to the shell between rows of stay bolts so that the usual construction of the fire box need not be altered and further'- more these boxes being located within the heat Zone, act as superheaters for the steam which is delivered therefrom and also promote the circulation of water in the boiler. In order to support the boxes in operative position, apertured lugs 30 are preferably formed integral therewith, through which suitable fastening means 31 are passed and engage the shell 2. The steam pipes 21 and 29 are suitably connected with a control mechanism operated preferably by the opening and closing of the furnace doors of the boiler and this mechanism will now be described.

32 designates a steam supply pipe suitably connected in the present instance to the dry pipe 33 of the locomotive and extending exteriorly of the boiler and connected with the control mechanism, which governs the supply of steam to the pipes 29 and 31. This control mechanism consists of a valve chest 3l into which the feed pipe delivers and it will be noted that the feed pipe 33 has branches 35 continuing therefrom and delivering live steam into valve cylinders 36 and 37, the two cylinders 36 and 37 controli ling the supply of steam to the main operating mechanism. This main Operating mechanism comprises a pair of valve cylinders 33 and 39 in each of which a piston valve 33x is located and connected respectively to the rods 40 and 4l-1. The rod 40 has a link e2 connected therewith at one end, while its opposite end is secured to a piston rod 43 connected to a piston 44 located in the cylinder 45 and adapted to be operated by steam pressure to shift the respective parts to move the piston valve 33X.

46 designates a pipe connected at a suitable point to the cylinder 33 and having connection also with the discharge pipes 29, whereby direct communication is established between the feed line33 and the pipes 29. A link t7 is connected to the rod 41 at one end, while its opposite end is secured to a piston rod 43 and operated by the movement of the piston 49, located in the cylinder 50. A pivoted link 42X connects the two links 4t2 and i7 and transmits movement of one to the other. The cylinder 45 receives steam through a pipe 51 connected to pipes 52 and 53, the former having connection with the cylinder 36, while the latter connects with the cylinder 37. A similar system of pipes 54, 55 and 5G form a communication between the piston cylinder 50 and the cylinders 36 and 37, the respective valves 57 and 53 forming a means to control delivery o-f steam to either cylinder' 45 or the cylinder 50, as the case may be. The valves 57 and 53 are, in the present instance, rotary valves, operation of which is controlled by levers 59 having connection through links 60 with the doors 61 of the furnace and it will therefore be seen that as the doors 61 are opened the valves 57 and 53 will be shifted and allow steam from the supply pipe 35 to pass to either or both systems, including the pipes 51 or 54.

G2 designates a main piston valve controlling the supply of steam to the steam chest 3-t, the said valve being controlled in the present instance by connecting the rod 63 through a link 64 to an arm 65 suitably pivoted at 66 to the shell of the boiler. This arm 65 has secured thereto a connecting rod 67 which passes interiorly of the cylinder 68 and is secured to a piston 69 adapted to be operated by steam pressure received through a. pipe 70, suitably connected to the pipe 54. A suitable check valve 71 is located in this pipe line 70, as will be apparent.

72 designates a counter-weight adjustably mounted on the arm 65 and adapted to re- Y turn the valve 62 to normal position after a movement of the same. Exhaust from the cylinder 68 is conducted by pipe 73 to the cylinder 37, where it discharges through port 74 to the atmosphere, it being noted that a valve 75 is located in the pipe 73K, by means of which the exhaust may be controlled and the time of t-he return of valve 62 to normal thus regulated. By thus throttling the exhaust from cylinder 68, the closing movement of the valve 62 may be regulated and the supply of steam to the pipes 21 and 29 gradually shut off after the furnace doors have been closed, thereby insuring' complete combustion of the added fuel. Should it be desired vto introduce steam through the pipes 21 and 29 at a time when the automatic control is not operating, I preferably provide a by-pass 76 having a valve 77 therein and connecting preferably between the pipe 35 and pipe 46.

78 designates a steam supply pipe leading from cylinder 39 to the discharge pipes 21 and it will be noted that this pipe 78 is connected by a conduit 79 with the pipe 46 in order to allow steam to enter both discharge pipes 21 and 29 irrespective of which cylinder 38 or 39 is furnishing live steam. Of course this is also true when the system is operated manually through the medium of the valve 77.

The operation of the device is as follows IVhen the fuel is placed upon the fire it is necessary or desirable to not only introduce air through the grate bars in order that the fuel may be properly ignited, but also to supply a suitable amount of steam in order that the smoke and gases will be consumed and the means which I have here shown take care of this automatically, but

I have also provided a manual means for controlling the admission of steam in order to continue supplying the same should the automatic control means have closed down before suicient amount of steam has been induced for the purpose intended. The automatic means for controlling this supply of steam is governed in the present instance by the movement of the furnace doors 61 and as soon as they are opened both rotary valves 57 and 58 are shifted so that the live steam from the feed pipe 35 has free flow through the cylinders 36 and 37 to the pipes 55 and 56 and thence by way of pipes 54 and 70 into the cylinders 50 and 68. The steam entering cylinder 68 raises the piston 69 and through its connections shifts valve 62 to admit steam to the steam chest 34. At the same time the piston 49 has been shifted to open valve 38 of cylinder 397 thus allowing free flow of steam to conduit 78 from which it is delivered to pipes 21 and 29.

From the pipes 21 and 29 the steam enters the combustion chamber directly, while from the pipes 29 it enters the compartments 25 and discharges through the ports 27 into the combustion chamber, there mingling with the products of combustion and forming a more complete combustion, producing a draft to draw the smoke and gases away from the door and toward the stack. As soon as the furnace doors 61 are closed, after a stokingv operation, the rotary valves 57 and 58 are returned to normal position and establish communication between the live steam of pipes 35 with the pipes 52 and 53, which latter direct the same through the pipe 51 to the cylinder 45 and in this latter cylinder t-he piston 44 is moved upwardly to shift its piston valve 38X to permit live steam to pass through the pipe 46 to the pipes 21 and 29. During this movement the piston 49 has returned and closed the admission of steam to cylinder 39 while the piston 69 is gradually returning, owing to the retarded exhaust of cylinder 68. This steam is still admitted through valve 62 and supplied in decreasing quantity to the discharge pipes 21 and 29, its point of cut off being of course predetermined by the adjustment of valve 75. It will be noted that if it is desired to admit steam to the combustion chamber thro-ugh but one of the sets of pipes 21 and 29, I have provided a pair of valves 7 9 and 80, making this possible and whereby the admission of steam may be manually controlled to either point of discharge.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in t-he statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
