ALEXANDER MORTON, OF GLASGOW, SOOTLAND.

Letters Patent No. 86,030, dated January 19, 1869.

IMPROVED INJECTOR The Schedule referred to in these Letters Patent and making part, of the same.

To all whom. it may concern it known that l, ALExANDnn Mon'ron, of the city of Glasgow, in the county of Lanark, Scotland, have invented a new and improved Apparatus for Improving the Lateral Action or Induction of Fluids generally; and I do hereby d clare that the fi llowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention consists, mainly, in the arrangement of apparatus by which certain currents of either clastic or non-elastic fluids may communicate a simultzv neous motion to other such fluids by their lateral action or induction through'atube or tubes, increasing in area in a'certain ratio to the diminishing pressure of the escaping or acting fluid; and

The objects and advantages to he gained by the use of this said invention are, its application to steam-engines, particularly for producing a vacuum, or partial vacuum, on'the exhaust side of their piston or pistons, and to the raising of water for these engines, and other purposes generally; and also injectors, whereby such machines are made more economically than has heretofore been the case.

In the accompanying drawjngs- Figures 1 and 2 represent longitudinal sections of my invention.

Similar letters of reference indicate corresponding parts.

A is the exhaust-pipe of one cylinder of a steamengine, and B, that of the other, and G, the inductiontube, whilev D is the injection branch-pipe, through which the condensing or injection-water enters the apparatus, which in fig. 1 takes the form of central jet at the nozzle E.

This central jet of water through the nozzle E is maintained, when the engines are Working, by the alternate discharge of steam from the cylinders, at the pipes A and B, and on starting the engines, the jet of water may be produced by a. central jet of steam through the pipe F, and duplex or cased nozzle FQniirect from the boiler, regulated by a valve or cock, which may be closed as the engines increase in speed.

The water passing through the cent-re of the apparatus, gets an impulse from the annular jet of steam at A, which produces a vacuum in the pipe B, and a similar impulse produced from the pipe B produces a vacuum in the pipe A, respectively and alternately, as the steam escapes from the two cylinders of the engine or engines.

\Vhcu a head of water, of about seven or eight feet, can be obtained, the central steam-jet at F may be dispensed with altogether; or when a pump is used for forcing the central jet of water through the nozzle E and apparatus, it may be advisable or necessary to use a reg[dating-spindle in theplace where the nozzle F is placed, as shown at G in tig. 2, so that it may be adjusted to regulate the inlet-flow of water in an annular jet or stream, to suit the speed of the water from the pump, or quantity required.

Although in these arrangements mentioned, the exhaust-pipes A and B have been described as conveying the exhaust steam from two different cylinders, yet it is to be understood that they may each convey the exhaust steam from the different ends of the same cylinder when the improvements are to be applied to singlecylinder engines.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The arrangement, within the tube containing the exhaust-pipes A B, and the injection branch-pipe D, of the induction-tube 0, central nozzle E, pipe F, and duplex or cased nozzle l substantially as herein shown and described.

The above specification of my invention signed by me, this 18th day of March, 1868 ALEXANDER MORTON.
