Specification of Letters Patent.

Patented Feb. '13, 1912.

Application filed June 10, 1911. Serial No. 632,372.

To all whom 2'25 may concern:

Be it known that I, JOSEPH DVORAK, a subject of the Emperor of Austria-Hungary, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have in vented certain new and useful Improvements in Smoke-Separators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to smoke separators designed for large and small manufacturing plants located in cities where smoke ordinances make it prohibitive for the free dis charge of smoke and gases from stacks and chimneys.

The primary object of my invention is to utilize water, air or steam under pressure for condensing smoke and removing dust, ashes, dirt and unconsumed products of combustion from the smoke prior to its es cape, thereby preventing buildings and other property from being injured by deposits of dust and other foreign matter.

Another object of this invention is to utilize a series of water ejectors for thoroughly saturating the smoke with water or steam, whereby the condensate will contain all the destructive properties of smoke emitted by a stack or chimney.

A further object of the invention is to provide an apparatus embodying structural elements that are compactly arranged, inexpensive to install and highly eflicient for the purposes for which they are intended.

With the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein there are illustrated the preferred embodiments of the invention, but it is to be understood that the structural elements' thereof are susceptible to such changes in the size, shape and manner of assemblage as fall within the scope of the appended claims.

In the drawings :Figure 1 is a longitudinal sectional view of a smoke separating apparatus especially designed for large manufacturing plants, Fig. 2 is a view of one end of one of the steam or air ejectors partly broken away, Fig. 3 is a view of the opposite end of the ejector.

Like numerals of reference designate corresponding parts throughout the several views.

The reference numeral 1 denotes an elbow in communication with a stack orchimney, said elbow having the upper end thereof provided with a peripheral flange 2 and riveted or otherwise connected, as at 3 to the flange 2 is a peripheral flange 4, carried by the small end of a horizontal frusto-conical shaped hood 5, the large end of said hood having an exhaust pipe 6. This pipe has an opening 7 and in communication with said opening is a drain pipe 8 having the upper end thereof flanged and secured to the pipe 6 by rivets 9 or other fastening means.

10 denotes a water supply pipe extending through a nipple 11, carried by the elbow 1, said water supply pipe extending longitudinally and centrally of the hood 5. The pipe-10, adjacent to the nipplell, has an ordinary type of gate or globe valve 12, whereby the supply of water to the hood can be easily controlled. The portion of the pipe within the hood is eXteriorly screw threaded, as at 13 and arranged upon the threaded end of said pipe is a blower or pump and a series of water ejectors, said ejectors being of different diameters and stepped in their order, whereby the peripheral edges of said ejectors will be in a plane substantially parallel with the inner walls of the hood 5.

The blower or pump comprises a cupshaped casing 14 having the bottom thereof provided with an opening 15 and the walls of the opening are screw threaded whereby the casing can be easily screwed upon the pipe 10. The casing has an inlet nipple 16 adapted to be connected by a union or other coupling 17 to a steam. or air supply pipe 18. This pipe extends through an opening 19 provided therefor in the hood 5, and adjacent to said hood the pipe has an ordinary type of globe valve 20. This valve is adapted to control the admission of steam or air to the casing 14. Screwed upon the pipe 18 into the open end of the casing 14 is a deflector head 21 adapted to engage the edges of the casing 14. The peripheral edge of the deflector head 21 is provided with radially disposed grooves 20 adapted to disseminate steam or air ejected from the casing 14.

The series of water ejectors consists of cup-shaped casings 23 having the bottoms thereof provided with openings 24 with the walls of said openings screw threaded, whereby the casings can be screwed upon the pipe 10. The pipe 10 has an opening 25 opening into each casing, whereby water will be admitted to each casing. Secured upon the pipe 10 to engage the edges of the casings are deflector heads 26 similar to the head 21, said heads having the peripheral edges thereof grooved, as at 27 whereby the water admitted to the heads will be pro jected outwardly from the casings in sheets toward the walls of the hood 5.

When the smoke from the elbow 1 enters the hood 5, it can expand within the hood, a draft being set up by the blower or pump that causes the smoke to rapidly enter the hood 5. Then the smoke encounters the steam or air ejected by the peripheral edges of the steam ejectors, and the water from the water ejectors, the smoke is driven toward the side walls of the hood 5 and it is upon these walls that the condensate collects and gradually travels toward the opening 7 into the drain pipe 8. The condensate, produced by the smoke commingling with the steam and water, contains all the dust, ashes, carbon'products, soot, unconsumed products of combustion and foreign matter originally held in suspense by the smoke, consequently only steam will escape from the exhaust pipe 6.

The advantage of the stepped arrangement of the steam and water ejectors is that the smoke is carried toward the walls of the hood 5 and these walls collect the condensate, it being practically impossible for the smoke to escape through the hood 5, without encountering the radiating sheets of steam and water from the ejectors.

In the preferred form of construction, the

condensate drains toward the exhaust of the stack or chimney.

The apparatus is constructed of light and durable metal. and it will of course be understood that it is applicable to locomotives and various types of power producers.

hat I claim is 1. A smoke separator comprising a frustoconical hood, an elbow for connecting the contracted end of the hood to a stack, a liquid supply pipe extending longitudinally with respect to said hood and provided with spaced openings constituting outlets, a se ries of spaced liquid ejectors mounted upon said pipe and each surrounding an outlet, the diameters of the respective ejectors increasing to provide a series of ejectors having the peripheral edges parallel with the inner face of the hood, and a blower mounted upon said pipe ahead of the ejectors in the direction of flow of the gases.

2. A smoke separator comprising a frustoconical hood, an elbow for connecting the contracted end of the hood to a stack, a liquid supply pipe extending longitudinally with respect to said hood and provided with spaced openings constituting outlets, and a series of spaced liquid ejectors mounted upon said pipe and each surrounding an outlet, the diameters of the respective ejectors increasing to provide a series of ejectors hav ing the peripheral edges in a plane parallel with the inner face of the hood.

In testimony whereof I affix my signature in the presence of two witnesses.
