UNITED S'mrns Barmvr OFFICE.
IMPROVEMENT IN VARIABLE EXHAUSTS FOR LOCOMQTIVE-ENGINES.
Specification forming part of Letters Patent No. 120,120, dated October 17, 1871.
To all whom it may concern:
Be it known that I, ORLANDO STEWART, of East Cambridge, in the county of Middlesex and in the State of Massachusetts, have invented certain new and useful Improvements in Variable Exhausts for Locomotive-Engines; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing makingapart of this specification, in which- Figure 1 is a plan view of the upper sideof my device. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical crosssection of said device on the line 00 x of Figs. 1 and 2, and Fig. 4 is a vertical longitudinal section of the same on the line 3 y of Fig. l.
Letters of like name and-kind refer to like parts in each of the figures. 1
My invention is an improvement upon a class of devices employed for changing the size of the exhaust-pipe of a locomotive so as to increase or diminish the velocity of the exhaust steam as it issues from said pipe and it consists, principally, in the peculiar construction and arrangement of the casing and pivoted wings, substantially as and for the purpose hereinafter specified. It consists, further, in the means employed for adjusting said pivoted wings to or from each other, substantially as and for the purpose hereinafter shown.
In the annexed drawing is shown the casing, having, preferably, a rectangular horizontal shape at its base A, from whence its sides B extend vertically upward in parallel lines, while its ends 0, at a point about one-third of the distance from their lower to their upper ends are curved outward and then upward, so as to increase longitudinally and horizontally the di mensions of said casing. Passing vertically up ward through the center of the casing from its lower end to the outward swell of the ends 0 is an opening, D, having a slightly-diminishing size upward, and having its corners rounded, while from the point where said ends swell outward to the upper end of said casing, said opening is rectangular in shape and conforms to the increase in size of the same, as shown in Fig. 4. Fitted to or within the recesses formed by the enlargement of the opening D are two wings, E,
which correspond to and fill said recesses so as to complete the sides of said opening upon a line with its lower portion, the inner faces of said wings being formed upon the same circle as the contiguous lower sides of said opening. In order that the size. of the upper end of the opening D may be diminished at will, the lower ends of the wings E are pivoted to or upon the sides B, so as to permit the upper ends of said wings to be moved toward or from each other and enable the space between the same to be diminished or increased in a corresponding degree. J ournaled horizontally within suitable bearings F, secured to or upon the rear side of the casing is a shaft, G, provided upon each end, immediately outside of said bearings, with a double arm, H. Pivoted within the upper end of each arm is one end of a flat bar, I, which from thence extends forward and has its opposite end pivoted to or upon the upper end of the adjacent wing. Similar connecting-bars K extend upward and forward from the lower ends of the arms H, and are in like manner pivoted to the upper end of the forward wing.
As thus arranged, it will be seen that by rotating the shaft G rearward the upper ends of the pivoted wings will be moved apart, and that by rotating said shaft in an opposite or forward direction said wings will be correspondingly moved toward each other.
The device as constructed is placed in the usual position within the smoke-stack of a locomotive, with the shaft G at its rear side, and extending transversely across the engine, the outer end of said shaft being projected beyond the smokestack sufficiently to enable it to receive a crankarm, from which a rod is extended rearward into the cab within convenient reach of the engineer, who is thereby enabled at will to quickly an d easily change the size of the exhaust-opening, and correspondingly vary the force and velocity of the exhaust steam.
The especial advantages obtained by this con struction and arrangement of parts are ease and efficiency of operation, combined with great strength and durability, in addition to which the device can be furnished at a comparatively small cost.
Having thus fully set forth the nature and merits of my invention, what I claim as new, is
1. The casing, composed of the base A, sides In testimony that I claim the foregoing I have B,ends G,and combined With the pivoted wings hereunto set my hand this 21st day of August, E, when the several parts are constructed and 1871.
arranged substantially as and for the purpose ORLANDO STEWART. specified.
2. In combination. with the elements above Witnesses: named, the shaft G, double arms H, and connec- GEO. S. PRINDLE, tions I and K, substantially as and for the pur- EDM. F. BROWN. (94) pose shown.
