SEPARATOR FOR APPARATUS FOR REMOVING DUST.

' Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed May 26, 1905- Serial No. 262,312.

To all whrmt it may concern.

Be it known that I, DAV-ID THOMAS KENNEY, a citizen of the United States of America, and a' resident of the borough of North Plainfield, county of Somerset, and

State of New Jersey, have invented certain" new and useful Improvements-in Separators for Apparatus for Removing Dust, of which the following is a specification.

This inventlon 1s an improvement 1n the separator dlsclosed in Letters Patent of the United States No. 739,263, granted to me September 15, v1903, and is intended espe'- cially, but not necessarily, to be used in con- 'nection with dust-removing apparatus simiof dust so completely that the air'after passingthrough the separator may be permitted to pass directly through-the valves and into the cylinder of a suction-pump without danger of causing material injury or undue wear to the pumping apparatus.

The separator is so organized that it will remove and store within it a considerable amount of dust and require openin clearing of the strainer, and emptying on yat lon The separator is also arranged ciently cleared.

In the accompanying two sheets of drawings, which form apart of this application, Figure 1 is a vertical section on the line I I of Fig. 2 through a separator embodying my invention. Fig. 2 is a top view of the se arator.

The separator, as illustrated, conslsts of a cylindrical casing or shell 1, which may be supported by means of a flange 2 overa flooropening or inany suitable manner. The upper rim of the casing is riveted to an annular top plate 3, and to this is secured a removable top' late 4 by means of buttons 5, through whic screws 6 pass and are clamped by wingnuts 7. Athroat 8 with a downwardly-o ening'mouth lies within the upper part 0 the casing of the separator and is attached to the In order to reduce weight in this removable top plate, it is preferably only large enough to cover that part of the casingwhich lies within the throat and lap the annular top plate which covers the casing exterior to the throat. An inverted bag 9 of filter-cloth, which for strength is preferably of globular form when distended,

forms a cloth strainer of considerable area and lies within the throat and across the mouth of the throat. The open end of the strainer-bag is connected to the periphery of the throat, preferably by being lapped over an outwardly-turned flange 10- around the downwardly-opening mouth of the throat,

and is conveniently secured by drawing a string "through a hem at the mouth of the bag and tying. The bag is held within the throat by a coil-spring 11, which is suspended from a hook projecting'from the under side of a plug 12, which is screwed in the top plate.

This suspension for the bagis therefore readily removable, for by unscrewing the plug the spring can be detachedand the strainer-bag released without otherwise opening or taking apart the separator, so that the bag can'be turned inside out and be cleaned.

As illustrated, the throat is wholly within the casing of the separator and is of smaller diameter, so that an annular space is formed between the exterior walls ofthe throat and within reach at the opening in the bottom of the casing, where it can be seized and jerked to agitate the -strainer-bag and shake the dust therefrom. The separator is provided with a tangentially-directed inlet 15, which opens into the annular space between the throat and easing. An outlet 16 leads from the throat-chamber .through the top late;

In using the separator a partia vacuum s created in the throat by a pump which 1s connected to the outlet, and dust-removing a paratus is connected by ipes to the inlet. The dust-laden air enters-t e casing near the top in a tangential direction, encircles the casing in a spiral course downwardly 1n the annular chamber with arrested velocity, and

while passing through this portion of the separator.

separated from the air as it passes therethrough. This strainer-bag may, if desired, be stiffened by bands 17. I

What I claim as new, and desire tosecure by Letters Patent of the United S1 ates, is-

1. A separator for dust-removing apparatus, consisting of a casing, a downwardlyopening throat within the casing forming an annular chamber between the exterior walls of the throat and the casing, a strainer-bag through which the air to be purified passes located within the throat, having its edge connected to the peripheral wall of the throat, an inlet connecting to the annular chamber, and an outlet from the throat, substantially as described.

2. A separator for dust-removing apparatus, consisting of a casing, -a threat downwardly opening into the .casing, a cloth strainer-bag through which the air to be purified passes located within the throat aving its edge connected to the peripheral wall of the throat, a suspension for the strainer-bag, and means for agitating the strainer-bag, substantially'as described. g

3. A separator for dust-removing ap aratus, consisting of a casing, a throat own- Wardly opening into .the casing, a cloth strainer-bag through which the air to be urified passes located within the throat iiaving its edge connected to the eripheral Wall of the throat, and a removal) e suspension for the strainer-bag, substantially as described.
