SPENCER OTIS, OF CHICAGO, ILLINOIS.
STEAM-LOCOMOTIVE.
SPECIFICATION forming part of Letters Patent No. 683,658, dated October 1, 1901.
Application filed March 21,1901. Serial No. 52,179. (No model.
To all "whom it nutty concern:
Be it known that I, SPENCER OTIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam-Locomotives, of whichthe following is a specification, reference being had therein to the accompanying drawings.
This invention relates to the construction of the front end or smoke-box of locomotives and to the extension of said smoke-box to inclose the cylinders and steam-chests thereof within said smoke-box.
The object of my invention is to provide said sm eke-box with passages around the cylinders through which the hot gases and products of combustion are directed under and around said cylinders to keep them hot and prevent condensation of steam therein.
It relates also to means of regulating the amount of hot gases circulating around said cylinders and steam-chests.
The invention will first be described in connection with the accompanying drawings, in which- Figure 1 is a transverse vertical section of a locomotive smoke-box constructed in accordance with myinvention. Fig. 2 is a longitudinal vertical central section of the same. Fig. 3 is a horizontal sect-ion of the same on line was of Fig. 1. The hot gases indicated by arrows in each figure show the hot currents descending close to the walls of the smoke-chamber and ascending in its center alongside of the exhaust-nozzle. Figs. 4, 5, and 6 represent a modification of the smokebox. Fig. 4 represents a transverse vertical section, Fig. 5 a central longitudinal vertical section, and Fig. 6 a horizontal section of the same on line y y of Fig. 4. The arrows in each figure indicate the current of hot gases descending between the cylinders within the smoke-box, passing under said cylinders, and ascending alongside of the cylinder-walls and between said walls and the walls of the extension of the smoke-chamber.
In said drawings, A represents the body of a tubular boiler of any suitable construction, and O the smoke-box thereof, which is of larger diameter than usual and contains the steam-cylinders D, one of which is shown provided with a valve-cylinder cl for a pistonvalve and the other with a steam-chest cfor a slide-valve. The steam-pipes leading from the boiler to the steam-chests are shown at E,
and their lower ends are secured to the steamchests. The cylinders are supplied with saddles F, as usual, which saddles have a central openingf for the passageof the exhaust nozzles G and of the hot gases alongside of said nozzles and direct them to the smokestack H. The length of the smoke-box is preferably the same as that of the cylinders, so that it can be secured to the flange of the cylinder-heads, or it may be made to extend over the cylinder-heads.
To regulate the proportion of hot gases which pass through the opening 19 and which are directed around the bottom of the steamcylinders through the passages m, suitable dampers h are located between the steamchests and the horns of the saddle. In the drawings the dampers are shown pivoted to the steam-chest; but they may be pivoted to the horns of the saddle, or sliding dampers may be used. The lower part of the smokestack H is also provided'with a damper 7a, which may be opened to allow the hot gases to go direct from the flues to the stack.
The steam-chests and cylinders may be inclosed in sheets '5, of metal or of asbestos. As the lower part of the smoke-chamber acts asa cinder-box, hand-holesj are placed in the walls of said box, either in the ends, as shown, or in the bottom.
In the modification shown in Figs. 4, 5, and 6 there is placed in the smoke-box a plate K, which is nearly horizontal, but slightly i11- clined toward its front end. The rear end of said plate is secured to the tube-sheet of the boiler slightly above said tubes to deflect downwardly the hot gases issuing from the tubes. They are thereby directed through openings Z alongside of the exhaust-nozzle G downwardly between the two cylinders D, through a passage m, under said cylinders, between them and the bottom of the smokebox 0, and upwardly between the walls of said smoke-box and cylinders to the opening 'lt above the plate K and beyond the upper end of the nozzle G.
The above-described construction can be used for either single or compound engines; but the necessity of a compound engine will 2. The combination of a portable steamboiler and its smoke-box at the front end, cylinders and valves therefor having their top on a lower level than the bottom of said boiler, the said smoke-box completely surrounding said cylinders and valves, whereby the products of combustion are conducted downwardly along one side of each cylinder and valve, thence under the cylinder, and up wardly on the opposite side, to the smokestack substantially as described.
3. The combination of a portable steamboiler and its smoke-box at the front end, cylinders and valves therefor on a level below the bottom of the boiler and completely surrounded by said smoke-box, with smokeflue dampers in said box, the products of combustion being conducted downwardly within said smoke-box to one side of the cylinders and valves, and thence upwardly on the opposite side, to the smoke-stack substantially as described.
In testimony whereof I affix my signature in presence of two Witnesses.
SPENCER OTIS.
