TRCTION-ENGINE SPECIFICATION forming part of Letters Patent No. 378,502, dated February 28'I 1888.

Application led September 80, 1887. Serial No. 251,139.

To all whom it may concern..-

Be it known that I, ANDREW K. GIBsoN, a citizen of the United States, residing at Kimbolton, in the county of Guernsey and State of Ohio, have invented a new and useful Improvement in Traction-Engines, of which the following is a specification.

llIy invention relates to an improvement in horizontal engines such as are employed on traction-engines, and my improvements are also adapted to bel applied to locomotive-boilers; and they consist in the peculiar construction and combination of devices, that will be more fully set forth hereinafter', and particularly pointed out in the claim.

The accompanying drawing is a perspective view illustrating a portable engine provided with my improved device.

Arepresents a horizontal steamboiler, which is provided near opposite ends with a pair of steamdomes, B and B. On the upper side of 'cach steanrdoine is a safety-valve, C.

D represents the cylinder of the engine, and E represents the steanrfeed pipe, which coinmunicates with the steam-chest F to supply steam thereto from the boiler. The pipe E is connected to one of the steain-cloines-by a pipe, G, which is provided with a valve, H, adapted to be opened or closed by the engineer, so as to establish or cut off communication between the dome B and the pipe E.

I represents a steanrpi pe which connects the dome B with the pipe G at a point between the valve H and the pipe E. The said pipe I is provided with a valve, K, which is similar to the valve Hin pipe G,and is adapted to be opened or closed by the engineer, so as to establish or cut off communication between the dome B and the pipe E.

The object of my invention is to provide means wherebythe engine may be always su pplied with dry steam unrnixed with water, whether the boiler is arranged in a horizontal (No model.)

plane or in an inclined position, and the operation thereof is as follows: Vhen the boiler is in a horizontal position, the valve K is closed and the valve II is opened, and thereby steam from the dome B is caused to pass through the pipes G and E into the steam-chest, and the also,when the engine is in an inclined position, with the front end of the boiler lower than the rear end thereof. When the engine is arranged in an inclined position, with the front thereof, the valve H is closed, so as to cut ott communication between the dome B :and the steam-pipe E, and consequently preventwater from the said dome from entering the said pipe, and the valve K is opened, so as to establish communication between the dome B and the pipe E, and thereby supply the engine with dry steam from the elevated dome B.

My invention is especially adapted for use on the boilers of portable and tractionengines, and it may also be advantageously employed on boilers of locomotive-engines.

Having thus described my invention, I claim- The combination of the boiler having the steam-domes at opposite ends, the steam-engine having the vertical steam-pipe E, provided with the governor, the pipe G, connect` ing one of the domes to the pipe E, the pipe I, connecting the other dome to the pipe G, the cut-off valve K in the pipe I, and the cutoff valve H in the pipe G at a point between the juncture of pipe I with said pipe G :and the adjacent dome, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ANDREW K. GIBSON.
