Specification of Letters Patent.

Patented Oct. 3, 1911.

Application filed July 22, 1910. Serial N 0. 573,246.

To all whom it may concern:

Be it known that 1, WILLIAM E. CooNnY, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Adjustable Cleaners and Smoke-Consumers for Locomotive Smoke-Boxes, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which itappertains to make and use the same.

The objects attained by the invention are primarily the equalization of the draft through the boiler -fiues by providing suit able draft passages therefor through the smoke box, the walls of which are so arranged as to permit of free circulation through all the flues without choking any of them with cinders, or with the products of combustion, and whereby the free consumption of coal will be permitted and the draft will tend to remove all accumulations of soot or cinders in the fiues and passages and prevent deposit thereof in the smoke box. By the improved construction hereinafter described the life of the boiler is increased and its action rendered more useful in an efficient and practical manner.

The invention is designed to provide means for accomplishing the following results: the removal of all obstructions to the free action of the draft, through the smoke flues and smoke box, and thereby to equalize the draft through all the tubes, and avoid the retarding of the draft at any point in the smoke box, and in particular to prevent the choking of the upper fines; to so arrange the draft passages in the smoke box that the draft will scour the smoke box and prevent the deposit therein of soot and cinders; to assist in consuming the soot and smoke by relieving the flues and grate from back pressure; to relieve the strain upon the bottom flues in the boiler by insuring free action of the draft in the upper fines, and by equalizing the draft to reduce the amount of coal consumed, and keep the fire clearer and the steam pressure steadier and to dispense with projecting castings or pockets in the front end, heretofore employed as cinder catchers; to avoid the overheating and warping of steam pipe joints in the smoke box, due

to deposits of hot cinders thereon, which can only be removed with difliculty.

The invention further comprises the forms of construction and arrangement of said walls and the means for adjusting the relative sizes of openings in said passages, and in the screens provided for preventing the escape of incandescent cinders or sparks from the stack, as hereinafter described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a longitudinal section of the front end of a boiler showing the arrangement of passages in the improved device. Fig. 2 is a front view thereof with the head or closure removed showing the arrangement of the screen and deflecting walls of the draft passage. Fig- 3 is a detail view showing the means of attaching certain of the adjustable plates.

In these views 1 is the boiler, 2 is the boiler head, 3, 3, the fiues, 4 is one of the steam pipes for live steam, 5 is the exhaust steam nozzle which is adapted to discharge into the smoke stack 6 vertically above it, for the purpose of accelerating the draft.

7 is the smoke box to which the steam nozzle and smoke stack are attached. The smoke and products of combustion from the boiler flues 3, 3, are not led directly to the smoke stack 6, but first traverse the smoke box 7 and the smoke from the upper and central lines is deflected downward by an inclined partition or wall 8, and passes through a horizontal passage P formed between a perforated steel plate 9 above and a horizontal wall 10. A portion of the smoke passes upward through the perforated plate 9.

An inclined wire screen 11 connects the forward end of the perforated plate 9 with the top of the smoke box, and the smoke and gases from combustion pass readily therethrough but cinders and large incandescent masses of soot will not pass through but will remain in the lower part of the smoke box until by churning action of the draft they become fine enough to pass through the screen.

The draft from the central and lower fiues is separated by means of the inclined transverse walls 12 and-18. These walls are inclined in opposite directions forming a V with the points toward the rear. The draft which follows the plate 13 is deflected to the bottom of the smoke box and passes to its forward end where it is guided to the screen 11 by means of the transverse walls 1 1 and 15 wall 14L being downwardly and forwardly inclined, and wall 15 joined thereto being upwardly and forwardly'inclined. Plate P is slidable 011 plate 12 and regulates the size of passage P.

By means of the central passage I the draft from the upper and central flues is deflected with very little resistance into the smoke box 7 and it exerts a scouring action upon the horizontal walls so that they are kept perfectly clean from deposits. The draft from the lower fiues also serves to scour the bottom of the smoke box, and the deflecting plates or walls 1 1 and 15 serve to direct the draft against the front wall 20 of the smoke box and thence upward to the screen 11, thus producing a churning action which quickly breaks up cinders or masses of soot so that all products of combustion can pass through the screens in a finely divided state free from large or dangerous sparks. This arrangement of draft passages serves to make the draft instrumental in scouring and keeping them clean, and prevents deposit in the forward end of the smoke box. It also provides means for securing perfect combustion of fuel upon the grate and obtains economy in its use and also the amount of smoke and soot produced is much reduced.

The horizontal screen 9 is preferably formed of perforated sheet metal to give a smooth surface so as to avoid friction and retarding of the draft. The plates 12 and 13 and 1 1 and 15 can be made adjustable to increase or decrease the relative sizes of the passages, by means of bolts 21, 21, located in slots 22 in the plates, and in this manner the draft can be closely regulated. Plate 12 is connected with plate 10 by means of the intervening plate 50 having a downwardly turned flange at its outer edge, such.

flange being provided with a slot for the reception of a securing bolt 51.

The plates 13 and 15 are positioned angularly to give the required direction to the draft.

Having described the invention what I claim as new and desire to secure by Letters Patent is;

1. In combination with a locomotive boiler, its fiues, smoke box and vertical exhaust nozzle, and smoke stack, therein, a horizontal transverse plate beneath the nozzle opening, and a parallel horizontal screen above the plate, said plate and screen forming the walls of a horizontal draft passage, an inclined screen connecting the forward end of said horizontal screen with the top of said smoke box, an inclined plate connecting the rear end of said screen with the forward end of the boiler above the flues, a

plate rearwardly and downwardly inclined .boiler and tlues therefor, a smoke box, a

vertical exhaust nozzle and smoke stack in said smoke box, of a horizontal screen and a parallel plate spaced therefrom, and encircling said exhaust nozzle, to provide a horizontal passage, angular deflecting plates in said smoke box, said plates attached to said parallel plate and constructedand arranged to direct the draft from the upper and central flues into said horizontal passage and to direct the draft from the lower tubes along the bottom of the smoke box, and an upwardly inclined screen connecting the outer end of said horizontal screen with the upper and front end of the smoke box.
